Abstract
Abstract A camera wherein the shutter is opened in response to closing of a first electric switch on deformation of a diaphragm which also effects movement of a holder for the switch with reference to the camera housing to thereby actuate a second switch or a mechanical device which triggers the operation of the exposure control or of an indicator for scene brightness. The holder is movable against the opposition of a spring or a rubber ring which yields to permit closing of the second switch or the operation of the mechanical device before the diaphragm closes the first switch.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
88 words
In a photographic camera, a combination comprising holder means movable between first and second positions; first cameraactuating means operable in response to movement of said holder means to second position; biasing means arranged to urge said holder means to first position; second camera-actuating means provided on said holder means; and diaphragm means mounted on said holder means and being deformable to thereby operate said second actuating means in response to the application of a stress in a direction to effect movement of said holder means to second position.
Claim 2
Dependent Claim
88 words
In a photographic camera, a combination comprising holder means movable between first and second positions; first cameraactuating means operable in response to movement of said holder means to second position; biasing means arranged to urge said holder means to first position; second camera-actuating means provided on said holder means; and diaphragm means mounted on said holder means and being deformable to thereby operate said second actuating means in response to the application of a stress in a direction to effect movement of said holder means to second position.
Claim 3
Dependent Claim
14 words
A combination as defined in claim 1, wherein said biasing means comprises spring means.
Claim 4
Dependent Claim
14 words
A combination as defined in claim 1, wherein said biasing means consists of rubber.
Claim 5
Dependent Claim
19 words
A combination as defined in claim 1, wherein at least one of said actuating means comprises an electric switch.
Claim 6
Dependent Claim
19 words
A combination as defined in claim 1, wherein each of said actuating means comprises a normally open electric switch.
Claim 7
Dependent Claim
33 words
A combination as defined in claim 1, wherein one of said actuating means comprises a member movable from an idle position to an operative position in response to the application of said stress.
Claim 8
Dependent Claim
34 words
A combination as defined in claim 6, wherein said member is a lever which is pivotable between said idle and operative positions thereof, and further comprising means for biasing said lever to idle position.
Claim 9
Dependent Claim
55 words
A combination as defined in claim 1, wherein the force necessary to effect operation of said second actuating means exceeds the force which is required to move said holder means to second position so that said first actuating means is operated ahead of said second actuating means in response to the application of said stress.
Claim 10
Dependent Claim
31 words
A combination as defined in claim 1, further comprising a support and second holder means mounted in said support, said first-mentioned holder means being movably mounted in said second holder means.
