  The communication unit 6 is a communication interface device that communicates with the server device 8 via the network 80. The control unit 5 performs all transmission and reception of data with the server device 8 through the communication unit 6.

  The secondary storage unit 7 is a computer-readable non-volatile data storage device. The secondary storage unit 7 can store programs and various data. For example, a combination of one or both of a hard disk drive and a solid state drive (SSD) is employed as the secondary storage unit 7.

  The image reading unit 1 is a device that executes a reading process for reading an image of a document 91. The image reading unit 1 includes a light source 1a, a scanning mechanism 1b, an image sensor 1c, an AFE (Analog Front End) 1d, and the like.

  The light source 1 a emits light to the document 91. The scanning mechanism 1b causes the light of the light source 1a to scan the original 91. The image sensor 1c receives the reflected light from the original 91 and outputs a detection signal of the amount of received light as an image signal.

  The AFE (1d) converts the image signal into digital image data. In the following description, an image read from the document 91 by the reading process of the image reading unit 1 is referred to as a read image. The image data representing the read image, that is, the image data output by the image reading unit 1 is referred to as read image data.

  The image forming unit 2 is an apparatus that forms an image on the sheet 92 by a predetermined method such as an electrophotographic method or an inkjet method. In the present embodiment, the image forming unit 2 executes a printing process for forming the read image on the sheet 92.

  For example, when the image forming unit 2 is a device that executes the printing process by an electrophotographic method, the image forming unit 2 includes a sheet conveying mechanism 2a, a photoconductor 2b, a charging device 2c, a laser scanning unit 2d, a developing device 2e, A transfer device 2f and a fixing device 2g are provided.

  The sheet transport mechanism 2a transports the sheet 92 along a predetermined route. The charging device 2c charges the surface of the photoconductor 2b. The laser scanning unit 2d writes an electrostatic latent image on the charged surface of the photoconductor 2b.

  The developing device 2e develops the electrostatic latent image on the photoconductor 2b into a toner image. The transfer device 2f transfers the toner image on the photoconductor 2b to the sheet 92. The fixing device 2g fixes the toner image on the sheet 92 by heating the toner image on the sheet 92. In the following description, the sheet 92 on which an image is formed is referred to as a printed material 92a.

  The money processing unit 4 includes a deposit unit 4a, a storage unit 4b, and a refund unit 4c. The depositing unit 4a is a mechanism that accepts money supplied by the user into a housing that the user cannot access. Further, the depositing unit 4a determines the deposit amount, which is the amount of the accepted money.

  The storage unit 4b is a mechanism that sorts and stores money by type in the housing. The refund unit 4c includes a change receiving unit 40a and a money discharging unit 40b that can be accessed by the user. The money discharging unit 40b is a mechanism that executes a refund process of discharging a part of the money stored in the storage unit 4b to the change receiving unit 40a under the control of the charging control unit 53. For example, the money discharging unit 40b includes a valve that opens and closes a fall path of money communicating from the storage unit 4b to the change receiving unit 40a, a motor that drives the valve, and the like.

  That is, the money processing unit 4 is a device capable of storing the money received by the depositing unit 4a in the storage unit 4b and further discharging a part of the money stored in the storage unit 4b to the change receiving unit 40a of the refund unit 4c. is there.

  The control unit 5 performs various calculations, data processing, and controls various electric devices included in the image processing apparatus 10. The control unit 5 can exchange data and control signals with the image reading unit 1, the image forming unit 2, the user interface device 3, the money processing unit 4, and the communication unit 6.

  The control unit 5 includes a main control unit 51 that controls various jobs related to image processing, an image processing unit 52 that executes various image processes, and a charging control unit 53 that controls the money processing unit 4. The main control unit 51 further controls the user interface device 3 and the communication unit 6.

  For example, the control unit 5 is realized by a processor such as a CPU (Central Processing Unit) or a DSP (Digital Signal Processor) that executes a program stored in the secondary storage unit 7 or the like.

  The main control unit 51 includes a read control unit 51a, a print control unit 51b, a UI (User Interface) control unit 51c, and the like.

  The reading control unit 51a and the printing control unit 51b cause the image reading unit 1 and the image forming unit 2 to execute the copy job. In the execution of the copy job, the reading control unit 51a causes the image reading unit 1 to execute the reading process, and the print control unit 51b causes the image forming unit 2 to execute the printing process based on the read image.

