Abstract

A basketball passing machine (18) includes a basketball supply (20) which provides basketballs (48) for a basketball ejector assembly (26) which passes basketballs one-at-a-time in a controlled manner along a trajectory (70) towards a waiting player. The machine can be used with a collection net assembly (16) adjacent a backboard (6) so that basketballs from both made and missed shots are collected and directed into the basketball supply. The supply of basketballs allows the passing machine to pass basketballs to the player as fast as desired, such as every three to four seconds. Balls can be passed from the machine on demand; the pass rate, the azimuth of the trajectory, the speed of the ball and the number of balls placed in play at each position can be preprogrammed. Sensors (74, 104) are used to generate signals whenever a ball is placed in play and when a shot is made. Shooting accuracy and associated information can be displayed for a player as well as recorded for future reference.

18. The machine according to claim 17, wherein said basketball ejector assembly comprises a basketball sensor at said intermediate position which senses the presence of a basketball.

19. The machine according to claim 1, further comprising means for automatically actuating said basketball ejector assembly to pass basketballs at a chosen rate.

20. The machine according to claim 1, wherein the basketball ejector assembly comprises a basketball ejector adapted pass basketballs supplied thereto along the trajectory.

21. The machine according to claim 20, wherein the basketball supply has an exit, said exit being at a higher elevation than the basketball ejector so that said basketballs move from the basketball supply to the basketball ejector by gravity.

22. A basketball passing machine and shot analysis system comprising:
