Abstract

PURPOSE:To easily decide whether a fault which is generated thereafter is caused by a service life of parts or not by displaying the details of periodical replacement parts on a display part by a replacing signal outputted at the time of replacement of the periodical replacement parts, and printing and recording the details of the periodical replacement parts on a printing form by a printing control part. CONSTITUTION:When periodical replacement parts reach the time of replacement, a replacing signal Vs is outputted from a replacement period managing part 1, and inputted to a display part 2 and a printing control part 3. The display part 2 displays the details of the replacement parts by the replacing signal Vs, and the printing control part 3 prints the details of the replacement parts on a printing form by the replacing signal Vs. Accordingly, when the periodical replacement parts reach the time of replacement, the details of the replacement parts are recorded on the printing form. In such a way, whether a fault generated in the course of the subsequent printing operation is caused by a service life of the periodical replacement parts or not can be decided easily.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a print display circuit, and more particularly to a print display circuit that reports the replacement timing of regularly replaced parts.

[Conventional technology]

As shown in FIG. 3, the conventional display circuit has a replacement cycle management section 1a and a display section 2a in the device.
When the replacement signal Vsa is output from the display unit 2a, the display unit 2a displays and reports the details of the regularly replaced parts.

[Problem to be solved by the invention]

However, the above-mentioned conventional display circuit,
The details of periodic replacement parts are only reported on the display, so the equipment does not stop, so if you neglect to check the display or overlook it, printing will continue, and management after replacement is not possible. Therefore, if a failure occurs, it cannot be easily determined whether or not it is due to the lifespan of regularly replaced parts.

[Means to solve the problem]

The print display circuit of the present invention includes a replacement cycle management unit that manages the replacement cycle of regularly replaced parts and outputs a replacement signal when the replacement time is reached, and displays details of the regularly replaced parts when the replacement signal is input. It is configured to include a display section and a print control section that prints details of regularly replaced parts on printing paper.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention, and FIG. 2 is a plan view showing an example of printing using the embodiment shown in FIG.

The print display circuit shown in FIG. 1 includes a replacement cycle management section I that manages the replacement cycle of regularly replaced parts and outputs a replacement signal Vs;
It is configured to include a display section 2 that displays details of regularly replaced parts when a replacement signal Vs is input, and a print control section 3 that prints details of regularly replaced parts on printing paper.

Next, the operation of the embodiment shown in FIG. 1 will be explained.

First, when a regularly replaced part reaches its replacement time, a replacement signal Vs is output from the replacement cycle management section 1 and input to the display section 2 and the print control section 3.

Next, the display unit 2 displays the details of the replacement part using the replacement signal Vs, and the print control unit 3 prints the details of the replacement part on printing paper using the replacement signal Vs.

Therefore, when a regularly replaced part reaches its replacement period, the details of the replaced part are recorded on the printing paper, so that it is easy to determine whether a failure that occurs during subsequent printing operations is due to the service life of the regularly replaced part. Can make decisions.

Incidentally, the display of regularly replaced parts can be realized by printing a numerical code in a regularly replaced parts display area 6 provided outside the printing area 5, as shown in FIG.

〔Effect of the invention〕

In the print display circuit of the present invention, a replacement signal is output from the replacement cycle management section when it is time to replace the regularly replaced parts, and based on this signal, the details of the regularly replaced parts are displayed on the display section, and the print control section displays the regularly replaced parts on the printing paper. By printing and recording the details of the replacement parts, it is possible to easily determine whether or not a failure that occurs during subsequent printing operations is due to the lifespan of the regularly replaced parts.
