Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an improvement in a photographic sheet film supply magazine that unseals and sets a plurality of sheets of non-photosensitive sheet film sealed in a bright room. be.

[Conventional technology]

Conventionally, when loading unexposed sheet film into a magazine used in an X-ray imaging device, for example, the unexposed sheet film and the magazine were brought into a darkroom, and the operator manually inserted the unexposed sheet film into the packaging bag. It was necessary to resort to the usual method of opening the package, taking out the unexposed sheet film, and loading it into a magazine.

However, this loading method not only requires darkroom equipment, but also requires time and effort to operate.
In addition, there were drawbacks such as scratches on the film surface. For this reason, by enclosing multiple sheets of film in a flexible light-shielding bag, inserting this into a magazine, sealing the magazine, and then taking out the flexible light-shielding bag from the magazine, it is possible to store it in a bright room. A photographic sheet film supply magazine is provided that is loaded into the magazine.

However, with this type of film supply magazine, when the flexible light-shielding bag is stored in the magazine, the flexible light-shielding bag is large and floats up, causing the bag to tear when closing the top lid, or to cover the bag. The flexible light-shielding bag had to be carefully stored in the magazine because there was a risk that the light-shielding bag would not come out and become sticky.

[Purpose of invention]

The purpose of this invention is to suppress the lifting of the flexible light-shielding bag inside the magazine, and to prevent the bag from tearing, covering, or becoming impossible to remove when closing the top cover. A photographic sheet that has a claw part and also forms a part of the wall of an opening groove for taking out a flexible light-shielding bag, so that sheet film can be easily loaded into a magazine even in a bright room. Provides a film supply magazine.

[Structure of the idea]

In order to achieve the above-mentioned object, the present invention includes a storage section that is composed of an upper lid section and a main body section and that stores a plurality of sheet films sealed in a flexible light-shielding bag; In the photographic sheet film supply magazine, the photographic sheet film supply magazine has an opening groove that extends the pulling end of the main body, and a light shielding member that maintains the storage section in a dark room state when the upper lid is closed in the main body. The upper lid is closed to the main body, and one side of the wall forming the opening groove is formed by a pair of claws provided on the main body and a part of the wall of the upper lid. configured,
The other three sides are a setting part for setting the pulling end of the flexible light-shielding bag provided on the main body part;
It is characterized by comprising walls on both sides of the main body rising from the set portion.

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on the drawings.

FIGS. 1 and 2 are perspective views and cross-sectional front views of a plurality of non-photosensitive sheet films used in the present invention, which are sealed and packaged.

The non-photosensitive sheet film 1 is covered with a film protection member 2 and further wrapped in a slippery flexible light-shielding bag 3 made of black polyethylene resin or the like.

This flexible light-shielding bag 3 is larger than the sheet film 1 and the film protection member 2 and has a size that allows both ends to be folded back sufficiently, and is preferably formed in a tube shape. Both ends, namely the tension end 3a and the cut end 3
B is sealed and packaged.

FIG. 3 is a perspective view showing the photographic sheet film supply magazine of the present invention opened and a flexible light-shielding bag set therein.

The magazine 4 has a box-like shape large enough to accommodate the flexible light-shielding bag 3, and is composed of a main body part 5 and an upper lid part 6. This upper lid part 6 is connected to the rear end part 7 of the main body part 5 and is provided so as to be openable and closable.
A shutter 9 is provided which is opened and closed by a plunger 8. The front wall 10 of the main body part 5 is provided with a pair of claws 11 on the left and right sides to prevent the flexible light-shielding bag 3 from lifting up when it is set. An opening groove 12 is formed through which the tension end 3a of No. 3 passes. That is, the opening groove 12
is constructed with the upper lid part 6 closed on the main body part 5, and one side of the wall forming the opening groove 12 is connected to the pair of claw parts 11, 11 provided on the main body part 5 and the upper lid part 6. It consists of part of the wall of
The side is connected to the flexible light-shielding bag 3 provided on the main body 5.
setting part 5b for setting the tension end 3a of
and wall portions 5c on both sides of the front wall of the main body portion rising from the set portion 5b. still,
This opening groove 12 has a plurality of rollers 1 serving as light shielding members.
3a, 13b, and 13c.
Then, turn the UP mark 14 of the flexible light-shielding bag 3 upwards,
The tension end 3a of the flexible light-shielding bag 3 is connected to the front wall 1 of the main body 5.
0, the flexible light shielding bag 3 is set in the storage part 5a formed in the main body part 5, and the cut end 3b is extended to the outside from the closed shutter 9. Note that the claw portion 11 is not limited to being provided integrally with the front wall 10 of the main body portion 5, but the claw portion 11 may be provided on the front wall portion as a separate member as shown in FIG.

FIG. 5 is a perspective view showing the top cover of the photographic sheet film supply magazine in a closed state, and FIG. 6 is a sectional view thereof, showing the flexible light-shielding bag 3 extending outside through the shutter 9 The cut end 3b is pulled out and the root is cut off with a cutter 15. Next, when the tension end 3a of the flexible light-shielding bag 3 is pulled in the direction A, it is squeezed by the clamping rollers 16, and then the rollers 13a,
While meandering between 13b and 13c, the film is pulled out while maintaining light shielding, and the loading of the film is completed.
That is, the sheet film 1 sandwiched between the film protection members 2 remains in the photographic sheet film supply magazine 4.

[Effect of idea]

According to the photographic sheet film supply magazine of the present invention, a claw part for preventing the flexible light-shielding bag from floating is provided on the front wall of the magazine body, and the claw part is used to remove the flexible light-shielding bag. By forming a part of the wall of the opening groove, it suppresses the floating of the flexible light-shielding bag when it is stored in the magazine, and prevents the bag from tearing, covering, or falling out when the top lid is closed. Since it is possible to prevent the sheet film from becoming loose, the sheet film can be easily loaded into the magazine even in a bright room.
