The present invention relates to an answering machine.

(b) Conventional technology Recently, answering machines have appeared that are equipped with a function to record message messages that are sent only to a specific person. An example of such a device is one that records a transmitted message on an arbitrary part of a message recording tape. Some devices have two tracks, one for messages and one for messages, so that messages corresponding to each child track can be recorded. Furthermore, in devices that use semiconductor memory as a recording medium, for example, as in the case of the above-mentioned magnetic nerve board, a 7-conductor memory circuit is used to record both business messages and message messages.

The circuit (7> receives the address counted by the address detection circuit (39) after the operation,
A predetermined count number (28 to 4S) is subtracted from the address address and stored in the message information memory circuit (29) as the end message recording end 'f address address, and the count number of the message number counting circuit (28) is correspondingly stored. The display drive circuit (30
) is deactivated, the display is stopped, the message recording operation is completed, and the answering machine returns to the standby state of the answering machine mode.

Next, the reproduction operation of the recorded message as described above will be explained. First, switch for message playback (25

The sound is emitted from the speaker (17) through the fifth fixed terminal (33c) and the second amplifier circuit (16). In such a state, the memory control circuit (38) compares the address counted by the address detection circuit (39) with the recording end address, and detects that the counted address matches the recording end address. Then, when the address based on the count matches the recording end address, the memory control circuit (38) puts the message memory circuit (36) into a memory retention state and instructs the control circuit (7) to stop reading. give a signal. Thereby, the control circuit (7) reads the recording start address and the recording end address corresponding to the number of messages "2" from the message information memory circuit (29), and stores the recording start address in the memory control circuit (38). The address and recording end address are added, as well as the message and a control signal for placing the message memory circuit (36) in a read state. Further, the control circuit (7) controls the display drive circuit (30) to display the number of messages "2" on the display (31).

In such a state, the memory control circuit (38) compares the address counted by the address detection circuit (39) with the recording end address of the message number r2, and determines that the counted address indicates the end of the recording. The memory control circuit (38) waits until the address matches the recording end address, and then the memory control circuit (38) puts the business/message memo circuit (36) into a memory retention state, and the control circuit <7)
sends a signal to stop reading. As a result, the control circuit (
In step 7), an attempt is made to read the information regarding the address corresponding to the third message from the message information memory circuit (29), but since it is not stored, a beep sound signal is added to the speaker (17) and the sound is emitted. A control signal is sent to the memory control circuit 38) to stop reading the message memory circuit (36), and at the same time, the display drive circuit (30) is deactivated and the display is turned off. The memo no control circuit (38> is D/
The A conversion circuit (35) is made inactive. This operation ends the operation of reproducing the message on the answering machine.

Next, a case will be described in which a message is played back by remote control. As in the case of recording a voice message, suppose that an external telephone sends a ringing signal to an answering machine, and the answering machine responds to the ringing signal and plays a response message. When a DTMF signal corresponding to a predetermined dial number is sent from an external telephone to the answering machine to reproduce the message, the answering machine will:
Upon receiving the DTMF signal, the DTMF signal is transmitted through the transformer (6).
It is detected by a signal detection circuit (26) and identified by a DTMF signal identification circuit (27). In such a situation, the DTMF signal identification circuit (27) identifies the transmitted DTMF signal as a signal for message reproduction.
The signal identification circuit (27) applies a command signal to start the message reproduction operation to the control circuit (7). Due to this operation, the control circuit (7) switches the input movable terminal (
32a) and the third fixed terminal (32d), and the connection between the output movable terminal (33a) of the output signal switching circuit (33>) and the fourth fixed terminal (33b), and the memory control circuit (38) A control signal is issued to stop only the reading of the response memory circuit (37), and the memory control circuit (38) stops reading of the response memory circuit (37) and maintains the operation of the D/A conversion circuit (35). Then, the control circuit reads the recording start address and the recording end address corresponding to the message number r1 from the information stored in the message information memory circuit (29), and reads out the recording start address and the recording start address. address and the memory control circuit (38
), and at the same time sends a control signal to put the message memory circuit (36) into a read state. Through this operation, the memory control circuit (38) controls the message/message memory circuit (36) to start reading out the message from the recording start address.Thereby, the message number 11 is read from the message/message memory circuit (36). The digitalized message is read out, converted into analog by the D/A conversion circuit (35), and sent to the third fixed terminal (33d).

Thereafter, in the same manner as in the case of manual operation, the control circuit (7) controls the memory control circuit (38) and sends the message number r2'' to the external telephone from the telephone line (1). Then, the memory control circuit (38) detects a match between the address counted by the address detection circuit (39) and the recording end address of the number of messages "2", and the message memory circuit (36) By causing the memory retention state and sending a signal to the control circuit (7) to stop reading, the control circuit (7) receives information regarding the address corresponding to the third message from the message information memory circuit (29). I try to read it out, but it is not stored, so I output the beep sound signal to the fourth fixed terminal (33) of the signal switching circuit (33).
In addition to 33b), it is also transmitted to the external telephone. Then, the control circuit (7) issues a control signal to the memory control circuit (38) to stop reading the message and message memory circuit (36), and also controls the line closing relay circuit (4>) to control the hook switch ( 5) is opened.The memory control circuit (38) disables the D/A conversion circuit (35) in response to a control signal from the control circuit (7>).
