ABSTRACT:
A writing instrument comprising an elongated hollow housing and a refill having a writing tip at one end. A cap member (50) mounted on the opposite open end of the housing can be rotated to selectively position the writing tip between a retracted storage position and an operative writing position. A feed sleeve (30) accepts the end of the refill (11) and engages in a carrier head sleeve (24) projecting into the open end of the housing. The carrier head (20) is supported on the housing in a rotatable but non-sliding manner and the feed sleeve (30) is supported interiorly of the housing in an axially displaceable and non-rotatable manner. A built-in stamp carrier is hinged to the carrier head so that it can be pivoted around an axis perpendicular to the longitudinal axis of the writing instrument between a position approximately parallel to the longitudinal axis and a position approximately perpendicular to the longitudinal axis. The carrier head (20) mounts an O-ring around its outer circumference. The cap (50) can be pushed over the O-ring in a friction-locking manner whereby torque is transmitted by rotation of said cap to position the writing tip between retracted and operative position.
