Title: Image forming device
Inventor: TANIMOTO YASUFUMI
IPC: G03G15/00
Filed: 1990-03-05
Abstract: PURPOSE:To easily and effectively reduce rotational irregularity or vibration by changing a time interval that the excitation of an exciting coil is switched corresponding to the speed change of a stepping motor with the aid of giving periodicity to it. CONSTITUTION:The integer value of a value obtained by dividing respective excitation time by a reference clock from an oscillator 350a is stored by the stepping motor S of an engine control circuit. An excitation register 359 is latched by a latch signal from a CPU 350 and supplied to the excitation circuit 306b (306c) of a mechanism part driving circuit. That means, the inherent speed change of the stepping motor S is stored and taken as a time interval value which is set so as to cancel the change based on the data imitating the change of a sinusoidal state as much as one period and so as to make the speed of the motor S the speed of an opposite phase by considering the amplitude of the speed change of the speed change data of the speed T4 of the motor S where the value is offered to be used. Thus, the speed change of the stepping motor is easily and effectively reduced.
