It is a second weight sensor, and the conductive comb (7) has a resistance value that changes and a current value that changes in accordance with the weight applied from the mounting table (3) via the receiver part (6). . Therefore, when the food (8) is placed near the center of the table (3), almost equal weight is applied to the first and second weight sensors (4) and (5). The current value flowing through 4L (5) is almost the same, and the food (8) is
〉, the above first weight sensor (4)
When a considerable weight is added to the sensor (4), the value of the current flowing through the sensor (4) becomes considerably large, and the food item (8) is placed on the mounting table (
3), the value of the current flowing through the second weight sensor (5) becomes considerably larger. 5)
The placement position of the food (8) can be detected by looking at the current value flowing through.
