Description of the Related Art In recent years, it has been possible to use a scanner or printer of a digital copying machine for facsimile communication, or use a printer of a digital copying machine to expand code data from a computer into bitmap data and print it out. Complex machines have been put to practical use.

Further, such a combination can be realized by, for example, a copying function, a facsimile function, a printer formatter function,
Three or more functions such as an image electronic file function and an image memory function are configured as one unit, and functional processing is being enhanced to further increase the added value.

In the composite image input / output device configured as described above, the scanner and the printer owned by the respective functions are shared to save space and reduce cost.

Further, in such a composite image input / output device, when a paper jam (paper jam) or the like occurs in the printer unit or the reader unit, an LED display on the operation panel lights up at the place where the paper jam occurs. Or the entire display area of the operation panel is used for display.

However, when operating the operation screen of either the copy function, the facsimile function or the printer function, a plurality of functions different from the operation screen are displayed while the reader unit or the printer unit is being used. When a paper jam occurs at a location, the LED display on the operation panel or the paper jam display on the entire surface could not determine which function caused the paper jam.

For example, in the case of LED display, when the printer operation is being performed and when the received document is output on the operation screen of the facsimile, it is easy to establish the causal relationship why the printer unit is causing a paper jam. There was a problem such as not being able to grasp.

The present invention has been made in order to solve the above-mentioned problems, and compares a function factor of a paper jam occurring due to execution of each functional process with a current functional process execution state on the operation unit.

It is configured to display the entire display screen.

Further, when the control means determines that the function processing during the operation instruction on the operation panel means is different from the function processing during the operation resulting in the conveyance jam, the display section of the operation panel means is jammed with paper. It is configured to display a part of the display screen.

Further, the control means is configured to switch the paper jam display screen that is entirely displayed on the display unit of the operation panel means to a reduced paper jam screen display that has been reduced after a certain period of time.

Further, the control means is configured such that after a certain period of time, the paper jam display screen partially displayed on the display portion of the operation panel means is switched to an enlarged paper jam screen display.

Further, when the control means determines that the function processing during the operation instruction on the operation panel means is the same as the function processing during the operation resulting in the conveyance jam, the display section of the operation panel means jams the paper. Since the entire display screen is displayed, it is possible to clearly inform the operator of a paper jam based on the current function operation instruction.

Further, when the control means determines that the function processing during the operation instruction on the operation panel means is different from the function processing during the operation resulting in the conveyance jam, the display section of the operation panel means is jammed with paper. Since a part of the display screen is displayed, it is possible to clearly inform the operator of a paper jam based on a preceding functional operation instruction other than the current functional operation instruction.

By controlling in this way, for example, the currently operated screen is the copy function, and the paper jam is caused by
If the printer unit is determined and the current operation instruction function and the copy function at this time do not match, the screen shown in FIG. 18 is displayed.
In this case, since the printer unit 2 is inoperable and the copy function cannot be operated, the paper jam display screen shown in FIG. 13 is fully displayed after a certain period of time, and a reminder of the inoperable state is given. indicate. At that time, the previous screen display,
That is, you may control so that the screen switched and displayed may blink. Further, it may be controlled so that the message data registered in advance is output by voice.

In this way, the function that caused the paper jam and the place where the paper jam occurred are clarified, and by switching the screen display, different operators can easily recognize the cause of the paper jam and the error cancellation status. Is possible.
