Abstract (en)
A writing instrument has a refill (2) which can axially slide in an outer casing or cylinder (1). A rotating cam set (3) is located at the rear of the refill (1) and a spring (4) biases the refill (1) rearwardly. An inertial weight (9) acts on the cam bar (8) of the cam set (3). When the writing instrument is shaken with force in excess of a given level, the weight of the moving parts functions to project and retract the refill from the outer cylinder (1) and to operate the cam set (3). The weight (9) may also act as a plunger for the manual operation of the cam set (3).
