For example, when the image output from the camera 202 includes an image on the display unit 161 of the MFP 100, the MFP 100 is detected, and the distance to the MFP 100 is calculated from the size of the image on the display unit 161. The distance acquisition unit 271 outputs a connection instruction to the first route establishment unit 273 when the distance to the MFP 100 becomes a predetermined distance or less.

  The first path establishing unit 273 controls the short-range communication unit 207 to negotiate with the MFP 100, thereby setting the communication with the MFP 100 via the wireless LAN I / F 205, and controlling the wireless LAN I / F 205. A first communication path is established with MFP 100. First path establishing unit 273 may control near field communication unit 207 or wireless LAN I / F 205 to establish the first communication path with MFP 100. First route establishment unit 273 outputs route identification information for identifying the first communication route established with MFP 100 to restriction unit 277. First route establishing section 273 receives the operation mode of MFP 100 from MFP 100, and outputs a connection instruction to second route establishment section 275 if the operation mode of MFP 100 is the power saving mode. When the operation mode of MFP 100 is the drive mode, route identification information of the first communication route is output to remote operation unit 251 in order to perform normal remote operation.

  The second path establishing unit 275 controls the wireless LAN I / F unit 205 in response to the input of the connection instruction, transmits a connection request to the server 300, and establishes the second communication path with the server 300. Establish. The connection request includes device identification information of the device to be remotely operated, here, MFP 100. The second route establishment unit 275 outputs the route identification information of the second communication route to the remote operation unit 251.

  In addition, when the second communication path is established, the second path establishment unit 275 outputs a start signal indicating that the second communication path is established to the restriction unit 277, and when the second communication path is disconnected, 2 An end signal indicating that the communication path is disconnected is output to the restriction unit 277.

  Restriction unit 277 controls wireless LAN I / F 205 to transmit a return restriction command to MFP 100 via the first communication path specified by the path identification information input from first path establishment unit 273. The return restriction command is a command that prohibits switching of the operation mode from the power saving mode to the drive mode during the first period. Restriction unit 277 transmits a return restriction command to MFP 100 at predetermined time intervals from when the start signal is input from second path establishment unit 275 to when the end signal is input. The predetermined time interval is a second period shorter than the first period.

  The remote operation unit 251 includes a remote operation screen reception unit 261 and a remote operation transmission unit 263. The remote operation screen receiving unit 261 controls the wireless LAN I / F 205 and receives a remote operation screen from the server 300 via the second communication path. The remote operation screen reception unit 261 outputs the received remote operation screen to the display control unit 253 and outputs the remote operation screen to the operation detection unit 255. The display control unit 253 controls the display unit 204 in response to the input of the remote operation screen, and displays an image of the remote operation screen on the display unit 204.

  The operation detection unit 255 controls the operation unit 206, detects a remote operation input by the user to the operation unit 206, generates a remote operation command corresponding to the detected remote operation, and remotely operates the generated remote operation command. The data is output to the transmission unit 263. When detecting a setting operation as a remote operation, the operation detection unit 255 generates a setting instruction command instructing to set setting information that defines a value corresponding to the setting item, and detects a screen transition operation as the remote operation. In this case, when a screen transition command including screen identification information is generated and an execution instruction operation is detected as a remote operation, an execution instruction command including process identification information is generated and a remote operation indicating the inside of the remote operation screen is detected. In this case, a remote operation command including position information indicating the position indicated on the remote operation screen is generated.

  When the position in the remote operation screen displayed on the display unit 204 is detected by the line-of-sight detection sensor, the operation detection unit 255 detects a remote operation instructing the remote operation screen. Further, the operation detection unit 255 detects a remote operation from the remote operation screen displayed on the display unit 204 and the position specified by the line-of-sight detection sensor included in the operation unit 206. For example, the operation detection unit 255 detects a screen transition operation when the position in the transition button included in the remote operation screen is detected by the line-of-sight detection sensor. In addition, the operation detection unit 255 detects the position in the region to which the command for setting the setting information included in the remote operation screen is assigned by the line-of-sight detection sensor in the remote operation screen displayed on the display unit 204. , Detect setting operation. The operation detection unit 255 detects an execution instruction operation when the position in the area of the button to which the execution command included in the remote operation screen is assigned in the remote operation screen displayed on the display unit 204.

  In addition, the operation detection unit 255 collects the voice uttered by the user with the microphone of the operation unit 206 and recognizes the collected voice to detect the operation by the user. For example, if a name corresponding to each of a plurality of operations is determined and a name corresponding to one of the plurality of operations exists in the character information obtained by recognizing the voice, a remote operation corresponding to the name is detected. To do. Further, the operation detection unit 255 detects character information obtained by voice recognition as setting information. For example, when the name “number of copies” is set for the setting operation for setting the number of copies, and the character string “set number of copies to 5” is recognized by voice recognition, the number of copies is set. A setting operation instructing to set setting information in which setting information “5” is associated with the setting item is detected.

  The imaging control unit 257 controls the camera 202 and acquires image data output by the camera 202 imaging the subject. The imaging control unit 257 outputs image data output from the camera 202 to the operation determination unit 259.

  The operation determination unit 259 determines an operation by the user based on the image data input from the imaging control unit 257. For example, when the display control unit 253 displays an image of the remote operation screen on the display unit 204, the display control unit 253 displays the operation panel 115 of the MFP 100 so as to overlap the display surface of the display unit 118 of the operation panel 115 of the MFP 100. It can be operated remotely as if operating. The operation determination unit 259 detects the movement of the image of the user's finger from the image data, and specifies the position in the remote operation screen from the position of the finger when the finger is stopped. Since the method for specifying the operation from the position on the remote operation screen has been described above, the description thereof will not be repeated here.

  Further, operation determination unit 259 detects an operation by the user based on a change in the shape of MFP 100. The operation determination unit 259 generates a remote operation command corresponding to the determined operation, and outputs the generated remote operation command to the remote operation transmission unit 263.

  The operations determined by the operation determination unit 259 include a configuration change operation and a process execution condition setting operation. The configuration change operation is an operation for setting setting information for determining hardware resources constituting the MFP 100. The setting information for determining the hardware resources constituting the MFP 100 includes, for example, setting information for determining the size of paper stored in a paper feed tray provided in the paper feed unit 150, and setting information for determining whether or not an optional device is installed. Including.

  The process execution condition setting operation is an operation other than the configuration change operation, and is an operation for setting setting information that determines a process that can be executed by MFP 100. The process execution condition setting operation includes an operation for selecting one of setting information set by the configuration change operation and an operation for setting setting information for determining a process to be executed by MFP 100. The operation for selecting one of setting information set by the configuration change operation is, for example, an operation for selecting one document size from among a plurality of document sizes that can be read by the MFP 100, and is stored in the paper feeding unit 150. Operation for selecting one of the plurality of sizes of paper. Further, the operation for setting the setting information for determining the processing executed by MFP 100 includes setting information for determining the number of copies to form an image.

  The operation determined by the operation determination unit 259 is the same as the operation detected by the operation detection unit 255. In other words, the operation determined by the operation determination unit 259 is an operation for setting the same setting information as the setting information set by the operation input to the operation unit 206 by the user according to the remote operation screen.

