ABSTRACT:
A switch device for an electrostatic photographic copying machine having a reciprocally movable member reciprocating from a rest position and returning thereto during each copying operation of the copying machine, and a drive driving the movable member. The switch device has an actuating member movable relative to the copying machine body and is toward a non-operating position. An operating member engages with the actuating member for moving it to an operating position. A retaining device engages the actuating member for holding the actuating member in the operating position after it has been moved to the operating position. A switch actuating the drive for the movable member is engageable by the actuating member for actuating the drive means when the movable member is in the operating position and actuating the switch for deactuating the drive when the movable member is in the non-operating position. A protuberant member movable with the reciprocally movable member engages the retaining device just prior to the return of the reciprocally movable member to the rest position after a reciprocating movement thereof for disengaging the retaining device from the actuating member, whereby when the retaining means is disengaged the actuating member is free to be moved to the non-operating position for actuating the switch for deactuating the drive.
