Abstract

PURPOSE:To prevent a rolled material from loosening and to obviate the generation of flaws in the rolled material before use by joining the inner side of a winding core and a cylindrical body part by an adhesive piece and further allowing the joint to be released at the time of drawing out the rolled material. CONSTITUTION:The inner side of the winding core 3 and the cylindrical body part between the cylindrical body part and the winding core 3 are connected by the adhesive piece 6 via the side face of the rolled material 4. The adhesive piece 6 is so formed as to maintain the adhered state in the winding core 3 and the cylindrical body part via the side face of the rolled material 4 before the drawing out and use of the rolled material 4 and to easily release the joint of the winding core 3 and the cylindrical body part by the force for drawing out the rolled material 4. The generation of the loosening in the winding by the rotation of the rolled photosensitive material by the oscillation during transportation is, therefore, obviated. The rubbing flaws of the magazine and the rolled material by the loosened winding and the rubbing flaws, etc., of the rolled material against each other are prevented in this way.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a cassette or magazine (hereinafter referred to as "magazine") for holding rolled material.

(Prior Art) Conventionally, a relatively wide magazine for a roll-shaped photosensitive material used for printing, printing, copying, etc. has, for example, a rectangular cylindrical body part made by bending a body plate made of cardboard or plastic, etc. A roll-shaped photosensitive material wound around a core rotatably supported on the inner surface of the side plate is housed in a hollow interior formed by side plates that seal both ends of the body part in a light-shielded manner, and the winding is placed in a corner of one side of the body part. This is a magazine for a photosensitive material in which the photosensitive material is pulled out from a slot provided with a light shielding means extending along the axial direction of the core (see, for example, Japanese Patent Publication No. 59/36736).

The two side plates that seal both ends of the body are structurally equipped with grooves that engage with the edges of the body to keep out light, and rotation bearings for the core of the photosensitive material housed in the magazine. It has complex irregularities and is required to have the necessary rigidity and accurate dimensions, so it is usually molded from plastic.

Further, a slot extending in the entire axis direction of the body part provided at a corner of one surface of the body part is provided in a part corresponding to the upper lip, a lower lip connected to one surface of the body part, and a surface of each lip. It consists of a light shielding means such as a telescope.

The photosensitive material is initially stored with the tip of the photosensitive material pulled out from the slot of the magazine, and the tip is fixed with tape, for example, on the body of the magazine to prevent it from being rewound into the magazine. Transportation, etc. will be carried out. For example, when loading a magazine into a magazine mounting section of an image forming apparatus, the tape is removed and the leading end of the photosensitive material is gripped by, for example, a nip roller for conveyance of the image forming apparatus, thereby pulling out the photosensitive material.

(Problem to be Solved by the Invention) However, in conventional magazines for photosensitive materials, the roll of photosensitive material stored in the magazine becomes loose due to photographing during transportation, so vibrations during transportation may cause the photosensitive material to become loose. Scratches occur when the material rubs against the inner wall of the magazine, or when the photosensitive materials rub against each other.Furthermore, when the photosensitive materials are pulled out from the magazine, the tightness of the wrapping of the photosensitive materials also causes the photosensitive materials to rub against each other, resulting in damage to the resulting image quality. It was a loss.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a magazine for rolled materials that eliminates the above-mentioned problems, prevents the rolled materials from loosening, and does not cause damage to the rolled materials before use.

(Means and Effects for Solving the Problems) The above object of the present invention is to provide windings in a hollow interior consisting of a cylindrical body part and side plates sealing both ends of the body part, around a core pivotally supported on the inner surface of the side plate. In a magazine for rolled materials that stores loaded rolled materials and draws the rolled materials out of the cylindrical body from a slot extending parallel to the core axis of the body, the inside of the core and the body are separated. This has been achieved by a magazine for rolled materials, which is characterized in that the materials are connected by adhesive pieces, and when the rolled material is pulled out, the connections by the adhesive pieces are released.

(Embodiments) Hereinafter, embodiments of the present invention will be described based on the accompanying drawings.

FIG. 1 is a partial sectional view showing one embodiment of the magazine for rolled materials of the present invention.

The magazine for rolled materials consists of a body 1 made by bending a printing plate made of cardboard or the like into a rectangular cylinder shape, and side plates 2 closing both ends of the body 1. The edge of the body 1 engages with a groove provided on the outer circumference of the inner surface of the side plate 2, thereby shielding the inside of the magazine from light. Further, at the center of the inner surface of the side plate 2, a core 3 around which the photosensitive material 4 is wound is provided.
It has a holding shaft 5 for pivotally supporting the.

Between the body part and the winding core 3, there is a winding core 3 as shown in FIG.
The inside of the body and the body part pass through the side of the rolled material 4 1-
1 are connected by adhesive pieces 6, so that the rolled material will not become loose even due to vibrations during transportation of the magazine. That is, it is an adhesive piece for preventing winding loosening, which prevents rotation of the winding core 3 connected by the adhesive piece 6 during transportation. Therefore, the adhesive piece 6 has a shape and adhesive strength that will not break or peel off due to vibration during transportation. The adhesive piece also has the function of releasing the connection and allowing the winding core 3 to start rotating freely when the rolled material 4 is pulled out from the slot (drawing port) 7.

The adhesive piece 6 may be made of any material such as paper, plastic, or metal.

The adhesive piece 6 remains bonded to the winding core 3 and the body portion through the side surface of the roll material 4 until the roll material 4 is pulled out and used, and is rolled up by the force of pulling out the roll material 4. It is necessary that the connection between the core 3 and the body portion be easily released.

For this purpose, for example, there is a method of creating a difference between the adhesion strength of the adhesive piece 6 to the inside of the core 3 and the adhesive strength to the body part (using different types of adhesives, adhesives with different adhesive strengths to the core and the body part, etc.). (using an adhesive, etc.) or using an adhesive piece 6 that is cut between the core 3 and the body part, that is, near the core hole, by the force of pulling out the rolled material 4 (to make cutting easier, It is preferable to use an adhesive tape with perforated holes in the cut portion or an adhesive tape with a narrow cut portion.

Further, the means for preventing loosening of the roll by the adhesive piece 6 can achieve the purpose if applied to one side of the roll-shaped material, and may be applied to both sides.

The winding loosening prevention means of the present invention can be achieved by simply providing an adhesive piece 6 on a conventional magazine, so there is no need to change the magazine body, etc., and there is also the advantage that there is no need to create a new mold.

Rolled material f! +4: A photosensitive composition, for example, a silver rhodanide emulsion layer may be coated on one or both sides of the support. Further, the support used here may be polyethylene laminate paper, synthetic paper, or plastic film. The core for winding into a roll may be made of paper or plastic.

(Effects of the Invention) According to the present invention, the roll-shaped photosensitive material can be rotated by photographing during transportation by simply connecting the winding core 3 and the body part as described above with the adhesive piece 6 before sealing the end of the magazine. No loose winding will occur.

Therefore, it is possible to prevent scratches between the magazine and the rolled material due to loose winding, and scratches between the rolled photosensitive materials, and it is also possible to easily pull out the rolled material.
