されない状態が出現する。 In drawing using a serial heating head, the heat generated by the heating element must reach the recording paper, making it difficult to speed up the drawing time.
Therefore, an attempt has been made to effectively double the drawing speed by using a two-row heating head in which the heating element rows are arranged in two rows and driving the two rows individually. FIG. 5 shows an example of a serial heating head having two rows of heating elements. Two heating element rows 4 are formed on a substrate 3, and wiring 5 and external terminals 6 are provided for generating heat from one of the heating elements in the heating element row 4, so that one heating element can be integrated into one body. If drawing can be done in a time of 100 kHz, if the heating element rows 4 are operated in parallel, it is possible to obtain twice the speed compared to the conventional heating head shown in FIG.
However, when a serial heating head having two heating element rows 4 shown in FIG. 5 is used, the quality of drawing on the side of the heating element rows that will be drawn later in the drawing state is poor. That is, at the beginning of drawing, the drawing is good, but after a while of continuous drawing, a state appears in which the points drawn by the heating element row on the side to be drawn later are not drawn.

When a generates heat, a part of the recording paper melts due to the heat, and if the following heating element part 11b does not generate heat,
A part of the melted recording paper is fixed and becomes a deposit 12. This deposit 12 covers the part of the subsequent heating element 11b that should generate heat, and then the subsequent heating element 11
Even if b generates heat, it acts as a heat insulator and does not allow the heat to reach the recording paper, resulting in poor drawing quality.

The gist of the present invention is to energize the heating elements according to drawing information while moving the first and second heating resistor rows in which a plurality of heating elements protrude from a substrate and are arranged in the vertical direction in the horizontal direction. However, in a serial heating head that records on a recording paper by melting the recording medium based on the heat generated from the heating element, the heating element is placed below the protruding height of these heating resistor rows and between them. The reason for this is that the protruding portions which do not include the heat generating resistors are provided in the shape of an embankment with a length that shields the second heat generating resistor array from the first heat generating resistor array.

Wiring is not shown to clarify the point of the invention. In the center of the two resistor rows 4, an embankment-like protrusion that does not include a heating element, that is, a barrier 13 is provided with a length that shields the two resistor rows. This barrier 13
In addition, a portion of the recording paper melted by the preceding heating element portion 11a is completely solidified and attached. However, a portion of the recording paper melted beyond this barrier 13 does not reach the subsequent heating element section 11b, and good drawing quality can be maintained in both the two rows of heating element sections 11a and 11b. The barrier 13 includes heating element portions 11a, 1
If the material is the same as the glaze layer used for 1b,
It can be easily formed without increasing the number of manufacturing steps.

著しく減らすことができる。 FIG. 9 shows another embodiment of the serial heating head having two rows of heating elements according to the present invention. The barrier 13 is not parallel to the heating element rows 11a, 11b, but is closer to the preceding heating element row 11a at the top and closer to the succeeding heating element row 11b at the bottom. By doing so, a portion of the recording paper adhering to the barrier 13 is automatically ejected, and the frequency of maintenance and inspection can be significantly reduced.

リヤー１３は、発熱体列部１１ａ，１１ｂの高さ
（基板３からの突出高さ）を超えてはならない。 Care must be taken regarding the height of the barrier 13. That is, the heat generating element array portion 11a of the heat generating head,
11b is made high by providing a glaze layer so that it can be pressed against the recording paper even with a low pressing pressure, and if this is impaired, good drawing cannot be achieved. The barrier 13 must not exceed the height of the heating element rows 11a, 11b (projection height from the substrate 3).

かつた。 A checkerboard pattern was drawn using the serial heating head having two rows of heating elements according to the present invention as described above, and the number of drawing sheets (A4 size) at which the drawing quality deteriorated was tested. As a result, in the conventional two-row heating head, the drawing quality deteriorates from the second sheet onwards, whereas in the barrier-equipped head of the present invention, an average of 27 sheets are drawn when the barrier is parallel to the row of heating elements. When the quality deteriorates and the barrier is made oblique (the angle between the leading resistor row and the barrier is 30°)
No deterioration in drawing quality was observed even after drawing 100 images.
