<p>PURPOSE:To arrange so that the detection of the opening/closing and the locking /unlocking state of a door, and the simplification of a structure may be conducted, by detecting by means of a detecting means whether or not a minute electric current has flowed to a locking means, and giving its detection outcome to a deciding means, and discriminating the locking state of the door. CONSTITUTION:A locking/unlocking device 1, a control portion 4 provided on a car body side, a locking portion 6 provided within a slide type door and a connector 7 connected at the time of the door being closed, are equipped. Also, the control portion 4 is equipped with an operation switch 10, a processing circuit 11 which leads out the output of control in opposition to an operation from the operation switch 10, relays 12-14 conducting actions responding to the output of control and a detecting circuit 15. In addition, the corrector of a transistor Q4 is connected to the terminal B1 of the processing circuit 11 having a function as a deciding means. And a minute electric current is kept flowing through the connector 7, and the level of the terminal and B1 is kept being monitored, and thus, lines l 1a, l 2a supplying electric power to a motor 25, are made to serve the double purpose of detecting the opening/closing and the locking/unlocking state of the door 5.</p> |
