Claim:
1. A drive control system comprising: a plurality of drive control devices configured to individually control a plurality of drive devices for driving a movable body provided in a game machine; and an upper-level control device to which the plurality of drive control devices are connected in parallel with each other via a common signal line, wherein, the upper-level control device is configured to transmit a common information acquirement request signal to each of the plurality of drive control devices, and each of the plurality of drive control devices is configured to: receive the common information acquirement request signal, wherein the common information acquirement request signal includes response signal length information indicating a length of the response signal; determine a transmission start timing for a response signal based on its transmission sequence information indicating its transmission sequence and a length of the response signal such that the response signal does not temporally overlap with a response signal to be transmitted from another one of the plurality of the drive control devices to the upper-level control device; determine the length of the response signal based on the response signal length information, and determine the transmission start timing in accordance with the decided length of the response signal; and transmit the response signal to the upper-level control device via the signal line at its transmission start timing upon receiving a trigger signal from the upper-level control device.
