The rotation mechanism, after suctioning the medium to the transporting belt to rotate in a first rotation direction to transport the medium in a first transport direction, rotates the transporting belt in a second rotation direction to transport the medium in a second transport direction to stack the medium on a stacker. The change mechanism narrows a movable area when the medium is transported in the second transport direction compared to an area when the medium is transported in the first transport direction.

Abstract: A transport roller for a printing apparatus transports a medium. The transport roller includes a shaft that extends in a direction intersecting a transport direction of the medium, and a wheel group in which a plurality of toothed wheels arrayed in the direction in which the shaft extends are held by holders. The toothed wheel includes non-formation portions having no teeth. The non-formation portions of the plurality of toothed wheels of the wheel group are arranged with an interval therebetween in a circumferential direction of the toothed wheels. The non-formation portions are cut portions that are formed when the toothed wheel is cut off from a base. The teeth other than the teeth adjacent to the cut portions are arranged away from each other at regular intervals in a circumferential direction of the wheel group.

Abstract: A transport roller, adapted to be used in a transport apparatus that transports a medium, includes a shaft, and a wheel group. The wheel group includes a plurality of toothed wheels arrayed in a direction in which the shaft extends, the plurality of toothed wheels being held by a holder which is held by the shaft. A plurality of teeth portions are provided on a peripheral surface of the wheel group, the plurality of teeth portions being disposed to be shifted in position from each other in a circumferential direction of the wheel group when the wheel group is viewed from the direction in which the shaft extends.

Abstract: A printing apparatus includes a print section, a supply path, a correction roller pair, an adjusting mechanism and a controller.
