PROBLEM TO BE SOLVED: To provide a game machine where performance by an image is synchronized with performance by a performance device.SOLUTION: A game machine including game control means, a plurality of performance devices executing performance of a game by movable objects driven by driving sources, and performance control means controlling the performance devices is provided with: driving control means which controls the driving sources by an update command from the performance control means; and transmission period signal generating means which generates a transmission period signal for transmitting the update command to the driving control means from the performance control means. The driving control means takes in a data signal from a data signal line in accordance with a change of timing signal and applies an electric signal to each of the driving sources in association with the data signal. The performance control means is provided with: update command output means which outputs the update command to the driving control means by transmitting a data signal in accordance with a change of the timing signal in correspondence with generation of the transmission period signal; and update command change means which instructs a change of the update command at a timing when synchronizing with an image updating cycle. |
