ABSTRACT:
An automatic toll-ticket issuing apparatus includes a vehicle-type identification unit for identifying the type of each oncoming vehicle, a toll-ticket issuing unit installed ahead of the identification unit along the vehicle path, and a vehicle-start detector installed farther ahead of the issuing unit. The toll-ticket issuing unit has a plurality of toll-ticket issuing slots open at different heights, and it holds a stack of new, unused toll tickets. Further, the issuing unit can feed the tickets one by one out of a hopper, and it can record the vehicle-type information, interchange number, and other necessary information on each ticket being fed. The recorded tickets are sequentially transported each to an issuing slot at the height determined in response to the vehicle-type information from the vehicle-type identification unit, and any ticket left unpulled from any issuing slot by any driver can be retrieved in response to vehicle passage information.
