Claims
- 1. In a printer including a character ring having print characters circumferentially disposed thereabout, said print characters being selectively positioned in a print position by rotation of said character ring in a first rotational direction from a rest position to a print position, the improvement comprising a detection means for generating character selection timing pulses representative of each rotational position of said character ring, said detection means further producing return timing pulses in response to the rotation of said character ring in a second rotational direction from said print position to said rest position, and print-off producing means for sensing the last said return timing pulses and in response thereto producing a print-off pulse.
- 2. A printer as claimed in claim 1, wherein said print-off pulse producing means include circuit means for sensing a time interval greater than the time interval between each said return pulse, said time interval sensing means producing said print-off pulse in response to no return pulses being applied thereto for the duration of said interval.
- 3. A printer as claimed in claim 1, wherein said print-off signal means includes means adapted to count each of said character selection timing pulses and each of said return timing pulses and in response to counting the same number of each of said pulses producing said print-off signal.
- 4. A printer as claimed in claim 3, wherein said counting means is a character counter.
