DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a device that performs self-diagnosis of each function of a device or the operation of operation keys, etc., and displays the results of the diagnosis on a monitor screen or the like.

[Background Art] In devices such as image printers that have relatively complex functions and perform complex operations, it is important to check whether each function of the device or the operation of the operation keys is normal. Conventionally, diagnosis has been difficult only for professional engineers or those who are familiar with the equipment, and the more complex the equipment, the more it is necessary to operate and operate various parts. It was a time-consuming and troublesome process. Therefore, if the device outputs a video signal and has the function of displaying this video signal on a monitor, etc., for example, the device's °diagnosis menu can be displayed on the screen of the monitor, etc. If you select a diagnostic item from among them, the device will perform the operation of the selected item, or if you operate according to the menu of the selected item, the normality/abnormality of the operating point will be displayed on the screen of the monitor etc. For example, it has become possible to easily perform a self-diagnosis of the device, which can be expected to keep the device in a normal state at all times, so the emergence of a device equipped with such a function has been desired.

[Problems to be Solved by the Invention] The present invention has been made in view of the above-mentioned points. For example, in an image printer device, etc., which has a function of outputting a video signal, a video signal can be stored in the device by a required operation. The displayed self-diagnosis menu is output as a video signal and displayed on the screen of a monitor, etc., and by selecting and operating the item to be diagnosed from the displayed self-diagnosis menu, the function of the displayed diagnosis item is activated or corresponds to the display. The purpose of the present invention is to provide a self-diagnosis device that determines whether these operations are normal or not by operating keys or the like, and displays these on a screen such as a monitor.

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention provides a device that outputs a video signal and displays it on a monitor screen or the like by a required operation, and the function of each part of the device or the operation of an operation key. a memory section that stores self-diagnosis menus and discrimination standard data, etc.; an operation section that selects diagnostic items from the self-diagnosis menu stored in the memory section; and functions or operations of diagnostic items selected by the operation section. a discriminating section that compares the data with each discriminating reference data stored in the memory section to determine whether it is correct or not, and a self-diagnosis menu read out from the memory section and a signal for displaying a display based on the discrimination of the discriminating section corresponding to each diagnostic item. A display signal generating section that generates a display signal, and a control section that controls the memory section, the operation section, the discriminating section, and the display signal generating section, and outputs the signal from the display signal generating section and displays it on a monitor screen, etc. The present invention provides a self-diagnosis device configured as follows.

[Function] As configured as above, in the self-diagnosis device according to the present invention, by operating a predetermined key, the data of the diagnostic menu such as the function of each part of the device or the operation of the operation keys stored in the memory section can be retrieved. The data is read out and displayed on a monitor or other screen. If the function of the item selected from this diagnostic menu is activated or a key operation is performed according to the check list of the selected item, the operation of the key etc. is determined to be normal based on a comparison with pre-stored judgment criteria. The result of the determination is displayed on a monitor or other screen.

[Example] Hereinafter, an example of the self-diagnosis device according to the present invention will be described in detail based on the drawings.

FIG. 1 is a block diagram of essential parts of an embodiment of a self-diagnosis device according to the present invention. In the figure, 1 is the operation unit, which includes a "Diagnosis" key that is operated to switch the device to the self-diagnosis function, an "Execution" key that is used to command the diagnosis of each diagnosis item, and a command to move to the next diagnosis item. There is a ``next item'' key etc. to do this. Reference numeral 2 denotes a memory unit that stores diagnostic menu data, discrimination criterion data, and the like. 3 is the discrimination section,
It is determined whether or not the function of a diagnostic item commanded by the operation section 1 or the operation of each operation key is normal or not by comparing it with discrimination reference data stored in advance in the memory section 2. Reference numeral 4 denotes a display signal generation section which generates a display signal for displaying the data of the self-diagnosis menu read out from the memory section 2, the discrimination data of the discrimination section corresponding to each diagnosis item, etc. on a monitor screen or the like. A display section 5 displays the signal from the display signal generation section 4 on a monitor screen or the like. Reference numeral 6 denotes a control section that controls each section within the device. FIG. 2 is an example for explaining the concept of self-diagnosis menu data stored in the memory section 2, and is for a video printer device.
