To provide a door opening/closing control device that can take a sufficient prevention measure for an erroneous operation of a door opening/closing button, which may occur due to a sudden operation.SOLUTION: A door opening/closing control device according to an embodiment is provided in an elevator device having at least a car door and a door opening/closing button and comprises a light source 121, a plurality of photoelectric conversion elements 122, a speed calculating section 23, a speed determining section 24, and a control section 26. The light source 121 is provided at one side, in a sidewise direction, of the door opening/closing button when the door opening/closing button is viewed from front. The plurality of photoelectric conversion elements 122 face the light source 121, receive light, and output current corresponding to a light receiving state. The speed calculating section 23 continuously detects changes in currents output from the plurality of photoelectric conversion elements 122 and, on the basis of the result of the detection, obtains a moving speed of an object moving between the light source 121 and the photoelectric conversion element. The speed determining section 24 determines whether the moving speed exceeds a preset threshold or not. Using the result of the determination by the speed determining section 24, the control section 26 controls an opening/closing operation.SELECTED DRAWING: Figure 2

    【課題】咄嗟時の操作で起こり得る戸開閉ボタンの誤操作に対して十分な防止対策を取ることが可能な戸開閉制御装置を提供する。【解決手段】実施形態による戸開閉制御装置は、かごドアと戸開閉ボタンを少なくとも備えるエレベータ装置に設けられ、光源121と、複数の光電変換素子122と、速度計算部23と、速度判定部24と、制御部26を備える。光源121は、戸開閉ボタンを正面から見たときに戸開閉ボタンに対して左右方向の一方側に設けられている。複数の光電変換素子122は、光源121に対向し、光を受光して受光状態に対応する電流を出力する。速度計算部23は、複数の光電変換素子122から出力された電流の変化を連続的に検出し、検出結果に基づいて光源121と光電変換素子の間を移動した物体の移動速度を求める。速度判定部24は、移動速度が予め設定されたしきい値を超えたか否かを判定する。制御部26は、速度判定部24の判定結果を用いて開閉動作を制御する。【選択図】図2
