For convenience of explanation, it is assumed that the digital multi-function peripheral according to the first embodiment has three cases as the operation state of the device main body 1; the first operation state, the second operation state, and the third operation state.

  The first operation status is a status where the device main body 1 is not executing any job relating to the copy, print, or facsimile functions, or a status where the device main body is waiting without receiving any instruction from the user. It is.

  The second operation status refers to a status in which the apparatus main body 1 is performing various operations in order to execute jobs relating to copy, print, and facsimile functions. More specifically, in the copy function, operations relating to reading of a document, taking of a recording sheet, formation of an image based on the image data, discharge of a recording sheet after image formation, and the like are being performed. In the printing function, reception of image data to be printed from an external device, reading of already stored image data, loading of recording paper, formation of an image based on the image data, discharge of recording paper after image formation, etc. This is a situation where the operation related to is performed. Further, in the facsimile function, reading of a document, transmission of read image data, reception of image data to be printed from an external device, taking of recording paper, formation of an image based on the image data, recording paper after image formation This is a situation where operations related to the discharge of wastewater are performed.

  The third operation status is an abnormal situation in which the job relating to the received instruction cannot be normally completed due to occurrence of paper, that is, out of paper, lack of toner, communication interruption with the outside, and the like. That is, the first operation state and the second operation state are operation states when the device main body is normal, and the third operation state is an operation state when the device main body is abnormal.

  When power is supplied to the digital multifunction peripheral according to the first embodiment, the operation status of the device body 1 is the first operation status, and as described above, the plurality of soft keys 5B related to some jobs and the current status Text for notifying the user that the user is waiting, for example, “Copy can be read.” Is displayed on the display unit 5. Thereafter, the user receives an instruction from the user by operating the hard key or the soft key, and the apparatus main body 1 performs various operations in order to execute a job related to the received instruction. It becomes. If an abnormality such as paper out, paper out, toner shortage, or the like occurs before or during the execution of the job, the device main body 1 enters the third operation state. On the other hand, when the execution of the job according to the user's instruction is completed without any abnormality, or when the abnormality that has occurred is resolved, the device main body 1 enters the first operation state again. That is, when the digital multi-function peripheral is in a power-on state, the operation status of the device main body 1 is in one of the first operation status, the second operation status, and the third operation status. Hereinafter, a case where the receiving unit 7 is removed from the device body 1 while the operation state of the device body 1 is any one of the first operation state, the second operation state, and the third operation state will be described as an example. . Before the reception unit 7 is removed from the device main body 1, the connection terminal 3a and the connection terminal 3b are interconnected, and the reception unit 7 and the device main body 1 perform wired communication.

  The CPU 101 determines whether or not the receiving unit 7 has been removed from the device main body 1 (S101). This determination is performed by monitoring the continuity between the connection terminal 3a and the connection terminal 3b. That is, when continuity between the connection terminal 3a and the connection terminal 3b is detected, the CPU 101 determines that the receiving unit 7 is not detached from the device body 1, and there is no continuity between the connection terminal 3a and the connection terminal 3b. Is detected, it is determined that the receiving unit 7 has been removed from the device main body 1.

  When the CPU 101 determines that the reception unit 7 is not detached from the device main body 1 (S101: NO), the CPU 101 repeats the determination until the reception unit 7 is removed from the device main body 1. At this time, the image displayed on the display unit 5 does not change unless, for example, the user operates the hard key or the soft key. On the other hand, when the CPU 101 determines that the receiving unit 7 has been removed from the device main body 1 (S101: YES), the CPU 101 performs wireless communication (S102). That is, the CPU 101 instructs the switching unit 62 to perform wireless communication, and the switching unit 62 stops the wired communication via the connection terminal 3 a and the connection terminal 3 b in accordance with the instruction from the CPU 101 and performs wireless communication using the wireless communication unit 2. The wireless communication between the transmission / reception unit of the wireless communication unit 2 and the transmission / reception unit of the reception unit 7 is performed. As described above, when the receiving unit 7 is detached from the device main body 1, it may be configured to switch from wired communication to wireless communication, or may be configured to always perform both wired communication and wireless communication. . In other words, when the reception unit 7 is not detached from the device main body 1, data by wired communication is given priority, and when the reception unit 7 is removed from the device main body 1, data by wireless communication is given priority. Also good.