  For example, when the paper feed tray provided in the paper feed unit 150 of the MFP 100 is opened, the shape of the MFP 100 changes. The operation determining unit 259 determines a configuration change operation for determining the size of the paper stored in the paper feed tray by detecting the shape of the MFP 100 in a state where the paper feed tray is opened. More specifically, operation determination unit 259 analyzes the image data, identifies a paper feed tray included in paper feed unit 150 from the change in shape of MFP 100, and further changes in the internal shape of paper feed unit 150. The size of the paper stored in the paper feed tray is detected. When the paper feeding unit 150 includes a plurality of paper feeding trays, the operation determining unit 259 identifies a paper feeding tray that has changed to a state opened by the user from among the plurality of paper feeding trays. Further, the operation determination unit 259 detects that the size of the stored paper has been changed based on a change in the shape of the inside of the paper feed tray. Further, the operation determination unit 259 analyzes the image data after the internal shape of the paper feed tray has changed, and specifies the paper size based on the size of the paper feed tray. When the operation determining unit 259 determines the configuration change operation for determining the size of the paper stored in the paper feed tray, the size of the paper specified in the setting item for determining the size of the paper stored in the specified paper feed tray Is generated, and is output to the remote operation transmission unit 263.

  Further, when an optional device is added to the MFP 100, the shape of the MFP 100 changes. Operation determination unit 259 determines the configuration change operation that determines that an optional device has been added by detecting the shape of MFP 100 with the optional device added. The optional device is a device that can be attached to and detached from the MFP 100. For example, the optional device is a paper reversing unit that reverses the front and back of the paper supplied from the paper feeding unit 150 in order to form images on both sides of the paper. Specifically, the operation determining unit 259 analyzes the image data, and if the shape of the MFP 100 changes to the shape in which the paper reversing unit is mounted at the position where the paper reversing unit is mounted, an optional device is added. Determine the configuration change operation that determines that. When determining a configuration change operation that determines that an optional device has been added, the operation determination unit 259 associates a setting item indicating that a paper reversing unit exists with a value indicating that a paper reversing unit exists. A setting instruction command for instructing setting of setting information is generated and output to the remote operation transmission unit 263.

  Further, in MFP 100, when a document is placed on automatic document feeder 120 by the user, the shape of MFP 100 changes. The operation determination unit 259 determines a process execution condition setting operation for determining the size and direction of the document on the automatic document feeder 120 by detecting the shape of the MFP 100 in a state where the document is placed on the automatic document feeder 120. . The operation determination unit 259 specifies the size of the document based on the size of the automatic document feeder 120, and specifies the direction of the document from the specified size. When the operation determining unit 259 determines a process execution condition setting operation for determining the size and direction of the document in the automatic document feeder 120, the size and direction of the document specified from the image data in the setting item indicating the size and direction of the document. Is generated, and is output to the remote operation transmission unit 263.

  The remote operation transmission unit 263 controls the wireless LAN I / F 205 in response to the input of the remote operation command from the operation detection unit 255, and transmits the remote operation command to the server 300 via the second communication path. Further, the remote operation transmission unit 263 controls the wireless LAN I / F 205 in response to the input of the remote operation command from the operation determination unit 259, and transmits the remote operation command to the server 300 via the second communication path. .

In the remote control processing in the first embodiment, the CPU 11 provided in the MFP 100 in the first embodiment executes the remote control program in the first embodiment stored in the ROM 12, the HDD 113, or the CD-ROM 190A. Thus, the process is executed by the CPU 11. Referring to FIG. 10, CPU 11 displays an initial screen on display unit 118 (step S01). In the next step S02, it is determined whether the operation unit 119 or the sensor unit 117 has accepted an operation by the user. If the operation is accepted, the process proceeds to step S03; otherwise, the process proceeds to step S04. In step S03, the process is executed according to the accepted operation, and the process returns to step S02.

  In step S04, it is determined whether a sleep condition is satisfied. For example, in step S02, it is determined that the sleep condition is satisfied when the user's operation is not accepted for a predetermined time. If the sleep condition is satisfied, the process proceeds to step S05; otherwise, the process returns to step S02.

  In step S05, the operation mode is switched to the power saving mode. Specifically, the power supplied to the automatic document feeder 120, the document reading unit 130, the image forming unit 140, the paper feeding unit 150, and the HDD 113 is cut off. Then, the communication I / F unit 160 is controlled to transmit a proxy request to the server 300 (step S06). Then, the communication I / F unit 160 is controlled to establish a third communication path with the server 300 (step S07). In the next step S08, the setting information stored in the RAM 15 is transmitted to the server 300, and the process proceeds to step S09. Specifically, the communication I / F unit 160 is controlled to transmit the setting information to the server 300 via the third communication path established in step S07. The third communication path may be disconnected after the setting information is transmitted, or may not be disconnected.

  In step S09, it is determined whether a remote operation is requested. If the short-range communication unit 180 receives a remote operation request from the HMD 200 that is a remote operation device, it is determined that a remote operation is requested. If remote operation is requested, the process proceeds to step S10. If not, step S10 is skipped and the process proceeds to step S11. In step S10, the communication I / F unit 112 is controlled to establish a first communication path with the HMD 20, and the process is output to step S11.

  In the next step S11, it is determined whether or not a return restriction command has been received. If the communication I / F unit 160 is controlled and a return restriction command is received from the HMD 200 via the first communication path established in step S10, the process proceeds to step S12. If not, step S12 is skipped. Then, the process proceeds to step S13. In step S13, the timer is reset. The timer measures the time after receiving the return limit command. The timer value indicates the elapsed time since receiving the return restriction command.

In step S13, it is determined whether a server execution instruction is received from server 300 or not. When communication I / F unit 160 receives a server execution instruction via the third communication path established in step S07, the process proceeds to step S14; otherwise, the process proceeds to step S17. When the third communication path is disconnected, a server execution instruction is received via a communication path newly established with the server 300.

  In step S14, the operation mode is switched to the drive mode. Specifically, power is supplied to the automatic document feeder 120, the document reading unit 130, the image forming unit 140, the paper feeding unit 150, and the HDD 113.

  In the next step S15, the setting information is updated. Specifically, the setting information stored in the RAM 15 is rewritten with the setting information included in the server execution instruction received in step S14. In the next step S16, the process specified by the execution instruction command included in the server execution instruction received in step S13 is executed according to the setting information stored in the RAM 15, and the process returns to step S01.

  On the other hand, in step S17, as in step S02, it is determined whether or not an operation has been detected. If an operation is detected, the process proceeds to step S18; otherwise, the process returns to step S09. In step S18, it is determined whether or not the timer value is greater than or equal to threshold value T1. If the timer value is equal to or greater than threshold value T1, the process proceeds to step S19; otherwise, the process returns to step S09. In step S19, the operation mode is switched to the drive mode, and the process returns to step S01. Specifically, power is supplied to the automatic document feeder 120, the document reading unit 130, the image forming unit 140, the paper feeding unit 150, and the HDD 113.

  FIG. 11 is a flowchart illustrating an example of the flow of proxy processing according to the first embodiment. In the proxy processing in the first embodiment, the CPU 301 included in the server 300 in the first embodiment executes the proxy program in the first embodiment stored in the ROM 302, the HDD 304, or the CD-ROM 309. , A process executed by the CPU 301. Referring to FIG. 11, CPU 301 determines whether a proxy request has been received from MFP 100 (step S201). The process waits until the communication unit 305 receives a proxy request from the MFP 100 (NO in step S201). If a proxy request is received (YES in step S201), the process proceeds to step S202.

