Abstract
Abstract A printer unit for selectively printing on documents fed between a matrix printer and a rotatable inked platen. The platen is actuably movable between a retracted position and an advanced print position. The document while being printed upon is moved at the same speed as the velocity of the periphery of the rotating platen. The document feed is limited by a feed control roller cooperating with a pressure roller. The feed control roller is coaxial with the rotatable platen and is adapted to move therewith between the retracted position and the print position. A solenoid is provided to move the feed control roller and platen between the two positions. The documents are permitted to pass through the print station unimpeded when the roller platen and feed control roller are retracted.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
143 words
Apparatus for selectively printing information onto documents moving past a print location comprising: a. selectively actuable impact producing means; b. rotatable impact receiving means shiftable between a retracted position and an advanced print position; c. means for shiftably supporting said impact receiving means; d. means for controlling the speed of said documents moved past the print location including (1) feed roller means supported by said shiftable supporting means, and (2) pressure roller means cooperable with said feed roller means to pinch the documents therebetween when said impact receiving means is in the advanced print position, said feed roller means and said impact receiving means being mounted for conjoint rotation on said shiftable supporting means; and e. means for shifting said shiftable supporting means, to shift said impact receiving means and said feed roller means between said retracted position and said advanced print position.
Claim 2
Dependent Claim
143 words
Apparatus for selectively printing information onto documents moving past a print location comprising: a. selectively actuable impact producing means; b. rotatable impact receiving means shiftable between a retracted position and an advanced print position; c. means for shiftably supporting said impact receiving means; d. means for controlling the speed of said documents moved past the print location including (1) feed roller means supported by said shiftable supporting means, and (2) pressure roller means cooperable with said feed roller means to pinch the documents therebetween when said impact receiving means is in the advanced print position, said feed roller means and said impact receiving means being mounted for conjoint rotation on said shiftable supporting means; and e. means for shifting said shiftable supporting means, to shift said impact receiving means and said feed roller means between said retracted position and said advanced print position.
Claim 3
Dependent Claim
16 words
Apparatus as defined in claim 1 in which said impact receiving means comprises an inked platen.