  Next, the CPU 101 detects the state of each part of the device main body 1 when the receiving unit 7 is removed from the device main body 1 (S103). Using the detection result, the CPU 101 normally executes a job such as copying, printing, and data transmission in the first operation state that is normal but not executing any job (or waiting for an instruction from the user) It is determined whether the second operation state is in the third operation state in which an abnormality such as out of paper, out of paper, or toner shortage has occurred.

  For example, regarding the second operation situation, the document detection sensor 12 determines whether there is a document on the document tray 11, whether the temperature of the heat roller of the fixing unit 27 is equal to or higher than a predetermined temperature, the reading unit 8, and the back reading. Whether or not a predetermined drive voltage is applied to the unit 9 and the process unit or the like is detected. In addition, regarding the first operation status, it is detected whether or not there is a received or reserved job.

  On the other hand, regarding the third operation status, for example, whether or not there is a recording sheet by a sheet replenishment sensor that detects the presence or absence of the recording sheet placed on the manual feed tray 38 or the sheet feeding cassette 30, 51, 52, 53. Whether or not the recording sheet that has passed through the pickup rollers 38a, 51a, 52a, and 53a is discharged within a predetermined time by a discharge detection sensor that detects the discharge of the sheet on which the image is formed is determined from the toner discharge port of the toner cartridge. By monitoring the amount of toner discharged (for example, per unit time), it is detected whether or not the amount of discharged toner is a predetermined value or less. In addition, continuity detecting means for detecting the presence / absence of continuity of the reading unit 8, the back reading unit 9, and the process unit is provided, and the continuity detecting means detects whether there is continuity.

Based on the detection result in S103, the CPU 101 determines whether or not the third operation state in which an abnormality has occurred in the device main body 1 (S104).
For example, based on the detection result of the paper discharge detection sensor, it is determined whether or not the operation state is the third.
Further, based on the detection result of the paper replenishment sensor, it is determined whether or not the operation state is the third.
Further, based on the monitoring of the amount of discharged toner, it is determined whether or not the operation state is the third.

When the CPU 101 determines that the device main body 1 is in the third operation state (S104: YES), the CPU 101 instructs the screen image creation unit 102 to create an image indicating the content and location of the abnormality that has occurred, and the screen image creation unit 102 Creates an image based on the data stored in the image memory 105, and the created image is displayed on the display unit 5 (S105).
When it is determined as the third operation situation, an abnormality has already occurred in the device main body 1 before the reception unit is removed. When an abnormality occurs in the device main body 1, an image indicating the content, location, and soft key 5B (operation guide) of the abnormality that has already occurred on the display unit 5 is displayed before the reception unit is removed. That is, when the device main body 1 is abnormal, the same image is displayed on the display unit 5 before and after the reception unit 7 is removed.

For example, if it is determined that the recording paper has not been discharged within a predetermined time and the third operation status is due to paper clogging, the text “paper clogged” and the paper that clogged the paper have occurred. A soft key 5B (operation guide) for receiving an image indicating the location of the cassette and an instruction to display a detailed processing method for eliminating clogging of the generated paper is displayed on the display unit 5.
If there is no recording paper placed on the manual feed tray 38 or the paper feed cassette 30, 51, 52, 53, and it is determined that the third operation status is due to running out of paper, “out of paper”. And a soft key 5B (operation guide) for receiving an instruction to display a detailed processing method for eliminating the out-of-paper condition and an image showing the location of the paper cassette in which the out-of-paper condition has occurred. Is done.
In addition, when it is determined that the toner discharge amount from the toner discharge port is equal to or less than a predetermined value and the operation state is due to the toner shortage, the text “Toner shortage”, the toner cartridge in which the toner shortage has occurred A soft key 5B (operation guide) is displayed on the display unit 5 for receiving an image indicating the location of the image and an instruction for displaying a detailed processing method for eliminating the generated toner shortage.

