Abstract
The scale of the present invention has a housing with a recess in its upper surface to allow rotative movement of a pointer therein. Numerals corresponding to weight are disposed an an annular disc-shaped dial carried by the upper periphery of the housing. A transparent cover plate overlies the recess in which the pointer rotates. The recess, pointer and dial are arranged and dimensioned so that the pointer and numerals can be easily read by a user from a standing position. The dial and cover are flush with the outer edge of the housing so that the entire upper surface of the scale is easy to clean and comfortable.
