ABSTRACT:
A pencil has front and rear barrels mounted on an inner barrel. The rear and inner barrels are axially displaceable as a unit relative to the front barrel to advance a lead, and the rear barrel is angularly displaceable in opposite directions relative to the front and inner barrels to axially extend and retract an eraser. The eraser is carried by an eraser holder having projections which ride in helical grooves formed in the rear barrel, and the eraser holder is prevented from undergoing rotation. Angular displacement of the rear barrel effects axial displacement of the eraser holder so as to extend and retract the eraser depending on the direction of angular displacement of the rear barrel.
