Japanese patent application No. 2018-053832 filed on Mar. 22, 2018, including description, claims, drawings, and abstract the entire disclosure is incorporated herein by reference in its entirety.
The present invention relates to a recognition system of a person carrying away an output matter of an image forming apparatus, a recognition method, and a non-transitory computer-readable storage medium storing a recognition program.
In a company office or the like, a system that enables a plurality of users to use an image forming apparatus by connecting a plurality of user terminals to the image forming apparatus such as a MFP (multi-function peripheral) or the like via a network is established.
However, when a user who executed a print job acquires a printed matter as an output matter of the image forming apparatus from a sheet discharge tray of the image forming apparatus, the user may erroneously carry away the other person's printed matter by a later print job discharged to the same sheet discharge tray along with the his own printed matter in some cases. In addition, in some cases, a user who executed a later print job may erroneously take the other person's printed matter by a former print job along with the his own printed matter without noticing that the other person's printed matter remains in the sheet discharge tray.
A technique for urging the user who carries away the other person's printed matter to return the printed matter to the other person as described above is discussed in Unexamined Japanese Patent Publication No. 2008-221626. That is, history information of a print job executed by a user who logs in the image forming apparatus is displayed, and a query message is notified to a person or the like who executed a print job for outputting printed matter to the same sheet discharge tray as a sheet discharge tray which the print job designated by the user as a query target out of the history information has been discharged. As a result, it is possible to retrieve the printed matter without displaying the history information of the other person's print job.
However, a person who did not execute the print job can also touch the printed matter placed on the sheet discharge tray. Therefore, a person who has a possibility of carrying away the other person's printed matter is not limited to the user who executed the print job, but all the persons positioned near the image forming apparatus may also take the other person's printed matter. There exists a problem that the technique described in Unexamined Japanese Patent Publication No. 2008-221626 fails to cope with a case where a person who carried away the other person's printed matter is not the user remaining in the history due to execution of the print job.
The present invention has been made to address such the problem. That is, it is possible to specify those who possibly carried away the other person's printed matter without omission and urge them to return or the like.
To achieve at least any one of the abovementioned objects, according to an aspect of the present invention, a recognition system a person carrying away output matter of an image forming apparatus, a recognition method, and a non-transitory computer-readable storage medium storing a recognition program a recognition program reflecting one aspect of the present invention comprises the followings.

The image reader 150 applies light from the light source to a document set in a predetermined reading position, photoelectrically converts the reflected light using the imaging device, and creates image data from the electric signal.
The image controller 160 performs a layout processing and a rasterizing processing of the print data included in the print job received by the communication unit 130 to create image data having a bitmap format.
The image former 170 has an image former 40, a fixing unit 50, a sheet feeder 60, and a sheet conveyor 70.
The image former 40 has imaging units 41Y, 41M, 41C, and 41K corresponding to toners of respective colors of Y (yellow), M (magenta), C (cyan), and K (black). The toner images formed by respective imaging units 41Y, 41M, 41C, and 41K on the basis of the image data through charging, exposure, and development processes are sequentially superimposed on the intermediate transfer belt 42 and are transferred onto the sheet 500 by the secondary transfer roller 43.
The fixing unit 50 has a heating roller 51 and a pressing roller 52 and heats and pressurizes the sheet 500 conveyed to a fixing nip between both rollers 51 and 52 to melt and fix the toner images on the surface of the sheet 500.
The sheet 500 onto which the toner images are fixed by the fixing unit 50 is discharged to the sheet discharge tray 190 as the printed matter (output matter).
The sheet feeder 60 has a plurality of sheet feeding trays 61 and 62 to feed the sheets 500 stored in the sheet feeding trays 61 and 62 to the downstream side conveyance path one by one.

The sheet conveyor 70 discharges the sheet 500 on which an image is formed to the sheet discharge tray 190. A sensor 191 for detecting the printed matter is arranged on the sheet discharge tray 190. The sensor 191 constitutes a detector along with the controller 110. The sensor 191 is, for example, a weight sensor and can detect whether or not there is the printed matter on the sheet discharge tray 190 on the basis of detection information on a weight detected by the sensor 191.
