Abstract

An automatic toll collector for a toll road includes a cashbox receiving a toll thrown into a toll receiving inlet. Trigger holes, address holes and identification number holes are disposed on the bottom surface of the cashbox in a predetermined pattern in an insertion direction of the cashbox and are detected by proximity sensors disposed in the direction perpendicular to the insertion direction of the cashbox to recognize the identification number of the cashbox. Since the identification number is recognized by the correspondence between data of the address holes and data of the identification number, the identification number can be recognized exactly even if the cashbox is retried to be inserted several times.
