Abstract
Abstract Photographic printing apparatus for making varying size prints with adjustable border settings, the various print sizes corresponding to different magnifications. The apparatus utilizes a two stage print paper advance mechanism continually referenced to horizontal and vertical optical center lines, whereby the sequential exposures of varying size including their respective borders are contiguous. The two stage advance also permits simplified marking of the print paper for subsequent cutting operations.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
199 words
In an adjustable masking mechanism for an image forming apparatus, the combination comprising: an image plane having at least one reference centerline; at least one pair of masks oppositely disposed about said centerline, each mask of said at least one pair of masks being equidistant therefrom; first control means operatIve to establish the overall image dimension relative to said centerline; second control means operative to establish a border along at least one of said masks of said at least one pair of masks, said second control means comprising a plurality of adjustment mechanisms corresponding to each of said masks, each of said adjustment mechanisms being independently operable to establish an independently variable border along its respective mask, cooperating with said first control means to establish the spacing between said pair of masks; material adapted to have an image formed thereon; and feed means operative in response to said first control means to provide a dimension of material established thereby in position proximate said pair of masks, as determined by said second control means cooperating with said first control means, whereby upon formation of an image on said material, a border as determined by said second control means is established.
Claim 2
Dependent Claim
199 words
In an adjustable masking mechanism for an image forming apparatus, the combination comprising: an image plane having at least one reference centerline; at least one pair of masks oppositely disposed about said centerline, each mask of said at least one pair of masks being equidistant therefrom; first control means operatIve to establish the overall image dimension relative to said centerline; second control means operative to establish a border along at least one of said masks of said at least one pair of masks, said second control means comprising a plurality of adjustment mechanisms corresponding to each of said masks, each of said adjustment mechanisms being independently operable to establish an independently variable border along its respective mask, cooperating with said first control means to establish the spacing between said pair of masks; material adapted to have an image formed thereon; and feed means operative in response to said first control means to provide a dimension of material established thereby in position proximate said pair of masks, as determined by said second control means cooperating with said first control means, whereby upon formation of an image on said material, a border as determined by said second control means is established.
Claim 3
Dependent Claim
173 words
The invention according to claim 1, wherein said at least one reference centerline comprises a first reference centerline, and said at least one pair of masks comprises a first pair of masks oppositely disposed about said first centerline, each mask being equidistant there-from, additionally comprising: a second reference centerline in said image plane, said second reference centerline being perpendicular to said first reference centerline; a second pair of masks oppositely disposed about said second centerline, each mask being equidistant therefrom; third control means operative to establish the overall image dimension relative to said second centerline; and fourth control means operative to establish a border along at least one mask of said second pair of masks, said fourth control means cooperating with said third control means to establish the spacing between said second pair of masks, said feed means being additionally responsive to said third and fourth control means to supply material of dimensions established thereby in position in the area defined by the opening established by said first and second pairs of masks.
Claim 4
Dependent Claim
37 words
The invention according to claim 2 wherein said fourth control means additionally operates to establish a border along the other mask of said second pair of masks, the two borders along the masks being of equal size.
Claim 5
Dependent Claim
49 words
The invention according to claim 2 wherein said fourth control means comprises third and fourth adjustment mechanisms corresponding respectively to the first and second masks of said second pair of masks, each of said adjustment mechanisms being independently operable to establish an independently variable border along its respective mask.
Claim 6
Dependent Claim
203 words
In photographic printing apparatus including a print plane adapted to receive paper for printing, a transparency holder and a light source adapted to be directed through a film transparency in the holder for projection onto the print plane, lens apparatus interposed between said transparency holder and said print plane operative to focus the image of said transparency on said print plane, horizontal and vertical pairs of masks disposed in said print plane over the print paper thereby defining the area of the print paper to be exposed and print paper feed mechanism to move the print paper in the print plane, improved border control apparatus comprising: first control means operative to set the vertical drive of the print paper feed mechanism to thereby define the length of the print area to be exposed; second control means operative to set the horizontal drive of the print paper feed mechanism to thereby define the width of the print area to be exposed; first adjustment means operative to set the pair of horizontal masks to establish top and bottom print borders for said print area; and second adjustment means operative to set the pair of vertical masks to establish side print borders for said print area.
Claim 7
Dependent Claim
203 words
In photographic printing apparatus including a print plane adapted to receive paper for printing, a transparency holder and a light source adapted to be directed through a film transparency in the holder for projection onto the print plane, lens apparatus interposed between said transparency holder and said print plane operative to focus the image of said transparency on said print plane, horizontal and vertical pairs of masks disposed in said print plane over the print paper thereby defining the area of the print paper to be exposed and print paper feed mechanism to move the print paper in the print plane, improved border control apparatus comprising: first control means operative to set the vertical drive of the print paper feed mechanism to thereby define the length of the print area to be exposed; second control means operative to set the horizontal drive of the print paper feed mechanism to thereby define the width of the print area to be exposed; first adjustment means operative to set the pair of horizontal masks to establish top and bottom print borders for said print area; and second adjustment means operative to set the pair of vertical masks to establish side print borders for said print area.
Claim 8
Dependent Claim
27 words
The invention according to claim 5 wherein said first adjustment means includes third and fourth controls operative to set independently variable top and bottom print borders, respectively.
Claim 9
Dependent Claim
27 words
The invention according to claim 5 wherein said second adjustment means includes third and fourth controls operative to set independently variable left and right print borders, respectively.
Claim 10
Dependent Claim
21 words
The invention according to claim 5 wherein said first adjustment means is operative to set equal top and bottom print borders.
Claim 11
Dependent Claim
21 words
The invention according to claim 5 wherein said second adjustment means is operative to set equal left and right print borders.
