Description

The present invention relates to an image processing apparatus that returns from a power saving mode when a user is detected by a human sensor or the like, and a management apparatus, a method, or the like that changes a detection range of a user by the image processing apparatus.

In order to reduce power consumption, image processing devices such as multi-function peripherals perform power control to shift to a power saving mode that stops the power supply to part of the device when it is not used for a certain period of time. ing. Generally, the return from the power saving mode to the normal mode is performed when the user's operation on the operation panel of the device is detected, but in recent years, the human sensor is used to return the device to a certain degree of proximity. The method of making is becoming popular.

However, in the case where the human sensor detects the user, for example, there is a case where the user just visited to pick up the discharged sheet, and there is a case where it is not always necessary to return. As a technique for dealing with this problem, Patent Document 1 below discloses a technique for changing the detection range of the motion sensor depending on the optional configuration of the main body, the presence/absence of paper on the discharge tray, and the like.

By the way, when the image processing apparatus is independently arranged, the use of the technique of Patent Document 1 eliminates the unnecessary detection of the user by the motion sensor. However, when a plurality of image processing devices are arranged adjacent to each other, a user approaching for the purpose of using the adjacent image processing device may be unnecessarily detected. In other words, a user using one image processing apparatus is detected by a motion sensor of an adjacent image processing apparatus that the user does not intend to use, unnecessarily returning from the power saving mode and wasteful power consumption. There is a problem of consumption.

In Patent Document 2 below, in order to address the above-described problem, when a person is sensed in an overlapping area in which the detection areas of the motion sensors of a plurality of adjacent image forming apparatuses overlap, the usage priority held in advance is used. An image forming apparatus is disclosed in which only one of the image forming apparatuses is returned from the power saving mode according to (the remaining amount of consumables or the amount of replacement parts used).

JP, 2013-108821, A Japanese Unexamined Patent Publication No. 2016-093981

In the technique of Patent Document 2, a device that recovers from the power saving mode when a user is detected in the overlapping area is specified according to priority based on the remaining amount of consumables, the usage amount of replacement parts, and the like. Does not always match the device actually used by the user. Therefore, the device with the higher priority was returned from the power saving mode, but when the user uses another device, the device actually used by the user will be delayed in returning from the power saving mode and Power is wasted due to the restoration of the device. Further, in the technique of Patent Document 2, each device always maintains the sensitivity (detection range) of the human sensor in the normal state during the power saving mode, which causes a problem of high power consumption.

The present invention is intended to solve the above problems, and prevents a user detection unit that detects a user to recover from a power saving mode from erroneously detecting a user who uses another device adjacently arranged.

Hereinafter, various embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a diagram showing a configuration example of an image forming system 2 according to the first embodiment of the present invention. The image forming system 2 is configured by connecting a management server 10 as a management device according to the present invention and a plurality of image processing devices 30 to a network 3 such as a LAN (Local Area Network). Further, a user terminal 5 such as a PC (Personal Computer) is connected to the network 3.

The image processing apparatus 30 stores a copy job in which an image based on image data obtained by optically reading an original with a scanner is printed on recording paper, saves the image data of the read original as a file, and stores the read original. Jobs such as a scan job for transmitting image data as a file to the outside, a print job for printing an image based on the print data received from the user terminal 5 on recording paper, and a FAX job for transmitting and receiving image data according to a facsimile procedure. It is a so-called multi-function peripheral having a function of executing. Hereinafter, the image processing device 30 is also referred to as an MFP.

For example, the image processing apparatus 30 shifts from the normal mode to the power saving mode when a job is not executed and a non-operation state continues for a certain time or more in a standby state waiting for an operation from a user. The power saving mode is an operating state that consumes less power than the normal mode.

In the normal mode, the image processing apparatus 30 is supplied with power to each unit of the image processing apparatus 30 and can execute various jobs. On the other hand, in the power saving mode, most parts except the part related to the job receiving function and the user detection unit 45 (see FIG. 5) that detects the approach of the user to return from the power saving mode to the normal mode are included. Power supply is off. In the power saving mode, a job such as a print job can be received from the outside but the job cannot be executed. Also, the display of the operation panel is turned off.