  In the following description, an image displayed on the display unit 5 before and after the reception unit 7 is detached from the device main body 1 when the third operation state is determined using paper clogging as an example will be described with reference to FIG. explain in detail. FIG. 8 is an exemplary diagram showing an example of images displayed on the display unit 5 before and after the receiving unit 7 is detached from the device main body 1. On the display unit 5 before the reception unit 7 is removed from the device body 1, the text “paper clogged” notifying that paper clogging has occurred, the arrow indicating the clogging location of the paper, and the paper In other words, a soft key 5B (operation guide) for receiving an instruction to display a detailed processing method for solving the problem is displayed as a pop-up window. Also, the display unit 5 after the reception unit 7 is detached from the device main body 1 is notified of the occurrence of paper clogging, which is the same as before the reception unit 7 is removed from the device main body 1. The soft key 5B (operation guide) for accepting an instruction for displaying a detailed processing method for eliminating the clogging of the paper, the arrow indicating the location where the paper is clogged, and the paper is displayed as a pop-up window. That is, the same image is displayed before and after the reception unit is detached. The user removes the receiving unit 7 and moves to the place where the paper clogging occurs while confirming the display contents of the image of the same paper clogging place before and after the removal.

  The CPU 101 determines whether or not the soft key 5B (operation guide) has been operated (S110). This determination is performed by monitoring the pressing of the soft key 5B (operation guide). When the CPU 101 determines that the soft key 5B (operation guide) has been operated (S110: YES), the CPU 101 instructs the screen image creation unit 102 to create an image indicating a detailed processing method for eliminating the abnormality that has occurred. Based on the data stored in the image memory 105, the screen image creation unit 102 creates an image indicating a detailed processing method for eliminating the abnormality that has occurred. The generated image showing the detailed processing method for eliminating the abnormality is switched to an image showing the content and location of the abnormality displayed when the reception unit is removed and displayed on the display unit 5 (S111). When it is determined that the soft key 5B (operation guide) is not operated (S110: NO), an image indicating the content and location of the abnormality that has occurred is continuously displayed.

  Taking the clogging of paper as an example, an image displayed after the operation of the soft key 5B (operation guide) will be described in detail with reference to FIG. FIG. 9 is an exemplary diagram illustrating an example of an image displayed on the display unit 5 when the “operation guide” is operated after the reception unit 7 is detached from the device main body 1. The image of FIG. 8 is displayed before the soft key 5B (operation guide) is operated after the reception unit 7 is removed from the device main body 1 when it is determined as the third operation state. After the soft key 5B (operation guide) is operated, the text relating to the detailed processing method for eliminating the clogging of the paper “Open the front cover of the finisher.” And the explanatory diagram for supplementing the text are displayed. . A user who has moved to a place where the paper has been clogged while confirming the display contents of the image before operating the soft key 5B (operation guide), operates the soft key 5B (operation guide) and removes the reception unit. The paper clogging is eliminated while confirming the details of the detailed processing method for eliminating the clogging of the generated paper displayed on the display unit.

  On the other hand, when the CPU 101 determines that the device main body 1 is normal rather than the third operation status (S104: NO), the CPU 101 determines whether or not the device main body 1 is in the second operation status (S106). When the CPU 101 determines that the device main body 1 is in the second operation state in which the operation is performed to execute the job (S106: YES), the CPU 101 instructs the screen image creation unit 102 to create a job processing state image. The screen image creation unit 102 creates a job processing status image indicating the processing status of the job based on the data stored in the image memory 103, and the created processing status image of the job is displayed on the display unit 5. It is displayed (S107). That is, before the reception unit 7 is removed from the device main body 1, the operation status of the device main body 1 is in the process of executing a job such as copying, printing, data transmission, and any job is currently being executed. A text notifying the user of the fact is displayed. Thereafter, when the receiving unit 7 is removed from the device main body 1, information such as the contents of the job currently being executed, the processing rate of the job, a list of jobs to be executed next, and the like are displayed on the display unit 5.

