Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording apparatus, and more particularly, to a recording apparatus having a discharge mechanism for transporting a sheet by sandwiching the sheet between a first discharge member and a second discharge member. .

[従来の技術] 従来のインクジエツトプリンタを第2図に示す。[Prior Art] FIG. 2 shows a conventional ink jet printer.

In FIG. 2, a sheet inserted from A by a manual feed or a cut sheet feeder (not shown) is guided by a paper pan 4 by a feed roller 1 and pinch rollers 2 and 3 pressed against the feed roller 1 to feed the sheet. The pressing plate 5 is set without floating on the platen 6.

Then, printing is performed on the sheet by discharging ink from the print head 8 on the carrier 7, and the sheet is pressed against the discharge roller 9 by the discharge roller 9 and the spring 17.
It is raised by 10 and discharged to the statka S.

[Problems to be Solved by the Invention] As shown in FIG. 2, on the printing surface side of the discharge mechanism, a roller is used instead of a roller. This is because the ink is not dry and cannot be contacted by the roller on the printing surface immediately after printing, so that the ink other than the printing portion is prevented from adhering by point contact with a wheel.

However, as shown in FIG. 3, for example, in the case of a φ10 (diameter 10 mm) wheel car divided into 40 equal parts, the pitch of the projections is
The distance from the tip of the protrusion that presses the paper to the roller on the non-printing surface side to the next protrusion is large, causing a disturbance in the paper feed pitch.

そのため、突起ピツチを小さくするべく、たとえばφ

Therefore, in order to reduce the projection pitch, for example, φ
In the case of dividing by 100 into 100, the tip of the projection becomes sharp and a hole is formed in the paper. On the other hand, the tip (φ10) and bottom (φ
If the difference in 9.3) is made small, the paper is close to line contact with the paper, and the function of the aster wheel cannot be exhibited.

In addition, even if the pressing force on the roller on the non-printing surface side of the wheel is increased in order to improve the paper feeding accuracy, the pressure on the paper at the tip of the projection increases, leaving a mark on the paper or opening a hole. Would.

[Means and Actions for Solving the Problems] The present invention has been made in view of the above-mentioned problems, and the configuration of the present invention is such that a sheet is sandwiched between a first discharging member and a second discharging member. In a recording apparatus having a discharge mechanism for transporting, the first discharge member that contacts a surface on which a sheet is recorded has a plurality of rows of protrusions in which a plurality of protrusions are arranged in a circumferential direction, and the rows of protrusions are spaced from each other. , And the projections in one row are circumferentially shifted from the projections in another example.

これにより、細かい突起ピッチが得られ、用紙の搬送
が安定する。
Thereby, a fine projection pitch is obtained, and the conveyance of the paper is stabilized.

[実施例] 以下、図面を参照して本発明を具体的に説明する。EXAMPLES Hereinafter, the present invention will be described specifically with reference to the drawings.
