摘要:
In a daisy wheel or rotary print wheel typewriter, a single motor is employed to accomplish both ribbon lift and feed for typewriter ribbon and correction ribbon loaded in a cartridge assembly. A single motor drive moves the cartridge assembly support about an axis to present the typewriter ribbon or the correction ribbon to the print point at the print line. When the elevation of the cartridge assembly about the axis is such to permit normal typing upon the typewriter ribbon, only the feed ratchet for the ribbon is engaged. Alternatively, when the rotation is greater, for example, for typing on the correction ribbon, the added elevation of the cartridge assembly effects disengagement of the normal ratchet feed for the typewriter ribbon while allowing advancement of the correction ribbon.
