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： Mechanism for putting the head of a shaft into and out of the head of an outer sleeve comprised of an outer sleeve (1), a long hole (2) formed in the outer sleeve (1), and a clip (3) to be put into and out of the outer sleeve (1) through the long hole (2). A shaft (4) is inserted in the outer sleeve (1), and a cam mechanism (8) cooperates with the clip (3) in a manner that causes the cam mechanism (8) to move forward and backward in an axial direction according to in and out movement of the clip (3). A spring (6) spring-biases the shaft (4) toward the cam mechanism.

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.
