1. Field of the Invention
The present invention relates to authentication devices, and more particularly to authentication devices provided in gaming machines.
2. Background Information
An authentication device reads authentication data from an authentication object which approaches or touches a predetermined authentication position, and then performs an authentication process based on the authentication data. A biometric authentication device is one such authentication device. See, for example, Japan Published Patent Application 2002-318648. A biometric authentication device uses biometric characteristics (a fingerprint pattern, a retina pattern, a vein pattern, etc.) as authentication data which can identify individuals. More specifically, when a body part (authentication object) that includes biometric characteristics approaches or touches a sensor (predetermined authentication position) of the biometric authentication device, the biometric authentication device reads the biometric authentication data (fingerprint, retina, or vein pattern data, etc.) from the body part through the sensor. Then, the biometric authentication device performs an authentication process based on the read biometric authentication data, and determines whether or not the person who has the biometric characteristics is a person who has proper authority. For example, if the person is determined to be a person with the proper authority, he will be allowed to proceed with the specific process or operation; however, if this person is determined to not have the proper authority, he will be prohibited from proceeding with the intended process or operation.
A device installed in a non-contact IC tag reader unit is known as another authentication device. See Japan Published Patent Application 2001-325572. When a non-contact IC tag (authentication object) approaches or touches a predetermined authentication position which is provided on the surface of an authentication device installed in a non-contact IC tag reader unit, the non-contact IC tag transmits authentication data. The non-contact IC tag reader unit receives the authentication data, and performs an authentication process based on the authentication data to determine whether the non-contact IC tag is valid or not. If the IC tag is determined to be valid, the person in possession of the IC tag will be, for example, allowed to proceed with a specific process or operation, or perform data communications with the non-contact IC tag. On the other hand, if the non-contact IC tag is determined to be invalid, the person in possession of the non-contact IC tag will be prohibited from performing a specific process or operation, and prohibited from performing data communications with the non-contact IC tag.
A region (hereafter referred to as an authentication space) is provided on the surface of every conventional authentication device, and is used as the authentication position at which the authentication object is to approach or touch the surface of the authentication device. For example, gaming machines and portable electronic appliances (such as notebook computers and cellular phones) are generally equipped with a display. There are demands to increase the screen size of the display on these products. On the other hand, when an authentication device is installed in these products, it is desirable that the authentication position is placed where a user can easily operate the device, e.g., on the front surface of the product. However, the screen size of the display must be limited in order to provide an authentication space on the front surface, because the display screen is usually located on the front surface. As a result, further increasing the screen size of the display is difficult. Compatibility between the allocation of authentication space and an increase in screen size is difficult, particularly when a product whose miniaturization is strongly desired, such as a portable electronic appliance, is equipped with an authentication device.
In view of the above, it will be apparent to those skilled in the art from this disclosure that there exists a need for an improved authentication device, and a gaming machine equipped with the authentication device, in which an authentication position can be allocated on the surface in which the screen of a display unit is provided, without limiting an increase in screen size of the display unit. This invention addresses this need in the art as well as other needs, which will become apparent to those skilled in the art from this disclosure.
SUMMARY OF THE INVENTIONAn authentication device according to the present invention preferably comprises a display unit which includes a screen and which displays an image on the screen; an authentication data input unit which is located on the rear side of the display unit or the vicinity thereof, and which reads authentication data from an authentication object approaching or touching the screen; and an authentication unit which performs an authentication process based on the authentication data read by the authentication data input unit. Here, it is preferable that the authentication data is biometric authentication data which shows biometric characteristics (such as fingerprints, retinas, or veins) that can identify individuals. In this authentication device, the authentication data input unit is located on the rear side of the display unit or the vicinity thereof, and the authentication position exists on the screen of the display unit. Therefore, the authentication position can be provided on the surface in which the display unit is mounted, without limiting any further increase in the screen size of the display unit.
