摘要

PURPOSE: To prevent the occurrence of a trouble occasioned by a use of a flexible cable by a method wherein transmission of a command to a servomotor for locking in a sliding door and supply of energy are executed through a contact device. CONSTITUTION: Energy to a servo motor 4 in a sliding door 3 is supplied through connection with energy supply contacts 11 and 12 of a control circuit 5 through a contact device 10 only when the sliding door 3 is in a closed position. A control sensor 8 is disposed corresponding to the sliding door 3 and senses the opening and closing state of the sliding door 3, and transmits the state to an electronic apparatus 6 for control through a wiring 9. The electronic apparatus 6 for control commands a locking and theft prevention position to a servo motor 4 of a sliding door 3 only when the control sensor 8 transmits a situation that the sliding door 3 is in a closed position. Simultaneously, servomotors 4 for all of other doors are operated to effect locking. A memory of the electronic apparatus 6 for control is updated each time the sliding door 3 is opened and closed.
