Push-button writing implement

Abstract

A push-button writing implement includes a barrel having at least a transparent or semitransparent part, a refill axially slidably contained in the barrel, and provided with a writing tip, and a refill-operating mechanism including a push button, and a return spring and designed so as to be operated by the push button to project the writing tip of the refill from a tip of the barrel and to retract the same into the barrel. A front stopper ring having the shape of an O ring is put on the refill, a fancy member is axially slidably put on part of the refill extending backward beyond the front stopper ring, and the fancy member is moved up and down along the refill when the refill is moved by resilience of the return spring by operating the refill-operating mechanism.
