Title:
ELECTRONIC BALANCE
Document Type and Number:
Japanese Patent JP3487000
Kind Code:
B2
Abstract:
PURPOSE: To form the parallelism regulating mechanism of the Roverval's mechanism of an electronic balance to a mechanism having small temperature drift without zero point change.
CONSTITUTION: A Roverval's mechanism in which a fixed post 1, a movable post 2, and upper and lower parallel guides 3, 4 are coupled and the fixed post 1 is deformed by pulling the center of the post 1 to a support wall 9 by a drawing thread 10 and a set screw 11 to deform the fixed post, thereby similarly deflecting plate springs 5, 6 to vary the distance therebetween, thereby regulating the parallelism of the upper and lower parallel guides.
