Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to the recording of one image recording material and the other image recording material while the other image recording material is wound around the outer periphery of a heating drum while being bonded by a bonding roller and subjected to heat development transfer processing. The present invention relates to an image recording device that transfers an image onto a material.

[0002]

2. Description of the Related Art As an image recording material, there is known an image recording apparatus which performs an image recording process using, for example, a photosensitive material and an image receiving material.

In this type of image recording apparatus, the photosensitive material and the image receiving material are respectively wound and accommodated in roll-shaped magazines in a light-shielding magazine. Each time an image recording process is performed, a pull-out roller is used. It is sandwiched and used by sequentially pulling it out. Further, the image recording apparatus is provided with a water coating section for coating the image forming solvent on the photosensitive material, and further, from a heating drum and an endless pressure welding belt which is in pressure contact with the outer circumference of the heating drum and rotates together with the heating drum. The thermal development transfer section is arranged.

The photosensitive material, which is pulled out from the magazine by a predetermined size by a drawing roller and cut, is exposed to an image while being conveyed while being nipped and conveyed by a conveying roller, and further, water is applied as a solvent for image formation in a water application section, and then heat is applied. It is sent to the development transfer section. On the other hand, like the photosensitive material, the image receiving material is pulled out from the magazine by a predetermined size by a drawing roller and cut, and is fed to the heat development transfer section in synchronization with the photosensitive material by the conveying roller. In the heat development transfer section, the photosensitive material after water application is superposed on the image receiving material by the laminating roller, and in this state, the photosensitive material is closely wound around the outer periphery of the heating drum. Further, both materials are sandwiched and conveyed between the heating drum and the endless pressure contact belt so that the photosensitive material is thermally developed and an image is transferred to the image receiving material, and a predetermined image is formed (recorded) on the image receiving material. is there.

[0005]

By the way, in such a conventional image recording apparatus, the peripheral surface of the laminating roller and the peripheral surface of the heating drum after the front end portion of the photosensitive material has passed the squeeze roller pair of the water application portion. If the relative angle to the image receiving material is too small when it is inserted between the two materials, air is entrapped between them and both materials come into close contact with each other, resulting in a problem that an image defect occurs. On the other hand, when the relative angle between the two materials is too large in the state of being inserted between the peripheral surface of the laminating roller and the peripheral surface of the heating drum, the reaction of the leading end of the photosensitive material with the peripheral surface of the heating drum is caused. The photosensitive material may bend slightly. In this case, the bent photosensitive material partially re-contacts the peripheral surface of the lower roller of the squeeze roller pair. Therefore, the water as the image forming solvent attached to the peripheral surface of the squeeze roller pair is attached again to the photosensitive material, so that there arises a problem that the water application amount changes and an image defect occurs.

Further, when the lamination of the photosensitive material and the image receiving material progresses and the rear end portion of the photosensitive material passes through the squeeze roller pair, the tension due to bending acts on the rear end portion of the photosensitive material. A force is generated to move in the direction of elimination. Therefore, the rear end portion of the photosensitive material moves in the direction in which the rear end portion of the photosensitive material approaches the image receiving material, and the rear end portion of the photosensitive material comes into contact with the image receiving material in the state before the bonding by the bonding roller. Therefore, there is a problem that an image defect occurs.

That is, there is a problem that an image defect occurs due to the behavior of each of the front end portion and the rear end portion of the photosensitive material.

In consideration of the above facts, the present invention can prevent unnecessary behaviors at the front end portion and the rear end portion of the image recording material and can bond the image recording material with the image receiving material in a good condition. It is an object to obtain an image recording device that can prevent the occurrence.

[0009]

According to another aspect of the present invention, there is provided an image recording apparatus in which an image forming solvent is applied after image exposure and then an excess image forming solvent is squeezed out by a squeeze roller pair. The recording material and the other image recording material for image transfer are wound around the outer circumference of the heating drum while being bonded by the bonding roller, and the image is transferred to the other image recording material by performing heat development transfer processing. In the image recording device, the leading end of the one image recording material after passing through the squeeze roller pair is sent out toward a guide plate provided between the squeeze roller pair and a laminating roller, and It is characterized in that the squeeze roller pair is arranged so as to be conveyed along the guide plate until being sandwiched by the laminating roller and the heating drum.

An image recording apparatus according to a second aspect of the present invention is the image recording apparatus according to the first aspect, in which the front end portions of the two image recording materials are sandwiched by the laminating roller and the heating drum. The squeeze roller pair is arranged so that the relative angle between both image recording materials is in the range of 45 to 50 degrees, and the squeeze roller pair is engaged with the rear end portion of the one image recording material after passing through the squeeze roller pair. And a guide auxiliary roller for preventing contact with the other image recording material before the bonding by the bonding roller.

