Abstract (en)
[origin: US5660106A] A printing unit has a plurality of type wheels with types on its circumference which are rotatable on a common shaft and are driveable on it by means of a slip coupling. Each type wheel has an associated feeler device that ascertains its position and a pawl for engagement with the type wheel, with an actuator that is triggerable as a function of the feeler device via a control unit, and by the actuator the pawl can be controlled between a blocking position and a release position. The drive device serving the purpose of intermittently driving the shaft has per printing unit one drive shaft, operationally coupled to the shaft, with a driving gear wheel and one common stationary disc associated with a plurality of printing units disposed in the circumferential direction. On the pitch Circle of the respective driving gear wheel, this disc has a toothed segment associated with the gear wheel, with which segment the driving gear wheel can be brought into engagement upon revolution of the printing unit and hence for the length of the setting time.
