Abstract:
1. A recording medium transport device, comprising: a transport driving roller rotatably driven; a transport driven roller that can be driven to rotate for nipping a recording medium between with the transport driving roller; a driven roller supporting member for pivotally supporting the transport driven roller and provided so as to be able to be displaced; adjusting member for adjusting the angle α made by a straight line passing the rotation axis line position of the transport driving roller and the rotation axis line position of the transport driven roller and a straight line parallel to the gravity direction; and controlling member for reducing the angle α by controlling the adjusting member after a leading edge of the recording medium has passed through the nip point and before the back end of the recording medium is passed through the nip point of the transport driving roller and the transport driven roller based on the information from detecting member for detecting the position of the recording medium on the transport pathway.
