Abstract

PURPOSE:To distinguish a general caller and a specific caller clearly by using a number collation means so as to collate a caller identification number with a telephone number of a desired opposite party stored in a memory circuit when the caller identification number from the caller is received in a message recording state and storing the telephone number in a storage circuit when they are coincident. CONSTITUTION:When a reply message is recorded on a reply tape 8 via a microphone 12 in advance, then an automatic reply switch 22 is operated to activate a control circuit 7 and an input signal changeover circuit 13 is connected to an output signal changeover circuit 15 to await a detection signal from a call signal detection circuit 3. When a call signal from the caller is sent through a telephone line 1, the call signal detection circuit 3 detects it and a pass word corresponding to the caller identification signal is detected by a detection circuit 26 simultaneously, the signal is fed to the circuit 7 to activate a caller number memory circuit 30 thereby restarting the message recording.

Description

[Detailed Description of the Invention] (A) Industrial Application Field The present invention relates to an answering machine that records business messages sent from a caller, and in particular only messages sent from a specific caller. The present invention relates to an answering machine that plays a message.

(b) Conventional technology Recent answering machines have a calling function,
In addition to recording general business messages in response to response messages, we also record messages as voice messages in a separate section from the section where general business messages are recorded using the PIN code sent by a specific caller. There are some that have the ability to display. For example, such a recording technique uses a magnetic tape as a recording medium, and as disclosed in Japanese Patent Publication No. 59-39943, it is possible to specify a track for recording general messages and a message recording track on a magnetic tape. There is a device that is equipped with a track for recording messages from the caller and selectively records the caller, and a device using a semiconductor memory circuit as a recording medium is disclosed in Japanese Patent Application Laid-Open No. 61-288543. As disclosed in the publication, a semiconductor memory circuit for recording messages from a specific caller such as a voice message is provided separately from a semiconductor memory circuit for recording general messages, and each message is recorded in each semiconductor memory circuit. I'm trying to record it.

(c) Problems to be Solved by the Invention In the above-mentioned answering machine, in order to record messages from a specific caller, a separate recording section (track) is used to record messages from a specific caller. (Semiconductor memory circuit, etc.) is installed to record a message from a specific caller in a separate recording section, but it is not cost-effective to provide a dedicated section for recording and playback. As the cost increases, the configuration becomes more complicated. Furthermore, the frequency of use of such a dedicated section is lower than that of the section for recording general business messages, and such answering machines do not display a message indicating that a call has been received from a specific caller. However, since there is generally more than one specific caller,
The only way to know which incoming calls and messages from a particular caller are being recorded is to play back and listen to the messages.

In order to solve such problems, the present invention has an economical structure that allows messages from general callers and messages from specific callers to be distinguished and recorded, and also includes display means to record messages from specific callers. To provide an answering machine by which it can be seen at a glance which caller's message has been recorded.

(d) Means for Solving the Problems The answering machine of the present invention comprises: a recording medium for recording and reproducing a business message; a recording position detecting means for detecting a starting position of message recording on the recording medium; A memory circuit for storing the recording position detected by the recording position detection means, a telephone number memory circuit for memorizing the telephone number of the desired party used for automatic dialing operation, and a , a dialing signal detection means for receiving a calling party identification number constituted by the transmitted dialing signal; and a dialing signal detecting means for receiving a calling party identification number constituted by the dialing signal being transmitted, and a telephone number in the telephone number memory circuit and the calling party identification number received by the dialing signal detection means. a number verification means for performing a verification operation; a control means for performing memory retention control of the recording position stored in the storage circuit by receiving a match output from the number verification means; and a reproduction control means for reproducing the message from the recording medium according to the recording position in the storage circuit.

(*) Function The answering machine of the present invention first sends out a response message, and when the message is being recorded, when the caller identification number is sent from the caller via the telephone line, The caller identification number is received by the dial signal detection circuit, and the number verification means compares it with the telephone number of the desired party stored in the telephone number memory circuit, and when a match is detected by the recording position detection circuit by the control means. The recording position of the business message on the recording medium is stored in a storage circuit, and when a selective playback operation is performed, the reproduction control means records the specific caller's business message from the recording medium according to the recording position stored in the storage circuit. This allows messages to be played back.

