PROBLEM TO BE SOLVED: To obtain function for recording a record of a game of go for reducing difficulty and complexity for preparing the record of the game of go by using go stones built-in magnets, by disposing magnetic sensors under crosses of the go board, and by transferring an existence of the go stone to process in a computer software. ;SOLUTION: When a go stone 2 having a magnet 3 magnetized to front and rear directions of the go stone therein is put on an adjacent to a cross of a non-magnetic go board 1, magnetic flux of the magnet 3 is led to a lead switch 4 for using as a magnetic sensor from an upper edge to a lower edge to operate the lead switch. One edge of the lead switch is a conductive wire 5, and is connected with one X-axis directional wire of X-axis Y-axis common conductive wires provided at every 19 lanes of the go board and the other edge is a conductive wire 6 and is connected with one wire of Y-axis directional common conductive wires through a diode for preventing from turning in. After the common conductive wires of the X-axis are scanned in turn and bit signals relating an existence of the go stone from the common conductive wires of the Y-axis are obtained and information is input to a computer to prepare the record of the game of go.;COPYRIGHT: (C)2000,JPO
