Writing implement for ballpoint pen and pencil with turning mechanism only when pencil is in writing position

摘要

The turning mechanism moves between three positions, in which either the tip of a ballpoint cartridge or a pencil are in writing position, or are retracted inwards.The mechanism (24) has a crank guide, which permits a press button (36) for a pencil lead to project from the rear end (34) of the implement cap (12), when in the second position. In first and third positions, the press button is withdrawn into the cap interior
