Abstract

PURPOSE:To prevent accidents or the like by providing a photoelectric device for detecting the approach of a passenger to a cage door on both sides of erect posts in a cage while providing sensors for detecting the contact of the passenger with the cage door on both sides of the cage door to output a predetermined message as a voice. CONSTITUTION:When a passenger approaches a cage door 3, a light beam from a light projecting part 5 of a photoelectric device is interrupted. A controller detects the approach of the passenger's hand (fingers or the like) from the output of a light receiving part 6 to permit a speaker 8 to output a message of an autoannounce device, for example, voice producing 'you are approaching the door, please keep away therefrom'. Further, when the passenger approaches the cage door 3 and sensors 7 detect the contact of the passenger with the cage door 3, alarming lamps 9... provided on both sides of erect posts 2 are flashed. Thus, the passenger's hand (fingers or the like) is prevented from being pinched in a gap between the cage door 3 and erect post 2 when the cage door 3 is opened.
