摘要： This invention is to a writing tool such as mechanical pencil or a ballpoint pen in which a writing shaft having a head member is inserted in an outer sleeve in such a manner that the head member projects from the outer sleeve. A stair or step and a spiral groove are provided on the forward inner surface and the rearward inner surface of a tubular cap, respectively, with an inside diameter of the rear part of the spiral groove being larger. A bearing part is brought into contact with a lead tank provided inside a forward art of the tubular part so that the forward part of the outer sleeve is movable in the axial direction and is locked in the turning direction against a rearward inner surface of the outer sleeve. The rearward part of the tubular body is provided with a slit, holding pieces of a stick-shaped object holder slidably inserted in said slit. A stick-shaped object is held by the holding pieces, and the projection is provided on each holder engaged with the spiral groove of the tubular cap.
摘要翻译：本发明涉及一种诸如自动铅笔或圆珠笔的书写工具，其中具有头部构件的书写轴以使得头构件从外套筒突出的方式插入到外套筒中。分别在管状帽的前内表面和后内表面上设置有阶梯或台阶和螺旋槽，螺旋槽的后部的内径较大。使轴承部与设置在管状部的前方的内部的铅罐接触，使得外套筒的前部能够沿轴向移动，并且相对于外侧的后方内表面锁定在转动方向袖。管状体的后部设置有狭缝，可滑动地插入所述狭缝中的棒状物体保持件的保持片。一个棒状的物体由保持件保持，并且突起设置在与管状帽的螺旋槽接合的每个保持器上。

摘要： A mechanical pencil is disclosed in which lead can be advanced in one of two ways; either automatically upon release of writing pressure on the pencil, or selectively manually by pressing inwardly against a side push button. The pencil includes an outer cylinder with a side pushing hole formed therein, and a side push button movably disposed in the side pushing hole. The side push button contacts a lever which is totally mounted within the outer cylinder and which contacts a lead advanced mechanism. Upon pressing in of the side push button, the lever is pivoted about its axis and caused to press downwardly against the lead advance mechanism to thereby cause advancement of a lead. Advancement of lead is also performed upon release of writing pressure of the pencil by way of a slider mechanism which is biased outwardly by way of a resilient member and which is forced outwardly by the resilient member upon release of writing pressure. This causes the slider to pull a lead forwardly to provide advancement thereof.
