[0016] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a diagram illustrating an example of the overall configuration of an information processing system 1. As shown in FIG. As illustrated in FIG. 1, the information processing system 1 includes a computer terminal 2, a scanner 4, and a WiFi router 6, and the computer terminal 2 is wirelessly connected to the WiFi router 6. The computer terminal 2 is a computer terminal operated by a user, and performs setting operations for the scanner 4. For example, the computer terminal 2 is a mobile terminal such as a smartphone or a tablet terminal, or a personal computer. The scanner 4 is an image reading device that optically reads an image from a document. The scanner 4 functions as an access point (parent device) in a wireless network such as WiFi (Wireless Fidelity) and as a child device, and can be directly connected wirelessly to the computer terminal 2 (direct connection) or can be connected to the computer terminal 2 via a WiFi router 6. The scanner 4 is an example of a peripheral device according to the present invention. The WiFi router 6 is an access point in a wireless network. The WiFi router 6 enables wireless connection from the computer terminal 2 based on, for example, wireless connection information. The wireless connection information is information for enabling wireless connection, and is, for example, a set of an SSID (Service Set Identifier) ​​and a password.

[0017] In the above configuration, when connecting and using peripheral devices such as a scanner or camera via a wireless network with a computer terminal 2 (such as a mobile terminal), it is generally necessary to set up the wireless connection. There are generally two types of connection methods. One is a "direct connection," in which a peripheral device such as a scanner 4 acts as an access point (AP), and the computer terminal 2 connects by joining that network. The other is an "AP connection," in which the peripheral device (scanner 4) and computer terminal 2 are connected via an access point such as a WiFi router 6. Here, in order to use an AP connection, it is necessary to write the AP's wireless connection information (such as SSID) into the device, but since the means of communication are limited, a direct connection is generally used to temporarily connect the computer terminal 2 and a peripheral device (such as the scanner 4), and the user then configures the AP connection settings.

[0018] In this case, the wireless connection information for direct connections uses a unique SSID and password assigned to each device at the time of shipment from the factory (often attached to the peripheral device itself with a sticker or similar) to prevent unauthorized configuration by third parties, thereby restricting connections from anyone other than the owner of the peripheral device. However, with this method, the user must first actively change the wireless settings of the OS (Operating System) to enable a direct connection, and then change the wireless settings back after completing the AP connection settings. This makes the setup complicated and difficult to understand, and many users find it too burdensome to get started even after the steps are explained. In other words, the problem was that in order to set up an AP connection, it was necessary to set up a direct connection.

[0019] Therefore, the information processing system 1 of this embodiment aims to eliminate the direct connection setup work in the AP connection setup process (making it imperceptible to the user), and automates the wireless connection between the peripheral device and the WiFi router 6 by starting up the peripheral device using a specific startup method and using common wireless connection information for each model, thereby reducing the user's effort. More specifically, as shown in Figure 2, when the user opens the cover of the scanner 4 while pressing the scan button (corresponding to a "specific startup method"), the scanner 4 becomes an access point that uses common wireless connection information (SSID and password), and the computer terminal 2 automatically connects directly to the scanner 4 using the common wireless connection information stored in advance, and the process proceeds to the AP connection setup work.

[0020] FIG. 3 is a diagram illustrating an example of the hardware configuration of the computer terminal 2. As shown in FIG. As shown in FIG. 3, the computer terminal 2 includes a CPU 200, a memory 202, a HDD 204, a network interface 206 (network IF 206), a display device 208, and an input device 210, which are connected to each other via a bus 212. The CPU 200 is, for example, a central processing unit. The memory 202 is, for example, a volatile memory, and functions as a main storage device. The HDD 204 is, for example, a hard disk drive device, and serves as a non-volatile storage device for storing computer programs (for example, the driver program 3 in FIG. 5) and other data files. The network IF 206 is an interface for wired or wireless communication, and realizes connection to, for example, the scanner 4 or the WiFi router 6. The display device 208 is, for example, a liquid crystal display. The input device 210 is, for example, a keyboard and a mouse.

[0021] FIG. 4 is a diagram illustrating an example of the hardware configuration of the control section of the scanner 4. As illustrated in FIG. 4, the scanner 4 includes a CPU 400, a volatile memory 402, a non-volatile memory 404, a network interface 406 (network IF 406), and a touch panel 408, all of which are connected to one another via a bus 412. The CPU 400 is, for example, a central processing unit. The memory 402 is, for example, a volatile memory, and functions as a main storage device. The nonvolatile memory 404 serves as a nonvolatile storage device and stores, for example, computer programs (for example, the scanner program 5 in FIG. 6) and other data files. The network IF 406 is an interface for wired or wireless communication. The touch panel 408 is, for example, a liquid crystal touch panel.

