Description

  The present invention relates to an information processing apparatus that performs image processing.

  In recent years, mobile terminals such as smartphones and tablets have become widespread. Because it is relatively low-priced and small and portable, each person often carries it at all times. It is managed by each person. The mobile terminal has a communication function and various sensors, and is multifunctional and highly functional. It is used on a daily basis and users are accustomed to operating mobile terminals.

  A technique for improving convenience such as operability of a multifunction peripheral by utilizing such characteristics of a mobile terminal has been proposed. For example, the multifunction device described in Patent Document 1 detects that the mobile terminal is placed on the multifunction device, acquires posture information of the mobile terminal via the communication function, and determines an operation mode based on the posture information. .

  Specifically, if the display information of the mobile terminal is orientation information facing the mounting surface of the multifunction device, the printing mode is determined, and the display display of the mobile terminal is in the same direction as the mounting surface of the multifunction device. If it is attitude information, the data transfer mode is determined. The user can print without operating the multifunction device. This improves the operability of the multifunction device.

  The operation / display panel 3 is a user interface, displays operation information, and inputs a user command to the main controller 10. A touch panel in which a display function and an operation input function are integrated is preferable, but the display function and the operation input function may be separate.

  The image reading device 4 receives an original table for positioning an original, a scanning drive system that scans an image of the original placed on the original table and emits light, and light reflected or transmitted by scanning of the scan driving system. And a photoelectric conversion element such as a CCD for converting into an electrical signal. Image data is acquired based on a command from the main controller 10 and output to the main controller 10.

  The image forming apparatus 5 is formed by scanning exposure by a photosensitive member, a charging device that uniformly charges the photosensitive member, a scanning exposure unit that scans a light beam based on image data, and a scanning exposure unit. An image developing unit that develops the electrostatic latent image, a transfer unit that transfers the developed image on the photoconductor to the recording paper, a cleaning unit that cleans the surface of the photoconductor after the transfer, and a conveyance path for the recording paper And a fixing unit for fixing the image on the recording paper after the transfer. Based on a command from the main control device 10, image data acquired from the outside via the communication device 7 or image data acquired by the image reading device 4 is formed as an image on a recording sheet.

  The facsimile communication device 6 is connected to a telephone line network and executes facsimile reception and facsimile transmission.

  The communication device 7 is connected to a network line, and performs input / output of information with the outside based on a command from the main control device 10.

  The main control device 10 is connected to each device via a bus (shown by a solid line) and controls each device.

  In the present embodiment, the multifunction device 1 can communicate with the mobile terminal 20 such as a smartphone or a tablet. Data communication is performed via a router via a network line, and direct communication is performed using near field communication (NFC). That is, the communication device 7 performs short-range wireless communication. One example of near field communication is BLUETOOTH (registered trademark).

  The multifunction device 1 includes an antenna 8. The multifunction device 1 measures the strength (electric field strength) of radio waves (short-range wireless communication) received from the mobile terminal 20 via the antenna 8.

  FIG. 2 is a schematic configuration diagram of the mobile terminal 20 and a functional block diagram of the main control unit 10 of the multifunction machine 1.

  First, a schematic configuration of the mobile terminal 20 will be described. For example, the mobile terminal 20 is a smartphone or a tablet. The mobile terminal 20 includes a communication unit 21, a display 22, and a control unit 23.

  The communication unit 21 can communicate with the multifunction device 1. Data communication is performed through a network line via a router, and direct communication is performed through short-range wireless communication.

  The display 22 is preferably a touch panel. The control unit 23 operates the stored program and performs various controls. At that time, various information is displayed on the display 22.

  The mobile terminal 20 is equipped with various sensors such as an acceleration sensor 24 and a brightness sensor 25. Many programs (applications) 26 stored in the mobile terminal 20 operate based on information acquired from various sensors. Various sensors will be described in detail in the third embodiment.

  Next, a functional block diagram of the main control unit 10 of the multifunction machine 1 will be described. Characteristic relationships between the main control units are indicated by arrows.

  The main control unit 10 includes an ID verification unit 11, a use permission unit 12, a power supply control unit 13, a panel control unit 14, an image reading control unit 15, an image formation control unit 16, and a facsimile communication control unit 17.

  The ID collation unit 11 collates the user ID and password input via the operation / display panel 3 with the user ID and password stored in the storage unit 19. Based on the collation match in the ID collation unit 11, the use permission unit 12 considers that the user is permitted to use the multifunction device 1 and grants the use permission. That is, the subsequent operation is performed assuming that the user has been authenticated.

