PURPOSE:To radiate heat to be generated from a plurality of electromagnetic coils efficiently with uniform effect of heat transfer and improve cooling effect. CONSTITUTION:A frame 3 and a radiator 1 are contacted to each other at their faces so as to improve effect of heat transfer and effect of heat radiation. Besides, the radiator is integrated with a carriage or contacted to the face thereof, so that radiation property will be improved or it can be light in weight conforming to a specification of a wire dot head. |
