DETAILED DESCRIPTION OF THE INVENTION

[0023] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present disclosure will now be described in detail with reference to the accompanying drawings, in which: Fig. 1 is a diagram showing the system configuration of an image forming apparatus 10 according to an embodiment of the present disclosure;

[0024] The image forming apparatus 10 is a so-called multifunction device that has multiple functions such as printing, scanning, copying, facsimile, etc. The image forming apparatus 10 is an example of an information processing system in the technology of the present disclosure.

[0025] As shown in FIG. 1, the image forming apparatus 10 includes a paper feed tray 10a, a main body 10b, an interface decurler 10c, an interposer 10d, a stacker 10e, a top and bottom trimmer creaser 10f, a paper folding unit 10g, a saddle stitch finisher 10h, and a trimmer folder 10i.

[0026] The paper feed tray 10a is connected to the upstream side of the main body 10b.

[0027] The interface decurler 10c, interposer 10d, stacker 10e, top and bottom trimmer creaser 10f, paper folding unit 10g, saddle stitching finisher 10h, and trimmer folder 10i are connected downstream of the main body 10b and are devices that perform post-processing of printed materials output from the main body 10b.

[0028] The main body 10b of the image forming apparatus 10 includes a user interface (UI) device 15 and an antenna unit 18. The image forming apparatus 10 is configured to be able to perform wireless communication with a user terminal 20 via the antenna unit 18.

[0029] The user terminal 20 is a terminal for using the functions of the image forming apparatus 10. The user terminal 20 includes a display unit 21 for displaying a screen.

[0030] Fig. 2 is a block diagram showing the hardware configuration of image forming apparatus 10. As shown in Fig. 2, image forming apparatus 10 has a CPU (Central Processing Unit) 11, a RAM (Random Access Memory) 12, a storage device 13 such as a hard disk drive, a communication interface (abbreviated as IF) 14, a UI device 15, a scanner 16, a print engine 17, and an antenna unit 18. These components are connected to each other via a control bus 19.

[0031] The CPU 11 is a processor that controls the operation of the image forming apparatus 10 by executing predetermined processes based on a program stored in the RAM 12 or the storage device 13. While the present embodiment has been described as the CPU 11 reading and executing a program stored in the RAM 12 or the storage device 13, this is not limiting. The program may be provided in a form recorded on a computer-readable recording medium. For example, the program may be provided in a form recorded on an optical disc such as a CD (Compact Disc)-ROM (Read Only Memory) or a DVD (Digital Versatile Disc)-ROM, or in a semiconductor memory such as a USB (Universal Serial Bus) memory or a memory card. The program may also be acquired from an external device via a communication line connected to the communication interface 14.

[0032] The communication IF 14 transmits and receives data to and from external devices. The UI device 15 includes a touch panel that displays a screen and accepts user input, and physical buttons with predetermined functions set thereon. The scanner 16 reads an original document loaded into the image forming apparatus 10 as image data. The print engine 17 prints an image on a recording medium such as printing paper through processes such as charging, exposure, development, transfer, and fixing.

[0033] The antenna unit 18 includes two antennas 18a and 18b. The antenna unit 18 connects to the user terminal 20 by a wireless communication method such as Bluetooth (registered trademark) version 5.1 (hereinafter referred to as Bluetooth 5.1).

[0034] In Bluetooth 5.1, not only the propagation distance of the radio wave received from the user terminal 20 but also the reception angle of the radio wave received from the user terminal 20 can be obtained using two antennas 18a and 18b.

[0035] Here, the principle of obtaining the reception angle will be explained. As shown in Fig. 3, radio waves incident at a certain angle θ are received with different phases by the two antennas 18a and 18b. In the example of Fig. 3, a phase difference φ occurs between antenna 18a and antenna 18b because the propagation distance of antenna 18a is longer.

[0036] Since the distance d between the two antennas 18a and 18b and the wavelength λ of the radio wave are known, the reception angle θ can be calculated by the following formula (1). (φλ / 2π) / d=cosθ (1)

[0037] The acquisition of information about the distance and angle of the user terminal 20 relative to the image forming apparatus 10 is not limited to the above-described method using Bluetooth 5.1, and any method may be used.

[0038] Fig. 4 is a block diagram showing the functional configuration of the image forming apparatus 10. As shown in Fig. 4, the image forming apparatus 10 of this embodiment includes a control unit 31, a display input unit 32, a data transmission / reception unit 33, a terminal position detection unit 34, an authentication unit 35, a storage unit 36, an image reading unit 37, and an image output unit 38.

