Abstract: Provided is a mass sensor including a four-corner-adjusting-mechanism capable of reducing the sensitivity of four-corner adjustment without reducing the rigidity of a Roberval mechanism. A mass sensor (1) includes a Roberval mechanism (2) in which a floating frame (21) and a fixing frame (22) are connected by upper and lower sub-frames (23, 24) having thin portions (23b) formed thereon, and a four-corner-adjusting-mechanism (4) to perform parallelism adjustment. The four-corner-adjusting-mechanism (4) includes an adjusting screw (41), and an upper elastic member (42u) and a lower elastic member (42d) disposed in series in the vertical direction so as to sandwich the sub-frame (23) to be subjected to parallelism adjustment.

Abstract: A weighing apparatus is provided that quantifies an impact load based on an electrical output from a mass sensor to prevent damage to the mass sensor by disclosing the degree of impact to a user. The weighing apparatus includes a weighing unit on which an object is placed and a mass sensor that receives the mass×acceleration of gravity of the object as a load and measures mass from an electrical signal corresponding to displacement of an internal structure of the apparatus. The apparatus quantifies and records the amount of the displacement, and determines acceleration by a numerical calculation from the displacement data. The obtained acceleration quantifies the amount of impact applied on the weighing apparatus by the object, and may be used to warn the user when the weighing apparatus is in danger of damage.

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: Provided is an overload prevention mechanism having a structure that protects a weight sensor with a floating action and ensuring the reproducibility of the return position of the weight sensor. The overload prevention mechanism has a resilient member that is interposed between the weight sensor and the case, supports the weight sensor in a pressing manner against the case, and when a certain plate load or greater is imposed causes the weight sensor to separate from the case and thereby be released from the load, a guide member that is arranged in a standing manner between the weight sensor and the case, and a guide receiving seat that is provided in the weight sensor or the case and engages with the guide member.
