<p><P>PROBLEM TO BE SOLVED: To provide a highly accurate weight measuring device having reduced hysteresis by suppressing generation of friction on the sliding surface by buffering mechanically deviation of a track of a linear motion and a circular motion in a link mechanism. <P>SOLUTION: This weight measuring device is constituted from a first arm 19 mounted on a base 1 rotatably by a support pin 22, and a second arm 21 mounted rotatably by a link pin 18. In the device, guide holes 17a, 17b comprising long holes where the link pin 18 is to be inserted, provided on the base 1 for guiding the pin movably in the vertical direction, and slide holes 19a, 19b comprising long holes which are holes for inserting the link pin 18 of the first arm 19, provided so that the center lines thereof in the longitudinal direction intersect orthogonally with the center lines of the guide holes 17a, 17b in the longitudinal direction, are provided, to thereby buffer mechanically the deviation of the locus of the linear motion and the circular motion in the link mechanism. <P>COPYRIGHT: (C)2003,JPO</p> |
