PROBLEM TO BE SOLVED: To efficiently discharge balls by providing a ball discharge control means for inputting a signal regarding the discharge of a predetermined number of lending balls based on a lending operation and a signal regarding the discharge of prize balls, and carrying out the discharge of prize balls and the discharge of lending balls through a common ball discharge unit. SOLUTION: A predetermined number of lending balls is discharged by actuating a ball discharge unit by a ball discharge unit controller 112 based on the input of a signal regarding the discharge of lending balls from a ball lending controller 108. Similarly, a predetermined number of prize balls are discharged by actuating a ball discharge unit based on the input of a signal regarding the discharge of prize balls from a premium controller 111 as a game controlling means. At that time, while the communication regarding the discharge of prize balls is carried out by one-way from the premium controller 111 to the ball discharge unit controller 112, the communication regarding the discharge of lending balls between the ball discharge unit controller 112 and the ball lending controller 108 is carried out by two-way through optical communication by a photocoupler. Priority of signals regarding the discharge of lending balls is controlled. |
