Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a roll-shaped photographic material magazine for feeding a light-sensitive material to an exposed portion of a printer.

[0002]

2. Description of the Related Art Conventionally, when supplying a photographic light-sensitive material to a printer, the light-sensitive material is packed in a light-shielded box so that the light-sensitive material can be attached and detached without exposing the light-sensitive material in a bright room. This was done by pulling out the photosensitive material from a slit provided with a mechanism. As a photographic photosensitive material storage magazine used for such a purpose, the following a, b2 are conventionally used.
Kinds of things are used.

(A) A method in which a user stores a photosensitive material in a magazine attached to a device in a dark room and mounts it on a printer in a bright room (a reusable magazine).

(B) A method in which a photographic material manufacturer ships in a package stored in a magazine in advance, and the user mounts it in the printer as it is (disposable magazine).

Since the repeated use type magazine is costly and the user's labor for storage is complicated,
As a disposable magazine, for example, the one shown in FIG. 13 has been proposed. In this storage magazine, a photosensitive material wound around a bobbin (paper tube) 23 is stored in a box 22 composed of two outer shells 21 made of plastic.
23 Shaft of end plate 24 made of plastic that sticks to both ends
25 is rotatably supported by a bearing 26 formed in the outer shell 21.
This is described in French patent 2503400.

[0006]

However, in the conventional photosensitive material storage magazine, as shown in the example of FIG. 13, the light shielding box and the like are formed of plastic, and the structure itself is complicated. Therefore, the manufacturing cost was high and it could not be used as a disposable product.

Further, since it is made of plastic, there is a problem that the disposability after use is extremely poor.

The present invention is intended to solve the above-mentioned drawbacks, and has a light-shielding performance capable of withstanding a bright room loading, and
It is an object of the present invention to provide a disposable roll-shaped photosensitive material magazine that can reduce the withdrawal load of a photosensitive material having a large winding diameter and is inexpensive and easy to discard.

[0009]

This object is achieved by the following technical means.

A support having a spine plate made of paper and side plates made of paper connected to both edges of the spine plate and supporting both ends of a paper tube of a photosensitive material wound in a roll on the side plate. An inner body having a member is covered with a light-shielding box made of paper, and a drawer portion of the photosensitive material is formed by the bent portion of the spine plate and a lid portion of the light-shielding box. Is a roll-shaped photosensitive material magazine, which is provided with a light-shielding material.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of the present invention will be described with reference to the drawings.

As shown in the exploded perspective views of FIGS. 3 and 12, in the scroll of the roll-shaped photosensitive material 1 wound on the paper tube 23, inner diameter portions of both ends of the paper tube 23 are provided in the inner body 30. Side plates of 31,3
A disk member 40 as a supporting member rotatably attached to the shaft 2 by a shaft member 47 is fitted to and axially supported by the disk member 40.
The disc body 40 is formed by the shaft member 47 and the stopper member 47A.
It may be fixed to 0 and the paper tube 23 may be rotatable with respect to the disc body 40. And both side plates 31,3 of the inner body 30
Reference numeral 2 is a plate which is bent 90 ° on both sides of the spinal plate 33. Further, a light shielding material 2A is attached to the bent portions 35A and 35B of the spine plate 33 except the upper portion 35C. Also, the side plate 3 at the bottom
1, 32 and flaps 34A, 34B, 34C from the spinal plate 33 are provided by bending by 90 ° to provide the functions of reinforcement and light shielding.

As shown in the exploded perspective view of FIG. 1 and the partially broken perspective view of FIG.
And its inner lid 55 has its flaps 55A, 55B and 55C.
Is folded inward by 90 ° and closed. And flap 55
A light shielding material 2B is attached to the portion A and a part of the inner lid 55. Then, the flaps 34A, 34B at the bottom of the interior body 30,
Since 34C is placed on the bottom surface of the light shielding box 50, reinforcement and light shielding are strengthened.

The light shielding material 2A attached to the bent portions 35A and 35B of the interior body 30, the flap 55A of the light shielding box 50 and the light shielding material 2B attached to the inner lid 55 are part of FIG. 2 (b). Since the passage surface of the photosensitive material 1 is sandwiched as shown in the sectional view,
Along with smooth running, shading is stably achieved.

