熱型の熱転写フィルムを用いた階調表限可能な通電熱転
写型印写装置の記録ヘッドに関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a recording head, and more specifically to a recording head of an electrically conductive thermal transfer type printing device that uses an electrically heated thermal transfer film and is capable of limiting the gradation range. Regarding.

とるにしても基板の形成は困難なプロセスであった。However, in the above-mentioned conventional technology, in order to suppress crosstalk between the recording electrodes and eliminate variations in the size of printed dots due to the recording electrodes, the thickness of the electrode substrate must be set to a value close to that of the recording electrodes, and the thickness must be uniform. It needed to be thick. For this purpose, it was necessary to pay attention to various conditions such as the method of forming the electrode substrate before sintering, the composition of the binder for sintering, the sintering temperature, and the sintering time. Further, when the substrate is formed by performing post-baking machining, the number of manufacturing steps increases, and no matter which method is used, forming the substrate is a difficult process.

ことを特徴とする。The recording head of the present invention is capable of performing a plurality of recordings [a recording head having a pole and a common electrode is pressed against a resistive layer of a sheet having a resistive layer and a heat-melting ink layer, and a current is applied to dissolve the heat-melting ink at 1 AI. In a printing device that transfers images onto recording paper, the recording head has a four-layer structure consisting of a common electrode, a spacer, a recording electrode, and an electrode substrate, and the material of the spacer is a high-density material such as polyimide whose thickness is close to the pitch of the recording electrodes. It is characterized by being a heat-resistant resin.

えた、高稍度な記録ヘッドを簡単に作ることができる。According to the configuration of the present invention, the distance between the recording electrode and the common electrode with respect to crosstalk and dot variation is determined by the thickness of the spacer and its accuracy. Therefore, the thickness of the electrode substrate and its accuracy are not a problem, so the electrode substrate can be easily formed. Then, a recording head can be formed by fixing the recording electrode and common electrode of the resulting sintered substrate to both sides of the spacer using adhesive or a head jig.
In addition, the heat-resistant resin such as polyimide used for the spacer material has high dimensional accuracy, and by making the spacer thickness close to the pitch of the recording electrodes, it is possible to create a highly robust recording head that suppresses crosstalk. It's easy to make.

電気的接触性を向上させるという効果も得られた。The suitable material for the spacer is a heat-resistant resin such as polyimide, which has excellent heat resistance and dimensional accuracy.0The recording head is subject to mechanical wear due to contact with the ink film during printing, so durability and electrical In order to improve the contact properties, the material of the recording electrode 4 is preferably a high melting point metal with excellent wear resistance such as tungsten or molybdenum, and the material of the electrode substrate 6 is a machinable ceramic mainly composed of mica. In this investigation, we used tungsten as the recording electrode material, mica ceramics as the 'FjL electrode substrate material, polyimide resin with a thickness of 150 μm as the spacer material, the recording degree was 4 dot/mu, and the number of recording electrodes was 80
When we prototyped a book recording head and conducted a printing test using 8-division motion, we found that 16-gradation expression was affected by crosstalk,
A high quality print with no dot variations was obtained by recording 'Iml'4. Furthermore, the spacer was subjected to thermal abrasion during printing, and as a result, the recording electrode was made to protrude, thereby improving electrical contact with the film.
