ラテンローラを提供することにある。SUMMARY OF THE INVENTION Therefore, an object of the present invention is to eliminate such drawbacks, so that even if the surface of the platen roller receives an impact, the vibrations generated by the impact are absorbed by the outer peripheral part of the platen roller, and the rigidity of the platen roller is increased along with its rotating shaft. It is an object of the present invention to provide a platen roller whose vibration is absorbed by a rotating base integrally molded with a certain vibration damping material.

に構成する。[Means for solving the problem] In order to achieve the above object, in the present invention, in a platen roller used in a printing device such as a typewriter, the one-turn base and the rotating shaft are integrated with a rigid vibration-damping material. A hard elastic layer is provided on the outer periphery of the rotating base.

Furthermore, since it is absorbed not only by the rotating base made of the above-mentioned rigid vibration damping material but also by its rotating shaft, the vibration and noise generated by the impact during printing can be significantly reduced compared to conventional methods. can.
[実施例]
以下に、図面に基づいて本発明の実施例を詳細にかつ具
体的に説明する。[Examples] Examples of the present invention will be described below in detail and specifically based on the drawings.

いる。FIG. 1 shows an embodiment of the present invention, where l is a solid cylindrical rotating base and IA is a rotating shaft extending from both end faces thereof. Here, the rotating base 1 and the rotating shaft IA are integrally molded using a rigid damping material. That is, in recent years, it has been known that there are materials, such as cast iron and zinc-aluminum alloys, which have a high damping ability and have a vibration damping effect, in which vibration energy is consumed due to internal friction of the composition.

This configuration reduces noise and vibration caused by impact, especially on rotating bases! itself can be significantly reduced.
