【発明の詳細な説明】 〔発明の利用分野〕 本発明は印字装置に係り、特に単票類及び通帳類の印字
に好適な印字装置に関する。Description: FIELD OF THE INVENTION The present invention relates to a printer, and more particularly to a printer suitable for printing cut sheets and passbooks.
〔発明の背景〕 第３図及び第４図により従来の印字装置の説明を行う。
図中、用紙２がＡ方向に搬送され印字位置にきたとき、
ソレノイド11A,11Bが通電され、プランジや9A,9Bがレバ
ー4A,4Bに継合されて移動されることにより、レバー4A,

取りつけられているピン8A,8Bを持ち上げる。こうして
用紙２はプラテン３により用紙ガイド１に押しつけら
れ、印字ヘッド10により印字が行われる。BACKGROUND OF THE INVENTION A conventional printer will be described with reference to FIGS. 3 and 4.
In the figure, when the paper 2 is conveyed in the direction A and reaches the printing position,
When the solenoids 11A and 11B are energized and the plunge and 9A and 9B are joined to the levers 4A and 4B and moved, the levers 4A and 9B move.
4B rotates around fulcrums 6A and 6B as a center of rotation, and lifts pins 8A and 8B attached to the platen 3. In this way, the sheet 2 is pressed against the sheet guide 1 by the platen 3, and printing is performed by the print head 10.
ところが、この構造の場合、ソレノイド11A,11Bの力は
ピン8A,8Bに夫々独立して作用するので、例えば、用紙
２の巾がピン8Bの位置迄しかない場合には、プラテン３
のピン8Bの真上には押つけ力を受けるものがないため用
紙２の端部Ｃを支点としてプラテン３が反時計回りに用
紙ガイド１に当たる迄回転してしまい用紙２を用紙ガイ
ド１に均一に押つけることが出来ない。同様な原理で用
紙２の巾がピン8Bの位置迄に達しない場合、プラテン３
には前記の如く用紙２の端部Ｃを支点として反時計回り
のモーメントが働くので、ピン8A側の押つけ力が小さく
なり用紙２を均一に押しつけることが出来ない。その結
果として押つけ力不足の位置で印字不良を発生する。However, in the case of this structure, since the forces of the solenoids 11A and 11B act on the pins 8A and 8B independently, for example, when the width of the paper 2 is only up to the position of the pin 8B, the platen 3
Since there is no pressing force just above the pin 8B, the platen 3 rotates counterclockwise around the end C of the paper 2 until it hits the paper guide 1, and the paper 2 is evenly placed on the paper guide 1. Cannot be pressed against. If the width of paper 2 does not reach the position of pin 8B by the same principle, platen 3
As described above, since a counterclockwise moment acts on the end portion C of the sheet 2 as a fulcrum as described above, the pressing force on the pin 8A side becomes small and the sheet 2 cannot be pressed uniformly. As a result, printing defects occur at positions where the pressing force is insufficient.
以上のような欠点を解決する手段として、特開昭56−77
177号公報に記載されている機械にプラテンをカムによ

為のモータ等が必要となり、構造が複雑になりコスト高
となってしまう。As means for solving the above-mentioned drawbacks, Japanese Patent Laid-Open No. 56-77
A method is known in which the platen is moved up and down in parallel by driving the platen by a cam in the machine described in Japanese Patent No. 177. However, this method requires a motor or the like for driving the cam, resulting in a complicated structure and high cost.
本発明の目的は用紙巾の如何に抱らず、全巾に亘って均
一なプラテンクランプ力を簡易な横軸で得、単票及び通
帳の印字に好適な印字装置を提供することにある。It is an object of the present invention to provide a printing apparatus suitable for printing cut sheets and passbooks, which can obtain a uniform platen clamping force over the entire width with a simple horizontal axis regardless of the paper width.
プラテンのクランプは用紙巾のどの印字位置においても

プ力が得られることが望ましい。その為にはプラテンが
常に平行移動する機構となっていることが必要であり、
その手段として簡易な平行リンク方式を採用した。The platen clamp requires the minimum necessary clamping force to withstand the impact of printing at any printing position on the paper width, but if the clamping force becomes too large, the paper guide will be deformed or ghosts will be created on the carbon paper. Will be generated. Therefore, it is desirable to obtain a uniform clamping force over the entire width of the sheet. For that purpose, it is necessary that the platen has a mechanism that constantly translates,
The simple parallel link method was adopted as the means.

よる吸引が簡便である。この組合せに際し、ソレノイド

兼用させることにより簡単な平行リンククランプ機構を
得る。Further, as the source of the clamping force of the platen, suction by a solenoid is easy. In this combination, a simple parallel link clamp mechanism is obtained by using the penetrating plunger of the solenoid as the link that constitutes the parallel link mechanism.
以下、本発明の一実施例を第１図及び第２図により説明
する。第１図は側面図で、第２図は正面図である。An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. FIG. 1 is a side view and FIG. 2 is a front view.

斜することなく用紙２を均一にクランプすることができ
る。When the sheet 2 is conveyed in the direction A and reaches the printing position, the plunger 9 of the penetrating solenoid 7 is attracted in the direction of arrow B.
Both ends of the plunger 9 are joined to the levers 4A and 4B via the pins 5A and 5B. The levers 4A and 4B rotate around 6A and 6B as rotation centers, and the pins 8A and 8B attached to the platen 3 are Bring it up. In addition, the pins 6A-6B-5B-5A are parallelogrammed so that the length between 5A-5B is equal to the length between 6A-6B, and the length between 5A-6A and 5B-6B is equal, and Since the lengths of 6A-8A and 6B-8B are made equal, the platen 3 moves up and down in parallel. Therefore, regardless of the width of the sheet 2, the sheet 2 can be clamped uniformly without the platen 3 tilting.

が得られる。Further, according to the present invention, since one link of the parallel link mechanism is also used as the plunger of the solenoid, the parallel link mechanism can be configured with a simple and space-saving structure, which is uniform regardless of the paper width. Clamping force can be obtained and good print quality can be obtained on cut sheets and passbooks with different paper widths.
