Abstract

There is provided an image recording apparatus including: a conveyer configured to convey a sheet in a conveying direction; a head configured to discharge a liquid toward the sheet; a heater configured to heat the sheet and/or the liquid on the sheet; a reader positioned downstream in the conveying direction of the heater, the reader being configured to read an image, on the sheet, formed by the head and the heater; and a holder positioned between the reader and the heater in the conveying direction, the holder being configured to hold a body of rotation configured to contact a recording surface of the sheet. In a crossing direction orthogonal to the conveying direction and crossing the recording surface of the sheet being conveyed by the conveyer, both ends in the crossing direction of the holder are positioned outside of both ends in the crossing direction of the reader.

First claim

What is claimed is:

1 . An image recording apparatus comprising:
a conveyer configured to convey a sheet in a conveying direction; a head configured to discharge a liquid toward the sheet; a heater configured to heat the sheet and/or the liquid on the sheet; a reader positioned downstream in the conveying direction of the heater, the reader being configured to read an image, on the sheet, formed by the head and the heater; and a holder positioned between the reader and the heater in the conveying direction, the holder being configured to hold a body of rotation configured to contact a recording surface of the sheet, wherein in a crossing direction orthogonal to the conveying direction and crossing the recording surface of the sheet being conveyed by the conveyer, both ends in the crossing direction of the holder are positioned outside of both ends in the crossing direction of the reader.

2 . The image recording apparatus according to claim 1 , wherein the holder includes a first wall positioned upstream in the conveying direction of a rotation axis of the body of rotation and extending in the crossing direction, and a second wall positioned downstream in the conveying direction of the rotation axis of the body of rotation and extending in the crossing direction.

3 . The image recording apparatus according to claim 2 , wherein the first wall and the second wall extend in a first direction crossing the conveying direction and crossing the crossing direction.

4 . The image recording apparatus according to claim 3 , wherein the holder further includes a third wall closing a space between a first end in the crossing direction of the first wall and a first end in the crossing direction of the second wall, and a fourth wall closing a space between a second end in the crossing direction of the first wall and a second end in the crossing direction of the second wall.

5 . The image recording apparatus according to claim 4 , wherein a slit is formed in the third wall; and
a part of the body of rotation protrudes to outside of the third wall via the slit.

6 . The image recording apparatus according to claim 5 , wherein a cleaner configured to make contact with the body of rotation is positioned between the first wall and the second wall.

7 . The image recording apparatus according to claim 6 , wherein the cleaner is aligned with the body of rotation in the crossing direction.

8 . The image recording apparatus according to claim 1 , further comprising a frame configured to support the holder,
wherein the holder is detachably attached with respect to the frame.

9 . The image recording apparatus according to claim 3 , wherein both ends in the first direction of the first wall are positioned outside, respectively, of both ends in the first direction of the heater.
