Abstract

PURPOSE:To enable the control of a stepping motor for feeding a carrier by a microprocessor of small capacity memory by forming data for controlling time by calculation and reducing the exclusive memory locations. CONSTITUTION:In a printer which employs a stepping motor for a motor for feeding a carrier and employs a microprocessor with time interrupt at the timing of switching the excitation phase of the stepping motor and a timer capable of presetting data capable of controlling the time, STEPS A, B, C are added to the control system. The value Z set to the timer is produced by substracting the special constant N of an initial value by the value at the rising time, thereby producing a timer preset value. The step C determines the number of rises and the falls. When the rises and fall of the motor are determined by a cosine curve, the equation is calculated with respect to the Z, and the result is preset at the timer.
