Description

Description: TECHNICAL FIELD The present invention relates to a telephone system using a telephone card, and particularly to telephone communication using a telephone card using a communication device such as a general telephone or a facsimile device. It concerns the telephone system.

(Prior Art) Conventionally, telephones that can use a telephone card have been limited to some models of public telephones.

(Problems to be Solved by the Invention) Conventionally, telephones that can use a telephone card have been limited as described above. Therefore, the owner of a communication device such as a general home telephone or a facsimile machine using the telephone card has been limited. If a person who is not
I had to ask the telephone station to count the fee for the 0th application and pay the owner the usage fee after use. Therefore, in such a case, 100 before and after using
There was a drawback that it was troublesome because it was necessary to make an inquiry about the application and the fee.

Telephone cards have come to be used as gifts today, but since only outdoor card public telephones are effective, it was necessary to go to the place where the card public telephones were installed. In particular, there is a drawback that communication devices such as facsimiles cannot be used by anyone other than the owner of the telephone.

An object of the present invention is to solve the drawback that a telephone card cannot be used for a general telephone, and to enable a general telephone and a communication device such as a facsimile connected to the general telephone to be used with the telephone card.

(Means for Solving Problems) In order to solve the above problems, in a telephone system in which a telephone card is used to perform telephone communication with a general telephone,
A telephone card adapter is provided on the telephone,
After detecting a signal sent from the telephone card adapter to the exchange side, sending a charging pulse from the general exchange circuit,
It was configured to switch to a switching circuit that receives stored signals and to perform telephone communication using a telephone card.

(Operation) By configuring the present invention as described above, by providing the telephone card adapter to the general telephone and making the switch of the line to which it subscribes have the same function as the public telephone,
The telephone card can be used as a general telephone and a communication device such as a facsimile connected to the ordinary telephone.

Example An example of the present invention will be described with reference to the drawings.

FIG. 1 is a configuration diagram of an embodiment of the present invention, and FIG. 2 is an operation flow explanatory diagram thereof.

In FIG. 1, reference numeral 1 is an exchange circuit A, and the exchange circuit A1 has a charge pulse transmission, a charge storage signal reception, a line disconnection circuit and the like. 2 is an exchange circuit B, and the exchange circuit B2 is connected to a conventional general telephone. 3 is a card signal detector, and the card signal detector 3 inserts and reads a telephone card,
The card signal sent from the telephone card adapter 6 for writing and discharging is detected. Reference numeral 4 is a switch operated by a card detector, 5 is a communication line of a telephone, 6 is a telephone card adapter, and 7 is a telephone.

Further, FIG. 2 shows an operation flow of this configuration as described above, and the operation will be described with reference to FIGS. 1 and 2.

OFF HO when using the telephone with a telephone card
After confirming OK, check the dial tone sent from the exchange side,
Insert the telephone card into the telephone card adapter 6. The telephone card adapter 6 sends a card signal to the exchange side after confirming whether the inserted card is valid. On the exchange side, when a card signal is detected by the card signal detector 3, the switching device 4 operates by the output of the card signal detector 3 and the telephone 7 is connected to the exchange circuit A1 as shown by the dotted line in FIG. To be done. The exchange circuit A1 is operated by the dial pulse from the telephone 7 and the other party is connected to be in a call or communication state. During a call or communication operation, a charging pulse corresponding to the incoming call area is sent from the exchange circuit A1 to the telephone card adapter 6, and the telephone card adapter 6 sends a stored signal to the exchange circuit A1 according to the remaining number of telephone cards already confirmed. To do. However, at this time, when the remaining number of cards is exhausted, the telephone card adapter 6 does not send a storage signal and the line is disconnected by the exchange circuit A1.

ON HOOK when the remaining number of telephone cards remains
The call or communication is continued until then, the line is disconnected at this point, and the switch 4 is restored. After that, the telephone card adapter 6 writes the remaining number after subtracting the used amount to the card and discharges it. The case where the telephone card is used with the telephone card has been described above. However, since the telephone card adapter 6 does not send a card signal when the telephone card is not used, the switching device 4 remains in the state shown by the solid line in the figure, and a normal telephone exchange It will work.

 FIG. 3 is a block diagram of another embodiment of the present invention.

FIG. 3 shows a communication device 8 such as a facsimile in the configuration of FIG.
After the line connection shown in FIG.
When the communication switch 13 is pressed, the line is switched from the telephone 7 to a communication device, and image signals and data signals are transmitted and received.

When a call is received in this configuration, the home position of the switch 4 is in the solid line state in FIG.

(Effects of the Invention) As described above, the present invention is provided with the telephone card adapter 6 in the ordinary telephone and the card signal detector 3 on the exchange side so that the ordinary telephone can be used with the telephone card. Therefore, when an unspecified person uses a telephone owned by another person as in the conventional case, the telephone can be used without applying to the number 100.

Further, the present invention can be applied not only to the use of a telephone but also to the case where another person uses a communication device such as a facsimile or a captain system.

By using a plurality of reading / writing units of the telephone card, it is possible to use the telephone card for a long time.