In the above-described authentication device according to the present invention, the authentication data input unit preferably includes an electromagnetic wave irradiation unit which irradiates the authentication object with electromagnetic waves through the screen of the display unit; and an electromagnetic wave detecting unit which receives an electromagnetic wave transmitted from the authentication object in response to the electromagnetic wave applied by the electromagnetic wave irradiation unit, and which reads the authentication data from the received electromagnetic wave. For example, the electromagnetic wave irradiation unit irradiates a portion of a person's body (the authentication object) with electromagnetic waves (in particular, infrared rays). Furthermore, an electromagnetic wave detecting unit detects the electromagnetic wave radiated from the body portion in response to the irradiation of the electromagnetic wave irradiation unit, and then reads biometric authentication data of the body portion from the detected electromagnetic waves. Alternatively, the electromagnetic wave irradiation unit, for example, transmits specific data in order to request authentication data from an authentication data storage device (the authentication object), using electromagnetic waves. The authentication data storage device which received this data then transmits the authentication data using wireless communications. The electromagnetic wave detecting unit reads the transmitted authentication data.
Alternatively, the authentication data input in the above-described authentication device according to the present invention unit may include a magnetic field generating unit which generates a magnetic field in the vicinity of the screen of the display unit in order to supply electric power to the authentication object with the magnetic field; and a receiving unit which uses the electric power provided from the magnetic field to read the authentication data when the authentication object transmits the authentication data. Here, it is preferable that the authentication object is an authentication data storage device (such as an IC tag).
The above-described authentication device according to the present invention preferably comprises a detection unit which detects the authentication object when it approaches or touches the screen of the display unit. In that case, the electromagnetic wave irradiation unit further preferably irradiates electromagnetic waves in response to the output of the detection unit. Alternatively, the magnetic field generating unit generates a magnetic field in response to the output of the detection unit. Thus, the electromagnetic wave irradiation unit and the magnetic field generating unit operate when the authentication object approaches or touches the screen of the display unit. In other words, the electromagnetic wave irradiation unit and the magnetic field generating unit activate and generate the electromagnetic wave and the magnetic field, respectively, only when necessary. Accordingly, the device can easily save more energy. Further preferably, the detection unit is a transparent touch sensor which is provided on the screen of the display unit. Here, the touch sensor can detect contact of the authentication object with the screen of the display unit. Specific examples of such touch sensors are analog capacitive coupling touch sensors, and touch sensors which use ultrasonic waves (surface acoustic waves).
The display unit preferably displays a guidance image which shows the position (hereinafter referred to as the authentication position) on the screen of the display unit at which the authentication object is to approach or touch the screen, in the above-described authentication device according to the present invention. Thus, a user can easily locate the authentication position on the screen. Further preferably, the display unit displays the plurality of the guidance images that show different authentication positions on the screen, and the authentication data input unit reads authentication data from the authentication object which approaches or touches one of the plurality of the authentication positions. Here, the authentication data input unit may be designed such that the authentication data of the authentication object that approaches or touches other authentication positions will not be read. The display of more than one such guidance image can provide an unprecedented new authentication process. For example, the device can pose a question to the user and display several possible answers thereto at more than one authentication position on the screen. In this case, a more accurate authentication is possible by having previously registered a correct answer, which only the user know, in the authentication device. Alternatively, when the authentication device is installed in a gaming machine, the gaming machine may provide a bonus to a player who succeeds in authentication by selecting the correct authentication position.
The above-described authentication device according to the present invention preferably further comprises a data communications unit which performs wireless data communications with the authentication object after the authentication unit completes the authentication process. In that case, the data communication is performed after the authentication process, and accordingly, this prevents any illegal data communications from being performed with the authentication objects before the authentication process is completed.
The above-described authentication device according to the present invention is preferably installed in a gaming machine. Here, the gaming machine preferably further comprises a game control unit which controls a game in accordance with a predetermined game program. In that case, the display unit displays, in particular, images on the screen that are based on the progress of the game. This gaming machine is provided with the authentication position on the screen of the display unit (in particular, on the game screen) in which the authentication object is to approach or touch. Therefore, the authentication position can be provided on the surface in which the display unit is mounted, without limiting any further increase in the screen size of the display unit.
BRIEF DESCRIPTION OF THE DRAWINGSReferring now to the attached drawings which form a part of this original disclosure:
Selected embodiments of the present invention will now be explained with reference to the drawings. It will be apparent to those skilled in the art from this disclosure that the following descriptions of the embodiments of the present invention are provided for illustration only and not for the purpose of limiting the invention as defined by the appended claims and their equivalents.