  The power supply control unit 13 controls the power supply device 2. In particular, if it is determined to shift from the start mode to the sleep mode according to a predetermined condition, the power supplied to each device is reduced. The power supply can be controlled individually for each device. For example, when printing, the sleep state of the image forming apparatus 5 can be canceled while the sleep state of the image reading apparatus 4 is maintained.

  Note that a print request and a facsimile reception request can be received at any time, thereby canceling the sleep state related to the corresponding device.

  Further, power is always supplied to the communication device 7 (especially a communication unit related to short-range wireless communication). Short-range wireless communication consumes less power and meets energy-saving requirements even when it is always on.

  The panel control unit 14 controls the operation / display panel 3. The image reading control unit 15 controls the image reading device 4. The image forming control unit 16 controls the image forming apparatus 5. The facsimile communication control unit 17 controls the facsimile communication device 6. The communication control unit 18 controls the communication device 7.

  The storage unit 19 is, for example, a nonvolatile memory such as a flash memory or a hard disk drive. Information such as user ID and password is stored.

  In the present embodiment, the main control unit 10 includes a received electric field strength measurement unit 31, a mobile terminal first approach detection unit 32, a mobile terminal verification unit 33, and a mobile terminal second approach detection unit 35. .

  The received electric field strength measuring unit 31 measures the received electric field strength of radio waves (particularly, radio waves related to short-range wireless communication) received from the antenna 8 from the mobile terminal 20.

  The mobile terminal first approach detection unit 32 detects that the mobile terminal 20 has approached a predetermined distance from the multifunction machine 1 (first approach state) (details will be described later, see description corresponding to FIG. 5).

  The mobile terminal verification unit 33 acquires the identifier of the mobile terminal 20 through communication with the mobile terminal 20 and verifies the acquired mobile terminal identifier with the mobile terminal identifier stored in the storage unit 19.

  The mobile terminal second approach detection unit 35 detects that the mobile terminal 20 has approached the multifunction device 1 from the first approach state and stopped moving within the operable range of the multifunction device 1 (second approach state). (See description corresponding to FIG. 5).

  In addition, after detecting the second approach state, the use permission unit 12 considers that the user is permitted to use the multifunction device 1 based on the collation coincidence in the mobile terminal collation unit 33, and permits the use. (See arrow shown). The storage unit 19 stores an identifier unique to the mobile terminal corresponding to the mobile terminal 20 to which the access right is given.

  Further, the storage unit 19 may store the user ID and password in association with the mobile terminal identifier, and the ID collating unit 11 may collate the mobile terminal identifier and collate the user ID.

  FIG. 3 is a configuration diagram of the main control unit 10 of the multifunction machine 1. The main control unit 10 has a processor 101, a RAM 102, a ROM 103, and a bus connecting them. A storage device 104 and various devices 105 are connected to the bus.

  The processor 101 operates a program and performs various controls related to various devices 105. The RAM 102 temporarily stores information as a work area. Programs and various setting information are stored in the ROM 103 and the storage device 104.

~ Control flow ~
FIG. 4 is a control flow diagram showing advance preparation according to the first embodiment. First, the control flow when using the mobile terminal 20 (control unique to this embodiment) will be described.

  The communication control unit 18 of the multifunction device 1 is always looking for radio waves (short-range wireless communication) from the mobile terminal 20. While communication with the mobile terminal 20 is established, the identifier of the mobile terminal 20 that has become communicable is identified (step S10).

  When the mobile terminal first approach detection unit 32 detects that the mobile terminal 20 is in the first approach state (details will be described later, refer to the description corresponding to FIG. 5) (step S20), the mobile terminal collation unit 33 sets the mobile terminal. 20 is collated to determine whether or not it is registered in advance (step S30). If the mobile terminal verification unit 33 determines that the verification does not match, the process returns to step S10.

  In step S30, when the mobile terminal verification unit 33 determines that the verification matches, the mobile terminal second approach detection unit 35 determines whether or not a second approach state has been detected (details will be described later, see the description corresponding to FIG. 5). (Step S40).

  If it is determined in step 40 that the mobile terminal second approach detection unit 35 has not detected the second approach state, it is determined whether or not a predetermined time has passed in the state in which the second approach state has not been detected (step). S70). If the predetermined time has not elapsed, the process returns to step S40. That is, step 40 and step 70 are repeated for a predetermined time. If the predetermined time has elapsed, the process returns to step S10.

