摘要： A lead feed mechanism for a mechanical pencil, in which a lead protruded by a certain length from a lead protection pipe housed in a bottom member attached at the bottom of the pencil is fed together with the pipe, and which comprises a lead chuck which is split in plural parts along the axis of the pencil and whose bottom sections pinch the lead on its outside circumferential surface. A sleeve contains the lead chuck so as to urge the lead chuck upwards by an elastic member. The sleeve includes an engaging portion provided on the inside circumferential surface of the top portion of the sleeve and engaged with an engaging portion provided on the outside circumferential surface of a bottom bearer for a lead pipe in which a spare lead is housed. A frame is provided around the sleeve which is fitted on the bottom with a pushing member which bears by the open top of the frame an elastic member provided between the bottom bearer and the frame. A slider is fitted in a cylindrical fixed member fixed in the bottom member so that the slider can be slid by the action of an elastic member. The top of the slider is separated at a prescribed distance from the pushing member.

摘要： A writing instrument includes a tubular body, a guide sleeve, an outer sleeve, and a holder. The outer sleeve includes at least one groove on an inner surface thereof, and the guide sleeve includes at least one rib on a forward portion thereof to engage the groove of the outer sleeve. An inclined surface continuously inclining relative to the axial direction of the outer sleeve is formed at a rearward end portion of either side wall of the groove such that a width of the groove becomes wider in a direction of the rearward end. An inclined surface continuously inclining relative to the axial direction of the outer sleeve is formed at a forward end portion of either side wall of the rib such that a width of the rib becomes smaller in a direction of the forward end. An inclined angle of the inclined surface of the groove is not less than that of the inclined surface of the rib.

摘要： In a writing utensil according to the present invention, when a rearward outer cylinder is rotated in either direction, a cam engaging projection, which is integral with the rearward outer cylinder, slides pressingly on either of the respective cam surfaces of first and second sliders. This causes one of the first and second sliders to advance, which in turn causes a first of the first and second refills to project forwardly while the other remains retracted. Similarly, when the rearward outer cylinder is rotated in the opposite direction, the cam engaging projection slides pressingly on the other of the cam surfaces of the first and second sliders. This causes advancement of the other of the sliders, and in turn causes the second of the first and second refills to be projected while the first remains retracted. The construction allows these operations to be smoothly, stably and positively performed.

摘要： A lead chuck of a mechanical pencil to be assembled into a lead feeding mechanism of a rear end knock type, an automatic lead feeding type and an extremity end knock type mechanical pencil in which it is arranged within the sleeve through a resilient member in such a way as it may be advanced or retracted. A lead holding part is formed at the extremity end portions of the divided surfaces of the chuck members which are fully divided into two sections along an axial plane. The lead holding part is formed with several teeth for use in holding the lead under four-point or six-point contacted condition within axially formed grooves made at the central portions of the divided surfaces. The teeth are projected in several rows and formed at the raised surfaces of the grooves. Stepped partial circumferential projections are projected and formed at the central part of the raised parts of the front portions of the semi-circumferential flange which are projected and formed at the outer circumference at the rear ends of the chuck members. Other stepped projections are formed at both end portions of the raised rear surfaces of the opposite sides of the flange, thereby the extremity end of the lead supplying cylinder extremity end receiving element is abutted against the rear raised surface of the flange part from the rear end side of the lead chuck. Forces applied from both directions, when the front raised surface of the flange part receive the rear end of the resilient member installed between it and the sleeve, are utilized and each of the chuck members generates a flexing phenomenon and the chuck members may then perform an instantaneous expanding operation under this flexing force.
