Embodiments of the present invention will now be described with reference to the drawings.

FIG. 1 is a block diagram of an example of a magnetic card type public telephone used for implementing the present invention. This magnetic card type public telephone includes all the functions of a public telephone using a publicly known telephone card, and as shown in FIG. 1, the dial circuit 1 and the card unit 5 are connected to a control circuit 2, respectively. The card unit 5 is a device that identifies and conveys the magnetic card 10, subtracts the frequency according to the call time counted by a timer (not shown), and punches the approximate frequency remaining display on the magnetic card 10. When the caller operates the dial number of the other party after inserting the magnetic card 10 into the card unit 5, this is sent from the dial circuit 1 to the control circuit 2 as a dial signal. The control circuit 2 is sequentially connected to the PB signal sending circuit 3 and the speech circuit 4. The call circuit 4 is connected to the exchange 6 via a telephone line 7. As a result, the control circuit 2
The dial signal sent to the PB signal sending circuit 3 is sent to the PB signal sending circuit 3 as a PB signal, and the PB signal sent to the PB signal sending circuit 3 is sent to the call circuit 4. This is telephone line 7
Is sent to the exchange 6 via the. The above is a known technique.

The magnetic card 10 will now be described with reference to FIG. This magnetic card 10 is, as shown in FIG. 2, a specific destination dial number 1 that is subscribed to an incoming call billing service that uses an incoming call line for free caller payment.
0a and the usage frequency of 10b, which is the same as a known telephone card
And are recorded respectively. That is, the function of a known magnetic card for limiting the number of recipients, in which only the destination dial number 10a is recorded, and the destination of any destination by dial operation,
The function of a known telephone card in which only the frequency of use 10b that is subtracted according to the degree of communication is recorded is included in one sheet.

Next, the operation of the magnetic card type public telephone shown in FIG. 1 will be described with reference to FIG.

First, a state of waiting for insertion of a magnetic card (S1)
When the magnetic card 10 is inserted into the card unit 5 from, the card unit 5 identifies whether the magnetic card 10 is normal and the remaining frequency is 1 or more (S2). If the magnetic card 10 is abnormal or the remaining frequency is zero, the magnetic card 1
0 is discharged (S3).

If the magnetic card 10 inserted in the card unit 5 is normal and the remaining frequency is 1 or more, the timer is started (S4). When the timer is started, the timer is monitored (S6) and the dial is monitored (S5). Here, if the dial number is operated within a certain period of time, the operated dial number is converted into a PB signal and sent to the exchange 6 (S
7). As a result, the magnetic card 10 can be used in the same manner as a publicly known telephone card in which only the frequency of use is recorded, and it becomes possible to talk with any destination. On the other hand, when the dial number is not operated within a certain time and the time is over, the dialed number of the callee recorded in the magnetic card 10 is converted into a PB signal and sent to the exchange 6, and the magnetic card 10 The incoming call charge connection can be made to the incoming call destination recorded in (S8). Thus, the magnetic card 10 can be used in the same manner as a known caller-only card in which only the dialed number of the callee is recorded.

After that, the same processing as the conventional magnetic card type public telephone is performed according to the PB signal sent to the exchange 6 (S9).

As described above, in this embodiment, by dialing within a certain time after inserting the magnetic card 10, it becomes possible to talk with the dial destination like a known telephone card. By magnetic card 10
You can always check to see if you can use it. As a result, if the magnetic card 10 cannot be used, the magnetic card 10 cannot be used until the magnetic card 10 is used as a publicly known caller-limited card, and it may be panicked in an emergency. Disappear. Further, switching between using the magnetic card 10 as a publicly known telephone card or as a publicly known caller-only card is carried out in the time from the insertion of the magnetic card 10 to the dial operation. For this purpose, it is only necessary to change the operation program of the magnetic card type public telephone, and no modification of the magnetic card type public telephone itself or the exchange 6 is necessary.

In this embodiment, the destination dial number 10a
Also, an example of the operation of the magnetic card type public telephone when the magnetic card 10 in which the frequency of use 10b is recorded has been described, but when a known telephone card or a known limited destination card is used. Needless to say, works like the function when each card is used.
