In this automatic ticket gate, normally, when the ticket 2 is inserted through the slot 3, first the detectors 6 and 7 detect the size in the width direction, and the detection result is passed through the ticket detection circuit 54. It is taken in by the CPU 42. The ticket 2 as it is is conveyed through the conveying path 5 regardless of the front and back, and magnetic information is read by either one of the reading heads 10 and 11 provided one by one, and the magnetic information is read by the reading circuit 50 to the CPU 42. It is captured.
At this time, the CPU 42 obtains information on which side of the inserted ticket 2 is up by the read head 10 or the read head 11 that has read the magnetic information. C
The PU 42 allows the boarding ticket 2 to pass as it is or performs magnetic processing based on the captured information. For example, when magnetic processing is performed, magnetic information is written on the back surface of the ticket 2 by either one of the write heads 12 and 13 provided one by one, and the writing result is provided by the heli head 14 provided one by one. , 15 is read and confirmed. Then, the CPU 42 controls the distribution unit 22 when it determines that the boarding ticket 2 is to be punched / printed by reducing the value of the ticket 2 each time it is used in advance with a monetary value, that is, an SF card. Then, the ticket 2 is distributed to the SF processing unit 24 side. All other tickets 2 are sorted by 2
After passing through 2 as it is and subjected to scissors punching processing, etc., it is returned to the outlet 4 side or collected in the bill collecting box 40.

On the other hand, the ticket 2 distributed to the SF processing section 24 has its surfaces aligned in one direction by the reversing mechanism section 67 in accordance with the front and back sides thereof, and is directed to the standard punch 68 side in the next step by the belt 78. Be transported. A reference hole is opened according to the frequency of use of the boarding ticket 2 here, and other than that is passed through as it is.