  In the next step S202, a third communication path is established with MFP 100 that has transmitted the proxy request, and the process proceeds to step S203. Then, the communication unit 305 is controlled to receive setting information from the MFP 100 via the third communication path established in step S202 (step S203). Then, the received setting information is stored in the HDD 304, and the process proceeds to step S205.

  In step S205, it is determined whether a connection request is received from the HMD 200 (step S205). The communication unit 305 enters a standby state until it receives a connection request from the HMD 200 (step S205). If the communication unit 305 receives a connection request (YES in step S205), the process proceeds to step S206. The connection request includes device identification information of a device that is the target of remote operation by the HMD 200. Here, a case where a connection request including apparatus identification information of MFP 100 is received will be described as an example. In step S206, the communication unit 305 is controlled to establish a second communication path with the HMD 200, and the process proceeds to step S207.

  In step S207, an initial screen is determined as a remote operation screen for transmission to the HMD 200. Specifically, a remote operation screen for remotely operating MFP 100 specified by the device identification information included in the connection request received in step S205 is determined. In the next step S208, the communication unit 305 is controlled to transmit the remote operation screen via the second communication path established in step S206. In the next step S209, it is determined whether or not a remote operation command has been received from the HMD 200. If communication unit 305 receives a remote operation command from HMD 200 via the second communication path established in step S206, the process proceeds to step S210; otherwise, the process proceeds to step S215. In step S215, it is determined whether the second communication path established with HMD 200 in step S206 has been disconnected. If the second communication path is disconnected, the process returns to step S205; otherwise, the process returns to step S209.

  In step S210, the process branches depending on the type of received remote operation command. If the remote operation command is a screen transition command, the process proceeds to step S211. If the remote operation command is a setting instruction command, the process proceeds to step S212. If the remote operation command is an execution instruction command, the process proceeds to step S213. In step S211, the remote operation screen determined by the screen transition command is determined, and the process returns to step S208. In step S208, when the process proceeds from step S211, the remote operation screen determined in step S211 is transmitted to the HMD 200 via the second communication path.

  In step S212, setting information is set according to the setting instruction command, and the process returns to step S208. Specifically, the setting information stored in the HDD 304 is updated with setting information determined by a setting instruction command. In step S208, when the process proceeds from step S212, the remote operation screen that is the same as the previously transmitted remote operation screen and has the setting information set is transmitted to the HMD 200 via the second communication path.

  In step S213, a server execution instruction is transmitted to MFP 100. The communication unit 305 is controlled to transmit a server execution instruction via the third communication path established with the MFP 100 in step S202. The server execution instruction includes setting information stored in the HDD 304 and an execution instruction command.

  In the next step S214, the communication path between the HMD 200 and the MFP 100 is disconnected, and the process ends. Specifically, the third communication path established with MFP 100 in step S202 and the second communication path established with HMD 200 in step S206 are disconnected.

  FIG. 12 is a flowchart illustrating an example of the flow of remote operation processing according to the first embodiment. The remote operation processing in the first embodiment is performed by the CPU 201 by the CPU 201 included in the HMD 200 in the first embodiment executing the remote operation program in the first embodiment stored in the flash memory 203. It is a process to be executed. Referring to FIG. 11, it is determined in step S101 whether an MFP has been detected. Specifically, when near field communication unit 207 can communicate with MFP 100, MFP 100 is detected. The process waits until MFP 100 is detected (NO in step S101). If MFP 100 is detected (YES in step S101), the process proceeds to step S102.

  In step S102, it is determined whether the distance to MFP 100 is equal to or less than threshold value L. The short-range communication unit 207 measures the distance to the MFP 100 based on the radio wave intensity received from the MFP 100. If the distance to MFP 100 is equal to or smaller than threshold value L, the process proceeds to step S103; otherwise, the process returns to step S101.

  In step S103, a first communication path is established with MFP 100. The wireless LAN I / F 205 is controlled to establish a first communication path with the MFP 100. In the next step S104, it is determined whether or not the operation mode of MFP 100 is the power saving mode. The operation mode may be inquired of the MFP 100 and the operation mode may be received from the MFP 100. If the operation mode of MFP 100 is the power saving mode, the process proceeds to step S105; otherwise, the process proceeds to step S121. In step S121, a normal remote control process is executed and the process ends. The normal remote control process is a process for remotely controlling MFP 100 when the operation mode of MFP 100 is the drive mode.

  In the next step S105, the device to be remotely operated is specified, and the process proceeds to step S106. In step S103, the MFP 100 that has established the first communication path is identified as a remote operation target device.

  In step S106, imaging by the camera 202 is started, and the process proceeds to step S107. In step S107, a connection request is transmitted to server 300. The wireless LAN I / F 205 is controlled and a connection request is transmitted to the server 300. The connection request includes device identification information for identifying the device identified in step S105, here, MFP 100.

  In step S108, the wireless LAN I / F 205 is controlled to establish a second communication path with the server 300. Then, a return restriction command is transmitted to MFP 100 (step S109). The wireless LAN I / F 205 is controlled to transmit a return restriction command via the first communication path established in step S103. In the next step S110, the timer is reset. The timer times the time since the return limit command is transmitted, and the timer value indicates the elapsed time since the return limit command is transmitted.

  In the next step S111, it is determined whether a remote operation screen has been received. It is determined whether the wireless LAN I / F 205 has received a remote operation screen from the server 300 via the second communication path established in step S108. If the remote operation screen is received, the process proceeds to step S112. If not, the process proceeds to step S120. In step S120, it is determined whether or not the second communication path established in step S108 has been disconnected. If the second communication path is disconnected, the process ends. If not, the process proceeds to step S113. When the second communication path is disconnected by an instruction from the user of the HMD 200, the communication path may be disconnected due to communication noise when the communication path is disconnected by the server 300.

  In step S112, the remote operation screen received in step S111 is displayed on display unit 204, and the process proceeds to step S113. In step S113, it is determined whether an operation has been detected. The operation here is an operation that the user inputs to the operation unit 206. For example, when the position in the remote operation screen displayed on the display unit 204 in step S112 is detected by the line-of-sight detection sensor of the operation unit 206, the operation is detected based on the remote operation screen and the detected position. . In addition, the operation unit 206 detects the operation by collecting the voice uttered by the user with the microphone of the operation unit 206 and recognizing the collected voice. If an operation is detected, the process proceeds to step S116; otherwise, the process proceeds to step S114.

  In step S114, the user's action is detected based on the image data output from the camera 202. In the next step S115, an operation by the user is determined from the detected action. If the operation by the user is determined, the process proceeds to step S116; otherwise, the process proceeds to step S111. For example, when detecting an operation by a user who opens and closes a paper feed tray included in the paper feed unit 150, a setting operation for setting setting information indicating the paper size is set in a setting item for determining the size of paper stored in the paper feed tray. decide. When analyzing the image data and specifying the paper tray and paper size, a setting operation to set the specified paper size is performed in the setting item that determines the size of the paper stored in the specified paper tray. decide. When an operation for adding an optional device is detected, a setting operation for setting setting information indicating that the optional device exists is determined in a setting item indicating that the optional device exists. The optional device is, for example, a paper reversing unit. When the user detects an operation of placing a document on the automatic document feeder 120, a setting operation for setting setting information indicating that the document is placed is set in a setting item indicating that the document is placed. decide.

