Abstract
Abstract A foldable camera for self-developing film comprises a base housing and a movable member pivotable between a closed position integrated with the housing and an open, elevated position above the housing. The movable member is mounted to a supporting member which is pivotally coupled to the housing at the end opposite from the film exit end of the housing. An objective lens and a reflex mirror are fixedly mounted to the movable member in fixed relationship to each other such that they are in the proper positions for film exposure when the movable member is pivotted to the elevated position.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
173 words
In a folding camera of the type having a base housing for holding a film cassette containing a plurality of film sheets, means for exposing a film sheet to light received from a subject by an objective lens and reflected from a reflex mirror to the film sheet at an exposure position in the base housing, and means for developing the film sheet and advancing it from an exit end of the base housing, the improvement wherein said means for exposing comprises a movable member supporting said objective lens and reflex mirror which is movable between a closed position forming a closure to the base housing and an open position in which said movable member is elevated above said base housing, said objective lens being rididly fixed to said movable member at a distal end thereof in an operative position for exposure, and a supporting member connected to the other end of said movable member and being pivotally coupled to said base housing at an end thereof opposite from the film exit end.
Claim 2
Dependent Claim
173 words
In a folding camera of the type having a base housing for holding a film cassette containing a plurality of film sheets, means for exposing a film sheet to light received from a subject by an objective lens and reflected from a reflex mirror to the film sheet at an exposure position in the base housing, and means for developing the film sheet and advancing it from an exit end of the base housing, the improvement wherein said means for exposing comprises a movable member supporting said objective lens and reflex mirror which is movable between a closed position forming a closure to the base housing and an open position in which said movable member is elevated above said base housing, said objective lens being rididly fixed to said movable member at a distal end thereof in an operative position for exposure, and a supporting member connected to the other end of said movable member and being pivotally coupled to said base housing at an end thereof opposite from the film exit end.
Claim 3
Dependent Claim
32 words
The folding camera as defined in claim 1, wherein said objective lens is moved to an inoperative position within said base housing when said movable member is moved to the closed position.
Claim 4
Dependent Claim
63 words
The folding camera as defined in claim 1, wherein said reflex mirror is mounted to said movable member so as to form an angle in the open position with an upper surface of said base housing, and said supporting means is pivotally coupled at a position of the upper surface of said base housing in proximity to one end of said reflex mirror.
Claim 5
Dependent Claim
34 words
The folding camera as defined in claim 1, further comprising a built-in flash unit which is movable to an operative position in accordance with the movement of said movable member to said open position.
Claim 6
Dependent Claim
35 words
The folding camera as defined in claim 4, wherein said flash unit includes a condenser, wherein a charging operation of said condenser is automatically started when said movable member is moved to the open position.
Claim 7
Dependent Claim
52 words
The folding camera as defined in claim 1, further comprising a light shielding member for shielding an opening formed between said base housing and said movable member in the open position, said light shielding member being spring biased to close said opening when said movable member is moved to the open position.
Claim 8
Dependent Claim
49 words
The folding camera as defined in claim 1, wherein said objective lens and said reflex mirror are rigidly mounted to said movable member in a fixed positional relationship to each other for exposing the film sheet at the exposure position when said movable member is in the open position.
Claim 9
Dependent Claim
236 words
In a folding camera of the type having a base housing for holding a film cassette containing a plurality of film sheets therein, means for exposing a film sheet with light from a subject received by an objective lens and reflected from a reflex mirror to the film sheet at an exposure position in the base mounting, and means for developing the film sheet and advancing it out from exit end of said housing, the improvement comprising a movable member mounting said objective lens and said reflex mirror which is movable between a closed position forming a closure to said base housing and an open position in which it is elevated above said base housing, and a supporting member connected to one end of said movable member and being pivotally coupled to the base housing, wherein said objective lens is rigidly mounted to a lock arm, one end of which is pivotally connected to a distal end of said movable member, and the other end of which is held in cam slot defined within said base housing and movable between an operative position for said objective lens and an inoperative position wherein said objective lens is folded in the base housing, and wherein said reflex mirror is rigidly mounted to said movable menber so as to be in an operative positional relationship with said objective lens when said movable member is moved to the open position.
