ABSTRACT:
A daisy wheel typewriter wherein wheel positioning to present a character for printing and hammer actuation to effect printing of a selected character are electronically operated in response to keyboard generated signals. Functions associated with a printing action, e.g., ribbon lift, ribbon feed, and carriage spacing, are, however, operated mechanically in synchronism with the electronics by a timing disc driven by a print cycle function actuating shaft. Non-printing service functions are also operated mechanically by conventional powered mechanisms responsive to keyboard generated signals.
