Description

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

In recent years, mobile terminals such as smartphones and tablets have become widespread. Because of its relatively low price and small size and portability, it is often carried by each person at all times. It is also 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 device has been proposed by utilizing such features of a mobile terminal. For example, the multifunction device described in Patent Document 1 detects that a mobile terminal is mounted on the multifunction device, acquires posture information of the mobile terminal via a communication function, and determines an operation mode based on the posture information. ..

Specifically, if the display of the mobile terminal has attitude information facing the mounting surface of the multifunction device, the print mode is determined, and the 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.

By the way, in recent years, information management has become stricter. Information manageability is also required for multifunction devices. For example, by entering the user ID and password, the user is authenticated and the multifunction device can be used.

Attention is also being paid to energy saving. Energy saving is also required for multifunction devices. For example, if the device is not used for a predetermined period of time, the multifunction device shifts to the sleep mode for reducing power consumption.

In this way, in a multifunction device provided with user authentication and sleep mode, the user presses a switch to switch from sleep mode to wake-up mode, enables the display panel to be displayed, and inputs a user ID and password.

It has a fixing portion for fixing the image on the recording paper after transfer on the top. Based on the command of the main control device 10, the image data acquired from the outside via the communication device 7 or the image data acquired by the image reading device 4 is formed as an image on the recording paper.

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

The communication device 7 is connected to a network line, and inputs and outputs information to and from 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 (solid line in the figure) and controls each device.

In the present embodiment, the multifunction device 1 can communicate with a mobile terminal 20 such as a smartphone or a tablet. Data communication is performed via a network line via a router, and direct communication is performed by short-range wireless communication (NFC (Near Field Communication)). That is, the communication device 7 also performs short-range wireless communication. BLUETOOTH® is an example of short-range wireless communication.

The multifunction device 1 includes an antenna 8. The multifunction device 1 measures the strength (electric field strength) of the radio wave (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 device 1.

First, the schematic configuration of the mobile terminal 20 will be described. For example, the mobile terminal 20 is a smartphone or 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 via a network line via a router, and direct communication is performed by 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 of the programs (apps) 26 stored in the mobile terminal 20 operate based on the information acquired from various sensors. The various sensors will be described in detail in the third embodiment.

That is, the user is regarded as having been authenticated and the subsequent operation is performed.

The power supply control unit 13 controls the power supply device 2. In particular, if it is determined that the start mode is changed to the sleep mode under a predetermined condition, the power supply to each device is reduced. The power supply can be controlled individually for each device. For example, in the case of printing, the sleep state of the image forming apparatus 5 can be released while maintaining the sleep state of the image reading device 4.

It should be noted that the print request and the facsimile reception request can always be received, thereby releasing the sleep state related to the corresponding device.

Further, electric power is constantly supplied to the communication device 7 (particularly, the communication unit related to short-range wireless communication). Short-range wireless communication consumes less power and meets the demand for energy saving even when it is always running.

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

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

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

The mobile terminal collation unit 33 acquires the identifier of the mobile terminal 20 through communication with the mobile terminal 20, and collates 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 is closer to the multifunction device 1 than the first approach state and has stopped moving within the operable range of the multifunction device 1 (second approach state) (details will be described later). Refer to the description corresponding to FIG. 5).

After the second approach state is detected, the use permission unit 12 considers that the user is permitted to use the multifunction device 1 based on the collation match in the mobile terminal collation unit 33, and grants the use permission. Grant (see the arrow in the figure). Further, the storage unit 19 stores an identifier unique to the mobile terminal corresponding to the mobile terminal 20 to which the access right is granted.

Further, the storage unit 19 may store the user ID and password in association with the mobile terminal identifier, and the ID collation 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 device 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. The program 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, a control flow in the case of utilizing the mobile terminal 20 (control peculiar to the present embodiment) will be described.

The communication control unit 18 of the multifunction device 1 is constantly searching for radio waves (short-range wireless communication) from the mobile terminal 20. Communication with the mobile terminal 20 is established, and the identifier of the mobile terminal 20 that has become able to communicate 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, see the description corresponding to FIG. 5) (step S20), the mobile terminal collation unit 33 causes the mobile terminal. 20 is collated and it is determined whether or not it is registered in advance (step S30). If the mobile terminal collation unit 33 determines that the collation does not match, the process returns to step S10.

