Description

Detailed Description of the Invention (Industrial Application Field) The present invention provides a method for winding a winding core in a hollow interior consisting of a cylindrical body part and side plates sealing both ends of the body part, around a core that is pivotally supported on the inner surface of the side plate. The present invention relates to a magazine for rolled material that accommodates rolled material and draws the rolled material out of the magazine from a slot extending parallel to the core axis of a body portion.

(Prior Art) Conventionally, a relatively wide roll-shaped photosensitive material magazine used for printing, printing, copying, etc. has 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 sealing both ends of the body part in a light-shielded state, and in a corner of one side of the body part, This is a magazine for a photosensitive material that draws out the photosensitive material from a slot provided with a light shielding means extending along the axial direction of the core (see, for example, Japanese Patent Publication No. 5136736).
.

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 provided at a corner of one surface of the body portion and extending in the entire axis direction of the body portion has a portion corresponding to the upper lip;
It consists of a lower lip connected to one side of the body, and light shielding means such as a telescope provided on each lip side.

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 secured with tape, for example, to the body of the magazine to prevent it from being rewound into the magazine for storage and 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 rolled photosensitive material stored in the magazine becomes loose due to vibrations during transportation. Scratches can occur when the photosensitive materials rub against the inner walls 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 and cause scratches, which can affect the quality of the resulting image. It was a loss.

Therefore, JP-A-60-156058, JP-A-57-1
As disclosed in each publication of No. 28333, the core of the roll is fixed to the core bearing of the end cap of the magazine using a key (lock) to prevent rotation of the core before the photosensitive material starts to be used. Although several methods have been proposed, sufficient effects have not been achieved.

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 pulls the rolled materials out of the cylindrical body from a slot extending parallel to the core axis of the body part, a part of the core is attached with an adhesive. This is achieved by a magazine for rolled material, which is fixed to the side plate by the above-described method, and the fixation is released by a predetermined force acting on the rolled material.

That is, by fixing a portion of the core around which the rolled material is wound to the side plate using an adhesive, the rolled material will not rotate due to vibrations during transportation and will not loosen. In addition, when loading a magazine into the Y magazine loading section, by pulling out the tip of the roll-shaped material slightly in advance and peeling off the adhesive part, the core can rotate freely and the roll-shaped material can be pulled out for a predetermined length. can.

In addition, adhesive tape, adhesive glue, etc. are mentioned as an adhesive material in this invention. It is preferable to use a slippery adhesive containing silicone.

Further, in the present invention, the roll-shaped material refers to a recording material such as a silver halide photosensitive material, a polymerizable photosensitive material, a heat-sensitive material, an image-receiving material, a pressure-sensitive recording material, etc., which is wound around a core. In particular, the present invention is effective for recording materials such as photosensitive materials using photosensitive capsules such as photopolymerizable photodepolymerizable capsules and silver halide-containing capsules.

(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 of cardboard or the like bent into a rectangular tube 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.
A hub 5 is provided for pivotally supporting the.

Therefore, when the winding core 3 wrapped with the photosensitive material 4 is engaged with the hub 5, a predetermined amount of adhesive 6 is applied to the portion where the end of the winding core 3 engages with the hub 5.

The adhesive portion can be peeled off by pulling out the photosensitive material 4 from the magazine.

Here, the location where the adhesive 6 is applied is not limited to the outer circular surface of the end portion of the winding core 3, and may be applied to the end face of the winding core 3, for example.

Furthermore, when the magazine is loaded into the image forming apparatus, the adhesive part must be peeled off by pulling out the tip of the photosensitive material with a force of, for example, about 1 kgf, so the amount of adhesive 6 applied must be the minimum necessary. It is preferable that a small amount be applied to the lower side of the winding core 3, but it may be applied to multiple locations if necessary.

FIG. 2 is a partial sectional view showing another embodiment of the magazine for rolled materials of the present invention.

The winding core 3 has a thin top paper 7 wrapped around it and a photosensitive material 4 wrapped around it, and the end portion of the core 3 that engages with the hub 5 is fixed with an adhesive deso 8.

Therefore, when loading the magazine into the image forming device,
By pulling out the tip of the photosensitive material 4 with a force of, for example, about 1 kg f, the upper paper 7 that engages with the hub 5 is torn, and the core 3 around which the photosensitive material 4 is wound becomes rotatable. Further, the top sticker 7 does not necessarily need to be wrapped around the entire core 3, and may be wrapped only around the hub engaging portion. Alternatively, the top sticker 7 may be pasted on one end surface of the core 3 and adhered to the adhesive tape 8 provided on the inner wall of the hub 5 facing thereto. In this case, by placing the magazine vertically so that the fixed side of the core 3 is on top, the top sticker 7 will be torn and the core 3 will be
is rotatable.

FIG. 3 is a partial sectional view showing another embodiment of the magazine for rolled materials of the present invention. Circumferential notches 9 are provided at both ends of the core 3 on which the photosensitive material 4 is wound, and the ends of the core outside the notches 9 are fixed to the hub 5 with an adhesive 6. However, the notch 9 is arranged so as to be located inside the hub 5 when engaged with the hub 5.

Therefore, when loading the magazine into the image forming device,
The notch 9 is broken by pulling out the tip of the photosensitive material 4 with a force of, for example, about 1 kg f, so the photosensitive material 4
The winding core 3 wound with is rotatable.

Note that in the embodiments of the present invention described above, adhesives such as adhesives and adhesive tapes are used, but the present invention is not limited thereto, and other adhesives may also be used. Further, the photosensitive material wound around the core is not limited to this, and other roll-shaped materials can also be used.

(Effects of the Invention) According to the present invention, by fixing a part of the core around which the rolled material is wound to the side plate with an adhesive, the rolled material rotates due to vibration during transportation, causing the winding to loosen. Therefore, scratches caused by loosening of the winding between the magazine and the photosensitive material, scratches between the photosensitive materials, etc., can be prevented, and good images can be obtained.
