Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
151 words
A camera comprising a housing, a lens mounted on one wall of the housing and having a fixed optical axis, focusing means operatively connected to said lens and adjustably mounted on said housing for varying the focal length of said lens, and a selfcontained light system mounted on a second wall of said housing for movement between an extended operative position and a retracted inoperative position; said light system including a reflector piece having a light source disposed therein whereby said light source and reflector piece are movable only as a unit between extended and retracted positions; mounting means interconnecting said reflector piece and said housing; and actuating means carried on said housing and being responsive to the adjustment of said focusing means to effect tilting of said reflector piece and light source relative to the lens optical axis, only when said light system is disposed in said extended operative position.
Claim 2
Dependent Claim
151 words
A camera comprising a housing, a lens mounted on one wall of the housing and having a fixed optical axis, focusing means operatively connected to said lens and adjustably mounted on said housing for varying the focal length of said lens, and a selfcontained light system mounted on a second wall of said housing for movement between an extended operative position and a retracted inoperative position; said light system including a reflector piece having a light source disposed therein whereby said light source and reflector piece are movable only as a unit between extended and retracted positions; mounting means interconnecting said reflector piece and said housing; and actuating means carried on said housing and being responsive to the adjustment of said focusing means to effect tilting of said reflector piece and light source relative to the lens optical axis, only when said light system is disposed in said extended operative position.
Claim 3
Dependent Claim
40 words
The camera of claim 1 including biasing means cooperating with said reflector piece to bias the latter to assume a first predetermined angular position relative to said mounting means when said light system is disposed in said extended operative position.
Claim 4
Dependent Claim
36 words
The camera of claim 1 wherein the actuating means comprises an elongated follower element having one end thereof engaging cam means formed on the focusing means, and the opposite end thereof operatively engaging the mounting means.
Claim 5
Dependent Claim
128 words
The camera of claim 3 including a manually adjustable light control member mounted on a wall of said camera housing, an iris member adjustably mounted within said housing for movement between an operative position in alignment with the lens optical axis and an inoperative position spaced from said optical axis, said light control member having cam means in engagement with a first laterally projecting portion of said elongated follower element, said element being provided with a second laterally projecting portion in operative engagement with said iris member whereby adjustment of said light control member in one direction effects movement of said iris member to said operative position, and adjustment of said light control member in a second direction effects movement of said iris member to said inoperative position.
Claim 6
Dependent Claim
93 words
The camera of claim 1 wherein said light system, when in said retracted inoperative position, having the reflector piece and light source and the mounting means therefor disposed within a recess formed in the second wall of said housing; said light system including means for biasing said reflector piece and light source and said mounting means to assume an extended operative position; said housing being provided with a manually adjustable latch means for retaining said reflector piece and light source and said mounting means in said retracted inoperative position within said housing recess.
Claim 7
Dependent Claim
34 words
The camera of claim 5 wherein the mounting means includes means for rendering the actuating means non-responsive to the adjustment of the focusing means when said light system is in the retracted inoperative positiOn.