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

In step 40, 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 state in which the second approach state has not been detected has elapsed for a predetermined time (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. When the predetermined time has elapsed, the process returns to step S10.

When 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 considers that the user of the mobile terminal 20 is permitted to use the multifunction device 1. In the meantime, a license is granted (step S50).

After that, the power supply control unit 13 releases the sleep state, and when the warm-up is completed, the multifunction device 1 becomes usable (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 supply control unit 13 of the multifunction device 1 stands by in a sleep state. When the user presses the switch, the power supply control unit 13 detects the switch input signal. (Step S80).

The power control unit 13 releases 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 license unit 12 grants the user permission to use the multifunction device 1 on the assumption that the user is permitted to use the multifunction device 1 (step S90).

After that, when the warm-up is completed, the multifunction device 1 becomes usable (step S60).

~ Operation example ~
The operation of the user and the operation of the multifunction device will be described below.

Operation example 1 (operation as in the conventional case): An operation when the user does not carry the mobile terminal 20 will be described. The multifunction device 1 cannot detect the radio wave from the mobile terminal 20.

When the user stands in front of the multifunction device 1 and presses the power switch, the sleep mode is released and the operation / display panel 3 displays a screen related to user verification. When the user inputs an appropriate user ID and password, the multifunction device 1 becomes usable after a while (S80 → S90 → S60).

A screen related to the operation is displayed on the operation / display panel 3. The user performs an operation related to copying or the like via the operation / display panel 3.

Operation example 2 (basic operation of the first embodiment): An operation when the user uses the multifunction device 1 by utilizing the mobile terminal 20 will be described. The multifunction device 1 is constantly searching 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 the first approaching state is reached, the multifunction device 1 starts advance preparation (for example, collation). When the mobile terminal 20 is registered in advance, a license is automatically granted when the user approaches further and stops moving in front of the multifunction device 1 (second approach state). In addition, sleep mode is released without pressing the power switch. The multifunction device 1 is ready for use (S10 → S20 → S30 → S40 → S70 → S40 → S50 → S60).

A screen related to the operation is displayed on the operation / display panel 3. The user performs an operation related to copying or the like via the operation / display panel 3.

Operation example 3: The operation when the user carrying the mobile terminal 20 moves near the multifunction device 1 but does not use the multifunction device 1 (passing by) will be described. The multifunction device 1 is constantly searching for radio waves from the mobile terminal 20.

When the user carries the mobile terminal 20 and approaches the multifunction device 1, and the first approach state is reached, the multifunction device 1 starts advance preparation (for example, collation). However, the license is not automatically granted unless the second approach state is reached. The multifunction device 1 waits for the second approach state detection for a predetermined time, but when the predetermined time elapses, the control of the mobile terminal 20 is stopped (S10 → S20 → S30 → S40 → S70 → S40 → S70 → S10).

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

Operation example 4: An operation when a user carrying a mobile terminal 20 which is not registered in advance uses the multifunction device 1 (matching mismatch) will be described. The multifunction device 1 is constantly searching for radio waves from the mobile terminal 20.

When the user carries the mobile terminal 20 and approaches the multifunction device 1, and the first approach state is reached, the multifunction device 1 starts advance preparation (for example, collation). However, due to the collation mismatch, the license is not automatically granted even in the second approach state (S10 → S20 → S30 → S10). At this time, the sleep is not released and the operation / display panel 3 is not activated.

The user stands in front of the multifunction device 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. The user of the multifunction device 1 approaches the multifunction device 1 in order to use the multifunction device 1. The first approaching state and the second approaching state at this time will be described.

The first approaching state is a state in which it is highly probable that the user is approaching the multifunction device 1. The second approaching 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 completely immobile state, but means that the multifunction device 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 detection unit 35 detects the second approach state based on the received electric field strength.

FIG. 6A is a diagram showing an example of the first approach state detection. When the user carries the mobile terminal 20 and approaches the multifunction device 1, the reception electric field strength history tends to increase monotonically, although there is some increase or decrease. When the approximate expression of the received electric field strength history exceeds a predetermined threshold value, or / and when the inclination of the approximate expression is within the predetermined range, the mobile terminal first approach detection unit 32 detects 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 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 value and / or when the acceleration history pattern caused by walking is recognized, it is determined that the first approach state has been detected.

