Abstract

PURPOSE: To remove the anomaly of printing operation by a method in which an anomaly of operation is detected on the basis of signal generated as a motor turns and a driving signal for the motor is soon stopped immediately after being detected.
CONSTITUTION: A printer is turned ON, a motor driving signal A from a driving control circuit S is made to the state of "1", a motor MT is turned to generate signal T1 from a pulse generator PG, and even the output T2 of retrigger type one- shot multivibrator OS is made to the state of "1". When an anomaly occurs in the printer, signal T1 from PG is not generated, and when time lapses by as much as time constant t, output T2 of OS is changed to the state of "0", and the output is offered through an interface buffer VIA and line IRQ to a central arithmetic circuit CPU. At this time, in CPU, control signal D2 is made to the state of "0", the supply of signal A to MT is stopped, and the driving signal D3 of solenoid is also stopped.