The function of the controller 110 will be described in details.
For example, user information regarding persons allowed to enter an office where the image forming apparatus 100 is disposed is registered in the memory 120. The user information includes, for example, (1) user ID, (2) authentication data, (3) name, (4) IP address or MAC address of mobile terminal, and (5) mail address of mobile terminal. In addition, the user information may also include a seat guide map in the user's office.
The specifying unit (specifier) 111 acquires information for specifying a user of the mobile terminal 300 paired with the communication unit 130 using a near field wireless system based on Bluetooth (registered trademark) or the like (hereinafter, referred to as “terminal information) via communication unit 130. The terminal information includes, for example, the IP address or the MAC address of the mobile terminal 300. The specifying unit 111 specifies a person who approaches the image forming apparatus 100 (hereinafter referred to as “particular person”) on the basis of the acquired terminal information. A condition for specifying the particular person is that a distance between the person and the image forming apparatus 100 becomes equal to or shorter than a predetermined threshold. In other words, the specifying unit 111 specifies the person whose distance to the image forming apparatus 100 is equal to or shorter than the predetermined threshold as the particular person. The predetermined threshold can be set to an arbitrary distance as the maximum distance to the image forming apparatus 100 considered necessary for making contact with the printed matter on the sheet discharge tray 190. The predetermined threshold may be set to different values for each image forming apparatus 100.
The specifying unit 111 may set the condition for specifying the particular person including both a condition that the distance between the person and the image forming apparatus 100 becomes equal to or shorter than the predetermined threshold, and a condition that a period of time during which the distance between the person and the image forming apparatus 100 is equal to or shorter than the predetermined threshold is equal to or larger than a predetermined threshold. The threshold regarding the period of time is set to an arbitrary value corresponding to the minimum time considered necessary for approaching the printed matter on the sheet discharge tray 190, taking out the printed matter from the sheet discharge tray 190, and receding from the image forming apparatus 100.
The distance to the image forming apparatus 100 is calculated by photographing an omnidirectional image obtained by overlooking the entire office where the image forming apparatus 100 is installed using a surveillance camera such as a fisheye lens camera provided on a ceiling and visually recognizing the omnidirectional image. The distance to the image forming apparatus 100 may be detected using a GPS (global positioning system) function of the mobile terminal 300 or may be detected by using an embedded acceleration sensor in combination.
The specifying unit 111 may specify the user of the mobile terminal 300 as the particular person whose distance to the image forming apparatus 100 is equal to or shorter than the predetermined threshold on the basis of a fact that the communication unit 130 and the mobile terminal 300 are paired with each other. The specifying unit 111 may specify the particular person using at least any one of authentication data when logging in the image forming apparatus 100, and a photographic image of the surveillance camera that photographs a range including the image forming apparatus 100. The authentication data may include authentication data for at least any one of user authentication by using an ID card or entering an ID and a password, face authentication, and voice authentication. The specifying unit 111 may specify the user included in the authentication data or the user specified by the authentication data as the particular person. In addition, the particular person may be specified by image recognition of the photographic image of the surveillance camera.
The specifying unit 111 stores information on the particular person in the memory 120 in association with the user information corresponding to the particular person registered in the memory 120 in advance. The information on the particular person includes the IP address, the MAC address, or the like of the mobile terminal 300 used by the particular person, a timing at which the particular person is specified, and a timing at which the particular person is no longer specified. The IP address or the like of the mobile terminal 300 included in the user information registered in advance are compared with the IP address or the like included in the information on the particular person. If they match, the information on the particular person and the registered user information are stored in the memory 120 in association with each other. Hereinafter, the information on the particular person, and the user information corresponding to the particular person will be collectively referred to as “information regarding the particular person”.
