Abstract
A print head has a solenoid driving means which employs a filler mixed with a lubricating oil to fix an exciting coil to the core. The filler prevents the layer winding from being shorted due to corrosion of the exciting coil and prevents mechanical abrasion of the armature by supplying lubricating oil during extended operation.
