PURPOSE:To facilitate manual operation by operating each driving means only when a machine number, received from a handy terminal, matches with the number of operating machine. CONSTITUTION:When a conveyor 1 stops due to malfunction, for example, under a state where it can not be operated automatically, key switch on an operating board is switched at first to OFF position thus releasing the automatic operation mode. An operator then goes to an appropriate position below the conveyor 1 and turns ON power for a handy terminal 21 and then the operator inputs a machine number. The machine number is transmitted to a controller 15. At that time, the controller 15 on the conveyor 1 side makes a self-decision whether or not the automatic operation mode is released and only when the automatic operation mode is released, the machine number transmitted on radio from the handy terminal 21 is compared with the number of its machine. If they match each other, the controller 15 operates only with a manual operation control signal delivered from the handy terminal 21. |
