Abstract
Abstract A camera for selectively filming at least two separate types of input images through at least one first and second object lens. Each first object lens is mounted on a part rotatable support which is in turn mounted on a rotatable lens carrier. Also mounted on the support are optical deflectors arranged to direct the image of a second object on to the film. In an alternative embodiment the second object lenses and deflectors are mounted on separate slides.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
90 words
Optical input means for a microfiche camera adapted to allow selective filming of inputs from at least two different optical sources which comprises: a rotatable turret plate having mounted thereon a plurality of pivoted support plates, each support plate carrying a lens and a mirror and adapted to pivot in the plane of the turret plate between two positions, the first of said positions placing the lens in the optical axis of the camera and the second of said positions placing the mirror in the optical axis of the camera.
Claim 2
Dependent Claim
90 words
Optical input means for a microfiche camera adapted to allow selective filming of inputs from at least two different optical sources which comprises: a rotatable turret plate having mounted thereon a plurality of pivoted support plates, each support plate carrying a lens and a mirror and adapted to pivot in the plane of the turret plate between two positions, the first of said positions placing the lens in the optical axis of the camera and the second of said positions placing the mirror in the optical axis of the camera.
Claim 3
Dependent Claim
30 words
The means of claim 1 further including a masking means adapted to be disposed in the optical axis of said camera and in the back focal plane of said lens.
Claim 4
Dependent Claim
24 words
The means of claim 2 wherein the masking means is provided on a mask plate which can be shifted to provide different size masks.
Claim 5
Dependent Claim
52 words
The means of claim 3 wherein the mask plate is rotatable about the same axis as the rotatable, turret plate wherein the mask comprises a plurality of masking apertures and wherein at least one sub mask is provided on the mask plate so as to further mask at least one said aperture.
Claim 6
Dependent Claim
24 words
The means of claim 4 wherein said sub mask is mounted in guides for radial movement toward or away from the mask plate axis.
Claim 7
Dependent Claim
56 words
The means of claim 5 wherein the sub mask is urged toward the mask axis by a weak spring and wherein engagement means are provided adjacent the mask plate to engage the sub mask and draw said sub mask into position away from the axis of the mask plate against the action of the weak spring.
Claim 8
Dependent Claim
64 words
The means of claim 6, wherein the engagement means comprises a pawl means actuated with an engagement position with the sub mask by a solenoid against the action of a strong spring, whereby on switching off the actuation current provided to the solenoid the strong spring overcomes the action of the weak spring to draw the sub mask away from the mask plate axis.
Claim 9
Dependent Claim
111 words
A camera provided with a film carrier, a shutter having shutter blades, a plurality of first object lenses, a mask provided in the back focal plane of said lenses, an optical deflector associated with each object lens mounted on a first slide means for movement into and out of an optical path leading past said shutter blades to said film carrier, at least one mask provided on a second slide means mounted between the first slide and said shutter blades for movement across said optical path, a rotatable lens carrier mounted about an axis at right angles to said optical path, wherein the first object lenses are mounted to said carrier.
Claim 10
Dependent Claim
111 words
A camera provided with a film carrier, a shutter having shutter blades, a plurality of first object lenses, a mask provided in the back focal plane of said lenses, an optical deflector associated with each object lens mounted on a first slide means for movement into and out of an optical path leading past said shutter blades to said film carrier, at least one mask provided on a second slide means mounted between the first slide and said shutter blades for movement across said optical path, a rotatable lens carrier mounted about an axis at right angles to said optical path, wherein the first object lenses are mounted to said carrier.
Claim 11
Dependent Claim
14 words
A camera as claimed in claim 8 wherein said camera is a microfiche camera.
Claim 12
Dependent Claim
27 words
A camera as claimed in claim 8 wherein a cathode ray tube is mounted to project an image through at least one of said first object lenses.
