度を得ることに難点があつた。 A conventional thermal printing head has a plurality of heating elements arranged on the surface of an insulating base in a row direction at a predetermined interval from each other, and the row direction is aligned with the printing paper feeding direction. Some printers perform thermal printing by being scan-driven in the column direction, that is, in a direction perpendicular to the printing paper feeding direction. Such a thermal printing head can record dot-shaped characters, figures, and symbols on printing paper by appropriately controlling the timing of applying current to each heating element according to the scanning position of the thermal printing head with respect to the printing paper. It's becoming like that. However, the spacing between the dots constituting the characters, figures, and symbols recorded by this thermal printing head cannot be made equal to or less than the predetermined spacing between the heating elements, and this poses a problem in obtaining high printing pattern accuracy.
本考案は、高密度で、しかも高精度な印字パタ

The thermal printing head 1 of this embodiment will be described as being applied to a thin film type. This thermal printing head 1 has a plurality of heating elements 3a to 3a' arranged on the surface of an insulating base 2 made of alumina or the like, each arranged in a column direction (in the direction of arrows A and A'), and furthermore, in the overall arrangement. They are arranged in a V-shape and are driven to scan in a direction perpendicular to the printing paper feeding direction (in the direction of arrow B). Each heating element 3a to 3a' is
It is formed on the glaze layer 4, and electrodes 5, 5 as current paths are formed on the periphery thereof. 6 is a protective layer, and 7 is a passage for mutually insulating each heating element 3a to 3a'.

のである。 The heating elements 3a to 3a' each have a rectangular projection plane and are arranged with the long sides of the rectangle facing each other. For example, as a resistance material for the heating element in the case of a thin film type thermal printing head,
When using Ta 2 N, the heating element must be very thin to obtain a high resistance value. On the other hand, when the heating element is made thinner, oxidation of the heating element surface progresses as heat is generated.
As a result, the life characteristics of the heating element may be impaired. However, if each heating element is made into a rectangular shape as in this embodiment, a high resistance value can be obtained without making the heating element too thin. As a result,
The life characteristics of the heating element can be improved. Furthermore, by increasing the thickness of the heating element, the thickness can be more easily controlled during manufacturing. As shown in FIG. 1, the arrangement direction of each heating element 3a to 3a' is diagonal to the printing paper feeding direction (direction perpendicular to the direction of arrow B), and in this embodiment, the direction is 45 degrees. It is slanted. As a result, the printing pattern of characters, figures, and symbols on the printing paper by this thermal printing head 1 becomes as shown in FIG. In Fig. 4, a, b... represent each heating element 3a, 3b.
This is a printing pattern based on... As is clear from this print pattern, the print pattern can be formed into high-density pitches with no gaps between the print patterns both in the vertical and horizontal directions. In this embodiment, since the diagonal direction is set at 45 degrees, the density pitch is the same in both the vertical and horizontal directions. Further, in the embodiment shown in FIG. 4, printing is performed using only the heating elements a through.

形や記号の印字も同様に良好に行える。 Further, according to the thermal printing head of the present invention, for example, when printing the character [tree], the left hypotenuse of [tree] is the heating element a~, and the right hypotenuse is the heating element.
By printing with a'~, the direction of each oblique side matches the direction of the heating element, so a natural printing form without wobbling can be obtained, and thereby a highly accurate printing pattern can be obtained. Not only characters such as [tree] but also figures and symbols including hypotenuses in different directions can be printed equally well.

The projection plane is formed into a rectangular shape, and the long sides of the rectangle are arranged facing each other, and the direction in which the heating elements are arranged is oblique to the printing paper feeding direction.
In addition, since the overall arrangement is V-shaped, it is possible to perform high-density printing with no gaps between printing patterns, and it is also possible to print letters, figures, and symbols that include hypotenuses in different directions as well. This allows for highly accurate printing.
