    • [Purpose] To provide a lead holding structure of a mechanical pencil where a predetermined lead holding force is maintained so that a lead does not move even if a writing pressure is repeatedly applied to the lead and where a so-called biting-off of a lead (break) is prevented without damaging the lead in repeatedly sending forward and backward operations. [Configuration] An outer periphery 5b of a chuck 5 corresponding to a lead holding section 5a is composed of a peripheral surface (horizontal surface) 5c and a peripheral surface (inclined surface) 5d. The peripheral surface 5c extends from substantially the center of the outer periphery 5b to its forward end and is substantially parallel to an axis or inclined toward the axis. The peripheral surface 5d extends from substantially the center backward and is a surface orthogonal to the axis or inclined toward the axis. The inner periphery of a fastener 6 on which the outer periphery 5b of the chuck 5 is fitted is formed as an inclined surface 6a inclined backward to the axis at a predetermined angle. When the chuck 5 is fastened with the fastener 6 while holding a lead 10, the center of the chuck 5 is a contact point 5e at which the fastener 6 and the inclined surface are in contact with each other. Further, the point at which an orthogonal line from the contact point 5e to the inclined surface and the inner periphery 5a of the lead holding section of the chuck 5 intersects is a load application point 5f in lead holding, and the load application point 5f is substantially the center of a lead holding length C.
    • [目的]提供一种自动铅笔的引线保持结构,其中保持预定的引线保持力,使得即使对引线重复施加书写压力,引线也不会移动,并且所谓的咬合 防止引导(中断),而不会导致重复发送前进和后退操作的导致。 [构造]与引线保持部5a对应的卡盘5的外周5b由外周面(水平面)5c和周面(倾斜面)5d构成。 外周表面5c从外周边5B的大致中心延伸到其前端,并且基本上平行于轴线或者朝向轴线倾斜。 外周表面5d从大致中心向后延伸,并且是与轴线正交的表面或朝向轴线倾斜的表面。 紧固件6的内周,卡盘5的外周边5b与其相配合,形成为以预定角度向轴向后倾斜的倾斜面6a。 当夹具5在保持引线10的同时用紧固件6固定时,卡盘5的中心是紧固件6和倾斜表面彼此接触的接触点5e。 此外,从接触点5e到卡盘5的引线保持部的倾斜面和内周面5a的正交线相交的点是引线保持中的负载施加点5f,负载施加 点5f基本上是引线保持长度C的中心。

    • A rechargeable battery pack attachable to a power tool includes a display element, a remaining capacity detection device, a remaining capacity display control device, an abnormality detection device, and an abnormality display control device. The display element is provided such that a lighted state thereof can be confirmed from outside. The remaining capacity detection device detects a remaining capacity of a rechargeable battery. The remaining capacity display control device displays the remaining capacity detected by the remaining capacity detection device by controlling the lighted state of the display element. The abnormality detection device detects an abnormality of the rechargeable battery. The abnormality display control device displays the abnormality of the rechargeable battery detected by the abnormality detection device by controlling the lighted state of the display element to an abnormality display state, which is different from a remaining capacity display state controlled by the remaining capacity display control device.