  In step S116, a remote operation command is transmitted to server 300, and the process proceeds to step S117. When the process proceeds from step S113, a remote operation command corresponding to the operation detected in step S113 is generated, and the generated remote operation command is controlled by the wireless LAN I / F 205 to establish the first remote operation command established in step S108. 2 to the server 300 via the communication path. When the process proceeds from step S115, a remote operation command corresponding to the operation determined in step S115 is generated, and the generated remote operation command is controlled by the wireless LAN I / F 205, and the first remote operation command established in step S108 is established. 2 to the server 300 via the communication path.

  In step S117, it is determined whether or not the timer value is greater than or equal to threshold value T2. The threshold value T2 is a second period shorter than the first period limited by the return restriction command. If the timer value is greater than or equal to threshold value T2, the process proceeds to step S118; otherwise, the process returns to step S111.

  In step S118, similarly to step S109, the wireless LAN I / F 205 is controlled, and a return restriction command is transmitted to the MFP 100 via the first communication path. In the next step S119, similarly to step S110, the timer is reset, and the process returns to step S111.

  As described above, the MFP 100 according to the first embodiment switches the operation mode from the drive mode to the power saving mode when a predetermined sleep condition is satisfied, and an operation by the user is detected while being controlled by the HMD 200. Even in such a case, the operation mode is not switched to the drive mode. Therefore, the power consumption of MFP 100 can be reduced. On the other hand, when server 300 receives, on behalf of MFP 100, a remote operation command transmitted by HMD 200 on behalf of MFP 100, changes setting information according to the remote operation command, and receives a remote operation command corresponding to the mounting instruction operation, Since the changed setting information and the remote operation command are transmitted to the MFP 100, the HMD 200 can remotely control the MFP 100 via the server 300. Therefore, it is possible to reduce power consumption of MFP 100 while enabling remote control of MFP 100 by HMD 200.

  In addition, since the HMD 200 transmits a return restriction command for restricting the return only for the first period to the MFP 100 at the second period interval, it is possible to restrict the MFP 100 from returning to the drive mode from the HMD 200.

  Further, after switching the operation mode from the drive mode to the power saving mode, the MFP 100 is restricted by the HMD 200 and maintains the power saving mode. However, when a remote operation command corresponding to the execution instruction operation is received from the server 300, The power saving mode is switched to the operation mode. Therefore, the HMD 200 can cause the MFP 100 to execute processing.

  Further, since the HMD 200 detects an operation on the MFP 100 from an image obtained by capturing an image of the subject, the operation on the MFP 100 can be detected from outside the MFP 100, and the MFP 100 can be maintained in the power saving mode.

  Further, HMD 200 displays a remote operation screen for remotely operating MFP 100 and accepts a remote operation on the remote operation screen. Therefore, HMD 200 can accept an operation on MFP 100 from outside of MFP 100, and maintains MFP 100 in the power saving mode. be able to.

  Further, since the HMD 200 establishes a communication path with the MFP 100 when the distance to the MFP 100 becomes a predetermined value or less, an apparatus capable of remotely controlling the MFP 100 can be connected to the HMD 200 with a distance from the MFP 100 being a predetermined value or less. It can be limited to HMD200.

  Since the HMD 200 acquires the distance between the MFP 100 and the MFP 100 based on the radio field intensity that communicates wirelessly with the MFP 100, the distance between the HMD 200 and the MFP 100 can be easily acquired.

  Further, the HMD 200 acquires the distance from the MFP 100 based on the size of the image of the operation panel 115 included in the image of the image data to be improved by the camera 202 imaging the operation panel 115 as a subject. And the distance between the MFP 100 can be easily acquired.

<First Modification>
In the first embodiment described above, an example in which the remote operation device is the HMD 200 is shown, but in the first modification, the remote operation device is a PC 400.

  FIG. 13 is a block diagram illustrating an example of functions of the CPU provided in the PC according to the first modification. The functions illustrated in FIG. 13 are functions formed in the CPU 401 when the CPU 401 included in the PC 400 executes a remote operation program stored in the ROM 402, the HDD 404, or the CD-ROM 409. Referring to FIG. 13, CPU 401 remotely operates MFP 100, remote control unit 451, display control unit 453, operation reception unit 455, first route establishment unit 473, second route establishment unit 475, restriction Part 477.

  The display control unit 453 controls the display unit 406 to display an image on the display unit 406. The operation reception unit 455 controls the operation unit 407 and receives an operation input by the user to the operation unit 407.

  Remote operation unit 451 outputs a route establishment instruction to first route establishment unit 473 when operation reception unit 455 receives an instruction to remotely operate MFP 100 by the user. For example, when a remote operation activation screen is displayed on display unit 406 and the user inputs operation for designating MFP 100 as a device to be remotely operated to operation unit 407, an instruction to remotely operate MFP 100 is accepted. In this case, the route establishment instruction includes device identification information for identifying MFP 100 designated as a remote operation target by the user.

  First route establishment unit 473 establishes a first communication route with MFP 100 by controlling communication unit 405 and negotiating with MFP 100 in response to the input of a route establishment instruction. First route establishment unit 273 outputs route identification information for identifying the first communication route established with MFP 100 to restriction unit 477. First path establishment unit 473 receives the operation mode of MFP 100 from MFP 100, and outputs a connection instruction to second path establishment unit 275 if the operation mode of MFP 100 is the power saving mode. When the operation mode of MFP 100 is the drive mode, route identification information of the first communication route is output to remote operation unit 451 in order to perform normal remote operation.

  The second path establishing unit 475 controls the communication unit 405 in response to the input of the connection instruction, transmits a connection request to the server 300, and establishes the second communication path with the server 300. The connection request includes device identification information of the device to be remotely operated, here, MFP 100. The second route establishment unit 475 outputs the route identification information of the second communication route to the remote operation unit 451.

  In addition, when the second communication path is established, the second path establishment unit 475 outputs a start signal indicating that the second communication path is established to the restriction unit 477, and when the second communication path is disconnected, 2 An end signal indicating that the communication path is disconnected is output to the restriction unit 477.

  Restriction unit 477 controls communication unit 405 to transmit a return restriction command to MFP 100 via the first communication path specified by the path identification information input from first path establishment unit 473. The return restriction command is a command that prohibits switching of the operation mode from the power saving mode to the drive mode during the first period. Restriction unit 477 transmits a return restriction command to MFP 100 at predetermined time intervals from when the start signal is input from second path establishment unit 475 until the end signal is input. The predetermined time interval is a second period shorter than the first period.

  Remote operation unit 451 includes a remote operation screen reception unit 461 and a remote operation transmission unit 463. The remote operation screen receiving unit 461 controls the communication unit 405 and receives a remote operation screen from the server 300 via the second communication path. The remote operation screen receiving unit 461 outputs the received remote operation screen to the display control unit 453 and outputs the remote operation screen to the operation receiving unit 455. The display control unit 453 controls the display unit 406 in response to the input of the remote operation screen, and displays an image of the remote operation screen on the display unit 406.

  The operation reception unit 455 controls the operation unit 407, receives a remote operation input by the user to the operation unit 407, and outputs the received remote operation to the remote operation transmission unit 463. When detecting a position in the remote operation screen displayed on display unit 406, operation reception unit 455 receives a remote operation instructing the remote operation screen. Further, the operation reception unit 455 specifies a remote operation from the remote operation screen displayed on the display unit 406 and the position in the remote operation screen received by the operation unit 407. For example, the operation reception unit 455 detects a screen transition operation when a position in a transition button included in the remote operation screen is received. The operation accepting unit 455 accepts a setting operation when a position in an area to which a command for setting setting information included in the remote operation screen is assigned in the remote operation screen displayed on the display unit 406 is accepted. . The operation accepting unit 455 accepts an execution instruction operation when the position in the area of the button to which the execution command included in the remote operation screen is assigned in the remote operation screen displayed on the display unit 406.