  Hereinafter, the image change of the display part 5 before and after the reception part 7 is removed from the apparatus main body 1 in a 2nd operation | movement condition is demonstrated in detail using FIG.10 and FIG.11. FIG. 10 is an exemplary view showing an example of an image displayed on the display unit 5 before the reception unit 7 is detached from the device main body 1. FIG. 11 shows an example of the image displayed on the display unit 5 after the reception unit 7 is removed from the device main body 1. It is an illustration figure which shows an example of the image to display. In the display unit 5 before the reception unit 7 is removed from the device main body 1, the text “Copying. Copy reservation is possible.” Is displayed to notify that a copy job is currently being executed. . On the other hand, unlike the image before being removed, the display unit 5 after the receiving unit 7 is removed from the device main body 1 indicates that the job currently being executed is printing, the processing rate of the printing, and the next A list indicating that jobs such as data transmission and copying are performed in order is displayed. Originally, this image is an image displayed on the display unit 5 by operating the “job status” of the hard key provided on the operation unit 6 of the receiving unit 7. The operation of the hard key can be omitted for the convenience of the user. For example, when the user makes a copy and the amount of originals to be copied is large, the reception unit 7 is removed after the copy is started, and the user returns to the seat with the removed reception unit 7 and the job ( While checking the processing status of (Copy), another work can be performed by the end of the copy.

  On the other hand, when the CPU 101 determines that the device main body 1 is not in the second operation state (S106: NO), the CPU 101 determines whether or not the device main body 1 is in the first operation state (S108). When the CPU 101 determines that the device main body 1 is not executing any job, or has received no instruction from the user and is in the first operation state in which the device main body is on standby (S108: YES), the display The screen image creation unit 102 is instructed to create an image having a different character size to be displayed on the unit 5 (enlarged or reduced before being removed), and the screen image creation unit 102 stores the data stored in the image memory 105. Based on this, images with different sizes of characters to be displayed are created, and the created images are displayed on the display unit 5 (S109). That is, before the reception unit 7 is removed from the device main body 1, the device main body 1 is not executing any job related to the copy, print, and facsimile functions, and notifies the user that the user instruction can be received. The text to be displayed is displayed on the display unit 5. Thereafter, when the receiving unit 7 is removed from the device main body 1, an image enlarged or reduced from the size before the character is removed is displayed on the display unit 5, unlike the image before being removed. That is, when the apparatus main body 1 is in the first operation state and the reception unit 7 is removed from the apparatus main body 1, the user is a physically handicapped person or an elderly person who uses a wheelchair. Can be assumed that the reception unit 7 has been removed because it is higher than the line of sight and the display content of the display unit 5 cannot be confirmed. To cope with this, for example, important information of characters to be displayed The display unit 5 displays an image of a so-called universal design, such as displaying the characters relating to the information in a greatly enlarged manner and displaying the characters relating to the additional information in a reduced size.

  Moreover, before the size of the character to be displayed is increased or decreased in preparation for the case where the user who has removed the receiving unit 7 from the device main body 1 when the device main body 1 is in the first operation state is a healthy person who has no obstacles. The soft key 5B for returning to the image may be displayed as a pop-up window.

  In S109, the case where an image in which the size of the character to be displayed is enlarged or reduced is displayed on the display unit 5 is described as an example. However, the present invention is not limited to this. Any image that enhances the visibility of a free person, an intellectually disabled person, an elderly person, or the like may be used.

  On the other hand, when the CPU 101 determines that the device main body 1 is not in the first operation status (S108: NO), the CPU 101 moves to the processing of S107 and displays a job processing status image for displaying the job processing status on the display unit 5. .

  In the first embodiment described above, the case where the processing status of the job is displayed on the display unit 5 when the receiving unit 7 is removed when the device main body 1 is in the second operation status has been described as an example. However, it is not limited to this. For example, when the receiving unit 7 is removed within a predetermined time after the device main body 1 starts any operation (job) after the device main body 1 starts any operation (job), the processing status image of the job is shown on the display unit 5. When the reception unit 7 is removed after a predetermined time, an image in which the size of characters to be displayed is increased or decreased may be displayed on the display unit 5.