FIG. 4 is a sectional view showing a state in which the inner body 30 in which the scroll 1 of the roll-shaped photosensitive material is axially supported is housed in the light shielding box 50.

5 (a) is a developed perspective view of the inner body 30 in which the disk body 40 as a support member is rotatably supported by the side plates 31 and 32 by the shaft member 47. FIG. The inner body 30A shown in the exploded perspective view of FIG. 5 (b) is obtained by providing a front plate 33A also on the opposite surface of the inner wall 30 to reinforce the inner body 30.

Further, FIG. 7 shows a developed view of the interior body 30B in which the side plates 31 and 32 of the interior body 30 are reinforced by bending the side plates 31A and 32A, respectively.

Similarly, FIG. 8 shows a developed view of the interior body 30C in which the side plates 31, 32 of the interior body 30 are reinforced by two side plates 31A, 31B and 32A, 32B, respectively.

Since the interior members 30A, 30B, 30C are each made stronger than the interior member 30, they are suitable for accommodating a scroll of a larger roll-shaped photosensitive material. Further, by doing so, it is possible to drastically reduce the fogging of the photosensitive material due to the light leakage due to the ridgeline of the bent portion of the flap in the light-shielding box 50 or the pinhole generated from the corner.

Next, a development view of the light shielding box 50 is shown in FIG.

The spine 53, the front plate 53A and the side plate 51, which face the spine 53,
52 are arranged in a horizontal row, bottom flaps 54C and 54D are connected from the spines 53 and 51, respectively, and flaps 54A and 54B are arranged from the side plates 51 and 52, and each flap is bent at a dotted line. Since 54C and 54D compose one bottom plate and flaps 54A and 54B compose two bottom plates, the bottom plate of the light shielding box 50 has three layers as shown in the partial perspective view of FIG.

An inner lid 55 is provided as a flap above the front plate 53A, and the inner lid 55 is further provided with small flaps 55A, 55B,
55C is provided. The flap 55A is 180 as described above.
° Folded back to form the entrance and exit of the photosensitive material, and the light shielding material 2B
Is about to be pasted. Also, 55B and 55C serve as insertion portions when the inner lid is bent at a right angle at the dotted line. Further, the flap 56D is bent 90 ° along the dotted line with the side plate 52 to form an outer lid, and the small flap 56E is also bent 90 ° and fixed to the front plate 53A of the light shielding box with glue or the like. The small flap 52A of the side plate 52 is also attached to the surface of the front plate 53A of the light shielding box 50 to form the light shielding box 50.

The upper edge 53E of the spine plate 53 is lower than the upper edge 51E of the side plate 51 and the upper fold line 52E of the side plate 52, which is 90 ° at the bent portion 35A of the interior body 30. The height is almost equal to the height when folded. The height difference between the side plates 51 and 52 forms the entrance / exit of the photosensitive material, and a light shielding material is attached to this portion so that the light tight state can be maintained at all times.

Next, there are various kinds of roll-shaped photosensitive materials 1 having a wide width and a narrow width, and the sizes of the inner body 30 and the light shielding box 50 are changed and prepared in order to cope with such various kinds. Since it is difficult, in the present invention, at least the size of the light-shielding box remains fixed. This will be described with reference to the sectional views of FIGS. 9 (a) and 9 (b). That is, when the widths of the photosensitive material are W and w, the side plates of the inner body are selected so that T <t when the thickness is T for wide width and t for narrow width, and T <t. This can also be dealt with by stacking two side plates or three side plates, as described in the developed views of FIGS. 7 and 8.

However, in order to make it more universally applicable, as shown in the exploded sectional view of FIG. 10 (a) and the assembled sectional view of FIG. 10 (b), the disc 40 is used as the above-mentioned supporting member. A plurality of thin disks having the same thickness may be prepared to form a stacked disk, and the number of stacked layers corresponding to the width difference Ww of the photosensitive material may be determined.

