Claims

[Claims for Utility Model Registration] Detection means for converting impact force into an electrical signal according to the magnitude thereof, transmission means for transmitting the electrical signal from the detection means, and reception of the signal transmitted from the transmission means. The impact determining device includes a receiving means, further comprising a determining means for determining the magnitude of the impact force by comparing the signal received by the receiving means with a preset reference value, and determining the content of the determination by the determining means. A hit determination device characterized by being provided with a display means for displaying.
