Abstract

This is apparatus for changing the position of a document card so that it may be printed in a plurality of print positions and in a plurality of print rows. The apparatus includes card engaging segments disposed on the ends of flexible arms, a solenoid for flexing the arms so as to increment. the card forwardly, and a stepper motor for incrementally rotating the segments so as to step the card transversely.

Document Card Transfer Mechanism

This is apparatus for changing the position of a document card so that it may be printed in a plurality of print positions and in a plurality of print rows. The apparatus includes card engaging segments disposed on the ends of flexible arms, a solenoid for flexing the arms so as to increment. the card forwardly, and a stepper motor for incrementally rotating the segments so as to step the card transversely.

Referring to the figure, the document card printing and transport mechanism comprises, in general, a roll pair 10 for initially moving a document card 12 toward its printing position, a card inject-eject roll pair 14 for moving the card 12 just prior to and just subsequent to printing, a final roll pair 16 for moving the card after printing has been completed, a plurality of print wheels 18, a plurality of print hammers 20 corresponding to the wheels 18, a card gate 22 for holding the card 12 in an initial printing position, a pair of card clamping rolls 24 and 25, and segments 26 and 27 which coact with the rolls 24 and 25 for moving the card after initial printing has taken place. The segments 26 and 27 are formed on the ends of arms 83 and 84, which extend from and are fixed to a shaft 86. The arms 83 and 84 are of thin spring material, but the arms are relatively wide. The arms 83 and 84 are thus quite rigid in the direction of their widths, but are quite flexible in the direction in which the shaft 86 extends. The shaft 86...
