PROBLEM TO BE SOLVED: To omit the labor of switching operation, by driving a motor to open or close the door when the sliding motion of the door is detected by an optical sensor if the opening or closing control is not executed yet. SOLUTION: A controller 87 provided with a door-opening control sliding the door by driving the door to open it and a door-closing control sliding the door by driving the door to close it, is connected to an optical sensor 84 detecting the rotary quantity and the rotary direction of a wire drum. When the opening slide motion of the door is detected by an optical sensor 84 when the door-opening control is not yet executed, the motor 8 is driven to open the door and when the closing slide motion is detected when the door-closing control is not yet executed, the motor is driven to close the door. In this way, when the manipulating operation of the sliding door is detected by the optical sensor 84, the motor is automatically rotated to the sliding direction and hence, the labor to operate a special switch is omitted. |
