Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roll recording material magazine and a mounting apparatus for the same, and more particularly to a roll recording material magazine and a mounting apparatus for allowing a roll recording photosensitive material to be wound inside the magazine.

[0002]

2. Description of the Related Art Heretofore, a roll recording material magazine of this type and this mounting apparatus have a structure in which the light-shielding material in the magazine is not exposed to light while the apparatus is at rest. ing.

A main apparatus using a magazine for a roll recording photosensitive material is a CTS (Computerized Typesetting System) plotter whose main purpose is to produce a block film on a newspaper. This master block film is exposed to a beam of light from an LD (laser diode) as a light-sensitive recording material of an unexposed silver salt photographic recording system, released after being fixed by suction, and then discharged. Is developed and completed. The LD beam is emitted perpendicularly to the surface of the recording photosensitive material from the center of the cylinder of the semi-cylindrical drum. For this reason, the recording photosensitive material is housed in a roll recording photosensitive material magazine in a roll shape and completely shielded from light.

A magazine for a roll recording photosensitive material is mounted by sandwiching a part of the front end of the rolled recording photosensitive material at a predetermined position of a CTS plotter, like a general camera film magazine. When the lid of the apparatus is closed and recording is started, the recording photosensitive material is automatically wound and loaded in the position of the above semi-cylindrical drum. When the roll recording photosensitive material is loosened during this winding, the recording is distorted.

A technique for preventing loosening of roll recording paper is described in, for example, Japanese Utility Model Laid-Open No. 62-89248. In this system, the winding mechanism is driven on the side where the roll recording paper is supplied and the side opposite the table, and the roll recording paper is fed to the table.
A rubber belt is stretched between a pulley that is interlocked with the holder shaft on the supply side and a fixed pulley that is fixedly arranged, and an appropriate tension is applied to the rubber belt.

In this structure, when the winding mechanism is driven to convey the roll recording paper, the pulley and the rubber belt rotate, and the rubber belt expands due to friction with the pulley. As a result, the rubber belt reversely rotates the pulley, and the wrinkles on the roll recording paper on the table are removed.

The above-mentioned conventional magazine for roll recording photosensitive material and the CTS plotter of this mounting apparatus have a closed structure for shielding the recording photosensitive material from light, and are generated in the magazine or this mounting apparatus. The slack of the roll recording photosensitive material cannot be removed.

The slack of the roll recording photosensitive material causes skewing of the roll recording photosensitive material, which not only affects recording accuracy but also causes a jam inside the magazine depending on the situation. is there. On the other hand, when removing the slack, the lid of the device or the magazine is opened for processing, and the roll recording photosensitive material becomes exposed to light so that it cannot be used. There is a problem of doing.

In addition, the technique described in the above-mentioned publication is
The roll recording paper is not a recording photosensitive material but is conveyed on a flat table, and there is no consideration of the function for light shielding, which is a problem in practical use with respect to the roll recording photosensitive material.

An object of the present invention is to provide a handle capable of rewinding the roll recording photosensitive material inside the magazine outside the magazine, and an apparatus equipped with this magazine also has a structure capable of operating the handle of this magazine from the outside of the apparatus. Thus, the roll recording material magazine in which the roll recording photosensitive material in the magazine can be rewound from the outside and the slack inside can be removed, and a mounting device for the same.