[0039] The control unit 31 controls the overall operation of the image forming apparatus 10, and controls the reading of the document image by the image reading unit 37 and the output of print data from the image output unit 38 based on instructions input from the user.

[0040] The control unit 31 can also execute a process called mirroring, which causes the display content of the touch panel that constitutes the display input unit 32 to be displayed on the display unit 21 of the user terminal 20 .

[0041] The display input unit 32 is configured by the UI device 15, and displays various information to the user and inputs information on various operations performed by the user. The data transmission / reception unit 33 transmits and receives data to and from external devices such as the user terminal 20. The terminal position detection unit 34 acquires information on the distance and angle of the user terminal 20 relative to the image forming device 10 based on the radio wave reception status of the antenna unit 18. The authentication unit 35 executes authentication processing for a user who attempts to use the image forming device 10.

[0042] The storage unit 36 ​​stores various data such as programs for controlling the operation of the image forming apparatus 10. The image reading unit 37 reads an original image from a loaded original based on the control of the control unit 31. The image output unit 38 outputs an image onto a recording medium such as printing paper based on the control of the control unit 31.

[0043] As described above, the image forming apparatus 10 of this embodiment is composed of multiple devices, including a paper feed tray 10a, a main body 10b, an interface decurler 10c, an interposer 10d, a stacker 10e, a top and bottom trimmer creaser 10f, a paper folding unit 10g, a saddle stitching finisher 10h, and a trimmer folder 10i.

[0044] If an error occurs in any of these devices, the error is displayed on the UI device 15 of the main body 10b as shown in FIG.

[0045] Specifically, when an error occurs, the control unit 31 displays an error notification screen. On the error notification screen, the device in the image forming apparatus 10 where the error occurred is displayed in color, and the device in which the error occurred is notified. When the "Error Information" button 41 is touched on the error notification screen, the control unit 31 displays an error list screen.

[0046] The error list screen displays in color any device in the image forming apparatus 10 in which an error has occurred, and displays a list of errors that have occurred in the image forming apparatus 10. In the example of FIG. 5, "1 Paper Jam: Trimmer Folder" is displayed. When the "1 Paper Jam: Trimmer Folder" button 42 is touched on the error list screen, the control unit 31 displays a paper jam removal procedure display screen. Furthermore, when the "Close" button 43 is touched on the error list screen, the control unit 31 displays an error notification screen.

[0047] The paper jam removal procedure display screen displays a detailed explanation of the procedure for removing a paper jam in the trimmer folder 10i. The user can clear the paper jam in the trimmer folder 10i while viewing the paper jam removal procedure display screen. When the "Close" button 44 is touched on the paper jam removal procedure display screen, the control unit 31 displays an error list screen.

[0048] Here, the main body 10b equipped with the UI device 15 is arranged second from the left in the image forming device 10 in the figure, and the trimmer folder 10i is arranged ninth from the left (i.e., the rightmost) in the image forming device 10 in the figure.

[0049] That is, since six devices are arranged between the main body 10b and the trimmer folder 10i, it is difficult for the user to operate the trimmer folder 10i while checking the UI device 15 of the main body 10b. Therefore, by performing mirroring to display the display content of the UI device 15 on the display unit 21 of the user terminal 20, the user can operate the trimmer folder 10i while looking at the user terminal 20 at hand.

[0050] In this case, if a screen displaying the procedure for clearing the error in a device is automatically displayed when the user approaches the device in which the error has occurred, user convenience can be improved.

[0051] In order to meet such demands, the control unit 31 of the image forming device 10 of this embodiment acquires information on the distance and angle of the user terminal 20 relative to a specific position, and when it detects that the user terminal 20 is within a range set based on a specific area among the multiple areas of the image forming device 10 using the information on the distance and angle of the user terminal 20, it displays a screen corresponding to the specific area on the display unit 21 of the user terminal 20.

[0052] For example, if an error occurs in the trimmer folder 10i, the range within 1 m from the trimmer folder 10i is regarded as the work range for dealing with the error, and if it is detected that the user terminal 20 is within this work range, a paper jam removal procedure display screen for the trimmer folder 10i can be displayed on the display unit 21 of the user terminal 20.

[0053] As shown in FIG. 6, when only information about the distance of the user terminal 20 relative to a specific position is acquired, there may be cases where the device that the user is facing directly at a certain distance is different.

