Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing a first embodiment of the present invention.

A telephone 1 with a voice recording function according to the present invention records a telephone circuit 3 having a basic function of transmitting and receiving voice signals via a telephone line 2 and a voice signal transmitted and received via the telephone line 2. And a recording device 4 for receiving signals at the time of external remote control, a push-button signal receiver (hereinafter referred to as a PB receiver) 5, a voice synthesizing circuit 6 for response, and And a control unit 7 for controlling the device and the circuit. The recording device 4 includes a changeover switch 8 and recording devices 9 and 10 capable of recording for a long time as shown in the block diagram of the recording device in FIG. Recording device 9 with a period of a fixed time,
10 is started and stopped, and recording is performed alternately. The telephone circuit unit 3 has a recording button 1 for instructing the start of recording.
1 and a playback button 1 for instructing playback of the recorded audio signal
2 is included.

Next, the operation will be described. Figure 1 for explanation
3 to FIG. 3, and FIG. 1 and FIG. 2 are used as names and reference numerals.

FIG. 3 shows a recording / reproducing device 9, 1 in the recording device 4.
FIG. 9 is an explanatory diagram illustrating an operation state of 0. When the user of the telephone with a voice recording function of the present invention starts a telephone call using the telephone, a control signal for starting the telephone call is output from the control unit 7, and the recording / reproducing device 9 is activated to enter the recording state (a). . In this state, when a predetermined time T has elapsed, a switching control signal is output and the recording / reproducing device 9 is stopped, and at the same time, the recording / reproducing device 10 is activated to be in the recording state (b). This time length T is arbitrarily determined, but is usually set to an arbitrary value between several seconds and several tens of seconds. Further, after a lapse of a certain time T, a switching control signal is output from the control unit 7, the recording / reproducing device 10 is stopped, and at the same time, the recording / reproducing device 9 is activated again to set the recording state (c). At this time, the recording / reproducing device 9 sets the recording location as the location used in the previous recording state (a), and performs recording in a manner superimposed on the previous recording. In this state, if the telephone user wants to record the voice during the call, the record button 11
Press. The control unit 7 having received the press signal of the recording button 11 will thereafter operate the recording / reproducing device 9 until the end of the recording or the end of the call.
In the recording state (c). This is because the recording button 1 can be pressed at any time when the recording / reproducing device 10 is in the recording state (b).
Similarly, when the button 1 is pressed, the recording / reproducing apparatus 10 is kept in the recording state (b) even after the predetermined time T has elapsed.

Next, when playing back the recorded call, when the user of the telephone presses the play button 12, the control unit 7
Indicates that the recording button 11 has been pressed when the recording / reproducing apparatus 9 is in the recording state (c) from the remaining record, and reproduces the recording portion of the recording / reproducing apparatus 10 first. Subsequently, the recording portion of the recording / reproducing device 9 is reproduced, so that the “recording state (b) for a certain period of time T” is started from the point in time when the recording button 11 is pressed, as shown in the section that can be heard during reproduction in FIG. In addition, it is possible to listen to the call voice from a past point in time for "a part of the recording state (c)". As a result, it is possible to secure "the fixed time T of the recording state (b)" at the shortest.

As described above, when a voice during a call is recorded, the call voice at least a predetermined time T before the recording button 11 is pressed can be heard.
Never miss an important call. Further, since it is easy to change the length of the fixed time, it can be set at any time according to the convenience of the telephone user.

Although not the object of the present invention, it is possible to use the recording device 4 to add the function of the answering machine. Further, it is possible to use the PB receiver 5 and the voice synthesizing circuit 6 to reproduce and listen to the call voice recorded in the recording device 4 by remote control.

In the above description, currently available devices and systems can be used as the recording / reproducing devices 9 and 10 of the recording device 4. Therefore, no particular configuration is described. It is proposed to use mini-discs as the recording and reproducing devices 9 and 10 in the telephone 1 with a recording function. The use of mini-discs as the recording / reproducing devices 9 and 10 enables recording for a longer period of time as compared with the case of using a recording / reproducing device using a magnetic tape which has been used for an answering machine. Even if only the point that makes it easy to access a specific part at the time of reproduction can be expected, a remarkable improvement can be expected.

[0019]

As described above, according to the present invention, the recording apparatus is constituted by two equivalent recording / reproducing apparatuses capable of recording for a long period of time, so that the delay time is longer than a few seconds. Even in the case of the order, there is an effect that it is economically inexpensive and technically easily realizable.
