Tots are arranged perpendicularly to the feeding direction. A printer that prints alphanumeric characters, kanji, katakana, etc., uses a dot-type printer in which the dots are lined up in a vertical line in the same direction as the paper feed direction. In addition, dot matrix type heads, seven segment type heads, etc. are used for tuturers.

なければならない用途の場合には不都合が生じる。Printers that use thermal heads have many advantages, but the only drawback is that the printing speed is somewhat slow.The printing speed of printers that use electrostatic recording, inkjet, etc. is in μS. However, in the case of a thermal head, the unit is m8. This is inconvenient when it is necessary to print as much information as possible on a unit time of 11 yen, such as a facsimile machine.
本発明はこれらの欠点を改善し、印字速度を大幅に高め
たものである。以下に本発明の詳細を述べる。The present invention improves these drawbacks and significantly increases printing speed. The details of the present invention will be described below.

ードを大幅に同上させたものである。以下に本発明を実
施例について説明する。The reason why the printing speed is slow in conventional thermal printers is that the thermal energy from the heat-generating part of the thermal head is used to color the thermal paper. The time constant of the heat capacity is the cause of slowing down the printing speed.The present invention converts the heat energy consumed for purposes other than printing into another type of heat. The present invention will be described below with reference to embodiments.
第5図は本発明の一実施例を説明する図である。FIG. 5 is a diagram illustrating an embodiment of the present invention.
基本構造は先に説明した縦一列ドツト型ヘッドと同一で
あるが、横一列ドツト型ヘッドでも同様な構造が可能で

される。Although the basic structure is the same as the vertically single dot type head described above, a similar structure is possible with a horizontally single dot type head, and the present invention is applicable not only to thin film type heads but also to thick film type heads.

が肖れる。A heating section 5 for printing is formed on the insulating substrate 6-b. Another preheating heating section 26 is formed at the front in the direction of movement of the head. The heating section 26 is provided with an electrode 27 for supplying current independently of the heating section 25.As shown by the dotted line in the figure, both the heating section 25 and the heating section 26 are connected to the partial glaze layer 4. If it is formed in the soil, you can see the quality of the print.

FIG. 26 shows an example of a structure in which the heating section of the dots is heated only in front of the heating section.A heating section 30 for printing is provided on an insulating substrate 29. A dot-shaped preheating heat generating section 31 is provided in front of the head in the moving direction so as to correspond to the printing heat generating section 30. The heat generating part 31 is provided with an ilt 32 for independently generating heat. If both the heat generating part 301 and the heat generating part 3J are formed on the partial glaze layer 33 as shown by dotted lines in the figure, the printing quality will be very poor.
