  • Connection device, image forming apparatus and optional device equipped with the same
    Patent number: 7287998
    Abstract: A connection device includes a fixed locking member that is connected electrically to a conductive first frame of a post processor, and a conductive movable locking member that contacts an outer face of the fixed locking member and can slide. A conductive positioning pin that is connected electrically to a conductive second frame of a copying machine is inserted in a pin insertion hole and a large diameter portion in an unlock position of the movable locking member. When the movable locking member is further moved to slide to a lock position, the positioning pin is engaged and fixed to a small diameter portion, so that a conductive plate spring of the movable locking member contacts the positioning pin.
