本発明は、印字用紙押さえを持たない印字装置において
、連続した印字用紙へ印字する際の印字精度、及び、印
字速度の向上を図るのに好適な手段に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention is aimed at improving printing accuracy and printing speed when printing on continuous printing paper in a printing device that does not have a printing paper holder. Concerning preferred means.
(従来の技術〕
従来の装置は、実開昭62−157248号公報に示さ

公報は印字速度の低下に対する考慮がされておらず、処
理能力低下の問題があった。Publication No. 15724JI does not take into consideration the conveyance of the printing paper after passing the printing mechanism when it does not have a printing paper holder. There were problems such as skewing due to interference with the head. Furthermore, Japanese Patent Application Laid-Open No. 56-38688 does not take into consideration the reduction in printing speed, and there is a problem in that the throughput is reduced.
本発明の目的は、印字用紙押さえを持たない印字装置に
おいて、処理能力(印字速度)を低下させることなく、
印字用紙のジャムや、斜行を防ぎ印字精度を向上させる
ことにある。An object of the present invention is to provide a printer that does not have a printing paper holder without reducing processing capacity (printing speed).
The purpose is to prevent printing paper from jamming and skewing and improve printing accuracy.
上記目的を達成するために、本発明は印字用紙位置を常
に監視し、すなわち、印字用紙の送り量をカウントし、
特定範囲内にある場合は、印字用紙を搬送する際に印字
ヘッドを印字用紙の中央に移動させる手段を設けた。In order to achieve the above object, the present invention constantly monitors the printing paper position, that is, counts the feeding amount of the printing paper,
If it is within a specific range, a means is provided for moving the print head to the center of the print paper when the print paper is conveyed.
印字ヘッドは先端が平坦であるため、印字用紙をプラテ
ンに押さえ付けるのに適した形状をしており、印字用紙
の中央に位置させることにより、カッタとの干渉が無く
なり、ジャムの発生を防ぐことができる。また、印字ヘ
ッドとの干渉が印字用紙上、左右対称となるため、印字
用紙の斜行も防ぐことができる。Since the print head has a flat tip, it has a shape suitable for pressing the print paper against the platen, and by positioning it in the center of the print paper, there is no interference with the cutter and jams can be prevented. I can do it. Furthermore, since interference with the print head becomes symmetrical on the print paper, skewing of the print paper can also be prevented.
また、印字用紙の位置を、常に、監視し、特定範囲内に
ある場合のみ印字用紙の中央に位置させると共に、搬送
速度を下げないため、印字速度(処理能力)の低下を防
ぐことができる。In addition, the position of the printing paper is constantly monitored, and only when the position is within a specific range, the printing paper is placed in the center, and the conveyance speed is not lowered, so it is possible to prevent a reduction in printing speed (processing capacity).
