摘要： A double-chuck mechanical pencil comprises: a barrel; a barrel cap attached to the barrel; a lead tank axially slidably inserted in the barrel; a back chuck fixedly joined to the front end of the lead tank; a chuck ring loosely fitted on the chucking head of the back chuck; a tubular member disposed so as to surround the front portion of the lead tank; a back elastic member placed in the tubular member so as to bias the lead tank backward; a coupling member combined with the tubular member, and provided in its inner circumference with stopping portions with which the tubular member and the chuck ring come into contact, respectively; a front chuck fixedly joined to the front portion of the coupling member; and a front elastic member interposed between the barrel cap and the coupling member so as to bias the coupling member backward. A rotation prohibitor permits the axial movement of the coupling member and prohibits the rotation of the same relative to the tubular member. A tail cap is attached to the back end of the barrel and a push cap is detachably put on the back end of the lead tank. Another rotation prohibitor permits the axial movement of the push cap and prohibits the rotation of the same relative to the tail cap.

摘要： A bar extruding implement extrudes a bar, such as a lead, a lipstick or the like, gradually and is capable of automatically ejecting a marginal portion of the bar. A projection formed on a sliding member inserted in an inner tube slides along a helical groove formed in the inner circumference of a barrel to advance the sliding member when a rotational operating head is turned to turn the inner tube in one direction, whereby a bar holder holding a bar is advanced gradually toward the front end of the barrel to extrude the bar from the front end of the barrel. Upon the arrival of the bar holder at a disengaging position, the sliding member is disengaged from the bar holder and advances forward through the bar holder when the inner tube is turned further after the bar holder has arrived at the disengaging position to eject a marginal portion of the bar remaining on the bar holder.

摘要： A combined writing tool comprises a cylindrical casing; a push button extended from the top end of said cylindrical casing by force of a spring; a plurality of writing cartridges arranged in the casing and adapted to be alternatively extended from the bottom end of the casing through a small aperture formed therein; and a cam arranged in the casing and adapted to cause a tip of either one of the writing cartridges to be alternatively extended from and retracted in the casing through the small aperture in response to the pushing operation of the push button. The combined writing tool makes it possible to extend or retract either one of the writing cartridges from or into the casing through the small aperture only by a pushing operation of the push button. Thus easy operation can be obtained and unwanted extension of the writing cartridge can be prevented. In addition, it is possible to prevent an erroneous operation during an exchange of the writing cartridge, to enable an easy one-hand operation, to improve the reliability of the mechanism, and to reduce a size of the mechanism.
摘要翻译： 组合书写工具包括圆柱形外壳; 按钮，其由弹簧的力从所述圆筒形壳体的顶端延伸; 多个写入筒，布置在壳体中并且适于从壳体的底端通过其中形成的小孔交替地延伸; 以及凸轮，其布置在所述壳体中并且适于使得所述书写盒中的任一个的尖端响应于所述按钮的按压操作而通过所述小孔交替地延伸并且缩回到所述壳体中。 组合的书写工具使得可以仅通过按钮的推动操作通过小孔将盒子中的一个从壳体延伸或缩回到壳体中。 因此，可以获得容易的操作，并且可以防止书写盒的不期望的延伸。 此外，可以防止书写盒更换期间的错误操作，从而能够容易的单手操作，以提高机构的可靠性，并且减小机构的尺寸。
