Abstract
When a first roller is in an operation state, a driving device displaces a second displacement member in a first direction. This displaces a second locking portion of a slide portion to a position to lock a first projection portion of a first roller support member and a second projection portion of a second roller support member, while a first displacement member is held at a first position. The driving device further displaces the second displacement member in a second direction and stops the second displacement member. This allows the first displacement member to be displaced from the first position to a second position, and the second displacement member is further displaced and stopped at a position where the second projection portion is inserted in the recessed portion of the slide portion. This allows a second roller to enter an operation state.
