The operation of the conventional device configured as described above will be described below.

When a call is made from outside, a calling signal is received from the telephone line 15, the calling signal is modulated by the transmitter 17 from the ringer circuit 16, and is radiated as radio waves to the mobile unit 1 through the filter 18 and antenna 4. The radio wave is demodulated by the antenna 2, the filter section 36, and the receiving section 37, and is amplified by the power amplifier 41 to cause the speaker 42 to sound. When the wearer moves the switch 40 from the standby position B to the call position A, the microphone amplifier 34 and the transmitter 35 are turned on and a call is possible.The words of the wearer are amplified from the microphone 33 by the microphone amplifier 34 and transmitted. The signal is modulated by the section 35 and radiated as a radio wave through the filter 36 and the antenna 2. The radio wave is received by the antenna 4 of the main unit 3, passes through the filter unit 18, is demodulated by the receiver unit 19, and is transmitted through the network 20 to the telephone line 1.
5 and exchange with the line is performed.

Note that when the switch 40 is set to the talking state a, a signal is sent from the control section 38, and the signal that passes through the transmitting section 35, filter section 36, antennas 2, 4, filter section 18 and receiving section 19 is sent to the control section 21 in the same way as above. Turn on the input network 20.

If you want to record the content of the conversation at this time, you can go near the main unit 3 and operate the recording switch 32, or a secretary, for example, who is near the main unit, can press the switch 28.
The power amplifier 26 operates the line and received signals.
The conversation is monitored through a speaker 27, and depending on the content, the secretary operates a recording switch 31 to record the content of the conversation. The main body 3 itself has a microphone 23 and a microphone amplifier 24, and recording can be made by operating a recording switch during non-calling.

However, in the above-mentioned conventional configuration, since the magnetic recording and reproducing device 5 is located in the main body 3, there is a problem that recording cannot be performed when the mobile unit is away, that is, conversation recording and memo recording cannot be performed. . Also, when there was no one at the main unit, it was not possible to record the contents of a call with an outsider or to record and prepare the contents of a message.

Purpose of the invention The present invention solves the above-mentioned conventional problems.
To provide a telephone with a wireless recording function capable of not only recording conversations and memos but also transmitting recorded contents through a line.

Structure of the Invention The present invention is a wireless recording telephone equipped with a recording/playback device and a transmitting signal/playback signal switching switch in a portable unit, and by switching the switch, the transmitting signal and the tape playback signal can be switched. It is characterized by being supplied to telephone lines via radio.

The operation of the wireless recording function telephone of this embodiment constructed as described above will be explained below.
First, when a call is received from the line, the ringer circuit 81 of the main body section 47 operates, the ringing tone is modulated by the transmitting section 82, and a radio signal is sent out through the filter section 83 and the antenna 84. The filter section 74 selects only the desired frequency of the signal input to the antenna 56 of the mobile section 43, and the calling signal demodulated at the receiving section 72 passes through the switch 62 and the power amplifier 63 to drive the speaker 64 and transmit the signal to the user. call.
When the wearer changes the switch 88 from the standby state b to the talk state a, a signal is emitted from the control section 63, and the signal modulated by the transmitting section 71 is emitted as radio waves through the filter section 74 and the antenna 56. From the signal received by the antenna 84 of the main body section 47, only a desired frequency is selected by the filter section 83, demodulated by the receiving section 85, and sent to the control section 79.
Enter. The control unit 79 confirms that the power is on, and connects the line of the network 78 with a relay or the like to connect with the line 75, and a call state is established. The user receives the sound from the portable unit 43 through the microphone 59 as an electrical signal through the microphone amplifier 60, the switch 61, the transmitting unit 71, and the receiving unit 8 of the main unit 47 in the same way as above.
5 to the network 78 and line 75, and a conversation is established. When it is desired to record a memo of the contents of the call, the switch 69 is activated, which activates the recording circuit and records it on tape.

When the carrier wants to make a call outside, switch 8
When 8 is set to talk state a, the main body 4
7 network 78 is connected to line 75.
In this state, if a dial signal is sent from the dial unit 70, a connection is established with the other party. Switch 61 during a call
It is possible to automatically send out the tape playback output and the contents of the message by switching the . Also, by pressing the call button * on the dial section 70, the main body section 47 is called from the mobile section 43, and the switch 61 is switched in the same way as above to transmit the tape recording contents. If the volume from the side 47 increases and the other party speaks through the transmitter when the tape ends, the user can be contacted with a sufficiently loud sound.

As described above, according to this embodiment, by providing a switch for switching between the cassette playback output and the microphone output on the portable unit, it is possible not only to easily record memos during a call, but also to be able to easily record the contents of the message. It can be easily communicated to the other party, and the above functions can be performed by adding a single switch, so high added value can be obtained at low cost. At the same time, since the volume of calls from the main body increases, calls from the main body can be recognized even when the mobile unit is separated.

In this embodiment, the recording and reproducing device is a microcassette recorder, but the recording and reproducing device may also be an IC memory. Also, although the content of the tape recording was used as the message to be communicated, music can also be played while the other party is waiting for a call.

Effects of the Invention The present invention provides a mobile unit of a wireless recording telephone with
Equipped with a recording/playback device and a selector switch between its playback output and talking section, it has an excellent wireless recording function that allows you to not only record the contents of a call, but also easily transmit the contents of a pre-recorded message. It is possible to realize a telephone.
In addition, by providing a volume switch in the speaker unit that is linked to the tape, you can monitor the content of the transmission without holding the mobile unit to your ear, and when the tape ends, you can hear the caller's voice, making effective use of the time in between. This makes it possible to realize a telephone with an excellent wireless recording function.
