PURPOSE:To enhance precision of control timing, by using pulse generating means synchronized to rotation of a photosensitive drum and pulse generating means synchronized to movement of an original scanning system. CONSTITUTION:A pulse signal is obtained with discs 203, 204 rotating in synchronism to an original scanning system, and start of forward motion of the system from its home position is detected. Counting a pulse signal obtained from a disc 206 synchronized to a photosensitive drum 1 is started, and when it reaches a given number, a paper feed signal is produced. |
