Abstract

PURPOSE:To improve convenience by recording dial data on a telephone card to attain automatic dialing in use afterward at the 1st use of the telephone card. CONSTITUTION:When the telephone card is inserted to a card read 4, the data on the telephone card is read and stored in a memory 2. When the data relating to automatic dialing destination does not exist in the card data, it means the 1st use and a display representing manual dialing is given on a display device. When the automatic dial destination data exists in the card data, a dial signal of a telephone number represented by the data is sent from a telephone set circuit 3. When the line is connected to the talking destination, since the line voltage polarity is inverted, it is detected and talking is attained.

Description

[Detailed Description of the Invention] Summary of the Invention In a card telephone that permits calls within the residual value of a telephone card on which a value is recorded, dialing data is recorded on the telephone card at the first use of the telephone card. death,
The feature is that automatic dialing is possible during subsequent use.

[Background of the Invention] The present invention relates to a card telephone that permits telephone calls within the residual value of a telephone card whose value is recorded. Here, the term "telephone" is not limited to one that transmits voice, but also includes terminals for transmitting data and telephone lines connected by two communication lines. That is, the above-mentioned telephone call is a concept that includes not only the transmission of voice signals but also the transmission of data.

Telephones that can make calls using a telephone card are becoming more popular, but instead of paying for two calls in cash for each call, the value data of the telephone card, which has been purchased in advance and has added value, is reduced. You pay the call charges. Here, the telephone card is only used as a substitute for monetary value.

Telephone cards have a magnetic recording surface, and magnetic recording is characterized by the ability to accurately store a large amount of information. Therefore, it is desired to utilize the characteristics of magnetic recording to provide telephone cards with more functions.

[Object of the Invention] An object of the present invention is to provide a card telephone with more practical functions by taking advantage of the above characteristics of the S-talk card.

[Configuration and Effects of the Invention] The present invention provides a card telephone that is equipped with a card reader for reading card data of a telephone card in which two values are recorded, and that allows telephone calls within the range of the values in the card data. means for determining whether or not the telephone card is used for the first time; means for reading and storing dial-data in the case of the first use; dialing--means for writing data onto the telephone card and, in case of use other than the first time, automatic dialing means for issuing a dialing signal based on the dialing data read from the telephone card. It is characterized by

Whether or not the telephone card is being used for the first time can be determined based on the data read from the telephone card. Since dialing data has already been written to the telephone card when it is used for the second time or later, if there is no dial dispute data in the card data, it is the first use, and if there is dialing data, it is the first use. This means that it will be used from the second time onwards. Of course, the user may be required to input a key to indicate that this is the first use.

Reading of dial data can be performed by decoding (including detection) dial signals (including push and button signals) sent from the telephone set. In the case of a button/dial type, this can also be done by starting up the contact signal of the button/button.

Automatic dialing can be done by creating a pseudo dial signal according to the dialing data (dial number), or in the case of a button button type, by connecting a switch in parallel with the button button, and connecting these switches electrically. This could be done in a variety of other ways, such as by operating the

The writing means may be configured to write the dial data to the telephone card after a writing confirmation input is received. If there is no write confirmation input, the dial data will not be written to the phone card.

If it is determined whether it is the first use based on the card data, it will always be the first use unless dial data is written.

By configuring the automatic dialing means to send a dialing signal after an automatic dialing selection input is made, it becomes possible to manually dial any dialed number even in the second and subsequent uses.

As described above, in this invention, when the telephone card is used for the second time or later, a dialing signal is automatically sent out based on the dialing data already recorded on the telephone card, thereby eliminating the need for manual dialing. Additionally, even if you forget your phone number, you can still make calls as long as you have your phone card, which is convenient. Since the dial data (telephone number) manually dialed during the first use is recorded on the telephone card by the telephone, the user does not need to have a dial data recording device or the like.

When allowing the use of two or more telephone cards in one call, that is, when the value of the first telephone card becomes zero, the insertion of a second telephone card with some value is accepted.1 For card telephones that allow calls to continue, after one call ends, the first card is added to the second phone card.
Preferably, the dialing data recorded on the second telephone card is recorded automatically or selectively based on key input.

[Description of Embodiments] FIG. 1 shows an example of the electrical configuration of a card telephone.

This card phone is controlled by a CPUI, preferably a microprocessor. The CPU has a memory 2 that stores the program and also stores necessary data.
is provided. The telephone circuit 3 has, in addition to the normal calling functions, the functions of selecting a party and transmitting/receiving a calling signal, the function of detecting dial data (telephone number, automatic dial destination) and the function of automatic dialing. Attached to this circuit 3 is a card reader 4 which reads the data of the telephone card and writes the necessary data to the telephone card. Call signals and the like are transmitted and received via the modem 5.

FIG. 2 shows part of the contents of the memory 2.

This memory 2 stores card data for reading and writing from telephone cards.

As is clear from this diagram, the phone card has

Card issue number, including that it is a telephone card.

(Card No.), residual value (remaining card number), automatic dialing destination, etc. are recorded or have been recorded.

FIG. 3 shows the processing procedure by the above-mentioned card telephone, particularly by the CPUI.

When a telephone card is inserted into the card reader 4, this is detected (step 11) and the data of the telephone card is read by the card Φ reader 4 and recorded in the memory 2 (step 12).

Based on the read card data, checks are made to see if it is a telephone card, whether the residual value is reasonable, etc., and if it passes these checks and is determined to be valid (step 13).

Subsequently, it is determined whether this is the first use (step 14).

If there is no data regarding the automatic dial destination in the card data, this is the first use, and in this case, a message to manually dial is displayed on the display (illustrated path) (step 15). Since the user dials manually, a dial signal is sent out, and dial data (dialed number) is detected and stored in the memory 2 (step 1B).

If there is automatic dial destination data in the card data, the dialing signal for the telephone number indicated by this data is sent to the telephone circuit 3.
(step 17).

When the line is connected to the other party, the polarity of the line voltage is reversed, and this is detected (step 18), allowing one phone call to be made (step 19).

Call time 9 Billing pulses are sent from the station according to call distance, etc. (Step 20) The residual value (remaining number of points) in the card data in memory 2 is subtracted by a predetermined value every 2 billing pulses. (Step 21).

If the residual value becomes zero, the line may be disconnected by going on-hook.

When the calling or called party goes on-hook, the call ends (step 22), and based on this detection, the card data in the memory 2 is written to the telephone card by the card reader 4. Due to this.

The residual value of the telephone card is updated and the automatic dial destination data is recorded on the telephone card (step 23).
.

After this, the telephone card is returned (step 24).

If it is extracted by the user (step 25),
Processing ends.

If the card is determined to be invalid in step 13, that fact is displayed on the display (step 26), and the card is returned.

A key for selecting automatic dialing or two-manual dialing may be provided, and the process may proceed to step 17, automatic dialing, only when automatic dialing is selected.

Alternatively, a key for confirming automatic dial destination writing may be provided, and the automatic dial destination data may be written to the telephone card in step 23 only when this confirmation is received. Needless to say, the residual value of the telephone card is updated even if the automatic dial destination is not written.
