ABSTRACT:
A mechanical pencil in which the lead is advanced by squeezing a cylindrical depression member provided at the position of the writer's fingers during normal writing operations. The pencil includes a hollow body with front and rear axial sleeves. A chuck is disposed within the pencil body which has a resiliency which urges the chuck to open outwardly at the front end thereof. A slider including a lead holding member for lightly holding the lead is slidably positioned at the tip of the front axial sleeve. Means is provided for transmitting movement from the depression member, which is formed of a resilient material flush with the cylindrical surface of the pencil body, for transmitting movement from the depression member to the chuck. A lead casing means is disposed in the rear axial sleeve which in some embodiments has the dual function of transmitting movement from a push button provided at the rear of the pencil to the chuck for advancing the lead in a conventional manner.
