PROBLEM TO BE SOLVED: To provide an automatic ticket examination system with which the convenience is improved by using a slave equipment (adapter). SOLUTION: At the time of entrance, a slave equipment 1' transmits remained information recorded in a card 10 corresponding to an instruction from a master equipment 2' and the master equipment 2' discriminates whether an amount required for entrance is remained or not from the remainder information. When that amount is remained, an open control signal is outputted to a gate 7 and entrance station information is transmitted to the slave equipment 1' and recorded in the card 10. At the time of leaving, the slave equipment 1' transmits the remainder information and the entrance station information recorded in the card 10 corresponding to the instruction from the master equipment 2'. When the remainder has the amount previously set corresponding to the entrance station information, the master equipment 2' outputs the open control signal to the gate 7. |
