Abstract
First and second driving systems are driven by a first motor via first and second planetary mechanisms through motor rotation in first and second directions, respectively. A third driving system is driven by the second planetary mechanism through motor rotation in the first direction. A switching mechanism switches a transmission path for the motor driving force by inhibiting one of the first and second planetary mechanisms from revolving, and causes the other of the first and second planetary mechanisms to transmit the driving force through a transmission path selected by the switching. First and second restraint members of the first and second planetary mechanisms, respectively, restrain the respective mechanisms from revolving simultaneously by inhibiting engagement of the first and second planetary mechanisms with the second and third driving systems, respectively.
