Abstract

PURPOSE:To obviate the generation of the looseness in the winding of a photosensitive band material by oscillations during transportation, etc., by fixing the winding core of the photosensitive band material to a container body or cover by a fixing means and easily releasing the fixing so that the winding core is made freely rotatable. CONSTITUTION:A slot piece 15 is fixed to the container body 11 and a rotating core 6 is fixed into a fixing hole 5 via a circular hole 9 by an adhesive agent 10 packed therein while a cup part 7 is held covered on a core supporting shaft 4. The front end of the photosensitive band material 11 is then emerged from the slit 16 and the winding core 12 is inserted in this state to the rotating core 6 while the core is held press fitted. A cover 13 is fitted to the container body 1 and the body 1 is hermetically sealed, by which the container for the photosensitive band material is completed. The winding core 12 and the rotating core 6 rotates when the photosensitive band material 11 is drawn out at the time of use. The adhesive agent 10 is cut on the boundary surface of the rotating core 6 and the core supporting shaft 4. The core 6 can, therefore, rotate around the core supporting shaft 4 as a central axis without resistance. The looseness in the winding of the photosensitive band material is prevented in this way by the extremely simple structure.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention provides a photosensitive strip containing a rolled-up photosensitive strip.
This invention relates to a photosensitive strip container consisting of two members: a container body and a cover.

[Prior art]

A photosensitive strip material wound into a roll, such as microfilm, computer microfilm, and computer phototypesetting film, is stored in a photosensitive strip container consisting of a container body and a cover that fits into the container body. It is installed in exposure equipment such as printers. If such a photosensitive strip container does not have a means to prevent the photosensitive strip from unwinding, the photosensitive strip may easily loosen, and there may be resistance when pulling the photosensitive strip from the slot. became large and often slipped on printers, etc. (US P 4,272.03
No. 5).

Therefore, various means have been proposed to prevent the photosensitive strip from unwinding.
No. 0), there was a means to expose the core into which the winding core fits to the outside and fix this core from the outside (U.S.P.
No. 4,756,418).

Note that a photosensitive strip container consisting of three members, a body and side plates, uses a rotating core and has a means for temporarily fixing the core to the sides in a separable manner using a fixing means (Japanese Unexamined Patent Publication No. 1-121852). ).

[Problem to be solved by the invention]

The above-mentioned means for pasting between the leaders requires a complicated assembly process, and the means for fixing the cores by exposing them to the outside has a problem in light-shielding properties.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and provide a photosensitive strip container that has an extremely simple structure and can prevent the photosensitive strip from loosening.

[Means to solve the problem]

The present invention has been made to achieve the above object, and is a container comprising a container body formed with a slot from which a photosensitive strip is pulled out, and a cover that seals a side opening of the container body. The present invention is characterized in that one of the container body or the cover is provided with a fixing means for fixing the core of the photosensitive strip material to the container body or the cover in a separable manner.

The fixing means detachably fixes the core of the photosensitive strip to the container body or cover. This fixing means may be of any type as long as it can be released from the fixed state by pulling out the photosensitive strip. For example, the core may be directly fixed to the container body or cover, or it may be a rotating type that loosely fits into the core support shaft. It may be fixed indirectly by scratching the core.

The rotating core has a fixed core, and the core is fixed to the container body or cover so that it does not rotate before use, such as during transportation, and is separated from the container body or cover when used in a printer, etc. This allows the winding core to rotate freely. The rotating core and the winding core only need to rotate together when rotating, and there is no particular restriction on the means for connecting them. For example, in the case of a cylindrical core, there is a method in which the rotating core is press-fitted into the core and fixed.

The core support shaft rotatably supports the rotating core.
Various methods can be used for supporting it, for example, it may be supported inside or outside the rotating core. Further, the core support shaft may be directly integrated with the container body or the cover, or may be fixedly provided via another member.

As the fixing means, curable adhesives such as thermosetting adhesives, thermoplastic adhesives, and hot melt adhesives can be used, and among these, hot melt adhesives are preferred.

Further, the pin may be inserted into the container body or the cover and the rotating core, or a double-sided adhesive tape may be used for fixation, and various other fixing methods may be used.

The region where the container main body or cover and the winding core or rotating core are fixed by the fixing means is preferable because the peripheral edge portion remote from the center of rotation can be separated by a short distance from which the photosensitive strip is pulled out.

The initial resistance when pulling out the photosensitive strip is adjusted by the sheared area, etc. in the case of resin, and the total cutting area, etc. in the case of pins.

There are no particular restrictions on the shape, material, etc. of the container body and the cover, and since they are disposable in principle, it is preferable that they can be provided at low cost, and therefore it is preferable that they be simple and easy to construct and manufacture. In addition, there are no particular restrictions on the shape or structure of the slot in the container body;
It suffices as long as it can ensure the same and the withdrawal resistance.

Photosensitive strip materials include color photographic paper, photoresist, computer microfilm, computer typesetting photographic paper, and JI
It includes all strip-shaped photosensitive strips such as S135 type photographic film (Leica film).

The light-shielding container includes all containers having a structure in which a photosensitive strip wound in a roll around a core is stored and the photosensitive strip is pulled out from a slot. Examples include light-shielding containers for computer microfilm, computer typesetting photographic paper, color photographic paper, and JIS 135 type photographic film cartridges.

[Effect]

In the photosensitive strip container of the present invention, when not in use such as during transportation, the fixing means fixes the rotating core to the container body or cover, thereby fixing the core fixed to the rotating core to the container body or cover. Furthermore, during use, the rotating core is released from the container body or the cover by releasing the fixing means, and is made freely rotatable around the core support shaft, thereby making the winding core rotatable.