Embodiment 1 Embodiment 1 of the present invention is a gaming machine, in particular, a video slot machine which is placed in a casino. First, the fundamental configuration of the slot machine will be explained (see
The monitor 11 is placed inside the slot machine 1. The monitor 11 is preferably a liquid crystal display, or alternatively may be a plasma display or another type of flat-panel display. However, the monitor 11 in Embodiment 1 must allow infrared rays to pass between the rear of the monitor 11 and the display screen of the monitor 11, as described below in greater detail. Five symbol display regions 11a are, in particular, included on the monitor 11. A plurality of symbols are aligned in a specific order and displayed in each symbol display region 11a. A touch panel 17 is further provided on the screen of the monitor 11. The touch panel 17 includes a transparent touch sensor, preferably an analog capacitive coupling touch sensor, or alternatively, may be an ultrasonic wave (surface elastic wave) touch sensor. Additionally, a credit display unit 11b, a BET display unit 11c, and an award display unit 11d are displayed on the screen of the monitor 11. The total number of credits belonging to the player (the money which the player inserted into the coin slot 5a or the bill slot 5b) is displayed on the credit display unit 11b. The amount that the player has bet is displayed on the BET display unit 11c. Here, the player operates the BET buttons 7a, 7b, and 7c to set the amount of the bet. The number of credits which the player has won as a result of the game is displayed on the award display region 11d. An inspection device (which authenticates the coins and the bills inserted by the player), a hopper (which stores a plurality of coins), a coin payout device (which uses the hopper to discharge a predetermined number of coins through the coin outlet 9a), a speaker, a main control unit, and a sub-control unit are further included inside the slot machine 1.
A reset switch 12 is provided on the side of the slot machine 1. There is a keyhole in this reset switch 12. The reset switch 12 can be activated by inserting a specific key into this keyhole. The specific keys are held by one or more casino workers, and accordingly players cannot operate the reset switch 12.
A card slot 13 and a display device 14 are provided on the top of the slot machine 1. A house card (a removable recording medium used in the casino) is inserted into the card slot 13. The house card is provided to each player. The house card stores identification data (player ID) of the player. A management server of the casino matches players' personal data (which players register at the reception desk or the like of the casino) to the respective player IDs. The amount of money that the player has spent on the games, and the points corresponding to the amount of money spent, are also recorded on the house card. In particular, a player can receive a bonus such as a free accommodation coupon based on the number of points the player has. The display device 14 displays the number of points the player has received. Moreover, the house card is used when the player uses the money previously deposited in the casino to play a game on the slot machine 1 (described below in greater detail).
The main control unit 20 includes a first CPU 21, a first input/output port 21a, a first ROM 22, a first RAM 23, a random number generating circuit 24, a first display control unit 25, a lighting control unit 26, a sound control unit 27, and a payout control unit 28 (see
The sub-control unit 30 includes a second CPU 31, a second ROM 32, a second RAM 33, a card reader 34, a second display control unit 35, a second input/output port 36, a third I/O port 37, and an authentication data input unit (an infrared ray irradiation unit 38 and a fingerprint sensor 39) (see
The authentication data input unit, that is, the infrared ray irradiation unit 38 and the fingerprint sensor 39, is placed on the rear side of the monitor 11, preferably at the lower right portion of the screen when seen by the player (see
The following explains each operation of the above-described units in accordance with the flow of a game performed in the slot machine 1 (see
The player operates the winning line selection buttons 8a, 8b, 8c, and the BET buttons 7a, 7b, and 7c, in order to enter selected winning lines and the amount to be bet (step S1). For example, 1-3 winning lines are selected, and 1-3 bet credits are selected. Here, the operational contents of each button are sent to the first CPU 21 of the main control unit 20 as operation signals. The first CPU 21 processes credit data recorded in the first RAM 23 in order to reduce the number of credits in the credit data by the credits represented by the operation signal (step S2). For example, when three winning lines and two bet credits per winning line are selected, the number of credits in the credit data recorded in the first RAM 23 are reduced by 6 (i.e., 2×3) credits.