  If it is determined in step 40 that the mobile terminal second approach detection unit 35 has detected the second approach state, the use permission unit 12 regards that the user of the mobile terminal 20 is permitted to use the multifunction device 1. The user is granted permission to use (step S50).

  Thereafter, the power supply control unit 13 cancels the sleep state, and the multifunction device 1 enters the usable state when the warm-up is completed (step S60).

  For comparison, a control flow when the mobile terminal 20 is not used (control as in the conventional case) will be described.

  The power control unit 13 of the multifunction machine 1 stands by in the sleep state. When the user presses a switch, the power supply control unit 13 detects a switch input signal. (Step S80).

  The power control unit 13 cancels the sleep state and activates the operation / display panel 3. The panel control unit 14 displays an input screen related to the user ID and password. When the ID collation unit 11 collates the user ID and password, the use permission unit 12 grants the use permission to the user as if the use of the multifunction device 1 was permitted (step S90).

  Thereafter, upon completion of warm-up, the multifunction device 1 becomes ready for use (step S60).

~ Operation example ~
Hereinafter, the operation of the user and the operation of the multifunction machine will be described.

  Operation Example 1 (Operation Same as Conventional): An operation when the user does not carry the mobile terminal 20 will be described. The multi-function device 1 cannot detect radio waves from the mobile terminal 20.

  When the user stands in front of the multifunction machine 1 and presses the power switch, the sleep mode is canceled and a screen for user verification is displayed on the operation / display panel 3. When the user inputs an appropriate user ID and password, the multifunction device 1 becomes ready for use for a while (S80 → S90 → S60).

  On the operation / display panel 3, a screen related to the operation is displayed. The user performs an operation relating to copying or the like via the operation / display panel 3.

  Operation Example 2 (First Embodiment Basic Operation): An operation when the user uses the multifunction device 1 by utilizing the mobile terminal 20 will be described. The multi-function device 1 constantly searches for radio waves from the mobile terminal 20.

  In order to use the multifunction device 1, the user carries the mobile terminal 20 and approaches the multifunction device 1. When entering the first approach state, the multifunction device 1 starts preparation (for example, collation). When the mobile terminal 20 is registered in advance, when the user further approaches and stops moving in front of the multifunction machine 1 (second approach state), the use permission is automatically given. Further, the sleep mode is canceled without pressing the power switch. The multifunction device 1 is ready for use (S10 → S20 → S30 → S40 → S70 → S40 → S50 → S60).

  On the operation / display panel 3, a screen related to the operation is displayed. The user performs an operation relating to copying or the like via the operation / display panel 3.

  Operation Example 3: An operation when the user carrying the mobile terminal 20 moves near the multifunction device 1 but does not use the multifunction device 1 (passes through) will be described. The multi-function device 1 constantly searches for radio waves from the mobile terminal 20.

  When the user carries the mobile terminal 20 and approaches the multifunction device 1 and enters the first approach state, the multifunction device 1 starts pre-preparation (for example, collation). However, use permission is not automatically granted unless the second approach state is entered. The multifunction device 1 waits for detection of the second approach state for a predetermined time, but when the predetermined time has elapsed, the multifunction device 1 stops the control related to the mobile terminal 20 (S10 → S20 → S30 → S40 → S70 → S40 → S70 → S10).

  At this time, the sleep is not canceled and the operation / display panel 3 is not activated.

  Operation Example 4: The operation when a user who carries a mobile terminal 20 that is not registered in advance uses the multifunction device 1 (matching mismatch) will be described. The multi-function device 1 constantly searches for radio waves from the mobile terminal 20.

  When the user carries the mobile terminal 20 and approaches the multifunction device 1 and enters the first approach state, the multifunction device 1 starts pre-preparation (for example, collation). However, the use permission is not automatically granted even if the second approach state is caused due to the mismatch of collation (S10 → S20 → S30 → S10). At this time, the sleep is not canceled and the operation / display panel 3 is not activated.

  The user stands in front of the multifunction machine 1 and performs the same operation as in the operation example 1 (S80 → S90 → S60).

~ Approach detection ~
FIG. 5 is an explanatory diagram relating to approach detection according to the first embodiment. A user of the multifunction device 1 approaches the multifunction device 1 in order to use the multifunction device 1. The first approach state and the second approach state at this time will be described.

  The first approach state is a state with a high probability that the user is approaching the multifunction device 1. The second approach state is a state in which the user of the multifunction device 1 is stopped moving in front of the multifunction device 1. Note that the movement stop does not mean a complete immovable state, but means that the MFP 1 is within the operable range.

