Abstract

PURPOSE:To obtain copied image of high quality by controlling the turning speed of a DC motor, driving a separating belt, by the output of a speed detector coupled with the DC motor. CONSTITUTION:An encoder 10 for speed detection is coupled with a DC motor 9 which drives a separating belt 3. The output of the encoder 10 is inputted to an error amplifier 12 through an F-V converter 13 to be compared with a reference voltage from a reference power source 11. Their difference output is passed through a power amplifier 14 to drive the DC motor 9 at a constant speed. Consequently, copied images of high quality are obtained.
