Daisy type print wheel - has print hammer adapted to impact selected element when wheel stopped

摘要

The daisy type print wheel is continuously driven through a magnetic clutch arrangement. Characters are selected by actuation of either an electromagnetic brake acting on the print wheel or a toothed character selector acting on the spokes of the print wheel. When a character is selected and the print wheel is stopped, rotation of the motor continues because of the slippage of the magnetic clutch. Other features include a fast recovery time for the hammer because of its constant rate of actuation, and change in spacing by varying this constant rate and also an improved carriage scan technique which provides for fast return.
