  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following description, the same parts are denoted by the same reference numerals. Their names and functions are also the same. Therefore, detailed description thereof will not be repeated.

<A. Overall system configuration>
First, the overall configuration and operation outline of image forming system 1000 according to the embodiment of the present invention will be described.

  FIG. 1 is a schematic diagram showing an overall configuration of an image forming system 1000 according to the present embodiment.

  Referring to FIG. 1, image forming system 1000 according to the embodiment of the present invention is generically referred to as image forming apparatus 10 and communication apparatuses 20A and 20B (hereinafter referred to as “communication apparatus 20”) respectively attached to user A and user B. ). The image forming apparatus 10 includes antennas 40A to 40D (hereinafter collectively referred to as “antenna 40”) and communication cables 50A to 50D (hereinafter “communication cable 50”) that connect the image forming apparatus 10 main body and the antennas 40A to 40D, respectively. Also collectively).

  The image forming apparatus 10 is, for example, a digital multi-function peripheral having a document transport function for sequentially transporting a plurality of documents and a re-transport function for automatically performing double-sided copying.

  The communication device 20 is a communication device that is attached to a user and capable of human body communication. Specifically, a battery is stored inside the communication device, and an electric field is generated by the battery to exchange data with the mat type antenna 40 via the human body. The communication device 20 stores user information for identifying each user.

  The antenna 40 is disposed in the vicinity of the main body of the image forming apparatus 10 and receives data transmitted through the human body. The received data is transmitted to the main body of the image forming apparatus 10 via the corresponding communication cable 50. Each antenna 40 is disposed in the vicinity of the four directions of the image forming apparatus 10. Each antenna 40 can receive data from the communication device 20 and detect that a user has stood in a corresponding area in the vicinity of the image forming apparatus 10.

  FIG. 2 is a plan view for illustrating an arrangement method of antenna 40 arranged in the vicinity of image forming apparatus 10 according to the present embodiment.

  Referring to FIG. 2, antenna 40A is arranged in area A in the vicinity of the operation panel in image forming apparatus 10, and antenna 40B is arranged in area B in the vicinity of a USB (Universal Serial Bus) connection port or hand tray that is not shown. The antenna 40C is disposed in a region C near the ADF (Auto Document Feeder), and the antenna 40D is disposed in a region D near the paper discharge port. Regions A to D correspond to user detection regions in antennas 40A to 40D, respectively. The antenna 40 may transmit and receive data to and from the main body of the image forming apparatus 10 by wireless communication without using the communication cable 50.

  With such a configuration, for example, when the user A wearing the communication device 20A stands on the antenna 40A, the image forming apparatus 10 transmits user information for identifying the user A from the communication device 20A via the antenna 40A. At the same time, it is detected that the user A stands in the area A. Then, in the state where the user A is detected, when the user B wearing the communication device 20B later stands on the antenna 40B, the image forming apparatus 10 determines that the user B has stood in the area B after the user A. Is detected. The image forming apparatus 10 recognizes the user A as a main user with a high priority regarding the use of the image forming apparatus 10 with respect to the user B, and recognizes the user B as a sub user with a low priority with respect to the user A. . That is, the image forming apparatus 10 recognizes the user detected first in any one of the regions A to D as the main user and the user detected later as the sub user.

  Here, it will be described that the execution of the image forming apparatus 10 of the function associated with the area where the sub user exists is restricted in relation to the function associated with the area where the main user exists.

  FIG. 3 shows a function correspondence table provided by image forming apparatus 10 according to the present embodiment.

  With reference to FIG. 3, first, it will be described that a plurality of functions of the image forming apparatus 10 are associated with the areas A to D, respectively. The area A is associated with, for example, a UI (User Interface) function using an operation panel. More specifically, a copy function, a scan function, a box function, and a browser function using the operation panel. The box function is a function that allows data to be stored in a hard disk or the like built in the image forming apparatus 10 and retrieved when necessary to use the data.

