SOLUTION: When a call signal detection section 14 of the telephone set 1 detects a call signal sent via a line 100, a control section 10 makes incoming call processing and sends a message to urge a caller opposite party to enter a password based on data stored in a message memory 24. When a password detection section 26 detects the password entered by the caller opposite party, a password collation section 30 reads a password set in advance and stored in a password memory 28, collates the password stored in the password memory 28 with the received password, a call tone output section 18 outputs a call tone when the received password is correct and the control section 10 sends an instruction to a line connection section 12 to interrupt the connected line 100 when the password is not correct.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone capable of communicating with an unspecified number of subscribers.

[0002]

2. Description of the Related Art Conventionally, a telephone connected to a public telephone network receives a call such as a prank call, a wrong call, or a forcible sales. There is no. For example, if you try to accept a call only from a specific party, the phone number will be shown only to the specific party, the phone number of the other party will be displayed when you receive a call, and the phone number of the specific party will be displayed And then picking up the handset, picking up the handset, checking the other party, and continuing the call only for the specific party.

[0003] However, when a telephone number is given to a specific party (in the case of), mischievous calls and forcible sales calls can be reduced, but incorrect calls cannot be effectively eliminated. For example, when a telephone number of a restaurant that is frequently called has a telephone number that is one digit different from the telephone number of a restaurant, many wrong telephone calls are made regardless of who knows the own telephone number.

In the case of confirming the other party by displaying the telephone number of the other party (in the case of), the confirmation work becomes complicated when the number of acquaintances or the like who notified the telephone number increases. In addition, when an acquaintance or the like who is the caller calls from a public telephone or a place other than home, the telephone number of the acquaintance or the like's home is not displayed. Not be able to talk.

[0005] Further, once the telephone receiver is picked up and the other party is confirmed (in the case of), mischievous telephone calls and the like cannot be prevented at all, and no measures are taken. As described above, conventionally, the user himself does not have to perform complicated operations,
It was inconvenient because it was not possible to select and answer a specific call partner.

[0006] The present invention has been made in view of the above points, and an object of the present invention is to provide a telephone capable of answering a specific call partner.

[0007]

In order to solve the above-mentioned problems, the telephone of the present invention sends a password transmission request to the other party after receiving a call, and responds to the second request sent from the other party. A ringing tone is output when the password matches the first password set in advance, and the line is disconnected without outputting a ringing tone when the password does not match. Therefore, the user of this telephone can select a specific call partner simply by notifying the set password to the call partner in advance, and can answer a call from the specific call partner. . In particular, when a caller who does not know a preset password calls, the line is disconnected without outputting a ringing tone, so that the user is not bothered each time.

It is preferable that the above-mentioned second password sent from the other party be detected by voice recognition processing. Since the other party only needs to speak a predetermined password, the operation can be simplified. Further, since it is not necessary to compose a password using a combination of numeric keys and the like provided on the telephone, the degree of freedom in password setting is increased.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION A telephone according to an embodiment of the present invention sends a message prompting for a password when a call is received, and makes a call based on the password sent in response to the message. It is unique in selecting opponents. Hereinafter, a telephone according to an embodiment to which the present invention is applied will be described with reference to the drawings.

FIG. 1 is a diagram showing the configuration of the telephone according to the present embodiment. The telephone 1 shown in FIG. 1 includes a control unit 10, a line connection unit 12, a call signal detection unit 14, a handset 16, a ring sound output unit 18, a recording / playback unit 20, an operation unit 22, a message memory 24, and a password detection unit. 26, a password memory 28, and a password collating unit 30.

The control unit 10 controls the entire telephone 1 so that, in addition to a normal call function, an answering machine function for recording a call content of a call partner after outputting a predetermined message when the user is absent, and a specific call function. A call partner selection function of selecting a call partner and outputting a ring tone is realized. Line connection unit 12
Is for establishing a physical interface with the public telephone line 100, and performs network control and the like necessary for line connection under the control of the control unit 10. Call signal detector 1
4 detects ringing (ringing signal) of 16 Hz transmitted from a public telephone network (not shown) via the public telephone line 100. The transmitter / receiver 16 integrates a transmitter and a receiver, and converts a user's voice into an electric signal and also converts an audible frequency electric signal transmitted via the public telephone line 100 into a voice.

The ringing tone output unit 18 is connected to a public telephone line 100.
When a calling signal is transmitted via the control unit 10, a predetermined ringing sound is output in response to an instruction from the control unit 10. The recording / reproducing unit 20 records the answering machine message uttered by the other party during the operation of the answering machine function, and reproduces the recorded answering machine message in response to a subsequent instruction from the user. The operation unit 22 is for inputting various instructions by the user, and includes numeric keys “0” to “9”, “#” key, and “*” key necessary for calling operation from the telephone 1. "Answer" key to set and release the answering machine function and "Registration" to register password
It is provided with a "call destination selection" key for setting and releasing a call partner selection function by collating keys and passwords. The message memory 24 is for storing a predetermined fixed message. The fixed message includes a message prepared for the answering machine function and a predetermined message for prompting the called party to enter a password when the call party selection function is set.

