Abstract

PURPOSE:To eliminate the need for dialing a dial number for each occasion and to prevent mis-dialing by loading a telephone card to a public telephone set and storing a telephone number corresponding to an abbreviated dial code through key operation. CONSTITUTION:A new telephone card 1 is loaded to a card loading/ejecting port 7 of a public telephone set 4 and, for example, a telephone number of '0123-456-789-0123' is dialed to enter talking. In this case, for example, a key entry of input section 6 as '*1#' is operated. Through the key entry, '*1' is stored in an abbreviated code area of the telephone card 1 and '0123-456-789-0123' is stored in a telephone number area. When the same number is used for talking, after the loading of the telephone card 1, a call unit, an abbreviation code and a telephone number are displayed on a display section 8 by having only to depress only the abbreviation code '*1'. After the confirmation of the displayed number, when a key such as '#' is depressed, the object number '0123-456-789-0123' is automatically dialed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a telephone card that can record a speed dial code, and a public telephone that can perform automatic dialing using this telephone card.

``Prior art'' When a conventional telephone card is inserted into a public telephone, the stored telephone card identification information is determined, the number of charges is displayed, and after use, the remaining number of charges is stored. Ta.

``Problem to be solved by the invention'' Traditionally, domestic telephone numbers were assigned 10 digits, including the city code. However, in recent years, the number of Type 1 communication network services has increased, and when using these services, it is necessary to operate a 14-digit dial number.

However, because public telephones do not have contracts for speed dialing, dialing all numbers has to be done, which is inconvenient, as it takes too much time and is prone to errors.

The object of the present invention is to provide a telephone cart that allows all numbers to be dialed simply by operating an abbreviated code stored in the telephone cart.

``Means for Solving the Problems'' The present invention provides a public telephone that can be operated using a telephone card that records charge frequency, the public telephone having a card interface section that can record and call data such as telephone numbers on the telephone card. , a memory capable of recording and reading data, an input section for dialing a code retrieved from the memory by operating an abbreviated key, and a display section for displaying the dialed number.

"Operation" A telephone card is inserted into a public telephone in advance, and the speed dial code and corresponding telephone number are recorded by key operation.

Next, when you insert this telephone card into a public telephone,
The power of the telephone card and pre-recorded speed dial data are temporarily stored in the memory. When speed dialing is performed, the corresponding telephone number is dialed and displayed on the display. It is then connected to the other party via a dialer and telephone line.

Alternatively, a method may be adopted in which the abbreviated code and telephone number are automatically recorded on the telephone card each time a call is made.

When the user hangs up the phone after speaking, the public phone's memory is cleared and the phone waits for the next phone card to be inserted. In addition to the above-mentioned functions, the public telephone is also provided with a function that allows a speed dial code once recorded on a telephone card to be inserted into the public telephone and copied to another new telephone card.

"Example" Hereinafter, one embodiment of the present invention will be described based on the drawings.

In Figure 1, (1) is a telephone card, and this telephone card (1) stores information such as charges, frequency, telephone card identification, etc. as before, and shortened telephone code (2)... It is equipped with a memory in which code (2), phone number (3), and so on are stored.

In Figure 2, the public telephone (4) has a handset (5).
), input section (6) such as push button switch, card slot (
7) and a display section (8). This display section (8) includes a residual power display window (9) and a shortened code display window (1) that displays the shortened code (2).
0), and a telephone number display window (11) that displays the telephone number (3).

As shown in FIG. 3, the internal control circuit of the public telephone (4) includes a card interface (12) for coupling with the telephone card (1), a display section (8) for displaying the degree, number, etc., and a speed dial. An input section (6) for performing operations, normal dial operations, number writing operations, copy operations to other cards, and other inputs, an input section interface (13) for this input section (6), and programs for various controls. R
OM (14), data RAM (15) for storing frequency abbreviation codes, telephone numbers, etc., a dialer (17) connected to the telephone line (16), and a CPU (18) that controls these.
).

Next, the present invention will be explained in detail.

Insert a new telephone card (1) into the card slot (7) of the public telephone (4). Then, the power is displayed in the power display window (9) of the display section (8).

Next, for example, r0123-456-789-0123
” and make a call. At this time, for example, r*1
Operate #J and the keys on the input section (6). With this operation, "*1" is added to the short code area of the telephone card (1), and r0123-456-789-01 is added to the phone number area.
234 is recorded.

In this state, end the call, hang up the handset (5), and remove the telephone card (1) from the card slot (7).

The next time you make a call using the same number, please include your telephone card (1).
), just press the short code “*1”.
The display unit (8) displays the frequency, abbreviation code, and telephone number.

After confirming this displayed number, for example, if you press "#",
Automatically dial the target r1234-1234-56-7890J.

When the frequency of telephone card (1) reaches O, or even if it does not reach O, the short code (
When trying to copy 2) and phone number (3),
- Data from your old telephone card (1) can be transferred to a public telephone (
4) is temporarily stored in the internal RAM (15), and then inserted into another telephone card (1) and copied. After copying is completed, RAM (15) is erased.

"Effects of the Invention" Since the present invention is configured as described above, there is no need to input a dial number of up to 14 digits each time, and moreover, it is possible to eliminate dialing errors.
