Abstract
Abstract In a preferred embodiment, a camera convertible from a camera employing normal-focusing lens for picture-taking, to and from a camera employing telescopic lens, within a unitary housing, having the lens mechanism slidably movable intermittently as desired between the two alternate states, with the lenses shutter mechanism being a structure in fixed position behind the lens, in a predetermined position to alternately block exposing focused light and to transmit exposing focused light to an exposable film posterior to the lens shutter mechanism, the mechanism being a pivoted door structure spring-biased to a closed state of light-blocking function, actuatable intermittently to a light-exposing state by cocked force-exerting member acting through a slip-clutch mechanism.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
300 words
A camera shutter device comprising in combination: camera-works enclosure structure forming space therein substantially enclosed as an enclosed space; said camera-works enclosure structure being of a predetermined small size, and said enclosed space being a predetermined small space; camera lens means for alternately moving separate lenses of different focal lengths to and fro laterally to and from picture-taking position, including a first lens unit having a lens of normal focus and a second lens unit having a lens of telescopic lens focus, the camera lens means being mounted within a forward portion of said predetermined small space and adapted to receive light and to focus the light rearwardly substantially; door shutter means for channeling light from a camera lens to light-sensitive film, and for open and closing a door structure blocking light transmission when in a closed state, adapted to serve as a camera shutter for taking pictures by intermittent motion when actuated to a light-transmitting state, fixedly mounted on said camera-works enclosure structure within a rearward portion of said predetermined small space at a point rearward of the camera lens means and in juxtaposition to a rearward wall of the camera-works enclosure structure as a film light-receiving and exposing position, the door shutter means including a slip-clutch means for intermittently transmitting force to opening to a light-transmitting state; actuation means for intermittently driving said slip-clutch means to the light transmitting state; said door shutter means including a light barrier as the door structure, mounted to be moved to and from light-blocking positions by said actuation means, and the door shutter means further including a tubular light-channeling conduit-structure positioned in juxtaposition to the light-receiving and exposing position, and said light barrier being mounted within said tubular light-channeling conduit and adapted to be moved therewithin to and from the light-blocking positions.

A camera shutter device comprising in combination: camera-works enclosure structure forming space therein substantially enclosed as an enclosed space; said camera-works enclosure structure being of a predetermined small size, and said enclosed space being a predetermined small space; camera lens means for alternately moving separate lenses of different focal lengths to and fro laterally to and from picture-taking position, including a first lens unit having a lens of normal focus and a second lens unit having a lens of telescopic lens focus, the camera lens means being mounted within a forward portion of said predetermined small space and adapted to receive light and to focus the light rearwardly substantially; door shutter means for channeling light from a camera lens to light-sensitive film, and for open and closing a door structure blocking light transmission when in a closed state, adapted to serve as a camera shutter for taking pictures by intermittent motion when actuated to a light-transmitting state, fixedly mounted on said camera-works enclosure structure within a rearward portion of said predetermined small space at a point rearward of the camera lens means and in juxtaposition to a rearward wall of the camera-works enclosure structure as a film light-receiving and exposing position, the door shutter means including a slip-clutch means for intermittently transmitting force to opening to a light-transmitting state; actuation means for intermittently driving said slip-clutch means to the light transmitting state; said door shutter means including a light barrier as the door structure, mounted to be moved to and from light-blocking positions by said actuation means, and the door shutter means further including a tubular light-channeling conduit-structure positioned in juxtaposition to the light-receiving and exposing position, and said light barrier being mounted within said tubular light-channeling conduit and adapted to be moved therewithin to and from the light-blocking positions.
Claim 3
Dependent Claim
54 words
A camera shutter device of claim 1, in which said door shutter means includes a tubular light-channeling conduit-structure, and said slip-clutch means being mounted on the tubular light-channeling conduit adapted for intermittently permitting light to be transmitted through said through-passage space of the tubular light-channeling conduit structure to said film light-receiving and exposing position.
Claim 4
Dependent Claim
44 words
A camera shutter device of claim 2, including lens means for alternately positioning and providing telescopic lens and non-telescopic lens in light-focusing and transmitting state and position anterior to said door shutter means, at a forward end of through-space of the tubular light-channeling conduit-structure.
Claim 5
Dependent Claim
190 words
A camera shutter device of claim 1, in which the slip-clutch means comprises a lever structure mounted on the light barrier for moving the light barrier from and to the light-blocking positions when activated, and the lever structure including an inclined plane terminating in a step, and the slip-clutch means further including a movable force-exerting member mounted on and movable by the actuation means, the force-exerting member being positioned to be moved from a non-force-exerting position upwardly along said inclined plane and downwardly at said step at a position behind the lever structure, and a spring means for biasing the force-exerting member downwardly at said step position to the position behind the lever structure, and actuation means including locking means for intermittently locking the force-exerting member in said position behind the lever structure in a non-force-exerting member in said position behind the lever structure in a non-force-exerting state and for manual release to a force-exerting state against a rearward wall of the lever structure, and the actuation means further including setting means for advancing the force-exerting member along said inclined plane and downwardly to the position behind the lever structure.
Claim 6
Dependent Claim
44 words
A camera shutter device of claim 4, including lens means for alternately positioning and providing telescopic lens and non-telescopic lens in light-focusing and transmitting state and position anterior to said door shutter means, at a forward end of through-space of the tubular light-channeling conduit-structure.
Claim 7
Dependent Claim
44 words
A camera shutter device of claim 1, including lens means for alternately positioning and providing telescopic lens and non-telescopic lens in light-focusing and transmitting state and position anterior to said door shutter means, at a forward end of through-space of the tubular light-channeling conduit-structure.
Claim 8
Dependent Claim
33 words
A camera shutter device of claim 1, including lens means for alternately positioning and providing telescopic lens and non-telescopic lens in light-focusing and transmitting state and position anterior to said door shutter means.
Claim 9
Dependent Claim
119 words
A camera shutter device comprising in combination: a camera means including lens means for alternately positioning between to to fro transversly lateral positions relative to a predetermined focusing point receivable of light-receiving and exposable picture film; and a door shutter means for alternately blocking focused light to the predetermined focusing point, positioned posterior to and separated from the lens means, said camera means being for the alternate taking of telescopic and non-telescopic pictures, and said door shutter means including a light barrier and a tubular light-channeling conduit-structure positioned in juxtaposition to the light-receiving and exposing position, and the light barrier being mounted within said tubular light-channeling conduit and adapted to be moved therewithin to and from the light-blocking positions.
