Abstract
Abstract A compact miniature camera having a binocular type viewing system incorporated to sight along the hollow shafts of 35 mm. film spools includes an adjustable viewing system to accommodate different eye spacings. The film spools are mounted on each side of the camera housing to move 35 mm. film across a flat bottom wall of the camera housing, and an object lens mounted between the film spools transmits light to a reflecting mirror for directing light radiating from the object area to be photographed onto the film positioned on the bottom wall portion. Photo cell means for sensing light intensity along with controls for setting the focus, aperture opening and shutter speed of the camera are provided.

Claim 1
Independent Claim
338 words
A compact miniature camera, comprising: an enclosed housing structure defining a front wall portion, a rear wall portion and a substantially flat bottom wall portion: an object lens means mounted for receiving light radiating from an object area to be photographed through said front wall and the axis of said object lens being substantially parallel with the plane of said bottom wall portion; light directing means mounted within said housing structure behind said object lens means, said light directing means being positioned along the optical axis of said object lens means for directing object area light transmitted by said object lens means at a 90* angle downwardly onto said bottom wall portion; a pair of film spools each having a hollow shaft rotatably mounted within said housing structure extending from said front wall portion to said rear wall portion, said film spools being positioned one on either side of said object lens means with the axes of said spools substantially parallel to the optical axis of said object lens means; means defining a film path from one of said spools to the other across the inside surface of said bottom wall portion positioning the film for exposure to light from said light directing means; selectively operable means for winding film from one of said spools to the other whereby to move film across the inside surface of said bottom wall portion; and optical viewing means mounted to sight along the hollow shaft of each of said spools including a front movable lens and a rear rotatable double reflecting eyepiece whereby to form a binocular type viewing system for viewing the object area to be photographed with the optical axis of said viewing means being in the same plane as optical axis of said object lens, said front movable lens being movable longitudinally with respect to the axis of said spools for focusing said optical viewing means, said double reflecting eyepieces being rotatable about the axes of said spools to adjust said optical viewing means for different eye spacing.

A compact miniature camera, comprising: an enclosed housing structure defining a front wall portion, a rear wall portion and a substantially flat bottom wall portion: an object lens means mounted for receiving light radiating from an object area to be photographed through said front wall and the axis of said object lens being substantially parallel with the plane of said bottom wall portion; light directing means mounted within said housing structure behind said object lens means, said light directing means being positioned along the optical axis of said object lens means for directing object area light transmitted by said object lens means at a 90* angle downwardly onto said bottom wall portion; a pair of film spools each having a hollow shaft rotatably mounted within said housing structure extending from said front wall portion to said rear wall portion, said film spools being positioned one on either side of said object lens means with the axes of said spools substantially parallel to the optical axis of said object lens means; means defining a film path from one of said spools to the other across the inside surface of said bottom wall portion positioning the film for exposure to light from said light directing means; selectively operable means for winding film from one of said spools to the other whereby to move film across the inside surface of said bottom wall portion; and optical viewing means mounted to sight along the hollow shaft of each of said spools including a front movable lens and a rear rotatable double reflecting eyepiece whereby to form a binocular type viewing system for viewing the object area to be photographed with the optical axis of said viewing means being in the same plane as optical axis of said object lens, said front movable lens being movable longitudinally with respect to the axis of said spools for focusing said optical viewing means, said double reflecting eyepieces being rotatable about the axes of said spools to adjust said optical viewing means for different eye spacing.
Claim 3
Dependent Claim
125 words
The invention recited in claim 1, wherein: said housing structure defines a top wall portion substantially parallel with said bottom wall portion and rounded side wall portions for connecting said top wall portion to said bottom wall portion, said rounded side wall portions being dimensioned to enclose said film spools, said rounded side wall portions being maintained a predetermined distance apart and in a predetermined alignment; said front wall portion is substantially parallel with said back wall portion and perpendicular to said top and bottom wall portions; and said film spools are mounted symmetrically on either side of said object lens means with the axes of said film spools being substantially parallel to said bottom wall portion and substantially perpendicular to said front wall portion.
