Abstract

(57) [Abstract] [Purpose] To check the operating status of the controlled device, check the operating status of the controlled device in close proximity to the remote control device that had to look at the display of the controlled device. It is an object of the present invention to provide a bidirectional remote control device that can be used. [Structure] The remote control device main body 2 is provided with a receiver 7 and the controlled device 1 is provided with a transmitter 6, and a signal transmitted from the transmitter 3 is received by the receiver 4 and decoded by a decoder, according to the contents thereof. The signal is transmitted from the transmitter 6 and received by the receiver 7, and the content is displayed on the display unit 8 so that the operating state of the controlled device 1 can be confirmed in the immediate vicinity of the user.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bidirectional remote control device used in various electronic devices.

[0002]

2. Description of the Related Art FIG. 3 shows a configuration of a conventional remote control device, in which an output of a modulator 10 which modulates a signal of a signal generator 9 is controlled by a switch 11 and a command is transmitted from a transmitter 12. Then, the controlled device receives the command and operates, and the operating state is added to the controlled device.
Etc. are displayed on the display device.

As described above, even in the above-mentioned conventional remote control device, the controlled device causes the display device such as an LCD to display the operating state, so that the user can check the operating state of the controlled device. It was possible.

[0004]

However, in the above-mentioned conventional remote control device, for example, when the display indicating the reception of the command does not appear on the controlled device or when the display is too far away to be seen by the user, There is a problem that it is difficult to confirm the operating state of the control device.

The present invention has been made to solve such a conventional problem, and an object of the present invention is to provide a function of allowing the operating state of a controlled device to be known in the main body of the remote control device, that is, in the vicinity of oneself. To do.

[0006]

In order to achieve the above object, the present invention transmits the operating state of a controlled device by providing a receiver in the main body of the remote control device and a transmitter in the controlled device. The operation state of the controlled device can be confirmed by displaying the contents transmitted from the device and received by the receiver on the display unit.

[0007]

Therefore, according to the present invention, by providing the remote control device main body with the receiver and the controlled device with the transmitter,
This has the effect that the operating state of the controlled device can be confirmed by the remote control device itself, that is, in the immediate vicinity of itself.

[0008]

1 and 2 show the structure of an embodiment of the present invention, in which 3 is a command transmitter and 7 is a second receiver, which is added to the main body 2 of the remote control device. There is. Reference numeral 4 is a first receiver, 6 is a second transmitter, and 5 is a decoder, which is built in the controlled device 1. The command transmitter 3 transmits it, the first receiver 4 receives it, the decoder 5 decodes it, and the second transmitter 6 transmits a signal according to its content, and the second receiver 7 transmits it. The information is received and displayed on the display unit 8 such as an LCD provided in the remote control device body 2.

The second receiver 7 is operated only for a certain period of time after transmitting the command from the command transmitter 3. This is because the second receiver 7 consumes a large amount of current.
This is because the remote controller main body 2 is operated by a battery, so that the battery consumption is reduced as much as possible.

The second transmitter 6, after receiving the signal from the command transmitter 3 by the first receiver 4, transmits the signal only for a necessary minimum time. This is to prevent interference with other electric devices and prevent other electric devices from malfunctioning.

By doing so, it is possible to obtain the effect that the operating state of the controlled device 1 can be confirmed very close to the user without interfering with other electric devices.

Further, the main body 2 of the remote control device is provided with a learning function, which has the effect of being able to operate electric devices of different manufacturers.

[0013]

As is apparent from the above embodiments, the present invention provides a remote control device main body with a receiver and a controlled device with a transmitter, and transmits the operating state of the controlled device from the transmitter to the receiver. Thus, there is an effect that the operating state of the controlled device can be confirmed very close to the user. Further, by operating the receiver for a certain period of time, the battery consumption is reduced, and the transmission from the transmitter has an advantage of preventing interference with other electric devices by making the transmission time very short.
