ABSTRACT:
There are provided a cam23which can be rotated by a releasing motor M4, a contact/separation lever24which is moved according to the rotation of the cam23, a light shielding plate25and a cam position detecting sensor S7which detect the rotational position of the cam, and a CPU circuit unit for controlling the rotation of the releasing motor based on the detecting operation by the light shielding plate and the cam position detecting sensor. The CPU circuit unit controls the rotation of the releasing motor M4in such a manner that the cam is rotated reversely when a state detected by the light shielding plate and the cam position detecting sensor is not varied even if the releasing motor M4is controlled to be rotated.
