Abstract

PURPOSE:To obtain a method and a device for recording an image by which the leading edges of a photosensitive material and an image receiving material can be uniformly stuck without being peeled in the case of sticking both materials and in which the uneven image is not caused. CONSTITUTION:The photosensitive material 16 is superposed on the image receiving material 108 by a heating drum 116 and a sticking roller 120 in a state where the leading edge is projected by specified length l. A distance l1 between the press-contact position of the roller 120 and the press-contact position of an endless press-contact belt 118 is set to be shorter than the projecting length l of the leading edge of the material 16. Therefore, the image receiving material 108 is not fed to the roller 120 and not superposed on the material 16 until the leading edge of the material 16 is inserted and held by the belt 118. While both materials 16 and 108 reach the belt 118 from the roller 120 in a state where the material 16 holds to envelope the material 108, both materials are not peeled and closely contact to be stuck by keeping a uniform state. Then, the uneven image is not caused, and the excellent image is obtained.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image recording method and apparatus for performing image recording processing by winding two different image recording materials around the outer periphery of a rotating drum as the drum rotates.

0002

2. Description of the Related Art Image recording apparatuses are known in which an image recording process is performed by tightly wrapping an image recording material around the outer periphery of a rotating drum.

In this type of image recording apparatus, for example, a photosensitive material and an image receiving material are used as image recording materials, and
The rotating drum is considered to be a heating drum. Part of the outer periphery of the laminating roller and the endless pressure belt is pressed onto the outer periphery of this heating drum. After the image has been exposed, the photosensitive material is coated with an image forming solvent such as water, and is further conveyed by nipping conveyance rollers and sent between a heating drum and a bonding roller. Here, the photosensitive material is successively sandwiched between a heating drum and a laminating roller, overlapped with an image-receiving material similarly sent in by a conveyance roller, and further held between the heating drum and an endless pressure belt in this state to be heated. It is tightly wrapped around the outer circumference of the drum. Here, both materials are sandwiched and conveyed between a heating drum and an endless pressure belt, while the photosensitive material is thermally developed and an image is transferred to the image-receiving material.

0004

[Problems to be Solved by the Invention] By the way, after the photosensitive material and the image-receiving material are once pasted together by a heating drum and a pasting roller, there is a problem in that between the time when they are sandwiched between the heating drum and an endless pressure belt, there is The material is left free and transferred. For this reason, a photosensitive material such as a film, which has relatively high rigidity, tends to advance in the tangential direction of the heating drum, while an image-receiving material, which has relatively low rigidity, tends to advance along the heating drum. therefore,
During this time, a force acts on both materials in a direction that causes them to separate from each other, and as a result, the leading ends of both materials sometimes separate.

When the photosensitive material and image receiving material that have been bonded together in this way are separated, they are then sandwiched between a heating drum and an endless pressure belt and bonded together again for development and transfer processing. Image irregularities such as unevenness occur.

The present invention takes the above-mentioned facts into consideration, and provides an image recording method and an image recording method in which a photosensitive material and an image-receiving material can be bonded uniformly without peeling of the leading edge when bonding, and image unevenness does not occur. The purpose is to obtain equipment.

[0007]

[Means for Solving the Problems] The image recording method of the invention according to claim 1 comprises: a rotating drum; a laminating roller that presses against the outer periphery of the rotating drum; Using an endless pressure belt that presses the outer periphery, two different image recording materials are successively sandwiched and bonded between the rotating drum and the bonding roller, and then the bonded state is transferred to the rotating drum and the endless belt. In an image recording method in which image recording processing is performed by sandwiching and conveying the material between a pressure belt and tightly wrapping it around the outer periphery of the rotating drum, the image that is located on the outer side with respect to the rotating drum among the two image recording materials; The recording material is conveyed in advance of the image recording material located on the inside and sent to the sandwiching and laminating position between the rotating drum and the laminating roller, and the leading end in the conveying direction of the image recording material positioned on the outside is rotated. After reaching the nipping position between the drum and the endless pressure belt, the image recording material located on the inside is sent to the nipping and bonding position between the rotating drum and the laminating roller, and the image recording material located on the outside is conveyed in the conveying direction. The image recording material is bonded together with the leading end protruding a predetermined length from the leading end in the conveyance direction of the image recording material located inside.