Next, when a response message is sent and a caller identification number is sent from the caller via the telephone line while the message is being recorded, the dial signal detection circuit detects the caller identification number. and in the number verification means, the number is verified against the telephone number of the desired party stored in the telephone number memory circuit and corresponding to each automatic dialing operation button;
When a match is made, the control means causes the storage circuit to store and hold the recording position of the business message on the recording medium detected by the recording position detection circuit, and information regarding the automatic dialing operation button corresponding to the telephone number matched by the number matching means. The memory circuit stores information corresponding to the recorded recording position, and the display means displays information regarding the automatic dialing operation button stored in the memory circuit to indicate by whom the recording is made, and performs a selective playback operation. In contrast, the reproduction control means reproduces the specific caller's message from the recording medium according to the recording position stored in the storage circuit.

A calling number memory circuit (31) stores a calling party identification number (also known as a PIN number) constituted by a DTMF signal. If there is a telephone number that matches the calling party identification number in the number verification circuit that performs a matching operation between the calling party identification number and the telephone number stored in the telephone number memory circuit (28), the telephone number is The number of the corresponding automatic dialing operation button is stored in addition to the message information memory circuit (to be described later).

In the figure, if Message 2 and Message 5 are message messages from a specific caller, the count number a at the recording start position of Message 2 and the count number at the recording end position as shown in Figure 4. At the same time, the number of the automatic dial operation button indicating who is the caller of the message is stored.Similarly, for message 5, the count number C of the recording start position and the count C of the recording end position are stored.

If the numbers of the automatic dialing operation buttons indicating a plurality of callers are fully memorized, the numbers are displayed one after another.

The recording and playback operations of a specific caller in the answering machine shown in FIG. 1 and configured as described above will now be described.

First, it is assumed that a response message is previously recorded on the response tape (8) via the microphone (12). In such a situation, the automatic response set switch (
22), and under the control of the control circuit (7), the input signal switching circuit (13) allows the input movable terminal (13e) to be connected to the fourth terminal (13d), and the output signal switching circuit (15)
), the output movable terminal (15a) is connected to the fifth terminal (15b).
At the same time, the control circuit (7) enters a state in which it waits for a detection output from the calling signal detection circuit (3), and is set in a standby state for automatic response. In such a state, when a calling signal is transmitted from the calling party via the telephone line (1), the calling signal detection circuit (3) applies a detection output to the control circuit (7>). The circuit (7) controls the line closing relay circuit (4), closes the hook switch (5), stops the transmission of the ringing signal, and
Motor drive circuit (18), plunger drive circuit (19)
) and starts playing the response tape (8).

By this reproduction run, the response message recorded on the response tape (8) is reproduced by the response head (10), and the response message is transferred from the fourth terminal (13d) of the input signal switching circuit (13) to the manual movable terminal ( 13e) - First amplifier circuit (14>) - Output movable terminal (15a) of output signal switching circuit (15) - Fifth terminal (15b) - Transformer (6) - Hook switch (
5) - Joins the telephone line (1) via the connection terminal 2),
Sent to caller. Upon completion of sending the response message, the control circuit (7) connects the input movable terminal (13e) of the input signal switching circuit (13) to the first terminal (13a), and connects the input movable terminal (13e) of the input signal switching circuit (13) to the output terminal (13a) of the output signal switching circuit (15). Movable terminal (15
a) is connected to the eighth terminal (15e), the motor drive circuit (18) and the plunger drive circuit (19) are controlled, and the message tape (9) is run for recording and the response tape (8>) is connected. The control circuit (
7) receives the count number for the recording start position of the business message to be recorded from the rotation detection circuit (20) that detects the running position of the business tape (9), and sends the count number at the recording start position to the message information. It is stored in the memory circuit (32). When a message is sent from the caller in such a state, the message is sent from the telephone line (1) to the connection terminal (2) - hook switch (5).
-) Lance (6) - First terminal (13a) of the human power signal switching circuit (S) - Movable terminal for human power (13e) - First amplifier circuit (14) - Movable terminal for output (15a) - Eighth terminal ( 15
e), it is added to the message head (11) and recorded on the message tape (9). In such a state of message recording, the caller sends the DTMF corresponding to 1#.
Following the signal, a DTMF signal corresponding to the calling party identification number is transmitted in order, and the DTMF signal is transmitted to the connection terminal (
2)-hook switch (5)-) is detected by the DTMF signal detection circuit (26) via the lance (6).

