Description

The present invention relates to an information processing device, a printing device, and a control method and program for them.

Communication devices such as smartphones, tablet PCs, and printers are equipped with wireless LAN functions. In wireless LAN functions, a direct wireless communication mode is known in which multiple communication devices are connected directly without going through an access point.

Patent document 1 describes a configuration in which a printing device and a mobile terminal directly communicate wirelessly using an access point mode, which is an example of a direct wireless communication mode.

When using the direct wireless communication mode with a communication device, the user must instruct the communication device to start operation in the direct wireless communication mode. For example, a "start button" for starting operation in the direct wireless communication mode is displayed on the communication device, and when the user presses this "start button," the communication device starts operation in the direct wireless communication mode.

Some communication devices are also equipped with a user authentication function. In this case, user authentication is performed, for example, by the user holding an IC card over an IC card reader provided in the communication device, or by the user entering a user ID and password into the communication device. If the user authentication is successful, the user can log in to the communication device, and once logged in, the user can use the functions provided by the communication device.

JP 2017-98916 A

In the case of conventional communication devices, after a user logs in to the communication device, the communication device starts operating in the direct wireless communication mode. In other words, the user can only use the direct wireless communication mode when he or she logs in to the communication device, and in order to do so, the user must be authenticated in advance. Therefore, a user who does not have an IC card, user ID, or password for authentication, such as a user who visits from outside the company, cannot log in to a printing device within the company. This causes an issue in that data stored on the user's mobile terminal cannot be printed using a printing device within the company.

The purpose of the present invention is to solve the problems of the conventional technology.

The object of the present invention is to provide an information technology that allows a user who has not been authenticated by an information processing device having an authentication function to use the functions of that information processing device.

In order to achieve the above object, an information processing device according to one aspect of the present invention has the following configuration.
An information processing device having a wireless communication function,
an operation unit that accepts user operations;
a display control unit that causes a display for logging in to the information processing device to be displayed on the operation unit;
the display control means causes the operation unit to display a screen on which the wireless communication function can be instructed after the user authenticated based on the user information input via the display for logging in logs in to the information processing device;
When a user is not logged in to the information processing device , a display for logging in is displayed on the information processing device, and a setting screen for establishing wireless communication using the wireless communication function is displayed on the operation unit by accepting an operation of a specific button without accepting the login on the operation unit;
The setting screen includes an instruction section for instructing to cancel printing.

The present invention has the advantage that even a user who has not been authenticated by an information processing device having an authentication function can use the functions of that information processing device.

Other features and advantages of the present invention will become apparent from the following description taken in conjunction with the accompanying drawings, in which the same or similar components are designated by the same reference numerals.

[Embodiment 1]
FIG. 1 is a diagram illustrating an overview of a communication system according to a first embodiment of the present invention.

This communication system includes a printing device 100, which is an example of an information processing device according to the present invention, and a mobile terminal 101. The printing device 100 has a wireless LAN function, which has two types of wireless communication modes: infrastructure mode and access point mode. The infrastructure mode is a wireless communication mode in which the printing device 100 wirelessly connects to a relay device such as an access point (not shown) and communicates with devices on a network such as a PC (personal computer). On the other hand, the access point mode is a wireless communication mode in which the printing device 100 itself acts as an access point by activating a software access point in the printing device 100.

A mobile terminal 101 such as a smartphone wirelessly connects to a printing device 100 operating in access point mode and transmits print data for printing electronic files such as photographs to the printing device 100. The access point mode allows wireless communication to be established directly between the printing device 100 and the mobile terminal 101 without going through an intermediate device such as an access point. The access point mode is an example of a direct wireless communication mode in which the printing device 100 and the mobile terminal 101 directly establish wireless communication.

In addition, instead of the access point mode, other wireless communication methods such as Wi-Fi Direct (registered trademark) may be applied to this embodiment. In this embodiment, a communication method for directly establishing wireless communication, such as the access point mode or Wi-Fi Direct (registered trademark), is described as direct wireless. In addition, the printing device 100 has a user authentication function, which will be described in detail later.

Figure 2 is a block diagram illustrating the hardware configuration of the printing device 100 according to the first embodiment.

The CPU 201 loads the control program stored in the ROM 202 into the RAM 203 and controls the operation of the printing device 100 by executing the loaded program. The ROM 202 stores the control program and various data. The RAM 203 is used as a temporary storage area such as the main memory and work area of the CPU 201. The HDD (hard disk drive) 204 is a non-volatile storage medium that stores various data, and may be a non-volatile memory other than an HDD. In addition, in the printing device 100 according to the first embodiment, one CPU 201 executes the processing shown in the flowchart described below, but other configurations are also possible. For example, multiple CPUs may cooperate to execute the processing shown in the flowchart described below. In addition, part of the processing in the flowchart described below may be executed using a hardware circuit such as an ASIC.