The user detection unit 45 has a function of detecting a human body within a detection range, like an infrared sensor. The detection range of the user detection unit 45 can be changed. In the image forming system 2, each image processing device 30 changes the detection range of the user detection unit 45 based on the instruction from the management server 10.

More specifically, the management server 10 communicates with each image processing apparatus 30 to acquire operating state information indicating the operating state of each image processing apparatus 30, and always recognizes the operating state of each image processing apparatus 30. .. The management server 10 also includes a storage unit (installation position storage unit 15b in FIG. 4) that stores installation position information and the like of each image processing device 30, and each image processing device 30 is installed independently from this information. It is recognized whether or not the image processing device 30 is placed adjacent to another image processing device 30. Then, the detection range of the user detection unit 45 included in the image processing apparatus 30 to which the other image processing apparatus 30 is arranged is set to the operating state of the other image processing apparatus 30 to be arranged adjacent to the image processing apparatus 30. Change accordingly.

For example, as shown in FIG. 2, when the first image processing apparatus 30 (MFP1) and the second image processing apparatus 30 (MFP2) are arranged adjacent to each other and both are in the power saving mode, The detection ranges D1 and D2 of the user detection units 45 of the MFP1 and MFP2 are set to predetermined standard ranges (normal ranges), respectively. In the example of FIG. 2, when the detection range is set to the standard range, a part of the MFP 2 is included in the detection range D1 of the MFP 1. Therefore, the user detection unit 45 of the MFP 1 may erroneously detect the hand of the user who operates the MFP 2 or removes the printed matter from the discharge tray of the MPF 2.

It is considered that the user operates the MFP 2 or removes the printed matter from the discharge tray when the user inputs a job to the MFP 2 or removes the printed matter output by executing the job. Therefore, in the image forming system 2 according to the present invention, the operating state of the MFP 2 is the state in which the job is being received, the job is being executed, the state before the printed matter is removed after the print job is executed, or the normal mode in which the power saving mode is restored. In such a case, as shown in FIG. 3, the detection range D1 of the MFP 1 is made narrower than the standard range so that the user detecting unit 45 of the MFP 1 does not erroneously detect a user who operates the MFP 2 or the like. ..

Specifically, in the image forming system 2, the detection range is changed in the following sequence. Initially, it is assumed that the adjacent MFPs 1 and 2 are both in the power saving mode and the detection ranges are both set to the standard range. In this state, when the MFP 2 receives the print job from the user terminal 5 via the network 3 (P1 in FIG. 1), the MFP 2 is in the operating state of receiving (or receiving) the print job. The management server 10 is notified (transmitted) of the operating status information indicating (1) (P2 in FIG. 1).

Upon receiving this notification, the management server 10 instructs the MFP 1 adjacent to the MFP 2 to change the detection range D1 to the first range narrower than the standard range (FIG. 1, P3). Upon receiving the instruction, the MFP 1 changes the detection range D1 to the first range narrower than the standard range, as shown in FIG.

The MFP 2 executes the print job received from the user terminal 5 and also notifies the management server 10 of the operating state of its own device every time the operating state changes (or periodically). Specifically, printing start, printing in progress, printing end, removal of printed matter, and the like are sequentially notified as operating states. When the management server 10 receives a notification from the MFP 2 that the removal of the printed matter is completed (P4), it instructs the MFP 1 to return the detection range D1 to the standard range (P5). Upon receiving the instruction, the MFP 1 returns the detection range D1 to the standard range (state shown in FIG. 2).

When the MFP 1 receives the job, the detection range of the MFP 1 is set according to the operating state of the MFP 1 regardless of the operating state of the adjacent MFP 2. For example, when a confidential print print job that starts printing on condition that the user is authenticated by the image processing apparatus 30 is transmitted to the MFP 1 in the power saving mode, the MFP 1 receives the print job without returning from the power saving mode. And hold. When the MFP 1 receives the print job, it is assumed that thereafter, the user comes to the MFP 1 to perform an operation such as user authentication in order to execute the print job. Therefore, after receiving the print job, the MFP 1 controls the detection range of the MFP 1 according to the operating state of the MFP 1 itself, regardless of the operating state of the image processing apparatus adjacently arranged. For example, the detection range of the MFP 1 is set to the standard range and the arrival of the user is waited for.

