BALL SHOOTING SYSTEM CONTROL CIRCUIT AND BALL SHOOTING SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a ball shooting system which holds the number of balls that can be thrown below the predetermined numbers within predetermined time most surely. SOLUTION: A control circuit 7 has the first clock divider 71 which generates a clock signal of 2 kHz frequency using the clock signal from an oscillating circuit 8, a fundamental period counter 72 which regulates a ball throwing period using the clock signal from the first clock divider 71 and generates a timing signal by 601 msec period, and a state machine 73 which shows a coil actuator 53 current supply timing to an actuating coil 2 based on this timing signal and signals from a touch sensor 12 and a ball detection part 52.