The DTMF signal detection circuit (26) first detects the DTMF signal for "1#" that was transmitted first, adds the signal for "#" to the control circuit (7), and then the control circuit (7)
The motor drive circuit (18) and plunger drive circuit (19) are stopped at - time, and the message recording operation is muted. At the same time, the control circuit (7) becomes ready to receive the caller identification number.Therefore, following the signal for "#", the control circuit (7) receives a signal from the DTMF signal detection circuit (26). applying a signal for the received caller identification number to the calling number memory circuit (30) to cause storage of the caller identification number and corresponding to terminating the reception of the signal for the caller identification number; Motor drive circuit (18>, Brazil)
The - time stop of the drive circuit (19) is canceled and the message recording operation is restarted. Furthermore, since the calling party identification number is stored in the calling party number memory circuit (30) as described above, the number matching circuit (31) is activated and the calling party number memory circuit (30) The caller identification number stored in the telephone number memory circuit (28) is compared with the telephone number stored in the telephone number memory circuit (28). Assuming that there is a telephone number that matches the caller identification number through such matching operation,
The number matching circuit (31) applies a -dissipated output to the control circuit (7) and sends the number "1" of the automatic dial operation button (24a) corresponding to the matched telephone number to the message information memory circuit (32). Corresponding to and storing the information of the recording position of the business message, the calling number memory circuit (
30) is cleared. After that, if the calling party puts the calling party's phone on the hook to finish recording the business message, the control circuit (7) responds to this operation by:
Motor drive circuit (18), plunger drive circuit (19)
) is deactivated to stop the running of the business tape (9), and the line closing relay circuit (4) is controlled to open the hook switch (5), and the input signal switching circuit (shi) and the output signal switching circuit are activated. (translation) disconnects the connection between each terminal and puts it into an automatic response standby state. Furthermore, the control circuit (7) receives the count number for the recording end position of the message recorded on the business tape (9) from the rotation detection circuit (20), and stores the count number for the recording end position in the message information memory circuit. (32) is stored so as to correspond to the count number of the recording start position, and the message information memory circuit (32) stores the number r1 of the automatic dial operation button (24a) for identifying the caller. Therefore, the count number of the recording position stored in the message information memory circuit (32) is stored and the number r1. of the automatic dial operation button (24a) is sent to the display drive circuit (33). In addition to the displayed information, display the number "1" on the display (34) and press the automatic dialing operation button (24a).
The owner is informed that a message from the other party at the telephone number corresponding to "number r1" has been recorded. - On the other hand, if there is no telephone number that matches the caller identification number in the verification operation in the number verification circuit (31), the number verification circuit (31) adds a mismatch output to the control circuit (7) and The control circuit (7) is made to hold the mismatch information. Then, when the calling party performs an action to end the recording of the business message, the control circuit (7) responds to such action by:
Motor drive circuit (18), plunger drive circuit (19)
) is deactivated to stop the running of the business tape (9), and at the same time controls the line closing relay circuit (4) to open the hook switch (5) and input signal switching circuit (13) and output signal switching circuit. Allow the connection between each terminal of (1 country) to be disconnected,
Set the automatic response standby state, and turn on the rotation detection circuit (2).
0), the count number for the recording end position of the message recorded on the message tape (9) is received, but according to the discrepancy information, it is not stored in the message information memory circuit (32), and the message information memory circuit (3
2) The count number for the recording start position stored in the memory is erased. In addition, if the caller does not send a DTMF signal for the caller identification number in the message recording state, the control circuit (7) transmits the signal for "#" from the caller and the caller's Since the signal for the identification number is not received and the output from the verification operation from the number verification circuit (31) is not received, the count number for the recording end position of the business message is received from the rotation detection circuit (20). Also, the message information memory circuit (32) does not store the count number, but upon receiving the count number for the recording end position, the count number for the recording start position stored in the message information memory circuit (32) is erased. That's what I do.

