Abstract

PURPOSE: To simplify constitution, and facilitate addition and changing of functions by constituting circuits through proper combination of software and hardware by the use of a microcomputer.
CONSTITUTION: A central processing unit 1 successively reads out the programs or data written into an ROM2 and makes data operation while executing prescribed sequence processing thereby performing necessary input and output controlling. External devices are a pulse motor driver part, a detecting part, an operating part, etc. The unit 1 supplies gate opening and closing signals, acceleration and deceleration signals and forward and backward revolving signals as control signals to the external devices in accordance with the input signals from the external devices. The programs or data in the ROM2 are easily rewritable. Hence, the constitution is simplified and the addition and changing of functions are made easy with this constitution.
