ABSTRACT:
Pilot apparatus for a printer includes a program mill which can be set for printing of a character such as the numeral "3". A guide unit, to which a printing element is connected, is actuated by the program mill by way of motors or the like which are able to move the guide unit in either of two directions in two paths perpendicular to one another. The program mill includes means for actuating the motors, either individually or concurrently, to move the guide unit along the two guide paths. The actuating means include a number of cam discs mounted on a common shaft, each cam disc being programmed for a particular character to be printed. The guide unit and printing element are interconnected by a linkage system. The guide unit may include two moveable plates each including a slot. The slots cross and provide a guide point at their intersection for transferring a printing movement from the guide plates to the printing element.
