PROBLEM TO BE SOLVED: To simplify constitution, and improve reliability by providing a needle permanent magnet of a linear synchronous motor on a plurality of doors provided on a common rail to sequentially turn on electricity to an armature winding provided on a rail. SOLUTION: A plurality of doors D is movably provided on a commonly single rail 2 of an interlocking door device 1. A needle permanent magnet piece 3 of a linear synchronous motor LM is provided on each door D. Armatures C for driving a needle are provided on the rail 2 by a space L1 of 1/2 of a width B of each door D. Each armature C is driven with servo amplifiers AMP1 to AMP24. Each door D is interlockingly opened and closed by each servo amplifier AMP by responding to detecting means S1 to S12 of a state of the door, and an opening is formed at a position corresponding to the door position of a train stopped. Accordingly, a flexible printed circuit board for feeders and signal wires need not be used by providing the armatures C along a moving route, so that generation of disconnections is lost. |
