It

As shown in FIG. 6A, the rotary drum 18
Is rotating in the direction of arrow A, and the heat-sensitive material 16A is wound around the rotating drum 18 with the tongue region 94 as the end end.
At this time, the image receiving sheet taking-out pawl 72 is rotating around the image receiving sheet taking-out pawl rotating shaft 72B in the direction of arrow B in FIG.
The image receiving sheet take-out pawl 72 is in a state of falling with respect to the rotary drum 18. For this reason, a gap is formed between the rotary drum 18 and the bottom portion 72F of the image receiving sheet guide claw 72, and there is no obstacle in winding the heat-sensitive material 16A on the rotary drum 18. The rotating roller 65 is rotating in the direction opposite to the arrow A direction in FIG. 4 until the thin plate-shaped metal fitting 64B contacts the rotating roller 65, and the peeling claw 64 is tilted with respect to the rotating drum 18.

The rotation is started in the direction of arrow B opposite to the direction. Further, the tension roller 61 and the transport roller 82 also start to rotate. At this time, the rotating roller 65 is rotating in the direction opposite to the arrow A direction of FIG. 4 until the thin plate-shaped metal fitting 64C comes into contact with the rotating roller 65, and a slight gap is formed between the rotating drum 18 and the peeling claw 64. It is formed (hereinafter, this state is referred to as a half-gap state). Therefore, the image receiving sheet 86 passes through the gap between the rotary drum 18 and the peeling claw 64, but
The nail tip portion 64A of the claw enters the center of the step between the image receiving sheet 86 and the color material sheet 88, and the color material sheet 88 is separated by the peeling claw 64.
It is lifted by the nail tip portion 64A. Therefore, the color material sheet 88 is separated from the image receiving sheet 86 at a constant speed according to the rotation speed of the drum 18 (see FIG. 7B). At the time of this peeling, the coloring material in the portion irradiated with the laser strongly adheres to the image receiving sheet 86, and thus the image receiving sheet 86
An image is formed on it. The peeled coloring material sheet 88 is pulled by the pulling roller 61 (see FIG. 5), and the conveying roller 8
After passing 2, the sheet is discharged to the color material sheet receiver 28. The image receiving sheet take-out claw 72 remains in a tilted state. Therefore, the image receiving sheet 86 is wound around the rotary drum 18.

As shown in FIG. 6D, the coloring material sheet 88
After being discharged to the color material sheet receiver 28, the rotary drum 18 further rotates in the direction of arrow B. At this time, the peeling claw 64 is in a state of falling from the half gap state. Further, the image receiving sheet taking-out pawl 72 is arranged around the image receiving sheet taking-out pawl rotating shaft 72B as shown in FIG.
It rotates in the direction opposite to the arrow B direction, and the claws are raised with respect to the rotary drum 18. Therefore, the image receiving sheet 86 wound around the rotating drum 18 is separated from the rotating drum 18 by the claw tip portion of the image receiving sheet take-out claw 72 with the end end as the tip. Further, the front end of the image receiving sheet 86 is guided by the endless belt 70, conveyed by the conveying rollers 75, 76 and 77, and discharged to the image receiving sheet receiver 78. The upper side of the image receiving sheet receiver 78 is open on the machine base 12 side, and the operator can take out the image receiving sheet 86 from the image generating apparatus 10.

As described above, in this embodiment, the image receiving sheet 8
Since 6 and the color material sheet 88 are adhered and simultaneously conveyed and wound around the rotary drum 18, the conveyance path can be simplified as compared with the case where the image receiving sheet 86 and the color material sheet 88 are separately conveyed.

Further, since the image receiving sheet 86 and the color material sheet 88 are conveyed as a heat-sensitive material which has been adhered in advance, dust and dust do not enter between the image receiving sheet 86 and the color material sheet 88 in the conveying path. Therefore, an image without image defects can be obtained.

Further, since the heat-sensitive material 16 is provided with a step (bello region 94) and a non-adhesive region 92 on the image receiving sheet 86 and the color material sheet 88, the image receiving sheet 86 and the color material sheet 88 can be easily peeled off. can do.

The sheet 88 can be smoothly peeled off and taken out.

Further, since the rotary drum 18 rotates at a constant speed and the peeling speed becomes constant, it is possible to obtain the image receiving sheet 86 free from the streaks and the like that occur in the case of manual peeling.

The heat-sensitive material 16 (16A) of this embodiment is used.
The image receiving sheet 86 and the color material sheet 88 are adhered with a uniform adhesive force. However, as shown in FIGS. 8A and 8B, the adhesive force around the image forming area 102 is stronger than the adhesive force. You may provide the strong adhesion area | region 102 which has. By doing so, the heat-sensitive material 16 or 16A is transferred to the image receiving sheet 86 and the color material sheet 8 while being conveyed by the automatic heat-sensitive material conveying section 14.
8 can be prevented, and a more stable image can be recorded on the image receiving sheet 86.

In this case, as shown in FIG. 8C, one end of the strong adhesion region 104 in the peeling direction may have an inverted V shape, and the non-adhesion region 106 may have a V shape accordingly. In the case of the inverted V-shape, the peeling stress generated by the peeling claw 64 is dispersed, so that the strong adhesion region 10 having a strong adhesive force is formed.
4 can be easily peeled off.

Further, as shown in FIG. 8D, one end in the peeling direction of the strong adhesion region 106 may not be entirely bonded, but only the triangular portions having a plurality of peeling directions as vertices may be bonded. By doing so, peeling can be easily performed as in the case of FIG. 8C.

Further, as shown in FIGS. 8 (E) and 8 (F), the entire surface of the strong adhesion regions 102, 104 and 108 shown in FIGS. 8 (A), 8 (B) and 8 (C) can be easily peeled off. To do this, it may be triangular or rectangular.
