Abstract

PURPOSE:To release a telephone set user from the trouble of radial and the memory of a subscriber telephone number by writing dial information dialed by a subscriber into magnetic card and reading the dial information by a telephone set. CONSTITUTION:When a magnetic card 7 is inputted from a card unit part 4, first, a control part 5 discriminates whether the card is a calling card in which frequency data are written or a subscriber card in which frequency data are written and a subscriber telephone number can be written. When it is discriminated that the card is a subscriber card and the button (*) of a telephone set 1 is pushed down, the subscriber telephone number stored in the subscriber card is extracted and this number is sent automatically to an exchange 6 through a calling part 2. On the other hand, when the button (*) is not pushed down, the telephone number inputted by dial operation is sent to the exchange 6 through the calling part 2 and the telephone number is stored in the subscriber card.

Description

Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a magnetic card type public telephone that allows calls by using an inserted magnetic card, and in particular, the present invention relates to a magnetic card type public telephone that allows telephone calls by using an inserted magnetic card. ) is written on a magnetic card and automatically dials by reading the written dial information.

[Prior Art] Conventionally, this type of magnetic card-type public telephone has stored information on the charges at which calls can be made, that is, data on the number of calls that can be made, on the magnetic card. , or allows you to make phone calls with peace of mind even when you don't have a lot of change.

When making a call using a magnetic card, follow the steps below.

First, remove the handset and insert the magnetic card into the slot in the top center of the phone. Next, when you hear the dial tone, dial the other party's phone number and make the call.

[Problems to be Solved] However, the above-described conventional magnetic card type public telephone has the following problems.

The above-mentioned magnetic card type public telephones use magnetic cards in place of coins to make calls. Therefore, like a regular public telephone, the telephone number of the other party was dialed using the telephone itself, which was like a regular subscriber telephone. As a result, if the person on the other end of the call is busy or absent, and the user wants to make a call to the same person after a while, the person's phone number must be dialed again, which prevents the user from making long-distance calls. etc., it was not convenient as it sometimes resulted in incorrect dialing.

[Means for Solving Problems] A magnetic card type public telephone according to the present invention is a magnetic card type public telephone machine that allows calls by using an inserted magnetic card. a discrimination means for discriminating whether the card is a calling card that stores a call card or a subscriber card that stores the frequency data and is capable of storing dialing information of the subscriber; and a reading means for reading the dial information stored in the subscriber card when the subscriber card is determined to be a subscriber card by the discriminating means. It is composed of

[Example] Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of a magnetic card type public telephone according to an embodiment of the present invention. In the figure, a magnetic card type public telephone 1 includes a telephone part 2 including a handset, a dial part, a dial pulse sending part, etc., a middle plate part 3 for sorting and storing inserted coins, and a magnetic card 7 to be inserted.
The phone is comprised of a card unit section 4 that performs feeding and reading operations, and a control section 5 that controls each section of the telephone. Also,
A talking section 2 of this public telephone 1 is connected to an exchange 6 of the central office.

Next, the operation of this embodiment will be explained with reference to FIGS. 2 and 3.

FIG. 2 is a diagram showing a subscriber card according to this embodiment, and FIG. 3 is a diagram showing a flowchart showing the operation of this embodiment.

First, when the magnetic card 7 is inserted from the card unit section 4, the magnetic card 7 is detected by the card unit section 4 (step 101).

Next, the card unit section 4 issues a command to the control section 5 to detect the magnetic card. Then, the control unit 5 determines whether the inserted magnetic card 7 is a calling card on which the frequency data is written or a subscriber card on which the frequency data is written and on which the subscriber telephone number can be written (step 102). When it is determined that the magnetic card 7 is a subscriber card, the control unit 5 changes the "*" mark of the magnetic card public telephone 1.
Step 103) Determine whether the button has been pressed or not.
, the subscriber telephone number stored in the subscriber card is extracted (step 104). FIG. 2 shows a state in which the subscriber telephone number "r0123456789" is stored in the subscriber card.

Next, the control unit 5 monitors the coin insertion (step 105).
, When the input is received, the subscriber's telephone number extracted in step 104 is automatically sent to the exchange 6 via the dial pulse sending part of the communication part 2 (step 106). Calls between subscribers can be made by simply pressing the button.

Further, if "*" is not pressed in step 103, it becomes possible to make a call after dialing in the same way as when making a call using coins or using a calling card (steps 107 and 108).

In this case, the control section 5 supplies the subscriber's telephone number, that is, dial information, sent to the exchange 6 via the dial pulse sending section of the communication section 2 to the card unit section 4, and adds the dial information by the card unit section 4. person card.

For example, subscriber phone number r01234 as shown in Figure 2.
Write 56789J. As a result, the next time you make a call, you can simply press "*" as described above.

[Effects of the Invention] As explained in detail above, according to the present invention, in a magnetic card type public telephone, dial information dialed by a subscriber is written on a magnetic card, and the written dial information on the magnetic card is read. As a result, users of public telephones are freed from the trouble of re-dialing and from having to memorize subscriber telephone numbers, which has a great effect on the users and has an extremely large practical effect. Furthermore, it is also possible to perform general dialing, which is a conventional dialing procedure, using a magnetic card on which a subscriber's telephone number is written, further increasing the effectiveness of the system.
