A print head is provided with a nose that is attached to the solenoid base with a distance therebetween and that guides the needle in a longitudinally movable manner, and a heat conductor is provided between the solenoid base and the insulator in close contact with the solenoid base. A print head characterized in that a heat sink is disposed in close contact with a heat conductor. (2) The print head according to claim 1, wherein the nose is made of metal and has a contact portion that contacts the heat conductor.

Claims

[Claims for Utility Model Registration] (1) A printing head that prints by selectively protruding a plurality of needles, including an armature that pushes out each needle and a coil around which a coil that attracts the armature is wound. a solenoid base on which the plurality of coils are disposed; a printed board disposed outside the bottom surface of the solenoid base via an insulator for supplying driving current to the coils; and the insulator and the printed board. A print head is provided with a nose that is attached to the solenoid base with a distance therebetween and that guides the needle in a longitudinally movable manner, and a heat conductor is provided between the solenoid base and the insulator in close contact with the solenoid base. A print head characterized in that a heat sink is disposed in close contact with a heat conductor. (2) The print head according to claim 1, wherein the nose is made of metal and has a contact portion that contacts the heat conductor.
