Abstract

PURPOSE:To prevent the loosening of winding of the rolled material and to obviate the generation of flaws in the rolled material before use by connecting the inner side of a winding core and an adhesive piece via the hole of a plate disposed between a side plate and the winding core and further releasing the connection by this adhesive piece at the time of drawing out the rolled material. CONSTITUTION:The plate P is provided between the side plate 2 and the winding core 3. The inner side of the core 3 and the surface on the side plate 2 side of the plate P are connected by the adhesive piece 6 via the hole of this plate P. The piece 6 maintains the adhered state of the core 3 and the plate P via the hole of the plate P until the rolled material 4 is drawn out and used. The connection of the core 3 and the plate P is easily released by the force of drawing out the material 4. The rotation of the rolled photosensitive material by the oscillation during transportation and the generation of the loosening of the winding are obviated and the rubbing flawing of the magazine and the rolled material, the rubbing flawing of the photosensitive materials to each other, etc., are prevented. The easy drawing out of the rolled material is possible.

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, relatively wide magazines for photosensitive rolls used for printing, printing, copying, etc., have a rectangular cylindrical body part made of cardboard or plastic, which is bent and formed. 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 photosensitive materials that draws out the photosensitive materials 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 made of 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 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 the magazine mounting section of an image forming apparatus, the tape is removed and the leading edge of the photosensitive material is gripped by, for example, a nip roller for conveying the image forming apparatus, thereby pulling out the photosensitive material. It will be done.

(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.

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 space between the side plate and the core is provided. A plate with holes at positions corresponding to the winding core (
P), and connect the inner side of the winding core and the plate (P) through the hole in the plate (P).
P) is connected by an adhesive piece, and further, when the rolled material is pulled out, the plate (P) has a shape and size that does not rotate, and the connection by the adhesive piece is released. achieved by a magazine for

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

FIG. 1 is a partial sectional view showing an embodiment of the magazine for rolled materials according to the 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.
It has a holding shaft 5 for pivotally supporting the.

Between the side plate 2 and the winding core 3, there is a plate (P) as shown in Fig. 2.
is provided, and the inside of the core 3 and the side surface of the plate (P) on the side plate 2 side are connected by an adhesive piece 6 through the hole in this plate (P), and even if the magazine is shaken during transportation, There is no possibility of loosening of the rolled material. In other words, the plate (P) is
This is a winding loosening prevention plate that prevents rotation of the winding core 3 connected by adhesive pieces 6 during transportation, and for this purpose, the plate (P)
The body itself has a shape and size that does not rotate within the body 1. Further, the above-mentioned shape and size of the plate (P) are such that when the rolled material 4 is pulled out from the slot (drawing port) 7, it is connected by the adhesive piece 6, as shown in FIG. 3 showing a perspective view of the magazine of the present invention. It also has the function of releasing the winding core 3 and allowing it to start rotating freely.

Preferably, the hole in the plate (P) is circular with a diameter equal to the inner diameter of the winding core 3. The thickness of the plate (P) is preferably about 0.5 to about 3 mm. The material of the plate (P) may be any material such as paper, plastic, wood, metal, etc.

The adhesive piece 6 maintains a state of adhesion to the winding core 3 and the plate (P) through the hole in the plate (P) until the rolled material 4 is pulled out and used. It is necessary that the connection between the winding core 3 and the plate (P) be easily released. For this purpose, for example, the winding core 3 of the adhesive strip 6
A method of creating a difference between the adhesive strength to the inside of the core and the adhesive strength to the plate (P) (using different types of adhesives, using adhesives with different adhesive strengths to the core and the plate (P), etc.) or rolled material A method of using an adhesive piece 6 that is cut between the winding core 3 and the plate (P), that is, near the hole in the plate (P) by the force of pulling out the adhesive piece 4. It is preferable to use an adhesive tape with eye-shaped through holes or an adhesive tape with a narrow cut portion). In particular, in the latter method of cutting the adhesive piece 6, since the cut adhesive piece 6 remains adhered to the inside of the winding core 3 and the plate (P), there is no problem in the subsequent drawing out of the rolled material 4. This is the preferred method.

The adhesive piece 6 may be made of any material as long as it satisfies the above-mentioned performance, but generally a low-adhesion tape made of various types of paper coated with an adhesive is desirable.

Although it is sufficient to use the adhesive piece 6 at one location, it may be used at multiple locations if necessary.

Further, the winding loosening prevention means using the plate (P) and the adhesive piece 6 can achieve the purpose if applied to one side plate 2, but it may be applied to both sides.

The winding loosening prevention means of the present invention has a plate (
P) and the adhesive piece 6, there is no need to change the magazine body, and there is also the advantage that there is no need to make a new metal one.

The roll material 4 may have a photosensitive composition, such as a silver halide emulsion layer, 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, before sealing the end of the magazine with the side plate 2,
By simply connecting the core 3 and the plate (P) with the adhesive piece 6 as described above, the rolled photosensitive material will not rotate due to vibrations during transportation and will not become loose. 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.