  Area B is associated with the USB function and the manual feed tray function. Specifically, the USB function is a function for printing out image data stored in a USB memory based on a predetermined program by connecting a USB memory to a USB connection port arranged in the image forming apparatus 10. Etc. The manual feed tray function is a function for outputting (printing) predetermined image data on a paper medium by placing the paper medium on the manual feed tray. It should be noted that a button for the user to instruct the image forming apparatus 10 to perform print output or the like may be disposed on the housing of the image forming apparatus 10 near the region B.

  Area C is associated with an ADF function for automatically feeding a document. In the area C, the user can cause the image forming apparatus 10 to execute a copy and scan function using the ADF function. Note that a button or the like for the user to instruct the image forming apparatus 10 to perform copying, scanning, or the like may be disposed on the housing of the image forming apparatus 10 near the region C.

  Area D is associated with the paper discharge function. With the paper discharge function, when it is detected that the user exists in the area D, the image data stored in the memory of the image forming apparatus 10 is output (printed) on a paper medium and discharged. This is a function for discharging paper from the paper.

  As described above, the function of the image forming apparatus 10 that is assumed to be used by the user in the area is associated with each area. The association between the area and the function is an exemplification, and may be appropriately changed depending on the apparatus configuration of the image forming apparatus 10 or may be arbitrarily changed by the user.

  With this association, for example, when the main user exists in the area A and uses the box function, the sub user cannot use the UI function of the area A and the ADF function of the area C (cannot be used). ), The USB function or manual tray function in area B and the paper discharge function in area D can be used (can be used). That is, the image forming apparatus 10 determines whether or not the function associated with the area where the sub user exists can be executed based on the function associated with the area where the main user exists.

  When the image forming apparatus 10 determines that the function can be executed, the sub-user can use the function to permit the execution of the function. On the other hand, if the image forming apparatus 10 determines that the function cannot be executed, the sub user cannot use the function because the execution of the function is prohibited. As described above, the restriction of the function associated with the area where the sub user exists based on the function associated with the area where the main user exists prevents the main user from using the image forming apparatus 10 as much as possible. This is to allow the sub-user to use the image forming apparatus 10 within the range. Therefore, with regard to the patterns in which the sub-user cannot be used or can be used as shown in FIG. If possible, other pattern settings may be used. Further, the user may be able to change the pattern setting according to the application.

  According to the above configuration, the use of the sub-user image forming apparatus can be realized within a range that does not hinder the use of the main user image forming apparatus. Therefore, even when the use timings of the image forming apparatuses of a plurality of users overlap, the plurality of users can use the image forming apparatus more efficiently.

(Modification of the system)
Next, as a modification of the image forming system 1000 described above, an overall configuration and an outline of operation of the image forming system 1100 will be described.

  FIG. 4 is a schematic diagram showing an overall configuration of image forming system 1100 according to the present embodiment.

  Referring to FIG. 4, image forming system 1100 according to the embodiment of the present invention includes an image forming device 10, communication devices 20 </ b> A and 20 </ b> B, and a terminal device 30. Image forming apparatus 10 includes antennas 40A to 40D and communication cables 50A to 50D. That is, the image forming system 1100 is different in that a terminal device 30 is added to the image forming system 1000. The detailed description of the same points as the image forming system 1100 in the image forming system 1100 will not be repeated, and different points will be described.

  FIG. 4 shows a scene in which the main user exists in the area A and the sub user exists in the area C. The main user is assumed to use the browser function in the area A. At this time, according to the example of FIG. 3, the sub-user existing in the area C scans the document by instructing the image forming apparatus 10 through a button or the like using the ADF function, for example. Is possible. However, since there is no operation panel in the vicinity of the area C, it is impossible to make detailed reading settings regarding scanning. Therefore, the image forming apparatus 10 transmits display data for displaying the user interface screen 700 corresponding to the ADF function associated with the area C to the terminal device 30 previously associated with the user information of the sub user. Note that destination information of the terminal device 30 associated with the user information is registered in the memory 110 of the image forming apparatus 10 in advance.

  In the example of FIG. 4, the user interface screen 700 includes a setting key 710 for setting a resolution, a setting key 720 for setting a file format, an execution key 730 for executing a scan, and a cancel key 740. including. When the sub user instructs the terminal device 30 by selecting the setting keys 710, 720, the execution key 730, etc. on the user interface screen 700, a signal based on the instruction is transmitted from the terminal device 30 to the image forming apparatus 10, The image forming apparatus 10 executes processing based on the signal.