The information on the installation position may be any information that allows the image processing devices 30 adjacent to each other to be recognized. For example, it may be information that directly indicates that the MFP 1 and the MFP 2 are adjacently arranged, information that indicates a relative positional relationship between the MFP 1 and the MFP 2 that are adjacently arranged, map information that indicates a layout in the office, and the like.

In addition, it is preferable that the information regarding the installation position includes information indicating the model name of each image processing device 30, the installation direction, and the like. The model name is used to recognize the position of the paper discharge tray and the position of the operation panel in the image processing apparatus 30. Instead of the model name or together with the model name, the installation position information may include information itself indicating the position of the discharge tray or the position of the operation panel in the image processing apparatus 30.

The information indicating the installation direction of the image processing device 30 is arranged side by side, for example, when the MFP 1 and the MFP 2 are installed back to back, even when the MFP 1 and the MFP 2 are installed adjacent to each other. This is important since it is completely different from which part of the MFP 2 the detection range of the MFP 1 overlaps.

The method by which the management server 10 acquires the information regarding the installation position may be arbitrary. An administrator or the like may register it in the management server 10, or each image processing apparatus 30 may notify the management server 10 of the orientation, position, model name, etc. of its own apparatus.

The network communication unit 41 has a function of communicating with the management server 10, the user terminal 5, and other external devices through the network 3.

The operation panel 42 includes an operation unit 43, a display unit 44, a user detection unit 45, and the like. The display unit 44 includes a liquid crystal display or the like and displays various screens such as an operation screen and a setting screen. The operation unit 43 is configured by a numeric keypad, hard keys such as a start button and a stop button, and a touch screen provided on the display surface of the liquid crystal display.

The user detection unit 45 detects a human body in the set detection range. For example, as shown in FIG. 6, the user detection unit 45 is configured to include human sensor 45a to 45d provided on each of the four sides forming the outer peripheral portion of the substantially rectangular operation panel 42. The human presence sensors 45a to 45d each have a directivity directed to the outside of the operation panel 42. The sensitivities of the human presence sensors 45a to 45d can be adjusted (increased or decreased) individually, whereby the detection range of the user detection unit 45 can be adjusted to any shape and any width.

Note that the user detection unit 45 is not limited to the human presence sensors 45a to 45d, and may be configured with more sensors so that the shape and width of the detection range can be adjusted more finely. The user detection unit 45 may be provided in a place other than the periphery of the operation panel 42.

Further, as the user detection unit 45, a configuration may be used in which a camera that captures the image processing device 30 and its surroundings is installed and an image output from the camera is analyzed to detect the user. In this case, when changing the detection range, the shooting range itself by the camera may be moved, or the camera always shoots a wide range beyond the maximum range that can be set as the detection range, and a specific area in the image May be the detection range for detecting the user.

The detection range in the present invention is a range in which user detection is effective. The detection range does not have to match the actual shooting range of the camera or the range in which the motion sensor detects a person, and may be a part thereof. For example, switching valid/invalid of user detection by the user detection unit 45 is included in the change of the detection range. Disabling detection is equivalent to changing the effective detection range to zero.

FIG. 7 shows an example of changing the detection range. The figure (a) shows the standard range, the figure (b) shows the detection range (similar to the standard range) when the sensitivity is uniformly reduced and narrowed in each direction, and the figure (c) shows the sensitivity lowered in a specific direction. The example of the detection range in the case is shown.

The image processing device 30 can also set the detection range to the following range. For example, from the standard range, a range in which a user who removes the discharge tray portion or the discharge tray portion of the image processing apparatus 30 adjacently arranged and the printed matter placed on the discharge tray are assumed to pass the user's hand The excluded area is set as the detection range. Further, with respect to the standard range, the original document is set on the portion of the automatic document feeder 35 of the image processing apparatus 30 or the portion of the automatic document feeder 35 and the original plate of the automatic document feeder 35 which are arranged adjacent to each other, or the original is discharged. The detection range is an area excluding a range that is supposed to pass the user's hand when removing a document from the tray. In addition, the detection range is excluded from the standard range in a range excluding a specific part such as a part of the operation panel 42, a part accessed by the user when exchanging consumables, and a part accessed by the user when a paper jam occurs. You can change the setting.

