Abstract

1,204,602. Selective printing. CODAMITE CORP. 22 March, 1968,.No. 13883/68. Heading B6F. [Also in Division G4] A type member 18 may be moved axially and rotated by stepping motors 30, 32 to select a particular character, and is returned to a reference position after operation of a print hammer 26. Preferably member 18 can be retained in a letters or figures reference position by a servo system including photo-cells 60, 62 receiving light from optical fibres 64, 66 via apertures in a detent disc 52. Letter spacing is effected by stepping member 18 and hammer 26 to the right. Carriage return is performed by motors 30, 80 operating at high speed in response to a carriage return code, the occurrence of a space code in the last few character positions of a line, or unconditionally at the end of a line. The home positions of member 18 and hammer 26 are detected by photo-cells 72, 94. A line feed solenoid 112 is operated by a line feed code or a carriage return operation. The ink ribbon 28 is driven by a roller 104 which contacts an inkabsorbent roller 110, and is arranged in a Mobius loop so that upper and lower portions of each surface are used during successive passes of the loop.
