Description

  The present invention relates to an operation guidance display device including an object display unit that displays a generated video object on a screen.

  Conventionally, when a paper jam occurs in an image forming apparatus such as a multifunction peripheral or a printer, the image forming apparatus stops, and the user needs to remove the paper jammed in the paper passing path of the image forming apparatus. Means for displaying the position and processing method of a paper jam on the display of the image forming apparatus has been proposed. However, even if the user performs an operation to remove the paper according to the display, the paper remains in the jammed paper or the paper passing path. The above display method has a problem that it is difficult for general users to find out how to remove a sheet from a place where the sheet is jammed or where the sheet stays.

  Therefore, in Patent Document 1, a door opening / closing detection device for detecting the opening / closing of a door is arranged inside the copying machine casing, and a translucent decal for explaining a jam processing method is pasted on the inner side surface of the door. When a jam is detected by the jam detection / jam position detection device, the lighting device and LED provided on the door on the back of the decal are lit, the jam position in the decal and the jam processing method display are illuminated, and the operator is required. An image forming apparatus capable of easily recognizing a work location has been proposed.

  Further, in Patent Document 2, in order to grasp the position of the detachable operation unit and the operation unit, the position information receiving device installed at a necessary location and the position information from the position information receiving device are received and the position of the operation unit is determined. Determination means for displaying, information for displaying information corresponding to the position of the operation unit on the operation unit device, a processing device for determining the status of manual operation of the device, and determining operation unit position information There has been proposed a print processing apparatus characterized by having a display means for performing a corresponding display process and a determination means for determining the status of manual operation.

  However, in the image forming apparatus described in Patent Document 1 described above, the amount of information that can be displayed is limited, and in recent years, in multifunctional multifunctional machines, there are many places where paper jams may occur. There is a problem that the processing method is difficult to understand because the amount of information that can be displayed is small. Further, in the print processing apparatus described in Patent Document 2 described above, since the entire processing apparatus is displayed on the display unit, a display having a size capable of sufficiently grasping the position where the paper is jammed is necessary. There has been a problem that the size of the print processing apparatus itself becomes very large.

  Furthermore, even if the user can remove the paper where the paper jam has occurred, the paper remains when other paper remains in the paper path and the error is not cleared even after the paper jam is cleared. There is also a problem that the error cannot be canceled because the existing paper cannot be easily found. Further, if the image forming apparatus recovers with the paper remaining in the paper passing path, further paper jam occurs at the place where the paper remains, which damages the internal equipment of the image forming apparatus. There was also a risk of it.
