Description

DETAILED DESCRIPTION OF THE INVENTION (A) Field of Industrial Application The present invention relates to a password registration device provided in a telephone device.

(b) Prior art In order to provide modern telephone devices with a function to prevent prank calls or a function to prevent mistaken calls, etc.
It is equipped with a PIN number registration device, and is designed not to generate a ringing tone even if an incoming call is received unless the caller is a specific person who knows the PIN number. For example, the telephone device described in Japanese Patent Application Laid-Open No. 55-11668 is a tamper-proof telephone that first receives a ringing signal from the caller, then closes the telephone line but does not emit a ringing tone. Instead, it sends a message to the caller requesting that they enter their PIN number. In contrast, the PIN sent by the caller is compared with the PIN that has been previously registered in the PIN registration device, and if the PIN sent by the caller is correct, a ringing tone is generated. and call the owner.
In addition, some answering machines have recently been equipped with external remote control functions or message functions, so a password registration device is used to prevent unauthorized persons from operating the telephone from the outside.
53-34685, the users of the remote control function and message function are limited.

(c) Problems to be solved by the invention PIN code registration for registering a PIN number used to perform operations such as limiting the caller or limiting the remote operator on the telephone device as described above. In general, the device uses a push button to store and register DTMF signals corresponding to each digit of a plurality of digits formed by a combination of key buttons to form a password. To register such a PIN, you operate each key button according to the operating procedure, but in this case it is necessary to operate a special key button, and if the registration operation fails, the registration will be restarted from the beginning. There was a problem in that the operation had to be repeated and the operation was troublesome. Furthermore, since the special key button is sometimes used for another purpose, there is a problem in that if the special key button is operated to register a password, and if the password registration operation fails, a function for another purpose will be activated. Therefore, in order to solve this problem, the present invention provides a password registration device for a telephone device that allows the password registration operation to be performed easily and reliably.

An erroneous signal sound emitting circuit notifies that the signal generation circuit has output, and when a DTMF signal corresponding to a number from 0 to 9 is output from the registration signal generation means,
Based on the DTMF signal, it detects that the PIN registration circuit in which a multi-digit PIN is registered, the PIN registration button that puts the PIN registration circuit into the PIN registration state, and the false signal sound emitting circuit emit a sound. and a control circuit for erasing the password registered in the password registration circuit.

(e) Effect The PIN number registration device for the telephone device of the present invention is configured such that # and * other than numbers 0 to 9 are input so as to register only the PIN number that is a combination of numbers 0 to 9 on the push button switch. If so, it is determined that an erroneous operation has been performed, and a sound is emitted to notify the user of the erroneous operation, and the previously registered password is deleted.

