A sheet conveying apparatus 20 is provided with a driving portion M from which driving power is transmitted to a cam member 37a, 37b through a transmitting portion 44. Then, one of a de-curling rotary pair 23 is moved towards the other of the pair. The sheet conveying apparatus 20 further includes a restricting portion 46a that restricts the cam member 37a, 37b from turning in a direction opposite to a turning direction turned in response to a normal rotation of the driving portion M. This restricting portion 46a may comprise a one-way clutch member, and the transmitting portion may also comprise a one-way clutch. In an embodiment there are two sets of roller pairs 23, which may be arranged such that the first turns when the driving portion M rotates in a first direction, whilst the second roller pair is restricted and the first is restricted when the driving portion M rotates in the second direction, and the second roller pair turns. |