Then, the first CPU 21 will accept an operation signal from the spin button 6a. In other words, the operation of the spin button 6a by the player will be allowed. When the player operates the spin button 6a, the first CPU 21 generates and sends a start signal to the first display control unit 25 and the random number generating circuit 24 (step S3). The first display control unit 25 starts a moving symbol display control in response to the start signal, and thereby continues to change the symbols displayed in each symbol display region 11a on the monitor 11 (step S4). The random number generating circuit 24 generates five random numbers in response to the start signal, and then sends these random numbers to the first CPU 21 in the order they are generated (step S5). Each random number is allocated to each symbol display region 11a displayed on the monitor 11. Each time a random number is received from the random number generating circuit 24, the first CPU 21 accesses stop position tables stored in the first ROM 22. Here, the stop position tables show the corresponding relationship between random numbers and the display patterns of the symbols, and preferably one table is prepared for each symbol display region 11a. The first CPU 21 retrieves from the stop position tables a display pattern of the symbols which corresponds to each random number for each symbol display region 11a. The retrieved display pattern of the symbols indicates the arrangement (the stop positions) of the symbols to be displayed in each symbol display region 11a at the end of the moving symbol display. The first CPU 21 further performs a lottery process based on the five random numbers sent from the random number generating circuit 24 (step S6). In other words, the first CPU 21 retrieves the combination of the random numbers from a winning determination table stored in the first ROM 22, and then determines whether or not the player wins an award based on the combination. Here, the awards provided to the player preferably include a right (bonus) to proceed to a special game (a bonus game such as an event, a free game, or a feature game), in addition to a predetermined number of credits. In that case, the winning determination table used for the special game is stored in the first ROM 22, in addition to the winning determination table used for a normal game. Furthermore, a different winning determination table may be prepared for each of the winning lines selected by using the winning line selection buttons 8a, 8b, and 8c.
After the lottery process (step S6), the first CPU 21 of the main control unit 20 controls the first display control unit 25 to stop the moving symbol display in each symbol display region 11a and display the symbols at their stop positions (step S7). After the symbols are displayed at the stop positions in each symbol display region 11a, the first CPU 21 outputs predetermined effect signals to the lighting control unit 26 and the sound control unit 27. The lighting control unit 26 controls each light emission unit included in the various lamps 10a, 10b, and lamp buttons (for example, the spin button 6a, the credit payout button 6b, the BET buttons 7a, 7b, 7c, and the winning line selection buttons 8a, 8b, and 8c), to blink in a pattern according to the received effect signal. The sound control unit 27 switches the sound effect coming out of the speaker 15 to the sound effect according to the received effect signal. When a payout of credits has been determined in the lottery process (step S6, S8, S9), the first CPU 21 then performs a payout process, and thereby adds credits to be awarded to the number of credits in the credit data recorded in the first RAM 23 (step S10). On the other hand, when the grant of a bonus is determined in the lottery process (step S6, S8, S9), the first CPU 21 switches from the usual control mode to the special control mode (an event or a bonus game) which corresponds to the bonus (step S11).
The slot machine 1 according to Embodiment 1 of the present invention converts credits spent on the games by the player to points, and then provides various services to the player depending on the number of points accumulated. A player who wants the chance to earn these services will register at the reception desk of the casino prior to playing a game on the slot machine 1. In this registration process, for example, the player will provide his/her personal data (such as the player's name and address) on a form, and then submits the form at the reception desk in order to receive a house card in which a player ID is recorded. The submitted personal data of the player is registered in the database of the management server 40 via a terminal.
A service which allows a player to use credit data that indicates the amount of money (credit) deposited in the casino for the game is provided in Embodiment 1 of the present invention. More specifically, the player deposits money at a specific location in the casino, such as the reception desk. The amount of money deposited is shown in the credit data, which is recorded in the database of the management server 40. The player's player ID is linked to the credit data. This makes games more enjoyable for the player, because the player can play games at the slot machine 1 without carrying money. Here, a sufficiently high level of security to protect the credit data registered in the management sever 40 essential in order to achieve such a service. Embodiment 1 of the present invention ensures this sufficiently high level of security as follows.
