Claim 8

In a camera for successively and simultaneously effecting a pair of split image exposures on a single photosensitive surface, the improvement comprising two pairs of lens openings, each pair for effecting a split image exposure of a different region of the photosensitive material, an optical mask disposed between said lens openings and said film, said mask defining a first pair of apertures, a second pair of apertures and a third double pair of apertures, means for rotating said mask to sequentially align said first pair of apertures with one pair of said lens openings and second pair of apertures with the second pair of lens openings and for alternatively aligning said double pair of apertures with both pairs of said lens openings, a shutter plate defining an exposure slot for each lens opening, an axial extension formed on said shutter plate, means for reciprocably rotating said shutter plate between an open position to expose regions of the film through lens openings aligned with optical mask apertures and a closed position wherein the film is optically separated from said lens openings, said shutter operating means comprising a rotatable disc having a pin engageable with said axial extension for initiating movement of said shutter from said closed to said open position and a bias spring connected to said shutter plate for moving said shutter plate from said open to said closed position, switch means responsive to said shutter operating means for initiating operation of said mask rotating means to rotate said mask from a first position wherein the said first pair of mask apertures are aligned with a first pair of lens openings to a second position wherein said second pair of mask apertures are aligned with a second pair of lens openings, second switch means for altering operation of said mask rotating means to align all of said third double pair of apertures with all of said lens openings whereby split image exposures of different regions of the film may be effected sequentially through said first and second pairs of apertures and alternatively simultaneously through said third double pair of apertures.

Claim 9

An exposure assembly for simultaneously or sequentially exposing each of a plurality of regions within a fixed area through a plurality of lens openings comprising lens support structure for defining a group of lens openings for each region to be exposed, optical masking means disposed between said lens openings and said area, said optical masking means defining first and second pluralities of apertures, each plurality of apertures corresponding to the number of lens openings, means for positioning said optical masking means to sequentially align different groups of said apertures from said first plurality with successive groups of said lens openings, and for alternatively aligning all of said apertures from said second plurality with all of said lens openings, shutter means disposed between said lens apertures and said area to be exposed, and means for operating said shutter to simultaneously expose those regions within said area through those apertures in said optical masking means aligned therewith and with lens openings.

Claim 10

An exposure assembly for simultaneously or sequentially exposing each of a plurality of regions within a fixed area through a plurality of lens openings comprising lens support structure for defining a group of lens openings for each region to be exposed, optical masking means disposed between said lens openings and said area, said optical masking means defining first and second pluralities of apertures, each plurality of apertures corresponding to the number of lens openings, means for positioning said optical masking means to sequentially align different groups of said apertures from said first plurality with successive groups of said lens openings, and for alternatively aligning all of said apertures from said second plurality with all of said lens openings, shutter means disposed between said lens apertures and said area to be exposed, and means for operating said shutter to simultaneously expose those regions within said area through those apertures in said optical masking means aligned therewith and with lens openings.
