Abstract

The present invention includes a supporting member that supports a first roller and a second roller, a first actuator that rotates the supporting member, a first gear that is connected to an end of second roller on the first actuator side, a second gear that is threadably engaged with the first gear, a third gear that rotates coaxially with the second gear, an input gear that threadably engages with the third gear, and a second actuator that transmits a rotational force to the input gear. The third rotation shaft extends in parallel in a first plane that includes the leading edge and the trailing edge of the nip, the first actuator rotates the supporting member between a first position at which the sheet is received from the leading edge of the nip and a second position at which the sheet is received from the trailing edge of the nip.
