Abstract
Abstract A camera having a flash mounted thereon is provided wherein the flash is moveable with respect to the optical axis of the camera to avoid red eye. When flash must be used, the flash may be raised and one or more pins are provided to automatically disengage the aperture control mechanism from an automatic exposure meter system and engage it with the focusing ring of the camera to automatically adjust aperture as a function of lens to object distance.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
132 words
In a camera having a housing, an objective lens, an adjustable diaphragm, focusing means, and an automatic exposure controlling device, the combination of means selectively controlling said adjustable diaphragm by said focusing means or by said automatic exposure controlling device, an electronic flash, means movably mounting said electronic flash on said housing from a first position relative to the optical axis of said objective lens to a second position located at a sufficiently greater distance relative to the optical axis of said objective lens to prevent the red-eye phenomenon during the electronic flash operation, and means controlled by movement of said electronic flash mounting means to its second position for operating said selectively controlling means to transfer control of said adjustable diaphragm from said automatic exposure controlling device to said focusing means.
Claim 2
Dependent Claim
132 words
In a camera having a housing, an objective lens, an adjustable diaphragm, focusing means, and an automatic exposure controlling device, the combination of means selectively controlling said adjustable diaphragm by said focusing means or by said automatic exposure controlling device, an electronic flash, means movably mounting said electronic flash on said housing from a first position relative to the optical axis of said objective lens to a second position located at a sufficiently greater distance relative to the optical axis of said objective lens to prevent the red-eye phenomenon during the electronic flash operation, and means controlled by movement of said electronic flash mounting means to its second position for operating said selectively controlling means to transfer control of said adjustable diaphragm from said automatic exposure controlling device to said focusing means.
Claim 3
Dependent Claim
52 words
In a camera according to claim 1, the combination of an on-off switch for use in the power circuit of said electronic flash, and means responsive to movement of said electronic flash mounting means for opening said switch in the first position thereof and closing said switch in the second position thereof.
Claim 4
Dependent Claim
93 words
In a camera according to claim 1, in which said means selectively controlling said adjustable diaphragm includes a ring rotatably mounted in said housing coaxially with said objective lens, and lever means pivotally mounted in said housing connected at one end to said rotatably mounted ring and at its other end in the path of movement of said electronic flash mounting means, and a pair of spaced members on said movable electronic flash mounting means positioned to engage the cooperating end of said lever means at the extreme positions of said electronic flash.
