〈産業上の利用分野〉
本発明は、ドツトプリンタ用ドツトワイヤに関し、特に
機械的強度の高いドツトプリンタ用ドツトワイヤの端部
構造に関する。DETAILED DESCRIPTION OF THE INVENTION <Field of Industrial Application> The present invention relates to a dot wire for a dot printer, and particularly to an end structure of a dot wire for a dot printer with high mechanical strength.

ヤの折損が多いなどの問題があった。<Prior art> Generally, wires used for dot wires for dot printers include tungsten wires with an outer diameter of 0.4 or less, carbide 9
Alloy wire, piano wire, stainless steel wire, high-speed tool steel wire, etc. are used, and these wires are incorporated into the dot printer with one end supported by a holder or the like. For example, in a so-called flying type dot printer, printing is done by driving a wire by means of pushing or pulling back the holder, so not only does the holder easily fall off, but also a wire with high hardness is used. Therefore, there was a problem that the wire often broke near the holder portion where stress concentration was relatively large.
そこで、ワイヤをホルダにより確実に支持するために、
例えばワイヤの一端を折曲げ加工し、その折曲げ部分を

性による折損を生じ易いばかりでなく、形状も不安定と
なり易い。Therefore, in order to support the wire more reliably with the holder,
For example, it would be a good idea to bend one end of the wire and mold the bent part into a resin mold to form a holder, but in this case, the relatively hard wire is bent, so the wire may break during the process. There are many things. In addition, one end of the wire is made of the same or different metal material as the wire, such as Ni-
It is also possible to integrally form a spherical body by melting and cooling the Cr powder, but in this case, the wire is also heated when forming the spherical body, which changes the internal structure of the wire and prevents it from breaking due to brittleness. Not only is this easy to occur, but the shape is also likely to become unstable.

、線材を捲回する工程、及び線材などの部品点数の増加
により製造工程が煩雑化する虞れがある。Furthermore, in order to deal with the above-mentioned drawbacks, a wire material such as a phosphor bronze wire is wound two to three times around one end of the wire, and a spherical body is formed around the wound part using a hard brazing material, and the wire is placed inside the holder. Japanese Patent Application No. 59-218868 discloses that the strength of the bond between the wire and the holder can be increased by embedding the wire in the holder without heating it at a temperature that would make the wire brittle. There is a risk that the manufacturing process will become complicated due to an increase in the number of parts such as wires and wire rods.

A dot printer comprising at least one spherical body solidified to surround the outer periphery of one end of the wire, and a synthetic resin member in which the spherical body and the same end of the wire are embedded. This is achieved by providing an end structure for the dot wire.

Since it is possible to prevent the wire from falling off the holder without causing any damage, it is possible to achieve an end structure of the dot wire for a dot printer that has high mechanical strength and does not complicate the manufacturing process.