[0022] FIG. 5 is a diagram illustrating an example of the functional configuration of the computer terminal 2. As shown in FIG. 5, in the computer terminal 2 of this example, a driver program 3 is installed and operates, and a connection information database 370 (connection information DB 370) is configured. The driver program 3 is stored in a recording medium such as a CD-ROM, and is installed in the computer terminal 2 via this recording medium. The driver program 3 is a driver program that controls the scanner 4, and includes a connection request unit 300, a setting information transmission unit 310, a setting assistance unit 320, and a scanner control unit 330. Note that the driver program 3 may be partly or entirely implemented by hardware such as an ASIC, or may be implemented by partially borrowing functions of an OS (Operating System).

[0023] In the driver program 3, the connection request unit 300 requests a wireless connection to the scanner 4 using wireless connection information (wireless connection information for settings) stored in the connection information DB 370. The connection information DB 370 is configured when the driver program 3 is installed, and the wireless connection information for settings (common SSID and password) is associated with this driver program 3 and stored in the computer terminal 2. When performing wireless settings for the scanner 4, the connection request unit 300 in this example automatically accesses the scanner 4 using the common SSID and password registered in the connection information DB 370.

[0024] The setting information transmitting unit 310 transmits setting information related to the wireless connection to the scanner 4 using the wireless connection that uses the wireless connection information for setting (first wireless connection information). That is, the setting information transmitting unit 310 transmits setting information (specifically, the SSID and password of the WiFi router 6) for connecting the scanner 4 to the WiFi router 6 to the scanner 4 using the wireless connection established by the connection requesting unit 300.

[0025] The setting assistance unit 320 displays information on the computer terminal 2 to assist in the setting work for connecting the scanner 4 to the WiFi router 6. As shown in FIG. 2, a guidance image showing the user a "specific activation method," an input screen for inputting the password for the WiFi router 6, and the like are displayed on the computer terminal 2.

[0026] The scanner control unit 330, as a driver program for the scanner 4, controls the scanner 4 in response to user operations. For example, the scanner control unit 330 specifies the operation method of the scanner 4 (color / black and white, single-sided / double-sided, resolution, output destination of scanned data, etc.) in response to user operations.

[0027] The connection information DB 370 stores an SSID and a password that are common to each model of the scanner 4. The SSID and password pre-registered in the connection information DB 370 may be common to each type of driver program 3.

[0028] FIG. 6 is a diagram illustrating an example of the functional configuration of the scanner 4. 6, the scanner 4 of this example has a scanner program 5 installed and running, and also has a connection information database 570 (connection information DB 570). The scanner program 5 of this example is pre-installed in the scanner 4, but is not limited to this, and may be stored on a recording medium such as a CD-ROM, and installed in the scanner 4 via this recording medium. The scanner program 5 includes a wireless connection unit 500, a connection information switching unit 510, a setting information receiving unit 520, a connection setting unit 530, and a connection information returning unit 540. Note that the scanner program 5 may be partly or entirely implemented by hardware such as an ASIC, or may be implemented by partially borrowing functions of an OS (Operating System).

[0029] In the scanner program 5, the wireless connection unit 500 establishes a wireless connection using unique wireless connection information (second wireless connection information) that is different from the wireless connection information for settings (first wireless connection information). The unique wireless connection information is wireless connection information that is unique to each scanner 4, such as an SSID and password when the scanner 4 functions as an access point.

[0030] When a predetermined trigger is detected, the connection information switching unit 510 switches the unique wireless connection information used by the wireless connection unit 500 to wireless connection information for setting. For example, the connection information switching unit 510 switches the unique wireless connection information used by the wireless connection unit 500 to wireless connection information for setting on the condition that a predetermined startup operation has been performed. When a predetermined startup operation has been performed and the wireless connection unit 500 has started up in the setting mode, the connection information switching unit 510 in this example switches the unique SSID and password used by the wireless connection unit 500 to an SSID and password common to each model.

[0031] The setting information receiving unit 520 receives setting information from the computer terminal 2 via a wireless connection using the wireless connection information for setting. The setting information receiving unit 520 in this example directly connects to the computer terminal 2 using the wireless connection information for setting, and receives setting information (SSID and password) for connecting to the WiFi router 6 via this wireless connection. The connection setting unit 530 performs settings for connecting to the WiFi router 6 based on the setting information received by the setting information receiving unit 520.

