Abstract
PURPOSE: To prevent pins, a ribbon and printing form from breaking by easily deciding on the abnormality of a pindriving solenoid by detecting a signal applied to a method of driving dot pins in a period of spacing between characters according to a dot pattern.
CONSTITUTION: From CPU21, the print command signal is supplied to print control part 24 and while gate 27 is opened to apply DC voltage +V to solenoids 141W147, a dot pattern that corresponds to the 1st character data stored in RAM23 is read out of ROM22, so that print data will be set up in print control part 24. Then, one of dot pins 131W137 provides dot printing. After the end of the print timing of the 1st character, sense signals from diodes 261W267 are decided and when a corresponding solenoid is activated in a space period, gate 27 is closed to cut off voltage +V to solenoids 141W147, thereby initializing pins 131W137.
