Abstract
A print head for impact type dot matrix printer having means for air-cooling the interior of the print head elevated in temperature due to the generation of heat of solenoid coils, the air cooling means is constituted in such a manner that the outer face of the print head along the direction of movement thereof is formed so as to cause the faster flow of air along said outer face when the print head is moved, and said outer face is provided with ventilating hole means which communicates the interior of the print head and the outside. When the print head is moved, it causes the faster flow along said outer face to thereby draw the air from the interior of the print head through the ventilating hole means due to the difference in pressure.