  The mobile terminal first approach detection unit 32 detects the first approach state based on the received electric field strength, and the mobile terminal second approach detector 35 detects the second approach state based on the received electric field strength.

  FIG. 6A is a diagram illustrating an example of the first approach state detection. When the user carries the mobile terminal 20 and approaches the multi-function device 1, there is a slight increase or decrease, but if the received electric field strength history is smoothed, it tends to increase monotonously. When the approximate expression of the received electric field strength history exceeds a predetermined threshold, or / and when the inclination of the approximate expression falls within a predetermined range, the mobile terminal first approach detection unit 32 has detected the first approach state. to decide.

  By the way, the mobile terminal 20 has an acceleration sensor 24. The mobile terminal first approach detection unit 32 may acquire the acceleration history of the mobile terminal 20 via short-range wireless communication, and may detect the first approach state together with the determination based on the received electric field strength.

  For example, when the acceleration exceeds a predetermined threshold or / and when an acceleration history pattern resulting from walking is recognized, it is determined that the first approach state has been detected.

  FIG. 6B is a diagram illustrating an example of second approach state detection. When the user of the multi-function device 1 stops moving in front of the multi-function device 1, the received electric field strength history that has been monotonously increasing hardly increases (substantially zero when the approximate expression is differentiated). If this state continues, the mobile terminal second approach detection unit 35 determines that the second approach state has been detected.

  However, if the zero state does not continue after differentiation, it is determined that the user has passed (dotted line in the figure).

  The mobile terminal second approach detection unit 35 may acquire the acceleration history of the mobile terminal 20 via short-range wireless communication, and may detect the second approach state together with the determination based on the received electric field strength. For example, when the user of the multifunction device 1 stops moving in front of the multifunction device 1, the acceleration becomes almost zero. Thereby, it is judged that the mobile terminal 2nd approach detection part 35 detected the 2nd approach state.

  If the two antennas 8 are provided at the left and right ends of the multi-function device 1, the influence of blind spots and the like can be reduced, and the approaching state can be detected more reliably based on the received electric field strength.

~effect~
The effects according to the first embodiment will be described by comparing the above operation examples.

  Comparing operation example 1 (same operation as before) and operation example 2 (basic operation of the present embodiment), the user uses the mobile terminal 20 to manually release the sleep or manually authenticate the user (verification and use permission). Is no longer necessary. As a result, the waiting time until the multifunction device 1 becomes usable can be shortened.

  When the operation example 2 and the operation example 3 (passing operation) are compared, if the user does not intend to use the multifunction device 1, the use permission is not given. Also, it does not wake up from sleep. That is, by preventing malfunction, the information management property and energy saving property of the multifunction device 1 are maintained.

  When the operation example 2 and the operation example 4 (collation mismatch) are compared, the use permission is not automatically given to the mobile terminal 20 not registered in advance. Thereby, the information manageability of the multifunction device 1 is maintained.

  As described above, it is possible to improve convenience while maintaining information management and energy saving.

-Summary after using the MFP-
In the foregoing, the description has been given of the process until the user of the multifunction device 1 approaches the multifunction device 1 and uses the multifunction device 1. Hereinafter, a description will be given of when the multifunction device is used and after the multifunction device.

  FIG. 7 is a control flow diagram after using the multifunction machine. First, the control flow when using the mobile terminal 20 (control unique to this embodiment) will be described.

  When the mobile terminal second approach detection unit 35 determines that the second approach state has been detected, the use permission unit 12 considers that the user of the mobile terminal 20 is permitted to use the multifunction device 1 and permits the use. (Step S50).

  While the mobile terminal second approach detection unit 35 continues the second approach state detection, the use permission unit 12 continues to grant use permission. If it is determined that the mobile terminal second approach detection unit 35 has not detected the second approach state, it is determined whether or not the second approach state has not been detected until a predetermined time has elapsed (step S100). If the predetermined time has not elapsed, the determination in step 100 is repeated.

  In step S100, when a state in which the second approach state is not detected has elapsed for a predetermined time, the use permission unit 12 disallows use (S110). The power supply control unit 13 enters a sleep state (S120).

  For comparison, a control flow when the mobile terminal 20 is not used (control as in the conventional case) will be described.

  When the ID collation unit 11 collates the user ID and password, the use permission unit 12 grants use permission to the user (step S90).

  When the panel control unit 14 detects the operation signal, the use permission unit 12 continues to grant the use permission for a predetermined time. Further, it is determined whether or not a predetermined time has elapsed since the next operation signal was not detected since the previous operation signal was detected (step S130). If the predetermined time has not elapsed, the determination in step 130 is repeated.

