Abstract

Abstract A graphic arts camera constructed according to the present invention includes a copyboard, lens with bellows, a film holder and a light image reflector disposed in vertically extending parallel planes and spaced longitudinally apart. The film holder and the light image reflector are pivotally mounted on frames having rollers engaging a pair of overhead tracks for traveling thereon. The film holder is adapted to be adjustably positioned from its parallel wrong reading position with respect to the copyboard and lens to an angular right reading position thereto in conjunction with the light image reflector also adjustably positioned angularly with respect thereto for reflecting the light image of the subject copy from the copyboard through the lens on the film mounted on the film holder for a right reading shot. The copyboard is also provided with a drop down door for loading film when being used for back lighting or projection.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 314 words
A graphic arts camera for selectively producing right and wrong reading shots of a subject to be reproduced, comprising an overhead frame having a pair of parallel extending rails, a copyboard having a frame disposed in a vertical plane, roller means on said copyboard frame engaging said rails for traveling thereon, said copyboard having a pair of panels for holding subject copy pivotally mounted on said copyboard frame for swinging from a vertical plane shooting position to a horizontal plane loading position, light source means pivotally mounted on either side of said copyboard frame for illuminating subject on said copyboard, lens means disposed in a vertical plane in spaced relation to said copyboard for focussing a light image of subject copy on said copyboard, a film holder frame disposed in a vertical plane in spaced parallel relation to said lens means and said copyboard, said film holder frame having roller means engaging said overhead rails for traveling thereon for adjusting the space between said film holder frame and said lens means, a film holder pivotally mounted in a vertical axis on said film holder frame and being disposed in a vertical plane for swinging from a parallel wrong reading position to a vertical right reading position of 90* with respect to said copyboard, a carriage having roller means engaging said overhead rails for traveling thereon for adjusting the space between said carriage and said film holder, light image reflecting means pivotally mounted in a vertical axis on said carriage and being disposed in a vertical plane for being adjustably set from a parallel position to an angular position of 45* with respect to said film holder being angularly positioned at 90* for reflecting a light image from said lens means to said film holder when in the vertical right reading position thereby producing a right reading shot of the subject copy on said copyboard.
Claim 2
Dependent Claim 314 words
A graphic arts camera for selectively producing right and wrong reading shots of a subject to be reproduced, comprising an overhead frame having a pair of parallel extending rails, a copyboard having a frame disposed in a vertical plane, roller means on said copyboard frame engaging said rails for traveling thereon, said copyboard having a pair of panels for holding subject copy pivotally mounted on said copyboard frame for swinging from a vertical plane shooting position to a horizontal plane loading position, light source means pivotally mounted on either side of said copyboard frame for illuminating subject on said copyboard, lens means disposed in a vertical plane in spaced relation to said copyboard for focussing a light image of subject copy on said copyboard, a film holder frame disposed in a vertical plane in spaced parallel relation to said lens means and said copyboard, said film holder frame having roller means engaging said overhead rails for traveling thereon for adjusting the space between said film holder frame and said lens means, a film holder pivotally mounted in a vertical axis on said film holder frame and being disposed in a vertical plane for swinging from a parallel wrong reading position to a vertical right reading position of 90* with respect to said copyboard, a carriage having roller means engaging said overhead rails for traveling thereon for adjusting the space between said carriage and said film holder, light image reflecting means pivotally mounted in a vertical axis on said carriage and being disposed in a vertical plane for being adjustably set from a parallel position to an angular position of 45* with respect to said film holder being angularly positioned at 90* for reflecting a light image from said lens means to said film holder when in the vertical right reading position thereby producing a right reading shot of the subject copy on said copyboard.
Claim 3
Dependent Claim 143 words
The combination of a graphic arts camera for producing right and wrong reading shots of a subject to be reproduced, including a copyboard, lens, and a film holder disposed in vertical planes spaced longitudinally in a parallel relation to each other supporting frame means having a pair of parallel tracks, said copyboard and film holder mounted on said frame means for traveling on said tracks, said film holder comprising a supporting frame having rollers for traveling on said tracks, said film holder pivotally mounted on a vertical axis on said supporting frame for swinging to an angular position of 90* thereto, a carriage having roller means mounted on said tracks for traveling thereon, and a light image reflector pivotally mounted in a vertical axis on said carriage for being angularly positioned at 45* with respect to said film holder for right reading shots.
Claim 4
Dependent Claim 143 words
The combination of a graphic arts camera for producing right and wrong reading shots of a subject to be reproduced, including a copyboard, lens, and a film holder disposed in vertical planes spaced longitudinally in a parallel relation to each other supporting frame means having a pair of parallel tracks, said copyboard and film holder mounted on said frame means for traveling on said tracks, said film holder comprising a supporting frame having rollers for traveling on said tracks, said film holder pivotally mounted on a vertical axis on said supporting frame for swinging to an angular position of 90* thereto, a carriage having roller means mounted on said tracks for traveling thereon, and a light image reflector pivotally mounted in a vertical axis on said carriage for being angularly positioned at 45* with respect to said film holder for right reading shots.
