Abstract: An inclination of a weighing apparatus is automatically detected by the apparatus itself while preventing an increase in the number of components. In order to achieve the object described above, a weighing apparatus includes a weight sensor, a built-in weight to be loaded on the weight sensor, an adding/removing unit for adding/removing the built-in weight, a memory storing a theoretical value of the built-in weight, and an arithmetic processing unit, wherein the arithmetic processing unit includes an inclination angle computing unit configured to obtain an apparatus inclination angle from an arc-cosine of a weighing value of the built-in weight and the theoretical value of the built-in weight.

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.

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.
