Cylindrical lens bonded microfiche

Claim 2

A composite microfiche formed of two laminar halves, each half defined by a generally flat substrate having parallel, spaced channels on one face thereof, each channel having a curved surface throughout its length to define a channel lens, the inter-channel surface on said one face being opaque, the two said halves placed with their channeled faces facing each other and with the channel lenses of one half crossing the channel lenses of the other half to define a projection lens at each crossing, one of said laminar halves carrying a photographic emulsion over a surface thereof.

Claim 3

The microfiche of claim 1 wherein said two halves are bonded together.

Claim 4

The microfiche of claim 1 wherein said channel lenses are convex.

Claim 5

The microfiche of claim 1 wherein said two halves are contiguous yet relatively movable in parallel planes, whereby the two halves may slide relative to each other and remain the same laminar thickness.

Claim 6

The microfiche of claim 1 including color filters positioned between said crossed lenses, the number of colors being at least two in number, one color being aligned with each channel lens of one of said laminar halves.

Claim 7

A microfiche reader/camera apparatus including a viewing screen parallel and spaced from a microfiche defined by a transparent substrate carrying a photographic emulsion on one surface, the other surface having a plurality of parallel, spaced channels each being curved on its surface throughout its length, the intra-channel surface of said other surface being opaque, a plurality of parallel, longitudinal lenses in the form of strips fixedly mounted with respect to said viewing screen, said strip lenses being contiguous to and crossing the said channel lenses, a projection lens defined at each such crossing, said microfiche substrate being slidable with respect to said strip lenses yet maintaining the same composite thickness.

Claim 8

A microfiche reader/camera apparatus including a viewing screen parallel and spaced from a microfiche defined by a transparent substrate carrying a photographic emulsion on one surface, the other surface having a plurality of parallel, spaced channels each being curved on its surface throughout its length, the intra-channel surface of said other surface being opaque, a plurality of parallel, longitudinal lenses in the form of strips fixedly mounted with respect to said viewing screen, said strip lenses being contiguous to and crossing the said channel lenses, a projection lens defined at each such crossing, said microfiche substrate being slidable with respect to said strip lenses yet maintaining the same composite thickness.

Claim 9

The microfiche apparatus of claim 6 including an apertured, opaque mask fixed relative to said viewing screen and to which said strip lenses are fixed, said strip lenses being aligned with and crossing said apertures.

Claim 10

The microfiche of claim 6 including color filters positioned between said crossed lenses, the number of colors being at least two in number, one color being aligned with each channel lens.

Claim 11

A laminar half for a composite microfiche, including, a transparent substrate having a plurality of parallel and convex, lens-forming corrugations on one surface thereof and carrying a photographic emulsion at the other surface thereof, the depressed areas of said corrugated surface between said lenses defining troughs and being opaque, said opaque areas extending laterally from the lowest parts of said troughs.

Claim 12

A laminar half for a composite microfiche, including, a transparent substrate having a plurality of parallel and convex, lens-forming corrugations on one surface thereof and carrying a photographic emulsion at the other surface thereof, the depressed areas of said corrugated surface between said lenses defining troughs and being opaque, said opaque areas extending laterally from the lowest parts of said troughs.

Claim 13

The laminar half of claim 9 including, a spacing boss positioned in a trough, whereby to abut a similar boss in a similar laminar half to thus space two such laminar halves.

Claim 14

The laminar half of claim 9 wherein said troughs are coated with an opaque film.

Claim 15

The laminar half of claim 9 wherein said troughs are filled with an opaque substance.

Claim 16

A microfiche having a photographic emulsion on one surface thereof, said emulsion carrying micro images, opaque bands carried by said emulsion and intersecting each other to function as optical stops, said bands intersecting each other thereby forming closed polygons, each of which encloses a distinct micro image.

Claim 17

A microfiche having a photographic emulsion on one surface thereof, said emulsion carrying micro images, opaque bands carried by said emulsion and intersecting each other to function as optical stops, said bands intersecting each other thereby forming closed polygons, each of which encloses a distinct micro image.