  In step S130, when the next operation signal is not detected after the previous operation signal is detected and the predetermined time has elapsed, the use permission unit 12 prohibits the use (S110). The power supply control unit 13 enters a sleep state (S120).

  Further, the operation of the user and the operation of the multifunction machine will be described.

  Operation Example 5 (Same as Conventional Operation): The operation when the user does not carry the mobile terminal 20 will be described. The multi-function device 1 cannot detect radio waves from the mobile terminal 20.

  When the desired work (for example, copying) is completed, the user leaves the front of the multifunction device 1. Of course, the following operations are not performed. After a predetermined time has elapsed since the previous operation, the multifunction device 1 is automatically disabled and enters a sleep mode (S90 → S130 → S110 → S120).

  Operation Example 6 (Basic Operation of the Present Embodiment): An operation when the user uses the mobile terminal 20 will be described. The multi-function device 1 constantly searches for radio waves from the mobile terminal 20.

  When the desired work (for example, copying) is completed, the user leaves the front of the multifunction device 1. The second approach state is not detected. After a predetermined time has elapsed, the multifunction device 1 is automatically disabled and enters a sleep mode (S50 → S100 → S110 → S120).

  By comparing the operation example 5 (similar to the conventional operation) and the operation example 6 (the basic operation of the present embodiment), additional effects according to the first embodiment will be additionally described below.

  The operation example 5 and the operation example 6 are common in that the multifunction device 1 is automatically disabled when a predetermined time (standby time) elapses. However, in the operation example 6, compared with the operation example 5, the predetermined time until it becomes unusable can be set short. Thereby, the information manageability of the multifunction device 1 is maintained. This point will be supplemented below.

  By the way, the user sometimes takes time in front of the multifunction machine 1. For example, the page to be copied may be examined, or the contents to be transmitted by facsimile may be confirmed again. Even in such a case, in the operation example 5, the operation signal cannot be detected, and the multifunction device 1 is automatically disabled after a predetermined time, and enters the sleep mode. The user needs to repeat the operation example 1 again.

  If the predetermined time in step 130 is set longer, the usable state is continued even if the user takes time in front of the multifunction device 1. However, in the operation example 5, if the predetermined time is set to be long, the usable state is continued for a while after the multifunction device is used. This is not preferable because an unintended third party may use the multifunction device 1.

  That is, in the operation example 5, convenience and information management are in a trade-off relationship.

  On the other hand, in the operation example 6, when the user uses the mobile terminal 20, even if the user takes time in front of the multifunction machine 1, the second approach state is detected and the usable state is continued. Thereby, the convenience of the multifunction device 1 can be improved.

  In the operation example 6, the problem related to the predetermined time setting in the operation example 5 does not occur, and the predetermined time in step 100 can be set relatively short. There is little possibility that an unintended third party uses the multifunction device 1. Thereby, the information manageability of the multifunction device 1 is maintained (if the convenience is equivalent to that of the operation example 5, the information manageability is improved).

  That is, in the operation example 6, it is possible to improve convenience while maintaining information management and energy saving.

Second Embodiment
~Overview~
In the first embodiment, when the first approach state is detected, the mobile terminal is collated based on the identifier of the mobile terminal, and when the second approach state is detected, the use permission state is set. After making the use permitted state, further preparations such as sleep release are made.

  In the second embodiment, the specific preliminary preparation is started after the first approach state is detected and before the second approach state is detected by effectively utilizing the time from the first approach state detection to the second approach state detection. The specific advance preparation is preparation different from verification and use permission. Specific examples will be mentioned in the description of the control flow below.

  The second embodiment is a modification of the first embodiment, and the schematic configuration and the like refer to FIGS.

~ Control flow ~
FIG. 8 is a control flow diagram showing advance preparation according to the second embodiment. A control flow when using the mobile terminal 20 (control unique to this embodiment) will be described.

  The communication control unit 18 of the multifunction device 1 is always looking for radio waves (short-range wireless communication) from the mobile terminal 20. While communication with the mobile terminal 20 is established, the identifier of the mobile terminal 20 that has become communicable is identified (step S10).

  When the mobile terminal first approach detection unit 32 detects that the mobile terminal 20 is in the first approach state (step S20), the mobile terminal collation unit 33 collates the mobile terminal 20 and whether it is registered in advance. Is determined (step S30). If the mobile terminal verification unit 33 determines that the verification does not match, the process returns to step S10.