  The remote operation transmission unit 463 generates a remote operation command corresponding to the remote operation input from the operation reception unit 455. When the remote operation transmission unit 463 detects a setting operation as a remote operation, the remote operation transmission unit 463 generates a setting instruction command instructing to set setting information that defines a value corresponding to the setting item, and detects a screen transition operation as the remote operation If a screen transition command including screen identification information is generated and an execution instruction operation is detected as a remote operation, an execution instruction command including process identification information is generated and a remote operation indicating the remote operation screen is detected. If so, a remote operation command including position information indicating the position indicated on the remote operation screen is generated. The remote operation transmission unit 263 controls the communication unit 405 and transmits a remote operation command to the server 300 via the second communication path.

  FIG. 14 is a flowchart illustrating an example of the flow of remote operation processing in the first modification. The remote operation process in the first modification is a process executed by the CPU 401 when the CPU 401 included in the PC 400 in the first modification executes a remote operation program stored in the ROM 402, the HDD 404, or the CD-ROM 409. is there. Referring to FIG. 14, the difference from the remote operation processing shown in FIG. 12 is that step S101A is executed instead of step S101 and step S102, step S106, step S114 and step S115 are deleted, Step S113 is changed to step S113A. Other processes are the same as those shown in FIG.

  The CPU 401 determines whether a remote operation instruction has been accepted. The operation unit 407 is in a standby state until accepting a remote operation instruction (NO in step S101A). If a remote operation instruction is accepted (YES in step S101A), the process proceeds to step S103. The remote operation instruction includes an instruction for specifying a device to be remotely operated. Here, a case will be described as an example where MFP 100 is specified as a device to be remotely operated.

  In step S103, a first communication path is established with MFP 100. The communication unit 405 is controlled to establish a first communication path with the MFP 100. In the next step S104, it is determined whether or not the operation mode of MFP 100 is the power saving mode. The operation mode may be inquired of the MFP 100 and the operation mode may be received from the MFP 100. If the operation mode of MFP 100 is the power saving mode, the process proceeds to step S105; otherwise, the process proceeds to step S121. In step S121, a normal remote control process is executed and the process ends. The normal remote control process is a process for remotely controlling MFP 100 when the operation mode of MFP 100 is the drive mode. In step S105, a device to be remotely operated is specified, and the process proceeds to step S107. In step S103, the MFP 100 that has established the first communication path is specified.

  In step S107, a connection request is transmitted to server 300. The communication unit 405 is controlled and a connection request is transmitted to the server 300. The connection request includes device identification information for identifying the device identified in step S105, here, MFP 100.

  In step S108, the communication unit 405 is controlled to establish a second communication path with the server 300. Then, a return restriction command is transmitted to MFP 100 (step S109). The communication unit 405 is controlled to transmit a return restriction command via the first communication path established in step S103. In the next step S110, the timer is reset.

  In the next step S111, it is determined whether a remote operation screen has been received. It is determined whether or not communication unit 405 has received a remote operation screen from server 300 via the second communication path established in step S108. If the remote operation screen is received, the process proceeds to step S112. If not, the process proceeds to step S120. In step S120, it is determined whether or not the second communication path established in step S108 has been disconnected. If the second communication path is disconnected, the process ends. If not, the process proceeds to step S113.

  In step S112, the remote operation screen received in step S111 is displayed on display unit 406, and the process proceeds to step S113A. In step S113A, it is determined whether an operation has been accepted. If an operation is accepted, the process proceeds to step S116; otherwise, step S116 is skipped and the process proceeds to step S117. In step S116, a remote operation command is transmitted to server 300, and the process proceeds to step S117. A remote operation command corresponding to the operation accepted in step S113A is generated, and the generated remote operation command is transmitted to the server 300 via the second communication path established in step S108 by controlling the communication unit 405. .

  In step S117, it is determined whether the timer value is equal to or less than threshold value T2. The threshold value T2 is a second period shorter than the first period limited by the return restriction command. If the timer value is equal to or smaller than threshold value T2, the process proceeds to step S118. If not, the process returns to step S111.

  In step S118, similarly to step S109, the wireless LAN I / F 205 is controlled, and a return restriction command is transmitted to the MFP 100 via the first communication path. In the next step S119, similarly to step S110, the timer is reset, and the process returns to step S111.

  In the image forming system in the first modified example, when user B, who is different from user A, operates MFP 100 while user A operates PC 400 to remotely operate MFP 100, the operation mode of MFP 100 is In the power saving mode, the MFP 100 does not accept the operation of the user B and does not switch the operation mode to the driving mode. In addition to the operation input to the operation unit 119, the operation by the user B is an operation for opening and closing the automatic document feeder 129, an operation for placing a document on the automatic document feeder 129, and an operation for opening and closing the paper feed tray of the paper feeder 150. And an operation for opening and closing the front door 140A.

<Second Modification>
In the first embodiment described above, the HMD 200 controls the MFP 100 not to switch the operation mode to the drive mode by transmitting a return restriction command to the MFP 100. In the second modification, when MFP 100 requests permission from HMD 200 and HMD permits, MFP 100 switches the operation mode to the drive mode, and when HMD 200 does not permit, MFP 100 does not switch the operation mode to the drive mode. To control.

  FIG. 15 is a block diagram illustrating an example of a configuration of a main board included in the MFP according to the second modification. Referring to FIG. 15, the function of CPU 11 shown in FIG. 7 is different from that of command receiver 63 in that command receiver 63 is deleted, permission receiver 81 and permission request unit 83 are added, and return unit 55 is different. This is a change to the return unit 55A. Other functions are the same as the functions shown in FIG. 7, and thus description thereof will not be repeated here.

  The permission request unit 83 controls the short-range communication unit 180 and the communication I / F unit 160 to establish a first communication path with the remote control device. Here, the remote control device is HMD200. For example, when the short-range communication unit 180 can communicate with the HMD 200, the permission request unit 83 receives a remote operation request from the HMD 200 and establishes a first communication path with the HMD 200 via the communication I / F unit 160. To do. The permission request unit 83 performs settings for communicating with the HMD 200 via the communication I / F unit 160 by negotiating with the HMD 200 when the short-range communication unit 180 becomes communicable with the HMD 200, and the communication I / F unit 160. To establish a first communication path with the HMD 200. Note that the permission request unit 83 may control only one of the short-range communication unit 180 and the communication I / F unit 160 to establish the first communication path.

  When the operation mode is switched to the power saving mode, the permission request unit 83 sends a permission request signal requesting permission to the HMD 200 to the communication I / F unit 160 when an operation by the user is detected by the operation detection unit 61. Is transmitted via the first communication path.

  The permission receiving unit 81 controls the communication I / F unit 160 after the permission request unit 83 transmits the permission request signal, and outputs a permission signal to the return unit 55A when receiving the permission signal from the HMD 200.

  When the operation mode is switched to the power saving mode, the return unit 55A responds to the operation detection signal input from the operation detection unit 61 on the condition that the permission signal is input from the permission reception unit 81. The operation mode is switched from the power saving mode to the drive mode.