The wireless LAN I/F (interface) 205 executes wireless LAN communication between the mobile terminal 101 and external devices such as an access point. The wireless LAN communication executed by the wireless LAN I/F 205 is wireless communication such as IEEE802.11a/b/g/n/ac. The wireless LAN I/F 205 can operate in infrastructure mode and access point mode. The wireless LAN I/F 205 selects and operates in either infrastructure mode or access point mode according to the device settings set in advance by the user.

The network I/F 210 connects to a wired LAN via a LAN cable. The network I/F 210 can communicate with an external device (e.g., a PC) on the wired LAN. The printer 206 is a printer engine that prints an image on a sheet based on print data received via the wireless LAN I/F 205 or the network I/F 210. The scanner 207 reads an image of an original document and generates image data corresponding to the image. The image data generated by the scanner 207 is printed by the printer 206 or stored in the HDD 204. The operation unit 208 includes a display unit with a touch panel function, a keyboard, etc., and displays various operation screens on the display unit. A user can input instructions and information to the printing device 100 via the operation unit 208. The IC card reader 209 reads user information stored in an IC card. In the first embodiment, an IC card owned by a user stores the user's user ID and password. The printing device 100 then performs user authentication based on the user information read from the IC card by the IC card reader 209.

Figure 3 is a top view of the operation unit 208 of the printing device 100 according to the first embodiment.

The display unit 301 has a touch panel function and displays various operation screens. The home button 302 is a button for instructing the user to return to the home screen, which is the basis for all operations. The logout button 303 is a button for the user to log out when operations are completed. The back button 304 is a button for instructing the user to return from the currently displayed screen to the previous screen. The clear button 305 is a button for canceling input letters and numbers. The numeric keypad 306 is a button for inputting numbers and letters.

Next, we will explain the operation screen provided by the printing device 100 and the operation procedure when a user uses direct wireless.

Figures 4 and 5 (A) are diagrams showing example screens displayed on the display unit of the operation unit 208 of the printing device 100 according to the first embodiment.

Figure 4 (A) shows the login screen. This login screen is displayed when the printing device 100 has finished booting up. Here, the user can authenticate themselves by holding their own IC card over the IC card reader 209.

Figure 5 (B) shows an example of a user management table stored in, for example, HDD 204 of the printing device 100.

This user management table holds information for managing user information (user name, user ID, password) of users who are permitted to log in to the printing device 100. Therefore, users registered in this user management table can log in to the printing device 100.

When a user holds his/her IC card over the IC card reader 209, the IC card reader 209 reads user information (user ID and password) from the IC card. The CPU 201 then determines whether or not the user information read from the IC card by the IC card reader 209 is registered in the user management table. If the user information read from the IC card is registered in the user management table, authentication is successful, and the display on the operation unit 208 transitions to the menu screen of FIG. 4(B). A user who is thus successfully authenticated is logged into the printing device 100 and can use the functions of the printing device 100. On the other hand, if the user information read from the IC card is not registered in the user management table, authentication fails, the operation unit 208 notifies the user that authentication was not successful, and the menu screen is not displayed.

In the first embodiment, the user may input a user ID and a password via the operation unit 208 into the input fields 401 and 402 of the login screen in FIG. 4A, respectively, without using the IC card reader 209. When the user inputs a user ID and a password into the input fields 401 and 402 and presses the login button 403, the printing device 100 executes user authentication. Also, instead of the printing device 100 having a user management table, an external authentication server may have the table. If the authentication server has this user management table, the printing device 100 transmits the user information input from the IC card reader 209 or the operation unit 208 to the authentication server. Then, the printing device 100 executes user authentication by receiving the result of the authentication process by the authentication server (authentication successful or authentication failed) from the authentication server.

The menu screen in FIG. 4(B) displays buttons that allow the user to use the functions provided by the printing device 100. The copy button 411 is a button that allows the user to use the copy function. When the user presses this copy button 411, the operation unit 208 displays a copy screen (not shown).

The print cancel button 412 is a button that allows the user to cancel printing (a function that causes the printer 206 to interrupt printing and discard the print data). When the user presses the print cancel button 412, the operation unit 208 displays a print cancel screen (not shown).

The direct wireless connection button 413 is a button that allows the user to use direct wireless communication. When the user wants to use direct wireless communication, the user first presses the direct wireless connection button 413.

