Abstract
PURPOSE: To obtain always correct separation action signals, without intending to synchronize the photosensitive drum with optical scanning system, by relating the separation action signals to the movement of the optical scanning system without restricting the movement of the optical scanning system by cam plates or the like.
CONSTITUTION: When a copy button is depressed, a motor M1 starts to move, and the optical scanning system is driven by a chain 42 to commence reciprocal motions. Upon reaching the end point after scanning all the scan route, when M1 is cut off by turning off SW, a second motor M2 is started at the same time. Simultaneously, a solenoid clutch 24 is activated, so that a photosensitive drum 8 is driven through a gear box 38, and the optical scanning system also starts a returning motion. While returning, the optical scanning system continues to illuminate the original, and a protruding part 41 on the support stand 40 turns on a microswitch, out of MS2 to MS4, corresponding to the selection of variable magnification copying. After turn-on of one microswitch, a magnetic clutch 37 is activated, and a cam plate 36 starts turning. Irrespective of the motion of this optical scanning system, a microswitch MS1 is turned on after lapse of specified time. The signal obtained by this turn-on will operate the transfer paper separation device.