In this manner, only those callers who send out a caller identification number that matches the telephone number stored in the telephone number memory circuit (28) are stored as specific callers. Next, the operation of reproducing only the message of a specific caller from the message of interest recorded as described above will be explained. First, an explanation will be given of an operation in which the owner of the answering machine manually selects and reproduces only a specific caller. For example, assume that two message messages from a specific caller are recorded on the message tape (9), message 2 and message 5, as shown in FIG.
), the automatic dial operation button (number r1 of z4a> corresponding to the caller of message 2) and the number "2" of the automatic dial operation button (24b) corresponding to the caller of message 5 are set. are alternately applied to the display drive circuit (33), and the display (34)
Assuming that the messages are displayed alternately at regular intervals, by operating the selection playback switch (23) in such a state, the control circuit (7) first responds to such an operation and displays the message information memo circuit (32). reads the count number a of the recording start position for the business condition 2 from the information stored in the memory, and controls the motor drive circuit (18) so that the count number of the rotation detection circuit (20) matches the count number a; At the same time, the message tape (9) is rewound, and only the number "1" of the automatic dial operation button (24a) for the caller of message 2 is added to the display drive circuit (33). "rl" is displayed on the device (34). Furthermore, after starting to rewind the business tape (9), the control circuit (
7) is the input movable terminal (1) of the input signal switching circuit (13).
3e) and the third terminal (13c), and also connect the output movable terminal (15a) of the output signal switching circuit (15) and the sixth terminal (15c). Then, at the same time that the counts of the rotation detection circuit (20) match, the control circuit (7) controls the motor drive circuit (18) and the plunger drive circuit (19) to Message 2 was played back and recorded on the message tape (9).
A specific caller's message is played back via the message recording/reproducing head (11), and the input signal switching circuit (13)
3rd terminal (13c) - movable terminal for human power (13e) - 1st amplifier circuit (14) - movable terminal for output (15a) - 6th
Terminal 2 via terminal (15c) - second amplifier circuit (16)
The business message is emitted from the speaker (17), and the message information memory circuit (32)
The count number of the mulberry recording end position for the task 2 stored in the memory is read out, and the state waits for the count number of the rotation detection circuit (20) to match the read count number.

Then, when the count number of the rotation detection circuit (20) matches the count number of the recording end position, the control circuit (7>) uses the information stored in the message information memory circuit (32) to generate the next one. The count number C at the recording start position for the message 5 is read out, the plunger drive circuit (19) is controlled, the message recording/playback head (11) is moved from the playback position to the standby position, and the count number C is read out. The motor drive circuit (18) is controlled to fast-forward the message tape (9) so that the counts of the rotation detection circuit (20) match, and the message 5 is sent to the display drive circuit (33). Number 12 of the operation button (24b) for automatic dialing for the caller
" is added, and "2" is displayed on the display (34). When the counts of the rotation detection circuit (20) match, the control circuit (7) controls the motor drive circuit (18) and the plunger drive circuit (19),
The message tape (9) is played back, and the message tape (9) is played back.
9), a specific caller's message is played back as the message 5 recorded in the message recording/playback head (11);
Third terminal (13c) of input signal switching circuit (S) - Manual movable terminal (13e) - First amplifier circuit (14) - Output movable terminal (15a) - Sixth terminal (15c) - Second amplifier circuit (16), the message as message 5 is emitted from the speaker (17), and the count number d of the recording end position for message 5 stored in the message information memory circuit (32) is output. The rotation detection circuit (20) waits until the count number of the rotation detection circuit (20) matches the count number d.
When the count number 20) matches the count number d at the recording end position, the control circuit (7) attempts to read out information regarding the next message from the specific caller from the message information memory circuit (32). However, since the message information memory circuit (32) does not store the message, a beep sound signal is added to the speaker (17) and a sound is emitted to notify the owner of the end of playback, and the motor drive circuit (18)
The plunger drive circuit (19) is made inactive, and the display drive circuit (33) is again set to the number "1" of the automatic dial operation button (24a) corresponding to message 2 and message 5. The number “2” on the automatic dial operation button (24b)
'' are added alternately and displayed on the display (34) at regular intervals, thus ending the reproduction of the specific caller's message. Next, a description will be given of an operation for selectively reproducing a message to be sent by a specific caller by remote control (operated from an external telephone). As in the case of manual operation, two message messages from specific callers, message 2 and message 5, are recorded, and the numbers "1" and "r2" are displayed on the display (34). Suppose that they are displayed alternately. First, an external telephone sends a calling signal to the main answering machine, causing the answering machine to send a response message.

In such a playback state, the external telephone calls, for example, "
”, the DTMF signal is sent to the connection terminal (2) - hook switch (5) - transformer (
6) to the DTMF signal detection circuit (26). The DTMF signal detection circuit (26) detects it with a longer detection time than the recording state, and the DTMF signal for 'axe' is detected as DTM.
Via the F signal detection circuit (26), it is detected as a selective reproduction command signal by the selective reproduction command signal detection circuit (27).

