PURPOSE: To prevent the generation of the ruck on an ink sheet by a simple means, by installing two guide rollers which are tilted in the vertical and horizontal directions according to the change of the tension of the ink sheet.

CONSTITUTION: When an ink sheet 1 is sent to the recording part between the recording head 3 and the platen 4, two guide rollers 10, 11 are arranged between the roll 5 and the recording part and one guide roller 10 in the vertical direction and the other guide roller 11 in the horizontal direction are respectively made to be able to be tilted. In the conveyor thus constructed, one end on the large tension loaded side of the guide roller 10 according to the tension of the ink sheet 1 is pushed down and tilted. Therefore, respective conveying passages of the ink sheet 1 upwards and downwards become almost uniform, the tension loaded on the ink sheet 1 in conveying becoming uniform and the generation of ruck is effectively prevented.
