To inform players and spectators to make them confirm whether a ball having entered the goal in the basket game gains a normal score or not by electrically detecting each goal-in of the ball to notify the players and spectators of the results by a proper means.

A ball detection sensor 23 is disposed to detect that a basket ball normally passes through a goal ring 7 downward vertically while light- emitting bodies 18 are placed separately on the rears of a while belt 11 on the periphery part of a backboard and a white belt 12 in a shooting area. An electric light display panel 13 is erected at an upper part of the backboard and the light emitting bodies 18, the ball detection sensor 23 and the electric light display panel 13 are electrically connected with a controller interposed. When a basket ball enters a goal, both or one of the white belts 11 and 12 flashes while the electric light display panel 13 performs a display previously programmed.
