First Claim
Patent Images
1. An electronic scale, the improvement comprising:
- a base board made from a flat, rectangular or square plate in proper thickness, having four equal columns vertically fastened in the four corners thereof at the top;
an induction board made from a flat plate in size and shape corresponding to said base board and supported on said four equal columns above said base board;
a load board spaced from and supported on said induction board by four posts at the four corners thereof;
an inductor suspended above said base board, said inductor having a suspension end disposed right below the center of gravity of said induction board;
a pressure rod extending from the center of gravity of said induction board, said pressure rod having a free end stopped at the suspension end of said inductor;
wherein any load which is placed on said load board for weighing causes said pressure rod to move down the suspension end of said inductor and, the downward displacement of the suspension end of said inductor is calculated by an electronic circuit and converted into corresponding digital signals for display.

Abstract
An electronic weighing scale, comprising a an induction board supported on a base board by columns, a load board supported on said induction board by columns for bearing any object to be measured, an inductor suspended above said base board, a pressure rod extending from the center of gravity of said and stopped at the suspension end of said inductor, and wherein the weight of the object under measuring causes the suspension end of said inductor to displace downward proportionally and, the range of downward displacement of the suspension end of said inductor is calculated by an electronic circuit and converted into corresponding digital signals for display.