[0011]

According to the image recording apparatus of the present invention, one of the image recording material, on which the image forming solvent is applied after the image exposure and thereafter the excess image forming solvent is squeezed out by the squeeze roller pair, and the image transfer material for image transfer. The other image recording material is wound around the outer periphery of the heating drum while being bonded by the bonding roller, and the heat development transfer process is performed to record an image on the other image recording material.

Here, the leading end of one of the image recording materials after passing through the squeeze roller pair moves to the peripheral surface of the laminating roller while being guided by the guide plate, and the leading end of the one image recording material adheres to the laminating roller and the heating drum. It is conveyed along the guide plate until it is nipped by, and is securely inserted into the peripheral surface of the laminating roller.

Therefore, the image recording material on one side and the image recording material on the other side are surely stuck together, and as a result, it is possible to prevent the occurrence of image defects.

According to another aspect of the image recording apparatus of the present invention, the front end portion of one image recording material after passing through the squeeze roller pair is inserted into the peripheral surface of the laminating roller and sandwiched between the heating drum. In (1), the relative angle between one image recording material and the other image recording material is regulated by the squeeze roller pair in the range of 45 to 50 degrees, and the two materials are bonded together.

Therefore, it is possible to prevent the entrapment of air due to the relative angle between the two materials being too small, and to prevent the two materials from adhering to each other and adhering well, resulting in an image defect. Further, when the front end of one of the image recording materials after passing through the squeeze roller pair is inserted into the peripheral surface of the laminating roller, even if one of the image recording materials tries to bend due to the reaction, Since the relative angle of is regulated to the predetermined angle by the squeeze roller pair, the rigidity of one image recording material is secured, and the bending of one image recording material due to the relative angle of both materials being too large is prevented, Re-contact with the peripheral surface of the squeeze roller pair is prevented. As a result, it is possible to prevent image defects from occurring.

Here, when one image recording material and the other image recording material are bonded together by the bonding roller, the trailing end of the one image recording material comes off the squeeze roller pair. For this reason, since tension is applied to the rear end of one of the image recording materials due to being bent by bonding, the one image recording material tends to move in the direction in which the tension is released. That is, the rear end portion of one image recording material tries to contact the other image recording material before the bonding by the bonding roller. However, according to the present invention, the guide auxiliary roller engages with the rear end portion of one image recording material, and the contact with the other image recording material before the bonding by the bonding roller is prevented. As a result, it is possible to prevent image defects from occurring.

Side). Therefore, even when the photosensitive material 22 or the image receiving material 94 is jammed during transport (so-called jam), the heat development transfer section 90 or the first peeling transport section is opened after the side door 15 of the machine base 12 is opened. This can be easily eliminated by moving the 130 and the second peeling / conveying unit 150 and the like open.

Next, the operation of this embodiment will be described. In the image recording apparatus 10 having the above-described configuration, in a normal image recording process using the photosensitive material 22 stored in the photosensitive material magazine 20, the document G is placed on the mounting table 14 (transparent glass plate 16) and the pressing cover 18 is provided. After closing, the magnification of the image to be recorded, the number of processed images, etc. are designated, and when a start instruction is given, image processing is started.

That is, with the photosensitive material magazine 20 set, the nip roller 24 is actuated to move the photosensitive material 22.
Are drawn out by the nip roller 24 at a speed of, for example, 50 mm / sec. When the photosensitive material 22 is pulled out by a predetermined length, the cutter 26 is actuated to cut the photosensitive material 22 into a predetermined length, and is further conveyed by the conveying roller 28 and the conveying roller 30 at a speed of 50 mm / sec, for example. After that, the photosensitive material 22 transported by the transport rollers 28 and 30
Further passes through the exposure section 34 at a predetermined speed (for example, 50 mm / sec) by the transport rollers 36 and 38. At the same time when the photosensitive material 22 is conveyed (passes through the exposure unit 34), the exposure device 40 operates.

In the exposure device 40, during normal (actual magnification) exposure, the lamp unit 42 and the mirror are illuminated while the light from the halogen lamp 52 is applied to the document G placed on the mounting table 14 in a slit shape. The unit 44 is moved along the document G (mounting table 14). As a result, the reflected light from the document G reaches the filter unit 46 via the first mirror 54 of the lamp unit 42, the second mirror 56 and the third mirror 58 of the mirror unit 44. In the filter unit 46, image formation and density (light amount) adjustment are performed by the lens 66 and the diaphragm mechanism 68, and color correction is performed by the color adjustment filter 64. The light passing through the filter unit 46 passes through the fourth mirror 60 and the fifth mirror 62 of the mirror unit 48, and then the sixth reflecting mirror 5
It is reflected by 0 and is scanned and exposed to the photosensitive material 22 located in the exposure section 34.

On the other hand, when the exposure is performed with the magnification changed, the filter unit 46 and the mirror unit 48 are moved to the predetermined positions on the optical path according to the designated magnification, and the lamp unit 42 is also used as described above. Also, the mirror unit 44 moves along the document G to scan and expose the photosensitive material 22 located in the exposure section 34.

