摘要： 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.

摘要： A mechanical pencil with automatic lead feed has a clamping mechanism for clamping a lead in such a manner that it holds the lead steadily against rearward movement but easily permits the lead to move forwardly. A lead tube is fixed at its rear end to the front end of a housing to guide and protect the lead. A sensor is slidably held in the front end of the housing and extends along the lead tube to sense the wear of the lead during writing. A lead advancing mechanism is actuated by the sensor and has a holder for frictionally holding the lead and an elastic member for urging the holder forwardly.

摘要： A mechanical pencil 1 includes a ball chuck 11 allowing advance of the lead 7 and preventing retraction, a rotation drive mechanism 30 having a rotary part 40 and receiving an axial direction retraction operation due to writing pressure received by the lead held by the ball chuck and an axial direction advance operation due to release of the writing pressure to drive the rotary part to rotate in one direction, a feed cam face 70 having a ring-shaped cam face 62 vertical to the axial direction and an axial direction step part 71 provided at the ring-shaped cam face, and a slider 9 having an abutting part 9c abutting against the feed cam face and a holding chuck 10 holding a lead and rotating upon receiving a rotation drive force of the rotary part, which is configured so that the lead held by the holding chuck is pulled out from the ball chuck due to the advance operation of the slider when the abutting part moves along the feed cam face according to rotation of the rotary part and the abutting part falls into the drop difference.

摘要： A chuck for a mechanical pencil, wherein a lead holding part (62) is formed with several teeth (63) for use in holding the lead under four-point or six-point contacted condition. In this manner lead dust discharging regions are made. The extremity end (41) of the lead supplying cylinder is abutted against the rear raised surface (601) of the flange part (6a) from the rear end side of the lead chuck, forced applied from both directions when the front raised surface (602) of the flange part (6a) receive the rear end of the resilient member (12) installed between it and the sleeve (7) are utilized and each of the chuck members (61) generates a flexing phenomenon and then the chuck members may perform an instantaneous expanding operation under this flexing force.

摘要： The invention relates to a writing instrument, comprising a body (2), a lateral button (7) with a first cam (11) and a forwarding mechanism, having a movable member (20) with a first inclined plane (23). The lateral button (7) remains in a release position, in which the first cam faces the first inclined plane and can perform a first tilting movement, during which the first cam cooperates with the first inclined plane. Said button (7) comprises a second cam (12) which is longitudinally displaced from the first cam and the movable member has a bearing (25) which is adjacent to the second inclined plane (26). The second cam (12) is supported on the bearing during the first tilting movement and faces the second ramp at the end of said movement. The button can then perform a second tilting movement, during which the second cam cooperates with the second inclined plane.

摘要： In an automatic mechanical pencil, breakage of a lead can be prevented and a lead protruded from a slider (4) can be housed in the slider. At the frond portion of a mouthpiece, the slider is disposed movably in an axial direction. Within the mouthpiece (2), a chuck and a chuck ring (8) are provided so that an advancing movement of the lead is permitted, but a retracting movement of the lead is prevented. Between the slider and the chuck, a lead supply spring (19) is provided. The chuck ring is disposed movably in an axial direction in the mouthpiece and pressed in an axially forward direction by a writing pressure spring (24). At the rear portion of the chuck, a chuck stopper (23) is provided with a distance (22) from the rear end of the chuck. After the chuck retracts in a predetermined distance, it is stopped by a chuck stopper. Even if the retracting movement of the chuck is stopped, the slider and the lead can be housed in the mouthpiece since the chuck ring can retract by being pressed by the slider.
