Abstract (en)

A drive roller (87) and the follower roller (88) defines a nip line therebetween. A recording medium (S) has a leading edge provided with a first corner contactable with the drive roller and a second corner contactable with the follower roller at a contact line when the drive roller and the follower roller provide the nip line. A supporting unit supports the follower roller and is capable of retracting the follower roller away from the nip line in a retracting plane (L1). The retracting plane contains the axis of the follower roller. An angle ±1 and ±2 greater than the angle ±1 is defined between the retracting plane (L1) and an imaginary plane that contains the axes of the drive roller and follower roller. The supporting unit allows the follower roller to be retracted in a downstream side of the paper conveying direction with respect to the imaginary plane. The angle ±1 is greater than an angle ² defined between the imaginary plane and a radial plane passing through the second axis and the contact line.
