Abstract

Abstract A magazine for photographic film is provided with two spacedparallel external walls which define a groove serving to receive, with certain clearance, an elongated rib provided in the chamber of the camera housing. Such clearance is reduced, when the magazine is fully inserted into the chamber, by one or more projections which are provided on the rib and engage the adjoining wall or walls of the magazine. The projection or projections ensure that the claws of the rotary coupling member of the film-transporting mechanism in the housing properly engage the claws on the takeup reel of the magazine which is accommodated in the chamber.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 103 words
In a photographic camera, a combination comprising a housing having a chamber; a film-containing magazine removably accommodated in said chamber; a first guide portion having two walls defining therebetween an elongated groove; a second guide portion including an elongated rib, one of said guide portions being provided on said housing and the other guide portion being provided on said magazine and said rib extending with clearance into said groove to locate said magazine in said chamber with limited clearance; and a projection provided on one of said guide portions and abutting against the other guide portion in said groove to reduce said clearance.
Claim 2
Dependent Claim 103 words
In a photographic camera, a combination comprising a housing having a chamber; a film-containing magazine removably accommodated in said chamber; a first guide portion having two walls defining therebetween an elongated groove; a second guide portion including an elongated rib, one of said guide portions being provided on said housing and the other guide portion being provided on said magazine and said rib extending with clearance into said groove to locate said magazine in said chamber with limited clearance; and a projection provided on one of said guide portions and abutting against the other guide portion in said groove to reduce said clearance.
Claim 3
Dependent Claim 34 words
A combination as defined in claim 1, further comprising a second projection provided on one of said guide portions and abutting against the other guide portion in said groove to further reduce said clearance.
Claim 4
Dependent Claim 63 words
A combination as defined in claim 1, further comprising a film-collecting reel rotatably mounted in said magazine and having a first coupling member accessible from the exterior of said magazine, and a complementary second coupling member rotatably mounted in said housing and engaging with said first coupling member so that said reel is rotated in response to rotation of said second coupling member.
Claim 5
Dependent Claim 49 words
A combination as defined in claim 3, wherein the guide portion which is provided with said projection has a first end nearer to and a second end more distant from said reel, said projection being nearer to the first than to the second end of said last-mentioned guide portion.
Claim 6
Dependent Claim 20 words
A combination as defined in claim 3, wherein said rib makes an oblique angle with the axis of said reel.
Claim 7
Dependent Claim 26 words
A combination as defined in claim 4, wherein said second guide portion is provided on said housing and wherein said projection is provided on said rib.
Claim 8
Dependent Claim 19 words
A combination as defined in claim 6, wherein said projection extends upwardly in the normal position of the camera.
Claim 9
Dependent Claim 45 words
A combination as defined in claim 1, further comprising a second projection provided on one of said guide portions and abutting against the other guide portion in said groove, said projections being remote from each other as considered in the longitudinal direction of said rib.
Claim 10
Dependent Claim 261 words
In a photographic camera, a combination comprising a housing having a chamber; a film-containing magazine removably accommodated in said chamber; a first guide portion having two walls defining therebetween an elongated groove; a second guide portion including an elongated rib, one of said guide portions being provided on said housing adjacent to said magazine, said rib extending with clearance into said groove to locate said magazine in said chamber with limited clearance; a first projection provided on one of said guide portions and abutting against the other guide portion in said groove to reduce said clearance; and a second projection provided on one of said guide portions and abutting against the other guide portion in said groove to further reduce said clearance; said projections being located at the opposite sides of said rib. 10 In a photographic camera, a combination comprising a housing having a chamber; a film-containing magazine removably accommodated in said chamber; a first guide portion having two walls defining therebetween an elongated groove; a second guide portion including an elongated rib, one of said guide portions being provided on said housing adjacent to said chamber and the other guide portion being provided on said magazine, said rib extending with clearance into said groove to locate said magazine in said chamber with limited clearance; and a projection provided on one of said guide portions and abutting against the other guide portion in said groove to reduce said clearance, the height of said projection approximating half the difference between the width of said groove and tHe width of said rib.
Claim 11
Dependent Claim 261 words
In a photographic camera, a combination comprising a housing having a chamber; a film-containing magazine removably accommodated in said chamber; a first guide portion having two walls defining therebetween an elongated groove; a second guide portion including an elongated rib, one of said guide portions being provided on said housing adjacent to said magazine, said rib extending with clearance into said groove to locate said magazine in said chamber with limited clearance; a first projection provided on one of said guide portions and abutting against the other guide portion in said groove to reduce said clearance; and a second projection provided on one of said guide portions and abutting against the other guide portion in said groove to further reduce said clearance; said projections being located at the opposite sides of said rib. 10 In a photographic camera, a combination comprising a housing having a chamber; a film-containing magazine removably accommodated in said chamber; a first guide portion having two walls defining therebetween an elongated groove; a second guide portion including an elongated rib, one of said guide portions being provided on said housing adjacent to said chamber and the other guide portion being provided on said magazine, said rib extending with clearance into said groove to locate said magazine in said chamber with limited clearance; and a projection provided on one of said guide portions and abutting against the other guide portion in said groove to reduce said clearance, the height of said projection approximating half the difference between the width of said groove and tHe width of said rib.
