行なうのに不都合となる。Technical background of the invention and its problems As shown in Figure 1, the dot printer head 1
The carrier 2 holding the is normally held on both sides by two shafts 3 and 4. The carrier 2 has concave protrusions depending on the shape of the dot printer head 1, and therefore has a complicated shape, requires considerable strength, and is large in size. Furthermore, due to the increased weight, it becomes necessary to reinforce the thickness of the shafts 3 and 4 and the bearing structure.Furthermore, as the weight increases, the inertia of the carrier increases, making it inconvenient for sudden starts and stops at high speeds.

A platen 5 and two shafts 6 and 7 are installed in parallel on a pair of left and right frames (not shown). 8 is the head body. The head main body 8 is formed by connecting a housing 10 having a cover 9 which can be opened and closed with a guide frame 11 with screws 12, but the housing 10 and the guide frame 11 may be formed integrally. A plurality of electromagnets (not shown) are accommodated in the housing 10, and a needle (not shown) driven by the electromagnets is slidably held in the guide frame 11.

係止部２１が一体的に形成されている。 A U-shaped bearing portion 13 that is slidably fitted onto the shaft 7 is integrally formed on the cover 9. A plurality of heat dissipation fins 14 and a mounting piece 16 to the bearing member 15 are integrally formed on the housing 10, and the mounting piece 16 has a positioning fin 14 fitted to a pin 17 protruding from the bearing member 15. A mounting hole 20 that is mounted to the bearing member 15 by the hole 18 and the screw 19 is formed. The bearing member 15 has a U center around the shaft 6.
It is formed in the shape of a letter-shaped block. Furthermore, a locking portion 21 for securing a wire (not shown) driven by a motor (not shown) is integrally formed on the bearing member 15.

る。 In such a configuration, as shown in FIG. 3, the head body 8 is tilted and moved in the direction of arrow A to fit the bearing portion 13 to the shaft 7, and then the shaft 7
The head body 8 is rotated in the direction of arrow B using the pin 17 as a fulcrum, and the pin 17 and the hole 18 are engaged to position the head body 8.
The screw 19 inserted into the mounting hole 20 is screwed into the bearing member 15. As a result, the head main body 8 is held.

こともできる。 During printing, the bearing member 15 is pulled and moved by a wire connected to a motor, but since the head body 8 is directly held by one shaft 7 with the bearing part 13, a part of the head body 8 is supported. The bearing member 15 is extremely small and has high rigidity. On the other hand, the head body 8 has sufficient rigidity to protect and fix the internal electromagnet and yoke, and the reinforcement is further promoted by the fins 14, and the bearing part 13 is also a small block-shaped part in the center of the cover 9. High rigidity as it is integrally formed. Therefore, the strength is sufficient to move the head body 8. Therefore, the carrier can be omitted and the structure can be simplified, making it possible to reduce the size and weight. This reduces the inertia of the head body 8 and the bearing member 15, making it suitable for high-speed printing.
It is also possible to reduce costs by omitting a large carrier.