Next, the operation of one embodiment of the present invention will be explained using the drawings. First, the operation of registering a password in the password registration device of the telephone device of the present invention will be explained. Both the telephone circuit 9 and the answering machine circuit 6 are opened. When the password registration switch 13 is closed in such a state, the remote control function control circuit 14 activates the registration signal identification circuit 20 and the false signal sound emitting circuit 21. Further, the password registration circuit 16 of the password identification circuit 15 erases the registered contents under the control of the remote control function control circuit 14, and enters an operating state in which storage and registration are possible.
In such a state, when first operating the push button switch 12 to register a password, operating the push button switch 12 with "1", "2", and then pressing "3" is called "*". If a special key is operated by mistake, the DTMF signal corresponding to "1" is first identified by the registered signal identification circuit 20, and since it is a DTMF signal corresponding to the numbers 0 to 9, it corresponds to "1". The DTMF signal is stored and registered in the password registration circuit 16 via the fifth output terminal 20c. DTMF corresponding to the next "2"
The signal is also identified by the registered signal identification circuit 20, and similarly to the DTMF signal corresponding to "1", it is 0 to 1.
"2" because it is a DTMF signal corresponding to the number 9
The DTMF signal corresponding to the DTMF signal is stored and registered in the password registration circuit 16 via the fifth output terminal 20c. The DTMF signal corresponding to the next "*" is also identified by the registration signal identification circuit 20. Corresponds to "*"
The DTMF signal is a DTMF signal corresponding to numbers 0 to 9.
Since it is not a signal, the registered signal identification circuit 20 outputs control signals from the third output terminal 20a and the fourth output terminal 20b, respectively. Said third output terminal 20
The control signal output from a is sent to the error signal sound emitting circuit 21.
is activated and a sound is emitted to notify the registrant of an incorrect signal input. At the same time, the control signal output from the fourth output terminal 20b is input to the remote control function control circuit 14. As a result, the remote control function control circuit 14 uses the DTMF of "1" and "2" stored and registered in the password registration circuit 16 by the above operation.
The signal is instantly erased and the device returns to the operating state where storage and registration are possible. Next, make sure to operate the push button switch 12 to register the PIN numbers "1", "2", and "3", where each of the three digits corresponds to a number from 0 to 9. Since the DTMF signal corresponding to "1" is identified by the registered signal identification circuit 20 as a DTMF signal corresponding to the numbers 0 to 9,
The DTMF signal corresponding to "1" is output from the fifth output terminal 20.
The password is stored and registered in the password registration circuit 16 via c. Next, the DTMF signal corresponding to "2" is also identified by the registration signal identification circuit 20, but the same as the DTMF signal corresponding to "1", the registration signal identification circuit 20
PIN number registration circuit 1 via the fifth output terminal 20c of
6 is stored and registered. Furthermore, it corresponds to "3"
The DTMF signal is also identified by the registration signal identification circuit 20, and is stored and registered in the password registration circuit 16 via the fifth output terminal 20c of the registration signal identification circuit 20, like the DTMF signals corresponding to "1" and "2". Therefore, each DTMF signal corresponding to the numbers 0 to 9 of the three-digit password number "1", "2", and "3" is stored and registered in the password registration circuit 16. When the memory registration operation is completed, by opening the password registration switch 13, the remote control function control circuit 14 places the password registration circuit 16 in the memory registration holding state, and also activates the registration signal identification circuit 20 and the error signal sound emitting circuit 21. make it inoperable. Through the above-described PIN registration operation, the PIN registration device of the telephone device of the present invention emits a sound when an erroneous signal, ie, a signal that does not perform memory registration, is input to notify the registrant that an erroneous signal has been input. At the same time, it can be said that it has a function of erasing the memorized and registered contents up to the time when an erroneous signal is input so that the password memorization and registration operation is performed from the beginning.

Next, the operation of a telephone device using the telephone password registration device of the present invention will be described with reference to the drawings. First, a changeover switch (not shown) is set so that the telephone device is in an automatic answering machine state and the telephone circuit 9 is in an inactive state. In such a state, a calling signal is sent to the telephone device from connection terminal 1,
When a call arrives via 1', the incoming call circuit 2 first detects it and applies a control signal to the answering function control circuit 8. As a result, the answering function control circuit 8 activates the closing circuit 22 to close the closing switch 3 and put the telephone line into a talking state, and also controls the message memory circuit 7 to retrieve the previously stored response message. Send to caller. At this time, the remote control function control circuit 14 also receives the control signal from the answering function control circuit 8 and switches the output terminal of the switch circuit 19 to the first output terminal 19a. And answering function control circuit 8
Detects a beep tone after the message memory circuit 7 completes transmission of the response message, sets the unstored portion of the message memory circuit 7 to a memorizable state, and converts the message sent by the caller in response to the response message into an incoming message. The message is stored in the message memory circuit 7 as . In this case, since the PIN number is not transmitted via the telephone line, the first output terminal 19a of the switch circuit 19
PIN code is not added to . Then, when the owner makes a call operation to listen to the incoming messages from outside while the incoming messages of several callers are stored in the message memory circuit 7, the ringing signal is first connected via the telephone line. Terminal 1, 1'
A ringing signal is applied to the incoming circuit 2 through the terminating circuit 2. Thereby, the incoming call circuit 2 applies an output signal to the answering function control circuit 8. Therefore, the answering function control circuit 8 outputs control signals to the closing circuit 22, the message memory circuit 7, and the remote control function control circuit 14. The closing circuit 9 closes the closing switch 3 to put the telephone line into a talking state, and the message memory circuit 7 sends a response message to the closed telephone line via the first line transformer 4. At the same time, the remote control function control circuit 14 switches the output of the switch circuit 19 so that it is output from the first output terminal 19a. Then, when the owner confirms the end of the response message and sends a DTMF signal corresponding to the PIN number via the telephone line, the DTMF signal is transmitted to the first output terminal 19 of the switch circuit 19.
It is added to the password identification circuit 15 via a. The PIN identification circuit 15 generates a DTMF signal corresponding to the transmitted PIN and the PIN registration circuit 16.
The password detection circuit 17 compares the DTMF signal corresponding to the password stored and registered in the password detection circuit 17, and if the password is different, the remote control function control circuit 14
However, if they are the same, a control signal is output to the remote control function control circuit 14. The remote control function control circuit 14 receives the control signal.
connects the output end of the switch circuit 19 to the second output terminal 19
At the same time, a control signal is applied to the answering function control circuit 8, and the message memory circuit 7 is operated by the answering function control circuit 8 to reproduce the incoming message. When the owner hears the playback of the incoming message and transmits a remote control signal via the telephone line, the remote control signal is transmitted to the remote control signal identification circuit 18 via the connection terminals 1 and 1' and the second output terminal 19b of the switch circuit 19. , the signal for which remote control operation is to be performed is identified and applied to the remote control function control circuit 14. The remote control function control circuit 1
4, a control signal corresponding to the output signal of the remote control signal identification circuit 18 is sent to the answering function control circuit 8;
Upon receiving the control signal, the answering function control circuit 8 controls the message memory circuit 7 in response to the remote control signal transmitted by the owner.

