Zusammenfassung:PURPOSE:To make the size of a public telephone set small and to improve the service to the user, by discriminating the effectiveness of a card on which value information is recorded, displaying the number of residual calls during call, and displaying the value information after end of the call. CONSTITUTION:When a card on which value information such as residual number of calls is recorded is inserted, the card is discriminated by a sensor. When the card is correct, it is carried with a card carrying drive mechanism 33, recorded information is recorded 16 and the number of residual calls during call is displayed 6. After the end of call, the value information is visibly punched 18 on the card. A logic control circuit 31 enabling dial calls is provided and a carrier opening section which opens the card on the carrying path is provided. Thus, no cash box is required for the public telephone set, and troublesome operation such as throwing-in of coins one by the user is eliminated.
