緒に搬送されることになる。 This type of thermal transfer recording device uses as an ink master material an ink layer formed on a film that is solid at room temperature and becomes viscous or fluid when heated, and a receptor sheet made of plain paper is placed on the side of the ink layer. The ink is selectively heated from the back side of the film using a thermal recording means such as a thermal head to melt the ink, and the ink is transferred and recorded onto the receiving sheet. In this case, it is necessary to convey the ink master material and the receiving sheet together in a predetermined direction and peel them off at the same time as recording or after recording, but this conveyance drive method is theoretically similar to that of a thermal recording device. It is possible to repurpose it. The main part configuration in that case is shown in FIG. 1. In the figure, 1 is an ink master material, 2 is a receiving sheet, 3 is a thermal head, 4 is a rubber roller, and 5 is a stripper. That is, the rubber roller 4 applies a load and a predetermined signal is sent to the thermal head 3 to perform recording, and the ink master material 1 and the receiving sheet 2 are conveyed by driving the rubber roller 4. When the rubber roller 4 is driven to convey the receiving sheet 2,
The ink master material 1 is conveyed together with the receiving sheet 2 due to friction.
ところが、インクマスタ材１は通常10〜12μｍ

生じ、このずれが次第に累積されると、第２図に
示したように薄いインクマスタ材１にはシワ６が
できてしまう。そして、このことは記録画像の画
質劣化をもたらす大きな原因となる。 However, the ink master material 1 usually has a thickness of 10 to 12 μm.
An ink layer of 4 to 8 μm is provided on a thin film of
100 μm plain paper is used. For this reason, the first
The driving method as shown in the figure has a problem in that the thin ink master material 1 is easily wrinkled. For example, consider a case where two lines along the conveyance direction are recorded. At this time, in the ink master material 1, the second
As shown by diagonal lines in the figure, the ink layer melts along the two lines, and the melted ink bonds the ink master material 1 and the receiving sheet 2, and they are fed together at the two lines. . However, if the ink layer remains solidified, the ink master material 1
The frictional force between the ink master material 1 and the thermal head 3 is small, and the frictional force between the ink master material 1 and the thermal head 3 is relatively large. If a deviation occurs in the feeding and this deviation is gradually accumulated, wrinkles 6 will be formed in the thin ink master material 1 as shown in FIG. This is a major cause of deterioration in the quality of recorded images.

This also applies to the case where it is driven by
この問題は、例えばインクマスタ材１を十分厚
くすれば解決できるはずである。しかしながら、
インクマスタ材１を厚くすることは解像度の高い
転写記録を難しくするので好ましくない。 This problem should be solved, for example, by making the ink master material 1 sufficiently thick. however,
Increasing the thickness of the ink master material 1 is not preferable because it makes transfer recording with high resolution difficult.

Either the ink master material is conveyed while being sandwiched across its entire width, and the receiving sheet is conveyed together with the ink master material by friction with the ink master material, or the conveyance driving means is transferred to the ink master material by thermal recording means. The drive roller is placed in front of the ink master material and the receiving sheet in the conveying direction, and the drive roller is in contact with the ink master material and the pinch roller is in contact with the receiving sheet. It is characterized by being conveyed and driven together by friction.
As a result, the ink master material can be conveyed with a uniform tensile force over its entire width, and wrinkles can be prevented even if the ink master material is thin.
