Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION This invention relates to telephones and wireless telephones.

[0002]

2. Description of the Related Art Telephones that have a keyboard such as a dial on the telephone body and have an external handset installed away from the telephone body to make a call with the other party at the user's hand have been widely known. Has been.

[0003]

However, in the above-mentioned conventional telephone, since the key for making and receiving the call is provided in the telephone body, the user moves to the telephone body and operates the keyboard when the operation for making and receiving the call and the end of the call are made. Therefore, there is a problem that the advantage of having an external handset cannot be fully enjoyed even during hands-free communication using a headset or the like.

The present invention solves the above problems and provides a telephone with a remote control for making and receiving calls, which has a simple structure and is capable of handing incoming and outgoing calls and ending calls without using a special signal line. The purpose is to

[0005]

In order to achieve the above object, the present invention provides remote control operation means for issuing an operation signal for making and receiving a call or ending a call between a telephone body and an external handset.
In the main body of the telephone, there is provided a detecting means for making the main body control incoming and outgoing in response to the operation signal.

Further, the transmission / reception means and the remote control operation means, and the remote control operation means and the detection means are connected by a normal transmission voice line.

[0007]

Therefore, according to the present invention, by operating the remote control operating means at the user's hand, the user can answer an incoming call, make a call to a specific party, and end a call without moving to the main body of the telephone. Has the effect.

Further, since the remote control operating means and the detecting means are connected by the conventional transmission system audio line,
There is an effect that the operation of making and receiving a call and ending the call can be performed without requiring a special signal line and without making any change to the external handset.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 is a telephone body connected to a line by wire or wirelessly, and is provided with a control unit 1a for controlling incoming and outgoing calls and the like, and a keyboard 1b such as a dial.
2 is a detection unit which is a detection means provided in the telephone body,
Reference numeral 3 is a remote control switch box as remote control operation means for issuing an operation signal in response to an operation, and reference numeral 4 is an external handset for making a hands-free call using a headset or the like. Reference numeral 5 is a voice transmission system voice line that connects among the detection unit 2, the remote control switch box 3, and the external handset 4.

Next, the operation of the above embodiment will be described. In FIG. 1, when the switch box 3 for remote control is operated, an operation signal is emitted, and the detection unit 3 detects that the operation signal is operated. By this detection, the control unit 1a is instructed, and after a certain time, the telephone main body 1 performs an incoming call response in the case of an incoming call, and an operation of calling to a specific partner in the standby state. After that, the voice system is operated, and the user can make a hands-free call using the external handset. When the call ends, the detection unit 2 detects it by operating the remote control switch box 3 again, and the control unit 1a of the telephone body 1 controls the operation for ending the call.

In this case, the user can make an incoming and outgoing call and end the call by operating the remote control switch box 3 at hand, without operating the telephone body 1.

FIG. 2 shows the circuits of the detector 2 and the switch box 3 for remote control. During normal operation when the switch 3a of the remote control switch box 3 is not pressed,
The transmission voice line 5 is at a high level, the transistors Q1 and Q2 are both in the ON state, and "L" is input to the control unit 1a of the telephone body 1. When the switch 3a is pressed down, the transmitting voice line 5 becomes low level, the transistor Q1 is turned off by the voltage division of the resistors R1 and R2, and the transistor Q2 is also turned off.
"H" as a command signal is input to the control unit 1a.
In response to this command signal "H", the telephone body 1 performs operations for making and receiving a call and ending a call to the other party.

As described above, the procedure for making and receiving a call and terminating a call is performed by the remote control switch box at the user's hand without making any changes to the conventional external handset and using a special leased line. Can be done.

[0014]

As is apparent from the above embodiments, in the telephone with a remote control for making and receiving calls according to the present invention, remote control operation for issuing an operation signal for making and receiving a call or ending a call between the telephone body and the external handset. Means and a detecting means for controlling the incoming and outgoing call to the main body in response to the operation signal in the main body of the telephone, thereby operating the remote control operating means at the user's hand to move to the main body of the telephone. In addition, it has an effect of being able to answer an incoming call, make a call to a specific partner, and end a call.

Furthermore, since the remote control operating means and the detecting means are connected by a conventional transmission system audio line,
There is an effect that the operation of making and receiving a call and ending the call can be performed without requiring a special signal line and without making any change to the external handset.
