Abstract
Abstract A camera capable of taking a plurality of different exposures on a single frame of film using only one lens-shutter combination. A beam shifting assembly rotates to a plurality of different positions to distribute the images sequentially, thus enabling the camera to provide a plurality of different exposures on a single frame of film. Double-exposure prevention is provided both between the different images on each frame and between the different frames. The camera is provided with a "Polaroid" type back so as to enable almost simultaneous developing of the frames, once taken. The camera also includes an aiming light to facilitate proper subject positioning. In addition a strobe socket is provided for strobe energization when using low-speed film.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
328 words
In a camera capable of separately exposing a plurality of portions of a single film frame laying in a film plane, a lens, a shutter and shutter actuation means, beam shifting means comprising a pair of mirrors associated with said lens and defining an image beam entrance plane through which an image beam enters said beam shifting means from said lens, and an image beam exit plane through which said image beam exits from said beam shifting means, said beam shifting means shifting said exit image beam with respect to said entering image beam, light barrier means mounted on said beam shifting means and adjacent said entrance and exit planes of said beam shifting means preventing any image beam from reaching said film plane which is not reflected by both said pair of mirrors, said beam shifting means being mounted on rotatable means for rotatable movement about an axis through said lens to a plurality of different positions, an electrical motor operatively engaging said rotatable means for rotation thereof, a plurality of detents in said rotatable means, equal in number to said plurality of positions of said beam shifting means and corresponding thereto, means segregating said film frame into a plurality of light-tight portions, each of said portions corresponding to one of said plurality of different positions of said beam shifting means, a circuit for energizing said electrical motor including sensing means, said sensing means operative to deenergize said motor when said sensing means senses one of said plurality of detents, and means for precluding the operation of said shutter accuation means when said sensing means does not sense one of said plurality of detents, an additional detent in said rotatable means, second sensing means positioned so as to sense said additional detent subsequent to a plurality of exposures, equal in number to said plurality of detents, and memory means, normally in one condition, and operative to a second condition to indicate the sensing of said additional detent.
Claim 2
Dependent Claim
328 words
In a camera capable of separately exposing a plurality of portions of a single film frame laying in a film plane, a lens, a shutter and shutter actuation means, beam shifting means comprising a pair of mirrors associated with said lens and defining an image beam entrance plane through which an image beam enters said beam shifting means from said lens, and an image beam exit plane through which said image beam exits from said beam shifting means, said beam shifting means shifting said exit image beam with respect to said entering image beam, light barrier means mounted on said beam shifting means and adjacent said entrance and exit planes of said beam shifting means preventing any image beam from reaching said film plane which is not reflected by both said pair of mirrors, said beam shifting means being mounted on rotatable means for rotatable movement about an axis through said lens to a plurality of different positions, an electrical motor operatively engaging said rotatable means for rotation thereof, a plurality of detents in said rotatable means, equal in number to said plurality of positions of said beam shifting means and corresponding thereto, means segregating said film frame into a plurality of light-tight portions, each of said portions corresponding to one of said plurality of different positions of said beam shifting means, a circuit for energizing said electrical motor including sensing means, said sensing means operative to deenergize said motor when said sensing means senses one of said plurality of detents, and means for precluding the operation of said shutter accuation means when said sensing means does not sense one of said plurality of detents, an additional detent in said rotatable means, second sensing means positioned so as to sense said additional detent subsequent to a plurality of exposures, equal in number to said plurality of detents, and memory means, normally in one condition, and operative to a second condition to indicate the sensing of said additional detent.
Claim 3
Dependent Claim
36 words
The camera of claim 1 which further includes means operatively associating said memory means and said shutter accuation means to preclude operation of said shutter accuation means when said memory means is in its second condition.
Claim 4
Dependent Claim
70 words
The camera of claim 2 which further indicates means to preclude energization of said electrical motor when said memory means is in its second condition, film supply means and third sensing means cooperating with said film supply means to sense positioning of an unexposed film frame in said film plane, and means operative to return said memory means to said first condition on an operation of said third sensing means.
Claim 5
Dependent Claim
82 words
The camera of claim 3 which further includes fourth sensing means operatively associated with said shutter to sense when said shutter is fully opened, supplementary light source energization means for supplying electrical energy for energization of said source, selecting means to indicate whether a supplemental light source is necessary, and means for energizing said supplemental light source means when said fourth sensing means senses said shutter in its fully opened position and said selecting means indicates a supplementary light source is necessary.
