いられるワイヤドツト式印字ヘッドに関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a wire dot type print head that is widely used as an input/output device in information processing devices.

が行なえる。Conventionally, this type of wire dot type print head has a magnet 1, a magnet plate 2, a core 3, a coil 4, a ring 5, a gap spacer 6, a spring 7, an armature 8, a printing wire 9, and a yoke, as shown in FIG. 10
, wire guide frame 11. It is configured by arranging screws 12, cable covers 13, cables 14, etc. Here, the magnet 1 has a cylindrical shape that is magnetized in the height direction, and the magnetic flux generated from this magnet creates a magnetic attraction force between the core 3 and the armature 8, and the armature 78 is attracted to the core 3. At this time, the thin plate-shaped spring 7 is bent. When the coil 4 is energized to cancel the magnetic attraction force of the magnet 1, the magnetic attraction force between the core 3 and the armature 8 is released, so the spring 7 moves in the direction of the arrow X to return to its original state. This causes the printing wire 9 to strike the recording medium. When the coil 4 is de-energized, the 8-piece armature core 3 is imprinted. By repeating this operation, a predetermined character symbol can be printed by impact.

In this figure, white circles 93 to 9g indicate the arrangement of the tips of the seven printing wires 9, and black circles 9a'

な文字形成を阻害することになる。A solid line a-b connecting the rear end of each printing wire 1 and the center of A3 indicates the center line of operation of the armature 8 that holds the rear end of the printing wire. The tips of the seven printing wires 9 are converged by a wire guide and arranged in a straight line, and the rear ends of these wires are arranged in two rows in a staggered manner. Therefore, the tip positions of the seven printing wires 9 are 91 to 9g, while the rear end positions of the wires are 9a' to 9g.
1 will be arranged with a distance XQ in the left and right direction. As a result, the printing wire rear end positions 9al to 9g' coincide with the operating center line of each armature 8, but the wire tip positions 93 to 9g and the armature operating center line are different from those other than position 9d'. Placing the printing wires 9 with a deviation angle impairs the effective transmission of the printing energy provided by the armature 8 and the spring 7 to the printing wires 9, and also prevents the seven printing wires 9 from mutually impacting printing. The force becomes uneven, which hinders the formation of high-quality characters.

ある。The purpose of the present invention is to arrange the leading and trailing ends of the printing wires so that they are aligned with the center line in the operating direction of the armature, and to make the distance between both ends of all the printing wires uniform. To provide a wire dot type print head which can print characters of high quality by providing uniform printing energy and uniform impact printing force.

にできる。FIG. 3 shows an embodiment of the wire dot type print head according to the present invention, and schematically shows the arrangement relationship of the armature and the print wire. Note that the print head constituent members are basically the same as those shown in FIG. - The white circles 19a to 19g arranged in a straight line indicate the state of arrangement of the tips of the printing wire 9, and the black circles 19a' to 19g arranged in a circular shape indicate the tip arrangement state of the printing wire 9.
9g1 shows the arrangement of the rear ends of the printing wires 9, respectively. Furthermore, symbols a'' to g1 are the operation center lines of each armature 8, and tips 19a to 19a of the seven printing wires 9.
19g and rear ends 19a1 to 19g' are arranged to coincide with the operating center line of the corresponding armature 8, respectively. Such a power distribution configuration can also make the bend height radius of the seven printing wires 90 passing through the wire guide frame and the wire guide uniform, thereby making the percussion printing force of each printing wire more uniform.

。As explained above, according to the present invention, since printing energy is applied efficiently and uniformly to a plurality of printing wires, the quality of characters, symbols, etc. printed by impact printing by aggregation of dots can be improved. Furthermore, according to the present invention, by arranging the printing wire on the center line in the direction of movement of the armature, it is possible to avoid applying a load that may cause damage to the springs that hold the armature and the printing wire that strikes the recording medium. This enables long-term, highly reliable use.
