Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a magazine for storing photographic materials used when supplying photographic materials to a printer or the like.

[Conventional technology]

Generally, in order to supply photographic material to a printer, a magazine containing the photographic material in a light-tight manner is loaded, and the photographic material is pulled out from the outlet port of the magazine and supplied to the printer.

Conventionally, such photosensitive material storage magazines have been made of cardboard boxes made by assembling cardboard to make them inexpensive and disposable.The corners of these cardboard boxes have pinholes to block light. In order to ensure safety, light-shielding tape or light-shielding bond was attached (Japanese Patent Laid-Open No. 62-240958, Utility Model Laid-Open No. 63-15).
3255, etc.).

[Problem to be solved by the invention]

In the above-mentioned conventional photographic material storage magazine, in order to ensure the light-shielding properties of the corners, it is necessary to provide light-shielding tape, light-shielding bond, etc. at each corner. The work was troublesome because the cardboard box had to be assembled.

In addition, since light-shielding properties must be ensured by the cardboard itself, the cardboard box must be made of multiple layers of thick cardboard, requiring many steps to produce the cardboard box and making it expensive.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and to provide a magazine for storing photographic materials that can be produced extremely easily and inexpensively, and can completely ensure light-shielding properties.

[Means to solve the problem]

The present invention has been made to achieve the above, and includes a magazine that rotatably supports a roll of photosensitive material and that can be freely drawn out from an exit port. a rectangular cylinder consisting of a flap provided on the rectangular cylinder and a port piece provided at the end of the flat plate; a light shielding sheet provided from the flat plate of the rectangular cylinder to at least a part of the flap; 1; the rectangular cylinder; It is characterized by comprising a side plate fixed to the flap of the body.

The rectangular cylinder surrounds the four sides of the photographic light-sensitive material in a light-shielding manner and is made of paper, but as long as the light-shielding properties can be ensured in combination with the light-shielding sheet, paper as thin as possible can be used.

This rectangular cylindrical body consists of a flat plate part on four continuous sides, flaps provided on both sides of the flat plate part, and port pieces provided at the ends of the flat plate part. When the rectangular cylinder is made of corrugated cardboard, the continuous direction of the flat plate part and the port piece should match the direction of the corrugated corrugated corrugation, that is, the bending line of the flat plate part and the port piece should be perpendicular to the corrugated line direction, and the flat plate part and the flap should be aligned. It is preferable that the fold line is parallel to the line direction of the step. By doing so, the accuracy of the outlet port can be improved.

Further, it is preferable that the bending line between the flat plate part and the port piece is formed into an outwardly protruding arc shape with a radius of about 750 mm to 1,500 mm, so that the flat plate part located at the upper part of the exit boat part bulges outward. Even in such cases, the opening of the exit boat portion does not become large and light shielding properties can be ensured.

The light-shielding sheet blocks light from the four sides and corners of the rectangular cylinder, and various sheets such as polyethylene resin film added with a light-shielding substance such as carbon black, light-shielding paper, etc. are used. This light-shielding sheet covers the entire surface of the flat plate portion of the rectangular cylinder and at least a portion of the flap. The surface of the light-shielding sheet that covers the flap only needs to be a surface that can shield pinholes generated at the corners.

To provide the light-shielding sheet on the rectangular cylinder, a portion or the entire surface thereof is adhered to the flat plate portion using an adhesive, double-sided tape, or the like.

The side plate blocks light from the two open sides of the rectangular cylinder.
As long as light-shielding properties can be ensured, for example, it may be made of cardboard only, or it may be provided with a light-shielding sheet like the rectangular cylinder.Also, even if the side plate is a simple plate-like body, it may be made of a roll. It is also possible to use a photographic light-sensitive material with a rotatably supported shaft integrally provided therein.

[Effect]

In the photographic material storage magazine of the present invention, the rectangular cylinder and the light-shielding sheet shield four sides of the photographic material, and the side plates cover the other two sides.
The surface is light-shielded, and the light-shielding sheet also ensures light-shielding at the corners.

In addition, since the box-shaped body is formed by two members, the rectangular cylinder and the side plate, it simplifies the assembly work, and allows various shapes to be cut out from sheets of paper, making it economical and with good yield. We are trying to make it possible to adopt a certain mode.
