  However, in the above-described prior art, when a jam processing occurs, the processing procedure and the portion to be operated as shown in FIG. 3 are displayed, but when the user actually operates, it is not necessarily the same as the portion intended to repair the jam. The location is not always manipulated.

  In particular, when there are a plurality of parts that can be operated, it is difficult for the user to know which part can be operated, and there is a possibility that a part different from the part intended to repair the jam may be operated.

  In view of the above-described problems, the present invention displays the location where the user has operated in error on the screen displaying the location where the user actually wants to operate, thereby actually operating the location operated by himself / herself. The purpose is to make it easier to understand where you have to.

  The present invention is premised on an image forming apparatus including a jam detection unit that detects a jam state in a plurality of paper passage portions and a jam processing image storage unit that stores a jam processing procedure.

  An image forming apparatus according to the present invention includes an operation position detection unit that detects a position at which a user operates to perform jam processing, and an operation position storage unit that stores the operation position, and the jam processing procedure is displayed. In addition, the index image is displayed so as to overlap the operation position.

  As a result, the position at which the user is operating for jam processing can be detected, and the jam processing display means can display the index image superimposed on the operation position obtained from the operation section position storage means.

  Therefore, the part operated by the user can be shown on the screen displaying the jam processing procedure, and the user can easily grasp whether or not the current operation is wrong. Furthermore, since the places that must actually be operated can be compared on the same screen, it becomes easier to grasp the places that must actually be operated.

  According to the present invention, it is easy for the user to grasp that the current operation is wrong by indicating the location where the user has made an erroneous operation on the screen displaying the jam processing procedure. In addition, since it is possible to compare the part that has been operated and the part that must be actually operated on the same screen, it is easier to grasp the part that must be actually operated.

  Hereinafter, a case where the present invention is applied to a copying machine as an image forming apparatus will be described as an example.

  FIG. 1 is a schematic diagram showing the internal structure of a copying machine according to an embodiment of the present invention, and FIG. 2 is a functional block diagram showing the overall configuration of the copying machine. FIG. 3 is a flowchart showing the operation of the copying machine.

  As shown in FIG. 1, the copying machine includes a fixing knob 7, a conveyance release lever 7a, and a conveyance knob 7b.

  The fixing knob 7 is interlocked with the fixing roller, and is used to take out the jammed paper by rotating it when a jam such as a paper jam occurs on the fixing roller. This is a release lever for enabling the conveyance portion to be pulled out in order to clear the paper jam when a jam such as a paper jam occurs. The transport knob 7b is interlocked with the transport roller, and is used to rotate and take out the jammed paper when a jam such as a paper jam occurs on the transport roller.

  Further, as shown in FIG. 2, a jam detecting means 1 comprising a plurality of jam sensors arranged in the paper transport path of the copying machine is provided. The output of each jam sensor constituting the jam detection means 1 is input to the jam processed image storage means 2. As shown in FIG. 3, the jammed image storage means 2 includes still image information or moving image information depicting a jam processing procedure when a jam occurs at the position of the jam sensor corresponding to each jam sensor. Is stored. This still image information or moving image information usually corresponds to a plurality of sets of still images or moving images depicting the procedure for the above jam processing, and in the case of a still image, the plurality of images are sequentially displayed on the display 4. In the case of a moving image, a plurality of images are sequentially displayed on the display 4 in time series.

  The image information indicating the jam processing procedure output from the jam processing image storage means 2 is converted into dot data, temporarily developed in the image memory 3, and displayed on the display 4.

  With the above configuration, for example, when a jam sensor at a position corresponding to the fixing roller detects a jam, for example, three still images as shown in FIG. 5 are sequentially displayed. 5A is a screen showing a state in which the front cover is opened, FIG. 5B is a screen showing that the fixing knob 7 is rotated, and FIG. 5C is a screen showing a state where the jammed paper is taken out.

  The operation of the copying machine when a jam occurs due to this configuration will be described with reference to FIG.

  When a jam occurs at the position of the fixing roller as shown in FIG. 5B, when the jam sensor at the position detects the jam, the image information of the jam processing procedure 7 is read from the jam processing image storage means shown in FIG. First, the image shown in FIG. 5A is developed on the image memory 3 and displayed on the display 4 (S1 → S2).

  On the other hand, when no jam occurs and no jam is detected, the process proceeds to other processing (S1 → S3).

  Thereafter, in the processing stage of rotating the fixing knob 7 shown in FIG. 5B, the user can repair the jam according to the image showing the jam processing procedure. It may be misidentified as a position and try to deal with jamming.

  Therefore, in the present invention, the operation position detecting means 5 is further provided. That is, when a user moves a part to be operated during jam processing, a sensor provided at the position detects the movement and inputs it to the operation position storage means 6. Of course, the operation part is a plurality of parts that can be operated by the user. Therefore, the operation position detecting means 5 is composed of a plurality of sensors respectively provided in the plurality of parts.

  As shown in FIG. 6, the operation position storage means 6 stores a position on an image depicting the jam processing procedure corresponding to each of the plurality of parts, and index image information to be displayed at the position. ing. Thus, when a signal indicating that the user is operating is input from any of the above sensors, the position information of the corresponding operation part and the index to be displayed at that position, for example, an index finger mark or an image of an arrow Information is input to the image memory 3.

  In the determination process S4, when the part that should be operated is not operated, as shown in FIG. 7, the user applies the image corresponding to the jam processing procedure developed in the image memory 3 as described above. An index image (an index finger mark or an icon such as an arrow) indicating the position of the operated part is displayed in an overlapping manner (S4 → S6). In FIG. 7B1, when the fixing roller is at the actual jam position, the user erroneously recognizes and operates the conveyance release lever 7a, so that the state where the conveyance release lever 7a is indicated by the index finger is displayed. Moreover, in FIG. 7B2, the state which has shown the conveyance knob 7b with the index finger is displayed. In addition, as shown to FIG. 7B3, you may color in the location which shows the position which the user is operating.

  In this way, the location operated by the user can be shown on the screen displaying the jam processing procedure, and the user can easily grasp whether or not the current operation is wrong.

  In addition, since it is possible to compare locations that must actually be operated on the same screen, it is easier to grasp the locations that must actually be operated, and the operability of jam processing is improved.

  On the other hand, when the part that should be operated in the determination process S4 is operated, but the jam processing is not finished, the next processing screen FIG. 5C is displayed (S4 → S5 → S8). When the jam processing is completed, the jam processing screen is deleted (S4 → S5 → S7).

  Note that the configuration described in the above embodiment is merely a specific example, and does not limit the technical scope of the present invention. Any configuration can be employed within the scope of the effects of the present application.

  In the image forming apparatus such as a copying machine according to the present invention, in the jam processing when a jam occurs, a place where the user has operated and a place where the user actually has to operate can be compared on the same screen. This makes it easier to grasp the points that must be done.
