Abstract

A magazine for containing a plurality of film cartridges and a method of using same. The magazine comprising at least one storage disk having a plurality of sleeves defining passages at both ends for retaining at least one of the film cartridges between the open ends. The magazine having a shutter mechanism disposed adjacent to at least one end of the at least one storage disk. The shutter mechanism comprising a first dispensing disk having a first access opening and a first central axis of rotation, and a second dispensing disk associated with and adjacent to the first dispensing disk. The second dispensing disk having a central axis of rotation in co-alignment with the first central axis and a second access opening. The second access opening being positioned on the second dispensing disk such that when the first and/or second dispensing disk is rotated about the central axis of rotation, the second access opening of the second dispensing disk is capable of aligning up with the first access opening of the first dispensing disk. A spring is provided for biasing the first and second dispensing disks about the first and second central axis of rotation such that the access openings of the first and second dispensing disks can be moved between an aligned position and non-aligned position.

Claims

1. A magazine for containing a plurality of film cartridges, said magazine comprising at least one storage disk having a plurality of sleeves defining passages at both ends for retaining at least one of the film cartridges between said open ends, said magazine having an shutter mechanism disposed adjacent at least one of said at least one storage disk, said shutter mechanism comprising a first dispensing disk having a first access opening and a first central axis of rotation, and a second dispensing disk associated with and adjacent to the first dispensing disk, said second dispensing disk having a central axis of rotation in co-alignment with said first central axis and a second access opening, the second access opening being positioned on said second dispensing disk such that when said first and/or second dispensing disk is rotated about said central axis of rotation, said second access opening of said second dispensing disk is capable of aligning up with said first access opening of said first dispensing disk;

and

means for biasing said first and second dispensing disks about said first and second central axis of rotation such that the access openings of said first and second dispensing disks can be moved between an aligned position and nonaligned position.

2. A magazine according to claim 1 wherein said biasing means for biasing said first and second dispensing disks for rotation about said central axis comprises at least one spring member having one end secured to said first dispensing disk and the other end secured to the second dispensing disk such that a circumferential biasing force is provided between said first and second disk.

3. A magazine according to claim 2 wherein there is provided a pair of spring members for biasing said first and second dispensing disks apart.

4. A magazine according to claim 1 wherein said first and second disks are provided with means for allowing rotating said first and second disks between said aligned and nonaligned positions.

5. A magazine according to claim 4 wherein said means for allowing rotating of said first and/or second dispensing disks in opposite circumferential directions comprises a pair of slots associated with each of said first and second dispensing disks.

6. A magazine according to claim 1 further comprising locking means for locking said first and second disk and said adjacent storage disk together.

7. A magazine according to claim 6 wherein said locking means comprises an axial extending locking slot in each of said dispensing disks positioned such that when the access opening in said first dispensing disk is aligned with the access opening in said second disk, said axial locking slots in each of said dispensing disks are also aligned.

8. A magazine according to claim 1 further comprising means for defining said aligned and nonaligned positions.

9. A magazine according to claim 7 wherein there is provided an circumferentially extending slot in each of said first and second dispensing disks and a mating projection in with each, of said first and second dispensing disks designed to engage the aligning slot in the other dispensing disk, said projection and slot being configured so as to define the aligned and non-aligned positions.

10. A magazine according to claim 9 wherein said projection prevents cartridges from entering the access opening in said dispensing disks.

11. A magazine according to claim 1 wherein said first disk is positioned such that said first access opening is positioned adjacent said sleeves in said storage disk.

12. A method of dispensing or inserting film cartridges into a film cartridge magazine, said magazine comprising at least one storage disk having a plurality of sleeves defining passages at both ends for retaining at least one of the film cartridges between said open ends, said magazine having a shutter mechanism disposed adjacent at least one of said at least one storage disk, said shutter mechanism comprising a first dispensing disk having a first access opening and a first central axis of rotation, and a second dispensing disk associated with and adjacent to the first dispensing disk, said second dispensing disk having a central axis of rotation in co-alignment with said first central axis and a second access opening, the second access opening being positioned on said second dispensing disk such that when said first and/or second dispensing disk is rotated about said central axis of rotation, said second access opening of said second dispensing disk is capable of aligning up with said first access opening of said first dispensing disk;

and

means for biasing said first and second dispensing disks about said first and second central axis of rotation such that the access openings of said first and second dispensing disks can be moved between an aligned position and non-aligned position, the method comprising the step of;

rotating said first and second dispensing disks such that the accessing openings are in co-alignment so that film cartridges can be inserted or removed from said sleeves.
