Abstract
A mechanical pencil with automatic lead advance in which a slider is temporarily locked at the time when a rearward thrust applied to the pencil tip is released. The slider is locked by an arrangement in which a movable locking tube is disposed around the slider. The locking tube can be inclined relative to the longitudinal axis of the pencil by a spring device so that the slider, when retracted, can be temporarily locked by the inclination of the locking tube.
