Abstract

An image recording apparatus for recording an image on a sheet includes a recording section which records the image on the sheet in a transport passage for transporting the sheet in a transport direction; and a plurality of holding members which are provided while being separated from each other in a widthwise direction of the transport passage perpendicular to the transport direction and which press the sheet transported along the transport passage, from at least one of front and back surfaces of the sheet. At lease one holding member, which is provided at a central portion in the widthwise direction of the transport passage, is arranged on a downstream side in the transport direction as compared with the other holding members.

First claim

What is claimed is:

1. An image recording apparatus comprising:
a roller pair configured to nip a sheet therebetween and transport the sheet in a transport direction;
a recording section provided downstream of a nip point of the roller pair in the transport direction and including nozzles that discharge ink to the sheet; and
a plurality of abutment portions spaced apart from each other in a widthwise direction perpendicular to the transport direction and provided between the nip point and the nozzles in the transport direction, wherein the plurality of abutment portions includes a first adjacent pair of abutment portions and a second adjacent pair of abutment portions in the widthwise direction,
wherein at least one of the plurality of abutment portions is configured to abut against an upper surface of the sheet,
wherein in a case that the sheet has a first size which is a standard size, one abutment portion of the first adjacent pair of abutment portions abuts against an edge of the sheet in the widthwise direction, and
wherein in a case that the sheet has a second size which is another standard size and different from the first size, the second adjacent pair of abutment portions does not abut against the edge of the sheet in the widthwise direction, and wherein the edge of the sheet is located between the second adjacent pair of abutment portions in the widthwise direction.

2. The image recording apparatus according to claim 1 , wherein the first size is larger than the second size in the widthwise direction.

3. The image recording apparatus according to claim 2 , wherein the one abutment portion of the first adjacent pair of abutment portions is an outermost abutment portion among the plurality of abutment portions in the widthwise direction.

4. The image recording apparatus according to claim 1 , further comprising a platen provided below the recording section and configured to support the sheet,
wherein the plurality of abutment portions are provided above the platen and abut against the upper surface of the sheet to press the sheet toward the platen.

5. The image recording apparatus according to claim 1 , wherein the first adjacent pair of abutment portions and the second adjacent pair of abutment portions do not include a common abutment portion.

6. The image recording apparatus according to claim 1 , wherein in the case that the sheet has the first size, another abutment portion of the first adjacent pair of abutment portions abuts against the upper surface of the sheet.

7. The image recording apparatus according to claim 1 , wherein in the case that the sheet has the first size, the second adjacent pair of abutment portions abuts against the upper surface of the sheet, and
wherein in the case that the sheet has the second size, the first adjacent pair of abutment portions does not abuts the upper surface of the sheet.
