Abstract
Abstract A balance combined with a computing system is capable of multiplying unit price by weight and indicating price in digital form. The price indicating balance has a computing system wherein new weight signals are successively compared with previous stored weight signals and the fluctuation of the measured weight signals due to initial oscillator motion of the weighing pan allows price calculation to start.

Claim 2
Dependent Claim
77 words
A price indicating balance comprising means for converting weight of an article to be weighed into electric information, means for introducing unit price information, means for multiplying unit price information by the converted weight information, means for detecting variations of the weight information due to initial oscillatory movement when the article is placed on the balance and also causing the multiplying operation to start by detection of said variations, and means of indicating the resulting price information.
Claim 3
Dependent Claim
33 words
A price indicating balance according to claim 1 wherein the detecting means comprises means for temporarily storing the converted weight information, and means for comparing new weight information with the stored weight information.