Corresponding to such operation, the control circuit (7) controls the motor drive circuit (18) and the plunger drive circuit (19),
At the same time as stopping the reproduction of the response tape (8), the count number a of the recording start position for message 2 is read from the information stored in the message information memory circuit (32), and the rotation detection circuit is set to the count number a. The motor drive circuit (18) is controlled so as to match the count number of (20), and the message tape (9) is rewound, and the display drive circuit (33) is automatically - Add only the number "r1" to the dial operation button (24a) and display "11" on the display (34). Furthermore, the control circuit (7
) is the movable input terminal (1) of the input signal switching circuit (13).
3e) - the third terminal (13e) is connected, and the output movable terminal (15a) of the output signal switching circuit (15) - the fifth terminal (15c) are connected. And the rotation detection circuit (
20) is the count number a at the recording start position.
At the same time, the control circuit (7) operates in the same manner as in the manual operation described above, and the specific caller's message as message 2 recorded on the message tape (9) is The input signal is reproduced by the head (11), and the third terminal (13c) of the input signal switching circuit (13) - the input movable terminal (13e) - the first amplifier circuit (14) - the output movable terminal (15a) - the fifth
Terminal (15c) - Transformer (6) - Hook switch (5
) - passes through the connection terminal (2) and joins the telephone line (1),
Sent to an external phone. Message 2 is thereby listened to on an external telephone. Thereafter, the control circuit (7) operates in the same manner as in the manual operation, and after reproducing the message of matter 2, the display (34) is activated to reproduce the message of matter 5. ) is displayed, and the message of the matter 5 is played back. At the same time as starting the reproduction operation of the message for message 5, the control circuit (
7) reads the count number d of the recording end position for the message information memory circuit (32) for the message 5, and determines that the count number of the rotation detection circuit (20) matches the count number d. I'm in a state of waiting for it to happen.

Then, when the count number of the rotation detection circuit (20) matches the count number d at the recording end position, the control circuit (7) stores information regarding the next business message from the specific caller in the message information memory. Although an attempt is made to read the message information from the circuit (32), it is not stored in the message information memory circuit (32), so a beep sound signal is added to the fifth terminal (15c) of the output signal switching circuit (15), and the external telephone and notifies the end of regeneration, and also puts the motor drive circuit (18) and plunger drive circuit (19) into an inoperable state, controls the line closing relay circuit (4), and opens the hook switch (5). let Kirani display drive circuit (
33), the number 11 of the automatic dialing operation button (24a) for the caller of Message 2 and the number ``2'' of the automatic dialing operation button (24b) corresponding to the caller of Message 5 are returned.
are added alternately and displayed on the display (34) at regular intervals to finish playing the specific caller's message.In this embodiment, the magnetic tape is The recording and reproducing operation of a specific caller using an answering machine configured using a semiconductor memory circuit as a recording medium has been described.Next, as another example, as shown in FIG. 2, an answering machine configured using a semiconductor memory circuit as a recording medium will be described.