  The UI control unit 51c inputs information according to an operation on the operation unit 3a, and causes the display unit 3b to display various types of information.

  The image processing unit 52 performs image processing such as processing processing or data conversion processing on the read image data. For example, the image processing unit 52 includes a rasterizing unit 52a that converts the read image data into raster data for printing.

  The charging control unit 53 controls the refund unit 4c to cause the refund unit 4c to execute the change discharge processing. For example, when detecting that the refund button 3x of the operation unit 3a has been operated, the charging control unit 53 causes the refund unit 4c to execute the change discharging process.

  The refund button 3x is an example of a refund operation unit that receives a refund operation. It is also conceivable that the UI control unit 51c causes the display unit 3b to display a refund icon, which is an operation icon corresponding to the refund button 3x. In this case, the refund icon functioning as a part of the operation unit 3a is an example of the refund operation unit.

  By the way, since the image processing apparatus 10 installed in a store or the like is used by an unspecified user, it does not perform user authentication processing. The same applies to conventional devices. Therefore, in the conventional device, when the change that the user has forgotten to collect is collected by a store entrant or the like, the correspondence between the user and the change cannot be confirmed. In this case, the user cannot receive the forgotten change.

  On the other hand, the image processing apparatus 10 executes copy accounting control and post-refund control described later. Thus, if the image processing apparatus 10 is employed, after the user forgets to take the change, the user checks the correspondence between the user and the change that the user has forgotten, and then sends the change to the user. Can be provided.

[Copy accounting control]
Hereinafter, an example of the procedure of the charging control will be described with reference to a flowchart shown in FIG. In the following description, S101, S102,... Represent identification codes of the steps executed in the copy accounting control. The main control unit 51 further includes an ID acquisition unit 51d, a non-acquisition detection unit 51e, and a data management unit 51f to execute the copy accounting control.

  When the UI control unit 51c detects a predetermined copy start operation on the operation unit 3a, the copy charging control is started. The document 91 brought by the user is set on the image reading unit 1 before the copy start operation is performed.

<Step S101>
In the copy accounting control, first, the ID acquisition unit 51d of the main control unit 51 acquires a job ID (D01) that is unique identification information for each copy job from the server device 8.

  In step S101, the ID acquisition unit 51d requests the server device 8 to provide a new job ID (D01), and the server device 8 issues a new job ID (D01) that does not overlap with the previously set job ID (D01). Is set, and the job ID (D01) is transmitted to the image processing apparatus 10.

<Step S102>
Next, the money amount management unit 53a of the charging control unit 53 determines whether the money amount determined by the money reception unit 4a is sufficient.

  Specifically, the money amount management unit 53a calculates a charge amount corresponding to the printing condition specified by the copy start operation, and when the deposit amount is equal to or more than the charge amount, the deposit amount is sufficient. Otherwise, it is determined that the deposit amount is insufficient. The printing condition indicates the content of the printing process.

  For example, the printing condition may include a color condition indicating whether the printing is color printing or monochrome printing, a size condition indicating the size of the sheet 92 to be used, and the like. The amount management unit 53a calculates the charging amount by applying the color condition and the size condition to a predetermined charging formula.

  The amount management unit 53a shifts the processing to step S104 when it is determined that the deposit amount is sufficient, and shifts the processing to step S103 when it is determined that the deposit amount is insufficient.

<Step S103>
When it is determined that the deposit amount is insufficient, the UI control unit 51c causes the display unit 3b to display a message of a deposit guide. The payment guide message is a message that prompts the user to supply money, which is equal to or more than the insufficient amount, to the payment unit 4a.

  After the processing in step S103, the UI control unit 51c shifts the processing to step S102. Thereby, the processing from step S102 is executed again.

<Step S104>
When it is determined that the deposit amount is sufficient, the reading control unit 51a causes the image reading unit 1 to execute the reading process. Thereby, the image of the document 91 brought by the user is read by the image reading unit 1. That is, the image reading unit 1 outputs the read image data representing the image of the document 91.

<Step S105>
Next, the watermark processing unit 52b of the image processing unit 52 adds a non-visibility watermark representing a job ID (D01) to the read image represented by the read image data obtained in step S104.