FIG. 6B is a diagram showing an example of the second approach state detection. When the user of the multifunction device 1 stops moving in front of the multifunction device 1, the received electric field strength history, which has tended to increase monotonically, hardly increases (almost zero when the approximate expression is differentiated). When 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 judged that the user has passed (dotted line in the figure).

Further, the mobile terminal second approach detection unit 35 may acquire the acceleration history of the mobile terminal 20 via short-range wireless communication and 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. As a result, the mobile terminal second approach detection unit 35 determines that the second approach state has been detected.

If the two antennas 8 are provided on the left and right ends of the multifunction 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~
By comparing the above operation examples, the effect according to the first embodiment will be described.

Comparing operation example 1 (operation as in the conventional operation) and operation example 2 (basic operation of the present embodiment), the user can manually wake up from sleep and manually authenticate the user (verification and permission to use) by utilizing the mobile terminal 20. Is no longer needed. As a result, the waiting time until the multifunction device 1 can be used can be shortened.

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

Comparing the operation example 2 and the operation example 4 (matching mismatch), the usage permission is not automatically given to the mobile terminal 20 which is not registered in advance. As a result, the information manageability of the multifunction device 1 is maintained.

As described above, convenience can be improved while maintaining information management and energy saving.

~ Overview after using the multifunction device ~
The process of the user of the multifunction device 1 approaching the multifunction device 1 and using the multifunction device 1 has been described above. Hereinafter, the use and after use of the multifunction device will be described.

FIG. 7 is a control flow diagram after using the multifunction device. First, a control flow in the case of utilizing the mobile terminal 20 (control peculiar to the present 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 has been 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 the 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 elapses (step S100). If the predetermined time has not elapsed, the determination in step 100 is repeated.

In step S100, when the state in which the second approach state is not detected elapses for a predetermined time, the use permission unit 12 disallows the use (S110). The power control unit 13 is put into 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 the 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 the next operation signal has not been detected since the previous operation signal detection and a predetermined time has elapsed (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 and a predetermined time elapses after the previous operation signal is detected, the use permission unit 12 disallows the use (S110). The power control unit 13 is put into a sleep state (S120).

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

Operation example 5 (similar to the conventional operation): An operation when the user does not carry the mobile terminal 20 will be described. The multifunction device 1 cannot detect the radio wave from the mobile terminal 20.

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

Operation example 6 (basic operation of the present embodiment): An operation when the user utilizes the mobile terminal 20 will be described. The multifunction device 1 is constantly searching 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 no longer detected. After the lapse of a predetermined time, the multifunction device 1 is automatically disabled and enters the sleep mode (S50 → S100 → S110 → S120).

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

Both the operation example 5 and the operation example 6 are common in that the multifunction device 1 is automatically disabled after a predetermined time (standby time) elapses. However, in the operation example 6, the predetermined time until the operation becomes unusable can be set shorter than that in the operation example 5. As a result, the information manageability of the multifunction device 1 is maintained. This point will be supplemented below.

By the way, the user may take time in front of the multifunction device 1. For example, you may consider which page to copy, or reconfirm what you are faxing. Even in such a case, in the operation example 5, the operation signal cannot be detected, and after a lapse of a predetermined time, the multifunction device 1 is automatically disabled and the sleep mode is set. The user needs to repeat the operation example 1 again.

If the predetermined time in step 130 is set to be long, 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 even after the multifunction device is used. It is not preferable because there is a possibility that an unintended third party may use the multifunction device 1.

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

On the other hand, in the operation example 6, by utilizing the mobile terminal 20, even if the user takes time in front of the multifunction device 1, the second approaching 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 the step 100 can be set relatively short. There is little risk that an unintended third party will use the multifunction device 1. As a result, the information manageability of the multifunction device 1 is maintained (the information manageability is improved if the convenience is equivalent to that of the operation example 5).

That is, in operation example 6, convenience can be improved while maintaining information management and energy saving.

<Second Embodiment>
~Overview~
In the first embodiment, when the first approaching state is detected, the mobile terminal is collated based on the identifier of the mobile terminal, and when the second approaching state is detected, the usage permission state is set. After making the usage permission state, make further preparations such as waking up from sleep.

