Electronic weighing scale using general purpose block member

A weighing scale comprising:

• an integral block member having:
• a load receiving portion for receiving a load of a scaled object;
• a fixing portion for fixing the integral block;
• and
• a Roberval portion having recessed portions between the load receiving portion and the fixing portion;
• a load transmitting beam;
• a member for transmitting displacement of the load receiving portion to the load transmitting beam and for becoming a force point of the load transmitting beam;
• a fulcrum member of the load transmitting beam;
• and
• a fulcrum member attachment portion being formed on the integral block so that the fulcrum of the load transmitting beam is positioned in a space thereby constituting the weighing scale;
• wherein the member for transmitting displacement of the load transmitting beam and fulcrum member of the load transmitting beam are formed separately from the integral block member.

A weighing scale having an integral block member, comprising:

• a support member for supporting the integral block member;
• said support member having two inside edges;
• a load transmitting member for transmitting a load to the integral block member;
• a member for directly receiving a load being connected to the load transmitting member;
• and
• reinforcing member reinforcing the support member, wherein said reinforcing member abuts the two inside edges of the support member.
