Description

Detailed Description of the Invention [Industrial Application Field] The present invention relates to an image recording device, and particularly to an image recording device that performs image recording processing while conveying a photosensitive material and an image-receiving material, thereby obtaining an image on the image-receiving material. Regarding.

[Prior Art] An image recording device that exposes an image on a manuscript or the like onto a photosensitive material, heats and develops the photosensitive material, and then overlaps it with an image-receiving material and pressurizes it, thereby transferring the image to the image-receiving material to obtain an image. Are known. The photosensitive material used in this type of image recording apparatus is wound into a roll and stored in a magazine, and is sequentially pulled out from the outer periphery and cut into predetermined lengths. The photosensitive material after cutting is transported to an exposure section, where the image on the original film is exposed.

After exposure, the photosensitive material is sent to a heat development section where it is heated to about 80°C~
The material is conveyed and held between a heating drum heated to 200'C and an endless pressure belt, and is thermally developed.

The photosensitive material thermally developed by the heat developing section is conveyed to the overlapping section, where it is overlapped with an image receiving material supplied from a manual feed section or an n-type sheet cassette, and then conveyed to the pressure transfer section. In this pressure transfer section, each material is pressed while being overlapped, so that the image recorded on the photosensitive material is transferred to the image-receiving material.

The image-receiving material and the photosensitive material on which the image has been transferred are sent to a peeling section and peeled off, and only the photosensitive material is transported to a waste tray and discarded. On the other hand, after the image-receiving material is separated from the photosensitive material, it is conveyed to a fixing section, and after the image is fixed by being irradiated with ultraviolet light by an ultraviolet lamp, the image-receiving material is taken out of the case.

As described above, since the image recording process for obtaining the image of the original film on the image-receiving material requires a plurality of steps, the conveyance path of each material, especially the photosensitive material, in the five-image recording apparatus is inevitably long. Therefore, conventionally, in order to make a single image recording apparatus compact, each processing section is arranged close to each other, and the conveyance path of each material is bent.

[Problem to be solved by the invention] By the way, when a photosensitive material or image-receiving material becomes jammed (so-called jam) during transportation, it is necessary to manually operate a jam removal knob that is linked to a transportation means such as a transportation roller. It was necessary to move the clogged material or the material located on the conveyance path to the outlet and remove it. In this case, i
As mentioned above, in conventional image recording apparatuses, there is a problem that this process is time consuming and complicated because the conveyance path is long.

In particular, in the pressure transfer section, were the materials pressed together in an overlapping state? & (i.e., near the peel # area), there is a strong tendency for this jam to occur, and in this case, the photosensitive material that has been pulled out of the magazine and remains unprocessed on the conveyance path - A is disposed of as the jam is processed. However, there was also a problem in terms of energy saving.

On the other hand, some types of image recording apparatuses have a main body or a structure that is divided into upper and lower parts. In this type of image recording device,
Since the inside of the device can be opened by moving the upper part of the device, if a jam occurs, the inside can be opened and the jammed material can be directly taken out and disposed of easily, which appears to be an excellent feature at first glance.

However, if you open the inside and take it out directly, 1
There were disadvantages such as the image receiving material not being completely fixed could get dirty by touching it with one's hands. In addition, there are 100
It was also dangerous because there were heating drums and other equipment that were heated to around 30°F.

A branch means communicating with the outside of the machine is provided in the middle of the conveyance path of the photosensitive material or the image receiving material.

[Operation] In the image recording apparatus having the above configuration, the conveyance path communicates with the outside of the machine by the branching means. Therefore, when taking out materials located on the transport route, they can be taken out of the machine via the branching means without having to pass through the normal transport route, making it quick and easy even if the transport route is long. can be taken out.

, a heat developing section 26, a lower reversing section 70, and a lower reversing section 82.

Next, the operation of this embodiment will be explained.

The photosensitive material 18 which has been pulled out from the magazine 16 by the conveyance roller 19 and cut into a predetermined length by the cutter 20 is conveyed by the conveyance roller 21 to the exposure section 22, and is exposed as an image by the exposure section 2t24. The exposed photosensitive material 18 is conveyed to the heat developing section 26 while being held between a nipping and reversing roller 72 and a nipping and reversing roller 74 of the lower reversing section 70 . In this case, the first branch pawl 78 is inoperative and the branch path 76
is in a closed state, the photosensitive material 18 conveyed from the exposure section 22 is sent to the lower reversing section 70 without entering the branch path 76. Further, the light shielding plate 77 of the branch path 76 is in a closed state, so that light does not enter into the photosensitive material 14 through the branch path 76 and inadvertently expose the photosensitive material 18.

