Automatic slide door

An automatic slide door comprising

• (a) a slide rail secured to a slide door of a vehicle and extended in a fore-and-aft direction of the vehicle,
• (b) a slide rail guide holding said slide rail and held by an arm rotatably coupled to a main body of the vehicle,
• (c) a swing driving actuator for rotating said arm towards the inside or outside of the vehicle,
• (d) a slide driving actuator held by said slide rail guide and adapted for actuating said slide door and the slide rail in the fore-and-aft direction of the vehicle,
• (e) a relative position detector including a switch for detecting a changeover position at which switching is to be made between rotation of said arm and the actuation of said slide rail, and a cam arrangement for holding an operating state of said switch, and
• (f) a control unit controlling the operation of said swing driving actuator and the slide driving actuator responsive to an output detection signal of said relative position detector, said control unit causing simultaneous operation of said swing driving actuator and the slide driving actuator for a pre-set time on detection of said output signal.
