Digital display device controlled by a microcomputer

摘要

There is disclosed a display device for a copier, such display unit being provided with a display generator which generates signals at a determined time interval. A microcomputer is provided with a program interruption port for receiving the signal from the signal generator and performs dynamic drive of the display unit by the signal. The dynamic display control is achieved by interruption signals externally supplied at a determined time interval to the computer. Therefore, a constant display drive timing is maintained regardless of the execution time of the main program and an ensured dynamic display control without flicker in display is obtained.
