<p><P>PROBLEM TO BE SOLVED: To effectively prevent fraudulent put-out from a ball put-out device due to each of radio waves by continuously monitoring existence of a game ball in a chute, in a game machine including a put-out ball detecting means using a magnetic proximity sensor and a ball put-out device having a driving source. <P>SOLUTION: The game machine includes: the put-out ball detecting means (77) for detecting the ball put-out from the ball put-out device (70); and upstream side ball existence detecting means (80, 82) for detecting existence of the ball on the upstream side of the ball put-out device. In the game machine, a put-out controller (200) monitors the upstream side ball existence detecting means and the put-out ball detecting means even during the put-out of the ball by the ball put-out device, and stops the put-out of the ball when a ball absence state is detected in the upstream side ball existence detecting means during the put-out of the ball by the ball put-out device or when the put-out ball detecting means does not detects a ball presence state even in the ball presence state of the upstream side ball existence detecting means. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