The information acquiring unit 112 acquires information regarding the particular person by reading it from the memory 120 on the basis of a user's instruction input to the manipulation display unit 140. This instruction is an instruction input by the user on a login screen when the user whose printed matter has been carried away logs in the image forming apparatus 100 through user authentication. Specifically, the instruction is an instruction for displaying a list of particular persons specified after executing the print job. The print job may be the last print job executed by the user specified on the basis of the authentication information in the user authentication. Note that a selection screen for allowing the user to select the print job whose printed matter has been carried away may be displayed such that the user can select the print job. The information acquiring unit 112 causes a list of the acquired information regarding the particular person to be displayed on the manipulation display unit 140. The list displayed on the manipulation display unit 140 includes, for example, a name of the particular person, a timing at which the user approaches the image forming apparatus (that is, a timing at which the particular person is specified), and a timing at which the user recedes from the image forming apparatus (that is, a timing at which the particular person is no longer specified) are displayed as the information regarding the particular person for each particular person. Note that a period of time for which the user approaches the image forming apparatus may be displayed in the list instead of the timing at which the user recedes from the image forming apparatus. The period of time for which the user approaches the image forming apparatus can be calculated on the basis of the timing at which the particular person is specified and the timing at which the particular person is no long specified. The information acquiring unit 112 may transmit the list of information regarding the acquired particular person to the mobile terminal 300 or the terminal 200 of the user who logs in the image forming apparatus 100 from the mobile terminal 300 or the terminal 200 through user authentication via the communication unit 130 and display the list.
The manipulation display unit 140 displays the list of information regarding the particular persons so that the user can select at least any of the information regarding the particular persons displayed on the list. As a result, any of the particular persons is designated by the user. In a case where the list of information regarding the particular persons is transmitted to the mobile terminal 300 or the terminal 200, at least any of the information regarding the particular persons displayed in the list is displayed such that the user can select it in the mobile terminal 300 or the terminal 200.
The recognizer 113 recognizes the particular person designated by the user by being selected by the user in the list of information regarding the particular persons, as a candidate who have carried away the printed matter of the user who logs in the image forming apparatus 100 (hereinafter, simply referred to as “candidate”). In a case where the list of information regarding the particular person is displayed on the mobile terminal 300 or the terminal 200, the recognizer 113 receives information regarding the particular person selected by the user via the communication unit 130. In this case, the recognizer 113 recognizes the particular person relating to the received information as the candidate who have carried away the printed matter of the user who logs in the image forming apparatus 100.
The recognizer 113 may recognize all the particular persons listed in the list of information regarding the particular persons as the candidates who have carried away the printed matter of the user logged in the image forming apparatus 100. In a case where the print job executed by the user logged in the image forming apparatus 100 is executed between a plurality of print jobs of another user, the recognizer 113 may recognize the other user among the particular persons listed in the list of information regarding the particular person as the candidate. This is because the printed matter by the print job executed between the print jobs of the same user could be erroneously carried away with a high probability. In addition, in a case where the print job executed by the user logged in the image forming apparatus 100 is executed between print jobs of another user who forms images on a predetermined number of pages or more, the recognizer 113 may recognize the other user among all the particular persons listed in the list of information regarding the particular person as the candidate. This is because the printed matter by the print job executed between print jobs for a relatively large number of pages could be erroneously carried away with a high probability. The predetermined number may be set to an arbitrary number considering a possibility of being carried away.
On the basis of the information regarding the particular person recognized as the candidate, the recognizer 113 acquires information necessary for notifying the candidates who have carried away the printed matter from the memory 120. The information necessary for notifying the candidate includes, for example, a name of the candidate, a mail address of the mobile terminal 300 carried by the candidate, and the like.
The message transmitter 114 constitutes a notificator along with the communication unit 130. The message transmitter 114 creates a message regarding a fact that the printed matter has been carried away on the basis of the information necessary for notifying the candidate acquired by the recognizer 113 and transmits the message to the candidate via the communication unit 130. The message regarding the fact that the printed matter has been carried away constitutes a message regarding a fact that the recording medium on which the image is formed by the image forming apparatus 100 has been carried away. The message regarding a fact that the printed matter has been carried away intercepted includes, for example, (1) a message inquiring whether or not you carry away the other person's printed matter, and (2) a request to deliver the printed matter to the user whose printed matter has been carried away. The “user whose printed matter has been carried away” included in the message of (2) is included in the information regarding the user whose printed matter has been carried away. The information regarding the user whose printed matter has been carried away includes, for example, a name, a position of the seat, and a seat guide map, of the user whose printed matter has been carried away.
