发明名称 Hand stamping device or writing implement
摘要 A combination hand stamp and writing instrument which has the appearance of a ball point pen of standard size and construction. The apparatus includes an easy to use indicia imprinting assembly which is conveniently housed within the upper portion of the device. The indicia imprinting assembly is movable from a retracted position into a stamping position against the urging of a novel biasing mechanism in a manner that prevents smearing and produces a clean, sharp inprint.
