Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone with a long telephone notification function, and more particularly to a telephone with a long telephone notification function having a call confirmation function.

[0002]

2. Description of the Related Art A conventional telephone has an incoming circuit, a dial circuit, a hook switch, a call circuit, and a handset.

[0004]

The conventional telephone is for making a call, and it is the intention of the caller to terminate the call. In that case, there was a problem that the call charge of the phone would be high.

An object of the present invention is to provide a telephone having a function of preventing an excessive long call.

[0006]

In order to achieve the above object, in a telephone with a long telephone notification function according to the present invention, a call confirmation circuit for detecting whether a telephone line is connected or disconnected, It has an elapsed time notification circuit for notifying the elapsed time by voice every time a certain time has elapsed since the start of the call.

[0007]

[Operation] It is confirmed that the telephone is in a call, and the elapsed time by voice is notified each time a certain time has elapsed from the start of the call.

[0008]

The present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of the present invention.

In FIG. 1, the telephone according to the present embodiment is
In addition to the call receiving circuit 1, the dial circuit 2, the hook switch 3, the call circuit 4, and the handset 5 which are the functions of a normal telephone, a call confirmation circuit 6 that detects the start and end of a call and a call from the start of the call It has an elapsed time notification circuit 7 that periodically notifies the elapsed time until the end.

FIG. 2 shows a call example.
