Abstract
PURPOSE: To prevent silicone oil from being transferred to and sticking to copying paper when the size of the paper to be passed is changed by so constituting the device that during passing of each size coping paper the separating claws located outside the width of the copying paper assume a uncontacted state.
CONSTITUTION: Four separating claws 21, 22, 23, 24 are disposed respectively to the side ends of each size of copying paper in the lengthwise direction of a heating roller 14 and the separating claws 23, 24 are coupled to solenoids 28, 29. Thereupon, at the passing of a B5 size, current is supplied to the solenoids 28, 29 according to the signal for selecting said size, then the separating claws 23, 24 are detached from the surface of the heating roller 14. At the passing of an A size, current is supplied to the solenoid 29 alone and the separating claw 24 is detached from the surface of the heating roller 14. Further at the passing of a B4 size, no current is supplied to the solenoids 28, 29 and all the separating claws make separation action. In this way, silicone oil does not deposit on the separating claws outside the width of copying paper and even if the size of the paper to be passed is changed, staining of copying paper by silicone oil does not occur.
