02.206 rises in temperature, and when the temperature is adjusted and transfer becomes possible, a start switch is turned on to raise the positioning pin 68 (step 402).

From this state, in step 404, the motor 46 is activated to raise the positioning pin 68 together with the flat bar 38. As a result, the flat bar 38 is inserted into the rectangular opening 30A of the workbench 30, and the positioning pin 68 passes through the through hole 32A of the guide plate 32 and projects above the guide plate 32. In addition,
The swinging portion 507 of the peeling mechanism 19 is swung in advance so that the cover sheet 110 is adhered to the adhesive roller 504 and peeled off from the guide plate 32 (FIG. 2A).

Since it is not covered by the sheet 110, the conveyed sheet body 35 passes through the temporary fixing section 20.
It is inserted between the heated transfer rollers 202 and 206 of the transfer unit 22 and held therebetween. This temporary fixing roller 158 temporarily fixes the image sheet 26 and the image receiving sheet 28 . Since the temporary fixing roller 158 is formed as a skewer-shaped roller, a plurality of temporary fixing positions are provided along the conveyance direction of the conveyed sheet body 35. For this reason, the air between the temporary fixing position and the temporary fixing required position tends to escape backward in the conveying direction, and is pushed out when being conveyed between the heated transfer rollers 202 and 206 in the next step 416, so that the air does not form with the image sheet during transfer. No air bubbles are generated between the image receiving sheet and the image receiving sheet.

In this case, in step 418, the cover sheet 110 covers the conveyed sheet 60 to form the conveyed sheet body 35, and the conveyed sheet body 35' is conveyed.

The image recorded on the image sheet 26 is transferred to the image receiving sheet 28 by being pressurized and heated by being held and conveyed by the heating transfer rollers 202 and 206. The conveyed sheet 35 transferred by the transfer section 22 is sent to the receiving section 24.

When the conveyed sheet body 35 is delivered to the receiving section 24, the motor 252 is reversely rotated in step 420, and the heating rollers 202 and 206 are reversely rotated.

In this state, motor 284 is activated in step 422. Operation of the motor 284 causes the abutment pin 266.26 to
8 moves to insert the conveyed sheet 35 again between the heated transfer rollers 202 and 206.

Since the heated transfer rollers 202 and 206 are rotating in the opposite direction,
The conveyed sheet body 35 is transferred again to the heated transfer roller 20.206.
It is inserted between the temporary T-roller 158 and the roller 162 while being pinched and conveyed by the rollers 158 and 162.

In step 424, the conveyed sheet body 35 is attached to the temporary fixing portion 20.
The operation of the motor 284 is stopped at the point when it is sent out from the
The movement of the guide plate 32 is stopped.

At this time, the conveyed sheet body 35 is sent to the working section 18 a.

This completes the transfer, and the operator grasps the swinging part 507 of the peeling mechanism 19 with his/her hand and swings it to bring the adhesive roller 504 into contact with the vicinity of the feed-out end of the cover sheet 110, and then Release 507. Then, the swinging portion 507 is swung to the upright position by the weight 506, and the cover sheet 100 is peeled off to the vicinity of the end on the temporary fixing portion 20 side. After the base layer of the image sheet 26 is peeled off from the image receiving sheet 28 in this peeled state, the image receiving sheet 28 is removed from the guide 30.

Next, in step 426, the operator determines whether to return to before step 402 or terminate. When returning to before step 402, the following steps are executed.

In this way, in this embodiment, the operator can peel off the cover sheet 110 from the conveyed sheet 60 that has been transferred by simply grasping and swinging the swinging part 507 of the peeling mechanism 19, and can also peel off the cover sheet 110 from the conveyed sheet 60 that has been transferred. Since the cover sheet 110 can be automatically covered over the sheet to be conveyed 60 to be started, the handling of the cover sheet 110 is not only easy, but also the handling of the cover sheet 110 is easy. There are no problems with 110 dirt or scratches.

Further, in this embodiment, the cover sheet 110 is attached to the adhesive roller 5.
04 and is peeled off from the guide plate 32, the operator does not have to worry about the cover sheet 110 falling while working on the workbench.

In this embodiment, the brush 70 returns to the initial position while the conveyed sheet body 35 is being cooled, but it may be returned at any time after the conveyed sheet body 35 passes the temporary fishing part 20.