The setting button 414 is a button that allows the user to configure device settings for the printing device 100. When the user presses the setting button 414, the operation unit 208 displays various setting screens according to the user's operation.

Figure 4 (C) shows the setting screen for direct wireless printing. This screen is one of the setting screens that is displayed when the setting button 414 is pressed on the menu screen in Figure 4 (B). The items that can be set on this setting screen are explained in detail below.

The direct wireless printing setting screen is a screen that can be accessed by a user with special authority, such as a system administrator. Item 421 is a setting for setting permission to use printing by direct wireless communication when the user is not logged in. The registration button 422 is a button for reflecting the settings of this direct wireless printing setting screen in the printing device 100. When the system administrator presses the registration button 422, the contents set in this direct wireless printing setting screen are stored in the HDD 204, and the settings in this setting screen are reflected in the printing device 100. If the user selects "Do not allow" 423 on the direct wireless printing setting screen and presses the registration button 422, printing by direct wireless communication can be used only when the user logs in to the printing device 100 through user authentication. In other words, if "Do not allow" 423 is set on this direct wireless printing setting screen, the menu screen of FIG. 4(B) is displayed after login authentication is performed on the login screen of FIG. 4(A). In this case, since the user has already logged in, all functions are displayed and selectable on the menu screen of FIG. 4(B).

On the other hand, if the user selects "Allow" 424 on this direct wireless printing setting screen and presses the registration button 422, printing via direct wireless communication is made available through user authentication even if the user is not logged in. If "Allow" 424 is set on the direct wireless printing setting screen, pressing the home button 302 in FIG. 3 while the login screen in FIG. 4(A) is displayed will display the menu screen in FIG. 5(A).

When the menu screen in FIG. 5(A) is displayed, the user is not logged in, so only the direct wireless connection button 501 and the print cancel button 502 are selectable on this menu screen, limiting the functions of the printing device 100 that can be used.

Note that, while the login screen of FIG. 4(A) is displayed, pressing the home button 302 displays the menu screen of FIG. 5(A). However, this menu screen may also be displayed when another button, such as the logout button 303 of FIG. 3, is pressed.

When the user presses the direct wireless connection button 413 or 501 on the screen of FIG. 4 (B) or FIG. 5 (A), the operation unit 208 displays the wireless connection screen of FIG. 6 (A).

Figure 6 shows an example of a direct wireless connection screen displayed on the operation unit 208 of the printing device 100 according to the first embodiment.

The wireless connection screen in FIG. 6A displays a start button 601. This start button 601 is a button that the user uses to instruct the printing device 100 to start the direct wireless communication operation. When the operation unit 208 displays this wireless connection screen, the printing device 100 has not started the direct wireless operation. Therefore, even if the mobile terminal 101 searches for surrounding access points, it cannot find the printing device 100, and a wireless connection cannot be established between the mobile terminal 101 and the printing device 100. In order to establish a wireless connection between the mobile terminal 101 and the printing device 100, the user must press the start button 601 to cause the printing device 100 to start the direct wireless communication operation. When the user presses the start button 601, the printing device 100 starts the direct wireless communication operation. Then, the operation unit 208 displays the wireless connection screen in FIG. 6B.

When the printing device 100 operates in direct wireless mode, the printing device 100 generates an SSID and a connection key (e.g., a WEP key). The SSID and connection key generated by the printing device 100 are displayed in area 611 of the wireless connection screen in FIG. 6B. After checking the contents displayed in this area 611, the user searches for surrounding access points using his/her mobile terminal 101 and selects the access point with the SSID displayed in this area 611 from the list of search results. Then, the user inputs the connection key displayed in this area 611 into the mobile terminal 101, and a direct wireless connection is established between the printing device 100 and the mobile terminal 101. After the mobile terminal 101 is thus wirelessly connected to the printing device 100 using the direct wireless communication function, the user selects data to be printed on the mobile terminal 101. Then, when the user inputs a print command on the mobile terminal 101, the mobile terminal 101 uses the wireless communication function by direct wireless to transmit print data for printing the data selected by the user to the printing device 100. The printing device 100 receives this print data and executes the print process based on the received print data.

On the other hand, when the printing device 100 starts the direct wireless communication operation, the printing device 100 goes into a standby state to receive a request to establish a wireless connection from an external device such as the mobile terminal 101. When the printing device 100 starts the direct wireless communication operation, the mobile terminal 101 can find the printing device 100 when searching for surrounding access points. Then, when the printing device 100 receives a request to establish a wireless connection from an external device, it establishes a wireless connection with the external device by direct wireless communication. After this wireless connection is established, actual data communication (for example, transmission of print data from the mobile terminal 101 to the printing device 100) is performed between the printing device 100 and the external device.

