In the message management area, information regarding the voice compression data is stored for each of the stored voice compression data.

The information is mainly mailbox number information for designating a message stored as voice compression data, a start address of a message stored in the message data area, and whether the message is a response message or a message. It is type information indicating whether the message.

When the message is reproduced, the mailbox number information is searched for, and the start address is referenced to find out where in the message data area the message is stored.

FIGS. 3 to 6 are flowcharts of message recording and reproduction operations of the cordless telephone apparatus according to this embodiment, and operation flowcharts of the master unit and the slave unit when a message reproduction request is issued from the slave unit.

First, the general operation of the answering machine function of the master unit will be described with reference to the flowchart of FIG.
In FIG. 3, when the bell signal is input a predetermined number of times, the master answering machine automatically answers and connects the telephone line 1 (step # 1). In order to send the response message common to all users (mailbox number 0), the mailbox designation means 14 designates the response message of the mailbox number 0, and searches by the message information in the message management area of the voice data storage unit 9. , The voice compression data stored in the message data area is extracted from the start address information (step # 2), and the voice data compression / decompression circuit 8
Is expanded (step # 3), converted into an analog signal by the analog / digital conversion circuit 7 (step # 4), and the voice recording / reproducing amplifier 6 transmits the voice from the telephone line 1 to the caller (step # 5). .

The common reply message has a content that prompts the DTMF signal to select the other party who normally leaves the message message. A mailbox number is designated by the mailbox designating means 14 by the DTMF signal inputted. If the other party to leave the message message is not designated, 0 is designated and stored as the common message message as a common message (step # 6).

At this time, the voice input from the telephone line 1 is captured by the voice recording / reproducing amplifier 6 (step # 7), converted into a digital signal by the analog / digital conversion circuit 7 (step # 8), and the voice data is compressed / decompressed. The voice data compressed by the circuit 8 (step # 9) is stored in the voice data storage unit 9 together with the compressed voice data, the start address of the message data area for storing the data, the mailbox number 0, and the message message (step # 9). #
10).

When the DTMF signal for designating the mailbox 2 is input during the transmission of the common reply message (step # 11), the mailbox designating means 14 designates the mailbox number as 2, and the designated mailbox is designated. Is retrieved from the voice data storage unit 9 (step # 12), and is sent to the telephone line 1 by the same procedure (steps # 3 to 5) as the common reply message is sent (step # 13).

After sending the response message, the voice data input from the telephone line 1 is stored in the voice data storage unit 9 as a message message of the mailbox number 2 in the same procedure (steps # 7 to 10). (Step # 14). When the recording of the message is completed, the telephone line 1 is automatically opened (step # 15).

Next, the reproduction operation of the message message will be described with reference to FIG.
Will be described with reference to. In FIG. 4, the message message may be sent to the telephone line 1, the wireless transmission / reception unit 3, the speaker 12, or the like, but the case of sending it to the speaker 12 will be taken as an example.

When the mailbox 2 is selected by the button operation from the operation unit 10, the mailbox designating means 14
Specifies mailbox number 2 (step # 1
6). The designated mailbox number is displayed on the display unit 11 by a liquid crystal display or LED so as to be clear (step # 17). If the mailbox number is not specified, the state is usually common (mailbox number 0) (step # 18).

When a message message reproduction request is issued from the operation unit 10, a message message of the mailbox number designated by the message information in the message management area of the voice data storage unit 9 is searched, and the start address information is transferred to the message data area. The stored audio compressed data is sequentially taken out (step # 19), expanded by the audio data compression / expansion circuit 8 (step # 20), and converted into an analog signal by the analog / digital conversion circuit 7 (step # 2).
1), the voice is transmitted to the speaker 12 through the voice recording / reproducing amplifier 6 (step # 22).

Next, referring to FIG. 5 for the master unit and FIG. 6 for the slave unit, the respective operations when listening to only the message message of a specific mailbox from the slave unit will be described. Let us explain alternately.

When an operation request for the answering machine function of the master unit is issued from the operation unit 21 on the slave unit side, an operation request code, which is a communication control signal from the control unit 17, is converted into a required frequency for transmitting to the master unit. Wireless transmission / reception unit 15
The data is transmitted to the parent device (step # 23). The master side performs demodulation processing for demodulating the high frequency radio wave signal from the slave and receives the operation request code, which is a communication control signal, by the wireless transmission / reception circuit 3 (step # 24).

If the master unit is in an operable state, a modulation process for converting the operation permission code into a required frequency for transmitting to the slave unit side is performed, and the wireless transmission / reception unit 3 transmits the code to the slave unit (step # 25). If it is not in the operable state, an error code is transmitted to the child device (step # 26). The slave unit waits until it receives the operable code within a fixed time after transmitting the operation request code (step # 27), and when receiving it, transmits a confirmation code notifying the master unit that the operable code has been received ( Step # 28). When the parent device receives the confirmation code from the child device (step # 29) within a fixed time after transmitting the operation permission code (step # 29), it enters the operation code receivable state (step # 30).

As described above, when the slave unit operates the master unit, the slave unit transmits the operation request signal, the master unit receives the signal, and then transmits the permission signal, and the slave unit receives the signal. After that, transmission and reception of one type of data is completed in the order of transmitting a confirmation signal. However, if the next data is not transmitted within a certain period of time while waiting for the reception of the next data, the operation request signal transmitted first becomes invalid.

Next, when the mailbox is designated by the dial key of the operation unit 20 of the slave unit, the slave unit transmits the mailbox number designation code (step # 31).
When the master unit receives this signal, it transmits the mailbox designation permission code (step # 32), and when the slave unit receives this signal, it transmits the confirmation code (step # 33). Here, the designation of the mailbox is completed by the mailbox designating means 14, and the designated mailbox is displayed on the display unit 22 of the child device by the liquid crystal or the LED so as to be clear.

If the mailbox number is not specified,
Normally, the common (mailbox number 0) message message is in a audible state. When a message message reproduction request is issued from the operation unit 21 of the child device, a message message reproduction request code is transmitted to the parent device (step # 34). Upon receiving this signal, the parent machine transmits a reproduction permission code (step # 35). When the handset receives this signal, it sends a confirmation code (step # 36). At this point, the master unit starts the reproduction operation.

The message data of the mailbox number designated by the message information in the message management area of the voice data storage unit 9 is searched, and the voice compression data stored in the message data area is sequentially extracted from the start address information. It is expanded by the compression / expansion circuit 8, converted into an analog signal by the analog / digital conversion circuit 7, sent out to the wireless transmission / reception section 3 through the audio recording / reproducing amplifier 6, and the audio data is converted into the required frequency for modulation processing. And transmits it to the child device (step # 37).

The handset receives this voice signal, performs demodulation processing to demodulate the high frequency radio wave signal, and outputs the reproduced sound of the message message to the speaker 18 (step # 38). When the reproduction operation of the message is completed, the parent machine transmits the operation completion code (step # 39). The child device receives this signal and ends the message message receiving operation (step # 40).

By the above operation, even a child device located in a place away from the parent device can select and listen only to a message message for personal use in the mailbox. In the above-described embodiment, the mailbox numbers designated by the mailbox designating means 14 are displayed on the display units 11 and 22 respectively provided in the master unit and the slave unit, so that the mailbox numbers can be used as the master unit and the slave unit. Although it can be confirmed on both machines, a message designating means is provided in the control unit 5, and in the same display unit 11 and 22, in order to confirm the message recording area designated by the message designating means, in the mailbox. The message data area in which the message is recorded can also be displayed.
