て正確に搬送することが必要になる。2. Description of the Related Art An ink jet recording apparatus used as an image recording apparatus (image forming apparatus) such as a printer, a facsimile, and a copying apparatus discharges ink droplets from nozzles (ejection ports) of an ink jet head to record paper (image). This means that the image is recorded on paper.) If the relative positional relationship between the recording head and the paper deviates, the image quality deteriorates. It will need to be transported.

波打ちが大きくなると用紙とヘッドとが接触して異常画
像やヘッドの損傷が発生する。Further, in the ink jet recording apparatus, since ink droplets are adhered to paper for recording, the paper is likely to undulate (cockling) during printing, thereby ensuring the flatness of the paper with respect to the head. If not, the gap between the paper and the head will vary, disturbing the image,
When the waving becomes large, the sheet comes into contact with the head, and an abnormal image or damage to the head occurs.

能領域（所謂先端余白、後端余白）が大きくなる。However, in an ink jet recording apparatus in which transport rollers are arranged on the upstream and downstream sides of the paper transport, printing is performed with the leading and trailing edges of the paper held by the transport rollers. Since printing must be performed, the non-printable areas (the so-called leading and trailing margins) at the leading and trailing edges of the sheet are increased due to layout restrictions.

8b. The rib 28 of the printing receiving member 27
a and 28b are formed at substantially equal intervals in the width direction of the sheet.
The rib 28b slightly inside the widthwise end of the paper as shown in FIG.
Is formed to be lower than the height of the other rib 28a (about 1 mm).

される。In this ink jet recording apparatus,
The paper 3 sent out from the transport roller 24 is transported along the rib 28a of the print receiving member 27 as shown in FIG. Ink droplets ejected from 14 are attached.

張られ、用紙の両端部側が上に膨らむためである。Here, a cockling phenomenon occurs in which the paper swells within a few seconds after the ink droplets adhere to the paper. Normally, both ends of the sheet in the width direction are swollen by the cock ring. That is, when an image is recorded on a sheet of paper, a margin, which is a non-printing portion, is always formed on the top, bottom, left, and right of the sheet. This is because the ink at the printing portion is pulled to dry, and both ends of the paper swell upward.

汚したりヘッドが傷ついたりする。For this reason, as shown in FIG. 5, when only the rib 28a for defining the gap is provided on the printing receiving member 27 (when the height of the rib is constant), the recording head 14 is not used.
Interferes with the swollen portions at both ends of the paper 3, thereby soiling the paper or damaging the head.

止できる。Therefore, a rib 28a for defining a gap is provided in the printing receiving member 27 as in the present embodiment, and the height of the rib 28b slightly inside both ends in the paper width direction is set lower than the rib 28a. By doing, Figure 6
As shown in FIG. 6, the paper 3 swelled by the ink droplets falls down at the rib 28b, the upward swelling of both ends of the paper 3 can be suppressed, and the interference with the recording head 14 can be prevented.

This will be described with reference to FIG. In the present embodiment, a plurality of ribs 28a are provided on the printing receiving member 27, and the interval between the ribs 28a is widened at a portion slightly inside from both ends in the paper width direction. As a result, as shown in FIG. 8, the paper 3 swelled by the ink droplets drops at a portion where the interval between the ribs 28a is wide, and the upward swelling of both ends of the paper 3 can be suppressed. Interference can be prevented.

And a rib 2 at a portion slightly inside from both ends in the paper width direction.
8b is lower in height and wider than the other ribs 28a. As a result, as shown in FIG. 10, the paper 3 swollen by the ink droplets falls at the portion of the rib 28 b having a low height and a wide interval, and the upward swelling of both ends of the paper 3 can be suppressed. Interference with the recording head 14 can be prevented.