The detection range instructing unit 22 is information indicating the positional relationship between adjacent image processing devices 30, the orientation of each image processing device 30, and the position in the image processing device 30 of a predetermined location accessed by the user when executing a job. Based on the installation position information stored in the installation position storage unit 15b, the detection range is set so as not to detect a user who accesses the image processing device 30 adjacently arranged.

In the example of FIGS. 2 and 3 described above, when the detection range of the MFP 1 is narrowed between the time when the MFP 2 receives the job and the time when the printed matter is removed from the discharge tray of the MFP 2, a change in the operating state of the MFP 2 occurs. Accordingly, the detection range of the MFP 1 may be changed more finely.

For example, the detection range is changed to the first range which is narrower than the standard range during the period from the reception start of the print job to the start of printing, and the detection range is narrowed to the second range narrower than the first range during printing based on the print job. The range is changed, and the detection range is set to the third range, which is narrower than the second range, between the completion of printing and the time when the printed matter remains in the paper ejection tray (until the paper is removed from the paper ejection tray). The third range is a range excluding a part of the paper discharge tray and a range predicted to be passed by a user who removes the printed matter placed on the paper discharge tray.

Further, the setting of the third range is continued until a predetermined period elapses after the printed matter detection sensor provided on the paper discharge tray detects the removal of the printed matter. That is, after the printed matter detection sensor detects that the printed matter has been removed from the output tray, the user's hand who removes the printed matter waits for a time that is supposed to go out of the standard range, and then the detection range becomes standard. Control to return to the range.

Similarly, when the adjacent image processing device 30 executes a job for reading a document by using the automatic document feeding device 35, the detection range is changed according to the change in the operating state accompanying the progress of the job. For example, consider a case where the user sets a document on the MFP 2 and performs a copy job when the adjacent MFPs 1 and 2 are both in the power saving mode. When a document is set on the automatic document feeder 35 of the MFP 2, the detection range of the MFP 1 is changed so that the automatic document feeder 35 of the MFP 2 and the operation panel 42 are excluded from the detection range.

After that, when the reading of the document is completed, the detection range of the MFP 1 is changed to the above-mentioned third range that does not include the discharge tray of the MFP 2. The detection range of the MFP 1 is returned to the standard range after a lapse of a predetermined time after the original and the printed matter are removed.

In order to prevent erroneous detection of the user who sets the original document on the MFP 2 before the user detection unit 45 of the MFP 1 narrows the detection range, the behavior of the user from the approaching user's movement, which will be described later, will be described. When it is predicted that the user's hand will face the automatic document feeder 35 of the MFP 2 or the document cover, the detection range of the MFP 1 may be narrowed to a range excluding the automatic document feeder 35 and its periphery from the standard range. In this case, the above erroneous detection can be prevented.

FIG. 8 shows the processing performed by the management server 10. Here, a case where one image processing device 30 in which another image processing device 30 is adjacently arranged is focused and the detection range of the one image processing device 30 is controlled will be described as an example. In the description of the flowcharts of FIG. 8 and subsequent figures, another image processing device 30 arranged adjacently is taken as an adjacent device, and one image processing device 30 of interest is taken as a device of interest. In the initial state, the device of interest is in the power saving mode and has not received any job.

The management server instructs the device of interest to set the detection range to the standard range (step S101). Next, the management server 10 determines whether or not the adjacent device is in operation based on the operation state information of the adjacent device acquired by the operation information acquisition unit 21 (step S102). Here, “in operation” refers to the case where the job is received in the normal mode or the power saving mode.

If the adjacent device is not in operation (step S102; No), the management server 10 determines whether or not the device of interest is in operation based on the operation state information acquired by the operation information acquisition unit 21 from the device of interest (step S102). S103), if the device of interest is not in operation (step S103; No), the process returns to step S102. If the device of interest is in operation (step S103; Yes), the management server 10 waits for the device of interest to end operation (state out of the in-operation state) (step S109; No), and the device of interest operates. When it is completed (step S109; Yes), the process returns to step S101.

