Abstract

A telephone card includes a remaining call number recording area for recording a number of remaining calls which can be made using the card, and a telephone number storage area for storing a telephone number of a party to be called using the card. The card is inserted into a telephone set to automatically call a telephone set corresponding to the telephone number stored in the telephone number storage area. A telephone set capable of using this telephone card includes a reader for reading information stored on the card, a dialing unit for extracting telephone number information, which is indicative of a telephone number of a party to be called, contained in the read information, and for producing a telephone number signal corresponding to the extracted telephone number and transmitting the telephone number signal on a connecting line, a counter for counting a number of calls made using the card, and a writing unit for subtracting the counted number of calls from a remaining number of calls read in from the card at the end of a call, and for writing the result in the remaining call number storage area of the card. By inserting the card in the telephone set, the party whose phone number is recorded on the card is called automatically.

Claims

1. A telephone card comprising:

a card, said card having information storage means located on said card,

said information storage means including a remaining call number recording area for recording a number of remaining calls which can be made using the card; and

said information storage means further including a telephone number storage area for storing a telephone number of a party to be called;

said telephone number being stored on said card in machine readable form in said telephone number storage area such that when the card is inserted into a sending telephone device in one direction said telephone number may be read by said telephone device into which said card is inserted to automatically call a receiving telephone device corresponding to the telephone number stored in said telephone number storage area, and

said card also carrying predetermined machine readable card enable means for enabling a call to be placed from said sending telephone device after said card is inserted therein, said machine readable card enable means including a predetermined enable mark which may be detected as an enable mark for either enabling a call to be placed automatically or manually after said card has been inserted into said sending telephone device and read by said sending telephone device.

2. The telephone card according to claim 1, wherein in said remaining call number recording area is located on a strongly magnetic body provided on a surface of the card permitting the number of said remaining calls permitted by said card to be read therefrom as a magnetic record.

3. The telephone card according to claim 1, wherein said telephone number storage area is located on a strongly magnetic body provided on a surface of the card permitting said telephone number for automatic dialing to be stored thereon and read therefrom as a magnetic record.

4. The telephone card according to claim 1, wherein said telephone number storage area visually indicates, on a surface of the card, visually readable symbols corresponding to the stored telephone number.

5. The telephone card according to claim 1, wherein said predetermined enable mark is provided on one edge portion of the card, the direction in which the card is inserted being sensible depending upon whether said mark is read.

6. A telephone card according to claim 1 wherein said predetermined enable mark is located on said card at a position such that dependent upon the presence of said predetermined enable mark and the direction in which the telephone card is inserted said predetermined enable mark may be read for either enabling a call to be placed after a telephone number from said telephone card has been read automatically to a telephone set corresponding to a telephone number read from the card when the card is inserted in said one direction, or enabling a call to be placed to a telephone set specified by manual dialing without automatic dialing being performed, when the card is inserted in a direction other than said one direction.

7. A telephone card according to claim 1 wherein said card enable means permits manual dialing in the event that no read telephone number is detected upon reading of said telephone number storage area by said telephone device.

8. A telephone card-operated telephone set comprising reading means for reading information stored on a telephone card;

dialing means for extracting telephone number information, which is indicative of a telephone number of a party to be called, contained in the read information, and for producing a telephone number signal corresponding to the extracted telephone number and transmitting the telephone number signal on a connecting line;

counting means for counting a number of calls made using the telephone card; and

writing means for subtracting the counted number of calls from a remaining number of calls read in from the telephone card at the end of a call, and for writing the result in a remaining call number storage area of the telephone card, and wherein

a direction in which the telephone card is inserted is sensed based upon whether a predetermined mark provided on one edge portion of the telephone cars has been read, a call being placed automatically to a telephone set corresponding to a read telephone number when the card is inserted in one direction, a call being placed to a telephone set specified by manual dialing without automatic dialing being performed, when the card is inserted in a direction other than said one direction.

9. The telephone set according to claim 8, wherein said reading means reads stored information from said card which has been magnetically recorded on a strongly magnetic body provided on a surface of the said telephone card.

10. The telephone set according to claim 8, wherein said reading means reads from said card at least one visible symbol provided on a surface of the said telephone card.

11. The telephone set according to claim 8, wherein a direction in which the telephone card is inserted is sensed based upon whether a predetermined mark provided on one edge portion of the telephone card has been read, a call being placed automatically to a telephone set corresponding to a read telephone number when the card is inserted in one direction, a call being placed to a telephone set specified by manual dialing, without automatic dialing being performed, when the card is inserted in a direction other than said one direction.

12. A telephone card comprising:

a card, said card having information storage means located on said card for storing a telephone number dial code,

said telephone number dial code being stored on said card in machine readable form in a telephone number storage area such that when the card is inserted into a telephone device said telephone number dial code may be read by said telephone device into which said card is inserted for initiating a call automatically to another telephone coupled device, and

said card also carrying predetermined machine readable and enable means for enabling a call to be placed from a telephone device after said card is inserted therein, said machine readable card enable means including a machine readable predetermined enable means which may be detected for either enabling automatic entry of a telephone number dial code of said stored telephone number into the telephone system or manual dialing entry of numbers by a manual dial code being manually entered after said card has been inserted into said telephone device and read by said telephone device;

wherein said predetermined enable means is located on said card at a position such that dependent upon the presence of said predetermined enable means and the direction in which the telephone card is inserted said predetermined enable means may be read for either enabling a call to be placed after a telephone number from said telephone card has been read to automatically connect through the telephone system a call to a telephone set corresponding to a read telephone number when the card is inserted in said one direction, or enabling a call to be placed to a telephone set specified by manual dialing without automatic dialing being performed, when the card is inserted in a direction other than said one direction.
