１２）。そして、保護装置１の光電装置２によって、欄干上縁部外側への利用者の身体の乗り出しを検出する（ステップ１２）。検出無しの場合は、ステップ１１に戻り、検出有りの場合は、ステップ１４に移行し、ブザー３によって警報する。赤外線受光装置６を介して検出信号が制御装置７に出力され（ステップ１５）、この警報後、制御装置７によって乗客コンベア９を低速運転する（ステップ１６）。タイマーが一定時間経過しているか否かを判断し（ステップ１７）、一定時間経過していなければステップ１３に戻る。一定時間経過した場合は、ステップ１８に移行し、ブザー３にて警報し、乗客コンベアを停止する（ステップ１９）。 First, in a steady operation state (step 11), the timer is reset (step 12). Then, the photoelectric device 2 of the protection device 1 detects the user's body running outside the balustrade upper edge (step 12). If there is no detection, the process returns to step 11, and if there is a detection, the process proceeds to step 14 where a buzzer 3 warns. A detection signal is output to the control device 7 via the infrared light receiving device 6 (step 15). After this alarm, the passenger conveyor 9 is operated at a low speed by the control device 7 (step 16). It is determined whether or not the timer has elapsed (step 17). If the timer has not elapsed, the process returns to step 13. If the predetermined time has elapsed, the process proceeds to step 18 where an alarm is given by the buzzer 3 and the passenger conveyor is stopped (step 19).

以上、上記実施例によれば、物体を感知する光電装置２と、この光電装置２に応動して警報を発するブザー３を有するので、利用者が保護装置に接触する前に警告を発して、保護装置１との接触を未然に防ぐことができる。   As described above, according to the embodiment, since the photoelectric device 2 that senses an object and the buzzer 3 that issues an alarm in response to the photoelectric device 2, a warning is issued before the user contacts the protective device, Contact with the protective device 1 can be prevented beforehand.
