ABSTRACT:
A public telephone set includes a card controller for reading information recorded in a card and performing conveyance and data processing of the card on the basis of the read information, and a speech controller for performing speech control corresponding to types of cards on the basis of data from the card controller. The card controller includes a card guide port, connected to a first convey path, for receiving plural types of cards and dispensing only a specific type of card, a return port, connected to a second convey path, for dispensing only remaining types of cards which are not dispensed to the card guide port, and a card selector mechanism for switching the cards into the first and second convey paths on the basis of a property inherent to the types of cards inserted into the card guide port, whereby charging processing corresponding to different types of cards is performed.
