Abstract
PURPOSE: To beforehand prevent mistakes in printing formed in the case when a printing head is driven in a speed that exceeds a fixed value, by generating new detecting signals within a fixed time after a detecting portion material of a positional generating means generates detecting signals.
CONSTITUTION: If there happens instantaneous service interruption when a printing head 3 is driven at a fixed speed, a synchronous motor 13 for driving the printing head 3 is decelerated in a moment, a sudden jacking phenomenon is immediately produced by the recovery of instantaneous service interruption, and the printing head 3 is driven in an instant in a speed that exceeds a fixed value. Since the spacing of detecting signals A becomes narrower than spacing during a fixed speed because of the instantaneous rise of the synchronous motor 13, the next signals A are generated during the time when a condition of the output signals F of a one-shot multivibrator 19 does not return, and output signals G for error signals are put out from an AND gate 20. Thus, a centralized processor 12 immediately works so as to interrupt printing operation at a point of tim when the signals A are generated.
