本発明はワイヤ式ドツトプリンターヘッドに関するもの
である。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a wire-type dot printer head.

印字する。Conventionally, as shown in FIG. 5, when the drive coil 52 inserted into the coil core 31 is energized, the actuator 3S is guided by the actuator guide S4 and supported by the fulcrum spring 35 so as not to interfere with the actuators on both sides. The print wire 36, which is attracted to the fulcrum and is engaged with one end of the actuator 33, is also driven in the direction of the arrow, colliding with a platen (not shown) and printing.

6 is returned and held in a standby state by a repulsive force from a clay platen (not shown), the spring force of a return spring 37, and a damper 38 as a stopper of the actuator.

して衝撃音を発し復帰する。Thereafter, the print wire 36 prints by repeating this process. However, in the above-described printing state, there is an impact sound when the actuator 33 is attracted by the coil core 51, an impact sound when the actuator collides with the print wire 56, and a repulsive force from the platen (not shown) and a return spring. The spring force of 37 causes the pulley wire to return and collide with the actuator, producing an impact sound. Further, the actuator collides with the damper 58 due to the impact force of the print wire and the spring force of the return spring, and returns with an impact sound.
このように各々の動作において衝撃音を発するため、防
音カバー３９を取り付は衝撃音を外部へでないよう工夫
しである。Since impact sounds are generated in each operation as described above, the soundproof cover 39 is installed in a way that prevents the impact sounds from going outside.
しかし、前述第５図に示す従来技術ではヘッドを構成す

が高く問題がある。又、部品点数が多いためにヘッドの
小型化への障害となっている。However, in the prior art shown in FIG. 5, the number of parts constituting the head is large, resulting in a large number of assembly steps and a high price. Furthermore, the large number of parts is an obstacle to miniaturization of the head.
本発明は、このような問題に鑑みてなされたもので、そ

トドツトヘッドを提供することにある。The present invention was made in view of these problems, and its purpose is to provide a soundproof cover, an actuation guide, and a fulcrum pressing spring. Providing each function of the damper and making it into a body reduces the number of parts and improves ease of assembly! It is possible to reduce the price by making it an i element, and by providing the above-mentioned integrated soundproof cover with an operating guide and a fulcrum pressing spring part, it is easy to assemble, and the volume is reduced, so it provides a small impact dot head at a low price. There is a particular thing.

せたことを特徴とする。The present invention relates to a wire dot printer head. All four parts and four functions of the actuator operation guide, the fulcrum pressing spring that supports the actuator's operating fulcrum, and the soundproof cover that prevents rebound when the actuator returns after printing are integrated into the soundproof cover. It is characterized by

こともあって、製品の低価格、小型化が可能となる。According to the above-described structure of the present invention, a soundproof cover for preventing the noise originally generated during printing, an actuator operation guide, and a fulcrum pressing spring that supports the operation fulcrum are provided. Since the damper function that prevents rebound can be manufactured by body molding using non-gold jig (for example, resin such as polycarbonate), the number of assembly steps is greatly reduced, and there is no possibility of malfunction due to parts not being inserted during assembly or of automatic assembly machines. Problems such as a decrease in operating rate are eliminated, and the number of parts can be reduced by integrating the parts, making it possible to reduce the price and size of the product.

The actuator 5 is inserted into the intermediate guide 3 and pressed by the return spring 4, and the pressed actuator 5 is supported by the fulcrum pressing spring part 10 of the soundproof cover 6 that supports the actuation fulcrum, and the actuator plate guide part of the soundproof cover 6 is used as a guide. , it is pressed against the damper portion 12 of the soundproof cover 6 and enters a standby state. The actuator 5 is guided by the actuating plate guide portion 11 and is attracted by the coil core 7 and collides with the printed wire 1.
The print wire 1 collides with a platen (not shown) to print.
