Abstract

Abstract Apparatus for multiprinting photographs, particularly those taken with an instantaneous development still camera, are disclosed. The apparatus adapts such a camera resting on a planar surface for reproducing photographs or other documents, and includes an optical system, a first support member for mounting the optical system on the camera lens, a second support member for mounting the photograph, and a base connecting the two support members a predetermined distance apart so that when the optical system is mounted on the camera lens and the apparatus and the camera are both resting side by side on a planar surface, the optical axis of the camera and the apparatus are in optical alignment and ready for use for such photographic reproduction.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 176 words
Apparatus for adapting a camera which includes a photoelectric cell and which is resting on a planar surface for the reproduction of photographs or other documents comprising an optical system, a first support member for mounting said optical system on the lens of said camera, a second support member for mounting said photograph or other document to be reproduced, a base connecting said first support member to said second support member a predetermined distance from each other, said first support member, said base, and said second support member having a substantially U-shaped configuration when in use so that when said optical system is mounted on the lens of said camera, said apparatus and said camera are both resting side by side on said planar surface, the optical axis of said camera and said apparatus being in optical alignment and ready for use for said reproduction, and a diaphragm member mounted on said first support member for cooperation with said photoelectric cell whereby said diaphragm member can adjust the amount of light received by said photoelectric cell.
Claim 2
Dependent Claim 176 words
Apparatus for adapting a camera which includes a photoelectric cell and which is resting on a planar surface for the reproduction of photographs or other documents comprising an optical system, a first support member for mounting said optical system on the lens of said camera, a second support member for mounting said photograph or other document to be reproduced, a base connecting said first support member to said second support member a predetermined distance from each other, said first support member, said base, and said second support member having a substantially U-shaped configuration when in use so that when said optical system is mounted on the lens of said camera, said apparatus and said camera are both resting side by side on said planar surface, the optical axis of said camera and said apparatus being in optical alignment and ready for use for said reproduction, and a diaphragm member mounted on said first support member for cooperation with said photoelectric cell whereby said diaphragm member can adjust the amount of light received by said photoelectric cell.
Claim 3
Dependent Claim 70 words
The apparatus of claim 1 wherein said diaphragm member comprises a diaphragm plate slidably mounted on said first support member, said diaphragm plate including an aperture and being slidable between a first position wherein said photoelectric cell remains unobstructed by said diaphragm plate and a second position wherein said aperture is in alignment with said photoelectric cell so as to reduce the amount of light received by said photoelectric cell.