The password detecting unit 26 is connected to the public telephone line 1
The password sent from the called party via 00 is detected. For example, assuming that the called party presses the numeric keypad of his / her own telephone to transmit a password of a predetermined number of digits, the password detection unit 26 outputs a tone signal or dial pulse signal transmitted corresponding to each digit of the password. , The password corresponding to these signals is extracted. The password memory 28 stores a password preset by the user. The user can input the password by pressing the “register” key after arbitrarily selecting and pressing the numeric keypad of the operation unit 22 for the number of digits of the password. The password is sent from the control unit 10 to the password memory 28 and stored therein. Password collation unit 30
Compares the password detected by the password detection unit 26 with the password stored in the password memory 28, and sends the comparison result to the control unit 10.

The control unit 10 and the line connection unit 12 described above
Is a line disconnecting unit, the control unit 10 and the message memory 24 are a message output unit, the ringing tone output unit 18 is a ringing tone output unit, the password detecting unit 26 is a password detecting unit, the password memory 28 is a password storing unit, The password matching units 30 correspond to password matching means, respectively.

The telephone 1 of the present embodiment has such a configuration, and the operation will be described next. FIG. 2 is a flowchart showing an operation procedure of the telephone 1, and shows an operation procedure after a user presses a call destination selection key provided in the operation unit 22 and sets a call partner selection function.
The control unit 10 constantly determines whether or not a call signal transmitted from the telephone network via the public telephone line 100 is detected (step 100). The call signal is detected by the call signal detection unit 14. Then, a predetermined incoming call process is performed, and a rotational connection is made with the telephone of the other party to which the call signal is transmitted (step 101).

Next, the control unit 10 controls the message memory 2
4 is read out, and a message prompting the input of the password is transmitted to the other party of the called party (step 102). For example,
A voice message such as "Please enter your password" is sent to the other party. Thereafter, the control unit 10 determines whether or not the password has been received by the password detection unit 26 (Step 103), and if not, determines whether or not a predetermined time has elapsed (Step 104). Before the elapse of the predetermined time, the process returns to step 103 (password reception determination) and the process is repeated. After a certain period of time has elapsed without a password being sent, the control unit 10 reads out predetermined message data from the message memory 24 and returns a response message such as "I cannot answer this phone". Is transmitted to the called party via the line connection unit 12 (step 10).
5), sending a line disconnection instruction to the line connection unit 12;
The connected line is disconnected (step 10).
6). Thereafter, step 100 (determination of the presence or absence of a call signal)
And the process is repeated.

When the password input by the called party is sent and detected by the password detection unit 26 (when the determination is affirmative in step 103), the control unit 10 then proceeds to the password verification unit 30. To the password comparison unit 32
The received password and the password memory 28
Then, it is determined whether or not the passwords match each other by comparing with the password stored in (step 107). If a negative determination is made in this determination process, that is, if the received password does not match the preset password, the process proceeds to step 105 described above, such as “I cannot answer this phone”. Is transmitted, the connected line is disconnected.

If the received password matches the preset password, an affirmative determination is made in the determination processing of step 107, and then the control unit 10 sends a predetermined Output sound. After the ringing tone is output in this manner, the telephone 1 operates as in the conventional model. For example, when the user picks up the handset 16 while the ringing tone is being output, a conversation between the user and the other party of the destination can be performed. If the "answering" key of the operation unit 22 is depressed when the user goes out and the answering machine function is set, after the ringing tone is output a predetermined number of times, the control unit 10
Transmits a message such as “Please give me your name and business message after the dial tone” to the called party, and records the audio signal sent from the called party in the recording / playback unit 20.

As described above, the telephone 1 according to the present embodiment performs a call receiving operation in response to a call signal, transmits a message prompting the user to enter a password, and waits for the input of a password. If the password is correct, a ringing tone is sounded, and if the password is incorrect, the line is disconnected without a ringing tone.
Therefore, you can only respond to specific parties who know the correct password,
It is possible to completely cut off calls such as wrong calls and aggressive sales.

The present invention is not limited to the above embodiment, and various modifications can be made within the scope of the present invention. For example, in the above-described embodiment, the password input by the called party is transmitted using a tone signal or a dial pulse signal, but the password is directly uttered, and based on the transmitted voice signal. The password may be extracted by performing voice recognition processing. In this case, the password detection unit 2
6 may be constituted by a speech recognition circuit.

Further, in the above-described embodiment, the case where the telephone 1 having the answering machine function is provided with the call party selection function has been described. However, the present invention can be applied to a telephone having no answering machine function.

[0022]

As described above, according to the present invention, a transmission request for a password is sent to the other party after receiving a call, and in response to this, the password sent from the other party matches the preset password. Sometimes, a ringing tone is output, and when they do not match, the line is disconnected, so that it is possible to answer only a call from a specific call partner who has been notified of the password in advance.
