産業上の利用分野
本考案は記録装置、いわゆるプリンターに関
し、特に形状記憶合金の性質を利用した記録ヘツ
ドをもつ記録装置に関するものである。[Detailed Description of the Invention] Industrial Application Field The present invention relates to a recording device, a so-called printer, and particularly to a recording device having a recording head that utilizes the properties of a shape memory alloy.

す等の欠点があつた。 Wire dot printers are conventionally widely used printers. The basic structure of this wire dot printer is as shown in FIG. 1, in which a printing wire 1 strikes an ink ribbon 2 and a paper 3 to form a dot image. Although this method can obtain stable images at relatively high speed, it has drawbacks such as high noise and dirty hands when changing the ink ribbon.
考案の目的
本考案は上記の欠点を解消し、ワイヤドツトプ
リンター程度の画質をもち、低騒音で保守性が容
易な記録装置を提供することにある。Purpose of the invention The object of the invention is to eliminate the above-mentioned drawbacks and provide a recording device that has image quality comparable to that of a wire dot printer, has low noise, and is easy to maintain.

ある。Structure of the invention The gist of the invention is that the head has shape memory alloy wires arranged in parallel through individual heat generating elements on the front surface of the head, and an ink tank holding ink. The free end side of the alloy wire is curved downward when not heated and comes into contact with the ink in the ink tank, and the ink adheres thereto, and when heated, the free end side of the alloy wire becomes straight so as to contact and transfer the attached ink to the paper. This is a recording device characterized by the following.
尚、形状記憶合金とはこの材料自身に形状を記
憶させることが可能な合金であり、外部からこの
合金の温度を調整することにより大きな変位を与
えることが出来る。 Note that a shape memory alloy is an alloy that allows the material itself to memorize its shape, and by adjusting the temperature of this alloy from the outside, it is possible to give a large displacement.
実施例
以下に本考案の実施例を図面に従つて詳述す

ことが出来る。 2 and 3 show an embodiment of the present invention, in which a heating element 5 is provided on the front surface of a horizontally positioned head 4, and the heating elements 5 extend in parallel through the heating element 5. One end of the shape memory alloy wire 6 is fixed to the head. At low temperatures, this shape memory alloy wire
The shape memory alloy is memorized so that the free end is attached to the paper 3 and the shape memory alloy is in a straight state at high temperature so that the leading end comes into contact with the paper 3. Now, when the heating element 5 generates heat according to the image information, the ink attached to the tip of the shape memory alloy wire is transferred onto the paper 3 to form an image.

In this device, the thermal head 4 is 3 dots/mm, and the shape memory alloy wire is, for example, Cu-
Uses Zn-Al based shape memory alloy wire,
This wire array 6 is arranged in parallel in the horizontal direction at an interval of 3 wires/mm. A toy-shaped ink tank 7 is arranged below the wire array along the wire array. Although the paper conveyance device is not shown, in this embodiment, the paper is conveyed in the direction of arrow A. A head facing roll 8 is also arranged parallel to the wire array.
なお、形状記憶合金には第２図の鎖線で示す様
に、非発熱時には湾曲し、発熱時には直線状態と
なるよう予め記憶させてある。 Note that, as shown by the chain line in FIG. 2, the shape memory alloy is preliminarily memorized so that it is curved when no heat is generated, and becomes straight when heat is generated.
