[Detailed description of the invention] The present invention relates to a receiver having a remote control function, and is capable of remote control according to the program of a controlled device such as a tape recorder without any special control line. .

Hereinafter, an embodiment of the receiver having a remote control function of the present invention will be described with reference to the drawings.

In the drawings, 1 generally indicates a receiver according to the invention. 2 indicates a plug to which commercial AC power of 50 Hz is supplied, for example, and the commercial AC power obtained from this plug 2 is used for radio reception via a connection switch 3 whose on/off is controlled by a control signal from a microcomputer 5 with a built-in timer, which will be described later. Supplies power to the main body 4 of the machine. This radio receiver main body 4 has a synthesizer receiver structure having, for example, a synthesizer tuner, etc., and is configured to be able to select a channel by a channel selection signal from a microcomputer 5 with a built-in timer. Also plug 2
The commercial alternating current power source obtained in this case is supplied to an alternating current outlet 7 of the receiver 1 via a connection switch 6 controlled by a control signal from a microcomputer 5. In this example, an FM modulation circuit (frequency modulation circuit) 8 is inserted between the connection switch 6 and the AC outlet 7. Also, the commercial AC power obtained from the plug 2 is supplied to the microcomputer 5 with a built-in timer. This microcomputer 5 with a built-in timer has a timer, and also forms a channel selection signal by operating the keys on the keyboard 5a and supplies it to the radio receiver body 4, and also controls the connection switches 3 and 6 at set times according to the program. The system is designed to obtain a signal and supply a modulated signal to a predetermined FM modulation circuit 8 at the set time. in this case
In the FM modulation circuit 8, for example, 50Hz is generated by a pre-programmed DC signal from the microcomputer 5.
The alternating current of
Hz, 200 Hz, 300 Hz and 400 Hz signals, and the tape recorder 9, which will be described later, can be remotely controlled using this frequency modulated signal, such as recording, stop, rewind, and play states. That is, in the microcomputer 5 with a built-in timer, a predetermined program is stored in advance in the microcomputer 5 by operating the keyboard 5a, and according to this program, control signals are generated to control the connection switches 3 and 6 on and off, and the radio It generates a tuning signal for the receiver body 4 and a modulation signal for remote control.

A control signal for switch on/off from the microcomputer 5 with a built-in timer is supplied as a control signal for the movable contacts of the connection switches 3 and 6, and a modulation signal for remote control is supplied to the FM modulation circuit 8. At the output side, that is, at the AC outlet 7, an AC power source whose frequency is modulated as a remote control signal is obtained. Also, the channel selection signal from the microcomputer 5 with a built-in timer is supplied to the radio receiver body 4 so as to receive a desired radio broadcast, and the audio signal obtained in the radio receiver body 4 is supplied to the audio signal output terminal 4a. Do as you please.

In this example, the audio signal obtained at the audio signal output terminal 4a is supplied to the tape recorder 9 as a recording signal. Also, the AC power source obtained from the AC outlet 7 is supplied to the AC power input terminal of the tape recorder 9 via the AC power line 9a to operate the tape recorder 9 and to demodulate the remote control signal to the tape recorder 9. A demodulation circuit 10 is provided, and this demodulation circuit 10
A frequency-modulated AC power source from the AC outlet 7 is supplied to the AC power source via an AC power line 9a, and the demodulation circuit 10 demodulates this frequency modulated signal. A demodulation signal corresponding to the remote control signal obtained at the output side of the demodulation circuit 10 is supplied to the control circuit 11, and the output signal of the control circuit 11 controls the tape recorder 9 to perform recording, stop, rewind, and play states and the remote control signal. The switching is controlled accordingly.

Since the present invention is configured as described above, for example, the broadcast signal of a desired broadcasting station is recorded on the tape recorder 9 at a desired time A on the previous day, and this recorded information is reproduced on the tape recorder 9 at time B on the next morning. A keyboard 5a is installed on the microcomputer 5 with a built-in timer.
When the program is programmed and stored, first, when time A arrives, the connection switches 3 and 6 are turned on by the control signal from the microcomputer 5 with a built-in timer, and the microcomputer 5 turns on the tape recorder 9.
A remote control signal that sets the recording state, for example, a modulation signal that modulates a 50Hz carrier signal to 100Hz, is supplied to the frequency modulation circuit 8, and this frequency modulation circuit 8
This frequency modulated signal is supplied from the AC outlet 7 to the power source of the tape recorder 9 via the AC power line 9a to put the tape recorder 9 into operation, and the demodulation circuit 10
The demodulated signal obtained at the output side of the demodulating circuit 10 puts the tape recorder 9 into a recording state.At this time, the channel selection signal from the microcomputer 5 with a built-in timer is supplied to the radio receiver main body 4, and thereby the radio The receiver body 4 receives the desired broadcast station,
The reproduced signal of the desired broadcast signal obtained at the output side of the radio receiver body 4 is supplied as a recording signal to the tape recorder 9, and the reproduced signal of the desired broadcast signal is recorded by the tape recorder 9. Thereafter, the connection switch 3 is turned off by a control signal from the microcomputer 5 with a built-in timer, and the tape in the tape recorder 9 is rewinded to a predetermined position by a remote control signal obtained by a modulation signal from the microcomputer 5 with a built-in timer. is off. Next, when time B arrives the next morning, the connection switch 6 is turned on by a control signal from the microcomputer 5 with a built-in timer, and the modulation signal from the microcomputer 5 with a built-in timer turns on the 50Hz commercial AC power supply in the FM modulation circuit 8. The frequency is modulated to 400Hz, and this is connected to the AC power line 9 from the AC outlet 7.
a to the power input terminal of the tape recorder 9 to put the tape recorder 9 into operation, and also to supply this signal to the remote control signal demodulation circuit 10, and send the signal to the output side of this demodulation circuit 10 to put it into the play state. A demodulated signal for switching is obtained, this demodulated signal is supplied to a control circuit 11, and the control circuit 11 puts the tape recorder 9 into a play state. Therefore, the broadcast signal recorded at time A can be automatically listened to at time B. Other programs operate in the same manner as described above.

As described above, according to the present invention, it is possible to remotely control a controlled device such as a tape recorder according to a program recorded at bedtime and when the user wakes up in the morning. Since this is done through the computer, there is an advantage that a controlled device such as a tape recorder can be remotely controlled according to a program without providing any special control line.

It goes without saying that the present invention is not limited to the above-described embodiments, and that various other configurations may be adopted without departing from the gist of the present invention.
