发明名称 MAINTENANCE CONTROL CIRCUIT OF INFORMATION PROCESSOR
摘要 PURPOSE:To perform the displays of a previous announcement and an alarm by setting optionally the previous announcement value and the alarm value in accordance with the exchanging cycles of consumption and periodical exchange parts of an information processor and comparing these set values with the integration information value. CONSTITUTION:The integration information 14 on the power supply application time, the number of print sheets, etc. is supplied to an integrated integration circuit 7 and a comparison integration circuit 4. The output of the circuit 7 is supplied to an integrated integration display circuit 11 and displayed as the previous sum total. While the comparison integration information 15 on the output of the circuit 4 is supplied to a previous announcement comparator 8 and compared with the previous announcement information 16, i.e., the output a previous announcement setting circuit 5. While the information 15 is supplied to an alarm comparator 9 and compared with the alarm information 17, i.e., the output of an alarm setting circuit 6. When the information 15 is equal to or larger than the information 16 in terms of the result of comparison of the comparator 8, a previous announcement display part 12 of a display panel 10 glows. While an alarm display part 13 of the panel 10 glows when the information 15 is equal to or larger than the information 17 in terms of the result of comparison of the comparator 9. Thus the time of exchange is shown for consumption and periodical exchange parts.