In such a state, the automatic reception set switch (22) is operated, and the input signal switching circuit (35) connects the movable input terminal (35a) and the third fixed terminal (35d) by the control circuit (7). The output signal switching circuit (Ni) has a movable output terminal (36a) and a fourth fixed terminal (36a).
When the control circuit (7) is connected to (b), the control circuit (7) enters a state in which it waits for a detection output from the calling signal detection circuit (3), and is set in a standby state for automatic response. In such a state, when a calling signal from the calling party is successfully transmitted via the telephone line (1), the calling signal detection circuit (3) applies a detection output to the control circuit (7). Thereby, the control circuit (7) controls the line closing relay circuit (4), closes the hook switch (5), stops the transmission of the calling signal, and controls the memory control circuit (41). The response memory circuit (39) is brought into a reading state by the memory controller circuit (41), and the D/A converter circuit (38) is brought into an operating state.
9) is converted into an analog signal by the D/A conversion circuit (38), and the third fixed terminal (35d) of the input signal switching circuit (35) - the movable terminal for human power (35a> - First amplifier circuit (14) - Output movable terminal (36a) of output signal switching circuit (36) - Fourth fixed terminal (
36b) to transformer (6) to hook switch (5
) - is sent from the connection terminal (2) to the telephone line (1) as well as to the calling party. After the transmission of such a response message is completed, the control circuit (7) connects the movable input terminal (35a) and the first fixed terminal (35b) of the input signal switching circuit (35), and outputs the message. Signal switching circuit (36
) and the output movable terminal (36a) and the sixth fixed terminal (36
d), and also controls the memory control circuit (41).
), the response memory circuit (39) is released from the read state and the D/A conversion circuit (38) is rendered inoperable. Then, due to this operation, the memory controller circuit (4)
1) receives the address detected by the address detection circuit (42), puts the business memory circuit (40) into a writing state from the address, and allows activation of the A/D conversion circuit (37). Further, the address received by the memory control circuit (41) is also applied to the control circuit (7) via the address detection circuit (42), and the control circuit (7) converts the address to the recording start address of the message. as a message information memory circuit (
32). In such a state, when the caller has finished sending the message, the message is sent from the telephone line (1) to the connection terminal (2) to the hook switch (5).
) - transformer (6) - first of human signal switching circuit (35)
Fixed terminal (35b) - Movable terminal for human power (35a) - 1st
Amplifier circuit (14) - Output movable terminal (36a) - Sixth
The information is converted into a digital signal by the A/D conversion circuit (37) via the fixed terminal (36d), and is sequentially stored in the task memory circuit (40) which is in the writing state. In such a state of recording the business message, the caller sends the D corresponding to "#".
The TMF signal is followed by a DTMF corresponding to the calling party identification number.
When the signals are successfully transmitted, the DTMF signals are detected by the DTMF signal detection circuit (26) via the connection terminal (2), hook switch (5), and transformer (6). The DTMF signal detection circuit (26) first detects the DTMF signal for "#" that has been completely transmitted, and adds the signal for "#" to the control circuit (7), which then sends the signal to the memory control circuit. (41) to hold the memory circuit (40), and the A/D conversion circuit (3)
7) is made inactive, the message recording operation is muted, and stopped at -, so that the DTMF signal after the DTMF signal for "#" is not stored in the message memory circuit (40), and the control circuit (7) becomes ready to receive the calling party identification number.Therefore, the control circuit (7) follows the signal for "#", and the DTMF signal detection circuit (2)
6) adding a signal for the calling party identification number received from the calling party identification number to the calling party number memory circuit (30) to cause the calling party identification number to be stored and to finish receiving the signal for the calling party identification number; Correspondingly, the memory controller circuit (41) is controlled, the message memory circuit (40) is put into the writing state again, the A/D conversion circuit (37) is put into the operating state, and the message recording operation is temporarily performed. Unpause,
Resume recording operation. Furthermore, since the calling party identification number is stored in the calling party number memory circuit (30) as described above, the number verification circuit (31) is activated and stored in the calling party number memory circuit (30). The caller identification number received is compared with the telephone number stored in the telephone number memory circuit (28). If there is a telephone number that matches the caller identification number as a result of such a matching operation, the number matching circuit (31) applies a -dissipated output to the control circuit (7) and performs an automatic, e.g. The number "1" of the dial operation button (24a) is stored in the message information memory circuit (32) corresponding to the information of the recording address of the said business message, and the calling number memory circuit (30) is cleared. do. After that, if the calling party puts the calling party's phone on the hook to finish recording the business message, the control circuit (7) controls the memory control circuit (41) in response to this operation. ,
The business memory circuit (40) is put into a memory retention state, and the A/D
The conversion circuit (37) is deactivated to cancel the message recording operation, the line closing relay circuit (4) is controlled to open the hook switch (5), and the input signal switching circuit (35) and output are controlled. The connections between the respective terminals of the signal switching circuit (36) are released and the automatic response standby state is established. Furthermore, the control circuit (7) includes the memory controller circuit (
41), the message memory circuit (40) enters the memory retention state, and at the same time, the address number detection circuit (42)
receives the message recording end address from the message information memory circuit (32) and stores it in the message information memory circuit (32) so as to correspond to the recorded recording start address, and also corresponds to the matching output received from the number matching circuit (31). The start and end addresses stored in the message information memory circuit (32) and the automatic dialing operation button (24a)
The number "1" of the automatic dial operation button (24a) is stored in memory and the number "1" of the automatic dial operation button (24a) is stored in the display drive circuit (33).
In addition, the number "1" is displayed on the display (34) to notify the holder that the message from the specific caller has been recorded. On the other hand, the number verification circuit (
If there is no telephone number that matches the caller identification number in the verification operation in step 31), then the number verification circuit (31)
adds the mismatch output to the control circuit (7) and adds the mismatch output to the control circuit (7).
) to retain mismatch information. Thereafter, when the caller performs an operation to end recording the message, the control circuit (7) causes the memory controller circuit (41) to place the message memory circuit (40) in a memory retention state in response to such operation. , disables the A/D conversion circuit (37), cancels the message recording operation, controls the line closing relay circuit (4), and activates the input signal switching circuit (Japanese) and the output signal switching circuit ( (A) Disconnect the connections between each terminal and place the answering machine in an automatic answering standby state. Further, the control circuit (7) includes the memory control circuit (41).
), the message memory circuit (40) enters the memory retention state, and at the same time receives the message recording end address from the address number detection circuit (42). The end address is not stored, but the recording start address stored in the message information memory circuit (32) is erased. Furthermore, in the message recording state, if a DTMF signal for the caller identification number is not transmitted from the caller, the control circuit (7) The end of recording is detected by the address detection circuit (42) in response to the end of the business message because the signal for the personal identification number is not received and the output from the verification operation in the number verification circuit (31) is not received. Even if an address is received, the recording start address stored in the message information memory circuit (32) is deleted without being stored in the message information memory circuit (32).

