ABSTRACT:
Equipment for monitoring an approach area of a moving belt apparatus (1), such as an escalator or a travelling walkway, and for controlling a drive for the belt includes light sensors (12) arranged in handrail entry caps (11) of balustrades (3). Each light sensor (12) has an emitter (15) and a receiver (16) and operates with, for example, infrared beams. The light sensors (12) monitor the access to the moving belt apparatus (1) in a specific region (13) in front of an entry to the belt (2), for example, the region of the threshold plate (14). On stepping into the monitoring region (13) of the light sensor (12), the beams emitted by the emitter (15) are reflected by the person and sensed by the associated receiver (16) to switch on the drive.
