Abstract
PURPOSE:To enable the simple counting of the number of copying sheets by making use of the register function, operation function and display function possessed by an LSI exclusive for electronic calculators. CONSTITUTION:The register function and display function of an LSI exclusive for electric calculators are straightly used for the register and display of the number of copying sheets by the key inputting from a key input unit 1. Function key operations are done according to mechanical operations by the signal from the muCPU4 being the control part for controlling the main copying sequence and the addition or subtraction of the number of copying sheets are done by the operation function of the LSI2. Namely, in the case of making subtraction from the number of copying sheets having been registered, the key input pulse instructing the subtraction is subsequently sent to the LSI2 from the muCPU4 every time when one sheet of copy is taken. Then, the operation of the number of copying sheets is done automatically by the LSI2 and the results thereof may be displayed in a display part 3.
