Abstract: A hand writing instrument is provided with a built-in stamp (51) and built-in stamp pad (36). The stamp (51) and stamp pad (36) are respectively provided in carriers (50, 38) which are pivotally mounted on a mounting shaft (32) in such a manner that, in the rest position, the stamp (51) and stamp pad (36) lie against each other. In the working position, the stamp carrier (50) is pivoted about a position perpendicular to the mounting shaft (32) under the influence of a spring (52). Similarly, the stamp pad carrier (38) is pivoted about an approximately perpendicular position under the influence of a spring (42). The stamp carrier (50) and the stamp pad carrier (38) are movable between a stamp position and a rest position via a cap (18) which is displaceable axially with respect to the mounting shaft (32).

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.