[0054] In contrast, the image forming apparatus 10 of this embodiment acquires information on the distance and angle of the user terminal 20 relative to a specific position. Also, as shown in Fig. 7, a device management table is stored in the storage unit 36 ​​of the image forming apparatus 10, in which distance information for each device from a reference position is recorded. By using this information, the image forming apparatus 10 of this embodiment can accurately identify the device that the user is facing directly.

[0055] In the image forming device 10 of this embodiment, as in the example above, when an error occurs in the image forming device 10, the control unit 31 uses the distance and angle information of the user terminal 20 to detect that the user terminal 20 is within a range set based on the area where the error occurred, and then displays a screen for dealing with the error corresponding to the area where the error occurred on the display unit 21 of the user terminal 20.

[0056] In this case, if errors occur in multiple areas, the control unit 31 may display a screen for dealing with errors on the display unit 21 of the user terminal 20 only for the one area in which the error with the highest priority has occurred.

[0057] Furthermore, when an error occurs, the control unit 31 performs a mirroring process to display the display content of the display input unit 32 on the display unit 21 of the user terminal 20.

[0058] In this case, the control unit 31 may stop the mirroring process when the error is resolved.

[0059] In the image forming device 10 of this embodiment, the control unit 31 may use information on the distance and angle of the user terminal 20 to notify the user via the user terminal 20 when it detects that the user terminal 20 is within a distance of a set threshold from a range set based on a specific area.

[0060] For example, if an error occurs in the trimmer folder 10i, the range within 1 m of the trimmer folder 10i can be regarded as the working range for dealing with the error, and a position 2 m from this working range can be set as the threshold, and if the user approaches within 2 m of the working range, the user can be notified via the user terminal 20.

[0061] The notification method may be any method, such as displaying a message such as "You are 2 meters away from the target device" on the display unit 21 of the user terminal 20, lighting up an indicator indicating that the target device has been approached, or emitting a notification sound.

[0062] Next, the flow of error display processing during mirroring (that is, during remote connection) in the image forming apparatus 10 of this embodiment will be described with reference to the flowchart of FIG.

[0063] First, in step S11, the control unit 31 determines whether or not a remote connection with the user terminal 20 is in progress.

[0064] If it is determined in step S11 that the remote connection is not in progress, the control unit 31 ends the process.

[0065] If it is determined in step S11 that a remote connection is in progress, the control unit 31 acquires information on the distance and angle of the user terminal 20 in step S12.

[0066] Next, in step S13, the control unit 31 determines whether or not the position of the user terminal 20 has changed.

[0067] If it is determined in step S13 that there has been no change in the position of the user terminal 20, the control unit 31 proceeds to step S12.

[0068] If it is determined in step S13 that the position of the user terminal 20 has changed, the control unit 31 executes the loop process from step S14 to step S20 as many times as the number of devices included in the image forming apparatus 10.

[0069] In the loop process, first, in step S15, the control unit 31 acquires the location information of the device from the device management table.

[0070] Next, in step S16, the control unit 31 checks the position of the user terminal 20 and determines whether the position of the user terminal 20 is within the working range of the device.

[0071] If it is determined in step S16 that the location of the user terminal 20 is outside the working range of the device, the control unit 31 proceeds to step S14.

[0072] If it is determined in step S16 that the position of the user terminal 20 is within the working range of the device, the control unit 31 determines in step S17 whether or not an error has occurred in the device.

[0073] If it is determined in step S17 that no error has occurred in the device, the control unit 31 proceeds to step S20.

[0074] If it is determined in step S17 that an error has occurred in the device, the control unit 31 determines in step S18 whether the priority of the error in the device is the highest among the errors currently occurring in the image forming device 10.

[0075] If it is determined in step S18 that the error priority of the device is not the highest, the control unit 31 proceeds to step S20.

[0076] If it is determined in step S17 that the error of the device has the highest priority, the control unit 31 displays a screen on the display unit 21 of the user terminal 20 in step S19 to resolve the error of the device, and then terminates the processing.

[0077] [Variations] The image forming apparatus 10 has been described above as one embodiment of the information processing system of the present disclosure, but the technology of the present disclosure is not limited to the above embodiment and can be modified as appropriate.

[0078] For example, in the above embodiment, an example was described in which the present invention is applied to displaying an error when an error occurs in the image forming device 10, but it can also be applied in other ways than displaying an error, such as displaying diagnostic items during device diagnosis in the image forming device 10.

[0079] Furthermore, the present invention can be applied not only to the image forming apparatus 10 but also to various information processing systems such as a production line in a factory or a conveyance system in a warehouse.
