PURPOSE:To prevent an ink donor sheet from being twisted by tilting a thermal head and a back roller following the relatively large tilt of a skew preventing roller when said roller tilt is produced as a result of the ink donor sheet relatively large skewed. CONSTITUTION:An ink donor sheet 2 delivered from a supply roll 1 is, after passing through a skew preventing roller 3, through between a thermal head 4 and a back roller 5, and through between a drive roller 6 and a pinch roller 7, wound around a winding roll 8. Recording paper 9 in a state put on an ink donor sheet 2 passes through the thermal head 4 and the back roller 5. In addition, the recording paper, after any picture image was recorded thereon, is carried in the B direction. In this instance, a base 21 of a thermal head 4 is rockably mounted on a supporting plate 23 via a shaft 22, and a back roller 5 is integrally mounted on said base 21 via a supporting plate 24. Hereby, the thermal head member 4 and the back roller 5 are allowed to follow the tilt of the skew preventing roller 3 to prevent the sheet 2 between the roller 3, 5 from being twisted. |
