Then, the respective metal contacts 37 on the lower surface of the mobile phone section and the upper surface of the answering machine section are connected, the mobile phone section is switched to the non-communication state, and the answering machine section enters the recording mode. At this time,
When the antenna 2 receives an incoming call from the relay station, an incoming signal is sent to the recording / playback control unit 6 via the receiving unit 4. When the incoming signal is received, the recording / playback control unit 6 puts the telephone line into a call state, and sends the response message recorded at the beginning of the magnetic tape 11 from the recording / playback amplifier 13 to the other party of the call through the sending unit 3 of the mobile phone unit. To do. After that, the magnetic tape 11 is cued up to a predetermined position by the motor control unit 7, and a single sound is output to inform the other party of the recording ready state.
0 is transferred to the recording state. At this time, the recording / reproduction control unit 6
The output port 25 is maintained in a state of a voltage higher than a predetermined specified voltage (hereinafter, referred to as HIGH state). Therefore,
When the input port 23 is in the HIGH state, the circuit used for recording by the recording / reproducing amplifier 13 becomes valid and the circuit used for reproducing becomes invalid. When the input port 23 is in the HIGH state, the oscillator circuit 15 oscillates to generate a sine wave. This sine wave is supplied to the erasing head 14 and a magnetic field is generated to erase the audio information recorded on the magnetic tape 11. The audio information output from the input / output port 24 of the recording / reproducing control unit 6 is transferred from the input / output port 21 to the recording / reproducing amplifier 13

The audio information reproduced by the recording / reproducing unit 10 is output to the transmitting unit 3 in the reproduction state of 0, and then the audio information received by the receiving unit 4 is output to the recording / reproducing unit 10 in the recording state of the recording / reproducing unit 10. is there.

Next, the reproduction of recorded contents will be described. First, the release button 3 in the direction of the arrow in FIG.
When 6 is moved, the movable stopper 34 slides at the same time,
The notch 33a provided in the fixed stopper 33 and the protruding portion 34b provided in the movable stopper 34 are aligned with each other. At this time, the mobile phone section and the answering machine section are separated by lowering the right side of the answering machine section in FIG. 1B in the direction opposite to the arrow. Then, the metal contacts 37 of the mobile phone section and the answering machine section are separated from each other, and the answering machine section enters the reproduction mode. At this time, when a reproducing operation is performed from the recording / reproducing operation unit 5, a signal is sent to the recording / reproducing control unit 6 to bring the recording / reproducing unit 10 into a reproducing state and cue the recorded message. At this time, the recording / reproduction control unit 6 holds the output port 25 at a voltage lower than a prescribed voltage (hereinafter, referred to as LOW state), so that the input port 23 becomes LOW state. As a result, the circuit used during reproduction of the recording / reproduction amplifier 13 becomes valid and the circuit used during recording becomes invalid. Further, since the input port 23 is in the LOW state, the oscillation circuit 15 does not perform the oscillating operation, so that the sine wave is not generated. Information from the magnetic tape 11 is taken in from the recording / reproducing head 12, amplified by the recording / reproducing amplifier 13, passed through the input / output port 21, and supplied to the recording / reproducing control unit 6 via the input / output port 24. Thereafter, the recorded content is output as sound from the recording / reproduction control unit 6 through the external jack 8 and the external earphone (not shown). When the user operates the recording / reproduction operation unit 5 to cancel the reproduction, the recording / reproduction control unit 6 cancels the reproduction state of the recording / reproduction unit 10.

When the recording / reproducing unit 5 is set to the normal mode, the answering machine does not cue a reply message, a recording message, etc., and recording / reproducing can be performed as a normal tape recorder. In this case, the mobile phone unit may be connected to the answering machine, and the transmitter unit 26 of the mobile phone unit may be used as a microphone and the receiver unit 27 as a speaker.

In this embodiment, a magnetic tape is used as a recording medium and the answering machine is a tape recorder. However, a rewritable recording medium such as an optical disk, a magnetic disk and a semiconductor memory is used, and a recording / reproducing apparatus corresponding to these is also used. It goes without saying that the same effect can be obtained.

Further, when reproducing the recorded contents of the answering machine, the receiving section 27 of the mobile phone may be used instead of the external jack 8 of the answering machine by connecting the portable phone section.

As described above, according to the present invention, even if the user of the mobile phone device cannot answer the incoming call due to a situation such as during a conference, the message from the other party can be sent by connecting the answering machine in advance. Can record.
