Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electronic telephone directory that stores a large number of telephone numbers in an electronic memory such as a semiconductor memory.

Traditionally, a telephone directory is a record used to write the name and telephone number of an acquaintance in a memo pad, and when making a call, refer to it and call the other party's telephone by dialing or pressing the button on the telephone. An electronic telephone directory uses electronic memory as a medium.

When using these conventional telephone directories, a person must look at the telephone number displayed in the telephone directory, memorize it in their head, and then turn the dial with their fingertips. The problem was that the wrong number could be dialed in some cases.

Additionally, if the telephone is equipped with an auto-dial or speed-dial function, this error will not occur, but if the auto-dial or speed-dial number is set to a different telephone number depending on the phone. Therefore, it is not easy to call an acquaintance using auto dial or speed dial from a telephone other than one's own telephone, as the number must be re-registered. As a result, I ended up having to carry the telephone directory with me.

The present invention provides a portable electronic telephone directory that stores a large number of telephone numbers in an electronic memory with an acoustic coupler that acoustically couples a selection signal to a telephone transmitter, and an auto-dial function or speed dial function using a PB signal. and by acoustically coupling the acoustic coupler to a telephone handset and pressing any auto-dial button or speed-dial button, the destination phone number stored in the electronic memory (e.g., auto-dial) corresponds to the button. Number 3 is 045-123-45
A selection signal corresponding to 67) is sent from the acoustic coupler to the telephone line via the telephone transmitter, and the telephone exchange is operated to selectively connect the other party's telephone line and call the other party's telephone.

As described above, the portable electronic telephone directory according to the present invention makes it possible to call a frequently called telephone from any telephone by auto-dial or speed dial, thereby solving the above-mentioned drawbacks of the conventional telephone.

The present invention will be described below with reference to embodiments shown in the drawings.

FIG. 1 shows an embodiment of a calling method for a portable electronic telephone directory according to the present invention, in which a portable electronic telephone directory (1) is acoustically coupled to a transmitter (3) of a telephone (2) and a portable electronic telephone directory (1) is acoustically coupled to a transmitter (3) of a telephone (2). The selection signal sent from the electronic telephone directory (1) is sent to the telephone exchange (5) via the telephone line (4), selects the other party's telephone line (6), and calls the other party's telephone (7).

To explain more specifically with reference to FIG. 2, the portable electronic telephone directory (1) can be operated by pressing the auto-dial button (8) corresponding to the telephone number (7) of the person you wish to call. 9) instructs the CPU (10) to read out the telephone number stored at the address specified by the CPU (10) from among the one or more calling telephone numbers stored in the semiconductor memory (11), and outputs the PB signal. The signal from the transmitter (12) is sent to the auto-dial circuit (9) to determine the combination of multi-frequency signals and the order in which signals are sent corresponding to the called party's telephone number to form a selection signal for selecting the called party's telephone (7). The selection signal is transmitted from the telephone set (2) to the telephone line (4) through the transmitter (3) that is fitted and acoustically coupled to the telephone exchanger (5), and is read by the PB signal receiving circuit of the telephone exchange (5) and transmitted to the other party's telephone line. (6) is selectively connected and the other party's telephone (7) is called.

The above embodiment deals with making local or international calls from within the same city, but the feature of the present invention is that you can call your acquaintances wherever you go. A toll switch (14) shown in FIG. 2 has additional functions. Toll switch (1)
4) When making a call from outside the city to an acquaintance who normally makes a local call, by switching the switch (14), the phone number with the area code added can be retrieved from the portable electronic telephone directory (1). It is sent as a selection signal, and when registering a calling phone number in the memory (11), the mechanism sends two phone numbers for one phone: a phone number with an area code and a phone number with a local code. By memorizing a different address and operating the toll switch (14), even if you press the same auto-dial button (8), you can choose between a phone number with an area code or a phone number with a local code, and receive the correct selection signal. It is used to send out the following information. It is also easy to provide a display (15) to confirm the telephone number being sent. Note that writing phone numbers, etc. to the electronic memory (11) can be done by using the mode changeover switch (16) to convert the auto dial button (8) into a phone number input button, or by using an external keyboard using optical transfer method or magnetic force transfer method. It is also easy to do this by inputting

As described above, according to the present invention, a portable electronic telephone directory (1) that stores a large number of telephone numbers in an electronic memory (11),
Acoustic coupler (13), auto dial circuit (9) auto dial button (8) PB signal transmitter (12) CP
The acoustic coupler (13) is equipped with an auto dial function or speed dial function consisting of a telephone (2), etc.
) by pressing the auto-dial button (8), the acoustic coupler transmits a selection signal corresponding to the telephone number of the other party stored in the electronic memory (11) corresponding to the button. from the telephone (2) through the transmitter (3) to the telephone line (4), activates the telephone exchange (5), selects and connects the other party's telephone line (6), and connects the other party's telephone line (7).
This eliminates the need for people to memorize phone numbers with many digits in their heads and dial them, thereby preventing them from dialing the wrong number.Since this phonebook is portable, it is possible to call from any phone from any phone. It also has the effect of being able to call one's acquaintances by auto dialing or speed dialing.