[0032] The connection information returning unit 540 returns the wireless connection information for setting to the unique wireless connection information on the condition that the setting information related to the wireless connection has been received by the setting information receiving unit 520. In this example, the connection information returning unit 540 returns the wireless connection information (common SSID and password) used by the wireless connection unit 500 to the SSID and password unique to the scanner 4 after the setting information receiving unit 520 receives the setting information related to the wireless connection and notifies the computer terminal 2 of that fact. 7, the connection information DB 570 stores a common SSID used in the setting mode and a unique SSID and password used in the normal mode. The common SSID and password are, for example, an SSID and password that are common to each scanner model. For example, the unique SSID includes the serial number of the scanner 4, and the unique password includes a random character string and is different for each scanner.

[0033] FIG. 8 is a sequence diagram illustrating the overall operation (S10) of the information processing system 1. As illustrated in FIG. 8, in step 100 (S100), the computer terminal 2 starts the driver program 3, starts WiFi configuration for the scanner 4, and searches for an access point based on a common SSID that has been registered in advance. In step 105 (S105), the scanner 4 starts to start up when the user presses the power button in a specific start-up method. In step 110 (S110), the scanner 4 starts up in a setting mode and becomes a wireless access point using the common SSID and password.

[0034] In step 115 (S115), the computer terminal 2 discovers the scanner 4 as an access point using the common SSID, and directly connects to the scanner 4 using the common password. In step 120 (S120), the computer terminal 2 displays a password entry screen (FIG. 2) and accepts a password entry by the user. The entered password is for accessing the WiFi router 6. In step 125 (S125), the computer terminal 2 transmits the password entered by the user and the SSID of the WiFi router 6 to the scanner 4 as WiFi setting information.

[0035] In step 130 (S130), the scanner 4 uses the WiFi setting information received from the computer terminal 2 to perform settings for connecting to the WiFi router 6, and establishes a wireless connection with the WiFi router 6. In step 135 (S135), the scanner 4 returns from the setting mode to the normal mode, and restores the wireless connection information when functioning as a wireless access point to the unique SSID and password.

[0036] In step 140 (S140), the computer terminal 2 connects to the WiFi router 6 and searches for the scanner 4 via the WiFi router 6. In step 145 (S145), when the computer terminal 2 finds the scanner 4, it connects to the scanner 4 via the WiFi router 6 and starts using the scanner 4.

[0037] FIG. 9 is a flowchart for explaining in more detail the processing (S20) on the computer terminal side in the information processing system 1. As shown in FIG. 9, in step 200 (S200), the computer terminal 2 starts the driver program 3 (FIG. 5) in response to a user operation, and the driver program 3 waits until the WiFi setting operation of the scanner 4 is started (S200: No). When the WiFi setting operation is started (S200: Yes), the process proceeds to S205.

[0038] In step 205 (S205), the connection request unit 300 reads out the common SSID and password stored in advance in the connection information DB 370, and searches for an access point (scanner 4) using the read out common SSID. In addition, the setting assistance unit 320 displays an image showing a specific activation method on the computer terminal 2, and prompts the user to perform a specific operation on the scanner 4. In step 210 (S210), the connection request unit 300 continues searching until it finds an access point (scanner 4) (S210: No), and when it finds an access point (scanner 4) (S210: Yes), it proceeds to the processing of S215.

[0039] In step 215 (S215), the connection request unit 300 transmits the password read from the connection information DB 370 to the found scanner 4 (access point), and automatically establishes a direct connection with the scanner 4. In step 220 (S220), the setting assistance unit 320 displays a password entry screen and accepts a password entry by the user.

[0040] In step 225 (S225), the setting information transmission unit 310 transmits the password received by the setting assistance unit 320 and the pre-stored SSID of the WiFi router 6 as WiFi setting information to the scanner 4 directly connected by the connection request unit 300. In step 230 (S230), when the connection request unit 300 confirms that the setting information transmission unit 310 has successfully transmitted the WiFi setting information, it disconnects the direct connection with the scanner 4, connects to the WiFi router 6, and searches for the scanner 4 within the LAN (Local Area Network) of the WiFi router 6. In step 235 (S235), when the connection request unit 300 finds the scanner 4 within the LAN of the WiFi router 6, it connects to the scanner 4 via the WiFi router 6, and the scanner control unit 330 starts controlling the scanner 4.

[0041] FIG. 10 is a flowchart for explaining the scanner-side processing (S30) in the information processing system 1 in more detail. 10, in step 300 (S300), the scanner 4 (scanner program 5) determines whether it was started up using a specific start-up method, and if it was started up using the specific start-up method, the process proceeds to S310, and if it was not started up using the specific start-up method, the process proceeds to S305. The specific start-up method is, for example, a method of starting up by opening the cover while pressing the scan button, as exemplified in FIG. 11(A).