If the adjacent device is in operation (step S102; Yes), the management server 10 confirms the operation content (detailed state in operation) of the adjacent device based on the operation state information acquired by the operation information acquisition unit 21. (Step S104). The management server 10 decides how to narrow the detection range of the device of interest according to the result of the confirmation (the operation content of the adjacent device), and sets the device of interest to change the detection range to the decided range. Instruct (step S105).

After that, the management server 10 determines whether or not the device of interest is operating based on the latest operating state information regarding the device of interest acquired by the operation information acquisition unit 21 (in particular, whether a print job or the like has been received during the power saving mode). Is confirmed (step S106). If the device of interest is not in operation (step S106; No), the management server 10 determines whether or not the operation of the adjacent device has ended (step S107), and the state of operation continues instead of end of operation. If so (step S107; No), the process returns to step S104 to continue the process. When the operation of the adjacent device has ended (step S107; Yes), the management server 10 returns to step S101 and continues the process.

When the device of interest is in operation (step S105; Yes), the management server 10 instructs the device of interest to return the detection range of the device of interest to the standard range (step S108), and proceeds to step S109 for processing. continue.

The job executed while the device of interest or the adjacent device is operating is not limited to the print job, and may be any job such as a scan job, a copy job, or a FAX job.

FIG. 9 shows the details of step S105 in FIG. 8 when the job executed while the adjacent apparatus is operating is a print job. In the process of FIG. 9, the detection range of the device of interest is adjusted to the optimum range in a series of processes such as reception of a print job, start of print operation, end of print output, and removal of paper from the discharge tray.

The management server 10 analyzes the operation content of the adjacent device based on the operation state information acquired from the adjacent device in step S104 of FIG. 8 (step S201). As a result of the analysis, if the adjacent device is receiving the print data (print job) (step S202; Yes), the management server 10 instructs the device of interest to set the detection range to the standard range (step S203). ), and ends this processing.

If the adjacent device is not receiving the print data (print job) (step S202; No), the management server 10 determines whether the adjacent device is in the print start state for the print job (step S204). .. When the adjacent device is in the print start state for the print job (step S204; Yes), the management server 10 instructs the device of interest to set the detection range to 80% of the standard range (step S205). , This process ends. The detection range is narrowed to 80% in consideration of the possibility that a user who has sent a print job to an adjacent device to print it will arrive at the adjacent device earlier.

If the adjacent device is not in the print start state for the print job (step S204; No), the management server 10 determines whether or not the adjacent device is outputting the printed matter for the print job (discharging to the discharge tray). Is determined (step S206). If the adjacent device is outputting the printout related to the print job (step S206; Yes), the management server 10 instructs the device of interest to set the detection range to 60% of the standard range (step S207), The process ends. The detection range is further narrowed to 60% of the standard range in advance so as to avoid erroneous detection when the user arrives at the adjacent device.

If the adjacent device is not outputting the printed matter related to the print job (discharging to the discharge tray) (step S206; No), the management server 10 waits within a certain time after the adjacent device finishes the printing related to the print job. (Step S208). When it is within a certain time after the adjacent device finishes the printing related to the print job (step S208; Yes), the management server 10 sets the detection range of the device of interest to 30% of the standard range (minimum range). (Step S209), and this processing ends. By significantly narrowing the detection range, it is possible to prevent erroneous detection when the user arrives at the adjacent device and takes out the printed matter from the output tray.

When a certain period of time has passed since the adjacent device finished printing the print job (step S208; No), the management server 10 determines whether or not the printed matter remains in the discharge tray and is left alone. Is determined (step S210). When the printed matter is left unattended in the adjacent device (step S210; Yes), the management server 10 instructs the device of interest to set the detection range to 50% of the standard range (step S211), and this process is executed. finish. When the user does not come to pick up the printed matter placed on the discharge tray of the adjacent device for a long time, the detection range of the device of interest is expanded by one step from the minimum range to improve the usability.

When the adjacent device is not in the abandoned state (step S210; No), the management server 10 instructs the device of interest to set the detection range to the standard range (step S212), and ends this processing.

