し易いきいう種々の欠点があった。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a dot printer. Conventional printers of this type used a printing wire to transfer dot pixels onto printing paper on a platen, which required a mechanical mechanism such as a bearing member to support the tip of the printing wire. There are various drawbacks such as the large number of members constituting the mechanism, making the device complex and large, and the contact movable parts such as the bearing member of the printing wire prone to frequent wear and damage.
この発明は上記従来のもののもつ欠点を排除するこ乏が
できるドツトプリンタを提供することを目的とする。The object of the present invention is to provide a dot printer that can eliminate the drawbacks of the conventional printers mentioned above.
この発明の実施例を添付図面を参照しながら説明する。Embodiments of the invention will be described with reference to the accompanying drawings.

0 is liquid ink, 11 is a through hole tube, 12 is a holding member, 13
each represents a power source. A printing paper 2 is attached to the surface of the platen 1, and an electrostrictive element 8 is placed at a position a predetermined distance apart from the platen 1 with the printing surface of the printing section 8' facing the electrostrictive element 8. The attached electrodes 6.6 are held and fixed at their respective rear ends by a holding member 12.
そして前記離間中は電歪素子８の歪変位にともなう印字
部８′のインノξクトによって鮮明なドツト画素を印字
紙上に転写できる程度に形成されている。During the separation, sharp dot pixels are formed to the extent that a clear dot pixel can be transferred onto the printing paper due to the ink of the printing portion 8' caused by the strain displacement of the electrostrictive element 8.
電極６を両側に取付けた電歪素子８はこの電極６に電源

浸材７よりの液体インク１０によって印字部８′は常に
湿潤されるように形成されている。When an electrostrictive element 8 with electrodes 6 attached on both sides is supplied with current from a power source 13 to the electrodes 6, the electrostrictive element 8 is distorted in the direction of the platen.
It is formed so that the printing surface of the printing section 8' impacts the printing surface of the printing paper 2. Further, the electric/strictive element 8 is slidably covered by the ink-impregnated material 7, so that printing can be performed using the liquid ink 10 from the impregnated material 7 containing the liquid ink 10 contained in the ink tank 9. The portion 8' is designed to be constantly wetted.
より詳細に説明すると、電歪素子８の印字部８′は先細

液体インク１０によつ゛Ｃ印字部８′の印字面は常に湿
潤されているものである。To explain in more detail, since the printed portion 8' of the electrostrictive element 8 is formed in a tapered shape, this tapered portion and the impregnated material 7
An ink reservoir 16 is located between the sliding holes 7' formed by the covering of the ink reservoir 16.
The liquid ink 10 accumulated in the ink reservoir 16 keeps the printing surface of the "C" printing section 8' moist at all times.
また電歪素子８の印字部８′の印字面と含浸材７の摺動
孔７′の端面とはほぼ同一平面内に位置するように形成

溜表面とは而−かまたはこれよりも引込んでいるように
維持されている。Furthermore, the printed surface of the printed portion 8' of the electrostrictive element 8 and the end surface of the sliding hole 7' of the impregnated material 7 are formed to be located on almost the same plane, so that the ink does not accumulate in the ink reservoir 16. The reservoir surface of the liquid ink is formed in a half-moon shape, and is maintained so that it is retracted from at least the printing surface of the printing section 8' of the electrostrictive element 8 and the reservoir surface of the liquid ink 0. has been done.
上述のように構成されたこの発明の作用を訝明すれば次
のとおりである。The operation of this invention configured as described above is as follows.
電歪素子８の両側面の電極６，６に電源１３からの供通
電流を通電することにより、電歪素子８には歪が生じ、
この歪変位によって電歪素子８の印字部８′は印字紙２

は液体インク】０が常に付着されているので、印字部８
′の印字面が印字紙２表面に当接するときにそのインク
が印字紙２面に転写され、印字紙２面ｌこはドツト画素
が形成される。By applying a current from the power source 13 to the electrodes 6, 6 on both sides of the electrostrictive element 8, strain is generated in the electrostrictive element 8.
Due to this strain displacement, the printing portion 8' of the electrostrictive element 8 is
Shockingly rush in the direction. At this time, since the liquid ink ]0 is always attached to the printing surface of the printing section 8', the printing section 8'
When the printed surface of ' comes into contact with the surface of the printing paper 2, the ink is transferred to the 2nd surface of the printing paper, and dot pixels are formed on the 2nd surface of the printing paper.

体が摩耗、損壊などした場合にはこのチップ１５を取換
えるだけで他の部材はその才ま使用できる利点がある。In FIG. 3, an electrostrictive element 8 is formed by attaching a chip 15 made of alloy or the like to the tip of a tapered printing part 8'.In this case, the chip 15 is used during printing, and the printed body is In the event of wear or damage, the tip 15 has the advantage of being simply replaced and the other members can be used for the time being.
なおチップ１５の材質は樹脂系、繊維系、ゴム系、セラ
ミックス系等あるいはこれ等の合成でもよい。Note that the material of the chip 15 may be resin-based, fiber-based, rubber-based, ceramic-based, etc., or a composite of these.

ドツト画素の転写を行なわせることもできる。FIG. 4 shows a structure in which a plurality of dot printers according to the present invention are arranged along the longitudinal direction of the platen 1. Although not particularly shown, an ink-impregnated material 7 covering adjacent electrostrictive elements 8 is shown in FIG. The pixel can also be impregnated with liquid inks of different colors to effect the transfer of multicolored dot pixels.
なお上記実施例においては、歪変位によつ−ご移動する
移動素子として電歪素子を説明したが、これに限定する
ものでなく、電歪素子に代えて磁歪素子を用いることが
できることは言う迄もない。In the above embodiment, the electrostrictive element was explained as a moving element that moves due to strain displacement, but the present invention is not limited to this, and it is possible to use a magnetostrictive element instead of the electrostrictive element. Not until now.
