Abstract
PURPOSE: To enable the measurement with good accuracy in a short time, by the constitution that the depressing force can directly be read with the heater arranging surface depressed to the specified depressing position.
CONSTITUTION: When the head unit mounting stand 42 is loaded with the thermal head unit and the motor shaft 35a is moved downward, then the upper and down moving plate 34, rod type tension gauge fitting base plate 26 and depressing plate 23 are moved downward in interlocking with it. Further, the depressing pin 22 fitted to the lower end of the depressing plate 23 is in contact with the heater arranging surface of thermal head. When the depressing plate 23 goes downward until the heater arranging surface is at the specified depressing position, the contact incorporated in the dial gauge 38 is operated and the straight line moving motor 35 is stopped. By directly reading the indicated weight of the rod type tension gauge 28 in this case, the depressing force at the specified depressing position of the heater arranging surface is clarified.
