PUNCH AND PRINT DATA CARD RECORDER

摘要

The disclosed data recorder includes a control cam operating to impart oscillating motions to separate punch and print actuators. The punch actuator reciprocates a punch bail to depress individual punches selected by data entry solenoids through punch interposers, thereby to perforate a data card. A step cam oscillated by the print actuator operates against print interposers coupled to the solenoids to angularly orient a print wheel, thus to imprint on the data card the data characters punched into the card. The data card is carried by a tray which is indexed through successive data entry positions in coordination with the control cam by tray stepping control apparatus. A replaceable ink cartridge supplies ink to the print wheel.
