Description

  The present invention relates to a weight scale having a configuration in which a measurement section and a display section are separated, and particularly to a weight scale that makes it easy to visually recognize the display of measurement results.

  Conventionally, various weight scales have been proposed. As a general scale used in homes and the like, there is one that measures weight on a pedestal. Such a weight scale normally displays a measurement result of weight on the upper surface of the pedestal.

  In such a conventional weight scale, in order to see the measurement result, it was necessary for the user to bend the body forward. However, it is a burden for a tall person or a person who tends to be obese to bend the body greatly before.

Therefore, in the weight scales described in Patent Documents 1 to 3, the pedestal portion and the display portion can be separated from each other, or the display can be performed at a position away from the pedestal portion. It is designed to improve convenience for the user.
