Next, the operation of this embodiment will be described. In the image recording apparatus 10 having the above configuration, after the photosensitive material magazine 14 is set, the photosensitive material 16 accommodated in the photosensitive material magazine 14 is pulled out by the nip roller 18 and the cutter 2
After being cut into predetermined dimensions by 0, the conveying rollers 19,
It is transported by the transport rollers 21.

That is, when the photosensitive material 16 is pulled out, a motor (not shown) is rotated to rotate the nip roller 18.
Is rotated, the photosensitive material 16 is pulled out of the photosensitive material magazine 14 at a speed of 50 mm / sec.

The transport rollers 19 and 21 are also rotated by a motor (not shown) in parallel with the rotation of the nip roller 18. Thus, the photosensitive material 16 pulled out by the nip roller 18 is further transported by the transport roller 19 and the transport roller 21 at a transport speed of 50 mm / sec.

Next, when the photosensitive material 16 is pulled out by a predetermined length, the motor 418 is rotated in the forward direction and the gear 414 is rotated.
Is transmitted through the gear 412, that is, the shaft 41.
0 rotates in the direction of arrow A. Here, the one-way clutch 408 provided on the shaft 410 can transmit only the rotational force of the shaft 410 in the direction of arrow A (that is, the forward rotation of the motor 412) to the gear 406. The rotating cam 300 is transmitted to the rotating cam 300 via 402, 400, and 308, and is rotated in the direction of the arrow J in FIGS. 1 and 4 (the direction opposite to the clockwise direction) (see FIGS. 1 and 4). Since the one-way clutch 420 provided on the shaft 410 does not transmit the rotational force of the shaft 410 in the direction of arrow B to the gear 422, the pump 426 is not driven during normal rotation of the motor 412.

The operation of the drive system will be described with reference to FIG. 1 and FIGS. First, in the initial state, the rotating cam 30
0 indicates that the shutter 490 corresponds to the first optical sensor 492 as shown in FIG. When the motor 418 is rotated in the forward direction, the rotating cam 300 is rotated in the direction of arrow J from here, and the shutter 490 is moved to the second optical sensor 4.
It is rotated to a position corresponding to 94 (a position rotated 110 ° from the initial state, see FIG. 5) and temporarily stopped. Here, first, the small roller 458 is guided in the first groove portion 460A of the cam groove 460 and moves in a direction away from the rotation center of the rotating cam 300 (rotation angle of the rotating cam 300 from 10 ° to 1 °).
07 °, see FIG. 7), whereby the link 472 rotates in the direction of the arrow K, the moving blade support plate 478 also rotates in the direction of the arrow H, and the moving blade 20B of the cutter 20 moves to the fixed blade 20.
The photosensitive material 16 is cut into a predetermined length by meshing with A.
In addition, the small roller 436 abutting on the cam curved surface 438 of the cam portion 306 is guided by the fourth curved surface 438D to rotate the rotating cam 3.
00 (in FIG. 7, after the rotation angle of the rotary cam 300 is 47 °, see FIG. 7), the link 432 is in the direction of the arrow F, the link 437 is in the direction of the arrow E, and the lever 444.
Is rotated in the direction of arrow D, the roller portion 110B moves toward the roller portion 110A, and the image receiving material 108 is
B and the roller portion 110A.

Thereafter, the rotary cam 300 is further rotated in the direction of arrow J, and temporarily stops at a position 200 ° from the initial state. Here, the sector gear 304 meshes with the gear 488 at an angle of the rotation cam 300 of 115 ° to 195 °, and the gear 486 meshing with the gear 488, that is, the nip roller 18 rotates in the direction opposite to the direction of the arrow I, and Material 1
6 is returned to the photosensitive material magazine 14 by a predetermined length. For this reason, the dimension of the photosensitive material 16 protruding from the photosensitive material magazine 14 is reduced, and the photosensitive material 16 is not caught by the opening 17A of the frame 17 when the photosensitive material magazine 14 is pulled out. Note that when the photosensitive material magazine 14 is taken out, the roller portion 18B is manually separated from the roller 18A and the nip of the photosensitive material 16 is released. Also,
The small roller 474 is guided by the third groove 460C of the cam groove 460 and moves to the rotation center side of the rotary cam 300 (up to a rotation angle of the rotary cam 300 of 160 °, see FIG. 7), and supports the link 472 and the movable blade. The plate 478 is rotated and the cutter 20 is rotated.
Move blade 20B is separated from fixed blade 20A.

The photosensitive material 16 after being pulled out by the nip roller 18 and cut to a predetermined size by the cutter 20.
At a speed different from the transport speed at the time of withdrawal (11 mm /
transport roller 19, transport roller 21
Transport rollers 23, 24, 26
Is transferred to the exposure unit 22 and passes through the exposure unit 22 at a predetermined speed (for example, 11 mm / sec). At the same time as the photosensitive material 16 is conveyed (passing through the exposure unit 22), the exposure device 3
8 is operated, and the photosensitive material 16 located at the exposure section 22 is scanned and exposed. After the exposure is started, after the exposed photosensitive material 16 is once sent to the switchback unit 40,
It is fed into the water application section 62 by the reverse rotation of the transport roller 26.

In the water application section 62, the conveyed photosensitive material 1
6 is sent between the guide plate 70 and the application tank 64 by the drive of the supply roller 66, and further nipped and conveyed by the squeeze roller 68. Here, the photosensitive material 16
Is passed through the water application section 62 while the squeeze roller 68 removes excess water. The photosensitive material 16 to which water as an image forming solvent has been applied in the water application unit 62 is sent to the thermal development transfer unit 104 by the squeeze roller 68.

