To provide an automatic door closing device which is compact, automatically opens or closes doors of a platform door device responding to the result of detecting an open or close state of a vehicle entrance door and neither disturbs movements of passengers nor gives them visual discomfort.SOLUTION: An automatic door closing device 1 is installed in a platform door device 2 which comprises a door pocket 4 fixed to a platform 3, a door body 5 that is supported by the pocket 4 enabling the door body to proceed and to recede freely and a drive unit that makes the door body 5 proceed to or recede from the pocket 4, and automatically closes the platform door device 2. The closing device 1 is fixed to a position nearer the track side than a lateral plate in the platform 3 side of the pocket 4 and comprises a regression reflection type photoelectric sensor 10 detecting an open or close state of the entrance door 9 of the vehicle 8 and a computer 11 enabling the platform door device 2 to close the platform door at the time when the entrance door 9 changes from an open state to a close state based on the result detected by the photoelectric sensor 10.SELECTED DRAWING: Figure 2

    【課題】車両の乗降扉の開閉状態を検知して、その結果に応じて、ホームドア装置の扉を開閉する自動閉扉装置であって、コンパクトで乗客の移動を妨げることがなく、乗客に視覚的な違和感を与えることがない自動閉扉装置を提供する。【解決手段】自動閉扉装置1は、プラットホーム3に固定される戸袋4と、戸袋4に進退自在に支持される扉体5と、扉体5を戸袋4に対して進退させる駆動装置と、を備えるホームドア装置2に取り付けられて、ホームドア装置2を自動的に閉扉する自動閉扉装置1であって、戸袋4のプラットホーム3側の側板よりも軌道側に寄った位置に固定されて、車両8の乗降扉9の開閉状態を検出する回帰反射型光電センサ10と、回帰反射型光電センサ10による検出結果に基づいて、乗降扉9の開閉状態が開状態から閉状態に変化したタイミングで、当該ホームドア装置2に閉扉動作をさせるコンピュータ11と、を備える。【選択図】図2