  When the operation mode is switched to the power saving mode, the return unit 55A changes the operation mode from the power saving mode even when the operation detection signal is input from the operation detection unit 61 when the permission signal is not input from the permission reception unit 81. Do not switch to drive mode.

  MFP 100 in the second modified example requests permission from HMD 200 when an operation is detected in a state where the operation mode is switched to the power saving mode, and HMD 200 requests MFP 100 via server 300. During the remote control, even if permission is requested from the MFP 100, the permission is not permitted, so that the MFP 100 can be restricted from returning to the drive mode from the HMD 200.

  Further, after the operation mode is switched from the drive mode to the power saving mode, the MFP 100 in the second modification example is limited by the remote operation device and maintains the power saving mode, but corresponds to the execution instruction operation from the server 300. When the remote operation command is received, the power saving mode is switched to the operation mode. Therefore, the HMD 200 can cause the MFP 100 to execute processing.

<Third Modification>
The permission receiving unit 81 and the permission request unit 83 included in the CPU 11 included in the MFP 100 according to the second modification may be added to the function of the CPU 11 included in the MFP 100 according to the first embodiment. In this case, when the operation mode is switched to the power saving mode, the return unit 55 receives a return limit signal from the command reception unit 63 in response to the operation detection signal input from the operation detection unit 61. The operation mode is switched from the power saving mode to the drive mode on the condition that the first period has elapsed since the first period, but the first period has not elapsed since the return limiting signal was input from the command receiving unit 63. Even when the permission signal is input from the permission receiver 81, the operation mode is switched from the power saving mode to the driving mode. For example, when the second communication path established between the HMD 200 and the server 300 is disconnected before the first period elapses, the MFP 100 switches the operation mode to the drive mode. In addition, the first period determined by the return restriction command can be lengthened, and the number of times the return restriction command is transmitted can be reduced.

<Second Embodiment>
The image forming system 1 in the second embodiment is configured such that the MFP 100 has the functions of the server 300 in the first embodiment. The hardware configurations of the HMD 200 and the MFP 100 in the second embodiment are the same as the hardware configurations shown in FIG. The appearance and hardware configuration of the MFP in the second embodiment are the same as the appearance and hardware configuration of the MFP in the first embodiment shown in FIGS. 3 and 4. Therefore, description is not repeated here.

  FIG. 16 is a block diagram illustrating an example of a configuration of a main board included in the MFP according to the second embodiment. Referring to FIG. 16, the configuration of main board 110 provided in MFP 100 in the first embodiment shown in FIG. 7 is different from that of CPU 11 in the functions of CPU 11 in remote control unit 53, return unit 55, and setting unit 57. The processing execution unit 59 is changed to a remote control unit 53B, a return unit 55B, a setting unit 57B, and a processing execution unit 59B. Other functions are the same as the functions shown in FIG. 7, and thus description thereof will not be repeated here.

  The remote control unit 53B receives from the command receiving unit 63 the path identification information of the first communication path established with the remote control device by the command receiving unit 63. Remote control unit 53B includes a remote operation reception unit 91 and a remote operation screen transmission unit 93. When the first communication path is established with the HMD 200, the remote operation screen transmission unit 93 reads a default remote operation screen as an initial screen from the HDD 113, and displays the read remote operation screen as a communication I / F. The control unit 160 is controlled and transmitted to the HMD 200, and a remote operation screen is output to the remote operation reception unit 91.

  The remote operation receiving unit 91 controls the communication I / F unit 160 and receives a remote operation command transmitted from the HMD 200. In response to receiving the remote operation command from the remote operation device, the remote operation reception unit 91 outputs the remote operation command to the remote operation screen transmission unit 93, the return unit 55B, the setting unit 57B, and the process execution unit 59B. .

  When a remote operation command is input from the remote operation receiving unit 91, the remote operation screen transmission unit 93 generates a remote operation screen corresponding to the remote operation command, and the generated remote operation screen is transmitted to the communication I / F unit 160. It controls and transmits to HMD200.

  The remote operation command transmitted to the MFP 100 by the HMD 200 as the remote operation device includes a setting instruction command corresponding to a setting operation for setting setting information and a screen transition operation instructing switching of the remote operation screen to another remote operation screen. A corresponding screen transition command, and an execution instruction command corresponding to an execution instruction operation for instructing execution of the process. The setting instruction command defines setting items and setting information. The screen transition command includes screen identification information for identifying the remote operation screen. The execution instruction command includes process identification information for identifying a process.

  The remote operation command transmitted to the MFP 100 by the HMD 200 that is a remote operation device may include position information indicating a position in the remote operation screen. When the remote operation command received after the remote operation screen is transmitted includes position information, the remote operation reception unit 91 includes the position information and the remote operation screen transmitted to the remote operation device by the remote operation screen transmission unit 93. Based on the command, a setting instruction command, a screen transition command, or an execution instruction command is generated, and the generated setting instruction command, screen transition command, or execution instruction command is transmitted to the remote operation screen transmission unit 93, the return unit 55, and the setting unit. 57 and the process execution unit 59. Specifically, if the position specified in the remote operation screen by the position information is within a transition button included in the remote operation screen, the screen transition operation is specified, and a screen transition command corresponding to the specified screen transition operation is specified. Generate. If the position specified on the remote operation screen by the position information is within an area to which a command for setting a setting value is assigned, the setting instruction operation is specified, and a setting command corresponding to the specified setting instruction operation is generated. If the position specified in the remote operation screen by the position information is within the area of the button to which the execution command is assigned, the execution instruction operation is specified, and an execution instruction command corresponding to the specified execution instruction operation is generated.

  When the setting instruction command is input from the remote operation receiving unit 91, the setting unit 57B sets the setting information according to the setting instruction command. The setting unit 57B sets the setting information determined by the setting instruction command to the setting item determined by the setting instruction command. Specifically, among the setting information stored in the RAM 13, the setting information of the setting item determined by the setting command is updated with the setting information determined by the setting command.

  When a setting instruction is input from the operation detection unit 61, the setting unit 57B sets setting information according to the setting instruction. The setting unit 57B sets the setting information included in the setting instruction to the setting item included in the setting instruction. Specifically, of the setting information stored in the RAM 13, the setting information of the setting item determined by the setting instruction is updated with the setting information determined by the setting instruction.

  When the operation mode is switched to the power saving mode, when the operation detection signal is input from the operation detection unit 61, the return unit 55B has a first period after the return limit signal is input from the command reception unit 63. The operation mode is switched from the power saving mode to the drive mode on condition that the time has elapsed. Specifically, the return unit 55B supplies power to the automatic document feeder 120, the document reading unit 130, the image forming unit 140, the paper feeding unit 150, and the HDD 113. The return unit 55B is a case where the operation mode is switched to the power saving mode, and when the first period has not elapsed since the return limit signal was input from the command receiving unit 63, the operation detection unit 61 The operation mode is not switched from the power saving mode to the drive mode even if the operation detection signal is input from.

  The return unit 55B is a remote operation receiving unit when the operation mode is switched to the power saving mode and the first period has not elapsed since the return limit signal was input from the command receiving unit 63. An execution instruction command may be input from 91. The return unit 55B is remote-controlled even when the operation mode is switched to the power saving mode and the first period has not elapsed since the return limit signal was input from the command receiving unit 63. The operation mode is switched to the drive mode in response to the execution instruction command input from the reception unit 91.