  In step S30, when the mobile terminal verification unit 33 determines that the verification matches, each unit of the main control unit 10 performs control related to the specific advance preparation start (step S32). For example, the power control unit 13 cancels the sleep state. The image reading control unit 15 prepares for scanning driving. The scanning image formation control unit 16 warms up the fixing device.

  Note that the specific pre-preparation preferably does not include preparations for enabling / displaying the operation / display panel 3.

  Thereafter, the mobile terminal second approach detection unit 35 determines whether or not the second approach state has been detected (step S40).

  If it is determined in step 40 that the mobile terminal second approach detection unit 35 has not detected the second approach state, it is determined whether or not a predetermined time has passed in the state in which the second approach state has not been detected (step). S70). If the predetermined time has not elapsed, the process returns to step S40. That is, step 40 and step 70 are repeated for a predetermined time.

  In step S70, when a predetermined time has elapsed, control related to the specific advance preparation stop is performed, and the process returns to step S10. (Step S72).

  If it is determined in step 40 that the mobile terminal second approach detection unit 35 has detected the second approach state, the use permission unit 12 regards that the user of the mobile terminal 20 is permitted to use the multifunction device 1. The user is granted permission to use (step S50).

  The panel control unit 14 makes the operation / display panel 3 operable / displayable, and upon completion of the specific advance preparation in step S32, the multifunction device 1 is ready for use (step S60).

  The control flow when the mobile terminal 20 is not used (the same control as in the prior art) is the same as in the first embodiment.

~ Operation example ~
Hereinafter, the operation of the user and the operation of the multifunction machine will be described.

  Operation Example 7 (Basic Operation of Second Embodiment): An operation when the user uses the multifunction device 1 by using the mobile terminal 20 will be described. The multi-function device 1 constantly searches for radio waves from the mobile terminal 20.

  In order to use the multifunction device 1, the user carries the mobile terminal 20 and approaches the multifunction device 1. When entering the first approach state, the multifunction device 1 starts collation and specific preparation. When the user approaches further and stops moving in front of the multifunction machine 1 (second approach state), the use permission is automatically given, and the operation / display panel 3 is operable / displayable. . As soon as the specific pre-preparation is completed, the multifunction device 1 becomes ready for use (S10 → S20 → S30 → S32 → S40 → S70 → S40 → S50 → S60).

  On the operation / display panel 3, a screen related to the operation is displayed. The user performs an operation relating to copying or the like via the operation / display panel 3.

  Operation Example 8: An operation when the user carrying the mobile terminal 20 moves near the multifunction device 1 but does not use the multifunction device 1 (passes through) will be described. The multi-function device 1 constantly searches for radio waves from the mobile terminal 20.

  When the user carries the mobile terminal 20 and approaches the multifunction device 1 and enters the first approach state, the multifunction device 1 starts collation and specific preparation. However, unless the second approach state is entered, the use permission is not automatically granted, and the operation / display panel 3 is not operable / displayable. The multifunction device 1 waits for the second approach state detection for a predetermined time, but when the predetermined time elapses, the specific advance preparation is stopped and the control related to the mobile terminal 20 is stopped (S10 → S20 → S30 → S32 → S40 → S70). → S40 → S70 → S72 → S10).

  At this time, the sleep is not canceled and the operation / display panel 3 is not activated.

  If the specific preliminary preparation includes preparation for enabling / displaying the operation / display panel 3, in the operation example 8 (passing), the operation / display panel 3 becomes operable / displayable. Irrespective of this, there is a risk of causing unnecessary confusion for a third party around the multifunction peripheral.

~effect~
The effects according to the second embodiment will be described by comparing the above operation examples.

  Comparing operation example 2 (first embodiment) and operation example 7 (second embodiment), the result of starting the specific advance preparation by effectively using the time from the first approach state detection to the second approach state detection The waiting time until the multifunction device 1 becomes usable can be further shortened.

  When the operation example 7 (basic operation) and the operation example 8 (passing) are compared, if the user does not intend to use the multifunction device 1, the use permission is not given and the specific advance preparation is stopped. Further, the operation / display panel 3 cannot be operated / displayed. That is, by preventing malfunction, the information management property and energy saving property of the multifunction device 1 are maintained.

  As described above, it is possible to further improve convenience while maintaining information management and energy saving.

<Third Embodiment>
~Overview~
In 2nd Embodiment, if a 1st approach state is detected, it will collate and a specific advance preparation will be started. On the other hand, in 3rd Embodiment, after collation, specific prior preparation is started based on mobile terminal state information (details mention later, refer description corresponding to FIG. 11).

