PURPOSE:To reduce the number of component parts of printing head by a method in which a core part and a casing are integrated into one structure, and a head-radiating means is provided to the casing. CONSTITUTION:A core casing 151 is provided with a yoke 152 and a plate 153, and a core 154 is integrally formed with the plate 153. Fins 155 are also formed integrally with the yoke 152 by casing. The core assembly 127 can thus be integrated with the casing 151 by one-time casing process. By forming the core casing 151 in this way, the two parts, the core assembly and the casing, can be integrated into one part, the needs for highly accurate machining of the outer surface of the core assembly and the inner surface of the casing can be eliminated, and the cost of the printing head can be cut down. |