The photosensitive material 22 that has been exposed by the exposure device 40 is once fed to the switchback unit 70, and then again passes through the exposure unit 34 by the reverse rotation of the conveying rollers 36, 38, 30 and the branching unit 74. After passing through, it is sent to the water application section 72.

In the water application section 72, the conveyed photosensitive material 2
2 is sent between the guide plate 82 and the coating tank 76 by the drive of the supply roller 78, and is nipped and conveyed by the squeeze roller 80. Here, the photosensitive material 22
Water is applied to the squeeze roller 80, and the squeeze roller 80 removes excess water to pass through the water application section 72. The photosensitive material 22 coated with water as the image forming solvent in the water coating section 72 is sent to the thermal development transfer section 90 by the squeeze roller 80.

On the other hand, as the scanning exposure of the photosensitive material 22 is started, the image receiving material 94 is also pulled out from the receiving material magazine 92 by the nip roller 96 and conveyed. When the image receiving material 94 is pulled out by a predetermined length, the cutter 98 operates and the image receiving material 94 is cut into a predetermined length. Cutter 98
After the operation of, the image receiving material 94 after cutting is guided by the guide plate 104.

0, it is conveyed by the conveyance roller 102, and is in a standby state immediately before the thermal development transfer section 90.

In the heat development transfer section 90, when it is detected that the photosensitive material 22 has been fed between the outer periphery of the heating drum 110 and the laminating roller 114 by the squeeze roller 80, the conveyance of the image receiving material 94 is restarted. Laminating roller 11
4 and the heating drum 110 is operated.

Here, the photosensitive material 22 is transferred to the heat development transfer section 90.
When it is fed to the squeeze roller 80, the front end portion of the photosensitive material 22 after passing through the squeeze roller 80 is guided by the guide plate 113 and inserted into the peripheral surface of the laminating roller 114. Further, in this state, the relative angle between the photosensitive material 22 and the image receiving material 94 is regulated by the squeeze roller 80 to a predetermined angle (range of 45 degrees to 50 degrees), and the photosensitive material 2
2 and the image receiving material 94 are attached to each other.

Therefore, the photosensitive material 22 and the image receiving material 94
It is possible to prevent air entrapment due to an excessively small relative angle, and prevent the photosensitive material 22 and the image receiving material 94 from sticking to each other and adhering well, thereby causing an image defect. Further, when the front end portion of the photosensitive material 22 that has passed through the squeeze roller 80 is inserted into the peripheral surface of the laminating roller 114, even if the photosensitive material 22 tries to bend due to the reaction at that time, the image is received with the photosensitive material 22. Since the relative angle of the material 94 is regulated to a predetermined angle by the squeeze roller 80, the rigidity of the photosensitive material 22 is secured, and the photosensitive material 22 due to the relative angle between the photosensitive material 22 and the image receiving material 94 being too large.

The photosensitive material 22 tries to move in the direction in which the tension is released. That is, the rear end portion of the photosensitive material 22 tries to contact the image receiving material 94 before the bonding by the bonding roller 114. However, in this case, the guide auxiliary roller 115 engages with the rear end portion of the photosensitive material 22, and the contact between the image-receiving material 94 before the bonding by the bonding roller 114 is blocked. As a result, defective images are prevented from occurring.

As described above, the photosensitive material 22 and the image receiving material 94 laminated by the laminating roller 114 are sandwiched between the heating drum 110 and the endless pressure contact belt 112 in the superposed state, and the Almost 1 /
2 laps (between winding roller 120 and winding roller 126)
Be transported to. Further, the light-sensitive material 22 and the image-receiving material 94 which are superposed are heated by the heating drum 110. When the photosensitive material 22 is heated during the nip and conveyance and when stopped, it releases a movable dye, and at the same time, the dye is transferred to the dye fixing layer of the image receiving material 94 to obtain an image. After that, the photosensitive material 22 and the image receiving material 94 are nipped and conveyed, and the bending guide roller 13 on the side of the heating drum 110.
When it reaches 2, the peeling claw 134 is moved by the cam 116, and the peeling claw 134 engages with the leading end of the photosensitive material 22 which is conveyed by a predetermined length ahead of the image receiving material 94, and the leading end of the photosensitive material 22. Is peeled from the outer periphery of the heating drum 110. Further, the pinch roller 136 presses the photosensitive material 22 by the returning movement of the peeling claw 134, whereby the photosensitive material 22 is wound around the bending guide roller 132 while being pressed by the pinch roller 136 and is moved laterally. Photosensitive material 2 wound around bending guide roller 132
2 is further conveyed by the sensitive material discharge roller 140 while being guided by the guide plate 138 and the guide roller 144,
It is accumulated in the waste photosensitive material storage box 146.

Meanwhile, the heating drum 1 is separated from the photosensitive material 22.
