<p>PURPOSE:To easily select the drive of each roller with a simple structure. CONSTITUTION:When a paper feeding roller 38 is driven, a transport roller 39 is driven synchronously with the paper feeding roller 38 by a unidirectional clutch 44. At this time, the driving force is not transmitted to a resist roller because of the unidirectional clutch 45. When the resist roller 40 is driven, the transport roller 39 is driven in synchronization with the resist roller 40 by the unidirectional clutch 45. At this time, the driving force is not transmitted to the paper feeding roller 38 because of the unidirectional clutch 44.</p> |