  According to the configuration as described above, even though the sub-user can use the function associated with the area where the user exists in the relationship with the main user, the operation panel (UI function) cannot be used. A user interface screen corresponding to the function is displayed on the terminal device 30 associated with the sub user. Therefore, the sub-user can carry out detailed settings related to the function associated with the area by carrying the terminal device 30 associated with the sub-user and entering the predetermined area. Then, the sub user can cause the image forming apparatus 10 to execute processing based on the setting.

  Further, as a similar form, the sub user may use the UI function through a remote panel associated with the image forming apparatus 10 in advance. The remote panel is a dedicated remote operation panel for remotely operating the image forming apparatus 10. For example, the remote panel is an input unit configured integrally with a key input unit as an input unit and a display for displaying an operation screen. Including touch panel.

  The housing of the image forming apparatus 10 is provided with a plurality of sensors for detecting a remote panel, for example. More specifically, each sensor is provided in the housing of the image forming apparatus 10 near each corresponding region. When the sub user can use the function associated with the area where the sub user is present in relation to the main user, the sub user holds the remote panel over the sensor provided in the vicinity of the area and displays it on the remote panel display. A user interface screen (for example, a user interface screen 700 as shown in FIG. 4) corresponding to the function associated with the area is displayed. By giving an instruction via the remote panel, the sub-user transmits a signal based on the instruction from the remote panel to the image forming apparatus 10, and the image forming apparatus 10 executes processing based on the signal.

<C. Functional configuration>
FIG. 8 is a block diagram showing a functional configuration of image forming apparatus 10 according to the present embodiment.

  Referring to FIG. 8, image forming apparatus 10 has, as main functional configurations, area determination unit 502, priority determination unit 504, execution determination unit 506, acquisition unit 508, user authentication unit 510, and registration unit 512. And a first communication unit 514 and a second communication unit 516. These configurations are basically realized by the CPU 100 of the image forming apparatus 10 executing a program stored in the memory 110 and giving a command to the components of the image forming apparatus 10. That is, the CPU 100 has a function as a control unit that controls the entire operation of the image forming apparatus 10. Further, the image forming apparatus 10 includes an antenna 40 that functions as a detection unit that detects a user, and a sensor 192 that functions as a device detection unit that detects the remote panel 60. As described above, some or all of these functional configurations may be realized by hardware.

  Based on the detection result of the antenna 40, the region determination unit 502 determines in which region of the plurality of regions the user exists. More specifically, the region determination unit 502 includes the user in which region of the plurality of antennas 40 depending on which antenna of the antennas 40A to 40D corresponding to each of the regions A to D is received. Determine whether to do. For example, the area determination unit 502 determines that the user exists in the area A when receiving a detection signal from the antenna 40A. Then, the region determination unit 502 sequentially outputs the determination results to a priority determination unit 504 described later.

  The priority determination unit 504 is based on a predetermined determination criterion, and the user who is determined by the region determination unit 502 to be present in one region among the plurality of regions and the user who is present in another region among the plurality of regions. Then, the priority order regarding the use of the image forming apparatus 10 with another user determined by the area determination unit 502 is determined. Here, a user with a high priority regarding the use of the image forming apparatus 10 can preferentially use the functions of the image forming apparatus 10 associated with the area in which the user is present. A user with a low priority may be restricted (cannot use) from using a function associated with an area in which the user with a high priority exists in relation to a function associated with an area in which a user with a high priority exists. is there.

  In another aspect, the priority determination unit 504 determines that a user detected earlier by the antenna 40 has a higher priority. More specifically, for example, when the region determination unit 502 receives the detection signal from the antenna 40A earlier than the detection signal from the antenna 40B, the priority determination unit 504 selects a user existing in the region A. The user existing in the area B is determined as a user having a higher priority, and the user existing in the area B is determined as a user having a lower priority than the user existing in the area A.

  Based on the first function associated with the area where the user with high priority exists, the execution determining unit 506 performs the second function associated with the area where the user with low priority exists. Determine if it can be executed. More specifically, the execution determination unit 506 refers to a function correspondence table (for example, FIG. 3) stored in advance in the memory 110 and determines the second function based on the first function. It is determined whether or not can be executed.

