摘要： Provided is a mechanical pencil which is configured so that a rotatable cam is rotationally driven with an axis of the rotatable cam relative to a holder member stabled, and smooth operation of a rotational drive mechanism is ensured. The mechanical pencil includes a rotational drive mechanism 21 for driving rotationally a rotatable cam 23 according to writing pressure applied to a writing lead, and transfer rotational motion of the rotatable cam 23 to the writing lead. The rotational drive mechanism 21 includes a holder member 22 supporting the rotatable cam 23 so as to be rotatable, a first fixed cam 22c formed with a funnel-shaped inclined surface Fu and a second fixed cam 22d formed at an obtuse angle α relative to an axial direction. Cam faces of an upper cam 23a and a lower cam 23b alternately meshing with the first and second fixed cams are formed along a conical inclined surface Cs.

摘要： A mechanical pencil is provided which does not require operation of removing or re-fitting a cap but allows writing immediately after supplying a writing lead. A lead fixing chuck 4 which is moved back and forth in conjunction with knock operation of a knock bar 22 to release and grip the writing lead L, and a holder chuck 9 which is provided in front of the lead fixing chuck and holds the writing lead frictionally are arranged such that the writing lead can be gradually inched out by repeating the knock operation. An open/close mechanism having an open/close valve 27 is provided in which a writing lead feeding unit is opened in a situation where the grip of the lead fixing chuck 4 on the writing lead is released by the knock operation, and the holder chuck 9 is disposed proximate to a writing lead outlet.
摘要翻译：提供一种自动铅笔，其不需要去除或重新装配盖子的操作，但是在提供写入引线之后立即允许写入。引线固定卡盘4，其结合敲击杆22的敲击操作而前后移动以释放和夹紧书写引线L;以及夹持器卡盘9，其设置在引线固定卡盘的前面并保持写入引线摩擦地布置成使得写入引线可以通过重复敲击操作而逐渐脱落。提供具有打开/关闭阀27的打开/关闭机构，其中在通过敲击操作释放写入引线上的引线固定卡盘4的把手被释放的情况下，书写引线馈送单元被打开，并且保持器卡盘 9设置在书写引线出口附近。