  The process execution unit 59B performs the process specified by the process identification information included in the execution instruction in response to the execution instruction being input from the operation detection unit 61 while the operation mode is switched to the drive mode. This is executed according to the setting information set by the setting unit 57B. Specifically, the process execution unit 59B reads the setting information stored in the RAM 13, and executes the process according to the read setting information. The processing executed by the processing execution unit 59B controls the automatic document feeder 120 and the document reading unit 130 to scan a document, and controls the image forming unit 140 and the paper feeding unit 150 to form an image on a sheet. An image forming process, a data management process including a process for controlling the HDD 113 to write data to the HDD 113 and a process for reading the data stored in the HDD 113, a data transmission process for controlling the communication I / F unit 160 to transmit data, Or the process which combined 2 or more of these processes is included. When the execution instruction is input from the operation detection unit 61 while the operation mode is switched to the power saving mode by the sleep transition unit 51B, the processing execution unit 59B is switched to the drive mode by the return unit 55B. Therefore, the process execution unit 59B does not execute the process.

  Further, when the execution mode command is input from the remote operation receiving unit 91 in a state where the operation mode is switched to the power saving mode by the sleep transition unit 51B, the processing execution unit 59B drives the operation mode by the return unit 55B. Since the mode is switched, the process execution unit 59B executes the process determined by the execution instruction command. In the state where the operation mode is switched to the power saving mode, when the execution instruction command is input from the remote operation receiving unit 91, the operation mode is switched to the drive mode by the return unit 55B. Processing for controlling the reading unit 130, the image forming unit 140, the paper feeding unit 150, and the HDD 113 can be executed.

  FIG. 17 is a block diagram illustrating an example of an overview of the functions of the CPU provided in the HMD according to the second embodiment. The functions shown in FIG. 17 are different from the functions shown in FIG. 9 in that the second route establishment unit 275 is deleted and the remote operation unit 251 is changed to the remote operation unit 251A. Other functions are the same as those shown in FIG. 9, and therefore, description thereof will not be repeated here.

  Remote operation unit 251A receives the route identification information of the first communication route established with MFP 100 by first route establishing unit 273. The remote operation unit 251A includes a remote operation screen reception unit 261A and a remote operation transmission unit 263A. Remote operation screen receiving unit 261A controls wireless LAN I / F 205 and receives a remote operation screen from MFP 100 via the first communication path. The remote operation screen receiving unit 261A outputs the received remote operation screen to the display control unit 253 and outputs the remote operation screen to the operation detection unit 255.

  Remote operation transmission unit 263A controls wireless LAN I / F 205 in response to a remote operation command input from operation detection unit 255, and transmits the remote operation command to MFP 100 via the first communication path. Remote operation transmission unit 263A controls wireless LAN I / F 205 in response to a remote operation command input from operation determination unit 259, and transmits the remote operation command to MFP 100 via the first communication path.

  18 and 19 are flowcharts illustrating an example of the flow of remote control processing in the second embodiment. In the remote control processing in the second embodiment, the CPU 11 provided in the MFP 100 in the second embodiment executes the remote control program in the first embodiment stored in the ROM 12, the HDD 113, or the CD-ROM 190A. Thus, the process is executed by the CPU 11. Referring to FIGS. 18 and 19, the processing from step S01 to step S05 is the same as the processing from step S01 to step S05 shown in FIG. Therefore, the description will not be repeated here. If it is determined in step S04 that the sleep condition is satisfied and the mode is switched to the power saving mode in step S05, the process proceeds to step S21.

  In step S21, it is determined whether a connection request has been received. If the short-range communication unit 180 has received a connection request, the process proceeds to step S24. If not, the process proceeds to step S22. It is determined whether the short-range communication unit 180 has received a connection request from the HMD 200 that is a remote control device.

  In step S22, it is determined whether an operation by the user is accepted. If operation unit 119 or sensor unit 117 detects an operation by the user, the process proceeds to step S23. If not, the process returns to step S21. In step S23, the operation mode is switched to the drive mode, and the process returns to step S02. Specifically, power is supplied to the automatic document feeder 120, the document reading unit 130, the image forming unit 140, the paper feeding unit 150, and the HDD 113.

  When the process proceeds to step S24, a connection request is received from the remote control device. Here, a case where a connection request is received from the HMD 200 will be described as an example. In step S24, the communication I / F unit 160 is controlled to establish a first communication path with the HMD 200, and the process proceeds to step S25.

  In step S25, an initial screen is determined as a remote operation screen for transmission to the HMD 200. In the next step S26, the communication I / F unit 160 is controlled to transmit the remote operation screen via the first communication path established in step S24.

  In the next step S27, it is determined whether or not a return restriction command has been received from the HMD 200. If communication I / F unit 160 receives a return restriction command from HMD 200 via the first communication path, the process proceeds to step S28; otherwise, step S28 is skipped and the process proceeds to step S29. In step S28, the timer is reset, and the process proceeds to step S29. The timer measures the time after receiving the return limit command. The timer value indicates the elapsed time since receiving the return restriction command.

  In step S29, it is determined whether or not the first communication path established in step S24 has been disconnected. If the first communication path is disconnected, the process returns to step S21; otherwise, the process proceeds to step S30. In step S30, as in step S22, it is determined whether or not an operation by the user has been accepted. If the operation is accepted, the process proceeds to step S31; otherwise, the process proceeds to step S33.

  In step S31, it is determined whether or not the timer value is greater than or equal to threshold value T1. If the timer value is greater than or equal to threshold value T1, the process proceeds to step S32. If not, the process proceeds to step S33. In step S32, the operation mode is switched to the drive mode, and the process returns to step S01. Specifically, power is supplied to the automatic document feeder 120, the document reading unit 130, the image forming unit 140, the paper feeding unit 150, and the HDD 113.

  In step S33, it is determined whether a remote operation command has been received from HMD 200. If communication I / F unit 160 receives a remote operation command via the first communication path established in step S24, the process proceeds to step S34. If not, the process returns to step S27.

  In step S34, the process branches depending on the type of received remote operation command. If the remote operation command is a screen transition command, the process proceeds to step S35. If the remote operation command is a setting instruction command, the process proceeds to step S36. If the remote operation command is an execution instruction command, the process proceeds to step S37. In step S35, a remote operation screen determined by the screen transition command is determined, and the process proceeds to step S41. In step S41, when the process proceeds from step S35, the remote operation screen determined in step S35 is transmitted to the HMD 200. The communication I / F unit 112 is controlled to transmit a remote operation screen via the first communication path.

  In step S36, setting information is set according to the setting instruction command, and the process proceeds to step S41. Specifically, the setting information stored in the RAM 13 is updated with setting information determined by a setting instruction command. In step S41, when the process proceeds from step S36, the communication I / F unit 112 is controlled with the remote operation screen that is the same as the previously transmitted remote operation screen and the setting information is set. To the HMD 200 via the first communication path.

  In step S37, the operation mode is switched to the drive mode, and the process proceeds to step S38. Power is supplied to the automatic document feeder 120, the document reading unit 130, the image forming unit 140, the paper feeding unit 150, and the HDD 113. Then, the process determined by the execution instruction command is executed according to the setting information stored in the RAM 13 (step S38), and the process proceeds to step S39.

