Abstract

PURPOSE:To prevent the temperature inside a printing head from rising to enable continuous printing and also to increase printing speed by providing a heat sink with a water jacket. CONSTITUTION:A printing head performs printing by means of the tip of a print wire 1a through a ribbon 4 by releasing an armature assembly 1 which is being attracted by a magnet 3 by electrifying a coil 2, wherein the printing head can be prevented from being heated by providing a heat sink 6 with a water jacket.

Description

【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、印字ヘッド、特に、ドツトシリアルプリンタ
に使用する印字ヘッドに関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to printheads, and particularly to printheads for use in dot serial printers.

〔従来の技術〕[Conventional technology]

従来の印字ヘッドはヒートシンクとファンにより発熱を
おさえ印字ヘッド内の温度が８０℃になるとインシュレ
ーターにより印字しないようになっていた。Conventional print heads use heat sinks and fans to suppress heat generation, and an insulator prevents printing when the temperature inside the print head reaches 80°C.

〔発明が解決しようとする課題〕[Problem to be solved by the invention]

しかしながら、このような上述した従来の印字ヘッドは
、ヒートシンクとファンだけとなっているので印字ヘッ
ド内の温度があがりすぐに印字ヘッドがとまってしまう
という欠点がある。However, since the above-mentioned conventional print head has only a heat sink and a fan, the temperature inside the print head rises and the print head stops immediately.

〔課題を解決するための手段〕[Means to solve the problem]

本発明の印字ヘッドは、ヒートシンクにウオタージャケ
ットを取り付けて構成される。The print head of the present invention is constructed by attaching a water jacket to a heat sink.
