Abstract

Abstract Motion picture and still cameras for use with (1) a film cartridge of the type having a rectangular parallelepiped shaped casing with a minor depth dimension substantially smaller than the major length and width dimensions, an exposure opening in one of the smallest walls of the casing, and coaxial take-up and supply film rolls having their common axes parallel to the plane of the exposure opening and with (2) a film cartridge of the type having generally cylindrical supply and take-up chambers and means defining a film plane across which filmstrip may be advanced from the supply chamber to the take-up chamber, respectively. Each camera includes a housing having a plurality of walls forming a light-tight enclosure which defines a volume of generally rectangular parallelepiped shape with a minor depth dimension substantially smaller than the major length and width dimensions, the enclosure being adapted to removably receive such respective film cartridges. The cameras further include an optical system including a lens system and light reflector means for folding the light path from the scene along at least three optical axes to the film plane of a received cartridge. A zooming system may be imposed in at least one of the optical axes of the light path.

Claim 6
Dependent Claim 51 words
A camera as defined in claim 1 wherein: said three axes are substantially orthogonal; the second of said three axes taken in The direction of light travel towards said aperture is parallel to said plane of said aperture; and said first axis is parallel to the axes of the film rolls.
Claim 7
Dependent Claim 51 words
A camera as defined in claim 1 wherein: said three axes are substantially orthogonal; the second of said three axes taken in the direction of light travel towards said aperture is parallel to said plane of said aperture; and said first axis is perpendicular to the axes of the film rolls.
Claim 8
Dependent Claim 204 words
A motion picture camera adapted to receive a film cartridge of the type having a casing, coaxial film supply and take-up rolls, and an exposure opening defined by the casing and lying in a plane parallel to the common axis of the film rolls, said camera comprising: a housing; film gate means in said housing for supporting film from a received cartridge and defining an exposure aperture in a plane parallel to the plane of and adjacent the opening of a received cartridge, whereby film in such a cartridge may be exposed by light passing through said aperture and the exposure opening; means for transporting film supported by said film gate means past said aperture; means defined by said housing for admitting light from a scene to be photographed to the interior of said housing along a first optical axis generally parallel to the plane of said aperture; means oriented in said housing to reflect light passing through said light admitting means along a path including at least three successive axes and through said aperture; and zooming and compensating lens components in the next to last of said successive axes of said light path taken in the direction of light travel towards said aperture.
Claim 9
Dependent Claim 204 words
