An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a circuit diagram of a remote control operation unit 1 of a remote control device according to this embodiment. The remote control operation keys 2 and an LED drive I for generating a remote control signal are shown.
C3, the output of the LED driving IC 3 is input to the base of a transistor 5 connected in series with the infrared LED 4 for transmitting a remote control signal. The remote controller 1 has a receiving circuit for a search signal transmitted from the television 6 as shown in FIG. The search signal receiving circuit is provided so that a radio wave received by the antenna 7 is detected by a detection circuit 8 and a received signal is input to a gate of a p-type MOSFET 10 via an amplifier 9. The source side of the p-type MOSFET 10 is connected to an oscillation circuit 11, and the output of the oscillation circuit 11 is connected to a vibration member 12 such as a piezoelectric element or a speaker.

The drain of the remote control LED 4 and the FET 10 to which the search signal is input are connected to a power supply 13 via a changeover switch 14. The changeover switch 14 is always turned on by falling to the FET 10 side, and is linked to the LED 4 side to connect the LED 4 and the battery 13 in conjunction with the operation of the operation key 2.

A search signal transmission circuit in the television 6 is operated by a switch 21 as shown in FIG.
The output of the square wave generator 16 is input to the mixer 17. The output of the oscillation circuit 18 is also input to the mixer 17, a search signal having a predetermined signal waveform is output from the mixer 17, and a search signal is transmitted from the antenna 20 via the high frequency amplifier 19.

In the remote control device of this embodiment, the remote control of the television 6 can be performed by the operation keys 2 of the remote control operation unit 1, and the remote control operation unit 1 can be searched from the television 6 side. This search is performed, for example, when the user does not know where the remote control operation unit 1 is.
What is necessary is just to press the switch 21 of the television 6. The switch 21 is provided corresponding to each remote control operation unit 1 so that when there are a plurality of remote control operation units 1, each can be searched separately. When the switch 21 is pressed, the square wave generating circuit 16
Generates a square wave set at a predetermined duty ratio. Then, this square wave is input to the mixer 17,
The carrier signal of the oscillation circuit 18 is added to the high frequency amplifier 19 by the mixer 17, amplified, and transmitted as a search signal from the antenna 20.

The search signal transmitted from the antenna 20 is input to the antenna 7 of the remote control operation unit 1, detected by the detection circuit 8, shaped and amplified by the amplifier 9, and input to the gate of the FET 10. Thereby, F
The square wave generated by the square wave generation circuit 16 is input to the gate of the ET 10, the FET 10 is turned ON only when the square wave is High, and the oscillation circuit 11 outputs an oscillation signal of a predetermined frequency. Then, the vibration member 12 vibrates according to the oscillation signal, and an oscillating sound is output, so that the location of the remote control operation unit can be found.

According to the remote control device of this embodiment, even if the remote control operation unit 1 is lost, an oscillating sound is emitted from the remote control operation unit by pressing the switch 21 of the television 6, and the location of the remote control operation unit can be easily determined. You can know.

Further, since the output of the search signal receiving circuit of the remote control operation section is switched by the MOSFET 10, the power consumption when not in use is small and the battery 13 is not used.
Consumption can be reduced.

The remote control device according to the present invention may be configured as an oscillator for a small electronic device, in which a search signal receiving circuit and a vibration member are unitized to be detachable from the remote control device. The oscillator for a small electronic device such as the search signal receiving circuit may be detached so that it can be mounted on other valuables. As a result, not only the remote control operation unit but also other valuables can be prevented from being lost.

According to the remote control device and the oscillator for a small electronic device of the present invention, a search signal receiving circuit is provided in a remote control operation portion or the like, and an oscillating sound is generated by a search signal emitted from the electronic device side. When it is no longer known where, etc. are located, the location can be easily found. In particular, when a large number of people share one remote control operation unit or the like, or when various electronic device remote control operation units are mixed, the location of the remote control operation unit or the like of a specific electronic device is lost. In many cases, the user can immediately find the remote control of the electronic device. In a small electronic device in which the search signal receiving circuit consumes very little power and a large battery is not provided, there is no wasteful power consumption and the battery life is not shortened.
