Abstract:
A slider type mechanical pencil comprising: an outer tubular member having a front end and a rear end; an inner tubular member disposed in the outer tubular member for axial movement therein and having a lead advancement mechanism for axial movement within the outer tubular member to advance a pencil lead toward the front end of the outer tubular member; a slider having a first end portion projecting from the rear end of the outer tubular member and a second end portion, the slider extending into the outer tubular member so that the first end portion of the slider can be pressed in the axial direction relative to the outer tubular member to move the inner tubular member and the lead advancement mechanism in the axial direction toward the front end of the outer tubular member; and a pusher member extending into the outer tubular member for axial movement therein and having a first end portion projecting from the rear end of the outer tubular member and a second end portion, the pusher member extending into the slider so that in a first position of the pusher member the first end portion of the pusher member and the first end portion of the slider can be simultaneously pressed to move the inner tubular member and the lead advancement mechanism in the axial direction relative to the outer tubular member, and so that in a second position of the pusher member the first end portion of the pusher member projects from the first end portion of the slider and can be pressed to move the lead advancement mechanism in the axial direction relative to the slider, the inner tubular member and the outer tubular member to advance the pencil lead toward the front end of the outer tubular member.