In addition, in this embodiment, the case where the developed image sheet 26 is superimposed on the image receiving sheet 28 and transferred is explained, but when the image receiving sheet 28 after the transfer is completed is superimposed on a transfer target sheet such as paper and paper transfer is performed. The device of the invention is also used. In this case, the positioning pin 6 of the positioning mechanism 36

Control Device> The image transfer device 1010 is also provided with a control section 1189 that controls the operation of the image transfer device 1010. Connections between this control section 1189 and each component will be explained using the block diagram shown in FIG. 19. Control unit 1189cR
It is composed of an AM 1191, a ROM 1193, a CPU 1195, and an input/output port 1197, which are connected to each other by a data bus 1199.

As shown in FIG. 19, a start switch 1201 for starting the image transfer device 1010 is connected to the input side of the input/output port 1197. Also, on the output side, motor 1054.1092.1116.1162.117
8.1246 is connected, and further solenoid valve 1187
via air cylinder 1104.1148.1156
is connected.

Next, the operation of this embodiment will be explained according to the flowchart shown in FIG. 20.

When the image transfer device 1010 is powered on by the startup switch 1201, initialization of the image transfer device 1010 is executed in step 1300.

By this execution, the guide plate 1030 moves to the normal position of the working part 1018, and the positioning pin 1040 also moves downward to the normal position. The brush 1060 is located on the insertion side of the conveyed sheet 1034. The temporary fixing roller 1102 is moved upward by the air cylinder 1104 and comes into pressure contact with the heat roller 1110. The heated transfer rollers 1136 and 1138 are each moved away from each other by air cylinders 1148 and 1156. That is, the conveyed sheet 1034
The transport path is in an open state.

In this state, the motors 1162 and 1178 are started, and the heated transfer rollers 1136 and 1138 are rotated.

Furthermore, the fan 1200 starts operating and the receiving part 1024
Blow air inward.

Further, each heater has started heating the heat roller 1110 and heating transfer rollers 1136 and 1138.

When the temperature of the heated transfer roller rises, the temperature is adjusted, and transfer becomes possible, a start switch is turned on to raise the positioning pin 1040 (step 1301).

From this state, in step 1302, the motor 1054 is activated to raise the positioning pin 1040 together with the flat bar 1042. This causes the flat bar 1042 to move to the operating base 102.
9 into the opening 1036 of the locating pin 104.
0 passes through the through hole 1030A of the guide plate 1030 and projects above the guide plate 1030. cover sea) 1100
has been peeled off by a peeling mechanism 1019 in advance. A positioning hole 1028A of an image receiving sheet 1028 is set on this guide plate 1030 by inserting it into a positioning pin 1040. Next, an image sheet (1026) is placed on the image receiving sheet 1028.
Insert and set the positioning hole 1026A into the positioning pin 1040. In this case, the image sheet 1026 and the image receiving sheet 102g can be easily aligned using the positioning pin 1040.

In step 1304, the conveyed sheet 1034 is transferred to the workbench 0.
29, the operator turns on a start switch (not shown) in step 1305.

In step 1306, the motor 1092 is activated, and the brush 1060 starts moving toward the back from the insertion side of the conveyed sheet 1034. As a result, air remaining between the image sheet 1026 and the image receiving sheet 1028 is removed and flattened.

When the brush 1060 moves to the front of the temporary fixing part 1020, the operation of the motor 1092 is stopped in step 1308, and the movement of the brush 1060 is stopped.

Next, in step 1310, motor 1054 is activated and positioning pin 1040 is lowered. As a result, the positioning pin 1040 is removed from the guide plate 1030. Step 1
At 312, the motor 1246 is activated and the guide plate 1030 moves on the workbench 1029 toward the temporary fixing part 1020.

In this case, when the conveyed sheet 1034 is being conveyed in step 1313, the cover 1100 is still being peeled off by the peeling mechanism 1019. At the same time, the air cylinder 1104 is operated in step 1314, and the temporary fixing roller 11
02 descends. The sheet to be conveyed 1034 is pressed and heated from the leading end by the temporary fixing roller 1102 through the cover 1100, and is temporarily fixed. When the leading end of the conveyed sheet 1034 is conveyed while being suppressed and heated, the cover sheet 1100 is separated from the peeling mechanism 1019 and begins to cover the conveyed sheet 1034, becoming a conveyed sheet body 1035 as it is conveyed. Note that this temporary fixing roller 1102
When positioned upward by the air cylinder 1104, it is in close contact with the heat roller 1110 and is heated.

