The rear holder 5h functions as a reflecting plate to reflect light emitted to the light guiding plate 5g from the cold cathode ray tubes 30a toward the liquid crystal display panel 5. The antistatic sheet 5 is made transparent and is adhered to the rear plane of the rear holder 5h by a double-sided tape, thereby the antistatic sheet 5i covers the openings formed in the rear holder 5h.

FIG. 5 is a block diagram showing a circuitry construction of a control circuit 40 for controlling game operation process in the slot machine 1 of the embodiment.

The control circuit 40 is mainly constructed from a microcomputer 41 and the microcomputer 41 is constructed from a main CPU 42 (Central Processing Unit) for conducting control operation according to a program preset beforehand, a ROM (Read-Only Memory) 43 as a storing device and a RAM (Random Access Memory) 44. In the ROM 43, control procedures for wholly controlling the gaming machine are stored as a sequence program and the RAM 44 is utilized as a temporary memory work area and the like when such program is executed.

To the main CPU 42, a clock pulse generator 45 for generating standard clock pulses and a frequency divider 46, a random number generator 47 for generating random numbers within a predetermined range and a sampling circuit 48 for sampling one random number generated by the random number generator 47, are connected. Further, an I/O port 49 to receive and output various signals between peripheral devices (actuators) mentioned later, is connected to the main CPU 42. And the ROM 43 has also memory areas to store a winning combination table which is referred when the winning combination is determined based on a symbol combination, other than the sequence program.

Here, the microcomputer 41, the random number generator 47 and the sampling circuit 48 constructs a lottery device to determine the winning combination by a lottery and selects the symbols which are stopped and displayed on the display windows 6 to 8 or the liquid crystal display panel 5d by a lottery and determines the winning combination based on the selected symbol combination. And the microcomputer 41 constructs a game medium storing device for storing the betted money inserted from the coin insertion slot 11 and the bill insertion portion 12 as data in the RAM 44.

As the main actuator the operation of which is controlled by a control signal from the microcomputer 41, there exist stepping motors 50 for rotating and driving the reels 2 to 4, various lamps 51, a LED display part 52, a hopper 53 for storing coins, the liquid crystal display panel 5d and a speaker 55. These are driven and controlled by a motor drive circuit 56,a lamp drive circuit 57, a LED drive circuit 58, a hopper drive circuit 59, an image control circuit 60 and a sound control circuit 61, respectively, These drive circuits 56 to 59 and the control circuits 60, 61 are connected to the main CPU 42 through the I/O port 49.

And as the main input signal generation device for generating input signals necessary for the main CPU 42 to produce control signals, there exist a start switch 9S for detecting operation of the start lever 9, the spin switch 13, the change switch 14, the cashout switch 15, the 1-BET switch 16, the MAX BET switch 17 and a coin sensor 11S to detect coins inserted in the coin insertion slot 11. Further, a reel position detection circuit 62 for detecting the rotation position of the reels 2 to 4 is provided.

And as the input signal generation device, there exist a coin detection part 53S for counting the number of coins paid out from the hopper 53, a payout completion signal generation circuit 63, the numerical keypad device 30 constructed from the numerical keypad image displayed on the liquid crystal display panel 5d and the predetermined area of the touch panel 5k corresponding to the numerical keypad image and a numerical keypad device detection circuit 64. The payout completion signal generation circuit 63 generates a signal to detect a coin payout completion when the coin count value corresponded to the coin number actually paid out and input from the coin detection part 53S reaches to the payout coin number data. And the numerical keypad device detection circuit 64 detects operation of the numerical keypad device 30, such operation being done by touching the touch panel 5k corresponding to numerical keys of the numerical keypad image displayed on the liquid crystal display panel 5d and outputs the detected operation signal to the main CPU 42. The above payout completion signal generation circuit 63 and the numerical keypad device detection circuit 64 are also connected to the main CPU 42 through the I/O port 49. Here, the main CPU 42 constructs a bet number recognition device to recognize the numerical value input from the numerical keypad device 30 as the bet number of the money betted.

In the above construction, before the game is conducted in the slot machine 1, the player at first inserts coins in the coin insertion slot 11 or inserts a bill in the bill insertion slot 12, thereby the betted money is stored in the slot machine 1. Next, the sum betted for the game is directed by the player among the betted money which is stored. This direction is done by conventional operation of the 1-BET switch 16 or the MAX-BET switch 17, or by operation of the numerical keypad device 30 constructed from the liquid crystal display panel 5d and the touch panel 5k.

