发明名称 Football game apparatus
摘要 Balls thrown at a target are returned to a player by a combination of a moving belt and an inclined delivery surface. The belt is out of reach of the player and, when stopped, collects the balls on its upper surface, stopping the game. A timer controls movement of the belt. Sensors positioned to detect movement of a ball toward the target and through openings in the target send signals to a sign, causing the sign to present different visual displays regarding progress of the game.
