Abstract
Abstract A miniature still camera wherein a cover of the housing is reciprocable with respect to the lens-containing section of the housing and the cover contains a socket for indexible or non-indexible sources of artificial illumination. The camera is ready to make an exposure when the cover is moved to an extended position to increase the length of the housing; the source of artificial light is then sufficiently remote from the lens to insure satisfactory exposures of color film to artificial light even though the source of artificial light is not connected to the socket by an extender. An indexible socket can be rotated in response to movement of the cover with respect to the lens-containing section, and the cover can contain a mechanism which fires percussively ignitable flash lamps in response to actuation of the camera release. When the length of the housing is reduced, the socket is received in the space between the objective and the eyepiece of the viewfinder in the lens-containing section of the housing.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
152 words
A camera comprising: a first housing section; a viewfinder in said first section having a pair of spaced-apart lens elements; a second housing section slidable on said first section between a closed position and an extended position and forming with said first section in said closed position a closed housing; a picture-taking lens on said first housing section; a socket on said second housing section positioned between said elements in said closed position and remote from said elements in said extended position, said socket being adapted to receive a flash source; a first pair of conductors fixed in said first housing section; and a second pair of conductors fixed in said second housing section and enclosed with said first pair in said housing in said closed position of said second section, the conductors of one of said pairs riding on and continuously making electrical contact with the conductors of the other pair.
Claim 2
Dependent Claim
152 words

Claim 3
Dependent Claim
20 words
The camera defined in claim 1, further comprising means for yieldably biasing said second section into one of said positions.
Claim 4
Dependent Claim
20 words
The camera defined in claim 2 wherein said means for biasing continuously urges said second section into said extended position.
Claim 5
Dependent Claim
40 words
The camera defined in claim 1 wherein said second section comprises a portion which is located in front of said lens in said closed position, whereby said camera can only make exposures in said extended position of said second section.
Claim 6
Dependent Claim
43 words
The camera defined in claim 1 wherein said second section comprises a portion which is located in front of said viewfinder in said closed position, whereby a subject can only be seen through said viewfinder in said extended position of said second section.
Claim 7
Dependent Claim
25 words
The camera defined in claim 1 wherein each of said conductors of one of said pairs telescopes with a respective conductor of the other pair.
Claim 8
Dependent Claim
36 words
The camera defined in claim 1 wherein said one pair of conductors comprises a pair of discrete contacts and said other pair of conductors comprises two elongated plate-like conductors each engaged by one of said contacts.
Claim 9
Dependent Claim
14 words
The camera defined in claim 7 wherein said one pair is said first pair.
Claim 10
Dependent Claim
19 words
The camera defined in claim 7 wherein said contacts have elastic portions which bear against the respective plate-like conductors.
Claim 11
Dependent Claim
21 words
The camera defined in claim 1, further comprising a source of electrical energy connected to at least one of said conductors.
Claim 12
Dependent Claim
21 words
The camera defined in claim 10 wherein said second section is formed with a compartment receiving said source of electrical energy.
Claim 13
Dependent Claim
15 words
The camera defined in claim 10 wherein said source of electrical energy is a battery.
Claim 14
Dependent Claim
12 words
The camera defined in claim 1 wherein said source is a flashbulb.
Claim 15
Dependent Claim
12 words
The camera defined in claim 1 wherein said source is a flashbar.