On the other hand, as the scanning exposure of the photosensitive material 16 is started, the image receiving material 108 is pulled out from the material receiving magazine 106 by a predetermined size by the nip roller 110 and conveyed, and further, the motor 418 starts rotating forward. The rotating cam 300 is further rotated in the direction of the arrow J, and 31 from the initial state.
It is rotated to the position of 0 ° and temporarily stops. Here, the small roller 458 of the link 456 is guided by the second groove 460B and moves outward in the radial direction of the rotary cam 300 (rotation angle of the rotary cam 300: 210 ° to 307 °, FIGS. 6 and 7).
This causes the link 456 to rotate in the direction of arrow L, and furthermore, the movable blade support plate 464 to rotate in the direction of arrow G, causing the movable blade 112B of the cutter 112 to move downward and mesh with the fixed blade 112A to cause the image receiving material to rotate. 108 is cut to a predetermined length.

Thereafter, the nip roller 110 is rotated in the reverse direction by a motor (not shown), and the image receiving material 108 nipped by the nip roller 110 is rewound by a predetermined size to the receiving magazine 106 side. Further, the rotating cam 300 is further rotated in the arrow J direction, and the shutter 490 is moved to the first optical sensor 4.
It is rotated to a position corresponding to 92 (a position rotated 360 °, that is, a position in an initial state) and stopped. Here, the small roller 436 in contact with the cam curved surface 438 is the third curved surface 4.
The link 432 is moved in the direction opposite to the direction of arrow F, the link 437 is moved in the direction opposite to the direction of arrow E, and the lever 444 is moved in the direction of arrow D. The image receiving material 10 is rotated in the opposite direction so that the roller 110B is separated from the roller 110A.
8 is released (rotational angle of rotary cam 300: 3
After 20 °, see FIG. 7). Therefore, the image receiving material 108
Is not sandwiched between the roller unit 110B and the roller unit 110A until the next processing is performed, so that the image receiving material 108 does not have the pressing marks of the roller unit 110B and the roller unit 110A. Further, the small roller 458 is guided by the second groove 460B and moves inward in the radial direction of the rotary cam 300, and
56 rotates in the direction opposite to the direction of arrow L, and further, the movable blade support plate 464 rotates in the direction opposite to the direction of arrow G, and the movable blade 112B of the cutter 112 moves upward to move the fixed blade 1
Separated from 12A.

After the operation of the cutter 112, the conveying rollers 190, 186, and 114 are guided while the cut image receiving material 108 is guided by the guide plate 182 of the image receiving material conveying section 180.
And enters a standby state immediately before the thermal development transfer unit 104.

In the thermal development transfer section 104, when it is detected that the photosensitive material 16 has been sent between the outer periphery of the heating drum 116 and the bonding roller 120 by the squeeze roller 68, the conveyance of the image receiving material 108 is restarted. While being sent to the bonding roller 120, the heating drum 11
6 is activated. Thereby, the bonding roller 120
Photosensitive material 16 and image receiving material 108 superimposed by
Means that the heating drum 11 is sandwiched between the heating drum 116 and the
6 is transported over approximately 2/3 of the circumference (between the winding roller 134 and the winding roller 140). Further, the superposed photosensitive material 16 and image receiving material 108 are heated by a heating drum 116. When the photosensitive material 16 is heated during the nipping conveyance and the stop, the movable dye is released, and at the same time, the dye is transferred to the dye fixing layer of the image receiving material 108 to obtain an image.

Thereafter, when the photosensitive material 16 and the image receiving material 108 are nipped and conveyed to reach the lower portion of the heating drum 116, the peeling claw 154 is moved by the cam 130, and the image receiving material 1 is moved.
The peeling claw 154 engages the leading end of the photosensitive material 16 that is transported a predetermined length earlier than the length of the photosensitive material 16 to peel the leading end of the photosensitive material 16 from the outer periphery of the heating drum 116. Further, the pinch roller 157 presses the photosensitive material 16 by the return movement of the peeling claw 154, whereby the photosensitive material 16 is wound around the bending guide roller 142 while being pressed by the pinch roller 157, and is moved downward. The photosensitive material 16 wound around the bending guide roller 142 is further guided by the guide roller 162 while the photosensitive material discharge roller 15
8 and 160, and the drying fan 16
5 and is accumulated in the waste photosensitive material storage box 178.

On the other hand, the heating drum 1 is separated from the photosensitive material 16.
Image receiving material 108 moving while being in close contact with 16
Is sent to the peeling roller 174. When the leading end of the image receiving material 108 is nipped by the peeling roller 174 (between the heating drum 116), the peeling claw 1 is again actuated by the cam 130.
76 is moved, and the peeling claw 17 is
6 are engaged, and the image receiving material 108 is peeled off from the outer periphery of the heating drum 116.

The image receiving material 108 peeled off from the outer periphery of the heating drum 116 by the peeling claw 176 is further moved downward while being wound around the peeling roller 174, and is guided by the receiving material guide 170 while receiving the material discharging rollers 172, 1.
The sheet is conveyed by 73 and 175, and is discharged to the tray 177 while being dried by the drum fan 168 and the ceramic heater 210 at this time.

In the case of performing image recording processing for a plurality of sheets, the above steps are sequentially and sequentially performed.

When supplying water from the replenishment tank to the application tank 64, the motor 418 is rotated in the reverse direction. Thus, the rotational force of the motor 418 is transmitted via the gear 414, and the gear 412, that is, the shaft 410 rotates in the direction of arrow B. Here, the one-way clutch 420 provided on the shaft 410 transmits only the rotational force of the shaft 410 in the direction of arrow B (that is, the rotational force when the motor 418 rotates in the reverse direction) to the gear 422.
