があった。[Problems to be Solved] In the conventional dot print head described above, the guide hole 6 of the guide plate 10 through which the dot wire is inserted and guided is
is circular and small in diameter, and the pitch between each guide hole 6 is small, making it impossible to increase the hole diameter.As a result, when inserting the dot wire into the guide hole 6 and assembling it, the work is difficult and time consuming. There were problems such as the need for skill.
そこで、アセンブリ化が容易に、しかも時間、熟練を要
せずになし得るようにする必要があった。Therefore, there was a need for a device that could be easily assembled without requiring time or skill.

径となる異形楕円状に形成されている。1 to 3 are diagrams showing one embodiment of the present invention. 2 in FIG. 0 is a dot wire, and this dot wire 2 is attached to an armature 1 so that the armature 1 moves in the direction of the arrow in FIG. 1. It has become. Further, the dot wire 2 is inserted and guided into a plurality of guide holes 11a and flb formed in the guide plates 3a and 3b, respectively. The guide holes 11a and llb are arranged radially on the guide plates 3a and 3b, and each guide hole 1
1a and flb are formed in irregular elliptical shapes with a small diameter on the center side and a large diameter on the outside in the radial direction.

。The dot wire 2 can be easily inserted by inserting the dot wire 2 from the outer large diameter portion of each guide hole 11a, llb. Further, the dot wire 2 is connected to the guide holes 11a, l.
Since printing is performed while being pressed against the center of the lb guide plate, it does not function as a wire guide.

When passing the dot wire through the guide hole, the large diameter side of the irregularly shaped elliptical guide hole can be used to easily pass the dot wire through the guide hole, so even beginners can pass the dot wire through the guide hole in an extremely short time. This method has the advantage that there are fewer cases where the dot wire is broken due to the printing process, a dot print head with stable quality can be provided at a low price, and it is easy to automate.
