ABSTRACT:
A writing appliance with a retractable stylus actuated into operating position by a reciprocable member against the bias of a spring. The stylus is latched in operating position by a slender elongated flexible member under tension, the flexible member being attached at the outer end with reciprocable member and having at the inner end a cam follower for interaction with a cam surface and a recess on a projection on the inner wall of the shell of the appliance, the flexible member remaining laterally deflected while latched. Upon subsequent reciprocation of the operating member, shaped surfaces on the cam follower and projection guide the inner end of the flexible member around the projection under the stored resilience of the flexible member and the bias of the spring. A guiding arrangement to insure interaction between the cam follower and the projection includes a key on the flexible member which snaps into a slot in the wall of the shell when the stylus is inserted into the shell.
