【発明の詳細な説明】 （産業上の利用分野） 本発明はにドットプリンタのワイヤガイド機構に関す
る。The present invention relates to a wire guide mechanism for a dot printer.
（従来技術） ワイヤドット式のプリンタにおいては、駆動レバーの
先端に保持した多数の印字ワイヤをノズルの先端に向け
て収束させるワイヤガイド機構が必要で、これらの機構
についてはこれまでに多くの提案がなされている。(Prior Art) A wire dot printer requires a wire guide mechanism that converges a large number of printing wires held at the tip of a drive lever toward the tip of a nozzle. Many proposals have been made so far for these mechanisms. Has been done.

合を有している。Most of the proposals are to guide the row-shaped guide holes provided on the tip guide plate while curving the printing wire by a plurality of guide plates provided on the nose body. Since the guide mechanism guides the printing wire while bending it, not only an unreasonable force acts on the printing wire, but also the guide hole provided in the intermediate guide plate is worn by sliding contact with the printing wire. Have

大きな力を要するといった不都合を有している。On the other hand, the wire guide mechanism disclosed in Japanese Utility Model Laid-Open No. 57-39740 has a nose body integrally formed with
A large number of guide holes are formed in a straight line. This has the advantage that the printing wire can be guided to the nose edge without applying excessive force, but on the other hand, the printing wire can be guided over a long path. Due to the sliding contact with the hole, there is a disadvantage that a large force is required for driving.

ズ本体１の先端に臨ませるように構成されている。The tip guide plate 5 in this embodiment guides the tips of the respective printing wires 10 guided in a straight line so as to face the tip of the nose body in a line at a minute interval. On the inner surface 6 of the tip guide plate 5 facing the inside of the nose body 1, as shown in FIG. 2 (b), the openings of the guide holes 8 through which the print wires 9 pass are staggered. Also, on the outer surface 7 facing the platen 15 side, the second
As shown in FIG. 6A, the openings of the guide holes 8 are formed obliquely so as to form a line, and further, a taper 9 is formed at the inlet of each guide hole 8 on the inner surface 6 side. The print wires 10 led from one half and the other half of the bed body 1 are arranged in a zigzag pattern on the left and right guide holes 8 respectively.
Each one is alternately inserted into a and 8b so as to face the tip of the nose body 1.

を解消することができる。Moreover, the guide holes provided in the tip guide plate are formed in a zigzag shape on the inner surface side and in a linear shape on the outer surface side, and the opening edge of the guide hole on the inner surface side is tapered. Therefore, not only can each print wire taken in one half and the other half of the head be inserted into these guide holes in a well-balanced manner, but also by having these print wires along their respective tapered surfaces, Each print wire can be smoothly and accurately inserted into the corresponding guide hole without causing erroneous insertion. Furthermore, the adjacent guide holes are inclined in opposite directions, so Can be solved, and the problem that the strength of the guide hole in this portion is reduced can be solved.
