BACKGROUND OF THE INVENTION1. Field of the Invention
The present invention relates to a user interface for setting a wireless LAN function installed in an image forming apparatus.
2. Description of the Related Art
In recent years, there are an increasing number of users who use a so-called wireless LAN (Local Area Network) for performing communication among plural information terminals in a small area such as in a building and an ordinary house, storing data, and performing wireless communication with a server connected to an external network such as the Internet. In this wireless LAN, it is unnecessary to lay wiring for communication (wire) to the information terminals and, if a wireless function is given to the information terminals, it is possible to perform communication with wireless stations (access points) from free locations in a communication area.
Various settings are applied to these wireless stations such that a protocol for causing the wireless stations to perform communication is established. Setting of security is also important to prevent communication content from leaking to the outside and prevent intrusion from the outside. For example, JP-A-2005-176099 discloses a technique concerning a method of performing necessary setting in order to realize wireless connection.
As settings for a general wireless LAN, a large number of settings such as a setting of an SSID, a setting of an authentication system for security, and a type setting for a security network of a wireless system are performed. In a general personal computer, in most cases, setting is completed by a dealer when a user purchases the personal computer and, for example, setting is performed in accordance with an input guide by a program attached to a communication apparatus or the like. In this input guide, since setting is indicated in detail by pictures and sentences displayed on a screen, a general user can complete the setting if the user performs input as indicated and a setting screen proceeds even when the user does not have the knowledge what is to be inputted. Wrong input is often checked by the program.
Display screens provided in order to display certain limited information of a facsimile, a printer apparatus, and the like in the past have small screen sizes and are originally designed to be used for limited applications. Thus, unlike a screen of a display device of a personal computer, the display screens cannot display various kinds of information. Therefore, on a GUI screen for causing the user to perform setting for the wireless LAN, setting operation by selected display also used for other display items or simplified display is performed. In particular, it is not easy to set necessary setting items concerning respective authentication systems in a short time and properly by determining presence or absence of setting, selection of setting items, and the like unless the user has high degree of background knowledge in advance.
BRIEF SUMMARY OF THE INVENTIONAn embodiment according to the present invention provides a wireless LAN setting system mounted on an image forming apparatus with which a user can properly input necessary setting items even if the user does not have high degree of background knowledge.
An embodiment according to the present invention provides a wireless LAN setting system mounted on an image forming apparatus that performs network connection through a wireless LAN and used for performing wireless communication with plural terminals. The wireless LAN setting system has an existing setting check mode for checking, prior to performing wireless LAN setting, contents already set in the image forming apparatus, a network type selection mode for selecting a network used for the wireless communication, an SSID setting mode for establishing a predetermined protocol between the image forming apparatus and the plural terminals in the wireless communication, and a security mode for applying encoding to information to be communicated and performing wireless communication using a selected encryption system.
An embodiment of the present invention will be hereinafter explained in detail with reference to the drawings.
A system configuration according to this embodiment is constituted by an image forming unit 1 that forms images, characters, and the like on a recording medium such as recording paper, a communication input and output unit 3 connected to a network (including a telephone line and an optical cable line) 2, a storing unit 4 that stores image data, various kinds of setting information, and programs for operations and control, an input unit 5 that inputs a setting registration and an indication by a user, a display unit 6 that displays setting items and processing states, a control unit 7 that controls the entire system, a transmitting and receiving unit 8 for performing wireless communication or optical communication, a wireless access point 9 such as a wireless router connected to the transmitting and receiving unit 8 and set on the outside, and plural terminals 10a to 10c that the user uses.
The image forming unit 1 is constituted by an image scanning unit 11 that optically scans photographs, pictures, characters, and the like formed on a paper surface and the like, an image-data input unit 12 that captures image data inputted from the outside or image data scanned by the image scanning unit 11, an image forming unit 14 that includes a laser unit 13 for irradiating a laser beam on a not-shown photoconductive drum and forms (records) an image on recording paper, a conveying mechanism 15 that conveys the recording paper, a paper feeding unit 16 that stores unrecorded recording paper and feeds the paper to the conveying mechanism 15, and a storing unit (a sorter) 17 that stores recording paper having an image recorded thereon.
The storing unit 4 is constituted by, for example, a volatile memory such as a RAM and a nonvolatile memory such as a ROM and has a setting program for performing wireless LAN setting stored therein. Setting screen information displayed on the display unit 6 during setting is also included in this setting program. Besides, a storing unit may be constituted by a hard disk, a flash memory, and the like. As plural terminals used by the user, for example, personal computers or peripheral apparatuses such as MFP apparatuses are assumed. It goes without saying that it is possible to apply this embodiment to wireless communication among the MFP apparatuses.
In this embodiment, an example by wireless communication performed by using the wireless access point 9 is explained. As other communication means, it is also possible to use optical communication depending on an ambient environment in which the wireless access point 9 is set.
