The object supply chute is placed above the dispersion section and supplies the objects to the dispersion section. The support frame supports the object supply chute. The support frame includes members (111, 113, and 114) as engaged members, hooks as engaging members that engage with the engaged members, and fixing members (140) as non-screw members. The fixing members press the engaging members against the engaged members and fix the engaging members to the engaged members.

A mass measurement device comprises a force sensor, a hose, a base part, an article-holding part, and a computation unit. The force sensor has a fixed end and a free end, and outputs a sensing signal in accordance with the magnitude of a force in a sensitivity direction. The hose is configured to pass suctioned air through it. The fixed end is fixed to the base part. The article-holding part is fixed to the free end, one end of the hose is connected to the article-holding part, and the article-holding part holds an article by air suction. The computation unit computes the mass of the article based on the sensing signal.

Disclosed is a force sensor and an apparatus having the sensor for measuring weight. The force sensor and apparatus can enhance detection sensitivity by amplifying a displacement of an elastic body having high strength, thereby measuring weight. The sensor includes: a base; an elastic structure provided as a housing disposed on the base, and downwardly deformed when weight is applied to the elastic structure; an adjusting member coupled to an upper surface of the elastic structure by penetrating the upper surface; a lever disposed below the elastic structure, and amplifying a displacement of the elastic structure transferred via the adjusting member by being in contact with the adjusting member; a sensor disposed above the base, and generating an electric signal indicative of a distance from the sensor to the lever; and a circuit board disposed between an upper surface of the base and a lower surface of the sensor.

The invention relates to a load cell for weight measurement with a load beam which has an overload protection. In order to achieve a cost-effective manufacture, it is provided that the overload protection has a bar, running parallel to the center plane of the load beam, which freely engages in a recess on the movable force application side of the load beam, with the result that there is an upper and a lower air gap between the bar and the force application side. In the case of an overload, the upper or the lower air gap is bridged and the force application side comes to rest against the bar, with the result that no further movement of the force application side relative to the stationary side of the load cell is possible.

The present invention reduces the time required by measuring a sensor object more than before. An input unit (10) includes an acquisition portion (11) that acquires a time sequence signal, a filter portion (12) that filters the time sequence signal according to a frequency, a forwarding portion (13) that forwards a filtered signal by frequency to a control device (90) and a filter switching portion (14). The filter switching portion (14) switches whether the filter portion (12) filters the time sequence signal according to a frequency in the process of acquiring the time sequence signal by the acquisition portion (11).
