Abstract

PURPOSE:To compulsively eliminate the busy condition and to operate the printer, by providing the time limit signal and the back up inverse line control signal generation circuit which controls the production timing of the pulse motor drive signal feeding the digit of the print head. CONSTITUTION:The busy control circuit 19 is set with the input of the start pulse SP and the busy signal is generated. Next, the time limit signal SS23 is produced with the monostable multivibrator 23, the pulse motor 1 is driven with the production of the forward pulse MFP, and after the rotation detection signal SLP-1N by the timing detector 8 is caused, the signal SS23 is fallen. If no signal SLP-1N is appeared even with the production of the signal MFP, the reverse pulse MBP is caused with the back up inversion control signal BD24 obtained with the differentiation of the trailing 24 of the signal SS23 and with the control signal SLPF/F from FF21 to eliminate the busy condition of the circuit 19. The motor 1 is given for the chance of rotation once more to the forward drive signal backed up for the drive signal generation circuit 6 with the next signal MFP input.
