A plurality of restricting members are provided in one to one correspondence with the drive transmitting members. Each restricting member moves between a first position and a second position and restrictes the shifting of the corresponding drive transmitting member when in the first position. A single moving member is provided for the plurality of drive transmitting members. The moving member moves the plurality of restricting members between the first position and the second position.
