MAN DETECTION DEVICE FOR AUTOMATIC TICKET EXAMINATION MACHINE

摘要

PROBLEM TO BE SOLVED: To precisely detect an adult user and to prevent a detection error by constituting a reflection-type sensor main body containing plural reflection- type sensors and installing them so that the arranging relations of the light emitting elements and light receiving elements of plural reflection-type sensors become opposite. SOLUTION: A reflection-type sensor main body 31 is formed of plural reflection-type sensors 3a and 3b. The reflection-type sensor 3a is formed of a light emitting element 3a1 irradiating a ticket examination path P1 with a light beam and a light t receiving element 3a2 generating current when the light beam is received. The light emitting element 3a1 is installed on an upper side and the light receiving element 3a2 on a lower side. It is decided so that the light beam reflected from an object in the size of an adult user in the ticket examination path P1 can be received. The reflection-type sensor 3b is positioned adjacently to the reflection-type sensor 3a. The light emitting element 3b1 is arranged to be on the lower side and the light receiving element 3b on the upper side, which is in the opposite position relation of the light emitting element 3a1 and the light receiving element 3a2 in the reflection-type sensor 3a.
