The load detector includes: first and second beam type load cells which are supported on first and second support bases in a cantilever manner to have free ends; and a mounting part on which an object is to be placed, which includes first and second connection parts connected to the first and second beam type load cells, and which is disposed between the first and second beam type load cells. The free ends of the first and second beam type load cells face opposite directions to each other in an extending direction of the first beam type load cell. The first and second connection parts of the mounting part are respectively connected to the first and second beam type load cells on a side of the free ends of the first and second beam type load cells.

Various embodiments are directed to methods and apparatuses for determining a weight of one or more objects disposed about an area of the weight measurement device using a single force sensor to accurately measure a force generated by the one or more objects. In various embodiments, the apparatus comprises a housing, a receiving tray, a lever assembly configured to receive a weight force from the receiving tray and generate a collective lever force corresponding to the weight force, the lever assembly comprising a plurality of levers, wherein each lever of the plurality of levers being at least substantially fixed to the housing at a first lever location and configured to receive a partial weight force from the receiving tray at a second lever location, and a force sensor configured to define a fulcrum point along each of the plurality of levers.