  That is, the watermark processing unit 52b processes the read image data into data in which the watermark is embedded, and outputs the processed read image data. For example, it is conceivable that the watermark is one or both of a tint block watermark and a font watermark.

<Step S106>
Next, the print control unit 51b causes the image forming unit 2 to execute the printing process based on the read image data in which the watermark data is embedded. Accordingly, the image forming unit 2 forms the read image to which the watermark has been added on the sheet 92.

<Step S107>
Next, the money amount management unit 53a calculates a remaining money amount, which is a difference between the received money amount and the billing amount according to the content of the printing process. At this time, the UI control unit 51c causes the display unit 3b to display information on the calculated remaining amount.

<Step S108>
Next, the UI control unit 51c performs a process of detecting an operation on the operation unit 3a. If the UI control unit 51c detects the copy start operation again, the UI control unit 51c shifts the process to step S102. If the UI control unit 51c detects an operation on the refund button 3x, the UI control unit 51c shifts the process to step S109. Move to

<Step S109>
In step S109, the refund control unit 53b of the charging control unit 53 causes the money discharging unit 40b to execute a primary refund process. The primary refund process is a process of discharging a change corresponding to the remaining amount calculated in step S107 to the change receiving unit 40a.

<Step S110>
Next, the money amount management unit 53a resets the remaining money amount and ends the copy accounting control. The refund control unit 53b does not cause the money discharging unit 40b to execute the primary refund process in a state where the remaining amount is reset.

<Step S111>
In step S111, when an operation on the operation unit 3a is not detected, the non-acquisition detecting unit 51e of the main control unit 51 executes a process of detecting an unacquired state. The unacquired state is a state in which the change corresponding to the remaining amount has not been acquired by the user from the refund unit 4c.

  In the present embodiment, the non-acquisition detecting unit 51e does not operate the image reading unit 1 and the image forming unit 2 and does not perform an operation on the image processing apparatus 10 after the printing process in step S106 is performed. When the state has continued for a predetermined time, the unacquired state is detected.

  Therefore, the image processing apparatus 10 does not require a special sensor for detecting the unacquired state. The special sensor is, for example, a sensor that detects the change present in the change receiving unit 40a.

  When the unacquired state cannot be detected, the unacquired detection unit 51e shifts the processing to step S108. As a result, the processes after step S108 are repeated. On the other hand, the unacquired detection unit 51e shifts the processing to step S112 when detecting the unacquired state.

<Step S112>
In step S112, the data management unit 51f of the main control unit 51 executes a refund management data registration process. The refund management data registration process is a process of storing the refund management data D0 in the data storage unit 8a provided in the server device 8.

  In step S112, the data management unit 51f transmits a registration request including the refund management data D0 to the server device 8. The server device 8 receives the refund management data D0 from the image processing device 10, and stores the received refund management data D0 in the data storage unit 8a as a part of the refund management database D00 (see FIG. 4).

  The refund management data D0 includes the job ID (D01) obtained in step S101 and refund data D02 representing the remaining amount. The job ID (D01) included in the refund management data D0 is an example of refund identification data representing identification information corresponding to the change in which the unacquired state has been detected.

  As will be described later, the data management unit 51f transmits the download request including the information designating the job ID (D01) to the server device 8 to store the refund data D02 corresponding to the job ID (D01). It can be obtained from the storage unit 8a (see step S205 in FIG. 3).

  After executing the process of step S112, the data management unit 51f shifts the process to step S110. Thus, after the process of step S110 is performed, the copy accounting control ends.

  As described above, before the non-acquired state is detected in step S111, the refund control unit 53b sends the primary refund processing to the money processing unit 4 in steps S108 to S109 in response to an operation on the refund button 3x. Is executed. In other words, after the unacquired state is detected in step S111, the refund control unit 53b prohibits the primary refund process.

  If the user forgets to take the change and the unacquired state is detected in step S111, the remaining amount is reset in step S110. Therefore, even if the refund button 3x is operated after the unacquired state is detected, the change is not discharged to the change receiving unit 40a. This prevents another person from taking away the change.

