Second, the present invention includes a circuit section for converting the signal sensed by the weight sensing device, that is, the input signal, into an electrical signal and flattening the electrical signal. The circuit section includes a circuit that converts the signal sensed by the dual weight sensing device into an electrical signal, and this circuit itself is well known. By the way, the fish held in the net jumps around in the 9M4, which causes the input signal to fluctuate irregularly, which in turn causes the electrical signal to fluctuate irregularly. As a result, the signal becomes smaller or larger depending on the weight of the fish, making it difficult to measure the weight. Therefore, in the second aspect of the present invention, a circuit for flattening an electric signal is provided in one circuit section. An example of a circuit for flattening such an electrical signal is a circuit that integrates the signal over several seconds and averages it. Alternatively, a simple example is a circuit that captures a fluctuating signal with a time delay and flattens it. In such a circuit, 0.1