In FIGS. 10 (a) and 10 (b), the interior body 3
The side plate of 0 adopts 32, 32A inside and outside. The side plates are left as they are, and the discs to be laminated are provided with a large number of discs 41B of small diameter and the same diameter and a disc 41A of large diameter, and the discs and side plates are concentric with each other. Member 4
Each disk is fastened by 7 and a stop member 47A and is rotatably provided around the shaft member 47. In this case a large diameter disc
41A is fitted on the inner diameter surface of the paper tube 23 of the rolled photosensitive material 1. Accordingly, even if the width of the rolled photosensitive material is various, by applying such a relatively simple member, it is possible to take a reliable and easy handling measure at low cost. Of course, the small-diameter disc may have the same size as the large-diameter disc. If the shaft member 47 and the inner diameters of the discs 41A and 41B with which the shaft member 47 is fitted are made to have a slippery friction coefficient and a small friction coefficient, a smooth operation of supplying the photosensitive material with a small drawing torque becomes possible. For example, as the shaft member 47, a sintered metal (oil-containing alloy) impregnated with a lubricity imparting agent is used.
Can also be used. Further, it is effective to impregnate and / or apply a small amount of silicon oil to the inner diameter portion of the disc body 40 or the shaft member.

The material of the shaft member 47 and the stopper member 47A may be ordinary metal or plastic other than the above-mentioned sintered metal (oil-containing alloy). Further, it is desirable that it has a light-shielding property, and in the case of plastic, a material having a high light-shielding property in which carbon or the like is blended is preferable.

The material of the disc body is preferably paper or plastic. Shading boxes for such magazines to be discarded 5
0, the main body of the inner body 30 is a paper material, which can be placed on the route of resource recovery and reuse, but if possible, metal or plastic of the shaft member 47 and the stop member 47A, cloth material such as the light shielding materials 2A, 2B In the case where the disc bodies 41A and 41B are made of plastic, and the disc bodies 41A and 41B are made of plastic, if they can be separated and collected, they can be reused with higher purity and easily and reliably. Therefore, it is very effective to make a perforation in the portion of the light shielding box 50 around the shaft member so that it can be easily separated,
In order to easily remove the light-shielding material, it is desirable that the inner edge portion of the entrance / exit of the photosensitive material is not adhered and can be peeled off to be peeled off. As the adhesive, hot melt, double-sided tape or the like can be used.
Even if there are perforations, the side plate of the interior body 30 and the light-shielding box 50
When the flap and the like have a double structure or a triple structure as described above, there is no fear of light leakage.

However, when a corrugated cardboard composed of paper on both sides and reinforcing paper between them is used as the paper material, it is preferable to make perforations only on the paper on one side.

As a result, the light can be shielded more reliably, and the removal of the shaft member portion or the like can be done easily and vividly with only one perforation.

In addition, it is desirable that the inner body 30 and the light shielding box 50 are black-painted or black paper is used in the portion facing the rolled photosensitive material.

Further, the disc body 40, the shaft member 47 as its mounting member, and the stopper member 47A are two parts, and the disassembly can be easily performed by removing these two parts. Even if the body 40 is not a paper product but a plastic or other material, the structure can be easily removed and separated.

The flap 54E of the outer lid 54D of the light shielding box 50 may be glued on the outside or may be inserted inside the outer box.

[0034]

The effects of the present invention can be summarized as follows.

(A) Since the base material is paper and the light shielding material and the disk body as the paper tube supporting member, the shaft member and the stopping member are also separable, it is possible to dispose of each material and You can effectively recycle and reuse.

(B) By reducing the friction of the disk body and the shaft member, the withdrawal load of the core portion of the photosensitive material having a large winding diameter can be reduced.

(C) A plurality of sizes (width sizes) can be supported by adjusting the number of stacked disc bodies. Also, the holding strength of the light-sensitive material can be obtained.

(D) Since it is composed of a light-shielding box as an inner body and an outer body, it has a small number of basic parts and is easy to manufacture.

(E) Since the upper and lower surfaces of the light shield have a folded structure, the side surface has a side surface of the interior body, and the bottom surface has a multilayer structure with the flap of the interior body, the light shielding property is improved and sufficient. Is becoming
