PURPOSE:To facilitate the adjustment for different moving speeds of an exposure device, by providing driving motors independently for a photosensitive drum and the exposure device. CONSTITUTION:A common driving motor 16 is used for a mirror driving exposure device E1 and an original driving exposure device E2 different in speed, and a motor 12 is used to drive a drum 1. When signal ''1'' is inputted to an input terminal 14 of a speed setting part 13, the mirror driving exposure device E1 is driven through a controller 15, a motor 16, a clutch C1, and a transmitting mechanism D1, and the speed is adjusted by a variable resisance VR1. When an original transfer device 7 is moved to the position indicated by the broken line, a mirror is set to the position indicated by the broken line also. When the signal of level 0 is inputted to the input terminal 14, the original driving exposure device E2 is driven through the controller 15, the motor 16, a clutch C2, and a transmitting mechanism D2, and the speed is adjusted by a variable resistance VR2. |
