Is a distance measuring means for detecting the feed amount or the position of the ink sheet 1 from the number of rotations.

Further, referring to FIG.
0 and the stretched ink sheet 1 are provided so as to configure the recording paper transport path 13 at a fixed inclination angle with respect to the transport direction of the recording paper 2 (the direction of arrow C in the figure).

1 to 4, the same components as those of the conventional thermal transfer recording apparatus are denoted by the same reference numerals as in FIGS. 13 and 14, and the description is omitted.

Next, the thermal transfer recording operation in the thermal transfer recording apparatus of the present embodiment will be described. The recording paper 2 fed from the recording paper storage unit 7 by the paper feeding unit 10 is nipped by the recording paper transport rollers 8 and 9 of the recording paper transport unit 18 and guided to the recording unit 16. At this time, the ink sheet 1 is stopped at a predetermined position by detecting the position of the mark 1b by the sheet mark detection sensor 51 in advance.

Further, the recording paper 2 conveyed in the recording paper conveyance direction (the direction of arrow C) is guided by the ink surface 1a of the ink sheet 1 stretched at an angle to the conveyance direction, and The recording paper is sent to the recording paper transport path 13 constituted by the guide member 50 and the guide plate 19.

At this time, the recording surface 2a of the recording paper 2 is fed while being in contact with the ink surface 1a of the stopped ink sheet 1, and is rubbed and slid by the sheet guide member 50 via the ink sheet 1. Sent while being sent.

Therefore, foreign matters such as dust and paper dust adhering to the recording surface 2a fall off by sliding, and
