Abstract
Abstract A compact and transportable apparatus for making instant prints from slides or transparencies, without the need for darkroom facilities, comprising: a housing, having a lens-shutter assembly and means for attaching a film pack in operable relation to the lens-shutter assembly; a slide station, having means for holding a slide or transparency to be copied; and, a light diffuser assembly, for evenly illuminating the slide during copying, whereby an optical path is formed in said diffuser assembly, passing through the slide or transparency, the lens-shutter assembly, and onto said film pack. The overall size of the apparatus may be reduced by interposing at least one mirror in the optical path.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
214 words
An apparatus for making prints from slides or transparencies, comprising: a housing having first, second and third compartments, each of said compartments being adjacent the other, and at least the first compartment being light tight; a lens-shutter assembly disposed between the first and second compartments, defining an inner wall; a slide station, having means for holding a slide or transparency to be copied, disposed between the second and third compartments, defining another inner wall; the first compartment having means for attaching a film pack to an outer wall, in operable relation to the lens-shutter assembly, said compartment being light tight when said film pack is attached, and further having at least one mirror optically interposed between the lens-shutter assembly and the film pack; the third compartment having first and second portions partially separated by a baffle wall and optically connected by light reflecting and diffusing panels, and having means for removeably mounting an artificial light source at the end of the compartment optically opposite from the slide station, whereby an optical path may be established, originating in the third compartment, at the defined opposite end, being reflected by the light diffusing panels through the slide station, passing through the lens-shutter assembly and being reflected by the at least one mirror onto the film pack.
Claim 2
Independent Claim
214 words
An apparatus for making prints from slides or transparencies, comprising: a housing having first, second and third compartments, each of said compartments being adjacent the other, and at least the first compartment being light tight; a lens-shutter assembly disposed between the first and second compartments, defining an inner wall; a slide station, having means for holding a slide or transparency to be copied, disposed between the second and third compartments, defining another inner wall; the first compartment having means for attaching a film pack to an outer wall, in operable relation to the lens-shutter assembly, said compartment being light tight when said film pack is attached, and further having at least one mirror optically interposed between the lens-shutter assembly and the film pack; the third compartment having first and second portions partially separated by a baffle wall and optically connected by light reflecting and diffusing panels, and having means for removeably mounting an artificial light source at the end of the compartment optically opposite from the slide station, whereby an optical path may be established, originating in the third compartment, at the defined opposite end, being reflected by the light diffusing panels through the slide station, passing through the lens-shutter assembly and being reflected by the at least one mirror onto the film pack.
Claim 3
Dependent Claim
16 words
The apparatus of claim 1, further comprising an artificial source of illumination in the third compartment.
Claim 4
Dependent Claim
12 words
The apparatus of claim 1, wherein said film pack comprises self-developing film.
Claim 5
Dependent Claim
11 words
The apparatus of claim 3, wherein said film pack is motorized.
Claim 6
Dependent Claim
18 words
The apparatus of claim 1, wherein the lens-shutter assembly includes means for synchronizing the artificial source of illumination.
Claim 7
Dependent Claim
21 words
The apparatus of claim 1, wherein said slide station further comprises means for keeping the slide or transparency flat during copying.
Claim 8
Dependent Claim
19 words
The apparatus of claim 1, wherein said lens-shutter assembly further comprises means for automatically controlling exposure of said film.
Claim 9
Dependent Claim
