It becomes a state to do.
As a result, the digital signal read from the response message memory circuit (17) is transferred to the second voice conversion circuit (2
It is input to 2) and converted into an audio signal. The signal converted into the audio signal by the second audio conversion circuit (22) is input to the reproduction amplification circuit (26) through the switch circuit (23), amplified, and then emitted by the speaker (27). . Therefore, the user can reproduce and listen to the response message stored in the response message memory circuit (17), and can confirm the content of the message. Although the response message storing operation and the reproducing operation are performed as described above, the automatic reception operation will be described below. Such an operation is performed by closing the automatic reception switch (5), but when such an operation is performed, the first operation is performed.
The output signal of the amplifier circuit (14) is output to the output terminal (16) of the switch circuit (15) and the switch circuit (23) is connected to the second output terminal (25) of the second audio conversion circuit (22).
The audio signal from is output. When a call signal arrives from the telephone line in such a state, the incoming circuit (2) to which the signal is input operates and its output signal is input to the control circuit (10). When a signal from the incoming circuit (2) is applied to the control circuit (10), the control circuit (1)
0) outputs a signal for operating the closing circuit (11) and the second voice conversion circuit (22) and outputs a signal for reading the response message memory circuit (17) to an operating state. When the closing circuit (11) is in an operating state, the closing switch (3) is closed, and the telephone line is closed. When such a closing operation is performed, the response message stored as a digital signal in the response message memory circuit (17) is read and input to the second voice conversion circuit (22) and converted into a voice signal. . The response message converted into the voice signal by the second voice conversion circuit (22) is input to the second amplification circuit (28) through the switch circuit (23) and amplified, and then the line transformer (4).
To the caller. When the operation of sending the response message is completed, the control circuit (10) switches to a state in which the message from the caller is stored.
When such a switching operation is performed, a second voice conversion circuit (22)
Also, the response message memory circuit (17) becomes inoperative and the first voice conversion circuit (21) becomes active. Also, the first memory circuit (18) provided for storing the message from the caller is set to the write operation state. In such a state, the message from the caller is input to the first amplifier circuit (14) through the line transformer (4), amplified, and then input to the first voice conversion circuit (21) through the switch circuit (15). It The message from the caller input to the first voice conversion circuit (21) is converted into a digital signal and then written to the writing terminal (18) of the first memory circuit (18).
It is applied to a) and stored in the first memory circuit (18). The operation of storing the message from the caller is performed,
When a predetermined time, that is, a time set in consideration of the capacity of the first memory circuit (18) has elapsed, the closing operation by the closing circuit (11) is released and the answering machine automatic answering device returns to a state of performing an automatic answering operation. To do. In this way, the automatic response operation, that is, the operation of storing the message from the caller in the first memory circuit (18) after transmitting the response message to the caller is performed, but the message from the caller for the next incoming call is The storage operation is performed by the second memory circuit (19), and the storage operation of the message from the caller for the next incoming call is performed by the third memory circuit (20).

Is entered. The message input to the reproduction amplifier circuit (26) is amplified and then applied to the speaker (27) to emit a sound, so that the user can hear the message from the calling party. When the reproduction switch (7) is closed again after the reproduction and listening operation of the message stored in the first memory circuit (18) is performed, the first memory circuit (18) is operated by the control circuit (10). Becomes inoperative and the second memory circuit (19) becomes in a reading operation, and the message stored in the second memory circuit (19) is emitted by the speaker (27). Can be heard. Further, when the reproduction switch (7) is closed next, the second memory circuit (19) becomes inoperative and the third memory circuit (20) becomes in a state of performing read operation. Since the message stored in (20) is emitted by the speaker (27), the message can be heard. Then, when the reproduction switch (7) is closed next, the third memory circuit (20) becomes inoperative and the first memory circuit (18) becomes in a state of performing the reading operation. In this way, each time the reproduction switch (7) is closed, the memory circuits in the read operation state are switched in order, and the stored message can be reproduced and listened to. Then, if the reproduction switch (7) is closed while the message stored in each memory circuit is being reproduced, the message stored in the next memory circuit is immediately reproduced. It is very convenient for playing and listening to messages from callers. As described above, the operation of reproducing and listening to the message from the caller stored in each memory circuit is performed. Next, the erasing operation will be described. Such a message erasing operation is performed by closing the erasing switch (8) while playing and listening to the message stored in each memory circuit. For example, when the erasing switch (8) is closed while the message stored in the first memory circuit (18) is being reproduced and listened to, the control circuit (10) causes the first memory circuit (18) to be provided. A signal for performing the erase operation is output to the erase terminal (18d), and the message stored in the first memory circuit (18) is erased. Thus the first memory circuit (18)
Although the erasing operation is performed, the erasing operations of the second memory circuit (19) and the third memory circuit (20) are also performed in the same manner, and the description thereof will be omitted. As described above, each operation in the present embodiment is performed. Next, the operation of call recording for recording the voice of the caller while the user is talking with the caller will be described. Such an operation is performed by closing the call recording switch (9) while the user is talking to the caller. When the call recording switch (9) is closed, the control circuit (10) causes the switch circuit (15) to output the signal from the first amplifier circuit (14) and the first voice conversion circuit ( 21) becomes active. In addition, the first memory circuit (18), the second memory circuit (19) and the third memory circuit (20) are in a state of continuously storing a call signal with the caller. Line transformer (4)