FIG. 10 shows details of another processing example of step S105 of FIG. In the processing of FIG. 10, the behavior (orbit) of the hand when the user takes out the printed matter from the sheet ejection tray in the state where the printed matter remains in the sheet ejection tray of the adjacent device is calculated from the detection states of a plurality of motion sensors or the like. Then, the detection range of the device of interest in standby is adjusted. For example, the process of FIG. 10 is effective in the case where the user approaches with the printed matter left unattended for a long time after printing is completed by the adjacent device.

The management server 10 analyzes the operation content of the adjacent device based on the operation state information acquired from the adjacent device in step S104 of FIG. 8 (step S301). As a result of the analysis, when the adjacent device does not detect the approach of the user (step S302; No), the management server 10 instructs the device of interest to set the detection range to the standard range (step S303), This process ends.

When the user is approaching the adjacent device (step S302; Yes), the management server 10 determines whether or not the printed matter is placed on the discharge tray of the adjacent device (step S304). When the printed matter is not placed on the discharge tray of the adjacent device (step S304; No), the management server 10 instructs the device of interest to set the detection range to 80% of the standard range (step S305). ), and ends this processing. The detection range is narrowed in consideration of the behavior of the user who approaches the adjacent device.

When the printed matter is placed on the discharge tray of the adjacent device (step S304; Yes), the management server 10 determines the future behavior (trajectory) of the user's hand from the detection states of the plurality of sensors of the adjacent device. It is determined whether it is specified (predictable) (step S306). For example, if it is detected that the user's hand approaching from the front of the adjacent device is moving toward the right part of the adjacent device, the operation part on the right part of the adjacent device, If it is on the right side of the apparatus, it is determined that the user's hand is heading toward the paper ejection tray.

When the behavior (trajectory) of the user's hand in the future cannot be specified (step S306; No), the management server 10 instructs the device of interest to set the detection range to 60% of the standard range (step S307). , This process ends. By setting the detection range to 60% of the standard range, erroneous detection will be reduced under conditions where future user's hand behavior cannot be specified.

When the behavior (trajectory) of the user's hand in the future can be specified (step S306; Yes), the management server 10 determines whether or not the behavior (trajectory) of the specified user's hand passes near the device of interest. (Step S308). When the predicted behavior of the user's hand does not pass near the device of interest (step S308; No), the management server 10 instructs the device of interest to set the detection range to 50% of the standard range ( In step S309), this process ends. By setting the detection range of the device of interest to 50% of the standard range, it is possible to prevent erroneous detection when the user takes out a printed material from the discharge tray of the adjacent device and to ensure the usability of the device of interest.

When the predicted user's hand behavior passes near the device of interest (step S308; Yes), the management server 10 instructs the device of interest to set the detection range to 30% of the standard range (step S308). S310), and this processing ends. Since the user of the adjacent device is operating in a close range to the device of interest, by setting the detection range of the device of interest to 30% of the standard range (minimum range), the user can print from the discharge tray of the adjacent device. Maximize the effect of preventing false detection of the action of taking out.

In addition to changing the detection sensitivity, the shape of the detection range may be changed so that the region predicted to be passed by the user is outside the detection range.

When there is a user approaching an adjacent device, the hand behavior of the user is detected by multiple sensors and the future hand behavior is predicted, and the predicted hand behavior (trajectory) is excluded. The use of the method of changing the detection range of the device of interest is not limited to the case where the printed matter remains in the discharge tray. For example, when it can be predicted that the user's hand approaching the adjacent device is heading toward the automatic document feeder 35 of the adjacent device, the automatic document feeder 35 of the adjacent device is set to be out of the detection range. The detection range of the device of interest may be set. Further, when it can be predicted that the hand of the user approaching the adjacent device is heading toward the operation panel 42 of the adjacent device, the operation panel 42 of the adjacent device is detected to be out of the detection range. Just set the range.

FIG. 11 shows the details of another processing example performed in step S105 of FIG. In the process of FIG. 11, the detection range of the device of interest is adjusted according to the location where the user operates the adjacent device, the remaining amount of consumables in the adjacent device, the occurrence of paper jam, and the like. Here, the adjoining device uses, as the operation information, whether or not the user is operating the operation panel 42 of the own device, whether or not the user is operating the automatic document feeder 35 or the document cover, the remaining amount of consumables, and the paper. That is, the management server 10 is notified of the presence/absence of information, and information about the location.

