PURPOSE:To move an optical scanner stably and smoothly by providing a flywheel through an electromagnetic clutch to a driving system which drives the optical scanner by a motor. CONSTITUTION:Rotation driving force is transmitted to gears 33, 36 from a gear 32 fitted to the rotating shaft of a reversible motor 31, and the gear 33 rotates the flywheel 35 through the electromagnetic clutch 34. The gear 33 and flywheel 35 are engaged each other when the electromagnetic clutch 34 is on and disengaged when off. The gear 36 drives a wire drum 39 through speed reduction gears 37 and 38 and a wire 40 wound around the wire drum 39 is connected to the movable part of the optical scanner for mirrors 4-6; when the motor 31 rotates, the mirrors 4, 6, and 9 move to right or left according to the rotating direction of the motor. |