The message regarding the fact that printed matter has been carried away include a message for asking for discard of the printed matter. For example, an instruction indicating that the printed matter is not necessary may be input by the user when the user selects the information regarding the particular person in the list of information regarding the particular person. In this case, the message regarding the fact that printed matter has been carried away is the message for asking for discard of the printed matter. Even when the user executes the same print job as the print job of the printed matter that is passed away, the message regarding the fact that the printed matter has been passed away may be regarded as the message for asking for discard of the printed matter.
In addition, the recognizer 113 may recognize the candidate and the user whose printed matter has been carried away as described below.
The recognizer 113 detects whether or not there is the printed matter on the sheet discharge tray 190 on the basis of a detection result of a weight of the printed matter using the sensor 191 arranged in the sheet discharge tray 190. In a case where the particular person specified by the specifying unit 111 while the printed matter is detected after the print job is executed, and the printed matter is then no longer detected is different from the user who executed this print job, the recognizer 113 recognizes the user who executed this print job as the user whose printed matter has been carried away. In addition, this particular person is recognized as the candidate.
In a case where the same print job as the already executed print job is executed while the printed matter on the sheet discharge tray 190 is not detected, the recognizer 113 recognizes the user who executed this print job as the user whose printed matter has been carried away. In this case, the message transmitter 114 notifies the message regarding the fact that the printed matter has been carried away including the information regarding the recognized user whose printed matter has been carried away to the candidate.
In a case where a new printed matter is detected on the sheet discharge tray 190 while no print job is executed, the recognizer 113 recognizes the user who executed the print job by which an image is formed on the newly detected printed matter on the basis of the detection result of the printed matter using the sensor 191. For example, the recognizer 113 compares the weight calculated on the basis of the sheet type or the number of copies set in the print setting included in the print job with the weight of the printed matter detected by the sensor 191. As a result, it is possible to specify the print job by which the image has been formed on the newly detected printed matter, and recognize the user who executed the print job. The recognizer 113 notifies the information on the candidates to the recognized user via the communication unit 130. In this case, the candidate may be the particular person specified when the new printed matter is detected.
In
In this case, the user A carries away the printed matter of the user B, and then notices that the user A carries away the other person's printed matter. The user A returns the printed matter of the user B to the sheet discharge tray 190. As a result, the printed matter of the user B remains. That is, (1) the user A executes the print job by transmitting the print job from the terminal A to the image forming apparatus 100. Then, (2) the user B executes the print job by transmitting the print job from the terminal B to the image forming apparatus 100. Then, (3) the user A goes to the sheet discharge tray 190 in order to take his own printed matter. Then, (4) the user A takes and comes back the printed matter of the user B as the other person, output on the same sheet discharge tray as well as his own printed matter, so that carrying away of the printed matter of the user B occurs. Then, (5) the user B notices that there is no printed matter of the user B in the sheet discharge tray 190. Then, (6) the user B acquires his own printed matter by executing the print job again. Then, (7) the user A notices that he carried away the printed matter of the user B as the other person, and returns the printed matter of the user B to the sheet discharge tray 190. In this case, since the user B has already acquired his own printed matter, (8) the printed matter of the user B remains in the sheet discharge tray 190.
(1) The user A executes the print job by transmitting the print job from the terminal A to the image forming apparatus 100. Then, (2) the user B executes the print job by transmitting the print job from the terminal B to the image forming apparatus 100. Then, (3) the user A goes to the sheet discharge tray 190 to take his own printed matter. Then, (4) the user A takes and come backs the printed matter of the user B as the other person, output in the same sheet discharge tray, as well as his own printed matter, so that carrying away of the printed matter of the user B occurs. Then, (5) the user B notices that his own printed matter does not exist in the sheet discharge tray 190.