On a game image displayed on the liquid crystal display panel 5d of the reel display window portion 5, as shown in FIG. 6, a character image 31, a bet number (BET) display part 32 and a payout (WIN) display part 33 are displayed. When the touch panel 5k corresponding to a periphery of the bet number display part 32 is touched, the numerical keypad image is displayed on the liquid crystal display panel 5d, thereby numerical value input operation is activated through the numerical keypad device 30 constructed from the numerical keypad image on the liquid crystal display panel 5d and the touch panel 5k. The numerical keypad device 30 is provided with numerical keys of “0” “9” and “00” and a clear key (CLEAR). Here, the numerical keys and the clear key are constructed from the numerical and clear key images included in the numerical keypad image displayed on the liquid crystal display panel 5d and the touch panel 5k. And the numerical value input by touching the touch panel 5k corresponding to the numerical key images is displayed in an input numerical value area 34 formed at an upper position of the numerical keypad image in the numerical keypad device 30. For example, the touch panel 5k corresponding to three numerical key images of “3”, “9”, “5” are pressed in this order, the number “395” is displayed in the input numerical value area 34. Thereafter, the numerical keypad image disappears at the timing that the player operates the start lever 9 or the spin switch 13 or the MAX BET switch 17 and the bet number is recognized as the numerical value “395” by the main CPU 42, thereby this bet number is displayed in the bet number display part 32. In the embodiment, the bet number from 1 to 1000 can be directed through the numerical keypad device 30. And in a case that the bet number is input by the numerical keys, if a false numerical value is input, such value can be corrected by pressing the touch panel 5k corresponding to the clear key image and again inputting the correct numerical value by touching the touch panel 5k corresponding to the numerical key images.

When the bet number is recognized, the main CPU 42 sets the sum calculated by multiplying the bet number with the unit sum corresponding to one bet as the betted money. And based on the operation of the start lever 9 or the spin switch 13 or the MAX BET switch 17 by the player, rotation process of the reels 2 to 4 is done and the slot machine game is started. And in a case that the symbol combination of the winning combination with payout is stopped and displayed along the pay line L, the payout corresponding to the betted money which is set by the main CPU 42 is given to the player. Thereby, the credit number is increased or coins are paid out to the coin tray 19.

According to the slot machine 1 of the embodiment, as mentioned, when the numerical value is input through the numerical keypad device 30 constructed from the numerical keypad image displayed on the liquid crystal display panel 5d and the touch panel 5k, such numerical value is recognized as the betted number by the main CPU 42 and the slot machine game is conducted after the betted money corresponding the recognized bet number is set. Thus, the player can voluntarily set the bet number without being limited to the bet number “1” allotted to the 1-BET switch 16 and the bet number “1000” allotted to the MAX BET switch 17, as in the conventional slot machine. Therefore, even in a case that the bet number is large, the player can quickly set the bet number without troublesome operation, for example, without pressing the 1-BET switch 16 395 times in order to conduct the game with 395 bets.

And in the embodiment, the numerical keypad image is displayed on the liquid crystal display panel 5d in the reel display window portion 5 which displays the game image of the slot machine 1, and the player can input the bet number by touching the touch panel 5k corresponding to each of the numerical key images constructing the numerical keypad device 30 in cooperation with the touch panel 5k. Therefore, the player can operate the numerical keypad device 30 while seeing the reel display window portion 5 and operability to determine the bet number can be raised.

Here, in the embodiment, although the bet number is determined by the numerical keypad device 30 every the unit game, the present invention is not limited to this. For example, it may be constructed so that the bet number input through the numerical keypad device 30 is used as the bet number over a plural times of games and such bet number is used for setting the betted money. That is to say, the bet number input in the present game by the player may be stored as the data in the RAM 44 and the like and it may be provided a repeat bet switch to determine the stored data in the RAM 44 as the bet number in the next games. In this case, in the next games, so long as the bet number is determined by the repeat bet switch without again inputting the bet number through the numerical keypad device 30, the stored data in the RAM 44 is continued to be used as the bet number. And when the bet number is again input through the numerical keypad device 30, the data stored in the RAM 44 may be displayed in the bet number display part 32.

