Title: Print head
Inventor: HAMAMOTO SHINICHI
IPC: B41J29/377
Filed: 1992-05-21
Abstract: PURPOSE:To enable an improvement in radiation properties even if a heat sink is not made and make fitting easy, by a method wherein an annular silicone rubber is provided on an outer circumference of a coil wound around a magnetic path. CONSTITUTION:When a current is applied to a coil 2, an armature 3 is attracted by a magnetic path 1, the tip part of a printing wire 8 hits a printing form by movement of the armature 3 through an ink ribbon, through which printing is performed. The armature 3 which has performed printing is returned to a position where the same comes into contact with a stopper 5 by a return spring 4 and prepares for the next printing operation. Although a heat sink 6 is provided to radiate heat to be generated on the coil 2 by the printing operation, an annular silicone rubber 7 is provided on an outer circumferential part of the coil 2 to improve radiation properties further. With this construction, the heat to be generated on the coil 2 can be transmitted efficiently to the heat sink 6 and it becomes unnecessary to enlarge the heat sink 6.
