PROBLEM TO BE SOLVED: To provide a game ball shooting system which enlarges the selection of components and reduces the cost. SOLUTION: A game ball shooting system has a operating handle 2, a signal output part 3, a driving coil 4, a coil actuator 5, a rail 6, a supply part 7, and a control part 10 that controls the supply part 7. The control part 10 comprises an A/D converter part 11 which converts analog signals of driving current I to A/D, and an IC 12 which identifies the number of game balls 1 and controls the supply part 7 according to the power output of the A/D encoder part 11. The control part 10 comprising the A/D converter part 11 and the IC 12 does not need an IC which has A/D conversion function. As a consequence, the selection of an IC is enlarged and the cost is reduced when designing a system. COPYRIGHT: (C)2003,JPO
