    摘要： In a rotational drive mechanism employed for a mechanical pencil, a cam structure is simplified, the number of components is reduced, and the rotational drive mechanism is allowed to be easily assembled. A large number of cam faces 24a and 24b are continuously formed in a circle on upper and lower faces which are perpendicular to an axial direction of a rotatable cam 24 which constitutes the rotational drive mechanism 21. Elastic members 23b are formed integrally with a holder member 23 for rotatably supporting the rotatable cam 24 so as to extend in the axial direction, and the first fixed cam and second fixed cam 23c and 23d having a small number of cam faces at butts and tips of the elastic members are arranged to face each other via the upper and lower cam faces 24a and 24b of the rotatable cam 24. It is arranged that the rotatable cam 24 is retreated and moved forward in the axial direction by writing pressure applied to a writing lead so as to be rotationally driven in one direction and rotational motion of the rotatable cam 24 is transmitted to the writing lead.

    摘要： A mechanical pencil is provided having a rotational drive mechanism which gradually rotates a writing lead on application of writing pressure and allowing rotational operation of the writing lead to be known reliably. First and second cam faces 6a and 6b are respectively formed at one end face and the other end face of a rotor 6 in an axial direction, and first and second fixed cam faces 13a and 14a arranged on the body cylinder side so as to respectively face the first and the second cam faces are provided to form the rotational drive mechanism for the writing lead. A plurality of grooves 8a in the axial direction are formed at a slider 8 of a pipe end 7 which projects forwardly from a body cylinder 1. Therefore, it is possible to directly see the grooves 8a (provided for the slider 8) rotated by rotation of the rotor 6 in conjunction with the writing operation and clearly know that the writing lead is rotationally driven.

    摘要： A mechanical pencil is provided which does not require operation of removing or re-fitting a cap but allows writing immediately after supplying a writing lead. A lead fixing chuck 4 which is moved back and forth in conjunction with knock operation of a knock bar 22 to release and grip the writing lead L, and a holder chuck 9 which is provided in front of the lead fixing chuck and holds the writing lead frictionally are arranged such that the writing lead can be gradually inched out by repeating the knock operation. An open/close mechanism having an open/close valve 27 is provided in which a writing lead feeding unit is opened in a situation where the grip of the lead fixing chuck 4 on the writing lead is released by the knock operation, and the holder chuck 9 is disposed proximate to a writing lead outlet.
