ABSTRACT:
A push-button type automatic pencil includes an outer tubular member which is held in the hand of the user and lead rod holding means for holding the lead rod. A lead rod stepping means of a push button type is provided and the lead rod holding means is mounted within the outer member in such a way that the lead rod holding means is movable relative to the outer member, while still holding the lead rod, when the lead rod is pushed backward relative to the outer member. Accordingly, the breaking of the lead rod while writing is eliminated, and a soft writing feel is achieved.
