Abstract
A wire dot printing head includes armatures each of which is coupled to a printing wire, a felt guide for reducing the friction between the printing wires and a printing wire guide, a residual sheet disposed over a magnetic core frame, a biasing leaf spring, and a oil leakage preventing member. Such member is disposed over the armatures to intercept oil flowing from the felt guide. An erroneous dot printing operation due to the arms of the leaf spring sticking to the residual sheet is prevented.