  In another aspect, the execution determination unit 506 determines whether the image forming apparatus 10 can execute the second function based on the function being executed by the image forming apparatus 10 among the first functions. More specifically, with reference to the example of FIG. 3, when the first function is the UI function, the execution determination unit 506 includes the copy, scan, box, and browser functions included in the UI function. Of these, it is determined whether the image forming apparatus can execute the second function based on the function being executed. For example, consider a case where a user with high priority exists in the area A and a user with low priority exists in the area C. At this time, if the image forming apparatus 10 is executing the copy function, the execution determination unit 506 determines that the ADF function cannot be executed, and prohibits the execution of the function. On the other hand, when the image forming apparatus 10 is executing the browser function, the execution determining unit 506 determines that the ADF function can be executed and permits the execution of the function.

  The acquisition unit 508 acquires user information from the communication device 20 worn by the user by performing human body communication. More specifically, the acquisition unit 508 acquires user information stored in the memory 210 of the communication apparatus 20 from the communication unit 240 via the communication interface 120 and the antenna 40 using the human body as a medium.

  The user authentication unit 510 executes user authentication processing for the image forming apparatus 10. More specifically, the user authentication unit 510 performs authentication processing on the image forming apparatus 10 based on the user information of the user detected by the antenna 40 acquired by the acquisition unit 508.

  The registration unit 512 registers the default setting regarding the execution contents of the function associated with the area in association with the user authenticated by the user authentication unit 510 (hereinafter also referred to as “authenticated user”). More specifically, the registration unit 512 registers processing executed by the image forming apparatus 10 by default for the function associated with the area where the authenticated user is detected.

Here, the registration of the default setting will be specifically described with reference to FIG.
FIG. 9 is a diagram showing an example of a registration screen for registering default settings relating to the execution contents of the functions of image forming apparatus 10 according to the present embodiment.

  Referring to FIG. 9, on the registration screen displayed on the display of operation panel 170, four default settings are registered for each area. FIG. 9 shows a case where, for example, default settings 1 to 4 are registered in the area C. Here, the ADF function that is a function associated with the region C will be described. It is assumed that the user A has registered in the setting 3 a process of scanning a document and transmitting the scanned image data to a predetermined destination when the document is set on the document table of the ADF 190. In this case, if the user A selects the setting 3 as the default setting, the user A is detected as a sub-user in the area C, and if it is determined that the image forming apparatus 10 can execute the ADF function, When the user A sets a document on the document table, the document is scanned and the scanned image data is transmitted to the predetermined destination.

  When there is no UI function in the area where the user is detected, it is assumed that it is difficult for the user to make detailed settings. Therefore, the user can cause the image forming apparatus 10 to execute a desired process related to the function associated with the area by registering default settings in advance.

  If the execution determination unit 506 determines in another aspect that the image forming apparatus 10 can execute the function associated with the area where the authenticated user exists, the execution determination unit 506 determines that the function is based on the default setting described above. The forming apparatus 10 is caused to execute.

  The first communication unit 514 transmits the display data of the user interface screen corresponding to the function associated with the area, which is an area where the authenticated user exists, to the terminal device 30 previously associated with the authenticated user. The first communication unit 514 refers to the memory 110 and transmits the display data to the terminal device 30 based on the destination information of the terminal device 30 associated with the user information of the authenticated user. The first communication unit 514 is realized mainly by the CPU 100 and the network interface 160 operating in cooperation.

  The second communication unit 516 is an area where a user carrying the remote panel detected by the sensor 192 exists, and transmits display data of a user interface screen corresponding to a function associated with the area to the remote panel. To do. The second communication unit 516 is realized mainly by the CPU 100 and the panel communication unit 194 operating in cooperation.

<D. Processing example>
A processing procedure of a processing example executed by image forming apparatus 10 according to the present embodiment will be described. Specifically, a processing procedure of a processing example of the image forming apparatus 10 when a plurality of users use the function of the image forming apparatus 10 will be described.

