Abstract
Description
【発明の詳細な説明】 ［産業上の利用分野］ 本発明はプリンタの用紙送り機構の改良に関する。[Detailed description of the invention] [Industrial application field] The present invention relates to improvements in paper feeding mechanisms for printers.
［従来の技術］
従来、連続用紙を印字部からできるだけ近い位置で切断

ものがあった。The printing paper 13 is sent out very close to the printer head 14 and cut by a cutter 15 using a bin feed platen 12 embedded with a bin feed platen 12, or the printing paper 13 is fed to the platen 1 by a bush tractor 16 as shown in FIG. In some cases, the paper is pushed along the paper guide 17 from the rear of the paper 1 and cut at the rear vine 15 of printing by the printer head 14.
［解決すべき問題点］
上述したビンフィードプラテン１２を用いる機構の場合

う欠点があった。[Problems to be Solved] In the case of the mechanism using the bin feed platen 12 described above, the bins 11.11. , is a part of the platen 10,
Bin! 1.11. ．．
．． There was a drawback that the paper width was fixed and only one width of paper could be used.
また、ブツシュトラクタ１６を用いる機構の場合は、印

れたり、用紙ジャムが発生することが多かった。In addition, in the case of a mechanism using a bush tractor 16, the printing paper 13 is pushed and fed by the tractor 16, and the paper winding angle of the platen 10 is large, which places a load on the printing paper 13.
After cutting the printing paper 13 in the cutting section, the primary printing position often shifts or paper jams occur.
その対策として、第４図にも示した様に印字部の直後に
用紙送りローラ１８を配置し、印字用紙１３を引き上げ

した送り性能を保持出来ないという欠点があった。As a countermeasure against this, as shown in FIG. It is difficult to balance the gap with the IO, the feed amount of the roller 1B and the tractor 16, etc.
This method requires adjustment depending on the type of paper, such as paper thickness, and has the disadvantage that stable feeding performance cannot be maintained.

字位置まで送り出す構成である。[Means for Solving Problems] - The paper feeding mechanism of the printer of the present invention which solves the conventional problems feeds continuous paper between a platen and a printer head, and after printing by the printer head,
Platen] In a printer that cuts the continuous paper in two parts, the continuous paper is first drawn into the platen part before the start of the next printing, and then sent out to the printing position by the printer head.

A printer head 6 is disposed facing the platen 1, a car 2 is disposed above the platen 1, and a tractor 3 is disposed immediately behind the platen 1. After the printing paper 5 is set on the tractor 3, it passes between the paper guide 4, the printer head 6, and the platen 1 for printing, and is further sent above the cutter 2 to be cut.

After drawing the position platen to the first part, it is controlled to send it out to the printing position.

It is possible to remove the slack in the paper between sheets, and it has the effect of stabilizing the next printing position after cutting the continuous paper regardless of the paper type.
