When an object is placed on the scale, pressure acts on the sensor, and the sensor is deformed, so that the impedance changes, and at the same time, the excitation voltage changes, and the changed analog signal is output. The signal is amplified by an amplifier circuit and output to an analog-to-digital converter. It is converted into a digital signal that can be easily processed and output to CPU for operation control. The CPU outputs this result to the display according to keyboard commands and programs, and also outputs it to the portable printer to print bar code labels.