[0042] In step 305 (S305), the scanner program 5 (FIG. 6) starts up in normal mode and functions as an access point using a unique SSID and password. In step 310 (S310), the scanner program 5 starts in the setting mode. In step 315 (S315), the connection information switching unit 510 switches the wireless connection information of the wireless connection unit 500 to the common SSID and password.

[0043] In step 320 (S320), the wireless connection unit 500 waits for a request for wireless connection as a wireless access point using the common SSID and password switched by the connection information switching unit 510 (S320: No), and when a request for wireless connection is received, proceeds to processing of S325. In step 325 (S325), the wireless connection unit 500 performs authentication using the common password in response to the wireless connection request and establishes a direct connection with the terminal that made the connection request (computer terminal 2). Once the direct connection is established, the wireless connection unit 500 rejects access requests from other terminals and communicates only with the terminal with which the direct connection has been established.

[0044] In step 330 (S330), the setting information receiving unit 520 receives the WiFi setting information using the direct connection established by the wireless connection unit 500. Upon receiving the WiFi setting information, the setting information receiving unit 520 replies to the computer terminal 2 to inform the computer terminal 2 that the WiFi setting information has been received successfully. In step 335 (S335), the connection setup unit 530 uses the WiFi setting information received by the setting information receiving unit 520 to perform settings for connecting to the WiFi router 6, and establishes a wireless connection to the WiFi router 6.

[0045] In step 340 (S340), the scanner program 5 determines whether the wireless connection to the WiFi router 6 was successful, and if the wireless connection was successful, proceeds to processing of S345, and if the wireless connection was unsuccessful, proceeds to processing of S350. In step 345 (S345), the connection information returning unit 540 returns the wireless connection information to the unique SSID and password, and returns to the normal mode. In step 350 (S350), the scanner program 5 issues an error notification.

[0046] As described above, according to the information processing system 1 of this embodiment, when the scanner 4 is started up using a specific start-up method, the scanner 4 is started up in setting mode and functions as a wireless access point using an SSID and password common to all models, thereby automating a direct connection between the computer terminal 2 and the scanner 4 and enabling WiFi settings for the scanner 4 using this direct connection. In other words, wireless connection settings between the scanner 4 and the WiFi router 6 can be made simply by starting up the scanner 4 and entering the password for the WiFi router 6. As a result, the effort required to use the scanner 4 is significantly reduced, the burden on the user is reduced, and the time required to use the scanner 4 is significantly shortened. In addition, by limiting the period during which a common SSID and password are valid to a short period, security risks can be minimized while enabling simple direct connections.

[0047] Next, a modification of the above embodiment will be described. FIG. 11 illustrates a variation of a particular activation method for the scanner 4. In the above embodiment, the activation method in FIG. 11(A) has been described as a "specific activation method," but this is not limiting. For example, as illustrated in FIG. 11(B), "pressing and holding the scan button after starting the scanner" may be the specific activation method. Furthermore, as illustrated in FIG. 11(C), the initial activation of the scanner may be the "specific activation method." Furthermore, as illustrated in FIG. 11(D), "pressing and holding the scan button five times in succession after starting the scanner" may be the specific activation method. Furthermore, as illustrated in FIG. 11(E), "pressing and holding the scan button for five seconds before starting the scanner" may be the specific activation method. Alternatively, as illustrated in FIG. 11(F), "pressing the scan button five times in succession before starting the scanner" may be the specific activation method.

[0048] In the above embodiment, a common SSID and password are used, but a common SSID may be used without a password. Alternatively, a set of a partially common SSID and a common password may be used.

[0049] Furthermore, in the above embodiment, it is assumed that only one scanner 4 is discovered, but if multiple scanners 4 are discovered, they may be configured to be selectable on the computer terminal 2. There are two methods for selecting a scanner: In the first method, when multiple scanners 4 are discovered, they are connected in the order they are found using a common SSID and password, and then the scanner name is obtained from the information about the scanner 4 and displayed on the screen, with a message such as "Do you want to set up this scanner?" displayed, prompting the user to make a selection. The second pattern is to configure the SSID with a "common part + individual part" (for example, ABCD-EFGH). In other words, the common part (ABCD) is the common SSID, and the individual part (EFGH) is a different string for each scanner. The common part (beginning) of the SSID is determined to be ABCD, and if only one SSID is found, a connection is made; if there are multiple, the individual part (EFGH) is displayed, allowing the user to determine which scanner it is and select it.