In this manner, only those callers who send out a caller identification number that matches the telephone number stored in the telephone number memory circuit (28) are stored as specific callers. Next, the operation of reproducing only the message of a specific caller from the message of interest recorded as described above will be explained. First, a description will be given of an operation in which the owner of the answering machine manually selects and reproduces only a specific caller. For example, one message A is stored in the message memory circuit (40) as a message from a specific caller, and information regarding the message A includes a recording start address AI, a recording end address B2, and the message A. Only the number "8" of the automatic dial operation button (24h) for automatically dialing the phone number corresponding to the caller of the message is stored in the message information memory circuit (32),
The control circuit (7) adds the number 1″8″ of the automatic dial operation button (24h) to the display drive circuit (33).
Assume that "8" is displayed on the display (34). By operating the selection regeneration switch (23) in such a state, the control circuit (7) responds to such operation by switching between the input movable terminal (35a) and the third fixed terminal of the input signal switching circuit (35). (35d), and connect the output movable terminal (36a) of the output signal switching circuit (36) to the fifth fixed terminal (35d).
36c). Furthermore, the control circuit (7) reads the recording start address A1 and the recording end address B from the information stored in the message information memory circuit (32), and reads the recording start address AI and the recording end address B1. Memory control circuit (4
1) and the memory futon roll circuit (41
), a signal for selectively reproducing the task memory circuit (40) is added, and furthermore, "r8" is displayed on the display (34).
and display it. The memory control circuit (
41) puts the D/A conversion circuit (38) into operation according to the control of the control circuit (7), and also puts the task memory circuit (41) into operation.
0) from the recording start address A1. As a result, the specific caller's message as message A is read out from the message memory circuit (40),
It is converted into an analog by the D/A conversion circuit (38), and the third fixed terminal (35d) - the movable terminal for human power (35a) - the first amplifier circuit (14) - the movable terminal for output (36a) - the fifth fixed terminal (36c) - passes through the second amplifier circuit (16) to the speaker (
17) The sound is louder. While the message A is being played back, the memory control circuit (41) compares the address counted by the address detection circuit (42) with the recording end address of the received message A.Then, the memory control circuit (41) compares the address counted by the address detection circuit (42) with the recording end address of the message A received. advances, and the address detection circuit (42
) matches the recording end address of message A, the memory control circuit (41) puts the message memory circuit (4o) into a memory retention state and instructs the control circuit (7) to stop reading. Add the signal.

As a result, the control circuit (7) attempts to read the message information from the message information memory circuit (32), but since it is not stored, the control circuit (7) transmits the beep sound signal to the speaker (17). In addition, a signal is added to the memory control circuit (41) to notify the owner of the end of playback and to cancel the playback of the message, and the memory control circuit (41) disables the D/A conversion circuit (38). The operation ends the reproduction of the specific caller's message on the answering machine. As mentioned above, if multiple message messages from a specific caller are recorded instead of just one message, an address detection circuit (42) is installed at the recording end address of the message A. When the address addresses to be counted match and the memory control circuit (41) puts the business memory circuit into the memory retention state and applies a read stop signal to the control circuit (7), the control circuit (7) starts the read operation. Upon receiving the stop signal, the message information memory circuit (32) reads out the recording start address and recording end address for the next message, and sends the message information memory circuit (40) to the memory together with a signal to re-read the message. Control circuit (
41>, at the same time as the next message is played back, the control circuit (7) tells the display drive circuit (33) the number of the automatic dial operation button corresponding to the caller of the next message. The number is read out from the message information memory circuit (32) and added, and the number is displayed on the display (34).

