Abstract

PURPOSE:To prevent generation of flaws in a rolled material by providing deflecting parts to the hub bottom parts of side plates and providing detaining parts which freely releasably detain a winding core by overhanging into the winding core to the deflecting parts so that the winding core is detained and released to an from the deflecting parts in the deflecting direction thereof. CONSTITUTION:The side plates 2 have the deflecting parts 6 in the hub 5 bottom part and the deflecting parts 6 have the detaining parts 8 which freely releasably detain the winding core 3 by overhanging into the winding core 3. The winding core 3 is detained and released to and from the deflecting parts 6 in the deflecting direction thereof. More specifically, the detaining parts 8 overhanging into the winding core 3 from the deflecting parts 6 energize the inside surface of the winding core 3 wound with a rolled material 4 outward in the radial direction and fix the same to the hub 5 by the elastic force thereof, by which rotation of the material 4 by oscillation during transport and the consequent generation of loose winding are obviated. Galling of the magazine and the rolled material or the rolled materials against each other by the loose winding is thereby prevented.

Description

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

(Prior Art) Conventionally, magazines for relatively wide roll-shaped photosensitive materials used for printing, printing, copying, etc. have, for example, a rectangular cylindrical body part made by bending a body plate made of cardboard or plastic. 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 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 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.

(Problems 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. 128333, 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 obtained.

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 the magazine for rolled materials, which accommodates loaded rolled materials and draws the rolled materials out of the cylindrical body from a slot extending parallel to the winding core axis of the body, the side plate has a flexible portion at the bottom of the hub. The flexible portion has a locking portion that protrudes into the core and releasably locks the core, and the core is locked and released in accordance with the direction of deflection of the flexible portion. This is achieved by a magazine for rolled materials characterized by:

In other words, the locking part that protrudes from the flexible part into the core uses its elastic force to force the inner surface of the core around which the rolled material is wound radially outward and fixes it to the hub during transportation. The roll of material will not rotate due to vibrations and loosening of the roll will occur. Furthermore, when loading a magazine into the magazine loading section, by changing the deflection direction of the flexible section, the biasing force of the locking section against the winding core is released, and the winding core can freely rotate and hold the rolled material in a predetermined position. The length can be pulled out.

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 capsules and photodepolymerizable capsules containing silver halide.

(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 body plate made of cardboard or the like into a rectangular cylindrical shape, and side plates 2 that close 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 for pivotally supporting the winding core 3 and a flexible portion 6 having a lip 8 for locking and releasing the protruding winding core 3 are provided inside the magazine.

Here, the flexible portion 6 is connected to the hinge portion 10 as shown in FIG.
It consists of a curved portion 7 whose deflection direction changes depending on the bending direction, a lip 8 projecting inward from the curved portion 7, and a handle 9 provided on the outer surface of the magazine of the curved portion 7. Preferably, the hinge portion 10 is provided with a groove, or the curved portion 7 is formed to be thinner than the other end plate portions, so that the flexible portion 6 can be easily deformed.

When the curved portion 7 is in a bent state projecting outward from the magazine, the lip 8 protrudes toward the center axis of the hub 5.

Further, when the curved portion 7 is in a convex deflection state inward of the magazine,
The lip 8 protrudes in the radial direction of the hub 5 as shown in FIG.

Therefore, when the core 3 wrapped with the photosensitive material 4 is engaged with the hub 5, the curved portion 7 engages with the magazine in a convexly bent state. Then, by pressing the handle 9 inward of the magazine and bending the curved portion 7 in a convex manner inward of the magazine as shown in FIG. 3, the lip 8 attaches the core 3 outward in the radial direction. Since the inner wall of the force winding core 3 is locked, the winding core 3 is fixed to the side plate 2.

When loading the magazine into the magazine loading section, the handle 9 is pulled outward from the magazine and the curved section 7 is bent outward, so that the lip 8 is attached to the inner wall of the core 3. Since the lock is released, the winding core 3 becomes freely rotatable and the rolled material can be pulled out for a predetermined length.

In the above embodiment, the flexible portion 6 and the side plate 2 are made of the same member, but the present invention is not limited to this, and they may be made of different members and assembled. Further, a plurality of lips 8 may be arranged concentrically on the hub 5.

Further, the photosensitive material wrapped 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, the locking portion protruding from the flexible portion provided on the hub of the side plate into the core uses its elastic force to urge the core around which the rolled material is wound. Since it can be easily fixed to the hub, the rolled material will not rotate and loosen due to vibration during transportation. Therefore, it is possible to prevent scratches caused by loosening of the winding between the magazine and the rolled material, and scratches caused by rubbing between the rolled materials.