~ Configuration / Control ~
The third embodiment is a modification of the second embodiment (first embodiment), and the schematic configuration is illustrated with reference to FIG.

  FIG. 9 is a schematic configuration diagram of the mobile terminal 20 according to the third embodiment and a functional block diagram of the main control unit 10 of the multifunction machine 1.

  First, a schematic configuration of the mobile terminal 20 will be described. It is almost the same as the first embodiment. The mobile terminal 20 is equipped with various sensors such as an acceleration sensor 24 and a brightness sensor 25. Many programs (applications) 26 stored in the mobile terminal 20 operate based on information acquired from various sensors. Information of various sensors can be transmitted to the multifunction device 1 via the communication unit 21. An operation application 27 of the multifunction device 1 is stored as one of various applications.

  Next, a functional block diagram of the main control unit 10 of the multifunction machine 1 in the third embodiment will be described. The mobile terminal state information detection unit 34 is added to the functional block diagram (see FIG. 2) of the first embodiment. Characteristic relationships between the main control units are indicated by arrows.

  The mobile terminal state information detection unit 34 communicates with the mobile terminal 20 and detects the state information of the mobile terminal 20. If the mobile terminal status information detection unit 34 determines that the status information of the mobile terminal 20 has been detected, each unit of the main control unit 10 (for example, the power supply control unit 13) performs control related to the start of specific preparatory preparation (see the arrow in the figure). .

  FIG. 10 is a control flow diagram illustrating advance preparation according to the third embodiment. Differences from the control flow diagram showing advance preparation according to the second embodiment shown in FIG. 8 will be described.

  The control up to step S30 is the same as in the second embodiment.

  In step S30, when the mobile terminal verification unit 33 determines that the verification matches, the mobile terminal status information detection unit 34 determines whether status information of the mobile terminal 20 has been detected (step S31).

  If it is determined in step S31 that the mobile terminal state information detection unit 34 has detected the state information of the mobile terminal 20, each unit of the main control unit 10 performs control related to the start of specific preparatory preparation (step S32). For example, the power control unit 13 cancels the sleep state. The image reading control unit 15 prepares for scanning driving. The scanning image formation control unit 16 warms up the fixing device. Thereafter, the mobile terminal second approach detection unit 35 determines whether or not the second approach state has been detected (step S40).

  If it is determined in step S31 that the mobile terminal status information detection unit 34 has not detected the status information of the mobile terminal 20, the mobile terminal second approach detection unit 35 performs the first control without performing control related to the specific advance preparation start. It is determined whether or not a two approaching state is detected (step S40).

  The control after step S40 is the same as in the second embodiment. The control flow when the mobile terminal 20 is not used (the same control as in the prior art) is the same as in the first embodiment.

~ Operation example ~
Hereinafter, the operation of the user and the operation of the multifunction machine will be described.

  Operation Example 9 (Using Operation Application): An operation when the user uses the multifunction device 1 using the operation application 27 will be described. The multi-function device 1 constantly searches for radio waves from the mobile terminal 20.

  In order to use the multifunction device 1, the user carries the mobile terminal 20 and approaches the multifunction device 1. At that time, the user is going to use the operation application 27. Thereby, the status information of the mobile terminal is detected. When entering the first approach state, the multifunction device 1 starts collation and specific preparation. When the user further approaches and stops moving in front of the multifunction machine 1 (second approach state), the use permission is automatically given. As soon as the specific advance preparation is completed, the multi-function device 1 becomes ready for use (S10 → S20 → S30 → S31 → S32 → S40 → S70 → S40 → S50 → S60).

  The user performs an operation related to copying or the like via the operation application 27. At this time, the user can operate the operation application 27 without making the operation / display panel 3 operable / displayable.

  Operation Example 10 (No Operation App Use): The operation when the user carrying the mobile terminal 20 uses the multifunction device 1 without using the operation application 27 will be described. The multi-function device 1 constantly searches for radio waves from the mobile terminal 20.

  In order to use the multifunction device 1, the user carries the mobile terminal 20 and approaches the multifunction device 1. At this time, if the mobile terminal 20 is in a pocket or a bag, for example, the status information of the mobile terminal is not detected. When entering the first approach state, the multifunction device 1 starts collation. When the user further approaches and stops moving in front of the multifunction machine 1 (second approach state), the use permission is automatically given. Further, the sleep mode is canceled without pressing the power switch, and the multifunction device 1 becomes usable (S10 → S20 → S30 → S31 → S40 → S70 → S40 → S50 → S60) (see operation example 2).