The management server 10 analyzes the operation content of the adjacent device based on the operation state information acquired from the adjacent device in step S104 of FIG. 8 (step S401). As a result of the analysis, when the adjacent device does not detect the approach of the user (step S302; No), the management server 10 instructs the device of interest to set the detection range to the standard range (step S303), This process ends.

When the user is approaching the adjacent device (step S402; Yes), the management server 10 determines whether the user is operating the operation panel 42 of the adjacent device (step S404). When the user is operating the operation panel 42 of the adjacent device (step S404; Yes), the management server 10 sets the range in which the operation panel 42 of the adjacent device and its vicinity are excluded from the standard range of the focused device as the detection range. (Step S405), the present process is terminated. By setting the operation panel 42 of the adjacent device outside the detection range, it is possible to prevent the target device from erroneously detecting the operation of the user who operates the operation panel 42 of the adjacent device.

When the user is not operating the operation panel 42 of the adjacent device (step S404; No), the management server 10 determines whether the user is operating the automatic document feeder 35 or the document cover of the adjacent device (step S404). S406). When the user is operating the automatic document feeder 35 or the document cover of the adjacent apparatus (step S406; Yes), the management server 10 causes the focused apparatus to move from the standard range to the automatic document feeder 35 of the adjacent apparatus or the document cover and the vicinity thereof. It is instructed to set the range excluding () as the detection range (step S407), and this processing ends. The detection range is narrowed in consideration of the behavior of the user who approaches the adjacent device. By making the automatic document feeder 35 and the document cover of the adjacent device out of the detection range, it is possible to prevent the target device from erroneously detecting the operation of the user who operates the automatic document feeder 35 and the document cover of the adjacent device.

When the user is not operating the automatic document feeder 35 or the document cover of the adjacent device (step S406; No), the management server 10 determines whether or not the adjacent device is out of consumables (step S408). If the adjacent device is out of consumables (step S408; Yes), the management server 10 detects a range excluding the part operated by the user at the time of exchanging the consumable and the vicinity thereof from the standard range of the device of interest. To instruct the setting (step S409), and this processing ends. Prevents the target device from erroneously detecting the user's operation of exchanging or replenishing consumables with the adjacent device by setting the part of the adjacent device that is operated when exchanging or replenishing the corresponding consumables to be outside the detection range. To do.

If the adjacent device is not out of consumables (step S408; No), the management server 10 determines whether a paper jam has occurred in the adjacent device (step S410). If a paper jam has occurred in the adjacent device (step S410; Yes), the management server 10 detects a range in which the device of interest and the vicinity thereof are excluded from the standard range of the focused device. An instruction is issued to set the range (step S411), and this processing ends. By setting the portion operated by the user to eliminate the paper jam in the adjacent device outside the detection range, it is possible to prevent the target device from erroneously detecting the user who performs the work for removing the paper jam in the adjacent device.

When there is no paper jam in the adjacent device (step S410; No), the management server 10 operates the adjacent device to operate the operation panel, the automatic document feeder 35, the document cover, and the consumables. Then, an instruction is issued to set a range excluding the part operable by the user other than the part operated to clear the paper jam from the standard range as the detection range (step S412), and the process is terminated. By setting the assumed user operation position outside the detection range, it is possible to prevent the target device from erroneously detecting the operation of the user who operates the adjacent device.

In the process of FIG. 11 as well, a method may be adopted in which the behavior of the hand of the user approaching the adjacent device is detected by a plurality of sensors and the future behavior of the hand is predicted. That is, before the user actually operates the operation panel of the adjacent device, it is determined whether or not the operation panel of the adjacent device is operated, and the operation panel of the adjacent device is excluded from the detection range of the device of interest. The determination of “is the operation panel being operated” in step S404 of FIG. 11 may be “whether the operation of the operation panel is predicted from the behavior of the user”. In steps S406, S408, and S410, the same prediction may be used.