The following describes a method of using the credit data registered in the management server 40, which is a distinctive characteristic of the present invention (see
When the player ID is determined to be invalid in step S23, the second CPU 31 informs the first CPU 21 of the main control unit 20 of the results of this determination. The first CPU 21 then commands the first display control unit 25 to display an error message on the monitor 11 (step S31). On the other hand, in the sub-control unit 30, the second CPU 31 sends a card discharge signal to the card reader 34 in order to discharge the house card (step S32). When the player ID is determined to be valid in step S23, the second CPU 31 informs the first CPU 21 of the main control unit 20 of the results of the determination. The first CPU 21 then commands the first display control unit 25 to display a personal authentication screen on the monitor 11 as shown in
When the player touches the inside of the authentication frame of the image 11f with his/her right index finger, the touch panel 17 detects this act (step S25). The result of the detection is sent from the touch panel 17 through the first CPU 21 of the main control unit 20 to the second CPU 31 of the sub-control unit 30. The second CPU 31 then sends a command to the infrared ray irradiation unit 38 to irradiate infrared rays, and the infrared ray irradiation unit 38 emits infrared rays from its infrared ray irradiating surface. The infrared rays emitted from the infrared ray irradiation unit 38 penetrate the screen of the monitor 11 and the touch panel 17, and are then reflected by the right index finger of the player placed on the authentication position. The reflected light penetrates the screen of the monitor 11 and the touch panel 17, and is then detected by the fingerprint sensor 39. The fingerprint sensor 39 decodes the fingerprint pattern of the right index finger from the detected light, and then generates fingerprint pattern data, which is sent to the second CPU 31 (step S26).
The second CPU 31 performs a fingerprint authentication process to match the fingerprint pattern data received from the fingerprint sensor 39 with the fingerprint pattern data which matches the player ID received from the card reader 34 (step S27). More specifically, after having received the fingerprint pattern data from the fingerprint sensor 39, the second CPU 31 sends a request for fingerprint pattern data (which includes the player ID received from the card reader 34) through the third I/O port 37 to the management server 40. After receiving this request, the management server 40 reads the fingerprint pattern data which matches the player ID included in the request from the database, and then transmits the data to the sub-control unit 30 of the slot machine 1. The fingerprint pattern data received by the third I/O port 37 is sent to the second CPU 31, which matches the received fingerprint pattern data with the fingerprint pattern data received from the fingerprint sensor 39. This fingerprint authentication process determines whether or not the player is the person who has the authority to use the credit data which matches the player ID recorded in the house card that is inserted into the card reader 34 (in other words, whether or not the player is the person that requested registration of the credit data). Note that the management server 40 may perform the above-described fingerprint authentication process, instead of the control unit of the slot machine 1. In this case, the second CPU 31 sends the fingerprint pattern data received from the fingerprint sensor 39 to the management server 40, and then receives the results of the determination of the management server 40 as a response. When the fingerprint pattern data read from the player does not match the registered fingerprint pattern data in the above-described fingerprint authentication process, the second CPU 31 informs the first CPU 21 of the main control unit 20 of the authentication results (step S28). The first CPU 21 then commands the first display control unit 25 to display an error message on the monitor 11 (step S31). The second CPU 31 sends a card discharge signal to the card reader 34 to discharge the house card (step S32). When the fingerprint pattern data read from the player matches the registered fingerprint pattern data in the above-described fingerprint authentication process, the second CPU 31 performs an acquisition process which matches the credit data with the player ID received from the card leader 34 (step S28, S29). More specifically, the second CPU 31 sends a request for the credit data (which includes the player ID received from the card reader 34) to the management server 40 through the third I/O port 37. After receiving the request, the management device 40 reads the credit data which matches the player ID included in the request from the database, and then transmits the credit data to the sub-control unit 30 of the slot machine 1. The credit data received by the third I/O port 37 is sent to the second CPU 31, which then sends the credit data to the first CPU 21 of the main control unit 20. The first CPU 21 records the received credit data in the first RAM 23 (step S30). In this manner, the player's credit data can be used for the game on the slot machine 1.