(D1. Processing example (1))
FIG. 10 is a flowchart showing a processing procedure in a processing example (part 1) of image forming apparatus 10 according to the embodiment of the present invention. It is assumed that the user wears the communication device 20 capable of human body communication. Here, the predetermined user already exists in any one of the plurality of areas described above (detected by the image forming apparatus 10), and the user authentication for the image forming apparatus 10 is performed. Shall. In addition, the predetermined user uses a function associated with the existing area, and the predetermined user is also described as a previous user. The matters described above are the same in the following processing examples (No. 2) to (No. 4).

  Referring to FIG. 10, CPU 100 determines whether or not a user has been detected based on a detection signal from antenna 40 disposed in the vicinity of image forming apparatus 10 via human body communication (step S <b> 102). More specifically, the CPU 100 determines whether a signal from the communication device 20 worn by the user is received via the communication interface 120 and the antenna 40. At this time, the CPU 100 may determine whether or not a user has been detected based on whether or not user information has been received from the communication device 20.

  CPU 100 repeats the process of step S102 when the user is not detected (NO in step S102). In contrast, when CPU 100 detects a user (YES in step S102), CPU 100 acquires user information of the detected user from communication device 20 and executes authentication processing for image forming device 10. (Step S103).

  Next, the CPU 100 determines in which detection area of the areas A to D the user is detected (step S104). More specifically, the CPU 100 determines in which region the user is detected based on detection signals from the plurality of antennas 40 provided corresponding to the plurality of regions, respectively. For example, when receiving a detection signal from the antenna 40A, the CPU 100 determines that the user exists in the area A.

  Next, the CPU 100 determines the priority order regarding the use of the image forming apparatus 10 by the previous user that already existed in any area and the subsequent user detected in any area after the previous user ( Step S106). More specifically, the CPU 100 determines the priorities of the previous user and the subsequent user based on the priority determination criteria stored in the memory 110. In this example, it is assumed that the CPU 100 determines that a user detected earlier through the antenna 40 has a higher priority. Therefore, the CPU 100 determines the previous user as a user (main user) having a high priority and determines the subsequent user as a user (sub user) having a low priority.

  Next, based on the function associated with the area where the main user exists (hereinafter also referred to as “main function”), the CPU 100 also refers to the function associated with the area where the sub user exists (hereinafter also referred to as “sub function”). It is determined whether the image forming apparatus 10 can execute (.). More specifically, the CPU 100 refers to a function correspondence table as shown in FIG. 3 stored in the memory 110 and determines whether the image forming apparatus 10 can execute the sub function. For example, referring to the example of FIG. 3, in the CPU 100, when the main user exists in the area A and the image forming apparatus 10 is executing the scan function, the sub user exists in the area B or D. Only when it is determined that the function associated with each region can be executed. Here, it is assumed that the sub user is detected in an area different from the area where the main user exists. When the sub user enters the same area as the main user, the CPU 100 uses a warning sound through a speaker (not shown) to prevent the sub user from hindering the use of the image forming apparatus 10 of the main user. The user may be warned to leave the area.

  If the CPU 100 determines that the image forming apparatus 10 can execute the function (YES in step S108), the CPU 100 permits the execution of the sub-function image forming apparatus 10 (step S110). Then, the CPU 100 causes the image forming apparatus 10 to execute a process according to each instruction from the main user and the sub user (step S112). That is, the main user and the sub user can use the functions of the image forming apparatus 10 associated with their own area in parallel. Then, the CPU 100 ends the process.

  On the other hand, when the CPU 100 determines that the image forming apparatus 10 cannot execute the function (NO in step S108), the CPU 100 prohibits the execution of the sub-function image forming apparatus 10 (step S114). Then, the CPU 100 notifies the sub user of an error (step S116). More specifically, the CPU 100 notifies the sub user that the function associated with the area where the sub user exists cannot be executed. Then, the CPU 100 ends the process.

  In the above description, the user information is acquired and the user authentication is performed. However, the user authentication may be performed. For example, the image forming apparatus 10 may recognize a user who first stands in any area as a user with the highest priority, and a user who stands in any area next as the user with the second highest priority. Therefore, it is not always necessary to perform user authentication. In other words, as long as the image forming apparatus 10 can identify in which area the user with which priority exists, the user authentication may not be performed.