  In the digital multi-functional peripheral as described above, when the reception unit 7 is removed when the device main body 1 is normal, an image different from that before the reception unit 7 is removed is displayed on the display unit 5. The image when the reception unit 7 is removed is an image according to the operation status of the device main body 1 when the reception unit 7 is removed, and an image expected to be used by the user after the reception unit 7 is removed. By displaying according to a plurality of situations without the user performing display switching operation, the convenience of the user can be achieved. Further, when the reception unit 7 is removed from the device main body 1 when the device main body 1 is abnormal, the same image as that before the reception unit 7 is removed is displayed on the display unit 5. The image when the reception unit 7 is removed is an image showing the content and location of the abnormality that has occurred and expected to be used by the user after the reception unit 7 is removed, and is the same image as before the removal of the reception unit 7 is there. The user can move to a place where an abnormality has occurred while checking the display contents displayed on the display unit of the removed reception unit at hand without performing a display switching operation. After moving to the place where the abnormality occurred, operate the soft key 5B (operation guide) to display the screen showing the operation procedure necessary for recovery of each abnormality, and recover the abnormality while checking the display contents at hand This makes it possible to perform operations necessary for the digital multi-function peripheral.

(Embodiment 2)
FIG. 12 is a perspective view of the digital multi-function peripheral according to Embodiment 2 of the present invention in a state where the display unit 5 is detached from the device main body 1, and FIG. 13 is a perspective view of the digital multi-function peripheral according to Embodiment 2 of the present invention. It is a block diagram which shows the principal part structure. In the digital multi-function peripheral according to Embodiment 2 of the present invention, only the display unit 5 of the receiving unit 7 is detachably attached. When the display unit 5 is attached to the device main body 1, wired communication is performed with the device main body 1, and when the display unit 5 is detached from the device main body 1, wireless communication with the device main body 1 is performed. Wired communication between the display unit 5 and the device body 1 is performed via a pair of connection terminals 3c and 3d. A connection terminal 3d for performing serial communication (wired communication) with the device main body 1 is provided on the rear surface of the display unit 5, and the display unit 5 and serial communication are provided at positions corresponding to the connection terminal 3d of the device main body 1. A connection terminal 3c on the device main body 1 side for performing the above is provided. The display unit 5 includes a transceiver (not shown). When the display unit 5 is detached from the device main body 1, the display unit 5 communicates with the device main body 1 using the transceiver.

  The wireless communication unit 2 includes a transceiver (not shown) having an IP address, an ID, and the like so that 1: 1 wireless communication with the transceiver on the display unit 5 side is possible. When detached from the main body 1, wireless communication is performed with the transceiver on the display unit 5 side using the transceiver.

  FIG. 14 is a flowchart showing a processing procedure performed by the CPU 101 of the digital multi-function peripheral according to Embodiment 2 of the present invention. For convenience of explanation, it is assumed that the digital multifunction peripheral according to the second embodiment has three cases as the operation state of the device main body 1, the first operation state, the second operation state, and the third operation state. In the following description, a case where paper clogging occurs as the third operation situation will be described as an example.

  When the user operates the power key of the reception unit 7, the power of the digital multifunction peripheral according to the second embodiment is turned on. After that, the operation status of the device main body 1 is normal, but no job is executed (or waiting for an instruction from the user), the first operation status, copying, printing, data transmission, etc. are executed normally This corresponds to one of the second operating status and the third operating status in which an abnormality such as out of paper, that is, out of paper or toner shortage has occurred. At this time, the display unit 5 is not detached from the device main body 1, and the connection terminal 3 c and the connection terminal 3 d are connected to each other, and performs wired communication with the device main body 1.

  The CPU 101 determines whether or not the display unit 5 has been removed from the device main body 1 (S201). The determination is performed by the CPU 101 monitoring the continuity between the connection terminal 3c and the connection terminal 3d.

  When it is determined that the display unit 5 is not detached from the device main body 1 (S201: NO), the CPU 101 repeats the determination until the display unit 5 is detached from the device main body 1. On the other hand, when the CPU 101 determines that the display unit 5 has been removed from the device main body 1 (S201: YES), the CPU 101 performs wireless communication (S202).

  Next, the CPU 101 detects the status of each part of the device main body 1 at the time when the display unit 5 is detached from the device main body 1 (S203). For example, the CPU 101 determines whether or not there is a document on the document tray 11, the temperature of the heat roller of the fixing unit 27, the drive voltage of the reading unit 8, the presence or absence of an accepted job, the presence or absence of recording paper, the presence or absence of paper discharge, and the discharge of toner. The amount, the presence / absence of conduction of the reading unit 8 and the like are detected.

