PROBLEM TO BE SOLVED: To reduce a time lag generated between drive of reels and output of a performance when the performance is output in concert with the drive of the reels.SOLUTION: Main control means 50 executes interruption processing in parallel to main processing. Before starting rotation of reels 31, a standby time producing no command is provided by the main processing and all commands stored in a buffer area 74 are transmitted to sub control means 80 by the interruption processing. After a lapse of the standby time, the rotation of the reels is started by the main processing and a rotation start command is produced and stored in the buffer area. Subsequently, the rotation start command stored in the buffer area is transmitted to the sub control means by the interruption processing. When receiving the rotation start command, the sub control means outputs a performance according to the rotation start command so as to synchronize with the rotation start of the reels. |
