Abstract
An object of the present invention is to prevent a start-up locked state from being released by a third party other than a rightful driver. After a movable bodyhas been set in a state of halted operations (a start-up locked state) by a start-up lock setting unit, a rightful driver must contact a manager on a terminal deviceside when this driver forgets a password or hands over to another driver. Having received contact, the manager transmits a start-up lock release command from the terminalside to the movable bodyvia communication units(see FIG.), whereby the state of halted operations (start-up locked state) in the movable bodyis released.
