Abstract

PURPOSE: To elongate the life of a wire and of space pulleys by providing an actuator which comprises an arm movable between a condition for restricting a tension arm in a predetermined position and a condition for releasing the tension arm.
CONSTITUTION: The tension applied to a space wire 4 by the force of a spring 10 and space pulleys 5 in a static condition is so selected that it is equal to the tension required for keeping a proper printing timing and a proper printing interval during the printing operation of a printing head 7. When the head 7 is moved for printing under such condition, the tension on the space wire 4 can be kept high without excessive increase of the force of the spring 10, because the solenoid 20 is deenergized and a tension is applied to the wire 4 by a tension arm 8. Accordingly, the printing timing and printing interval are decided correctly.