In Embodiment 1 of the present invention, the points are provided to the player depending on the amount of money or the like which the player has spent on the game, and managed by the management server 40 as described above. In this case, the response to the request for the credit data includes point data which matches the player ID. Here, the point data preferably indicates the total points which has been provided to the player in all the games played by the player in the casino. When a player plays a game in the casino for the first time, the player's point data indicates “0”. When a player has previously played one or more games in the casino, the player's point data indicates the total points which the player has previously earned. The second CPU 31 of the sub-control unit 30 stores the point data received from the management server 40 in the second RAM 33 for a period of time. After that, the second CPU 31 outputs an instruction to the second display control unit 35 that is displayed in accordance with the point data. Thus, the second display control unit 35 controls the display device 14 so as to display character data that indicates the number of points available. On the other hand, every time the player performs a game in the slot machine 1, the first CPU 21 of the main control unit 20 outputs the credit consumption data (which indicates the number of credits that have been consumed) recorded in the first RAM 23 through the first I/O port 21a to the sub-control unit 30. The credit consumption data is input into the second CPU 31 through the second I/O port 36 of the sub-control unit 30. The second CPU 31 converts the credit consumption data to points, and then adds the points to the points in the point data stored in the second RAM 33. After the points are added, the point data can be displayed at any time by the display device 14. The second CPU 31 further outputs data which indicates the converted points to the player ID, as well as to the management server 40, through the third I/O port 37. The management server 40 retrieves the point data from the database which matches the received player ID, and adds the received points to the points in the retrieved point data. The player can use the points in the point data registered in the database of the management server 40 in exchange for services, depending on the total points the player has, at places in the casino such as the reception desk.
In Embodiment 1 of the present invention, the authentication data input unit (the infrared ray irradiation unit 38 and the fingerprint sensor 39) is located on the rear side of the monitor 11, and reads the fingerprint pattern of the right index finger of the player that is touching the screen of the monitor 11, through the screen of the monitor 11, as mentioned above. In particular, the authentication position which the player's right index finger (authentication object) is to touch exists on the screen of the monitor 11 (inside the authentication frame shown in
Embodiment 2 of the present invention is applied to a video slot machine that is similar to the slot machine described in Embodiment 1. Here, the slot machine according to Embodiment 2 of the present invention differs from the slot machine of Embodiment 1 in the way a player ID is read from a house card and the structure used to perform the same. The other basis structures and operations of the slot machine of Embodiment 2 are similar to those of Embodiment 1. Accordingly, the following will describe the portions of the slot machine of Embodiment 2 that are different than that of Embodiment 1.
The configuration of the main control unit of the slot machine 1 according to Embodiment 2 of the present invention is similar to the configuration of the main control unit according to the above-described Embodiment 1 shown in
When the player uses the registered credit data for the game in the slot machine 1, the player holds the house card over the card reading region in accordance with the guidance images displayed on the screen. Because the magnetic field generating unit 138 always generates the magnetic fields in the vicinity of the card reading region, the IC tag inside the house card receives electric power when the house card is held near the card reading region. By using the electric power, the communications circuit unit of the IC tag transmits the player ID stored in the storage unit from the antenna coil. The transmitted player ID is received by the card communications unit 139 on the rear of the monitor 11. The card communications unit 139 performs an ID authentication process to determine whether the received player ID is valid or not.
Preferably, the IC tag reader unit includes a detection unit. The detection unit is preferably an infrared ray sensor, which detects the house card when it is held near the card reading region. In this case, the magnetic field generating unit 138 may not always have to generate magnetic fields. For example, when the detection unit detects the approach of the house card to the card reading region, the result of the detection is sent to the second CPU 31 of the sub-control unit 30. The second CPU 31 then starts the magnetic field generating unit 138 to generate the magnetic fields for a predetermined period of time.
