Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cordless telephone, and more particularly to a cordless telephone capable of simultaneously sending voice messages to a plurality of handsets.

[0002]

2. Description of the Related Art In cordless telephones, there are cases where it is desired to simultaneously send a voice message from a master unit to a plurality of slave units and simultaneously transmit the same information from the master unit to all the slave units.

As the information transmission means, call originating data is separately sent from a base unit of a cordless telephone to a plurality of handset units, and voice messages are sent all at once after receiving a response from the handset unit. That is, calling data is sent from the parent device to the child device, and the parent device waits for a response signal from the child device.

Next, the master unit sends call data to another slave unit, and the master unit waits for a response signal from the slave unit.

In this manner, the calling data is sequentially sent to the plurality of slaves, and the master waits for a response to the calling data.

When there is a response of the calling data from the child device to the parent device, except for this child device, the calling data is sent again to all the child devices that have not received the response of the calling data, and Wait for a response from the child device. When the call data is sent and responded, if there is a call data response from all the handset units, the sending operation is completed at that point, and if there is no call data response from all the handset units. To improve the efficiency of time, it will be terminated at a predetermined time.

After the calling / answering operation is completed, the general call switch of the master unit is operated, and a channel designating signal is sent from the arithmetic unit such as the CPU to the slave unit to which the calling data is responded. Upon receiving this channel designation signal, the child device designates a channel and sends the completion signal to the parent device.

At the stage where such an operation is completed, a communication path is set and a voice message is sent out.

Therefore, there is a problem that it takes several seconds from the calling of all the slaves to the sending of the voice message.

In order to eliminate such drawbacks, the present invention provides a cordless telephone which automatically performs a process from calling a handset to sending a voice message.

[0011]

According to the present invention, in a cordless telephone having a master unit and a plurality of slave units, a recording unit for recording a voice message and a plurality of slave units for recording the voice message recorded in the recording unit. (EN) A cordless telephone characterized in that a master unit is provided with a sending section for sending all at once.

Further, in a cordless telephone having a master unit and a plurality of cordless handsets, call data is sent to the plurality of cordless handsets in order and a call data transmission is sequentially received from the plurality of cordless handsets. Section and the calling data transmission section have detected the calling data response from all the slaves,
Alternatively, the master unit includes a voice sending unit that sends a voice message recorded simultaneously to a plurality of slave units when a predetermined time has elapsed from the start of calling data transmission before receiving responses from all slave units. There is provided a cordless telephone characterized in that

[0013]

[Function] The voice message recorded in the recording unit of the master unit is sent to a plurality of slave units and the slave units are simultaneously called.

Also, the voice message recorded in the recording unit of the master unit is sequentially sent to a plurality of slave units, and after the master unit detects the response of the calling data from the slave unit or after a predetermined time elapses, the slave units are simultaneously broadcast. Send a voice message. As a result, the voice message is automatically transmitted from the master unit to the slave unit.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the cordless telephone of the present invention will be described below with reference to the accompanying drawings.

The base unit 31 of the cordless telephone 30 of the present invention shown in FIG. 1 is provided with a microphone 13, a compander 15, a baseband modem 16 and a radio unit 17. A voice recording / reproducing unit 33 having a storage device 32 such as a DRAM is connected between the microphone 13 and the compander 15, and the baseband modem 16 has arithmetic control of a CPU or the like having a calling data transmitting unit built-in. The part 34 is connected. The arithmetic control unit 34 is provided with the simultaneous call switch 18 and the timer 35.

The slaves 12a, 12b, ..., Which receive radio waves from the radio unit 17 of the master 31, are the same as the conventional slaves, and the radio units 20a, 20b ,.
Receiving radio waves, the baseband modems 21a, 21b,
, To convert the wireless telephone into a voice signal, and the compander speaker up 22a, 22b, ... to amplify the voice signal,
Speakers 23a, 23b, ...
The message to receive the first prize is received as voice.

The operation of the cordless telephone 30 having such a configuration will be described with reference to the response sequence shown in FIG.

First, the storage device 32 stores the voice message from the microphone 13 via the voice recording / playback unit 33 (S
1) Then, the timer 35 is set and the operating time is determined.

After the above operation is completed, the timer 35
, Or when a paging is required, the paging switch 18 is closed. As a result, the calling data transmission section of the arithmetic control section 34 is activated, and the slave units 12a, 12
b, 12c, ..., 12n are simultaneously called (S
2).

In this paging, the calling data is sent from the calling data sending section of the base unit 31 to the handset 12a, and the handset 12 is called.
Wait for a response of the calling data from a, and after a predetermined time, the base unit 3
The call data transmission unit 1 transmits the call data to the slave unit 12b, waits for a response of the call data from the slave unit 12b, and then the call data transmission unit of the master unit 31 issues the call data to the slave unit 12n. The call data is transmitted and the response of the call data from the slave unit 12n is waited for.

During this time, for example, when the response of the slave unit 12b is not obtained, the call data transmission unit of the master unit 31 transmits the call data to the slave unit 12b, and the call data from the slave unit 12b is transmitted. The system waits for a response, and several calls are made until a response from the child device 12b is obtained.

After the responses have been obtained from all the slaves or after a predetermined time has elapsed, a channel designating signal is sent from the master 11 to the slaves that have received a response from the arithmetic and control unit 34. When the slave unit receives the channel designation signal, it is switched to this channel. In this switching, when the switching of the last slave unit, for example, slave unit n is completed, a switching completion signal is sent to the master unit 11. After this channel switching, the audio circuits of the slaves 12a, 12b, 12c, ..., 12n are formed.

Upon completion of such a response operation, the arithmetic control unit 34 sends a voice message sending signal to the voice recording / playback unit 33. When the voice recording / playback unit 33 receives this transmission signal, the voice recording / playback unit 33 reads the voice message stored in the storage device 32, plays back the voice message, and sends a response via the compander 15, the baseband modem 16, and the wireless unit 17. The slaves 12a, 12b, 12c, ...
12n speakers 22a, 22b, 22c, ..., 22n
Are automatically sent all at once (S3).

As a result, the base unit 31 automatically makes a call to all the handset units, and voice messages are simultaneously sent to the handset units.

Note that, when a call is made to all the slaves at a predetermined time every day, it can be automatically made by setting the timer 35.

[0027]

In the cordless telephone of the present invention, the master unit sequentially makes a call to a plurality of slave units and simultaneously sends the voice messages. Therefore, the simultaneous sending of the voice messages is automatically performed by a simple call operation. I can do it.
