この発明は、サーマルヘッドを備えたプリンター装置の
輸送時等にサーマルヘッドを固定する固定構造に関する
。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a fixing structure for fixing a thermal head during transportation of a printer device equipped with the thermal head.

支承している。Figure 2 shows the fixing structure of a conventional thermal head. (1) is the thermal head, (lal is its rotation axis,
(lbl is an arm, (2) is a platen, and (3) is a cushion made of foamed resin, which is inserted between the thermal head (1) and the platen (2) to support the thermal head (1). .

) presses the ink sheet (4) and paper (5) against the platen (2) by receiving a rotational force in the b direction about the shaft (1a), and prints by being energized.
次にクツション（３）の作用について説明する。Next, the action of the cushion (3) will be explained.

でなく、輸送中にサーマルヘッドｆ１１に加わる振動を
吸収する役目も果たしている。If strong vibrations are applied to the printer device during transportation, the thermal head (11) will strongly hit the platen (2), causing damage or loss of accuracy. It is inserted between the thermal head (11) and the platen (2) to prevent collisions between the thermal head (m) and the platen (2), and also absorbs vibrations applied to the thermal head (f11) during transportation. It also plays a role.
［発明が解決しようとする課題〕
従来のサーマルヘッド固定構造は以上のように構成され
ているので、長期使用時や劣悪な環境下での輸送時には
、クツション（３）に永久変形が生じ、緩衝材としての
役目を果たさなくなる場合がある。[Problems to be Solved by the Invention] Since the conventional thermal head fixing structure is configured as described above, the cushion (3) undergoes permanent deformation during long-term use or during transportation in poor environments, resulting in a loss of cushioning. It may no longer function as a material.

画時にインクシートと用紙の量大るとその部分の染料が
用紙にのらないというような色ぬけの印画不良を起こし
たり、この細片が機構部分にかみ込んで正常な動作をし
なくなるという問題点があった。In addition, small pieces of foamed synthetic resin are generated, and if the amount of ink sheet and paper increases during printing, this may cause print defects such as color fading in which the dye in those areas does not get on the paper. There was a problem in that small pieces could get caught in mechanical parts and prevent normal operation.

ことを目的とする。This invention was made to solve the above-mentioned problems, and the fixing function will not be lost even when used for a long time or in a poor environment, and furthermore, there will be no damage to other mechanical parts. The purpose of this invention is to obtain a fixed structure for a thermal head without

成としたものである。In the thermal head fixing structure according to the present invention, a through hole is provided in the arm of the thermal head, and a fixing bolt is inserted into the screw hole formed in the side plate of the printer device provided on the side of the arm. When this happens, the tip of the bolt is inserted into the through hole of the arm to fix the arm.

おけば繰り返し使用することができる。[Function J] The fixing bolt in this invention is inserted into the tip of the bolt or into a through hole formed in the arm of the thermal head and screwed to the side plate, so it can withstand strong shocks and vibrations even after a long period of time and during transportation. It can be fixed reliably even if water is added to it, and it can prevent any negative effects on the thermal or electrical field.Furthermore, this fixing bolt can be stored and used repeatedly.

15a) is a bolt for fixing, 15a) is a rod-shaped part with no thread formed at the tip, and (6) is a screw hole formed in a position opposite to the through hole (1c) of the side plate (4), which is used for fixing. When the bolt (5) for
a) is inserted into the through hole (IC) to fix rotation of the arm (1b).
