Abstract

PURPOSE:To obtain an optimum voltage applying time against the irregularity of the ON/OFF duty of a speed signal with a manual operation as a cause by setting the voltage applying time to a thermal head to the optimum value on the basis of a speed signal obtained by speed detecting means. CONSTITUTION:A feeding speed is calculated on the basis of a speed signal obtained by a speed detector 4, and a printing time of the printing period 2 of 9 is obtained by applying the feeding speed calculated by the total sum of (the processing time 1 in the printing period 1 of 8) + (printing time 1 of 11) + (waiting time 1 of 12) to (feeding speed)-(printing time curve) table. 17 basic pulse 1 of 17 is output by 16 trigger 1 of trigger signal 16 of the input of a multivibrator, and 18 basic pulse 2 is next output by trigger 2 of trigger signal 16. This operation is repeated to determine a printing time in combination of the basic pulses. In order to prevent the detector from disordering a character due to chattering at the contact with a sheet face, a printing is started after the lapse of a chattering region by inserting a suitable amount of blank from the detection of the start of printing.
