Abstract
PURPOSE:To render the structure of a copying device simple and compact, by driving each drive system with each independent motor rotating at its given rotation ratio in accordance with each rotation speed detected. CONSTITUTION:Each drive system is driven with each independent motor, such as motor 60 for optical scan driving, motor 61 for driving a photosensitive drum, motor 62 for driving a fixing unit, or motor 63 for driving a developing unit. These motors 60-63 each has slit disc 70, light emitting and receiving elements 72, 73, a light converging glass fiber transmitter, etc., and detects its rotation speed. These motors 60-63 are regulated to render their rotation ratios constant and each drive system is always synchronously driven. This method permits clutches, chain transmission mechanisms, etc. to be unnecessary and each motor size to be reduced, and thus, the copying device to be of high precision, simple and compact in structure.
