Abstract

PURPOSE:To contrive to enhance efficiency and printing speed of a printing head, by constituting an armature of an armature base and an armature auxiliary plate formed of a high tensile strength material, fixed to the base and engaged with a wire. CONSTITUTION:The armature auxiliary plate 14 formed of a thin high tensile strength material such as spring steel is fixed to the armature base 13 consisting of 3% silicon steel by brazing, laser welding or the like to constitute the armature 12. The width of the auxiliary plate 14 is reduced toward the tip thereof, the tip is made to be an engaging part 14a for the wire 5, and both side parts are made to be reinforcing bent parts 14b. Since the weight of the base 13 made to have a required minimum size constitutes a major part of the weight of the armature 12, the moment of inertia of the armature 12 can be made to be extremely small, and it can be contrived to enhance the printing speed of the printing head.

Technical background of the invention and its problems FIG. 1 schematically shows a conventional wire-type printing head. When the coil 2 of the electromagnet 1 is excited, the armature 3 rotates around its rotation fulcrum 3a. The wire 5 is attracted to the core 4 and is fixed to the armature 3 to actuate it. As a result, the wire 5 is displaced while being guided by the guide member, collides with the printing paper 8 on the platen 7 via the ribbon 6, and printing is performed. Thereafter, due to the collision repulsion force at this time and the return force of the return spring 9, the wire 5 and the armature 3 return to their original positions regulated by the stopper 10, and enter a standby state. By repeating such operations, a predetermined print is made on the printing paper 8. 11 is a yoke.

Since the armature 3 repeatedly rotates around its rotation fulcrum 3a at a high frequency, the moment of inertia of the armature 3 must be minimized to increase the efficiency and speed of the print head. It is advantageous to do so. For this reason, conventionally, the shape of the armature 3 is as shown in FIG. 2.

That is, the area near the rotation fulcrum 3a, which is part of the magnetic circuit, has a large cross-sectional area, and the tip end, which is engaged with the wire 5, is made thin and slender within a range that does not impair strength. . The specific manufacturing method is generally to press a plate material, and the thin part at the tip is processed by machining. Therefore, the processing steps are often ``outer punching'' - ``spill processing'' - [edging process (re-punching the relief part of the meat by cutting the tip) - ``shaping''. However, during this machining, the flatness of the bottom surface is likely to be lost, making machining difficult. That is, the machining process of the armature is long, which also causes problems in component accuracy.

Furthermore, the armature 3 forms a magnetic circuit together with the core 4 and yoke 11, and 3% silicon steel is often used as the material for the core 4 and yoke 11 in order to reduce high frequency loss. 3%
If silicon steel is used to form the shape shown in Figure 2, cracks will occur during machining, making it unusable as a part. Therefore, the armature 3 is made of 1% silicon steel, which has a large high frequency loss.

It is made of silicon steel, and its dimension Q is the minimum dimension required to form a magnetic circuit with the core 4 and yoke 11, as shown in FIG. 3, by flat processing with a large cross-sectional area. On the other hand, the armature auxiliary plate 14 is made of a thin high-tensile material such as spring steel, and is fixed onto the armature base 13 by brazing, laser welding, or the like.

According to such an armature 12, most of its weight is accounted for by the armature base body 13, which has the minimum necessary dimensions, and it is possible to achieve further weight reduction compared to the armature 3 shown in FIG. It is obvious that the moment of inertia of the armature 12 can be significantly reduced and the speed of the print head can be increased. Of course, there is no problem with the operation of the magnetic circuit-forming sitting wire. In addition, the armature base 13
Since no machining is required and only punching is required, the total number of machining steps can be reduced even when machining the armature auxiliary plate 14 is taken into account, and the accuracy of the parts can also be improved. In addition, since the armature base 13 does not require shaving processing, 3% silicon steel can be used as its material, and together with the core 5 and yoke 11, which are made of 3% silicon steel, it is possible to reduce high frequency loss. A highly efficient print head can be obtained.