  Further, the image processing apparatus 10 generates the printed matter 92a in which the watermark is embedded by the process of step S106. The refund management data D0 includes a job ID (D01) corresponding to the watermark embedded in the printed matter 92a, and refund data D02 representing the change amount. Accordingly, the refund management data D0 is data representing the correspondence between the printed matter 92a belonging to the user and the change that the user has forgotten.

  The user who forgot to take the change brings the printed matter 92a in which the watermark is embedded, goes to the nearest installation location of the image processing apparatus 10, and operates the image processing apparatus 10, so that the image processing apparatus 10 Execute post-article refund control. Thereby, the change is provided to the user.

[Ex-post refund control]
Hereinafter, an example of the procedure of the post-refund control will be described with reference to the flowchart shown in FIG. In the following description, S201, S202,... Represent identification codes of steps executed in the post-refund control. The image processing unit 52 further includes a watermark extracting unit 52c for executing the post-refund control.

  When the UI control unit 51c detects a predetermined refund mode selection operation on the operation unit 3a and further detects the copy start operation, the post-refund control is started. The refund mode selection operation is an operation for selecting the refund mode as the operation mode. The refund mode is an operation mode for executing the post refund control.

<Step S201>
In the post-refund control, first, the UI control unit 51c causes the display unit 3b to display a message for document set guidance. The document setting guide message prompts the user to set the printed material 92a obtained by the copy job when the change is forgotten as the document 91 in the image reading unit 1.

<Step S202>
Next, the UI control unit 51c performs a process of detecting an operation on the operation unit 3a. When the UI control unit 51c detects the copy start operation, the UI control unit 51c ends the post-refund control, and otherwise continues the process of step S202.

<Step S203>
In step S203, the reading control unit 51a causes the image reading unit 1 to execute the reading process. Thus, the image of the printed matter 92a brought by the user is read by the image reading unit 1. That is, the image reading unit 1 outputs the read image data representing the image of the printed matter 92a brought by the user.

<Step S204>
Next, the watermark extraction unit 52c of the image processing unit 52 performs a watermark extraction process. The watermark extraction process is a process of extracting the watermark from the read image read from the printed matter 92a by the image reading unit 1 in step S203.

  Further, when the watermark can be extracted from the read image, the watermark extracting unit 52c determines whether or not the information represented by the extracted watermark is information representing a job ID (D01). In the following description, information represented by the watermark extracted in step S204 is referred to as extracted watermark information.

  When determining that the extracted watermark information is the information indicating the job ID (D01), the watermark extracting unit 52c shifts the processing to step S205, and otherwise shifts the processing to step S208. Here, the other cases include a case where the extracted watermark information is not information indicating a job ID (D01) and a case where the watermark cannot be extracted from the read image.

<Step S205>
Next, the data management unit 51f executes a refund amount acquisition process. The refund acquisition process is a process of acquiring refund data D02 corresponding to the job ID (D01) represented by the watermark extracted in step S204 from the data storage unit 8a of the server device 8.

  Specifically, in step S205, the data management unit 51f transmits a refund request including the job ID (D01) to the server device 8, and acquires the refund data D02 returned from the server device 8. .

  However, if the refund management database D00 stored in the data storage unit 8a does not include the job ID (D01) included in the refund request, the data management unit 51f cannot acquire the refund data D02.

  In step S205, the data management unit 51f shifts the processing to step S206 when the refund amount data D02 corresponding to the job ID (D01) can be obtained, and shifts the processing to step S208 otherwise.

<Step S206>
In step S206, the refund control unit 53b causes the money discharging unit 40b to execute a secondary refund process. The secondary refund process is a process of discharging the change of the amount represented by the refund amount data D02 obtained in step S205 to the change receiving unit 40a.

<Step S207>
Further, the data management unit 51f executes a process of deleting the refund management data D0 including the job ID (D01) represented by the watermark extracted in the process of step S204 from the data storage unit 8a. Thereafter, the secondary refund process corresponding to the job ID (D01) deleted from the data storage unit 8a cannot be executed.

  Specifically, in step S209, the data management unit 51f transmits a deletion request including the job ID (D01) to the server device 8. The job ID (D01) included in the deletion request is the job ID (D01) represented by the watermark extracted in step S204.

  When receiving the deletion request, the server device 8 deletes the refund management data D0 including the job ID (D01) included in the received deletion request from the refund management database D00 of the data storage unit 8a. That is, the data management unit 51f deletes the refund management data D0 in the data storage unit 8a through the server device 8.

