PURPOSE:To enable easy and quantitative adjustment, by forming an inlay and insert shaft part and a screw part in eccentric relation, and adjusting the up-and- down position and the left and right inclination of a thermal head by rotating the shaft of the thermal head and first and second adjusting bearings. CONSTITUTION:Two hangers 6, 6 are provided to the upper surface of the rear part of a thermal head 3 and the suspension part 11a of the thermal head shaft 11 is inserted through the insert holes 6a, 6a of said hangers. A shaft part 11e is formed to one end of the suspension part 11a and a screw part 11c and the shaft part 11e are made concentric while the suspension part 11a is made eccentric in an eccentric amount B1 with respect to the axis of the shaft part 11e. The inlay holes 14a, 14b of a first adjusting bering 14 are made eccentric in an eccentric amount B2 and the inlay and insert shaft part 15a and the screw part 15b of a second adjusting bearing 15 are made eccentric in an eccentric amount B2. By rotating the shaft 11, the up-and-down position of the thermal head can be adjusted and the left and right inclination thereof can be adjusted by rotating the adjusting bearings 14, 15. |