Setting operation in the wireless LAN setting system according to this embodiment is explained with reference to a flowchart shown in
First, a setting screen for an administrator shown in
In this wireless LAN setting start screen, the “WIRELESS SETTING” button and the “SETTING CHECK” button are displayed. When the user checks contents presently set (setting items and setting states) (step 2), the user touches the “SETTING CHECK” button (YES). On the other hand, when the user performs new setting or setting change (NO), the user touches the “SETTING CHECK” button.
When the user selects the “SETTING CHECK” button, the wireless LAN setting system enters an existing setting check mode (step S3) in which setting content lists shown in
When the user touches the “WIRELESS SETTINGS” button, a setting screen [Guide Indication: Perform a Wireless LAN Setting] for confirmation of use of the wireless LAN shown in
When the user touches “ON”, the use of the wireless LAN is selected. When the user touches “OFF”, the nonuse of the wireless LAN is selected. The selection of use and nonuse is provided for the purpose of stopping, when the wireless LAN is used, the wireless LAN if, for example, other apparatuses are adversely affected by wireless transmission. Therefore, the selection is used when, for example, the use of the wireless LAN is temporarily stopped. When the user touches “OFF”, a section of “NEXT” on the lower right of the screen is dimly displayed. Thereafter, after performing predetermined wireless LAN stop processing, the wireless LAN setting system shifts to, for example, a setting confirmation screen [Guide Indication: Please confirm the wireless setting] for the wireless LAN in
When the user touches “ON”, “NEXT” is displayed on the lower right of the screen. When the user touches this “NEXT” button, a network type selection screen [Guide Indication: Select Network type and Channel” shown in
When the user touches the “AUTO” button in the “CHANNEL” display, a channel of an AD HOC terminal already present is selected. During this setting of “AUTO”, operation of the “Channel” setting button is not accepted. Even when a channel is selected once, a setting to that point is released by touching a “CANCEL” button and the screen can be returned to the original state. When this setting of a network type is completed, the user touches the “NEXT” button and the wireless LAN setting system shifts to the next SSID (Service Set ID) setting mode (step S6). The SSID also includes an ESSID for extending a network identifier.
In this embodiment, six function modes, i.e., “WPA and WPA2”, “WPAPSK, WPAPSK2, and (IEEE)802.1X”, and “WEP” are displayed as encryption systems that can be used in the security mode. A mode is selected out of these function modes (step S9). In an example explained here, the respective modes are classified into three groups. In the mode selection, at least one mode is selected.
In this mode selection, when “WEP” is selected, a WEP encryption screen shown in
Next, when the WEP encryption setting is finished, the wireless LAN setting system determines whether a network type already set is “INFRASTRUCTURE” or “AD HOC” (step S11). When the type is set as “AD HOC” in this determination, a transmission power setting screen shown in
When any one of the function modes “WPA and WPA2” shown in
Moreover, when any one of the function modes “WPAPSK, WPAPSK2, and 802.1X” shown in
After the input of the user name, when the user touches the “NEXT” button, a user certificate setting screen [Guide Indication: Input the user certificate file name and password] shown in
When the user touches the “PEAP” button in the authentication system in step S15, an EAP account information input screen [Guide Indication: Input EAP account information] shown in
Next, when the user touches the “NEXT” button, a server authentication information input screen [Guide Indication: Input the authentication sever name] shown in
Next, when the user touches the “NEXT” button in
Next, when the user touches the “NEXT” button in
Next, the wireless LAN setting system displays a wireless setting confirmation screen [Guide Indication: Please set TRANSMIT POWER and TRANSMIT RATE] shown in
In the end screen shown in
As described above, the setting for the wireless LAN mounted on the MFP apparatus in the past targets users (administrators) having professional knowledge. Thus, a situation occurs in which, for a user who does not grasp setting contents, it is difficult to determine whether selection and setting of setting items are essential or it is impossible to set setting items. Even if the setting is completed, when wrong setting is made, a situation occurs in which it is impossible to find out which part of the setting is the wrong setting.
On the other hand, in the embodiment of the present invention, since the wireless LAN setting system has the mode for first checking, before setting, existing setting contents (setting items and setting states) presently set, it is possible to determine whether the setting is necessary. Since the guide indications are attached in necessary parts in the respective setting screens, even a user (an administrator) who does not have professional knowledge can perform proper determination and correctly perform setting operation. The guide indications in this embodiment are only examples. It is also easy to represent the guide indications more in detail or more simply.
Setting procedures for the wireless LAN according to this embodiment of the present invention are formed in order of network selection security setting and security designation. Thus, it is possible to skip or omit the procedures by selecting presence or absence of setting. Therefore, it is possible to complete the setting without performing useless scroll and designation operation of the setting screens.
During setting, it is possible to prevent setting mistakes due to misoperation by dimly displaying buttons unnecessary to be operated on a screen to disallow the user to select the buttons.
As explained above, according to this embodiment, the user can easily and properly perform setting in accordance with the procedures by the program in which the setting items of the wireless LAN are created in advance even if the user does not have high degree of background knowledge.