Then, (6) the user B logs in the image forming apparatus 100, and instructs to display the list of information regarding particular persons specified after executing the print job on the login screen. As a result, the list of information regarding particular persons is displayed on the manipulation display unit 140. In the example of
The controller 110 may further have a function of notifying that there is the possibility of carrying away of the printed matter by the print job before the print job is executed to an executor of the print job (more specifically, the user who, for example, transmits the print job to the image forming apparatus).
In a case where the single print job is executed between other print jobs that form images on a predetermined number of pages or more, the controller 110 notifies that there is the possibility of carrying away of the printed matter formed the image and output by executing the single print job to the executor of the single print job before the single print job is executed. As a result, it is possible to alert the executor of the print job by notifying that there is the possibility of carrying away of the printed matter before execution of the print job.
In a case where the single print job is executed between other print jobs of the same user, the controller 110 notifies that there is the possibility of interception of the printed matter output by executing the single print job to the executor of the single print job. As a result, it is possible to alert the executor of the print job by notifying that there is the possibility of carrying away of the printed matter before execution of the print job.
The operation of the recognition system 11 will be described. Note that, since the recognition system 11 is integrated into the image forming apparatus 100 as described above, the operation of the recognition system 11 will be described as the operation of the image forming apparatus 100.
The print job is executed as the user transmits the print job from the terminal 200 or the mobile terminal 300 to the image forming apparatus 100.
The controller 110 acquires the terminal information of the mobile terminal 300 paired with the communication unit 130 using the near field wireless system (S101).
The controller 110 determines whether or not there is the person who approaches the image forming apparatus 100 (S102). That is, the controller 110 determines whether or not the particular person whose distance to the image forming apparatus 100 is equal to or shorter than the predetermined threshold has been specified.
The controller 110 repeatedly executes steps S101 to S102 if no particular person is specified (S102: NO).
If the particular person is specified (S102: YES), the controller 110 stores the particular person in the memory 120 (S103). Note that, even when the single particular person is specified, other particular persons are repeatedly specified by repeatedly executing steps S101 to S102.
Here, while steps S101 to S103 are processed, it is assumed that the other person carries away the printed matter. Then, the user who executed the print job notices that there is no printed matter, that is, the printed matter has been carried away erroneously.
The controller 110 executes user authentication in response to the request of user authentication from the user whose printed matter has been carried away (S104).
The controller 110 specifies the print job executed by the user from the authentication data. The controller 110 causes the manipulation display unit 140 to display the list of information regarding the particular persons specified after execution of the specified print job such that the user can select at least any one of the information regarding the particular persons (S105).
The controller 110 determines whether or not the information regarding particular persons is selected from the displayed list (S106).
If it is determined that the information regarding the particular person is not selected (S106: NO), the controller 110 repeatedly executes steps S105 to S106.
If it is determined that the information regarding the particular person is selected (S106: YES), the controller 110 acquires information regarding the selected particular person from the manipulation display unit 140 (S107).
The controller 110 recognizes the particular person selected from the information regarding the particular person as the candidate of the person who carried away the user's printed matter (S108).
The controller 110 transmits the message regarding the fact that the printed matter has been carried away to the candidate via the communication unit 130 (S109).
This embodiment has the following effects.
The person who approaches the image forming apparatus is specified, any of the specified persons is recognized as the candidate of carrying away the printed matter, and the message is notified to the candidate. As a result, it is possible to specify the person having a possibility of carrying away the other person's printed matter without omission, urge return of the printed matter, and the like.
In addition, the person designated by the user whose printed matter has been carried away out of the specified persons is recognized as the candidate, and the message is notified including information regarding the user whose printed matter has been carried away. As a result, it is possible to urge the person who has a high possibility of carrying away the printed matter to return the printed matter to an owner.
Further, the notification system is integrate into the image forming apparatus, and the condition for specifying the person who approaches the image forming apparatus is set for each image forming apparatus. As a result, it is possible to flexibly respond to an arrangement environment of the image forming apparatus, and suitably widen a range for specifying the person having the possibility of carrying away the printed matter.