The image recording apparatus according to the second aspect of the present invention includes a rotating drum, a bonding roller that presses against the outer periphery of the rotating drum, and an endless pressure bonding roller that presses against the outer periphery of the rotating drum downstream of the bonding roller. a belt, and after sequentially sandwiching and bonding two different image recording materials between the rotating drum and the bonding roller, the bonded state is transferred between the rotating drum and the endless pressure belt. In an image recording apparatus that performs image recording processing by being pinched and conveyed and tightly wrapped around the outer periphery of the rotating drum, the leading edge in the conveying direction of the image recording material located on the outside with respect to the rotating drum among the two image recording materials. a predetermined length protruding from the leading end of the image recording material located on the inner side, and a position where the two image recording materials are sandwiched and bonded between the rotating drum and the bonding roller, and the rotating drum and the bonding roller. The present invention is characterized in that the distance between the endless press-contact belt and the nip conveyance start position of the two image recording materials is set to be shorter than the predetermined length.

[0009]

[Operation] In the image recording method according to claim 1, after the leading edge of one of the image recording materials located on the outside and being conveyed in advance passes through the laminating roller and is held between the rotating drum and the endless pressure belt. For the first time, the other image recording material located on the inside reaches the nipping and bonding position between the rotating drum and the bonding roller.

[0010] Therefore, at this point, already
Since the leading edge of one of the image recording materials located on the outside is held between the rotating drum and the endless pressure belt, the leading edge of the other image recording material located on the inside is held by the one of the image recording materials located on the outside. In the coated state, both materials are bonded together in close contact with each other, and the leading ends of both materials do not peel off even during the journey from the bonding roller to the endless pressure belt, and are bonded uniformly. therefore,
A high-quality image can be obtained without image unevenness.

[0011] In the image recording apparatus according to the second aspect, the leading end of one of the image recording materials located on the outside of the bonded image recording material with the leading end protruding by a predetermined length is held between the rotating drum and the endless pressure belt. , the other image recording material located on the inside reaches a sandwiching and pasting position between the rotating drum and the pasting roller, and is pasted with one of the image recording materials located on the outside.

[0012] Therefore, in this case as well, the leading ends of both materials do not peel off during the journey from the laminating roller to the endless pressure belt, and are adhered uniformly and in close contact with each other. Therefore, image unevenness does not occur and a high quality image can be obtained.

They are collected on tray 184.

Next, the operation of this embodiment will be explained.

The photosensitive material 16 drawn out from the photosensitive material magazine 14 by the nip roller 18 is cut into a predetermined length by the cutter 20. The cut photosensitive material 16 is conveyed by conveyance rollers 24 and 26, passes through the exposure section 22, and reaches the flapper 36. Here, the flapper 36 connects the photosensitive material 16 branched into two.
The photosensitive material 16 is guided to the conveyance path of the flapper 36 located on the upper side of the apparatus by entering the conveyance path located on the lower side of the apparatus and blocking it. Further, the guided photosensitive material 16 is reversed at the reversing section 34 so that its photosensitive (exposure) surface faces upward, and then conveyed from the flapper 36 to the exposure section 22 again.

In the exposure section 22 , light is irradiated onto the original 54 placed on the original placing plate 50 , and the reflected image light (image light) passes through a plurality of fixed mirrors 44 to the exposure section 22 . The material 16 is scanned and exposed.

In this case, a guide plate 70 is provided between the laminating roller 120 and the squeeze roller 68 of the water application section 62.
are arranged so that the photosensitive material 16 sent from the squeeze roller 68 is reliably guided to the bonding roller 120.

On the other hand, the image receiving material 108 is also stored in the receiving material magazine 10.
The photosensitive material 16 is pulled out from the photosensitive material 16 by a nip roller 110, further cut into a length shorter than the photosensitive material 16 by a cutter 112, and then transported to a thermal development transfer section 104 by a transport roller 114. In this case, the image-receiving material 108 is conveyed in synchronization with the conveyance of the photosensitive material 16, and is placed between the laminating roller 120 and the heating drum 116 with the photosensitive material 16 leading by a predetermined length (20 mm in this example). sent to.

The leading end of the image receiving material 108 guided to the pasting roller 120 is connected to the pasting roller 120 and the heating drum 11.
When the contact point with the photosensitive material 16 is reached, the photosensitive material 16 is sequentially overlapped with the photosensitive material 16.

It is tightly wrapped around the outer circumference of 6.

Furthermore, in this case, since the image-receiving material 108 is smaller in width and length than the photosensitive material 16, the peripheral portion of the photosensitive material 16 is made of image-receiving material on all four sides, as shown in FIG.

A predetermined pressure can be applied without each material shifting during the process, and a high-quality image without image unevenness can be obtained.

Thereafter, when the photosensitive material 16 and the image-receiving material 108 are sandwiched and conveyed and reach the lower part of the heating drum 116, a peeling claw 154 is attached to the tip of the photosensitive material 16, which is conveyed a predetermined length ahead of the image-receiving material 108. engages, and the photosensitive material 16
