Summary:PROBLEM TO BE SOLVED: To solve the problem in which: conventionally, a door closing end detection switch and a door opening end switch are prepared so as to detect a closed state of a door.SOLUTION: An encoder 5 detects driving of a door motor 4 and outputs an encoder output signal. A door control device 10 measures a door moving distance on the basis of the encoder output signal, has an arithmetic section 12 for outputting door positions of doors 2a and 2b, and controls the driving of the door motor 4 so as to control the operations of the doors 2a and 2b. An elevator control device 9 instructs the operations of the doors 2a and 2b to the door control device 10, causes the door control device 10 to operate the doors 2a and 2b to closed states, and determines the closed states of the doors 2a and 2b on the basis of a door closed state detection signal input from a door closed state detection switch 6. The elevator control device 9 determines the closed states of the doors 2a and 2b on the basis of the door positions input from the arithmetic section 12 when switching to the bypass.SELECTED DRAWING: Figure 2 【課題】従来は、ドア閉端検出スイッチ、ドア開端スイッチを用意してドアの閉状態を検出していた。【解決手段】エンコーダー5は、ドアモーター4の駆動を検出してエンコーダー出力信号を出力する。ドア制御装置10は、エンコーダー出力信号に基づいてドア移動距離を測定し、ドア2a,2bのドア位置を出力する演算部12を有し、ドアモーター4の駆動を制御することで、ドア2a,2bの動作を制御する。エレベーター制御装置9は、ドア制御装置10に対して、ドア2a,2bの動作を指示すると共に、ドア制御装置10に対してドア2a,2bを閉状態に動作させ、ドア閉状態検出スイッチ6から入力するドア閉状態検出信号に基づいて、ドア2a,2bの閉状態を判定する。また、エレベーター制御装置9は、バイパスに切替えられた場合に、演算部12から入力するドア位置に基づいて、ドア2a,2bの閉状態を判定する。【選択図】図2
