Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Applicability] The present invention relates to a magazine for rolled materials used for printing, printing, copying, etc.

[Technical background of the invention and its problems]

Conventionally, a magazine for a relatively wide rolled material used for printing, printing, copying, etc. has a rectangular cylindrical body part 1 and two parts that seal both ends of the body part 1, as shown in FIG. A roll-shaped material 3 is housed in a hollow interior formed by a cap 4, and the rolled material 3 is pulled out from a slot 2 extending along the axial direction of a winding core 5 at a corner of one side of the body portion 1. It's a magazine. (For example, Tokuko Sho 59
(Refer to Publication No. 36736) The rolled material 3 is stored in a state where the tip of the rolled material 3 is pulled out from the slot 2 of the magazine, and the tip is placed above the body of the magazine to prevent it from being rewound into the magazine. For example, it is fixed with tape 10. and,
For example, when loading a magazine into a magazine mounting section of an image forming apparatus, etc., the tape 10 is peeled off, and the tip of the rolled material 3 is caught, for example, by a conveying nip roller of the image forming apparatus, so that the rolled material 3 is A withdrawal is made.

It is known that when such a magazine for rolled materials is transported, the roll portion becomes loose due to large vibrations during transport. The occurrence of this winding loosening is caused by the fact that the rolled material 3 has no tension between the slot 2 and the outermost periphery of the rolled material 3 and is sagging, or that the tension gradually loosens due to vibration during transportation. Cause.

Then, as vibrations continue to be applied, this slack gradually propagates from the outermost periphery of the roll toward the inside, causing the roll to become loose. When this winding slack increases, the rolled material and the inner wall of the magazine rub against each other, causing damage to the surface of the rolled material. In addition, even if the looseness of the winding is not large, if the rolled materials rub against each other during transportation, or furthermore, if the rolled materials are pulled out of the magazine as described above, the winding will have to be tightened. This may cause scratches on the surface of the rolled material. The surface of roll-shaped materials normally used in image forming apparatuses and the like is often relatively easily scratched, and there is a problem in that these scratches appear on the final formed image.

As a countermeasure to this problem, Japanese Patent Application Laid-open Nos. 60-156058 and 5
No. 7-128333 As stated in each publication, the key (lock)
A method has been proposed in which the core of the roll is fixed to the core bearing of the end cap of the magazine using a cassette to prevent rotation of the core before the first use of the cassette. It is impossible to completely suppress vibrations at the outermost periphery of the roll-shaped material 3, and therefore, sufficient effects are not obtained.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems, and to provide a magazine for rolled materials that does not become loose due to vibration during transportation.

[Means for solving problems]

The present invention solves the above-mentioned problem by storing a rolled material wound around a core pivotally supported on the inner surface of the end cap in a hollow interior consisting of a cylindrical body part and two end caps sealing both ends of the body part. , a magazine for rolled material in which the rolled material is drawn out of the magazine from a slot extending along the core axis at a corner of one side of the body part, the outermost circumferential surface of the rolled material being pulled out with a pressing force that can be released at will. This is solved by equipping the body with a pressing member that suppresses this.

In other words, when the pressing member presses the outermost periphery of the rolled material, the bearing of the end camp of the winding core is moved in one direction, so that it does not move (furthermore, the pressing member and the outer periphery of the rolled material Frictional force is generated between the roll material and the outer periphery of the roll material, which prevents it from shifting and causing flapping and slack propagation.Therefore, the occurrence of loose winding is prevented.Furthermore, for example, when installed in an image recording device, , the force required to pull out the rolled material is reduced by releasing the pressing force.

Here, the roll-shaped material in the present invention refers to a recording material such as a 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 photopolymerizable capsules and photodepolymerizable capsules.

[Embodiment]

Embodiments of the present invention will be described using figures. FIG. 1 is a sectional view of one embodiment of the magazine for rolled materials of the present invention. A roll material 3 wound around a winding core 5 is housed in the center of a rectangular body portion 1 of the magazine for rolled material. The rolled material 3 is drawn out of the magazine by passing between the upper lip 6 and the lower lip 7 of the slot 2 extending in the axial direction of the core 5 at the corner of one side of the body part 1, and is attached to one side of the body part 1 with a tape 10. It is pasted. The pressing member 8 is inserted through the slot 2 and applies pressure to the rolled material 3 by coming into contact with the outer peripheral surface of the rolled material, the upper lip 6, and the lower lip 7. This pressure suppressed the rotation of the winding core 5 due to vibrations during transportation, and also prevented the spread of flapping and loosening of the rolled material 3, thereby preventing the occurrence of loosening of the winding.

FIG. 2 shows another embodiment of the present invention, in which the pressing member is divided into two parts inside the magazine, one pressing the inner wall of the body part 1 and the other pressing the outer peripheral surface of the rolled material. . Therefore, the pressing force was increased, and the rolled material could be held down more reliably.

FIG. 3 shows another embodiment of the present invention, in which the pressing member 8 has a bulge that abuts the inner wall of the body part 1 inside the magazine and abuts against the surface of the rolled material facing the inner wall. The roll-shaped material 3 is pressed against these two places and the bottom @7. Therefore, it was possible to reliably suppress the roll-shaped material.

The above-mentioned pressing member 8 is preferably made of a resilient material such as plastic. Moreover, FIG. 4 is a perspective view of the magazine for rolled materials, and shows an example of the position of the pressing member 8 and the width of the pressing member 8 in the core axis direction, which can be set arbitrarily. Furthermore, the pressing member 8 can also be assembled when assembling the magazine.

When this magazine for rolled material is used by being attached to an image recording device or the like, it is only necessary to pull out the above-mentioned pressing member 8 and attach it, which is very simple.

FIG. 5 shows another embodiment of the invention.

A press screw 9 is screwed through the body portion 1, and a press pad 9' is attached to the tip of the press screw 9. By screwing this press screw 9 inward into the magazine, it was possible to suppress the roll-shaped material 3 and prevent the occurrence of loosening of the roll.

In this embodiment, a rectangular magazine is taken as an example, but it is also applicable to a polygonal column type such as an octagonal column type, an octagonal column type, or a cylindrical type magazine.

[Effects of the present invention]

As mentioned above, by providing a pressing member in the magazine that presses the outermost surface of the rolled material, the winding core bearing prevents internal vibrations and propagation of flapping and loosening of the rolled material, and prevents loosening of the winding. This prevents the occurrence of scratches caused by the rolled materials rubbing against each other.
