計量器
Document Type and Number:
Japanese Patent JP5777250
Kind Code:
B2
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.
