Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a cordless telephone, and more particularly to a cordless telephone in which an answering machine function unit is placed in a standby state when a portable unit having a wireless unit is separated.

[0002]

2. Description of the Related Art Generally, a cordless telephone has a call function section, an answering machine function section,
The main unit includes a control unit and a wireless unit, and the mobile unit includes a call function unit and a wireless unit and is movable.

Since a call between the base unit and the handset of this cordless telephone is performed by radio waves, the handset is moved far away from the base unit or the handset moves to a place where radio waves of the base unit are out of reach. When this happens, there is a problem that the call between the child device and the parent device cannot be performed.

Therefore, when the slave unit is far away from the master unit and cannot communicate, the radio unit of the master unit is separated from the master unit so that the radio unit of the master unit and the slave unit can communicate with each other. There is.

However, in such a case, even if the base unit receives an incoming call from an outside line, the incoming call is not recorded and the function as a cordless telephone is impaired unless the answering machine is in a standby state.

Therefore, the present invention can be used as an ordinary cordless telephone before separating the radio unit of the master unit, and after separating the radio unit of the master unit, the call between the radio unit of the master unit and the slave unit can be performed. (EN) Provided is a base unit of a cordless telephone set in a standby state so that an incoming call to the base unit from an outside line can be recorded in an answering machine function unit.

[0007]

SUMMARY OF THE INVENTION The present invention comprises at least one
In a cordless telephone equipped with two cordless handsets and a cordless handset capable of communicating with this cordless handset via a free line,
At least a call function unit, an answering machine function unit, a base unit having a control unit, a portable unit detachably connected to the base unit and having at least a wireless unit and a wireless control unit, and the portable unit and the base unit are separated. At this time, there is provided a cordless telephone characterized by comprising an answering machine operation standby function section for detecting the separation state of the portable section and the base section and putting the answering machine function section in a standby state.

[0008]

[Function] When the slave unit is far away from the master unit or when the radio waves of the master unit or the slave unit cannot be transmitted to each other, the radio unit of the master unit is separated and a call is made between the radio unit and the slave unit. Let

When the wireless unit is separated, the separated state is detected, and the answering machine function unit of the master unit is set in the standby state so that the incoming call from the outside line can be recorded.

The operation of the cordless telephone having such a structure will be described with reference to FIG.

First, a case where the base unit 10 receives a call signal from an outside line and transmits the call signal to the handset unit 50 in a normal state in which the portable unit P is connected to the base unit B of the base unit 10 will be described.

In advance, an available empty channel is detected by exchanging information between the channel detection unit 35 of the wireless control unit 26 of the base unit 10 and the empty channel memory unit 38, and this empty channel is notified to the wireless unit 15. It is stored in the empty channel memory unit 38.

When the base unit 10 receives an incoming signal from an outside line in such a state, the incoming signal is detected by the bell detecting section 12. The incoming signal is sent to the control unit 18, the telephone function unit 12, the first signal switching unit 16, the wireless control unit 26.
Etc. and controls the wireless unit 15 of the base unit 10 to the handset 5
An empty channel is designated and transmitted to the radio unit 52 of 0.

When the slave unit 50 responds to the incoming signal, the channels of the master unit 10 and the slave unit 50 are switched to the designated channel. When the channel is switched, a bell ringing signal is sent from the wireless unit 15 of the master device 10 to the slave device 50. When the off-hook signal is received from the handset device 50, the connection with the outside line is established via the outside line connection terminals 11a and 11b, and the telephone call between the base unit 10 and the handset device 50 is performed.

Next, the case where the slave unit 50 is far away from the master unit 10 and the radio wave from the master unit 10 is not transmitted to the slave unit 50 will be described.

In such a case, the base unit B including the telephone function unit 12, the answering machine function unit 17, the control unit, etc. of the base unit 10.
The wireless unit 15, the wireless control unit 26, the portable unit P including the charging detection unit 27, and the like are separated by the connector 23, and the portable unit P serves as a wireless handset that can move independently.

When the base unit 10 is separated, the base portion B
Then, the separation detector 21 detects this separation state and sends the output signal to the controller 18. The control unit 18 sends the control signal to the first signal switching unit 16, connects the telephone function unit 12 and the first handset unit 14, sends the control signal to the answering machine function unit 17, and receives the incoming call signal from the outside line. The function unit 17 is set to a standby state so as to record. In addition, in the portable unit P, the charging detection unit 27 detects this separation state, and outputs the output signal from the wireless control unit 2.
Send to 6. The wireless control unit 26 sends the control signal to the second control signal.
The signal is sent to the signal switching unit 25 to connect the second handset unit 24 and the wireless unit 15, and the control signal thereof is sent to the wireless unit 15.
And set so that the call with the handset 50 can be made.

When the base section B is separated in this way, the call function section 12 and the first handset section 15 are connected to enable a call, and the answering machine function section 17 is put in a standby state to always receive an incoming signal from an outside line. It is possible to make a recording, and the portable unit P can independently talk with the handset 50.
