Abstract

PURPOSE:To enable to make a call to a specific subscriber only by dial operation of abbreviated code by writing subscriber's dial number of a person at other end of the line on a magnetic card by specified dial operation of a caller, and sending out the dial number by subsequent dial operation of abbreviated code of the caller. CONSTITUTION:When registering abbreviated dial number, a caller dial operates successively code shown in the figure, and sends out this from a dial circuit 1 to a controlling circuit 2. The controlling circuit 2 makes registration operation of abbreviated dial number, and determines a position corresponding to abbreviated code ''8'', and at the same time, writes abbreviated dial number ''03 540 9,100'' in this position. When the caller makes dial operation of code ''*8'', the controlling circuit 2 judges that it is abbreviated dial outgoing by dial signal of the first code ''*'', and receives dial signal of next code ''8'' as abbreviated code. The controlling circuit 2 determines the position to read corresponding to the abbreviated code ''8'', and reads out abbreviated dial number ''03 540 9,100'', and transmits this to a PB signal transmitting circuit 3.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a magnetic card type telephone that allows telephone calls to be made using abbreviated codes.

[Prior art and its problems]

With conventional magnetic card telephones, the number of usage points is written on the magnetic card in advance, and the number of usage points is subtracted according to the degree of the call to calculate the call charge, allowing cashless calls. It was something.

However, according to this method, the caller often has to dial the subscriber dial number of the other party to make a call, which has the disadvantage that dialing is very cumbersome when calling a large number of people at once, for example. Ta.

[Purpose of the invention]

The present invention involves writing the subscriber dial number of the other party on a magnetic card in advance when the caller performs a specific dial operation, and transmits the dial number when the caller subsequently dials an abbreviated code. It is an object of the present invention to provide a magnetic card type telephone set which eliminates the above-mentioned drawbacks and allows a telephone call to be made to a specific subscriber only by dialing an abbreviated code.

[Structure of the invention]

The configuration according to the present invention includes a control unit that receives and stores a signal generated by a caller's dial operation, and a PB signal sending means that sends out a PB double signal, and includes a subscriber dial number of the caller's other party and a corresponding number. The dial number corresponding to the abbreviated code is written on the magnetic card by a specific dialing operation including the abbreviated code, and the dial number is read from the magnetic card by the caller's subsequent dialing operation of the abbreviated code. The structure is such that the signal is read out, multiplied by PB, and sent out.

[Embodiments of the invention]

FIG. 1 is a block diagram of an embodiment of a magnetic card type telephone according to the present invention, and FIGS. 2 and 3 are charts showing an example of a dial number registration operation and a dialing operation, respectively, to be shortened.

In FIG. 1, 1 is a dial circuit, which is connected to a control circuit 2. In FIG. The control circuit 2 is sequentially connected to a PB signal sending circuit 3 and a communication circuit 4 on one side, and is connected to a card unit 5 on the other side. The text communication circuit 4 is connected to an exchange 6 via a telephone line 7.

Next, a general call operation will be explained. When the caller inserts the magnetic card 10 into the card unit 5 and then operates the dial number of the other party, the dial circuit 1 sends this as a dial signal to the control circuit 2. The control circuit 2 sends the dial signal to the PB sending circuit 3 as a PB sending signal. Therefore, the PB signal sending circuit 3 sends a PB double signal to the communication circuit 4, which is sent to the exchange 6 via the telephone line 7. Further, the control circuit 2 subtracts the frequency written on the magnetic card 10 according to the degree of communication, and calculates the remaining balance available for communication. The above is a known technique.

Next, the registration operation and calling operation of a dial number to be shortened (hereinafter referred to as abbreviated dial number) using a short code will be explained. In this embodiment, 10 speed dial numbers can be registered.

At the time of registration, the caller first dials the symbols (numbers or codes) as shown in Figure 2 in order and sends them to dial circuit 1.
from there to the control circuit 2.

The control circuit 2 receives the first symbol "0≠" in FIG. 2 and determines that a speed dial number registration operation has been designated. Then, the next symbol ``8'' is stored as a shortened code. In this case, the symbol of the shortened code is r 1.2.3
．． ..., 0'' as shown above (
It will be 10 letters. Furthermore, the control circuit 2 has the following symbol ha r 0
35409100 J is received as a speed dial number, a position corresponding to the speed dial code "8" is determined on the magnetic card 10, and the speed dial number r 035409100 J is written at this position. The registration operation is now complete.

Next, suppose that the caller then dials the symbol for "soup 8" as shown in FIG. Then, the control circuit 2 determines that it is an abbreviated dial call based on the dial signal of the first symbol "arrow". Then, the dial signal of the next symbol "8" (that is, the beginning of the symbol) is received as an abbreviated code. Therefore, the control circuit 2 determines the reading position on the magnetic card 10 in accordance with this shortened code "8". Then, the abbreviated dial number r 035409100 J corresponding to the abbreviated code "8" is read out via the card unit 5 and sent to the PE signal sending circuit 3 as a PB sending signal.

Therefore, this circuit 3 is configured to use FB in exactly the same way as in the above case.
The signal is sent to the double signal communication circuit 4.

As described above, once a caller registers a speed dial number, he or she can subsequently call a specific subscriber by dialing only two digits, which is very convenient.

Also, if you want to change the speed dial number, please
During the dial operation shown in the figure, you only need to perform the same dialing operation again as the speed dial number that you want to change, and the original speed dial number written on the magnetic card 10 will be automatically changed. is erased and a new speed dial number is written.

In the above embodiment, there are 10 abbreviated codes, but it is clear that more abbreviated codes can be set if the part of the starting point in Figure 2 is a number of two or more digits.

〔Effect of the invention〕

As explained above, according to the present invention, the subscriber dial number of the other party is written in advance on the magnetic card by the caller's specific dial operation, and the caller's subsequent dialing operation of the abbreviated code Since the above-mentioned dialed number is sent, the caller can make a call by simply dialing the abbreviated code, which has the advantage of saving the trouble of dialing, which is very convenient.