The photosensitive material 18 sent to the L reversing section 70 changes its conveying direction by approximately 180 degrees by the nipping and reversing rollers 72, and is conveyed to the heat developing section 26, where it is carried inside from the left side in FIG. The photosensitive material 18 is conveyed and held between a heating drum 28 heated to 80 DEG C. to 200 DEG C. by a halogen lamp 32 and an endless pressure belt 30, and then thermally developed.

The photosensitive material 18 that has been roughly thermally developed is wound around the reversing roller 84 of the lower reversing section 82 and is reversed until it reaches the overlapping section 34.
sent to. In this case, since the branch guide 90 is inoperative and the branch path 88 is in a closed state, the thermally developed photosensitive material 18 sent out from the heat developing section 26 is transferred to the branch path 88.
It is sent to the lower reversing section 82 without entering. Further, the light shielding plate 89 of the branch path 88 is in a closed state, so that no light enters into the interior of the light source 14 through the branch path 88.

The thermally developed photosensitive material 18 sent from the heat developing section 26 to the lower reversing section 82 changes its transport direction by approximately 180 degrees again by the reversing roller 84, and is supplied to the overlapping section 34 from the left side in FIG. be done.

The photosensitive material 18 conveyed to the overlapping section 34 is overlaid on the image receiving paper 42 supplied from the manual feed section 40 or the detachable sheet cassette 36.

The photosensitive material 18 and the image-receiving paper 42 which have been superimposed in the alignment section 34 are both sent to the pressure transfer section 44, where they are sandwiched and pressure-bonded to the pressure roller 46 in the aligned state. Here, the color developer applied to the image-forming surface of the image-receiving paper 42 reacts with the color image-forming substance transferred from the photosensitive material 18, and the image recorded on the photosensitive material 18 is transferred to the image-receiving paper 42.

The image receiving paper 42 on which the image has been transferred and the photosensitive material 18 are sent to a peeling section 50 and peeled off from each other, and only the photosensitive material 18 is transported to a waste tray 52 and discarded.

On the other hand, after being separated from the photosensitive material 18, the image receiving paper 42 is conveyed to a fixing device 54, and after being irradiated with ultraviolet light by an ultraviolet lamp 56 to fix the image, it is taken out of the machine 14.

If the photosensitive material 18 or the image-receiving paper 42 becomes jammed (so-called jam) during transportation during such image recording processing, manually operate the jam removal knob 94 that is linked to each transportation roller and the nipping and reversing roller. It is possible to remove the jammed material or the material located on the conveyance path to the outside of the machine base 14.

That is, the first unit 14A of the machine base 14 is moved to open the inside. At this time, if the material sensor 80 or the material sensor 92 does not detect the presence of the photosensitive material 18 (therefore, if the photosensitive material 18 is not present between the cutter 20 and the reversing section 70 or within the heat developing section 26), ) Branch claw 78
Alternatively, an activation signal of the branch guide 90 is outputted and activated, and the branch path 76 or the branch path 88 is opened. Furthermore, at the same time, the light shielding plate 77 and the light shielding plate 89 are brought into an open state, thereby opening the outlet of each branch path.

When the jam removal knob 94 is operated after the branch path 76 or the branch path 88 is opened, each of the conveying rollers and the nipping and reversing rollers are rotated in conjunction with each other to move the photosensitive material 18. In this case, the photosensitive material 18 remaining between the cutter 20 and the upper reversing section 70 is discharged from the branching path 76 to the outside of the machine 14 without being supplied to the nipping reversing roller 72 by the branching claw 78; The photosensitive material 18 in the heating and developing section 26 is discharged from the machine stand 14 through a branching path 88 without being supplied to the reversing roller 84 by the branching guide 90 .

In this way, even if a jam occurs along the long conveyance path for each material, the jammed material or the material located on the conveyance path can be quickly taken out via the branch path.

Note that the branching guide 90 provided on the lower reversing section 82 may be a branching claw like the branching claw 78 provided on the upper reversing section 70 .

[Effects of the Invention] As described in Section 1 below, the image recording apparatus according to the present invention is an image recording apparatus that performs image recording processing while conveying a photosensitive material and an image-receiving material within a machine body to obtain an image on the image-receiving material. Since a branching means communicating with the outside of the machine is provided in the middle of the conveyance path of the photosensitive material or image-receiving material, if a jam occurs on the conveyance path of the SA optical material or image-receiving material, it can be removed. This has the effect of making things easier to do.
