ABSTRACT:
A printer carriage as for a teleprinter or a typewriter is carried on a toothed belt along a printing row, the belt being driven in forward and reverse directions by a reversible stepping motor operating without feedback. Deceleration and precise stoppage of the carriage during carriage return movements are governed by fixed signal generators along the printing row and a ring counter in the motor control unit. Stoppage occurs upon coincidence of a signal from the ring counter and a signal from a generator at the row commence position, combined in a logical AND- circuit.