Next, when a changeover switch (not shown) is set so that the telephone equipment receives only a call signal from a specific person, the call signal from a certain caller will first pass through the connection terminals 1 and 1' via the telephone line. When connected to the incoming call circuit 2, the incoming call circuit 2 issues a control signal to the answering function control circuit 8. As a result, the answering machine function control circuit 8 sends a control signal to the remote control function control circuit 14, switches the output terminal of the switch circuit 19 to the first output terminal 19a, and also sends a control signal to the message memory circuit 7, and sends a control signal to the remote control function control circuit 14. Please send a response message to the caller, and if the caller is not a specific person, the message will respond to the PIN sent via the telephone line.
The DTMF signal is applied to the password identification circuit 15 from the first output terminal 19a of the switch circuit 19. The PIN identification circuit 15 compares the DTMF signal of the PIN registered in the PIN registration circuit 16 and the DTMF signal of the transmitted PIN in the PIN detection circuit 17, but since they do not match, the PIN No output signal can be output from the identification circuit 15 .
On the other hand, in the case of a specific person, since the person knows the PIN number, the PIN number detection circuit 1 of the PIN identification circuit 15
At step 7, the DTMF signal of the password stored and registered in the password registration circuit 16 matches the DTMF signal of the transmitted password, and the password identification circuit 15 outputs an output signal to the remote control function control circuit 14. do. As a result, the remote control function control circuit 14
outputs a control signal to the answering machine function control circuit 8 and telephone circuit 9. The answering function control circuit 8 receives the control signal to control the message memory circuit 7.
Stop controlling. On the other hand, in the telephone circuit 9, a control signal operates a ringer sound generating circuit (not shown) to emit a ringing sound, so that the owner can take the handset 10 connected to the telephone circuit 9 off-hook. As a result, the switch 11 is also turned off, and a call can be made using the handset 10 via the second line transformer 5 and the telephone circuit 9.

(g) Effects of the invention The PIN number registration device for a telephone device of the present invention generates a PIN number by operating a pushbutton switch.
Corresponds to numbers 0 to 9 in the DTMF signal
The password is configured using DTMF signals, and even if you accidentally try to register it by operating the "*" or "#" push button switch, the erroneous signal sound emitting circuit will emit a sound and the error will occur. It not only tells you when you have operated the wrong push button switch, but also automatically erases the information you registered before operating the wrong push button switch, making it easy and reliable. It is now possible to register a multi-digit PIN number in which each digit is a DTMF signal corresponding to the numbers 0 to 9. Furthermore, since the special keys "*" and "#" are not used, the DTMF signals corresponding to "*" and "#" can now be used for other purposes.
