Namely, the reflected beam is not widely swayed on the light-receiving surface of a photodetector for detecting an error. Thus, the photodetector does not need to be formed especially long, and the lowering of the error detection accuracy can be prevented.

Title: Weight sensing device for cooking apparatus
Inventor: SUZUKI TOSHIAKI
IPC: A47J27/00
Filed: 1989-05-18
Abstract: PURPOSE:To protect a leaf spring against overloading by fixing one end of the leaf spring to a chassis secured to a cooking apparatus, mounting a table at the other end, and allowing the table and chassis to contact the leaf spring when it deflects according to the load applied to the table. CONSTITUTION:An inner pan 7 accommodating rice to be boiled is placed on a heater 8, and the weight of the rice acts on the center of a table to cause displacement of a leaf spring 2 downward in compliance with the load. This displacement lessens the clearance between a chassis 1 and the table 3, which contact with each other when the load exceeds a certain value, and the leaf spring 2 will no more be displaced. Therefore the leaf spring 2 will not be displaced further even in the event of overloading, which prevents deformation. This accomplishes enhancement of the accuracy in sensing the weight in simple constitution.
