Abstract

Abstract The present invention relates to the optional production either of a large-format photograph or of a number of small-format photographs with the same total surface area and the apparatus therefor. An object to be photographed is used to produce optionally either a large-format picture by way of a plain light deflection element and a lens of long focal length or a number of smaller picture in a single take by way of at least two light deflection elements arranged at an angle to one another and a lens of short focal length. The two lenses and the light deflection elements thereby are pivoted selectively in front of a photographic device.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 213 words
Apparatus for making either a single large-format photograph or a number of small-format photographs with a total surface area which is the same as that of the Large single photograph comprising: a. a magazine for dispensing a strip of unexposed negative material from a feeding station to an exposing station; b. a feeder mechanism which moves the negative material toward the exposing station from the dispensing magazine and away from the exposing station to the outlet; c. exposing means mounted at the exposing station between the dispensing magazine and the outlet; d. said exposing means comprising a turret holder having a pivotable object lens mounting plate with a holder for two object lenses, one of long focal length and one of short focal length, at least two light deflection elements arranged at an angle to each other, a drop flap masking means, shaft and pull cord mechanism to pivotably move either the long focal length object lens or the short focal length object lens into exposing position for the negative material; and, e. motor means for moving the pull cord and drop flap and for pivoting the lens mounting plate, whereby the movement of the short focal length lens in relation to said light deflection elements provides the number of small format photographs.
Claim 2
Dependent Claim 213 words
Apparatus for making either a single large-format photograph or a number of small-format photographs with a total surface area which is the same as that of the Large single photograph comprising: a. a magazine for dispensing a strip of unexposed negative material from a feeding station to an exposing station; b. a feeder mechanism which moves the negative material toward the exposing station from the dispensing magazine and away from the exposing station to the outlet; c. exposing means mounted at the exposing station between the dispensing magazine and the outlet; d. said exposing means comprising a turret holder having a pivotable object lens mounting plate with a holder for two object lenses, one of long focal length and one of short focal length, at least two light deflection elements arranged at an angle to each other, a drop flap masking means, shaft and pull cord mechanism to pivotably move either the long focal length object lens or the short focal length object lens into exposing position for the negative material; and, e. motor means for moving the pull cord and drop flap and for pivoting the lens mounting plate, whereby the movement of the short focal length lens in relation to said light deflection elements provides the number of small format photographs.
Claim 3
Dependent Claim 26 words
Apparatus as claimed in claim 1, wherein said drop flap masking means includes a mask for framing the aperture in the shape of a rectangular frame.
Claim 4
Dependent Claim 41 words
Apparatus as claimed in claim 1, wherein the object lens of long focal length is connected rigidly to a light deflection element which consists of a plane mirror mounted at an angle of 45* to the axis of said object lens.
Claim 5
Dependent Claim 37 words
Apparatus as claimed in claim 1, wherein said light deflection elements consist of two plane mirrors mounted with their common edges intersecting the axis of the object lens of short focal length to enclose an obtuse angle.