The wireless connection screen in FIG. 6(B) displays a stop button 612. This stop button 612 is a button that allows the user to issue a stop instruction to stop the operation of direct wireless communication. The user presses the stop button 612 when he or she wants to stop the operation of direct wireless communication of the printing device 100. When the user presses the stop button 612, the printing device 100 stops the operation of direct wireless communication. In addition, in order to prevent the printing device 100 from remaining in operation of direct wireless communication, the wireless connection screen in FIG. 6(B) is displayed before switching the display to the login screen in FIG. 4(A). Then, only when the user presses the stop button 612 on the wireless connection screen in FIG. 6(B) and the printing device 100 stops the operation of direct wireless communication, does the screen transition to the login screen in FIG. 4(A).

Next, the process executed by the printing device 100 when a user uses direct wireless without logging in to the printing device 100 will be described with reference to the flowchart in FIG. 7.

Figure 7 is a flowchart explaining the processing executed by the printing device 100 according to the first embodiment. The processing of each step shown in this flowchart is achieved by the CPU 201 expanding a control program stored in a memory such as the ROM 202 into the RAM 203 and executing it. The printing device 100 may be configured so that at least some of the steps in the flowchart of Figure 7 are executed by the CPU 201, and the remaining steps are executed by another CPU (not shown) different from the CPU 201.

First, in S701, the CPU 201 causes the operation unit 208 to display the login screen shown in FIG. 4A. Here, the IC card reader 209 reads user information from the IC card, or the user enters a user ID and password in the input fields 401 and 402 of the login screen and presses the login button 403, and the process proceeds to S702, where user authentication is performed. In S702, the CPU 201 determines whether or not the user is permitted to log in based on the entered user information. This determination is made by checking whether or not the user information is registered in the above-mentioned user management table. Here, if the user information is registered in the user management table (determined as authentication successful), the process proceeds to S703. On the other hand, if the user information is not registered in the user management table (determined as authentication failed), the process proceeds to S705.

In S703, the CPU 201 displays the menu screen of FIG. 4B on the operation unit 208, and permits the user to use all functions. In S704, the CPU 201 performs various operations to execute the functions specified on the menu screen, and executes S704 and S705 until it determines in S705 that a logout operation has been performed. When the logout operation has been performed in this manner, the process returns to S701 and the login screen is displayed. Note that the various operations in S704 are not directly related to the present invention, and therefore a detailed description thereof will be omitted.

On the other hand, if the user authentication has not been performed in S702, the process proceeds to S705, where the CPU 201 determines whether a specific button on the operation unit 208 has been pressed. The specific button here is the home button 302 as described above, but may be the logout button 303 or another button. If the specific button has not been pressed, the process proceeds to S701, but if it is determined that the specific button has been pressed, the process proceeds to S707. In S707, the CPU 201 determines whether or not permission to use direct wireless printing is set when not logged in on the setting screen of FIG. 4C. This determination is made by referring to the information on the HDD 204 that holds the items set on the setting screen of FIG. 4C. Here, if "Do not allow" 423 has been selected on the setting screen, the process returns to S701 and displays the login screen. On the other hand, if "Allow" 424 has been selected on the setting screen, the process proceeds to S708, where the CPU 201 performs display control to display the menu screen shown in FIG. 5A, and then proceeds to S709. In S708, since the user is not logged in, only the direct wireless connection button 501 and the print cancel button 502 can be selected. Note that in S708, if the print cancel button 502 is pressed on the menu screen in FIG. 5A, the printing process of the print data sent using direct wireless communication is canceled, but a detailed description of this will be omitted.

In S709, the CPU 201 determines whether the direct wireless connection button 501 is selected on the menu screen of FIG. 5A and the start button 601 is pressed on the wireless connection screen of FIG. 6A to instruct the start of a direct wireless connection. If the CPU 201 determines in S709 that the start of a direct wireless connection is instructed, the process proceeds to S710, but if not, the process proceeds to S708. In S710, the CPU 201 starts wireless communication operation in the access point mode. Specifically, when the start button 601 is pressed, the CPU 201 causes the operation unit 208 to display the direct wireless connection screen of FIG. 6B. Here, the user of the mobile terminal 101 inputs the connection key displayed in the area 611 of this wireless connection screen into the mobile terminal 101, and a direct wireless connection is established between the printing device 100 and the mobile terminal 101. Then, the user of the mobile terminal 101 uses the wireless communication function by direct wireless communication to transmit print data for printing data selected by the user to the printing device 100. The printing device 100 receives this print data and executes print processing based on the print data. Then, the process proceeds to S711, where the CPU 201 determines whether the stop button 612 on the wireless connection screen in FIG. 6B has been pressed, and proceeds to S712 if it is determined that the stop button 612 has been pressed. In S712, the CPU 201 stops the direct wireless communication operation, returns to S701, and displays the login screen.