Next, the operation of selectively reproducing business messages by a specific caller by remote control (operated from an external telephone) will be described. As in the case of manual operation, it is assumed that only one message for message A from a specific caller has been recorded and "8" is displayed on the display (34). , sends a call signal from the external telephone to the main answering machine, and causes the answering machine to send a response message. (During such automatic answering operation, the display (
34) is not displayed. ) In such a playback state, for example, DTMF for 'H' in order to perform a predetermined selective playback operation from the external telephone.
When the signal is transmitted, the DTMF signal is sent to the connection terminal (2) -
DTMF via hook switch (5)-transformer (6)
It is added to the signal detection circuit (26).

The DTMF signal detection circuit (26) detects with a longer detection time than the recording state, and the DTMF signal for "I" is
Via the MF signal detection circuit (26), it is detected as a selective reproduction command signal by the selective reproduction command signal detection circuit (27>). The input movable terminal (35a) and the third fixed terminal (35d) are connected, and the output signal switching circuit 36) is connected.
movable output terminal (36a) and fourth fixed terminal (36b)
and the memory control circuit (41
) is applied to stop reading of the response memory circuit (39), the memory control circuit (41) puts only the response memory circuit (39) into the memory retention state, and D
The operating state of the /A conversion circuit (38) is maintained. Then, in response to the response memory circuit (38) entering the memory retention state, the control circuit (7) inputs the recording start address A1 regarding the message A as information stored in the message information memory circuit (32). and the recording end address B1, and the memory controller circuit (41
) and the memory controller circuit (41).
A signal is applied to selectively reproduce the task memory circuit (40). Even in such a state, the control circuit (7) continues to display "8" on the display (34). In the memory control circuit (41), the control circuit (7)
), the task memory circuit (40) is controlled to start reading from the recording start address A1. As a result, the specific caller's message as message A is read out from the message memory circuit (4o), converted into analog by the D/A conversion circuit (38) in the operating state, and then transferred to the third fixed terminal. (35d) - Movable terminal for human power (35a) - First amplifier circuit (14> - Movable terminal for output (35a) - Fourth fixed terminal (35b) - Transformer (6) - Hook switch (5)
- Via the connection terminal (2) it joins the telephone line (1) and is sent to an external telephone. As a result, message A can be listened to on an external telephone.

While the message A is being reproduced, the memory control circuit (41) compares the address counted by the address detection circuit (42) with the recording end address of the received message A.

Then, as the playback progresses and the address counted by the address address detection circuit (42) matches the recording end address of message A, the memory control circuit (41) detects the message memory circuit (40). The memory is maintained and a read stop signal is applied to the control circuit (7).

As a result, the control circuit (7) attempts to read out the message information from the message information memory circuit (32), but since it is not fully stored, the control circuit (7) outputs the beep sound signal to the signal switching circuit (32). In addition to the fourth fixed terminal (36b) of the external telephone, a signal is sent to the external telephone to notify the end of playback, and a signal is added to the memory control circuit (41) to cancel the playback of the message. (41) disables the D/A conversion circuit (38), controls the line closing relay circuit (4), opens the hook switch (5), and sends a specific caller to the answering machine. Ends playing the message.

As mentioned above, if multiple message messages from a specific caller are recorded instead of just one message, the address detection circuit (42 ) match, the memory control circuit (41) puts the business memory circuit (40) into a memory retention state, and applies a reading stop signal to the control circuit (7), when the control circuit ( 7
) reads out the recording start address and recording end address regarding the next message from the message information memory circuit (32) upon receiving the reading stop signal, and puts the message memory circuit (40) into the rereading state. In addition, the control circuit (7) causes the display drive circuit (41) to read out the next message from the message memory circuit (40).
33), the number of the automatic dial operation button corresponding to the caller of the next message is read out from the message information memory circuit (32) and added, and the number is displayed on the display (34).