  On the operation / display panel 3, a screen related to the operation is displayed. The user performs an operation relating to copying or the like via the operation / display panel 3.

~effect~
The effects according to the third embodiment will be described by comparing the above operation examples.

  The operation examples 7 and 8 (second embodiment) and the operation example 9 (third embodiment) are compared. In the second embodiment, it is premised on normal operation (Operation Example 7), but there is also a possibility of a temporary malfunction (Operation Example 8). In the third embodiment, as in the operation example 9, the specific advance preparation is started based on the state information of the mobile terminal. Since there is a high probability that the user will use the multifunction device 1, the possibility of malfunctioning is extremely low. Thereby, energy saving property is maintained.

  When it becomes mainstream to use the multifunction device 1 using the operation application 27 as in the operation example 9, the usefulness of the operation / display panel 3 is relatively lowered. As a result, the configuration of the operation / display panel 3 can be simplified.

~ Mobile terminal status information ~
FIG. 11 is an example of mobile terminal state information. The mobile terminal state information is information that can be preliminarily determined according to the state of the mobile terminal 20 so that the user can predict that the multifunction device 1 is likely to be used.

  In FIG. 11A, brightness information and angle information are shown as examples of the mobile terminal state information.

  If the state where the angle (attitude) of the mobile terminal 20 is within the predetermined range continues, it can be estimated that the mobile terminal 20 is operated by the user.

  It is highly probable that the user will use the multifunction device 1 by using the operation application 27 when approaching the multifunction device 1 while operating the mobile terminal 20. The angle information is measured by the acceleration sensor 24 of the mobile terminal 20 and transmitted to the multifunction device 1. The multifunction device 1 detects mobile terminal state information.

  When the brightness is less than the predetermined value, it is estimated that the mobile terminal 20 is in a pocket or a bag. When the brightness is equal to or higher than a predetermined value, it can be estimated that the mobile terminal 20 is outside the pocket or bag. In particular, if the state where the lightness is equal to or higher than a predetermined value continues, it can be estimated that the mobile terminal 20 is operated by the user.

  It is highly probable that the user will use the multifunction device 1 by using the operation application 27 when approaching the multifunction device 1 while operating the mobile terminal 20. The lightness information is measured by the lightness sensor 25 of the mobile terminal 20 and transmitted to the multifunction device 1. The multifunction device 1 detects mobile terminal state information.

  FIG. 11B shows special operation pattern information as an example of the mobile terminal state information.

  An acceleration history pattern that is clearly different from the acceleration history pattern resulting from walking is set as an indication of the intention to use the multifunction device. For example, an action of shaking the mobile terminal 20 to the left and right several times is used as a multifunction device use intention display.

  It is highly probable that the user uses the operation application 27 to display the intention through the mobile terminal 20 and approach the multifunction device 1. The acceleration history pattern is measured by the acceleration sensor 24 of the mobile terminal 20 and transmitted to the multi function device 1. The multifunction device 1 detects mobile terminal state information.

  FIG. 11C shows activation information of the operation application 27 as an example of the mobile terminal state information.

  If the user activates the operation application 27 and approaches the multifunction device 1, the user is likely to use the multifunction device 1 using the operation application 27. The operation application 27 is selected on the touch panel (display 22) and executed by the control unit 23. The activation information of the operation application 27 is transmitted to the multifunction device 1. The multifunction device 1 detects mobile terminal state information.

~ Detailed specific preparations ~
FIG. 11C shows an example of an operation screen by the operation application 27. On the touch panel (display 22), an operation screen for selecting one of the functions of the multifunction peripheral relating to printing, copying, scanning, and facsimile is displayed.

  When the mobile terminal state information is function selection information, more detailed specific preparation is possible.

  When printing is selected, power saving cancellation, warm-up operation, print file list acquisition, print file download, and the like of the image forming apparatus 5 are performed in advance.

  When copying is selected, power saving cancellation, warm-up operation, pre-scanning, and the like of the image reading device 4 and the image forming device 5 are performed in advance.

  When scanning or facsimile is selected, power saving cancellation, pre-scanning, and the like of the image reading device 4 are performed in advance.

  Thereby, energy saving property is more reliably maintained.

  In the above embodiment, the approach of the user is determined based on the received electric field strength related to the radio wave from the mobile terminal and supplemented by the acceleration information of the mobile terminal, but other means may be used as long as the approach can be detected.

  In the above-described embodiment, attention is paid to the received electric field strength related to the radio wave related to the short-range wireless communication. However, the received electric field strength of the radio wave related to the wireless LAN may be acquired via the router.