Further, since the temporary fixing roller 1102 is formed as a skewer-shaped roller, a plurality of temporary fixing positions are provided along the conveyance direction of the conveyed sheet body 1035. For this reason, the air between the temporary fixing positions easily escapes to the rear in the conveying direction.
In the next step 1316, the heated transfer roller 1136.11
The image sheet is pushed out when the image sheet is held and conveyed by the image receiving sheet 38, and no air bubbles are generated between the image sheet and the image receiving sheet during transfer.

Air cylinder 1148.1156 in step 1316
is activated, the heated transfer roller 1136 is lowered, and the heated transfer roller 1138 is raised. As a result, the conveyance path of the conveyed sheet body 1035 is closed, and the sprocket 115
A one-way clutch 1143 in the roller 8 operates to synchronize the circumferential speed of the heated transfer roller 1138 and the circumferential speed of the heated transfer roller 1136. Actually, the circumferential speed of the heated transfer roller 1136 is set to be slower than that of the heated transfer roller 1138.

The conveyed sheet 1035 is inserted between the heated transfer rollers 1136 and 1138. In this way, the sheet to be conveyed 1035 is pressed and held by the heated transfer rollers 1136 and 1138, and is transferred while being conveyed and heated.

In step 1320, after the conveyed sheet body 1035 passes through the temporary fixing section 1020, the temporary fixing roller 1102 is raised. In step 1322 the heated transfer roller 1136.113
8 moves to open the conveyance path for the conveyed sheet body 1035.

In this case, the conveyed sheet body 1035 is conveyed to the transfer unit 1022 by the motor 1246 and then conveyed by the motor 1178. That is, the speed at which the motor 1178 is transported is set faster than the speed at which the motor 1178 is transported by the driving force of the motor 1246, and is connected via the one-way clutch 1254, so the heating transfer rollers 1136 and 1138 are Drive motor 1
178.

In step 1326, the conveyed sheet body 1035 is transferred to the transfer unit 1.
022, the operation of the motor 1246 is stopped and the movement of the guide plate 1030 is stopped. At this time, the conveyed sheet body 1035 has moved to the receiving section 1024, and the conveyed sheet body 1035, which has been heated to a high temperature by the transfer section 1022, is cooled at the receiving section 1024.

At step 1328, motor 1092 is activated and brush 1
060 starts moving in the direction of the original position.

In step 1330, the motor 1092 is driven in reverse, and the brush 1060 moves toward the positioning mechanism 1038 and stops.

Next, in step 1332, the motor 1246 is driven in reverse to move the guide plate 1030 to the working section 1018 at high speed. The guide plate 1030 that has moved at high speed to the end of the working section 1018 moves at low speed in step 1334 and stops in step 1336.

This completes the transfer, and the operator moves to the peeling mechanism 1019.
Hold the swinging part 1507 with your hand and swing it, and at the same time extend the arm 1500 to cover the adhesive roller 504) 1
The swinging portion 150 is brought into contact with the vicinity of the end on the sending side of the
Release 7. Then, the arm 1500 of the swinging part 1507 is swung to the upright position by the weight 506 and contracted, and the cover sheet 1100 is peeled off to the vicinity of the end on the temporary fixing part 1020 side. After the base layer of the image sheet 1026 is peeled off from the image receiving sheet 1028 in this peeled state, the image receiving sheet 1028 is removed from the guide 1030.

Next, in step 1338, the operator determines whether to return to before step 1300 or to end. Step 1300
When returning to the previous step, the following steps are executed.

In this way, in this embodiment as well, the cover sheet 1100 is easily peeled off by the peeling mechanism 1019, and
The cover sheet 1100 automatically transfers the conveyed sheet 1034.
It is designed to cover.

In addition, in this embodiment, since the separation position of the cover sea) 1100 is lower than that of the first embodiment, the cover sea) 110
0 falls smoothly.

In this embodiment, the return of the brush 1060 to the initial position occurs while the conveyed sheet body 1035 is being cooled, but after the conveyed sheet body 1035 passes through the temporary fixing section 1020, that is, after step 1314, the brush 1060 returns to its initial position. It's fine at the moment.

In addition, in this embodiment, the image sheet) 1026 is used as the image receiving sheet).
1028, the apparatus of the present invention is also used in cases where the transferred image receiving sheet 1028 is superimposed on a transfer sheet such as paper and paper transfer is performed. In this case, it is also possible to perform the transfer operation without using the positioning pin 1040 of the positioning mechanism 1038 and the temporary fixing roller 1102 of the temporary fixing section 1020.
