摘要： A mechanical pencil incrementally rotates a lead by operation of a touch button. The pencil has a barrel in which is disposed a holder. A rotatable pipe having a writing mechanism assembly incorporated therein is attached rotatably to the holder. Around the periphery of the holder, a slide member is disposed to undergo forward and rearward movement, and the slide member is moved forward by pressing the touch button disposed on the barrel. The holder houses a sleeve which is moved forward by the slide member and which turns in a circumferential direction. A rotation-transmitting cam face is provided on each of a front end face of the sleeve and a rear end face of the rotatable pipe. By the forward movement of the sleeve, the cam faces are engaged with each other to incrementally rotate the rotatable pipe, whereby the lead is incrementally rotated.

摘要： A chuck (4) for grasping a writing lead and a rotor (6) arranged to be movable in a direction of rotation and an axial direction within a body cylinder (1) are provided. By axial movement of the rotor in conjunction with writing operation, the rotor rotates and the writing lead is also subjected to rotational movement. The writing lead can be inched out of the chuck by way of knock operation of the knock cover (26) arranged at a rear end port ion of the body cylinder. A separation part having a gap (G) is formed at any location along a knock operation transmitting path between the above-mentioned knock cover and the above-mentioned chuck, the separation part transmits the above-mentioned knock operation to the above-mentioned chuck and inhibits rotation operation from being transmitted.According to the above-mentioned structure, as the rotor and the knock cover are separated in a direction of rotation, it is possible to solve the problem of placing an obstacle to a rotational drive mechanism.
摘要翻译：提供一种用于抓取书写用引线的卡盘（4）和设置成能够在主体滚筒（1）内沿旋转方向和轴向移动的转子（6）。通过转子的结合书写操作的轴向移动，转子旋转并且书写引线也受到旋转运动。写引线可以通过布置在主体筒的后端端口处的敲击盖（26）的敲击操作而从卡盘中脱出。具有间隙（G）的分离部形成在上述敲击盖与上述卡盘之间的敲击操作传递路径的任何位置，分离部将上述的敲击操作传递到上述卡盘并且禁止旋转操作被传送。根据上述结构，由于转子和敲击盖在旋转方向上分离，因此可以解决将旋转驱动机构设置障碍物的问题。

摘要： A mechanical pencil assembly including an eraser detachably secured to the writing end thereof, said eraser defining a bore therethrough, diameter of said bore larger than the diameter of the writing tip of said mechanical pencil such that said writing tip can be projected therethrough when writing is desired and retracted therefrom when erasure is desired. The need for a user to adjust his or her grip of the mechanical pencil assembly to transition from writing to erasure or from erasure to writing is completely eliminated, making both transitions nearly immediate and nearly effortless. A further feature of the present invention is a first storage compartment disposed within said barrel wherein additional pencil leads can be stored and a second storage compartment disposed within said barrel wherein additional erasers can be stored.

摘要： A mechanical pencil for automatic drawing machines is disclosed which feeds lead segments to the writing surface as the pencil is alternately pressed against and lifted from the writing surface. The pencil includes a housing having a reserve lead containment chamber and a main internal cavity. A collet split into two portions is mounted within the internal cavity beneath an opening between the main cavity and the containment chamber and has outer cone-shaped camming surfaces and first and second axially spaced, cylindrical inner clamping surfaces. A friction tube with an inner bore adapted to frictionally engage a lead segment is mounted beneath the collet and holds a lead segment to support it against the writing surface. When the tip of the friction tube is pressed against a writing surface, the friction tube pushes upwardly on a return spring which in turn drives a collet closing bushing against the bottom surface of the collet portions, driving the outer conical camming surfaces of the collet into contact with an abutment shoulder within the cavity to drive the collet portions together such that the first and second clamping surfaces engage and hold the lead segment. When the pencil is lifted from the writing surface, the pressure on the collet is released and the collet portions separate to allow the lead segment therein to be drawn downwardly by the friction tube.
摘要翻译：公开了一种用于自动拉丝机的自动铅笔，当铅笔被交替地按压并从书写表面提升时，它将引导段馈送到书写表面。铅笔包括具有储备铅封存室和主内部空腔的外壳。分成两部分的夹头安装在主空腔和容纳室之间的开口下方的内腔内，并具有外锥形凸轮表面和第一和第二轴向间隔开的圆柱形内夹紧表面。具有适于摩擦接合引线段的内孔的摩擦管安装在夹头下方并保持引线段以将其支撑在书写表面上。当摩擦管的尖端被压靠在书写表面上时，摩擦管在复位弹簧上向上推动，复位弹簧又将夹头闭合衬套驱动抵靠夹头部分的底面，将夹头的外锥形凸轮表面驱动与空腔内的邻接肩部接触以将夹头部分驱动在一起，使得第一和第二夹紧表面接合并保持引线段。当铅笔从书写表面抬起时，夹头上的压力被释放，并且夹头部分分开以允许其中的引导段由摩擦管向下拉。

摘要： A mechanical pencil in which the lead is advanced by squeezing a cylindrical depression member provided at the position of the writer's fingers during normal writing operations. The pencil includes a hollow body with front and rear axial sleeves. A chuck is disposed within the pencil body which has a resiliency which urges the chuck to open outwardly at the front end thereof. A slider including a lead holding member for lightly holding the lead is slidably positioned at the tip of the front axial sleeve. Means is provided for transmitting movement from the depression member, which is formed of a resilient material flush with the cylindrical surface of the pencil body, for transmitting movement from the depression member to the chuck. A lead casing means is disposed in the rear axial sleeve which in some embodiments has the dual function of transmitting movement from a push button provided at the rear of the pencil to the chuck for advancing the lead in a conventional manner.

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 mechanical pencil, especially for thin leads, in which a tubular lead guide projects from and is guided for movement in axial direction in one end of a tubular casing. A resilient lead clamping arrangement is located within the casing spaced from the tubular lead guide and having clamping portions normally resiliently biased to be out of engagement with a lead passing therethrough. Transmission elements are provided between facing ends of the clamping arrangement and the lead guide to transmit, during writing and exerting of an axial pressure on the lead guide tending to move the latter into the casing, to the clamping arrangement a force which is multiplied so as to move the clamping portions of the clamping arrangement into clamping engagement with the lead, to thereby prevent inward movement of the latter during writing.
