ッド。A dot impact printer that has a control means that reduces the printing speed or stops printing based on the output signal of a temperature detection element installed in the center of the excitation coil: In the dot print head, heat dissipation fins are formed on the outer peripheral surface and one bottom surface. At the same time, an annular hole is bored in the other bottom surface to form a protruding part in the center, and an insertion hole is further bored in the center of the protruding part to form a roughly disc-shaped heat radiator with good thermal conductivity, A flexible printed circuit board or a temperature sensing element fixed to the printed circuit board is inserted into the hole of the heat sink so as to be in contact with or close to it, and an excitation coil and a core are inserted into the annular hole so as to be in close contact with each other so as to be integrated. Features a dot print head.
