Abstract

PURPOSE:To obtain a print character having a high resolution, by making the cross-section of a printing section of a dot wire into a shape of polygonal. CONSTITUTION:A print head comprises a dot wire 1, an armature 2, a solenoid 3, a guide 4 and an anti-rotation guide 5, where the cross-section of the dot wire 1 is made octagonal. When printing is made, the wire dot 1 is driven by the solenoid 3 through the armature 2. The dot wire 1 is held at a predetermined position by means of the guide 4 and the anti-rotation guide 5 is arranged in contact with one face of the dot wire 1, so as to hold the horizontal, vertical and oblique faces of the dot wire 1. Since the dot wire 1 is octagonal, the border section of the print will be a continuous line when a printing is made so that dots are overlapped slightly each other, thereby a print character having a high resolution can be obtained.

Description

The cross-sectional shape of the printing portion of the dot wire used in the print head of this impact type dot matrix printer is circular or square.

従来技術では、インパクト形ドットマトリクス・プリン
タの印字ヘッドに使用するドツトワイヤの印字部の断面
形状が円形、あるいは四角形であるため、ドツトで文字
を構成する場合、文字の水平。In the conventional technology, the cross-sectional shape of the printing part of the dot wire used in the print head of an impact-type dot matrix printer is circular or square, so when a character is composed of dots, the character is horizontal.

ッドが大型化し、また、印字速度が低下するという問題
があった。The vertical and diagonal boundary portions are a series of circular arcs or chevrons as shown in FIG. 3, making it impossible to obtain printed characters with high resolution. Furthermore, in order to improve the resolution, it is possible to increase the number of dots that make up a character, but while this method improves the resolution, it also increases the size of the print head and reduces the printing speed. Ta.

がある。Means for Solving Problem C] In order to achieve the above object, the print head of the present invention is a print head for an impact-type dot matrix printer equipped with a dot wire for printing dots, in which the cross-sectional shape of the printing portion of the dot wire is The feature is that it is a polygon.

〔作用〕[Effect]

本発明においては、多角形のドツトワイヤの各辺が水平
、垂直、および斜め方向に対して、境界部分を構成する
ため、ドツトが相互に、少しづつ重なる様に印字すると
、印字の境界部分は直線の連続となり、解像度が高い印
字文字を得ることができる。In the present invention, each side of the polygonal dot wire constitutes a boundary in the horizontal, vertical, and diagonal directions, so if the dots are printed so that they overlap each other little by little, the boundary of the printing will be a straight line. It is possible to obtain printed characters with high resolution.