As described above, in the image forming system 2 according to the first embodiment, the user who operates the other image processing apparatus 30 to which the other image processing apparatus 30 is adjacently arranged is erroneous. It is prevented to detect and uselessly return from the power saving mode to the normal mode. In addition, the detection range of the user detection unit 45 of the adjacent image processing apparatus 30 is narrowed according to the operating state of the adjacent image processing apparatus 30. The power consumption required for detection can be reduced as compared with the case where the detection range is always set to the standard range in the mode.

Further, since the detection range of each image processing device 30 is collectively controlled by the management server 10, other image processing devices 30 are arranged adjacent to each other without placing a heavy load on the hardware and software of each image processing device 30. It is possible to realize control for changing the detected range of the image processing apparatus 30 that has been selected according to the operating state of another image processing apparatus 30 that is adjacently arranged.

Next, a second embodiment of the present invention will be described.

In the second embodiment, the management server 10 is not provided, and each image processing device 30 makes the determination made by the management server 10. The system configuration in the second embodiment may be the one without the management server 10 in FIG.

FIG. 12 is a block diagram showing a schematic configuration of the image processing device 30B according to the second embodiment. The same components as those of the image processing apparatus 30 shown in the first embodiment are designated by the same reference numerals and the description thereof will be omitted.

The CPU 31 of the image processing apparatus 30B fulfills the functions of the operating state information notifying unit 55, the operating state information acquiring unit 56, and the detection range setting unit 57. The operating status information notifying unit 55 notifies the other image processing apparatus 30B adjacently arranged of the operating status information indicating the operating status of the own apparatus. The operating status information acquisition unit 56 acquires operating status information from another image processing apparatus 30B adjacently arranged. The detection range setting unit 57 changes the detection range of the user detection unit 45 of its own device. The detection range setting unit 57 performs the same process as the detection range instructing unit 22 in the management server 10 on the user detection unit 45 of its own device.

In the second embodiment, each image processing apparatus 30 inquires and obtains the position, orientation, and model name of each image processing apparatus 30 via the network 3, and obtains the location, orientation, and model name of its own apparatus. By comparing with, the positional relationship between the image processing device 30 adjacent to the own device and the own device is recognized. The nearby image processing device 30 may be recognized by using near field communication or the like.

In the second embodiment, for example, when the MFP 1 and the MFP 2 are arranged adjacent to each other as shown in FIG. 2, the control of the detection range is performed as follows. Initially, it is assumed that the adjacent MFPs 1 and 2 are both in the power saving mode and the detection ranges are both set to the standard range. When the MFP 2 receives a print job from the user terminal 5 via the network 3 in this state, the MFP 2 notifies the MFP 1 that the print job is being received (or has been received) as the operating state of the own apparatus.

Upon receiving this notification, the detection range setting unit 57 of the MFP 1 changes the detection range D1 of the user detection unit 45 of its own device to a range narrower than the standard range. The MFP 2 executes the received print job and notifies the MFP 2 of the operating state of its own device every time the operating state changes. Upon receiving the notification from the MFP 2 that the removal of the printed matter is completed, the MPF 1 returns the detection range D1 to the standard range.

In addition, the detection range setting unit 57 controls the detection range of the user detection unit 45 of the own device, similarly to the control (the control shown in FIGS. 8 to 11 and the like) performed by the management server 10 in the first embodiment.

Also in the image processing apparatus 30B of the second embodiment, similarly to the first embodiment, the user operating the adjacent image processing apparatus 30B is erroneously detected and wasted from the power saving mode to the normal mode. Return is prevented. Further, the detection range of the user detection unit 45 of the own device is narrowed according to the operating state of the image processing devices 30B arranged adjacent to each other. Power consumption required can be reduced.

Further, in the second embodiment, the above function can be realized without providing a dedicated server.

Although the embodiments of the present invention have been described above with reference to the drawings, the specific configurations are not limited to those shown in the embodiments, and there are changes and additions within the scope not departing from the gist of the present invention. Also included in the present invention.

In the embodiment, the example in which the number of adjacent image processing devices 30 is one has been described. The invention applies. The detection range of the MFP 1 may be changed based on the operating states of the MFP 2 and the MFP 3.

The power saving mode may have a plurality of levels of different power consumption. In this case, the detection of the return by the user detection unit 45 is preferably used when returning from the power saving mode of the level with the lowest power consumption to another level.