According to the above construction, in a case that the constant bet number is used over a plural times of games, the player can omit the input operation of the bet number through the numerical keypad device 30 every the unit game, thereby operation in the game can be reduced. As a result, even if the player conducts games for a long time, the player can concentrate in games without feeling fatigue and improvement of motivation for games can be expected.

And it may be determined corresponding to a gaming state whether or not the bet number input through the numerical keypad device 30 by the player is used for setting the betted money. For example, it is supposed two gaming states, in which the expectation values of the payout paid out to the player in the unit game are different with each other, and it is supposed that the gaming state with lower expectation value is the first gaming state and the gaming state with high expectation value is the second gaming state. At that time, in one of the first gaming state and the second gaming state, the bet number input through the numerical keypad device 30 by the player is used and in the other gaming state thereof the bet number fixedly stored in the ROM 43 is used.

According to the above construction, there may be a case that the rate for getting coins in the specific gaming state may be controlled.

And according to the gaming state, it may be conceivable that a range of the bet number which the player can input through the numerical keypad device 30 is changed. For example, in the above first gaming state, the bet number may be selected within the range up to a predetermined first upper limit value (for example, the bet number is 1000) and in the above second gaming state, the bet number may be selected within the range up to a predetermined second upper limit value (for example, the bet number is 100) lower than the above first upper limit value. Further, the second upper limit value may be set higher than the first upper limit value. And a lower limit value of the bet number which the player can input may be changed according to the gaming state.

According to the above construction, there may be a case that the rate for getting coins in the specific gaming state may be controlled.

And in the above embodiment, although it is explained the case that operation of the numerical keypad device 30 is detected by the numerical keypad device detection circuit 64 and the detected value is input to the main CPU 42, thereby the bet number is determined, the present invention is not limited to this. For example, it may be conceivable that the function of the numerical keypad device detection circuit 64 is provided with the touch panel 5k and the value input through the numerical keypad device 30 is directly given to the main CPU 42 from the touch panel 5k. According to this construction, in the cabinet to which the touch panel 5k is installed as the standard, the slot machine having the same function as the above embodiment may be realized by only changing software thereof, without adding a new parts such as the numerical keypad device detection circuit 64.

Further, in the above embodiment, although dollar ($) and cent (¢) are utilized as the currency denomination displayed on the liquid crystal display panel 5d in the numerical keypad device 30 for inputting the bet number, the currency denomination is not limited to this. For example, the currency denomination displayed on the liquid crystal display panel 5d in the numerical keypad 30 may be pound and penny and the like, thereby the currency denomination may be changed and displayed corresponding to the area where the slot machine 1 is used.

And in the above embodiment, although the bet number is determined by directly inputting the numerical value through the numerical keypad device 30, determination method of the bet number is not limited to this. For example, a bet number selection panel may be displayed on the liquid crystal display panel 5d in the reel display window portion 5 in stead of the numerical keypad device 30, the bet number selection panel having a plurality of bet number selection parts in each of which the bet number is set beforehand by stages, and the bet number may be determined to the bet number in the bet number selection part to which the player touches.

In each of the above mentioned modifications, the effect similar to the above mentioned embodiment may be obtained.

In the above mentioned embodiment, although it is explained a case that the gaming machine of the present invention is applied to the slot machine, the present invention can be applied to the gaming machine in which game media are betted, similar to the above embodiment. For example, the present invention can be applied to a Japanese Pachi-slot gaming machine that rotation of the reels is stopped by operating the stop buttons, a poker gaming machine, a trump gaming machine, a mah-jong gaming machine and the like. Further, the present invention can be applied to a game program by which a home gaming machine can suspectedly execute the same operation as in each of the above gaming machines. In this case, as the recording medium to record the game program, various recording media such as CD-ROM, FD (Flexible Disk), flash memory card and the like can be utilized. If the present invention is applied to any of the above gaming machines, the same effect as that of the embodiment can be obtained.

Further, the numerical keypad image may be displayed on the liquid crystal display panel 5d every one game is terminated and when the player wants to change the bet number.

And the numerical keypad image may disappear when the touch panel 5k corresponding to the periphery of the bet number display part 32 is touched.

Further, in a case that the numerical keypad image includes an enter key image instead of the clear key image shown in FIG. 6, the numerical keypad image may disappear at the timing that the player touches the touch panel 5k corresponding to the enter key image.
