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.

Claims

1. An automatic toll collector for a toll road comprising a cashbox inserted into a body of the toll collector for receiving coins thrown into a toll receiving inlet, a series of holes for an identification number formed in a bottom surface of the cashbox in a direction of inserting the cashbox to represent the identification number which identifies the cashbox, a series of holes for digit numbers disposed in a direction perpendicular to a direction of inserting the cashbox to represent a digit number of the identification number as a binary signal, a trigger hole for generating a trigger signal for reading the digit number to obtain a value of the digit of the identification number, a proximity sensor for the identification number disposed at a portion facing the bottom of the cashbox of the body of the toll collector for detecting a presence of the holes for the identification number, a proximity sensor for digit numbers for detecting a presence of the holes for digit numbers to read the digit number, and a proximity sensor for trigger to detect a presence of the trigger hole and generate a trigger signal, which are disposed in a line in a direction perpendicular to the direction of inserting the cashbox whereby when the cashbox is inserted into the body or is pulled out from the body, the digit number and the value of the identification number corresponding to the digit are read each time the presence of the trigger holes is detected so that the identification number of the cashbox is read.

2. An automatic toll collector for a toll road, according to claim 1, wherein said identification number is expressed by a binary-coded decimal (BCD).

3. An automatic toll collector for a toll road, according to claim 2, wherein the identification number is expressed by four digits of BCD.
