Abstract

Abstract This invention is concerned with a photocomposing machine and is more particularly concerned with a photocomposing machine for use in preparing printing plates for use in a machine for printing business forms. In such a machine text matter is prepared on a master sheet which is mounted on a carrier which moves through the machine in such a way that the matter to be projected is correctly positioned in the photocomposing machine Mask mechanisms and also provided in the photocomposing machine and these Mask mechanisms have to be moved at the same time as the carrier. The present invention provides a memory system to record a predetermined position of the carrier and masks and hence record a position of reproduction of the representation on the sensitized material.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 73 words
A photocomposing machine comprising: a carrier for supporting documents to be reproduced; means for projecting an image of said documents for exposure on sensitized material; means for adjusting the position of said carrier to alter the position of the image on said sensitized material; means for recording the positional movements of said carrier; and means for sensing said recorded positional data to control said means for projecting said image on said sensitized material.
Claim 2
Dependent Claim 73 words
A photocomposing machine comprising: a carrier for supporting documents to be reproduced; means for projecting an image of said documents for exposure on sensitized material; means for adjusting the position of said carrier to alter the position of the image on said sensitized material; means for recording the positional movements of said carrier; and means for sensing said recorded positional data to control said means for projecting said image on said sensitized material.
Claim 3
Dependent Claim 77 words
A photocomposing machine as in claim 1 wherein said means for positioning said carrier translates said carrier in either of two directions along a given axis, said means for recording comprises a magnetic tape mounted to the housing of said photocomposing machine along at least a portion of the path traversed by said carrier and a magnetic read-write head mounted on said carrier, and said means for sensing comprises a magnetic sensing head mounted on said carrier.
Claim 4
Dependent Claim 24 words
A photocomposing machine as in claim 1 wherein said means for projecting said image includes means for selecting portions of said document for reproduction.
Claim 5
Dependent Claim 32 words
A photocomposing machine as in claim 3 wherein said means for selecting includes masking means for selectively covering and uncovering portions of said document to vary the size of the projected image.
Claim 6
Dependent Claim 47 words
A photocomposing machine as in claim 1 further comprising pulse generating means responsive to said means for sensing to generate first pulse signals representative of the recorded positional data, and wherein said means for positioning includes drive motors responsive to said pulse signals for moving said carrier.
Claim 7
Dependent Claim 29 words
A photocomposing machine as in claim 4 wherein said means for masking includes additional drive motors responsive to said pulse signals for varying the size of the projected image.
Claim 8
Dependent Claim 40 words
A photocomposing machine as in claim 6 further comprising manually operative means for generating second pulse signals and switch means for selecting either said first or said second pulse signals to energize said drive motors and said additional drive motors.