  In step S39, as in step S05, the operation mode is switched to the power saving mode, and the process proceeds to step S40. In step S40, a remote operation screen is determined, and the process proceeds to step S41. For example, the remote operation screen including the result of executing the process is determined. In step S41, when the process proceeds from step S40, the remote operation screen determined in step S40 is transmitted to the HMD 200 via the first communication path by controlling the communication I / F unit 112.

  FIG. 20 is a flowchart illustrating an example of the flow of remote operation processing according to the second embodiment. The remote operation processing in the second embodiment is performed by the CPU 201 by the CPU 201 included in the HMD 200 in the second embodiment executing the remote operation program in the second embodiment stored in the flash memory 203. It is a process to be executed. Referring to FIG. 20, the difference from the remote operation processing in the first embodiment shown in FIG. 12 is that step S107 and step S108 are deleted, and step S111, step S116 and step S120 are different from step S111A. , Step S116A and Step S120A. Other processes are the same as those shown in FIG. Therefore, description is not repeated here.

  The CPU 201 provided in the HMD 200 in the second embodiment does not execute the step S107 and the step S108 of the remote operation process in the first embodiment shown in FIG. Do not establish.

  In step S111A, it is determined whether a remote operation screen has been received. It is determined whether or not wireless LAN I / F 205 has received a remote operation screen from MFP 100 via the first communication path established in step S103. If the remote operation screen is received, the process proceeds to step S112. If not, the process proceeds to step S120.

  In step S116A, a remote operation command is transmitted to MFP 100, and the process proceeds to step S117. When the process proceeds from step S113, a remote operation command corresponding to the operation detected in step S113 is generated, and the generated remote operation command is controlled by the wireless LAN I / F 205, and the first remote operation command established in step S103 is established. It transmits to MFP 100 via one communication path. When the process proceeds from step S115, a remote operation command corresponding to the operation determined in step S115 is generated, and the generated remote operation command is controlled by the wireless LAN I / F 205, and the first remote operation command established in step S103 is established. It transmits to MFP 100 via one communication path.

  In step S120A, it is determined whether or not the first communication path established in step S103 has been disconnected. If the first communication path is disconnected, the process ends. If not, the process proceeds to step S113.

  As described above, MFP 100 according to the second embodiment switches the operation mode from the drive mode to the power saving mode when a predetermined sleep condition is satisfied, and an operation by the user is detected while being restricted by HMD 200. Even in this case, the setting information is set according to the remote operation command received from the HMD 200 without switching the operation mode to the drive mode. Therefore, while being restricted by the HMD 200, the setting information can be set by being remotely operated by the HMD 200 without switching to the drive mode even when an operation by the user is accepted. As a result, the power consumption mode can be reduced by making the MFP 100 as long as possible in the power saving mode.

  In addition, since the HMD 200 in the second embodiment transmits a return restriction command that restricts the return only for the first period at the second period interval, the HMD 200 may restrict the MFP 100 from returning to the drive mode. it can.

  Further, after switching the operation mode from the drive mode to the power saving mode, the MFP 100 is restricted by the HMD 200 and maintains the power saving mode. However, when receiving a remote operation command corresponding to the execution instruction operation from the HMD 200, the MFP 100 saves power. Switch the mode to operating mode. Therefore, the HMD 200 can cause the MFP 100 to execute processing.

<Fourth Modification>
In the fourth modification example of the second embodiment, the remote control device is a PC 400 as in the first modification example of the first embodiment. In this case, unlike PC 400 in the first modification, PC 400 is remote from MFP 100 via the first communication path established with MFP 100 without establishing a second communication path with server 300. The operation screen is received and a remote operation command is transmitted to MFP 100.

  Therefore, when user A operates user PC 400 to remotely operate MFP 100 and user B different from user A operates MFP 100, MFP 100 operates in the power saving mode, MFP 100 Does not accept the operation of user B and does not switch the operation mode to the drive mode. In addition to the operation input to the operation unit 119, the operation by the user B is an operation of opening and closing the automatic document feeder 129, an operation of placing a document on the automatic document feeder 129, and an operation of opening and closing the paper feed tray of the paper feeder 150 And an operation for opening and closing the front door 140A.

<Fifth Modification>
The fifth modification example of the second embodiment is similar to the second modification example of the first embodiment. When the MFP 100 requests permission from the HMD 200 and the HMD permits, the MFP 100 operates in the operation mode. When the HMD 200 does not permit, the MFP 100 performs control so that the operation mode is not switched to the drive mode.

  Specifically, in the function of CPU 11 provided in MFP 100 in the second embodiment shown in FIG. 16, instead of command receiving unit 63, permission receiving unit 81 in the second modification of the first embodiment is used. And the permission request | requirement part 83 is added.

  MFP 100 in the fifth modified example requests permission from HMD 200 in response to detection of an operation in the state where the operation mode is switched to the power saving mode, and HMD 200 performs remote control corresponding to the execution instruction operation. Until the operation command is transmitted, even if permission is requested from the MFP 100, permission is not permitted. Therefore, it is possible to restrict the MFP 100 from returning to the drive mode from the HMD 200.

  Further, after switching the operation mode from the drive mode to the power saving mode, the MFP 100 is restricted by the HMD 200 and maintains the power saving mode. However, when a remote operation command corresponding to the execution instruction operation is received from the HMD 200, Switch the power saving mode to the operation mode. Therefore, the HMD 200 can cause the MFP 100 to execute processing.

<Sixth Modification>
The permission receiving unit 81 and the permission request unit 83 included in the CPU 11 of the MFP 100 according to the second modification example of the first embodiment may be added to the function of the CPU 11 of the MFP 100 according to the second embodiment. . In this case, when the operation mode is switched to the power saving mode, the return unit 55 receives a return limit signal from the command reception unit 63 in response to the operation detection signal input from the operation detection unit 61. The operation mode is switched from the power saving mode to the drive mode on the condition that the first period has elapsed since the first period, but the first period has not elapsed since the return limiting signal was input from the command receiving unit 63. Even when the permission signal is input from the permission receiver 81, the operation mode is switched from the power saving mode to the driving mode. In this case, the first period determined by the return restriction command can be lengthened, and the number of times the return restriction command is transmitted can be reduced.

  Note that the MFP 100 according to the second embodiment includes the CPU 11, and the CPU 11 is driven even when the operation modes are the power saving mode and the drive mode. The CPU 11 may be composed of a main CPU and a sub CPU that consumes less power than the main CPU. In this case, when the operation mode is the drive mode, the main CPU is driven and the sub CPU is stopped, and when the operation mode is the power saving mode, the sub CPU is driven and the main CPU is stopped. When the operation mode is the power saving mode, the sub CPU communicates with the HMD 200 via the first communication path established with the HMD 200 that is a remote operation device, transmits a remote operation screen, and performs remote operation. Executes the process of receiving commands. Thereby, the power consumption when the operation mode is the power saving mode can be further reduced.

  Further, when the operation mode is the power saving mode, a main RAM used as a work area of the main CPU and a sub RAM that consumes less power than the main RAM and is used as a work area of the sub CPU are provided. Drives the sub CPU and the sub RAM, stops the main CPU and the main RAM, and when the operation mode is the drive mode, drives the main CPU and the main RAM and stops the sub CPU and the sub RAM. Good. In this case, power consumption when the operation mode is the power saving mode can be further reduced. When the operation mode is switched from the drive mode to the power saving mode, the setting information is transferred from the main RAM to the sub RAM. When the operation mode is switched from the power saving mode to the drive mode, the setting information is transferred from the sub RAM. It must be transferred to the main RAM.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
