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 mechanical pencil wherein a slider 11 in contact with a lead and an outer tube 1 with different frictional resistances other than a lead delivery mechanism for effecting lead-feed by general knocking operation are provided within the outer tube 1 or a fore means 2, whereby the end of a consumed lead 19 is pressed against or released from a surface of paper or the like to thereby project the lead 19 from a lead guide 12 by an amount corresponding to backward movement of the slider 11. The lead-feeding may be easily accomplished merely by pressing operation without changing the grip of the outer tube 1.

摘要： A mechanical pencil has an axially elongated hollow pencil body in which is slidable a tubular seat member. A lead-protecting sleeve is axially displaceable in the pencil body between a front position and a rear position and is urged into the front position with a relatively strong spring force. At least two jaws are axially displaceable on the seat and are moved radially closer as they move backwardly from the tip so as to grip a lead that projects backwardly from the lead-projecting sleeve. A relatively weak spring urges these jaws backwardly in the seat. An O-ring is provided in the lead-projecting sleeve so that each time the pencil tip is lifted from the writing surface the lead is automatically pulled forwardly by the strong spring force through the jaws. Similarly forward displacement of the seat in which the jaws rest allows for manual advance of a lead gripped by the jaws and passing through the lead-protecting sleeve.
摘要翻译：一种自动铅笔具有轴向细长的中空铅笔体，其中可滑动的管状座椅构件。引线保护套筒可以在铅笔本体中在前位置和后位置之间轴向移动，并以相对较强的弹簧力推动到前部位置。至少两个钳口在座椅上可轴向移动，并且当它们从尖端向后移动时，其径向更靠近地移动，以便夹持从引导突出套筒向后突出的引线。相对较弱的弹簧将这些颚向后推到座位上。在引导突出套筒中设置有O形环，使得每当笔尖从书写表面抬起时，引线将被强力弹簧力自动地向前拉过钳口。类似地，其中夹持件的座椅的向前位移允许手动前进由钳口夹持并穿过引线保护套筒的引线。

摘要： A stylus includes in a tubular casing a core body, a pressure detector that detects a pressure applied to the core body, a coupling fitted over the core body, the coupling transmitting the pressure to the pressure detector, and a core pressing controller that controls the coupling to press the core body axially in the tubular casing. The coupling includes a push bearer that bears a push from the core pressing controller, a presser having an axial end fitted in the pressure detector, a fitting region fitted over a portion of the core body remote from a pen tip end of the tubular casing, a receptacle in which another end of the presser remote from an axial end thereof is axially movably housed, and an elastic member disposed in the receptacle, the elastic member biasing the other end of the presser resiliently toward an axial pen tip end of the receptacle.

摘要： A mechanical pencil has a body with a lead storage chamber defined therein for housing spare lengths of lead, and a tubular lead guide receiving a length of lead and coaxially mounted in the body so as to partly protrude outwardly from its writing end. During writing or marking, the lead guide gradually retracts into the body against the force of a return spring with the wear of the lead received therein and, when the pencil is moved off the writing surface, it is held in place by a locking mechanism until a preselected wear point is reached, then it is sprung back to its normal position. Disposed intermediate the lead storage chamber and the lead guide, a chuck coacts with an internally tapered socket for gripping the lead against displacement away from the writing end of the body. A chuck opener member is coupled to the lead guide in order to hold the chuck open when the lead guide is in the normal position, in order to assure the uninterrupted delivery of the successive lengths of lead from the lead storage chamber into the lead guide.
摘要翻译：一种自动铅笔具有限定在其中的引线存储室的主体，用于容纳备用长度的引线，以及管状引线引导件，其容纳一段长度的引线并同轴地安装在本体中，以便从其写入端部向外突出。在书写或标记期间，引导引导件随着接收在其中的引线的磨损而逐渐退回到本体中，并且当铅笔从书写表面移开时，其通过锁定机构保持就位，直到达到预先选择的磨损点，然后将其弹回到其正常位置。在铅储存室和引导引导件之间设置一个卡盘，与内锥形插座共同作用，用于夹紧引线，使其远离本体的书写端。卡盘开启器构件联接到引导引导件，以便当引导引导件处于正常位置时保持卡盘打开，以便确保连续长度的引线从引线存储室不间断地传递到引导引导件中。

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 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.
