DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus and a method for loading a sheet-like image-forming material from a package in which the sheet-like image-forming material is packaged in a packaging bag.

[0002]

2. Description of the Related Art Conventionally, in the medical field, diagnosis or the like has been performed by directly or indirectly exposing an image of a human body or the like to a sheet film to form an image. As shown in FIG. 5A, these sheet films are laminated, surrounded by a U-shaped backing paper, and further supplied in a state of being shielded from light by a light shielding bag. The reason why the sheet film is put in the light-shielding bag in this way is that the sheet film has room illumination light (usually 1000
This is because an image is formed as a latent image by being exposed to sunlight or sunlight, so that external light is not irradiated.

In order to form an image on the sheet film indirectly with a laser imager or the like or to form an image directly with an X-ray photographing apparatus (a sheet film is put into a cassette by a supplier or the like), a sheet film loading apparatus is used. Then, the sheet film taken out of the light-shielding bag is loaded, but in the conventional sheet film, the light-shielding state from the external light has to be maintained as described above.
For that purpose, various devices have been devised.

[0004] One example is to load a sheet film by loading a magazine as shown in FIG. 5 (b) into a loading device body. In this case, the upper lid of the magazine pulled out from the loading device body (not shown) is opened, and the sheet film is set in the magazine together with the light shielding bag. At this time, the light shielding bag is placed between the upper roller and the lower roller or /
And between the light shielding wall and the outside of the magazine. Thus, the inside of the magazine is maintained in a light-shielded state. Then, by opening one end of the light-shielding bag protruding outside the magazine and pulling the other end, the light-shielding bag can be pulled out, and the sheet film can be left in the magazine, and the magazine is loaded into the loading device body. Then, the sheet film is loaded.

[0005]

As described above, in the conventional sheet film, since a latent image is formed by room illumination light or sunlight, it is very difficult to handle the sheet film, especially when loading the sheet film. Complicated work was required, and the operability was poor.

However, in recent years, no image is formed by room illumination light or sunlight, and high-density energy light (for example, about 3
A sheet-like image forming material that forms a latent image with a light amount (energy) of not less than 00,000 W / cm ² has been researched and developed. For example, as described in JP-A-9-106079, this sheet-shaped image forming material is
This sheet-like image is formed by laminating a first sheet having a color material layer on a support and a second sheet having an adhesive layer on a second support with the color material layer and the adhesive layer facing each other. After irradiating the forming material with high-density energy light to melt and deform, scatter, burn or evaporate a part of the material (these are referred to as ablation), a latent image is formed.
By peeling off the sheet and the second sheet, an image (visible image) is formed on the sheet (since these are already visible images, there is no need to perform development processing in the next step).

Therefore, with the development of a new sheet-like image forming material, it becomes possible to handle the sheet image differently from a conventional sheet film in which a latent image is formed by room illumination light or sunlight. It is greatly desired. In particular, in the case of a conventional sheet film, the operation for loading the sheet film is very complicated and the operability is poor.

Accordingly, the present invention provides a method for removing a sheet-like image forming material from a package in which the sheet-like image forming material is packaged in a packaging bag and loading the same in a loading device.
It is an object to improve operability.

[0009]

The object of the present invention is to provide a sheet-like image forming material loading apparatus for taking out and loading a sheet-like image forming material from a package in which the sheet-like image forming material is packed in a packaging bag.

And a guide unit capable of guiding the upper surface of the packaging bag when the packaging bag is pulled out. In the method for loading a sheet-like image forming material to take out and load the sheet-like image forming material from the packaged body,
The package is placed on the loading table pulled out from the body of the loading device, and the end of the loaded packaging bag is opened.After the package is placed, the package is placed on the body of the loading device. A sheet for loading the sheet-shaped image forming material into the loading device, setting the loading table on the main body of the loading device while passing below the guide member, pulling out the packaging bag while the upper surface is guided by the guide member; The problem can be solved by a method for loading the image-formation material.
