とを特徴とする電子レンジの重量検出装置。[Scope of Claim for Utility Model Registration] A support roller that supports the turntable and rotates on the bottom wall of the heating chamber is disposed inside the heating chamber, and is arranged so as to face a hole provided on the roller rotation locus on the bottom wall of the heating chamber. A force transmission body is provided, and when the roller rotates, the force of the roller is transmitted to the piezoelectric conversion element through the force transmission body, and the voltage generated in the piezoelectric conversion element is detected to calculate the weight of the object to be heated on the turntable. The weight detection device is configured to detect a voltage, and a voltage conversion means applies the output voltage of the piezoelectric conversion element to the gate of the FET, converts the drain current of the FET into a voltage, and detects a safe value of the voltage converted value. 1. A weight detecting device for a microwave oven, comprising: a weight detecting means for calculating a weight.
