Abstract

PURPOSE:To prevent an unfair use by storing a telephone number and a code to identify the telephone number to a card and further, setting a password to read these card data. CONSTITUTION:A card to store an optional telephone number, a code to identify the telephone number and the password of these card data is inserted into a telephone set and the password is inputted. When the inputted password is coincident to the password stored into a card, the telephone set receives a code to identify an individual telephone number, for example, the input of the name, etc., of a telephone destination. The telephone number is read from the card by the inputted code and the telephone number is automatically dialed by the telephone set. For an automatic dialing function, since the input of the password and the input of the code come to be conditions, there is no danger that the telephone number is unfairly transmitted by the other person who picks up the card.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention This invention relates to a card telephone system having a card storing a telephone number.

(b) Summary of the Invention The card telephone system according to the present invention stores a telephone number and a code for identifying the telephone number in a card, and further sets a password for reading out these card data.

This allows users to make calls using their cards even if they do not remember their phone number, and also prevents anyone from reading their phone number by setting a password. .

(C) Prior Art and Its Disadvantages Conventional telephones used dials and numeric keys to input the telephone number of the other party to make a call. In recent years, telephones equipped with speed dial devices have been developed, and it has become possible to automatically dial a telephone number by inputting a code shorter than the telephone number. Further, a telephone system has been proposed in which a telephone number is stored in a card and the telephone number can be automatically dialed by inserting the card into a telephone set.

However, the abbreviated dialing of the abbreviated dial telephone is effective only for that telephone and cannot be used with other telephones. Furthermore, in a telephone system that includes a card storing a telephone number, the telephone number is dialed simply by inserting the card, so if the card is lost, for example, there is a risk of unauthorized use.

(d) Purpose of the Invention In view of the above-mentioned drawbacks, it is an object of the present invention to provide a card telephone system that can automatically call a telephone number when a card is inserted and a specific code is input.

(e1 Structure of the Invention This invention provides a card that stores an arbitrary telephone number, a code for identifying this telephone number, and a password for these card data, a card league that accepts the card, and a card league that accepts the card when the card is inserted into the card league. password input means for accepting the input of the password; means for accepting the input of a code for identifying a telephone number when the input password matches a password stored on the card; and a telephone number corresponding to the input code. A telephone set having means for dialing;

ff1 Effect In the card telephone system according to the present invention, when a user wants to make a call, he or she inserts the card into the telephone and inputs a password.

When the input password matches the password stored in the card, the telephone accepts the input of a code for identifying an individual telephone number (the name or appellation of the telephone destination may be used as the code). A telephone number is read from the card according to the entered code, and the telephone number is automatically dialed by the telephone.

(g) Effects of the Invention According to the present invention, a user does not have to memorize each telephone number and can dial the telephone number by inserting a card. Furthermore, since this automatic dialing function requires the entry of a password and a code, there is no risk that someone who has found this card will make unauthorized calls to the telephone number.

As described above, if the code is set to the name or name of the person to be called, there is no fear that the user will forget the code.

As a result, it is possible to realize a card telephone system in which outgoing calls are easy and confidentiality is sufficiently maintained.

(hl Embodiment) Fig. 1 is an external view of a card public telephone used in a card telephone system which is an embodiment of the present invention. A fuel consumption indicator 3 for displaying the remaining energy based on the amount of cash or inserted card, a card insertion slot 4 for accepting an IC card, and a display 5.1 for displaying the input telephone number, etc.

FIG. 2 is a block diagram of the card public telephone m1 and the IC card 30 inserted into the card public telephone 1. As shown in FIG. The CPU 20, which is a control device, includes a ROM 21 that stores programs, etc., a RAM 22 that stores buffers for inserted IC cards, etc., and an NCU 23 that sends dial pulses and the like to public telephone lines. An amplifier 24 that amplifies the audio signal sent to and received from the handset 11, an IC card reader 25 that communicates with the IC card inserted into the IC card insertion slot 4, and an IC card reader 25 that communicates with the IC card inserted into the IC card insertion slot 4; a coin processing machine 26 for processing coins, an input processing unit 27 that receives input from the numeric keypad 8 and the keyboard 9, the handling display 2, the frequency display 3, and the display 5.
a display section 28 that controls the display; and a hook switch 29 that is turned on and off by the vertical movement of the hook 10.
is connected. Further, the 1C card 30 connected to the IC card reader 25 includes a CPU 31 and a CPU 3.
A terminal 32 for communicating data and the like with the memory 33 and the IC card reader 25 connected to the terminal 1 is connected.

FIG. 3 is a partial configuration diagram of the memory 33 of the IC card 30. The memory 33 is composed of a ROM for storing fixed data such as programs and an EEFROM for storing data that can be rewritten as necessary. This partial configuration diagram is a partial configuration diagram of an EEPROM. Area Ml (hereinafter 1 area Mi is referred to as “Mi”)
The amount paid in advance for the use of the telephone is stored as a frequency. This number is decremented each time you use the phone. A password for using this card is stored in area M2. In order to make a call at the card public telephone using this card, the user must enter this password after inserting the card. If the entered password does not match the password stored in this area, not only the above-mentioned amount (frequency) but also automatic dialing of a telephone number, which will be described later, cannot be used. Area M3 stores a predetermined telephone number and a name that is a code for identifying the telephone number. If this name is entered using the keyboard 9, a telephone number will be automatically dialed. N pairs of names and telephone numbers are stored.

FIG. 4 is a flowchart showing the operation of the card public telephone 1. As shown in FIG. First, step nl (hereinafter “step ni”)
" is called "ni".), the handset 11 is picked up (
(the hook is turned off), and the IC card 30 is inserted into the IC card reader 25 from the IC card insertion slot 4 (n2).

The input of the password is accepted at n3, and the input password is displayed on the display 5 (n4). When the password input is completed, it is determined whether the password matches the password stored in the IC card (n5).

- If the call is made, the process advances to n6 to accept the input of the name of the person to be called. If the passwords do not match, a message to that effect is displayed (n13), and if the password is to be re-entered, the process returns to n3 based on the judgment in n14, and if the password is not to be re-entered, the process goes to nil.

If the name of the person to be called is entered in n6, the name is displayed on the display 5 (n7), and a search is made to see if the phone number identified by that name is stored in the IC card (n7).