Further, the person who has the distance to the image forming apparatus equal to or shorter than the predetermined threshold is specified as the man who approaches the image forming apparatus. As a result, it is possible to flexibly set the range for specifying the person having the possibility of carrying away the printed matter.
Further, the person who approaches the image forming apparatus is specified using any of the authentication data when logging in the image forming apparatus and the photographic image of the surveillance camera that captures the range including the image forming apparatus. As a result, it is possible to flexibly set a range of specifying the person having the possibility of carrying away the printed matter depending on the arrangement environment of the image forming apparatus.
Further, the person who approaches the image forming apparatus is specified using the authentication data when logging in the image forming apparatus by at least any one of face authentication and voice authentication. As a result, it is possible to flexibly cope with the method of specifying the person who has the possibility of carrying away the printed matter.
Further, the list of information regarding persons specified as the person who approaches the image forming apparatus is displayed such that at least any of the information on the list can be selected by the user. In addition, the person relating to the selected information is recognized as the candidate. As a result, it is possible to more easily specify the person who has high possibility of carrying away the printed matter.
Further, the person whose distance to the image forming apparatus is equal to or shorter than the predetermined threshold is specified as the person who approaches the image forming apparatus, and the list contains at least any of the timing at which the distance becomes equal to or shorter than the predetermined threshold and the period of time for which the distance is equal to or shorter than the threshold as information regarding the person. As a result, it is possible to appropriately specify the candidate by providing the additional information for specifying the candidate who has carried away the printed matter to the user.
Further, the list of information regarding the persons specified as approaching the image forming apparatus is transmitted to the terminal of the user who executed the print job, and the list is displayed on the terminal such that said user can select at least any of said information displayed on said list. In addition, the selected information is received from the terminal, and the person regarding the information is recognized as the candidate. As a result, it is possible to specify the person having the high possibility of carrying away the printed matter without occupying the image forming apparatus.
Further, the printed matter discharged to the sheet discharge tray is detected. The person specified while the printed matter is detected after the print job is executed, and the printed matter is then no longer detected is different from the user who executed this print job, the user who executed this print job is recognized as the user whose printed matter has been carried away. In addition, the person specified while the printed matter is detected after the print job is executed, and the printed matter is then no longer detected, is recognized as the candidate. As a result, it is possible to cope with the case where the user whose printed matter is carried away does not notice the fact that print patter is carried away.
In the case where the same print job as that already executed print job is executed while no printed matter is detected in the sheet discharge tray, the user who executed the print job is recognized as the user whose printed matter is carried away. As a result, it is possible to specify the user whose printed matter is carried away with high accuracy.
In the case where the new printed matter is detected while no print job is executed, the user who executed the print job for forming the image in the printed matter is recognized on the basis of the newly detected printed matter, and the person specified at the time of detection of the new printed matter is recognized as the candidate. In addition, the recognized user is notified of the message including information regarding the recognized candidate. As a result, it is possible to provide the material of determination for specifying the person who has carried away the other person's printed matter.
The information regarding the user included in the message notifying the candidates contains the seat guide map of the user. As a result, the user whose printed matter is carried away can more reliably receive the printed matter.
In the case where there is an instruction from the user that the printed matter on which the image is formed by the print job is not necessary, or in a case where the same print job as the print job is executed, the message indicating that discard of the printed matter is desired is notified. As a result, it is possible to cope with a case where the printed matter becomes unnecessary when the user has already printed the printed matter again or the like.
In the case where the print job of the user is executed between other print jobs for forming images on the predetermined number of pages or more, the fact that there is the possibility that the printed matter generated by the print job can be carried away is notified to the user before this print job is executed. As a result, it is possible to prevent carrying away of the printed matter in advance.
In the case where the print job from the user is executed between other print jobs from the same user, the fact that there is the possibility of carrying away the printed matter of the print job is notified to the user before the print job is executed. As a result, it is possible to prevent carrying away of the printed matter in advance.
