Abstract
Abstract A still camera wherein the main section or body of the housing guides a reciprocable cover member of the housing. The cover member is movable between an extended position and a concealing position and is permanently biased to the extended position by a helical spring. When moved by hand to the concealing position, the cover member overlies the view finder and the picture taking lens in the body and can also block the actuation of camera release. The cover member can be locked in such concealing position by a detent mechanism which includes a tooth on the cover member and a complementary tooth which is mounted in the body and can be moved by a knob into or from engagement with the tooth of the cover member. The latter can transport the film, cock the shutter, advance the exposure counter and/or perform other functions during movement from extended to concealing position or vice versa.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
354 words
In a photographic apparatus, a combination comprising an elongated housing including a first section and a second section supported by and reciprocable relative to said first section in the longitudinal direction of said housing between first and second positions in which one of said sections respectively conceals and exposes at least a portion of the other of said sections; a picture taking lens mounted in said other section and having an optical axis normal to said direction; resilient means reacting against said first section and arranged to bias said second section to said second position so that said second section invariably tends to assume said second position; film transporting means in said other section, said one section having means for actuating said film transporting means simultaneously with and as a result of a portion of movement of said second section from said second to said first and back to said second position thereof; and detent means for releasably holding said second section in said first position, including first and second locking portions respectively mounted on said first and second sections, one of said locking portions being movable to and from an operative position in which said one locking portion engages with the other of said locking portions to maintain said second section in said first position when the movement of said one locking portion to said operative position takes place while said second section occupies said first position and to automatically hold said second section against movement from said first position when the movement of said one locking portion to said operative position precedes the movement of said second section to said first position, said detent means further comprising displacing means mounted on said housing and being operable by hand to move said one locking portion not only to but also from said operative position in each and every position of said second section relative to said first section so that said one locking portion remains in the position selected therefor by said displacing means unless said displacing means is again operated by hand to move said one locking portion from said selected position.

In a photographic apparatus, a combination comprising an elongated housing including a first section and a second section supported by and reciprocable relative to said first section in the longitudinal direction of said housing between first and second positions in which one of said sections respectively conceals and exposes at least a portion of the other of said sections; a picture taking lens mounted in said other section and having an optical axis normal to said direction; resilient means reacting against said first section and arranged to bias said second section to said second position so that said second section invariably tends to assume said second position; film transporting means in said other section, said one section having means for actuating said film transporting means simultaneously with and as a result of a portion of movement of said second section from said second to said first and back to said second position thereof; and detent means for releasably holding said second section in said first position, including first and second locking portions respectively mounted on said first and second sections, one of said locking portions being movable to and from an operative position in which said one locking portion engages with the other of said locking portions to maintain said second section in said first position when the movement of said one locking portion to said operative position takes place while said second section occupies said first position and to automatically hold said second section against movement from said first position when the movement of said one locking portion to said operative position precedes the movement of said second section to said first position, said detent means further comprising displacing means mounted on said housing and being operable by hand to move said one locking portion not only to but also from said operative position in each and every position of said second section relative to said first section so that said one locking portion remains in the position selected therefor by said displacing means unless said displacing means is again operated by hand to move said one locking portion from said selected position.
Claim 3
Dependent Claim
37 words
A combinaton as defined in claim 1, wherein said picture taking lens is mounted in said portion of said other section so as to be at least partly concealed in said first position of said first section.
Claim 4
Dependent Claim
36 words
A combination as defined in claim 1, further comprising view finder means mounted in said portion of said other section so as to be at least partially concealed in said first position of said second section.
Claim 5
Dependent Claim
20 words
A combination as defined in claim 1, wherein said displacing means is mounted on said other section of said housing.
Claim 6
Dependent Claim
35 words
A combination as defined in claim 1, wherein said locking portions have teeth which engage each other in the operative position of said one locking portion and in the first position of said second section.
