    • A lead cartridge that is provided with a tank part for storing leads and is capable of being detachably connected to a receiving part provided in a lead feeding mechanism of a mechanical pencil to supply a lead can reduce costs for manufacturing the lead cartridge and the number of manufacturing steps and can prevent a lead from falling out from the lead cartridge inadvertently.The lead cartridge 10 includes a case 12 and a swing cover 14. A tank part 12a is defined inside the case 12 and the tip end part of the case 12 is formed with an open tip end connection part 12b. Between the tank part 12a and the tip end connection part 12b, a lead port 12e is formed. The swing cover 14 is mounted in the case 12 swingably to a closing position where the swing cover 14 closes the lead port 12e and to an opening position where the swing cover 14 opens the lead port 12e. The swing cover 14 includes an interfered part 14c capable of being interfered with an interference part 46e of a cartridge receiving part 46b of the mechanical pencil. The swing cover 14 is biased in a swing direction from the opening position to the closing position but swings from the closing position to the opening position when the tip end connection part 12b is fitted with the cartridge receiving part 46b so as to cause the interfered part 14c to be interfered with the interference part 46e.
    • 一种引线盒,其具有用于存储引线的容器部分,并且能够可拆卸地连接到设置在自动铅笔的引线馈送机构中的接收部分以提供引线可以降低制造引线盒的成本和数量 制造步骤,并且可以防止铅不经意地从铅盒中脱落。 引线盒10包括壳体12和摆动盖14.在壳体12的内侧形成有槽部12a,壳体12的前端部形成有开放的前端连接部12b。 在罐部12a和末端连接部12b之间形成有引出端口12e。 摇摆盖14可摆动地安装在摆动盖14关闭引导口12e的关闭位置和摆动盖14打开引导口12e的打开位置。 摆动盖14包括能够与机械铅笔的盒接收部分46b的干涉部分46e相干涉的干涉部分14c。 摇摆盖14从打开位置向关闭位置沿摆动方向偏置,但是当前端连接部12b与盒接收部46b配合时,摆动从关闭位置向打开位置摆动,从而使干涉部 14c将被干扰部分46e干扰。