  The processing of steps S206 and S207 is executed when the watermark representing the job ID (D01) in the refund management data D0 stored in the data storage unit 8a is extracted by the watermark extraction processing (step S204). After the end of the process in step S207, the data management unit 51f ends the post-refund control.

<Step S208>
On the other hand, in step S208, the UI control unit 51c causes the display unit 3b to display a predetermined error message. Then, the UI control unit 51c ends the post-refund control.

  The process in step S208 is executed when the watermark is not extracted from the read image in step S204, or when the refund data D02 corresponding to the job ID (D01) is not obtained in step S205.

  As described above, the image processing apparatus 10 confirms the correspondence between the user and the change that the user has forgotten by executing the processing of steps S203 to S206, and then transfers the change to the user. Can be provided.

  The data management unit 51f accesses the server device 8 through the communication unit 6 to store the refund management data D0 in the data storage unit 8a of the server device 8 (S112 in FIG. 2). The process of acquiring the refund data D02 (S205 of FIG. 3) and the process of deleting the refund management data D0 from the data storage unit 8a (S207 of FIG. 3) are executed.

  Therefore, the user who has forgotten to collect the change can obtain the change using the image processing apparatus 10 installed nearest without returning to the installation location of the image processing apparatus 10 used for outputting the printed matter 92a. it can.

[Second embodiment]
Next, an image processing apparatus 10x according to the second embodiment will be described with reference to FIG. In FIG. 5, the same components as those shown in FIG. 1 are denoted by the same reference numerals. Hereinafter, differences between the image processing apparatus 10x and the image processing apparatus 10 will be described.

  The image processing device 10x has a configuration in which a change sensor 700 of the money processing unit 4 and an alarm processing unit 51g of the main control unit 51 are added to the image processing device 10 illustrated in FIG. Further, the user interface device 3 of the image processing device 10x includes a sound output device 3c.

  The change sensor 700 is a sensor that detects the change present in the change receiving unit 40a of the refund unit 4c. For example, the change sensor 700 may be a weight sensor that detects the weight of an object present in the change receiving unit 40a.

  Further, it is conceivable that the change sensor 700 includes a camera for photographing an object present in the change receiving unit 40a and a money detection processing unit for executing image processing. In this case, the money processing unit determines whether an image captured by the camera includes a money image.

  In the present embodiment, the unacquired detection unit 51e can detect the unacquired state after the primary refund process (Step S109 in FIG. 2) is executed. In this case, the unacquired detection unit 51e detects the unacquired state when the state in which the change of the change receiving unit 40a is detected by the change sensor 700 continues for a predetermined time.

  The alarm processing unit 51g executes an alarm process when the unacquired state is detected by the unacquired detection unit 51e. For example, it is conceivable that the warning process is a process of outputting a warning sound through the sound output device 3c and outputting a message prompting the collection of the change to the display unit 3b.

  An administrator of the image processing apparatus 10 in a store or the like collects the change that the user has forgotten in response to the alarm processing. This prevents another person from taking away the change that has been discharged to the change receiving portion 40a. When the warning process is performed, the process of step S112 in FIG. 2 may also be performed.

  When the image processing device 10x is employed, the same effect as when the image processing device 10 is employed is obtained.

[Application example]
In the image processing devices 10 and 10x described above, the data management unit 51f may store the refund management data D0 in the secondary storage unit 7 of the own device.

  In this application example, the data management unit 51f causes the secondary storage unit 7 to store the refund management data D0 in step S112 of FIG. Further, the data management unit 51f acquires the refund data D02 corresponding to the job ID (D01) from the secondary storage unit 7 in step S205 in FIG. Further, the data management unit 51f deletes the refund management data D0 from the secondary storage unit 7 in step S207 of FIG.

  In the application example, the main control unit 51 includes an ID setting unit instead of the ID acquisition unit 51e. The ID setting unit sets a new job ID (D01) that does not overlap with the previously set job ID (D01) in step S101 of FIG.

  However, in this application example, the user needs to return to the installation location of the image processing apparatus 10 used for outputting the printed matter 92a in order to obtain the change that has been forgotten. In this application example, the secondary storage unit 7 is an example of a nonvolatile data storage unit.
