Abstract

PURPOSE:To prevent the rear end detecting marks for detecting rear ends from affecting images by using at least either of a photosensitive material or image receiving material which is previously attached with the rear end detecting marks for detecting the prescribed length from the rear end. CONSTITUTION:The roller photosensitive material 20 is housed in a 1st magazine 16 and the rolled image receiving material 22 is housed in the 2nd magazine 18. The rear end detecting marks 108, 109 for detecting the position of the prescribed length from the rear end are previously attached to the rear surface of at least either of the photosensitive material 20 and the image receiving material 22. The rear end detection processing can then be executed by detecting the rear end detecting marks 108, 109 during the image processing. The rear end detecting mark 109 is invisible from the surface of the image receiving material 22 even if the image recording processing is executed by using the material atached with the rear end detecting marks 108, 109 and, therefore, no influence is exerted to the recorded images.

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 extracts a photosensitive material from a magazine and exposes it to light, and also pulls out an image receiving material from the magazine and receives an image exposed on the photosensitive material. The present invention relates to an image recording device that transfers onto a material.

[Prior Art] An image recording apparatus is known in which a photosensitive material is drawn out from a magazine and exposed to light, an image receiving material is drawn out from the magazine, and an image exposed on the photosensitive material is transferred to the image receiving material by thermal development transfer.

In this type of image recording apparatus, the photosensitive material 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 cut photosensitive material is conveyed to an exposure section, and the image of the document is exposed. The exposed photosensitive material is coated with water in a water coating section, and then conveyed to a superposition section where it is superimposed on an image-receiving material.

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 predetermined lengths. For this reason, in the image recording apparatus, if the photosensitive material runs out while being drawn out, the image recording process is performed without being supplied with a length of photosensitive material corresponding to the document, and the image receiving material is wasted. Also, if the image-receiving material runs out while being pulled out,
Since the image recording process is performed without being supplied with an image-receiving material of a length corresponding to the original, the photosensitive material is wasted. Conventionally, in order to eliminate this waste, a hole or notch for detecting a position of a predetermined length from the rear end is drilled in advance in the photosensitive material and image receiving material, and the hole or notch is drilled in advance during the image recording process. If detected, the image recording process is continued as is, and the next photosensitive material and image receiving material are stopped from being pulled out, and furthermore, a message is displayed that the photosensitive material or image receiving material has run out.

[Problems to be Solved by the Invention] However, in the above-mentioned conventional technology, an image is exposed to a photosensitive material having holes etc., and the image is transferred to an image receiving material having holes etc. , holes, etc. affect the image.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide an image recording device in which a trailing edge detection port for detecting a trailing edge does not affect an image.

[Means for Solving the Problems] In order to achieve the above object, the present invention involves pulling out a photosensitive material from a magazine and exposing it to light, pulling out an image receiving material from the magazine, and transferring the image exposed on the photosensitive material to the image receiving material. The image recording apparatus is characterized in that at least one of a photosensitive material and an image-receiving material is used, the rear end of which is provided with a rear end detection port for detecting a position a predetermined length from the rear end.

[Operation] According to the present invention, when an image recording operation is started, the photosensitive material is pulled out from the magazine and exposed to light, and at the same time, the image-receiving material is pulled out from the magazine, and the image exposed on the photosensitive material is transferred to the image-receiving material. A rear end detection port for detecting a position a predetermined length from the rear end is provided on the back surface of at least one of the photosensitive material and the image receiving material. By detecting this trailing edge detection port during image recording processing, it is possible to perform the same trailing edge detection post-processing as in the prior art. Since the trailing edge detection port is printed on the back side of at least one of the photosensitive material and the image receiving material, an image is exposed to the photosensitive material provided with the trailing edge detection port.
Alternatively, even if an image is transferred to an image receiving material provided with a trailing edge detection port, the trailing edge detection port does not affect the image.

[Effects of the Invention] As explained above, according to the present invention, the rear end detection port for detecting a position at a predetermined length from the rear end is provided on the back surface of at least one of the photosensitive material and the image receiving material. Even if an image recording process is performed using a material provided with an edge detection port, the trailing edge detection port is not visible from the surface of the image-receiving material, and a good recorded image can be obtained, which is an excellent effect.

is transported to a standby roller 72 by transport rollers 68 and 70 that are constantly rotating. In step 400, it is determined whether or not the standby sensor 130 is turned on. If it is determined that the standby sensor 130 is turned on, in step 402, the drive of the standby roller 72 is stopped and the image receiving material 22 is stopped. In step 404, it is determined whether or not the flag T is set. If it is determined that the flag T is not set, that is, if the rear end detection port 109 of the image receiving material 22 is not detected, the step 208 in FIG. do. On the other hand, if it is determined that the flag T is set in step 404, that is, if the trailing edge detection port 109 of the image material 22 is detected, then in step 406, after the trailing edge detection mark 109 is detected, The extraction length K is calculated based on the number of clock pulses. In step 408, the pull-out length K calculated in step 406 is subtracted from the length between the rear end detection port 109 and the rear end of the image-receiving material 22 (for example, A3 lengthwise), and the remaining amount N of the image-receiving material 22 is calculated.
is calculated and jumps to step 208 in FIG.