In addition, in S710, before switching the display to the login screen in FIG. 4(A), the wireless connection screen in FIG. 6(B) is displayed. This is to prevent the printing device 100 from remaining in operation in direct wireless communication.

As described above, according to the first embodiment, even if a user is not authenticated on the printing device, the printing device can be switched to the direct wireless communication mode by performing a specific operation on the printing device. This makes it possible to send print data from the terminal of an unauthenticated user to the printing device via direct wireless communication and have the data printed.

[Embodiment 2]
In the above-described first embodiment, an example has been described in which the printing device can be used by switching to the direct wireless communication mode by performing a printing device-specific operation without the user logging in to the printing device.

In contrast, in the second embodiment, an example is described in which, when a specific button on the operation unit of the printing device is pressed, an authentication screen for direct wireless communication is displayed, and only when this authentication is performed, the printing device transitions to the direct wireless communication mode. Note that the communication system and hardware configuration of the printing device according to the second embodiment are similar to those of the first embodiment described above, and therefore a description thereof is omitted.

Figure 8 shows an example of a direct wireless setting screen displayed on the operation unit 208 of the printing device 100 according to the second embodiment.

The following describes in detail the items that can be set on the Direct Wireless Settings screen in Figure 8 (A).

This direct wireless setting screen is a screen that can be accessed by a user with special authority such as a system administrator. Item 801 is a setting for whether or not to perform authentication for direct wireless communication when using printing via direct wireless communication when not logged in. The registration button 803 is a button for reflecting the settings on this direct wireless setting screen in the printing device 100. When the system administrator presses the registration button 803, the contents set on this direct wireless setting screen are stored in the HDD 204 and reflected in the printing device 100. When "Use" 804 is selected in item 801, use of printing via direct wireless communication is permitted only when authentication for direct wireless communication is successful and the user logs in. Therefore, when "Use" 804 is selected, it is necessary to set a password 802 for authentication of direct wireless communication. When "Use" 804 is selected, the menu screen of FIG. 5 (A) is displayed only when the user is successfully authenticated on the login screen of FIG. 8 (B) and logs in.

On the other hand, if "Do not use" 805 is selected in item 801, the menu screen in FIG. 5 (A) is displayed without displaying authentication for direct wireless communication.

Figure 9 is a flowchart explaining the processing executed by the printing device 100 according to the second embodiment. The processing of each step shown in this flowchart is achieved by the CPU 201 expanding a control program stored in a memory such as the ROM 202 into the RAM 203 and executing it. The printing device 100 may be configured so that at least some of the steps in the flowchart of Figure 9 are executed by the CPU 201, and the remaining steps are executed by another CPU (not shown) different from the CPU 201. In Figure 9, the same processing steps as those in the flowchart of Figure 7 described above are indicated by the same reference numbers, and their description will be omitted.

In S707 of FIG. 9, if permission to use printing via direct wireless communication is set, the process proceeds to S901. In S901, the CPU 201 determines whether or not the direct wireless communication setting screen in FIG. 8A is set to perform authentication of direct wireless communication based on information from the HDD 204. If "Do not use" 805 is selected here, that is, if authentication of direct wireless communication is not set to be performed, the process proceeds to S708, and the menu screen in FIG. 5A is displayed, as in the first embodiment described above.

On the other hand, in S901, if the CPU 201 has selected "Use" 804, i.e., if authentication of direct wireless communication is set to be performed, the process proceeds to S902, where the CPU 201 displays the login screen shown in FIG. 8(B) on the operation unit 208. If the user enters a password in the input field 811 and presses the login button 812, the process proceeds to S903, where the CPU 201 compares the password 802 set on the setting screen in FIG. 8(A) with the password entered in the input field 811 on the login screen. If these match, it is determined that authentication of direct wireless communication has been successful and the process proceeds to S708. On the other hand, if they do not match, it is determined that authentication has failed and the process proceeds to S902, where the login screen of FIG. 8(B) is redisplayed.

As described above, according to the second embodiment, in addition to the effects of the first embodiment described above, even a user who is not logged in can switch the printing device to the direct wireless communication mode if the user authentication for wireless communication is successful. This makes it possible to send print data from the terminal of an unauthenticated user to the printing device via direct wireless communication and have the data printed.
