To improve the convenience of users in the card public telephone set.
When a card is inserted into a card reader 6 of the public telephone set, a switch SW is closed, resulting in that a latching relay RL is driven by stored charges in a capacitor C2, a contact r1 is closed, and a station power supply is supplied to each section of the telephone set. When a CPU 1 is started at the application of power, the CPU 1 reads remaining call units of the card and displays the result on a display section 5. When a user confirms the remaining call units of the card from the displayed state and makes dilaling, a dial signal corresponding to it is sent to a line to call an opposite party. Thus, it is not required for the user to insert the card or to make dialing, while having a handset in his hand in the case of making dialing to the opposite party, thereby enhancing the convenience of the users.
