To reduce problems associated with canceling of blanking control.SOLUTION: A multi-optical axis sensor 40 has a blanking control mode in which, every time a plurality of optical paths R are blocked in order in the closing direction, the presence or absence of blocking is ignored for the optical paths R located closer to the opening direction side, including these blocked optical paths R, and in which an output of the closing operation restriction signal is turned ON or OFF depending on the presence or absence of blocking for the optical path R located closer to the closing direction side than the ignored optical path, and a normal sensing mode in which the output of the closing operation restriction signal is turned ON or OFF depending on the presence or absence of blocking for a specific normal sensing optical path among the plurality of optical paths R. During the blanking control mode, if there is a change in the presence or absence of blocking of a predetermined fully closed optical path R among the many optical paths by the closing member provided on an opening/closing body, the multi-optical axis sensor 40 switches to the normal sensing mode after a predetermined time has elapsed from the time of the change.SELECTED DRAWING: Figure 10 【課題】 ブランキング制御の解除に伴う不具合を低減する。【解決手段】 多光軸センサ４０は、複数の光路Ｒが閉鎖方向の順番で遮断される毎に、これら遮断された光路Ｒを含んで開放方向寄りに位置する光路Ｒについて遮断の有無を無視するとともに、この無視された光路よりも閉鎖方向側の光路Ｒについて遮断の有無に応じて前記閉動作制限信号の出力をＯＮ又はＯＦＦにするブランキング制御モードと、前記多数の光路Ｒのうちの特定の通常感知用光路について遮断の有無に応じて前記閉動作制限信号の出力をＯＮ又はＯＦＦにする通常感知モードとを有し、多光軸センサ４０は、ブランキング制御モードの最中、前記多数の光路のうちの所定の全閉寄り光路Ｒの開閉体に設けられた塞ぎ部材による遮断の有無の変化があった場合に、その変化時点から所定時間の経過後に通常感知モードに切替わる。【選択図】 図１０
