う問題点があった。[Prior Art] As a conventional art, the wire 12 and the lever 11 are connected to a jig 15.
There was a method of mechanically holding the wire and lever position using 14, positioning and brazing. (Figure 5) [Problems to be Solved by the Invention] In conventional manufacturing methods, the wire and lever are held in their respective positions using a jig or the like, and the wire is positioned so that it contacts the end surface of the lever. Because of this, the wire may not make complete contact with the end surface of the lever, or the wire and lever position may move when spraying brazing material. For this reason, after the wire and lever are brazed, the position of the wire and the lever may be misaligned, or the brazing material may enter between the contact surfaces of the wire and the lever, resulting in poor print quality and the wire and lever being brazed.
There was a problem in that the peel strength of the brazed portion of the steel was reduced and the durability was also reduced.

レバー１の焼なましを防止できる。Next, the operation of the positioning mechanism configured as described above will be explained. By bringing the permanent magnet 3 into contact with the positioning rigid plate 4, 1. The lever 1 is attracted to and comes into contact with the positioning plate 4 by the magnetic force of the permanent magnet 3. Also, due to this action, since the lever 1 itself has a magnetic force, the wire 2 can be brought into suction contact with the end surface 6 of the lever, and the wire 2 can be positioned at the center of the entire surface of the end surface 6 of the lever in the lever thickness direction. In addition, by using materials such as non-magnetic and good thermal conductivity for the positioning rigid plate 4 and the mating rigid plate 5, the permanent magnet 5 can be
When separated from the positioning rigid plate 4, the lever 1 can be easily removed, and the heat during brazing by a light beam, high frequency, etc. is conducted to the positioning rigid plate 4 and the mating rigid plate 5.
Annealing of lever 1 can be prevented.

きる。In this embodiment, the lever 1 is provided with a magnetic force so that the wire 2 can be brought into attraction contact with the find of the lever for positioning. This is because the lever 1 can be indirectly given magnetic force by the magnetic force of the permanent magnet 3 through the positioning rigid plate 4.
As a result, the wire 2 can be positioned in full contact with the end surface 6 of the lever, thereby preventing deterioration of printing quality due to misalignment between the lever 1 and the wire 2, and preventing intrusion of brazing material between the lever 1 and the wire 20 and peeling. It is possible to prevent a decrease in durability due to a decrease in strength.
