Abstract: Provided is a leveling mechanism for a weighing device that facilitates horizontal leveling of the weighing device. The leveling mechanism (2) includes a foot piece (10) having a foot portion (11) that in contact with an installation surface and a foot piece shaft (12) that extends upward from the foot portion and has a male screw (14) on its outer periphery, a rotatable body (20) having on its inner periphery a female screw, a housing (30) for accommodating the rotatable body engaged with the foot piece, a fixing portion (S2, 36) for fixing the housing to a device case (3), and a housing space (6) covering the housing, provided in the device case. The leveling mechanism converts a rotational motion of the rotatable body to a vertical motion of the foot piece.

Abstract: To prevent measurement errors caused by impact including an impact load transmitted at high speed or static electricity and prevent destruction of a sensor unit due to the above-mentioned impact load. Through-holes (12f) are formed in four corners of a pan receiver, upwardly protruding pieces (14a) of a plate spring fixed to a bottom surface of the pan receiver are inserted into the through-holes (12f), and pan receiver legs are attached to the upwardly protruding pieces (14a). When a pan is mounted on the pan receiver, four corners of the pan are supported by the upper surfaces of gel-like cushioning bodies and the upper ends of coil springs, impact applied to the pan including an impact load transmitted at high speed is absorbed by the gel-like cushioning bodies, and the lower ends of the coil springs contact the upwardly protruding pieces (14a) of the plate spring, so that the pan assumes a conducting state with the pan receiver via the coil springs and the plate spring, and even if the pan is charged with static electricity, the static electricity due to charging can be released to the pan receiver via the coil springs and the plate spring.

Abstract translation: 为了防止由高速或静电传递的冲击载荷引起的冲击引起的测量误差，并且防止由于上述冲击载荷而导致的传感器单元的破坏。 通孔（12f）形成在平底锅接收器的四个角部中，固定到盘接收器的底面的板簧的向上突出的片（14a）插入到通孔（12f）中，并且托盘支架腿 附接到向上突出的片（14a）。 当平底锅安装在平底锅接收器上时，锅的四个角部由凝胶状缓冲体的上表面支撑，螺旋弹簧的上端被吸收，包括高速传递的冲击载荷的包装物被吸收 通过凝胶状缓冲体，并且螺旋弹簧的下端与板簧的向上突出的片接触，使得盘经由螺旋弹簧和板弹簧与盘接收器呈现导通状态， 即使锅中充有静电，由于充电所产生的静电也可以通过螺旋弹簧和板簧释放到锅接收器。
