様な分野に使用されるものである。 Here, we will explain how this detection mechanism is used. A detection plate is fixed to a type wheel shaft that rotatably supports a type wheel. On the surface of this detection plate, conductive patterns corresponding to the number of characters arranged on the type wheel are arranged, and a detection brush is arranged in contact with the conductive patterns. When the type wheel shaft is rotated by a motor, the type wheel and the detection plate rotate in synchronization. Therefore, there is a correspondence between the characters on the type wheel and the signals obtained by the detection plate and detection brush. When printing the desired type on the type wheel, when the conductive pattern corresponding to the desired type comes into contact with the detection brush and generates a signal, electricity is applied to the electromagnet that operates the hammer, and the type is printed on the recording paper. be done. As described above, the detection mechanism of the present invention is used in such fields.
従来、検出機構に用いる検出板の表面は、素材
の表面にメツキされていたため、比較的平滑であ
つた。 Conventionally, the surface of a detection plate used in a detection mechanism was relatively smooth because it was plated on the surface of a material.
しかし、この平滑な表面の検出板はブラシ体と
の接点部において、摺動した際に発生するゴミ等
の不導体が、はさまり導通不良を起こしやすいと
いう欠点があつた。 However, this smooth-surfaced detection plate has a drawback in that non-conducting materials such as dust generated when it slides tend to get caught in the contact portion with the brush body, causing poor conduction.
またブラシ体との接点部において、平滑面同士
が接触しているため、面圧が低くなり導通不良を
起こしやすく、面圧を上げればブラシ体が摩耗し
やすいという問題点もあつた。 In addition, since the smooth surfaces are in contact with each other at the contact point with the brush body, the surface pressure is low, which tends to cause poor conduction, and if the surface pressure is increased, the brush body is likely to wear out.
本考案はこれらの欠点を解決したもので、その
目的は、検出板とブラシ体との接点部の導通を耐
久的に良好に保つことにある。本考案の他の目的
は、素材に対するメツキの密着性をよくすること
である。 The present invention solves these drawbacks, and its purpose is to maintain good continuity at the contact portion between the detection plate and the brush body for a long time. Another object of the present invention is to improve the adhesion of the plating to the material.
本考案は、検出板の導体パターン部表面に、ス
ジ目などをつけて凹凸状になしたことである。 The present invention is to make the surface of the conductor pattern part of the detection plate uneven by adding lines or the like.
以下、本考案の構成を実施例について図面に基
づいて説明する。 EMBODIMENT OF THE INVENTION Hereinafter, the structure of this invention will be explained about an Example based on drawing.

気信号を検出してゆく。 In the detection mechanism shown in FIG. 1, 1 indicates a detection plate and 2 indicates a brush body. The brush body 2 is positioned so as to be in contact with the surface of the detection plate 1, and as the detection plate 1 rotates, it passes over the conductor pattern 3 and the non-conductor pattern 4 of the detection plate 1, and receives an electrical signal. Detect it.