In the second embodiment, the time from the first approach state detection to the second approach state detection is effectively utilized, and the specific advance preparation is started after the first approach state detection and before the second approach state detection. Specific advance preparation is preparation different from collation and license. Specific examples will be mentioned in the explanation of the control flow below.

The second embodiment is a modification of the first embodiment, and FIGS. 1 to 3 are referred to for the schematic configuration and the like.

~ Control flow ~
FIG. 8 is a control flow diagram showing advance preparation according to the second embodiment. The control flow in the case of utilizing the mobile terminal 20 (control peculiar to the present embodiment) will be described.

The communication control unit 18 of the multifunction device 1 is constantly searching for radio waves (short-range wireless communication) from the mobile terminal 20. Communication with the mobile terminal 20 is established, and the identifier of the mobile terminal 20 that has become able to communicate 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 or not it is registered in advance. Is determined (step S30). If the mobile terminal collation unit 33 determines that the collation does not match, the process returns to step S10.

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

It is preferable that the specific advance preparation does not include the preparation for making the operation / display panel 3 operable / displayable.

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

In step 40, 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 state in which the second approach state has not been detected has elapsed for a predetermined time (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.

When the predetermined time elapses in step S70, the control related to the cancellation of the specific advance preparation is performed, and the process returns to step S10. (Step S72).

When 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 considers that the user of the mobile terminal 20 is permitted to use the multifunction device 1. In the meantime, a license is granted (step S50).

The panel control unit 14 makes the operation / display panel 3 operable / displayable, and as soon as the specific advance preparation in step S32 is completed, the multifunction device 1 becomes usable (step S60).

The control flow when the mobile terminal 20 is not used (control as in the conventional case) is the same as that in the first embodiment.

~ Operation example ~
The operation of the user and the operation of the multifunction device will be described below.

Operation example 7 (basic operation of the second embodiment): An operation when the user uses the multifunction device 1 by utilizing the mobile terminal 20 will be described. The multifunction device 1 is constantly searching 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 the first approaching state is reached, the multifunction device 1 starts collation and specific advance preparation. When the user approaches further and stops moving in front of the multifunction device 1 (second approach state), the permission to use is automatically granted, and the operation / display panel 3 can be operated / displayed. .. As soon as the specific advance preparation is completed, the multifunction device 1 becomes usable (S10 → S20 → S30 → S32 → S40 → S70 → S40 → S50 → S60).

A screen related to the operation is displayed on the operation / display panel 3. The user performs an operation related to copying or the like via the operation / display panel 3.

Operation Example 8: An operation when a user carrying the mobile terminal 20 moves near the multifunction device 1 but does not use the multifunction device 1 (passing by) will be described. The multifunction device 1 is constantly searching for radio waves from the mobile terminal 20.

When the user carries the mobile terminal 20 and approaches the multifunction device 1, and the first approach state is reached, the multifunction device 1 starts collation and specific advance preparation. However, unless the second approach state is reached, the usage permission is not automatically granted, and the operation / display panel 3 cannot be operated / displayed. 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 released and the operation / display panel 3 is not activated.

If the specific advance preparation includes the preparation for making the operation / display panel 3 operable / displayable, in the operation example 8 (passing by), the operation / display panel 3 becomes operable / displayable. There is a risk of causing unnecessary confusion to a third party who was around the multifunction device regardless.

~effect~
By comparing the above operation examples, the effect according to the second embodiment will be described.

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

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

As described above, convenience can be further improved while maintaining information management and energy saving.

<Third Embodiment>
~Overview~
In the second embodiment, when the first approaching state is detected, the collation is performed and the specific advance preparation is started. On the other hand, in the third embodiment, after collation, the specific advance preparation is started based on the mobile terminal state information (details will be described later, see the description corresponding to FIG. 11).

~ Configuration / control ~
The third embodiment is a modification of the second embodiment (first embodiment), and the schematic configuration is based on 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 device 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 of the programs (apps) 26 stored in the mobile terminal 20 operate based on the information acquired from various sensors. Information from various sensors can be transmitted to the multifunction device 1 via the communication unit 21. As one of various applications, the operation application 27 of the multifunction device 1 is stored.

Next, a functional block diagram of the main control unit 10 of the multifunction device 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. The characteristic relationships between the main control units are indicated by arrows.