The second CPU 31 informs the first CPU 21 of the main control unit 20 of the results of the ID authentication process by the card communications unit 139. When the player ID received by the card communications unit 139 is determined to be invalid, the first CPU 21 controls the first display control unit 25 so as to display an error message on the screen of the monitor 11. When the player ID received by the card communications unit 139 is determined to be valid, the first CPU 21 controls the first display control unit 25 so as to display the personal authentication screen on the monitor 11, as shown in
As described above, in the slot machine according to Embodiment 2 of the present invention, the authentication data input unit (the magnetic field generating unit 138 and the card communications unit 139) is located on the rear side of the monitor 11, and reads the player ID through the screen of the monitor 11 from the house card held near the screen of the monitor 11. In particular, the authentication position (the card reading region) where the house card needs to be held is on the screen of the monitor 11. Accordingly, the authentication position is placed in a location that the player can easily access without increasing the screen size of the monitor 11.
When a non-contact IC tag is mounted in the house card as in Embodiment 2 of the present invention, credit data may be stored in the storage unit inside the non-contact IC tag. In this case, the card communications unit 139 receives the credit data from the IC tag of the house card by near field wireless communications, instead of the acquisition process of the credit data from the management server 40 according to Embodiment 1. More specifically, the second CPU 31 of the sub-control unit 30 transmits a request for the credit data through the card communications unit 139 to the IC tag of the house card. The IC tag then reads the credit data from the storage unit, and transmits the credit data from the antenna coil. The second CPU 31 receives the credit data through the card communications unit 139, and then sends the credit data to the first CPU 21 of the main control unit 20. The first CPU 21 records the received credit data in the first RAM 23, and then uses the credit data for the game in the slot machine 1. In such a configuration, the management server 40 does not have to manage the credit data.
Embodiment 3Embodiment 3 of the present invention is applied to a video slot machine, similar to Embodiment 1. Here, the slot machine according to Embodiment 3 of the present invention differs from the slot machine of Embodiment 1, in the way personal authentication is performed by using a fingerprint authentication process, and the structure used to perform the same. The other basic structures and operations of this slot machine are similar to those of Embodiment 1. Accordingly, the following will describe the portions of the slot machine of Embodiment 3 that differ from those of Embodiment 1.
When the player uses the credit data registered in the management server 40 for a game, the control unit of the slot machine of Embodiment 3 of the present invention performs the following control procedures (see
The first CPU 21 of the main control unit 20 controls the first display control unit 25 based on the received data which indicates the question and correct answer combination, so as to display the personal authentication screen on the screen of the monitor 11 shown in
The slot machine according to Embodiment 3 of the present invention displays the three choices of answers 11l on the screen of the monitor 11, and allows the player to select one of them, as described above. When the player's finger touches the authentication position corresponding to the correct answer (e.g., “MAX”, where the finger touches the inside of the answer frame corresponding to “MAX”), the fingerprint pattern is read. On the other hand, when the player's finger touches the other authentication position corresponding to another answer (that is, the inside of the answer frame corresponding to “JAKE” or “ROCKY”), the fingerprint pattern is not read. Thus, only the player who can select the correct answer will undergo fingerprint authentication. As a result, the security of personal data such as credit data is ensured at an even higher level, because the reliability of the player's authentication is higher than that of an authentication that is based only on a fingerprint authentication process as in Embodiment 1.
Instead of the above-described authentication process, for example, the following service may be offered: specific questions and choices 11l of answers are displayed on the screen of the monitor 11; the player is allowed to select one of the choices 11l by using his or her finger; and when the player touches the answer frame corresponding to the correct answer, the player wins a predetermined number of points. In this case, the first CPU 21 of the main control unit 20 determines whether or not the player has selected the correct answer, based on a result of detection of the touch panel 17. When the player has selected the correct answer, the first CPU 21 informs the second CPU 31 of the sub-control unit 30 of the result of the determination. The second CPU 31 then adds bonus points to be awarded to the player to the points in the point data stored in the second RAM 33.
Note that each of the above-described embodiments of the present invention is applied to a slot machine installed in a casino. However, the present invention is not limited to use in slot machines. In other words, the present invention is applicable to general electronic appliances equipped with both a monitor and an authentication device. In particular, the authentication position overlaps with the screen according to the present invention, which achieves both a further increase in screen size and a further simplification of the authentication process, while keeping the overall size of the appliance sufficiently small. Accordingly, the present invention is particularly advantageous when applied to portable electronic appliances, such as notebook computers and cellular phones.
