DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a cartridge storage container according to the present invention. The cartridge storage container 2 is mounted in a cylindrical case body 4 for storing a photographic film cartridge 3, a leaf spring 6 placed on a bottom surface 5 of the case body 4, and an opening 7 of the case body 4. It consists of a lid 8. The case body 4 and the lid 8 are molded of plastic to protect the stored photographic film cartridge 3 from moisture. In order to prevent the lid 8 attached to the case body 4 from coming off easily, a protrusion 9 is formed on the outer periphery of the fitting portion of the lid 8 and an opening 6 is formed.
A groove 10 is formed on the inner peripheral surface of the case body 4.
The leaf spring 6 is formed by bending a rectangular steel plate having a thickness of 0.1 mm into a dogleg shape, and is placed on the bottom surface 5 so that the central portion is lifted. Although the leaf spring 6 is made of a steel plate in this embodiment, tin plate, plastic, or the like may be used.

The operation of the cartridge storage container thus constructed will be described with reference to FIGS. 2 and 3. The photo film cartridge 3 is stored, and the lid 8 is attached to the case body 4
2, the leaf spring 6 is pressed by the photographic film cartridge 3 to be deformed as shown in the figure and to store energy. In this state, when the lid 8 is opened, the leaf spring 6 is restored and pushes the photographic film cartridge 3 upward as shown in FIG. The user can easily take out the upper portion of the photo film cartridge 3 by directly grasping it with his / her finger.

In order to directly grip the photo film cartridge 3 with a finger, a part of the photo film cartridge 3 is pushed out of the case body 4 by 5 mm to 20 mm.
Since it is necessary to project it, the leaf spring 6 has a displacement of 5 mm.
A thing of ~ 20 mm is used. By using a leaf spring 6 having a displacement of 10 to 15 mm, it is possible to more easily grip and to prevent the photographic film cartridge 3 from popping out when the lid 8 is opened. In addition, the leaf spring 6
Requires the photographic film cartridge 3 to be pushed up, so a pressing force of at least 20 g or more is required. If the pressing force is too large, the photographic film cartridge 3 will pop out with the lid 8 removed, so it is also necessary to keep the upper limit to about 1000 g. From this, the spring constant of the leaf spring 6 is about 1 g / mm to 200 g / mm, more preferably about 4 g / mm to 100 g / mm. In this embodiment, a leaf spring was used to push up the photographic film cartridge 3, but instead of this leaf spring, the coil spring 15 as shown in FIG. 4 and the apparent density 3 as shown in FIG.
The photographic film cartridge may be pushed up by using a 0 kg / m ² polyurethane sponge 16. Each of these embodiments can be manufactured at low cost due to its simple structure. For example, a cartridge storage container having a plurality of case bodies connected to each other, for example, a cartridge storage container 17 for storing three photographic film cartridges shown in FIG. Even if it is manufactured, the manufacturing cost does not increase.

FIG. 7 shows an embodiment of a cartridge storage container in which the bottom surface of the case body is provided with a spring property. In this cartridge storage container 20, the bottom surface 21 has a bowl-like shape, and the case body 22 is formed of a highly flexible resin. The bottom 21 of this cartridge storage container 20
The photo film cartridge 3 can be stored because it is deformed.

In the cartridge storage container 20 thus constructed, when the lid 8 is opened, the deformed bottom surface 21 is restored, and the photographic film cartridge 3 is pressed upward. By this pressing, the upper portion of the photographic film cartridge 3 is projected from the case body 22. Therefore, the user can directly grasp the upper portion of the photographic film cartridge 3 with his / her finger and can easily take it out.

FIG. 8 shows a pop-out prevention component used in a patrone storage container for preventing the photo film cartridge from popping out, and a photo film cartridge having locking portions on its side surfaces. The pop-out prevention component 31 is locked to a base plate 32 mounted on the bottom surface of the case main body, a pair of coil springs 33 provided on the upper surface of the base plate 32, and a locking portion 41 of a photographic film cartridge 40. Flexible locking claw 3
4, and a guide claw 35 which engages with the spool 42 of the photographic film cartridge 40 and guides the photographic film cartridge 40 urged by the coil spring 33 so as to be vertically pushed up.

In this cartridge storage container, the case body 3
The pop-out preventive component 31 is inserted into 0, and then inserted into the photographic film cartridge 40. During this insertion, the locking portion 41 contacts the locking claw 34, but when a force is applied to the locking claw 34, it deforms and retracts, so that the insertion of the photographic film cartridge 3 is not blocked. .. After that, the coil spring 33 is pressed and the spool 42 engages with the guide claw 35.

The operation of the cartridge storage container thus configured will be described. When the lid is opened, the coil spring 33 pushes the photographic film cartridge 40 upward. As a result, when the upper portion of the photographic film cartridge 40 protrudes from the case main body by a certain amount, the locking portion 41 abuts on the locking claw 34 and is prevented from popping out. After that, when the user holds the photographic film cartridge 3 with his finger and pulls it up, the locking claw 34 is deformed so as to be retracted, so that it can be taken out. In this embodiment, the locking claw 3
Although 4 is formed on the base plate 32, the same effect can be obtained by providing the locking claw 34 on the inner wall of the case body.

FIG. 9 shows a cartridge storage container having a strong locking force between the case body and the lid. This cartridge storage container 45 has a wrapping tab 47 formed on a lid 46,
The wrapping tab 47 presses the case body 48 from the outside of the case body 48. Therefore, the locking force between the lid 46 and the case body 48 becomes strong, and the lid 46 to which the spring pressure is applied can be reliably prevented from coming off the case body 48 due to vibration or the like.

In the cartridge storage container of the present invention described above, the leaf springs 6 and 15, the coil spring 15 and the sponge 1 are used.
Although the pop-out prevention component 31 and the like are placed on the bottom surface of the case body, they may be fixed using an adhesive.

[0016]

As described above, since the cartridge storage container of the present invention has a simple structure in which an elastic member is arranged in the case body and the bottom plate of the case body is provided with elasticity. The photographic film cartridge can be manufactured at low cost, and when the lid is opened, a part of the photographic film cartridge is projected from the case body, so that the photographic film cartridge can be directly grasped by the hand and reliably taken out. In a cartridge storage container in which a more flexible locking member is provided in the case main body, when a part of the photo film cartridge is projected from the case main body, the locking member locks the photo film cartridge, so that the projection film pops out from the case main body. Can be prevented.
