きる。The reason for this will be explained using FIG. 3. As shown in the figure, the platen 5 is not pressed by the recording head 6 and is rotating clockwise in the figure. For this reason, the nip of the platen 5 is small on the downstream side with respect to the traveling direction of the recording paper, and becomes large on the opposite upstream side, as shown by the solid line in the figure. When the pressing force is 00, the deviation amount of the heating line 9 from the tangent line 20 of the recording head 6 and the platen 5 in the recording paper traveling direction is p1.If the deviation amount in the opposite direction is q, then the maximum value of the printing ability deviation pmaX ,
The relationship of qmax is T;)wax<qmax. That is, the margin of deviation of the heating line 9 from the tangent between the recording head 6 and the platen 5 is pmmx in the recording paper advancing direction and qIlaX in the opposite direction, where pmaX < qm
It is ax. Therefore, by setting r=~Qmax-f'max, the margin of deviation can be made equal to 9m*x''Qma- in both the recording paper advancing direction and the reverse direction.

7 mm can be taken. This is the maximum error of 0.6 when the recording head 6 and holding plate 10 are installed without adjustment.

Printing will not become impossible even if installed without adjustment.

It is possible. Furthermore, microscopically, these recording means are not necessarily arranged in a straight line, but may be arranged in a grid pattern, for example. Further, the platen is not limited to a roller as shown in the embodiment, but may be a belt-shaped platen suspended on a pulley. Furthermore, the recording material is not limited to paper, but also includes, for example, plastic sheets.

が図れる。As is clear from the above description, according to the present invention, in the above-described recording apparatus, the recording head is attached to the holding plate so that the recording line is located upstream in the recording material traveling direction from the tangent between the recording head and the platen. The structure is simple, and installation of the recording head and holding plate requires no adjustment. This improves productivity and reduces costs. Furthermore, since the torque of the platen drive motor can be reduced, costs and power consumption can be reduced, as well as noise and heat generation.
