摘要： A writing instrument is capable of functioning both as an automatic mechanical pencil and as a shaking-type mechanical pencil. The writing instrument has a barrel cylinder constituted by a front cylinder detachably connected to a rear cylinder. A slider is disposed at the front end of the barrel cylinder, and a lead chuck, such as a ball chuck, is disposed rearwardly of the slider. A slider spring urges the slider forward and urges the lead chuck rearward. A lead reservoir is movably disposed rearwardly of the lead chuck. Around the outer periphery of the lead reservoir, a weight is disposed to undergo back-and-forth movement in an axial direction. On the outer periphery of the lead reservoir is disposed a weight-receiving cylinder against which the rear end of the weight abuts when the writing instrument is shaken. A knocking spring urges the weight-receiving cylinder forward and urges the lead reservoir rearward.

摘要： An automatic mechanical pencil has a tubular piece removably connected to a barrel cylinder, and a slider for frictionally holding a lead and being movably disposed in a front portion of the tubular piece. A lead chuck is disposed in the barrel cylinder for releasably holding the lead so as to allow forward movement of the lead but prevent backward movement thereof. A first spring urges the slider forward and the lead chuck backward so that when a writing front end of the writing instrument is released from a writing surface, the lead is automatically fed by urging the slider forward. A lead reservoir is disposed rearwardly of the lead chuck to supply the lead to the lead chuck. The lead reservoir has a reservoir main body, a pipe holder connected to a front end of the reservoir main body and having a guide projection, and a stopper disposed around an outer periphery of the pipe holder and having a receiving groove engageable with the guide projection. A second spring urges the reservoir main body and the stopper of the lead reservoir so that the reservoir main body and the stopper move relatively in the axial direction of the barrel cylinder.

摘要翻译： 自动自动铅笔具有可拆卸地连接到筒体的管状件，以及用于摩擦地保持引线并可移动地设置在管状件的前部中的滑块。 引线卡盘设置在筒体中，用于可释放地保持引线，以便允许引线的向前移动，但是防止其向后移动。 第一弹簧将滑块向前推动并且引导卡盘向后，使得当书写工具的写入前端从书写表面释放时，引导件通过向前推动滑块自动进给。 引线储存器设置在引线卡盘的后面，以将引线供应到引线卡盘。 铅储存器具有储存器主体，与储存器主体的前端连接并具有引导突起的管保持器，以及设置在管保持器的外周周围的止动件，并且具有可与引导突起接合的接收槽 。 第二弹簧促使储存器主体和引线储存器的止动器，使得储存器主体和止动件沿筒筒的轴向方向相对移动。
