And improve usability.

(Prior Art) In a cordless telephone device of this type generally used, when an incoming signal is transmitted from a telephone line, the parent device transmits the incoming signal to the child device, and the parent device and all the child devices are simultaneously transmitted. A ringing tone is generated.

Then, the owner can take a master unit or a slave unit at the nearest position and operate a call button to talk with the caller via the master unit.

(Problems to be Solved by the Invention) However, in the above-described conventional device, the ringing sounds of the parent device and the plurality of child devices ring simultaneously at the time of an incoming call. It was not clear until the call was answered, and a call to another person had to be forwarded or called, which was inconvenient.

(Means for Solving the Problems) An object of the present invention is to eliminate the drawbacks of the above-mentioned conventional device, and to provide a cordless device comprising a master unit connected to a telephone line and a slave unit wirelessly connected to the master unit. A determining means for determining a terminal performing a call notification based on an identification code sent from a telephone line; and a call notification terminal for notifying an incoming call based on a result of the determination by the determining means. And control means for causing a terminal other than the call notification terminal to make a notification different from the call notification.

(Operation) Therefore, according to the present invention, when the identification code is sent from the caller at the time of the incoming call, the judging means judges the terminal which performs the call notification based on the identification code, and the control means judges the judgment result. On the basis of the call notification terminal to perform a call notification to notify the incoming call, and by performing a notification different from the call notification in a terminal other than the call notification terminal,
Based on the identification code sent from the caller at the time of the incoming call, only the base unit or a specific handset can sound a ringing sound, and in a device that does not sound a ringing sound, the base unit or a specified handset. Can be notified that a call has been made.

Hereinafter, the present invention will be described in detail with reference to an embodiment shown in the drawings.

And a line capturing circuit 12 for controlling the hook switch 3.
And switches consisting of dial keys and various function keys
13 and a control unit 14 for controlling each of the above units.

The control unit 14 includes a response unit 141 that controls the line capturing circuit 12 based on a signal from the incoming call detection circuit 11, and a switch group 1
A switch group control unit 142 for detecting whether or not a key provided in the switch unit 3 is operated; and an RA for storing a state of a function set based on an output from the switch group control unit 142 and the like.
M143, determining means 144 for determining the identification code sent from the caller, and control means 145 for controlling the transmitting unit 8 and the receiving unit 9 based on the signal from the determining means 144 are provided.

On the other hand, as shown in FIG. 2, a transmission unit 15 and a reception unit 16 for connecting a wireless line to the base unit 1, an antenna 17 and a separation of an audio signal are provided to the slave units 7a and 7b. An audio circuit 18 for mixing and the like, a microphone 19 and a speaker for making a call
20, a control unit 21 for identifying the identification code sent from the base unit 1 and controlling each unit, and a buzzer 22 for generating a ringing tone
Is provided.

Next, the operation of the cordless telephone device configured as described above will be described.

First, the operation in the case of a normal incoming call will be described.
When an incoming signal arrives from the telephone line 1, an incoming detection circuit 11
And a signal is output to the response means 141. The response means 141 determines whether or not the selective calling function is set in the RAM.
The signal is read from 143, and if not set, a signal is output to the control means 145, a ringing tone is generated from the speaker 6 via the audio circuit 4, and a predetermined signal is transmitted from the antenna 10 via the transmitting unit 8.

On the other hand, in the slave units 7a and 7b, the signal transmitted from the master unit 1 is received by the receiving unit 16 via the antenna 17, and the identification code is not included in the signal received by the control unit 21 in the next stage. When detected, the buzzer 22 is driven to generate a ringing tone.

Then, when the owner picks up the handset of the base unit 2 in response to the ringing tone, the microphone 5 and the speaker 6 can talk with the caller via the audio circuit 4. Further, when one of the plurality of slaves 7a and 7b is picked up and a predetermined operation is performed, a wireless line is connected to the master 2 and a call can be made with the caller through the microphone 19 and the speaker 20. You can do it.

Next, the operation when the selective calling function is set will be described. To set the selective calling function, the user operates a selective calling key in a switch group 13 provided in the base unit 2.
By doing so, the switch group control means 142 detects the setting and the setting of the selective calling function is stored in the RAM 143.

Thereafter, when an incoming signal arrives from the telephone line 1, the incoming signal is detected by the incoming detection circuit 11 and is output to the response means 141. The response means 141 reads from the RAM 143 whether or not the selective calling function is set, and if so, closes the hook switch 3 via the line capturing circuit 12. Then, when the identification code is sent from the telephone line 1, it is inputted to the judging means 144, and the judging means 144 judges whether or not the identification code is its own identification code stored in the RAM 143. A ringing tone is generated from the speaker 6 via the audio circuit 4 by the means 145. Also, the judgment means 144
When the identification code determined in step (1) is the identification code of the slave units 7a and 7b, the control unit 145 transmits a predetermined signal including the identification code from the antenna 10 via the transmission unit 8.

On the other hand, in the slave units 7a and 7b, the signal transmitted from the master unit 2 is received by the receiving unit 16 via the antenna 17, and the identification code included in the signal received by the next-stage control unit 21 is determined. Then, the slave unit 7a that has determined that the identification code is its own identification code drives the buzzer 22 to generate a ringing tone. In the slave unit 7b that determines that the identification code is not its own identification code, the control unit 21 drives a lamp (not shown) to notify that the master unit or another slave unit is in use. At the same time, the audio circuit 18 is muted and cannot be used.

Therefore, in the cordless telephone device according to the above-described embodiment, when a plurality of slave units 7a and 7b are provided so as to correspond to a family or the like, only the slave unit 7a or 7b of the other party to be called can be called, so that the usability is improved. It can be significantly improved.

In the above embodiment, the hook switch 3 is simply closed when an incoming call is received. However, the answering machine telephone function may be provided in the base unit 2 to transmit a response message or the like. When the identification codes received by the slave units 7a and 7b are different, the audio circuit 18 is muted. However, the operations of the transmission unit 15 and the reception unit 16 may be stopped.

(Effects) As described above, according to the present invention, only the parent device or a specific child device can ring the ringing tone based on the identification code sent from the caller at the time of the incoming call. There is no need to transfer or call when a call comes to a person, thereby improving usability. In a device that does not sound a ringing tone, a master unit or a specific slave unit is called. Is notified, it is possible to prevent a device other than the called parent device or a specific child device from receiving an incoming call accidentally or from erroneously recognizing that the device has failed. it can.
