Abstract

A recording device includes a transport unit, a medium supporting member, and a recording head. The transport unit includes transport roller pairs and discharge roller pairs. The discharge roller pair includes a discharge driving roller and discharge driven rollers provided downstream of the medium supporting member in a transport direction. The transport unit includes a first roller and a second roller, which are an example of a guide roller provided downstream of the medium supporting member in the transport direction and on the same upper side as the discharge driven roller with respect to a transport path of a medium. The first roller and the second roller are provided on either side of the discharge roller pair in the transport direction, and a lower end of at least one of the first roller and the second roller is positioned lower than an upper end of the discharge driving roller.

First claim

What is claimed is:

1 . A recording device including a transport unit that transports a medium along a horizontal direction in a transport direction, a medium supporting member that includes a supporting surface supporting the medium, and a recording head that performs recording on the medium at a position facing the medium supporting member, wherein
the transport unit includes a transport roller pair formed of a transport driving roller and a transport driven roller provided upstream of the medium supporting member in the transport direction, a discharge roller pair formed of a discharge driving roller and a discharge driven roller provided downstream of the medium supporting member in the transport direction, and a guide roller provided downstream of the medium supporting member in the transport direction, and on the same upper side as the discharge driven roller with respect to a transport path of the medium, and driven to rotate by contact with the medium during transport, and the guide roller is provided on both sides of the discharge roller pair in the transport direction or on both sides of the driven discharge roller in a width direction intersecting the transport direction, and, a lower end of at least one of the guide rollers on the both sides of the discharge roller pair in the transport direction is positioned lower than an upper end of the discharge driving roller.

2 . The recording device according to claim 1 , wherein
the guide roller is provided on both sides of the discharge roller pair in the transport direction, the guide roller is a first roller disposed upstream of the discharge roller pair in the transport direction, and is a second roller provided downstream of the discharge roller pair in the transport direction, and a lower end of the second roller is positioned lower than the upper end of the discharge driving roller.

3 . The recording device according to claim 2 , wherein
a lower end of the first roller is positioned lower than the upper end of the discharge driving roller.

4 . The recording device according to claim 2 , wherein
a difference in dimensions, in a vertical direction, between a lower end of the first roller and the lower end of the second roller is no greater than an overlap amount, in the vertical direction, between the second roller and the discharge driving roller.

5 . The recording device according to claim 2 , wherein
the second roller is disposed in a position corresponding, in the width direction, to a position between the discharge driven rollers.

6 . The recording device according to claim 2 , wherein
positions of the first roller and the second roller are the same in the width direction.

7 . The recording device according to claim 2 , wherein
the first roller is urged downward by a first urging force while being upwardly displaceable, and the second roller is urged downward by a second urging force while being upwardly displaceable, the discharge driven roller is urged downward toward the discharge driving roller by a third urging force while being upwardly displaceable, and the first urging force of the first roller and the second urging force of the second roller are smaller than the third urging force of the discharge driven roller.

8 . The recording device according to claim 2 , wherein
a second distance, in the transport direction, between the second roller and the upper end of the discharge driving roller is shorter than a first distance, in the transport direction, between the first roller and the upper end of the discharge driving roller.

9 . The recording device according to claim 2 , wherein
the medium supporting member alternately includes ribs and recessed regions in the width direction, the ribs including the supporting surface supporting the medium and the recessed regions being formed in regions other than the ribs, and a position of the second roller in the width direction is the same as a position of the recessed region.

10 . The recording device according to claim 2 , comprising:
a pressing member configured to press the medium to a position lower than the supporting surface of the medium supporting member, at a position upstream of a recording position of the recording head in the transport direction, wherein the second roller is disposed at a position that is the same, in the width direction, as a position of the pressing member.

11 . The recording device according to claim 1 , wherein
the guide roller is provided on both sides of the discharge driving roller in the width direction, and a lower end of the guide roller is positioned lower than an upper end of the discharge driving roller.