The mobile terminal status information detection unit 34 communicates with the mobile terminal 20 and detects the status information of the mobile terminal 20. When it is determined that the mobile terminal status information detection unit 34 has detected the status information of the mobile terminal 20, each unit of the main control unit 10 (for example, the power supply control unit 13) controls the start of the specific advance preparation (see the arrow in the figure). ..

FIG. 10 is a control flow diagram showing advance preparation according to the third embodiment. The difference from the control flow diagram showing the 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.

If the mobile terminal collation unit 33 determines in step S30 that the collation matches, the mobile terminal state information detection unit 34 determines whether or not the state information of the mobile terminal 20 has been detected (step S31).

When 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 the specific advance preparation (step S32). For example, the power control unit 13 releases the sleep state. The image reading control unit 15 prepares for scanning drive. The scanning image formation control unit 16 warms up the fixing device. After that, 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 does not perform the control related to the start of the specific advance preparation, and the mobile terminal second approach detection unit 35 2 It is determined whether or not the approaching state is detected (step S40).

The control after step S40 is the same as that of the second embodiment. The control flow when the mobile terminal 20 is not used (control as in the conventional case) is the same as that in the first embodiment.

~ Operation example ~
The operation of the user and the operation of the multifunction device will be described below.

Operation example 9 (use of operation application): An operation when the user uses the multifunction device 1 by using the operation application 27 will be described. The multifunction device 1 is constantly searching 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 trying to use the operation application 27. As a result, the status information of the mobile terminal is detected. When the first approaching state is reached, the multifunction device 1 starts collation and specific advance preparation. When the user approaches further and stops moving in front of the multifunction device 1 (second approaching state), the permission to use is automatically granted. As soon as the specific advance preparation is completed, the multifunction device 1 becomes usable (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 / display panel 3 by the operation application 27 without making the operation / display panel 3 operable / displayable.

Operation example 10 (operation application not used): An operation when a user carrying a mobile terminal 20 uses the multifunction device 1 without using the operation application 27 will be described. The multifunction device 1 is constantly searching 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, if the mobile terminal 20 is in a pocket or a bag, for example, the state information of the mobile terminal is not detected. When the first approaching state is reached, the multifunction device 1 starts collation. When the user approaches further and stops moving in front of the multifunction device 1 (second approach state), a license is automatically granted. Further, the sleep mode is released without pressing the power switch, and the multifunction device 1 is in a usable state (S10 → S20 → S30 → S31 → S40 → S70 → S40 → S50 → S60) (see operation example 2).

A screen related to the operation is displayed on the operation / display panel 3. The user performs an operation related to copying or the like via the operation / display panel 3.

~effect~
By comparing the above operation examples, the effect according to the third embodiment will be described.

Operation Examples 7 and 8 (second embodiment) and operation example 9 (third embodiment) are compared. In the second embodiment, it is premised that normal operation (operation example 7) is performed, but there is a possibility that malfunction (operation example 8) may occur temporarily. 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 it is highly probable that the user will use the multifunction device 1, the risk of malfunction is extremely low. As a result, energy saving is maintained.

When it becomes mainstream to use the multifunction device 1 by using the operation application 27 as in the operation example 9, the usefulness of the operation / display panel 3 is relatively reduced. 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 predetermined information that can be inferred that the user is likely to use the multifunction device 1 according to the state of the mobile terminal 20.

If the angle (posture) of the mobile terminal 20 continues to be within a predetermined range, it can be inferred that the mobile terminal 20 is being operated by the user.

When the user approaches the multifunction device 1 while operating the mobile terminal 20, it is highly probable that the user uses the multifunction device 1 by using the operation application 27. 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 status information.

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

When the user approaches the multifunction device 1 while operating the mobile terminal 20, it is highly probable that the user uses the multifunction device 1 by using the operation application 27. The brightness information is measured by the brightness sensor 25 of the mobile terminal 20 and transmitted to the multifunction device 1. The multifunction device 1 detects mobile terminal status information.

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

An acceleration history pattern that is clearly different from the acceleration history pattern caused by walking is set as a manifestation of intention to use the multifunction device. For example, the action of shaking the mobile terminal 20 from side to side several times is defined as a manifestation of intention to use the multifunction device.

It is highly probable that the user uses the operation application 27 to use the multifunction device 1 when the user expresses his / her intention through the mobile terminal 20 and approaches the multifunction device 1. The acceleration history pattern 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 status information.
