1. A drive control system formed from a mechanism which arranges a plurality of magnetic bodies, and, when at least one magnetic body is driven, the drive thereof is sequentially transmitted to the other magnetic bodies without using a mechanical transmission mechanism; wherein the magnetic field generated from the drive of at least one magnetic body is magnetically coupled with the other magnetic bodies so as to synchronously drive said other magnetic bodies, the system comprising a drive control unit formed from a plurality of motors mutually arranged adjacently, wherewith said motors are structured by said magnetic bodies comprising a magnetic rotor, and which is for exciting and driving at least one of said motors; wherein said drive control unit is constituted so as to send a drive signal for driving said magnetic rotor to at least one of said motors; and the magnetic rotors of the other motors are synchronously driven by the magnetic coupling with the magnetic field generated from the excitation driven magnetic rotor.