  According to the above processing example (part 1), the use of the sub-user image forming apparatus can be realized within a range that does not hinder the use of the main user image forming apparatus. That is, even when the use timings of the image forming apparatuses 10 of a plurality of users overlap, each user can use the image forming apparatus 10 simultaneously in parallel. Therefore, the user can use the image forming apparatus 10 more efficiently, and the convenience for the user is improved.

(D2. Processing example (2))
In the processing example (No. 2), a case where the image forming apparatus 10 executes processing based on the default setting described in FIG. 9 will be described.

  FIG. 11 is a flowchart showing a processing procedure in a processing example (part 2) of image forming apparatus 10 according to the embodiment of the present invention.

  Referring to FIG. 11, CPU 100 executes the processes from steps S102 to S108. Since the processing from step S102 to S108 is the same as the processing described in the processing example (part 1), detailed description thereof will not be repeated.

  If the CPU 100 determines in step S108 that the image forming apparatus 10 cannot execute the sub function (NO in step S108), the CPU 100 executes the processes in steps S114 and S116 and ends the process. Since the process of step S114 and step S116 is the same as the process demonstrated in the process example (the 1), the detailed description is not repeated.

  On the other hand, if the CPU 100 determines that the image forming apparatus 10 can execute the sub function (YES in step S108), the CPU 100 permits the execution of the image forming apparatus 10 having the sub function (step S110). Then, the CPU 100 determines whether or not the default setting of the execution content related to the sub function is registered in advance (step S202). In other words, the CPU 100 determines whether processing executed by the image forming apparatus 10 by default is registered for the function associated with the area where the sub-user exists.

  If the default setting is not registered in advance (NO in step S202), CPU 100 causes image forming apparatus 10 to execute processing in accordance with each instruction from the main user and the sub user (step S112). Then, the CPU 100 ends the process.

  On the other hand, when the default setting is registered in advance (YES in step S202), the CPU 100 causes the image forming apparatus 10 to execute a process according to an instruction from the main user and relates to the sub function. The image forming apparatus 10 is caused to execute processing based on the default setting (step S204). Then, the process ends.

  According to the above processing example (part 2), it is possible to cause the image forming apparatus 10 to execute processing based on the default setting while having the advantages of the processing example (part 1). Therefore, if the user registers in advance processing that the image forming apparatus 10 wants to execute by default, a detailed instruction is given to the image forming apparatus 10 because the operation panel 170 is not present in the area where the user exists. Even if it is not possible, the registered desired process can be executed. In addition, although the example regarding a sub user was mainly demonstrated above, the main user may be a case where the process based on default setting is made, such as when the operation panel 170 is not in the area | region where he exists.

(D3. Processing Example (Part 3))
In the processing example (No. 3), as described with reference to FIG. 4, when the sub-user carries the terminal device 30 associated with the user and enters the one of a plurality of areas and uses the image forming apparatus 10. Next, a processing procedure executed by the image forming apparatus 10 will be described.

  FIG. 12 is a flowchart showing a processing procedure in a processing example (part 3) of image forming apparatus 10 according to the embodiment of the present invention.

  Referring to FIG. 12, CPU 100 executes the processes from steps S102 to S108. Since the processing from step S102 to S108 is the same as the processing described in the processing example (part 1), detailed description thereof will not be repeated.

  If the CPU 100 determines in step S108 that the image forming apparatus 10 cannot execute the sub function (NO in step S108), the CPU 100 executes the processes in steps S114 and S116 and ends the process. Since the process of step S114 and step S116 is the same as the process demonstrated in the process example (the 1), the detailed description is not repeated.

  On the other hand, if the CPU 100 determines that the image forming apparatus 10 can execute the sub function (YES in step S108), the CPU 100 permits the execution of the image forming apparatus 10 having the sub function (step S110).

  Next, the CPU 100 determines whether or not the area where the sub-user exists is an area where the UI function can be used (step S302). More specifically, the CPU 100 determines whether or not it exists in an area (area A in the case of FIG. 3) where the sub user can give an instruction to the image forming apparatus 10 using the operation panel 170. Determine whether.

