Reference numerals 2 and 2' indicate side plates attached to the main body housing 1, 3 indicates a metal shaft with both ends fixed to the side plates 2 and 2', and a print head 4 is attached to the metal shaft 3.
A carriage 5 with the attached thereon is slidably arranged. In addition, this metal shaft 3 has second
It is attached by press-fitting a cap 6 made of a vibration-proofing material as shown in the figure, and then press-fitting it into holes provided in the side plates 2, 2'. A small hole 6a for air release is provided at the bottom of the cap 6, and a collar 6b is provided outside the opening so as to come into contact with the side plates 2, 2'.

ことなく実施することができる。 That is, in the printing device according to the present invention, the cap 6 is press-fitted into both ends of the metal shaft 3 on which the carriage 5 is disposed, and the cap 6 is attached by being press-fitted into the side plates 2, 2'. bearings and print head 4
The vibrations at are no longer transmitted directly to the side plates 2, 2', and the noise is reduced. Furthermore, the metal shaft 3 can be fixed by simply press-fitting the cap 6 into the side plates 2, 2' with the caps 6 press-fitted to both ends. Since these can be shared, implementation can be achieved without increasing the number of parts or increasing the price.

傷も防止できるものとなる。 As described above, the present invention includes a print head attached to a carriage that is slidably disposed on a metal shaft with both ends fixed to a side plate, and a drive device that moves this print head together with the carriage on the metal shaft. , a cap made of vibration isolating material having a flange outside the opening is press-fitted into both ends fixed to the side plate of the metal shaft, and this cap is press-fitted into the hole of the side plate from the inside, so that the cap is This makes it difficult for vibrations to be transmitted to the side plate, eliminating noise. Also, since the cap has a flange outside the opening, it acts as a stopper when the cap is press-fitted into the side plate, ensuring secure fixation. Even in the event of a collision caused by running out of control or being pushed by hand, the brim acts as a buffer and prevents damage.
