Abstract

PURPOSE: To elongate the life of the ribbon by detecting the slack of the ribbon, automatically controlling the tension by the detected signal, and sending the ribbon always accurately along a type belt.
CONSTITUTION: When the slack occurs in the ink ribbon 3, an actuator 11 push the ink ribbon 3 like 11'. Then a microswitch 10 is turned OFF, the resistance value of variable resistor 14 is varied to decrease by using a motor and the like through a control circuit, and the value of a driving current of a solenoid 13 of a ribbon tension adjusting mechanism 12 is increased. When the microswitch 10 is turned ON from OFF, or after the preset time from that point, the increase in the current value of the solenoid 13 is stopped. In this system, the slack in the ribbon is detected by the detecting means, the ribbon tension adjusting mechanism is operated by the detected signal, and the ribbon is always kept at the correct position along the type belt.
