ABSTRACT:
An automatic weight detecting device is provided with a platform on which an object to be measured is placed, a supporting shaft for supporting the platform is rotatable and smoothly movable in the supporting direction. A driving motor rotates the supporting shaft, and an elastic member supports the supporting shaft. A load detecting device converts the load of the object, transmitted in the supporting direction of the rotatable supporting shaft through the elastic member into a given electrically physical amount and a weight detecting circuit integrates to obtain the average of the electrically physical amount while the shaft rotates, so that the weight of the object is detected.