  If the sub-user exists in an area where the UI function can be used (YES in step S302), the CPU 100 causes the image forming apparatus 10 to execute processing according to each instruction from the main user and the sub-user ( Step S112). Then, the CPU 100 ends the process.

  On the other hand, when the sub user does not exist in the area where the UI function can be used (NO in step S302), the CPU 100 connects the terminal device 30 associated with the sub user via the network interface 160. The display data of the user interface screen corresponding to the sub function is transmitted (step S304). Then, the CPU 100 causes the image forming apparatus 10 to execute processing based on the data received from the terminal device 30 via the network interface 160 (step S306). More specifically, when a sub user gives a predetermined instruction to the terminal device 30 on a user interface screen (for example, the user interface screen 700 in FIG. 4) displayed on the terminal device 30, a signal based on the instruction Is transmitted from the terminal device 30 to the image forming apparatus 10. The CPU 100 causes the image forming apparatus 10 to execute processing based on the received signal. That is, the sub-user can use the terminal device 30 to instruct the image forming apparatus 10 regarding functions associated with the area in which the sub-user exists. Then, the CPU 100 ends the process.

  In addition, although the example regarding a sub user was mainly demonstrated above, the terminal device 30 linked | related with self may be used by the main user.

  According to the above processing example (part 3), the image forming apparatus has the advantages of the processing example (part 1), and the user forms an image on the user interface screen displayed on the terminal device 30 associated with the user instead of the operation panel 170. 10 can be instructed. Therefore, the user can cause the image forming apparatus 10 to execute processing based on the detailed settings even when the operation panel 170 is not present in the area where the user exists.

(D4. Processing example (4))

  Referring to FIG. 13, CPU 100 executes the processes from steps S102 to S106. Since the processing from step S102 to S106 is the same as the processing described in the processing example (part 1), detailed description thereof will not be repeated.

  Next, the CPU 100 determines whether or not a remote panel has been detected (step S402). More specifically, CPU 100 determines whether a detection signal indicating that a remote panel has been detected has been received via sensor 192 provided in the vicinity of the area where the sub-user exists. For example, when the sub user holds the remote panel carried by himself / herself over the sensor 192, the CPU 100 determines that the remote panel has been detected.

  If the remote panel has not been detected (NO in step S402), CPU 100 repeats the process of step S402. On the other hand, when the remote panel is detected (YES in step S402), CPU 100 determines whether or not image forming apparatus 10 can execute the sub-function based on the main function (step S402). S406).

  If the CPU 100 determines that the image forming apparatus 10 cannot execute the sub function (NO in step S406), the CPU 100 executes the processes of steps S114 and S116 and ends the process. Since the process of step S114 and step S116 is the same as the process demonstrated in the process example (the 1), the detailed description is not repeated.

  In contrast, when CPU 100 determines that image forming apparatus 10 can execute the sub function (YES in step S406), CPU 100 permits the sub user to use the detected remote panel (step S406). S408). That is, the CPU 100 can accept an instruction from the user via the remote panel.

  Next, the CPU 100 transmits display data of the user interface screen corresponding to the sub function to the remote panel carried by the sub user via the panel communication unit 194 (step S410). Then, the CPU 100 causes the image forming apparatus 10 to execute processing based on the data received from the remote panel via the panel communication unit 194 (step S412). That is, the sub-user can instruct the image forming apparatus 10 regarding the function associated with the area in which the sub-user is present via the remote panel. Then, the CPU 100 ends the process.

  As described above, when a user uses a remote panel, a user ID, a password, and the like are input to the remote panel in advance, and the user is authenticated to the image forming apparatus 10 by holding the remote panel over the sensor. The form to perform may be sufficient. In addition, although the example regarding a sub user was mainly demonstrated above, the remote panel may be used by the main user.

  According to the above processing example (part 4), the image forming apparatus 10 has the advantages of the processing example (part 1) and is displayed on the user interface screen displayed on the dedicated remote panel of the image forming apparatus 10 instead of the operation panel 170. Can be instructed. Therefore, the user can cause the image forming apparatus 10 to execute processing based on the detailed settings even when the operation panel 170 is not present in the area where the user exists.
