Abstract

PURPOSE:To reduce the noise of a printing head in printing operation, by expanding rubber over a head cover in the printing head of a dot matrix printer. CONSTITUTION:The rubber material 3 for reducing noise is expanded by coating over the metal surface of a head cover 1 and both materials are formed in one united body. Thereby, in printing operation of a dot matrix printer, the collision sound of the core and the armature in a printing head, the noise due to the vibration of the head cover 1 generated in impact operation of the printing head pin of the printing head part 2, etc. can be absorbed to be prevented with the rubber material 3 and its low noise can be achieved.

Description

【発明の詳細な説明】 技術分野 本発明は印字ヘッドに関し、特にドツトマトリックスプ
リンタの印字ヘッドに関するものである。TECHNICAL FIELD This invention relates to printheads, and more particularly to printheads for dot matrix printers.

従来技術 従来、この種のプリンタにおいては、印字ヘッドの本体

アーマチュアの衝突音及びヘッドピンのインパクト動作
時に発生するヘッドカバーの振動音により騒音が大とな
る欠点がある。BACKGROUND ART Conventionally, in this type of printer, the main body cover of the print head is made of metal, which results in high noise during printing operations. That is, there is a drawback that noise is increased due to the collision sound between the core and the armature inside the print head and the vibration sound of the head cover generated during the impact operation of the head pin.

発明の目的 本発明は上記従来のものの欠点を除去すべくなされたも

とを一体成形した構造となっている。Structure of the Invention The print head according to the present invention has a structure in which the print head cover is coated with a noise-reducing rubber material and the cover and the rubber material are integrally molded.

実施例 以下、図面を用いて本発明の詳細な説明する。Example Hereinafter, the present invention will be explained in detail using the drawings.

形したものである。FIG. 1 is a perspective view of an embodiment of the present invention, and FIG. 2 is a perspective view of an embodiment of the present invention.
FIG. 2 is a schematic cross-section of the figure; In both figures, 1 is a head cover, 2 is a held pin portion, and 3 is a rubber material for noise reduction. This rubber material 3 is the head cover 1
The metal surface is coated with a coating, and the two are integrally molded.

騒音化が図れるのである。By doing so, the coating rubber material 3 prevents and absorbs the collision sound between the core and armature inside the print head that is generated during the printing operation of the dot matrix printer, and the noise caused by the photographing of the head cover that occurs during the impact operation of the print head bin. As a result, noise can be reduced.
