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 mechanism are also provided in the photocomposing machine and these mask mechanism have to be moved at the same time as the carrier. The present invention provides means for moving the text material and means for moving the masks and means for controlling the movement of the drive mechanism to drive the text material and the masks in synchronism whereby the desired text material can be more quickly located in the required position.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
85 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 covering portions of said document for reproducing selected portions thereof; means for moving said carrier and said means for covering; and means for controlling said means for moving whereby said carrier is moved synchronously with said means for covering.
Claim 2
Dependent Claim
85 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 covering portions of said document for reproducing selected portions thereof; means for moving said carrier and said means for covering; and means for controlling said means for moving whereby said carrier is moved synchronously with said means for covering.
Claim 3
Dependent Claim
40 words
A photocomposing machine as in claim 1 wherein said means for controlling includes means for generating pulses and switching means for connecting said pulses to said means for moving said carrier and said means for moving said means for covering.
Claim 4
Dependent Claim
161 words
A photocomposing machine as in claim 2 wherein said means for covering includes a first pair of spaced mask members extending parallelly across said carrier and a second pair of spaced mask members extending parallelly across said carrier in a direction transverse to said first pair of mask members; said means for moving said means for covering includes a pulse step motor for moving each of said mask members; said means for moving said carrier includes a pulse step motor; said switching means includes a pair of relays for each of said pulse motors and an associated two-position switch for actuation of said pair of relays whereby with said associated switch in one position of said pair of relays is actuated to drive the associated step motor in one direction and with said associated switch in the other of said two positions the other of said pair of relays is actuated to drive the associated step motor in the opposite direction.
Claim 5
Dependent Claim
83 words
A photocomposing machine as in claim 3 wherein said means for controlling further includes synchronizing switch means for providing synchronous or independent control of said step motors and said switching means further includes first switch means for actuating the step motors for moving said first and second pairs of mask members independently of said step motors for moving said carrier and a second switch for actuating the step motor moving said carrier independently of said first and second pairs of spaced mask members.
