Abstract

PURPOSE:To prevent photosensitive material from being used wastefully and to insure the leading edge of image receiving material to be discarded against being carried to an accumulating part by pulling out only the image receiving material by a prescribed length when a magazine is set and discarding the image receiving material to a discard box after cutting. CONSTITUTION:An image exposed on the photosensitive material 20 is transferred onto the image receiving material 22 cut in a prescribed length, and both materials are separated after transfer. Only the photosensitive material 20 is discharged to the discard box 96, while the image receiving material 22 is carried to the accumulating part 10b. When a 2nd magazine 18 housing the image receiving material 22 is set, the photosensitive material 20 is not pulled out of a 1st magazine 16 so that the leading edge of the image receiving material 22 can overlap. After only the image receiving material 22 is pulled from its leading edge by a prescribed length to be cut, it is discharged to the discard box 96. As a result, the photosensitive material 20 is not used wastefully. Since the leading edge of the cut image receiving material 22 is discharged to the discard box 96, the leading edge of the image receiving material to be discarded is not carried to the accumulating part 10b.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an image recording device, and in particular, an image recording device that transfers an image exposed on a photosensitive material to an image receiving material that is pulled out from a magazine and cut into a predetermined length; The present invention relates to an image recording apparatus that peels off both materials after transfer, discharges the photosensitive material to a disposal box, and conveys the image-receiving material to a collecting section.

[Prior art] An unexposed photosensitive material is pulled out and cut to a length corresponding to a specified size, and then exposed. At the same time, an unused image-receiving material is pulled out and cut to a length corresponding to a specified size, and the photosensitive material is exposed. 2. Description of the Related Art An image recording apparatus is known that transfers an image onto an image receiving material.

In this type of image recording device, unexposed photosensitive material is wound up into a roll and stored in a magazine.
By specifying the image recording size, the images are sequentially pulled out from the outer periphery and cut into lengths corresponding to the specified size. The cut photosensitive material is conveyed to an exposure section, and the image of the document is exposed. The exposed photosensitive material is conveyed to the overlapping section, where it is overlaid on the image-receiving material and transferred. This image-receiving material is also wound up into a roll and stored in a magazine, and is sequentially pulled out from the outer periphery and cut into lengths corresponding to a designated size. After transfer, the photosensitive material is discharged into a disposal box, and the image-receiving material is transported to a collection tray. If the remaining image-receiving material becomes less than the length corresponding to the specified size, remove the image-receiving material magazine, set a new magazine, and remove the specified length from the leading edge of the image-receiving material from the magazine by hand. It is pulled out and held between conveyance rollers provided in the image recording device.

[Problems to be Solved by the Invention] However, in the above-mentioned conventional technology, when the image-receiving material is pulled out by hand for a predetermined length from the magazine, the tip of the image-receiving material is touched, so fingerprints or the like may be left on the emulsion surface of the tip. The tip may get stuck or the tip may break. If image recording is performed in this case, the image exposed on the photosensitive material will be recorded on the image-receiving material that has fingerprints, etc. or is bent, which will impair the quality of the image obtained on the image-receiving material and cause the photosensitive material to deteriorate. The problem is that it's wasted. Moreover, since the image-receiving material whose image quality has been deteriorated is conveyed to the accumulation section, there is a problem in that the image-receiving material conveyed to the accumulation section must be discarded.

The present invention has been made to solve the above-mentioned problems, and prevents the photosensitive material from being wasted due to the quality of the image on the image receiving material being impaired when a magazine containing image receiving material is set. It is an object of the present invention to provide an image recording device that can prevent the leading edge of image-receiving material to be discarded from being conveyed to a stacking section, and eliminates the need to discard the image-receiving material that has been conveyed to the stacking section.

[Means for Solving the Problem] In order to achieve the above object, the present invention transfers an image exposed on a photosensitive material to an image receiving material that is pulled out from a magazine and cut into a predetermined length, and uses a transfer post-poster. In an image recording device that peels off and discharges the photosensitive material to a disposal box, and conveys the image receiving material to a collection section, when the magazine is set, only the image receiving feed is pulled out to a predetermined length from the tip, cut, and then transferred to the disposal box. It is characterized by being discharged.

[Function] According to the present invention, when a magazine containing image-receiving material is set, only the image-receiving material is pulled out a predetermined length from the tip and cut without pulling out the photosensitive material 11, so that the photosensitive material is not wasted. do not become. Furthermore, since the leading end of the cut image-receiving material is discharged into a disposal box where photosensitive materials are normally discarded, the leading end of the image-receiving material to be discarded is not conveyed to the accumulation section.

[Effects of the Invention] As described above, in the present invention, when a magazine containing image-receiving material is set, the photosensitive material is not pulled out so as to be overlapped with the leading end of the image-receiving material, so that the photosensitive material is not wasted. In addition, only the image-receiving material is pulled out to a predetermined length from the tip and cut, and then the tip of the image-receiving material is discharged to the disposal box, so the tip of the image-receiving material to be discarded is not transported to the accumulation section, but is transported to the accumulation section. This has an excellent effect in that there is no need to discard the image-receiving material that has been used.
