<p>PROBLEM TO BE SOLVED: To provide a fare receiving system capable of providing a stable communication quality even in a disturbed field distribution. SOLUTION: A level comparator compares a receiving level detected by a receiving level detector with a threshold set by a threshold set part. A timer operates at the same time when a communication is started for communication time control. A timer reset device resets a timer operation when the receiving level is judged by the level comparator to be less than a threshold allowing a communication to be established. A communication processing device receives an output from the timer and, when the communication is not completed within a specified time, regards the communication to be defective.</p> |
