<p>PROBLEM TO BE SOLVED: To provide a human body detector for an automatic ticket checking and collecting machine, composed of reflection type sensors having few misdetections. SOLUTION: In this human body detector for an automatic ticket checking and collecting machine, composed of reflection-type sensors each of which emit light so as to make light axes cross at prescribed height based on the height of an adult user passing through the path of the ticket gate from a pair of housing sides constituting the body of an automatic ticket checking and collecting machine provided with the path of a ticket gate between the housing sides and detects user by receiving light reflected against the user, when the emitted light hits the user, the reflection type sensors have a plurality of light beams emitted from the pair of the housing sides and are a plurality of light beams type, in which the light beams cross with each other at a different position at the prescribed height.</p> |
