Abstract

PURPOSE:To detect that a third person tries to listen to messages during user's absence by providing a means where reception of a password number is stored whether the password number is correct or not. CONSTITUTION:A push-phone signal receiver 13 decides whether the inputted signal is a password number or not; and when it is not a password number, the device is set to a normal recording mode. When it is a password number, it is sent to a computer 18 and is recorded in a RAM 21 and is compared with the password number registered in the RAM 21. When they coincide with each other, the mode is switched to the remote control permission mode, and recorded messages are reproduced and are sent to a line. If they are different, an error tone is sent to report the error of the password number. When an operation button 17 is depressed, input or non input of the password number during user's absence is displayed to detect whether a third person does wrong or not.

Description

[Detailed description of the invention] [Industrial application field 1 The present invention relates to an answering machine.

[Prior Art] Recent answering machines have functions that allow the subscriber to remotely check the contents of recorded messages and change response messages by inputting a personal identification number from outside the home. , and are now equipped with many functions such as a function as a room monitor.

[Problem B to be solved by the invention] However, in such conventional answering machines, it is difficult for a third party to decipher the PIN number and play a trick.
There have been cases where recorded messages have been illegally listened to, creating problems in terms of confidentiality. With conventional devices, even if a PIN number is decrypted and a message is illicitly retrieved, no evidence remains, so there is no plain text to confirm this, and there is a risk that the PIN number will be overlooked.

An object of the present invention is to provide an answering machine that can be remotely controlled by inputting a PIN number, and is capable of notifying the subscriber that a third party other than the subscriber has attempted to input the PIN number. The purpose of the present invention is to provide a telephone answering machine that provides a convenient answering machine.

[Means for Solving the Problems] The object of the present invention is to provide a means for detecting whether or not a PIN number has been input via a line, and a means for detecting whether or not a PIN number has been input via a line, and a means for detecting whether or not a PIN number has been inputted by the detection means. a means of memorizing the
This is achieved by an answering machine characterized by comprising means for informing whether or not the input of a password is stored in the storage means.

[Function] The answering machine of the present invention has means for remembering that the PIN number has been received, regardless of whether the PIN number is correct or not. It becomes possible to know whether the person has heard the message or tried to hear the message.

[Example] Next, examples of the present invention will be described.

FIG. 2 is a block diagram showing the configuration of an embodiment of the answering machine of the present invention. Figure 3 shows an example of a PIN number used to access messages recorded on an answering machine, and consists of a 4-digit number and the symbol "#" before and after the number. In the figure, 11 is a line input terminal, 14 is an incoming call detection circuit, 13 is a button signal receiver for detecting a PIN number, 15 is a voice synthesis circuit for reproducing a predetermined message, and 16 is a PIN number detection circuit. a display circuit 12 for displaying whether or not the message has been received; a speech network 18 for transmitting a reproduced message to the line; and a speech network 18 for transmitting a button signal among the received voice signals to a button signal receiver 13; is a microcomputer that controls the entire device. This microcomputer has input/output board 19.
The signal processing device 2 has an ORAM (random access memory) 21.

The RAM 21 has an area 22 for storing data indicating that a password has been received from the button signal receiver.
and an area 23 in which a pre-registered password is stored. Reference numeral 17 is an operation button for displaying on the display circuit 16 whether or not the identification number has been received while the user is away.

The operation of this answering machine will be explained below using the flowchart shown in FIG. When there is an incoming call and a calling signal is input from the line input terminal 11, the incoming call detection circuit 14 detects this and notifies the microcomputer 18 of the incoming call (step S1). Speech synthesis circuit 15 via 19
A command is given to reproduce the response sentence, and the reproduced response sentence is transmitted to the line through the speech network 12 (step S2). During or after sending the response sentence, when the other party presses the button on the telephone and a button signal is input, this signal passes through the speech network 12 and is sent to the button signal receiver 13. . The button signal receiver 13 determines whether or not this signal is a PIN number (step S3). If it is not a PIN number, the device is set to normal mode and a recording device (not shown) records the other party's message. Permit (step S4).

If it is a personal identification number, this personal identification number is converted into a signal readable by the microcomputer, and this signal is sent to the microcomputer 18. The microcomputer 18 records the input of the password in the area 22 in the RAM 21, regardless of whether the input password is correct or not.
(step 35), microcomputer 1
The signal processing device 20 of No. 8 inputs the input password and the RAM.
21 and the password registered in the area 23, and if they are the same, the system shifts to the remote control mode (step S7). For example, a recording device (not shown) plays a message recorded therein. transmission to the line. If these are mutually exclusive, an error tone is sent to the line to inform the other party that the password is incorrect (step S8).

This completes the sequence.

When you press the operation button 17 to check the messages you received while you were away, the microcomputer 18 checks the data in area 22 in the RA) 421 to see if your PIN was entered while you were away, and then enters the PIN. As the 0 display circuit 16 that displays an input to that effect on the display circuit 16 when there is an input, an LED (light emitting diode), an LCD (liquid crystal element), or the like can be used.

In the above embodiment, the RI 1421 is used as a means to remember that the PIN number has been input while the user is away.
A predetermined message, for example, "Please enter your password." may be played back and recorded on a recording device such as a tape recorder.

Further, instead of displaying on the display circuit 16 that a password has been input, the voice synthesis circuit 15 may play a predetermined message such as "A password has been input.j".

[Effects of the Invention] The answering machine of the present invention has a means for memorizing the fact that the PIN has been received regardless of whether the PIN is correct or not. It is possible to know whether a message has been fraudulently heard or attempted to be heard illegally, and in such a case, measures such as changing the password can be taken.
