Note that the film 2 in the film transport device 3 of FIGS. 10A to 10E is wound around the platen roller 6 in the state of FIG. 10C along the same path as that of FIG. 8C.
- FIGS. 10A to 10E show the operations of the platen roller 6, the pinch roller 22, and the guide roller 9 during printing.
- the operations of the platen roller 6 and the pinch roller 22 are the same as the operations of the film transport device 3 in FIGS. 7A to 7E.
- the operation of transporting the film 2 by the take-up side door 10 performed before the start of printing is the same as the operation of the film transport device 3 in FIGS. 8A to 8E.
- the platen roller 6 rotates in the direction of arrow B to match the printing start position of the first printing range with the printing position 14.
- the guide roller 9 moves in the direction of arrow E on the line GL with the rotation of the platen roller 6.
- the guide roller 9 When printing is started, the guide roller 9 starts moving at a predetermined speed in the direction of arrow D with the rotation of the platen roller 6 in the direction of arrow A. Thereafter, during printing, the guide roller 9 moves in the direction of arrow D in the order shown in FIGS. 10B, 10C, 10D, and 10E. After printing, the guide roller 9 is fixed at the position shown in FIG. 10C, and the next printing range is conveyed onto the outer periphery of the platen roller 6 by the take-up roller 10. When printing multiple times on the same print area, change the state from Fig. 10E to Fig. 10A after the first print on the first print area. And print again in the same print range. By providing the guide rollers 9 so as to be movable on the line GL in this manner, the contact between the films 2 during printing can be prevented.
- the guide roller 9 and the pinch roller 22 function as a slip prevention mechanism.
- the transport mechanism of the film transport device 3 shown in FIGS. 3A-B to 10A-E is not limited to transporting the film 2.
- these mechanisms including a shift prevention mechanism may be applied to the transfer material transport device 16 that transports the intermediate transfer material 15. In this case, by bringing the intermediate transfer material 15 and the platen roller 6 into close contact with each other, it is possible to prevent a shift in printing on the intermediate transfer material 15.
- each parameter may be set so as to satisfy the following expression (2).
- the contact angle ⁇ may be set to be larger than 150 ° in order to increase the frictional force between the intermediate transfer material 15 and the platen roller 6. Also, the contact between the intermediate transfer material 15 and the platen roller 6
- the diameter of the platen roller 6 may be larger than 100 mm. If the pinch roller 22 is not provided, each parameter is set so as to satisfy the following equation (2 '). I 2 T T T sin (0 T Z2) I> ⁇ ⁇ ⁇ (1 + ⁇ ⁇ )
- the rotation direction of the rotary ink ribbon unit is not limited to one direction.
- the rotary ink ribbon unit and the thermal head do not need to be provided only on one side with respect to a printing material such as a plastic film or an intermediate transfer material.
- a rotary ink ribbon unit and a thermal head may be provided on both sides of the printing medium.