Based on the detection result in S203, the CPU 101 determines whether or not the third operation state in which an abnormality has occurred in the device main body 1 (S204). When the CPU 101 determines that the device main body 1 is in the third operation state (S204: YES), the soft key 5B (for receiving an instruction to display details of the abnormality that has occurred, the location, and a detailed processing method for eliminating the abnormality) ( An image indicating an operation guide is displayed on the display unit 5 (S205).
When it is determined as the third operation state, an abnormality has already occurred in the device main body 1 before the reception unit is removed. When an abnormality occurs in the device main body 1, an image indicating the content, location, and soft key 5B (operation guide) of the abnormality that has already occurred on the display unit 5 is displayed before the reception unit is removed. That is, when the device main body 1 is abnormal, the same image is displayed on the display unit 5 before and after the reception unit 7 is removed.

  The CPU 101 determines whether or not the soft key 5B (operation guide) has been operated (S210). When the CPU 101 determines that the soft key 5B (operation guide) has been operated (S210: YES), the CPU 101 displays an image indicating a detailed processing method for eliminating the generated abnormality on the display unit 5 (S211). When it is determined that the soft key 5B (operation guide) has not been operated (S210: NO), an image indicating the content of the abnormality that has occurred and the location of the abnormality is continuously displayed.

  On the other hand, when the CPU 101 determines that the device main body 1 is normal rather than the third operation status (S204: NO), the CPU 101 determines whether the device main body 1 is in the second operation status (S206). When the CPU 101 determines that the device main body 1 is in the second operation state (S206: YES), the job processing for displaying the processing status of the job such as the number of read originals, the number of printed originals, the data transmission rate, etc. The situation image is displayed on the display unit 5 (S207).

  On the other hand, when the CPU 101 determines that the device main body 1 is not in the second operation state (S206: NO), the CPU 101 determines whether or not the device main body 1 is in the first operation state (S208). When the CPU 101 determines that the device main body 1 is in the first operation state (S208: YES), the number or area of the soft keys 5B on the touch panel 5A is different (for example, the area is enlarged, the number is reduced, etc.). 5 is displayed (S209). Specifically, before the receiving unit 7 is removed from the device main body 1, the device main body 1 has not executed any job relating to the copy, print, and facsimile functions, and can accept the user's instruction. The text to be notified is displayed on the display unit 5. Thereafter, when the receiving unit 7 is detached from the device main body 1, an image in which the area of the soft key 5 </ b> B is increased or decreased before the receiving unit 7 is removed from the device main body 1 is displayed on the display unit 5.

  Hereinafter, the image change of the display part 5 before and after the reception part 7 is removed from the apparatus main body 1 in a 1st operation | movement condition is demonstrated in detail using FIG.15 and FIG.16. FIG. 15 is an exemplary diagram showing an example of an image displayed on the display unit 5 before the display unit 5 is detached from the device main body 1, and FIG. 16 shows the display unit 5 after the display unit 5 is detached from the device main body 1. It is an illustration figure which shows an example of the image displayed on. In the display unit 5 before the display unit 5 is detached from the device body 1, the text “Copy can be read” is displayed, no job is executed, and an instruction from the user can be accepted. Notifying that it can be done. On the other hand, in the display unit 5 after the display unit 5 is detached from the device main body 1, the number of soft keys 5B is reduced compared with that before the display unit 5 is removed, and only the soft keys 5B related to the basic job or important functions have a large area. And an image of a so-called universal design displayed using enlarged characters is displayed. In S209, the case where an image in which the area of the soft key 5B is enlarged is displayed on the display unit 5 is described as an example. However, the present invention is not limited to this. The soft keys 5B related to functions or important functions may be displayed with an enlarged area, and the soft keys 5B related to additional functions that are not frequently used may be displayed with a reduced area.

  On the other hand, when the CPU 101 determines that the device main body 1 is not in the first operation status (S208: NO), the CPU 101 moves to the processing of S207 and displays a job processing status image for displaying the job processing status on the display unit 5. .

  Similar to the first embodiment, corresponding parts are denoted by the same reference numerals, and detailed description thereof is omitted.
