The main body support part and the main body are connected by a rotating means, and the front surface of the main body is directed toward the remote controller in response to the output of the remote control position detection signal light receiving means.

According to the above configuration, the present invention can detect the remote control position using an infrared signal emitted from the remote control, and can direct the television screen toward the remote control.

EXAMPLE Hereinafter, a television remote control position detecting device according to an example of the present invention will be described with reference to the drawings.

FIG. 1 shows a remote control position detection device in one embodiment of the present invention. In FIG. 1, numeral 1 denotes a remote control, and numeral 2 denotes a light receiving section which includes remote control position detection means and normal signal detection means. A signal from the remote control 1 to the light receiving section 2 is sent using infrared light. The function of detecting the position of the remote control is detected by the angle of incidence of infrared light on the light receiving section 2.

22 and 23 are reflectors for narrowing the directivity, and 25 is a light-receiving bare hand for normal signal detection. Light receiving element 2
1, 22, and 23 are fixed in different directions, and the reflector 24 provides narrow directivity, and the optical directivity of each receiving sensitivity is 21' in Fig. 4. , 22', 23'. Therefore, the Gallos property of the infrared light from the remote control is
This can be determined based on the output current level of 2.23.

The light receiving element 25 has wide receiving sensitivity as shown in 25' in FIG. 5, and can receive normal signals from any direction.

In FIG. 1, 26 is a switching circuit for a remote control position detection signal and a normal signal, 27 is an amplifier circuit, 28 is a tuning/detection circuit, and 29 is a waveform shaping circuit. Remote control 1
When the normal signal is sent from n, the normal signal operation signal O
As a result, the signal from the normal signal detection light receiving element is outputted as a normal signal through the amplifier circuit 27, the tuning/detection circuit 28, and the waveform shaping circuit 29. When the position detection signal is being sent from the remote control 1, the remote control position detection operation signals A, B, and C are sequentially switched, and the remote control position detection light receiving element 21, 22, 23 corresponds to each n. The signal from the remote controller is outputted as a remote control position signal through an amplifier circuit 27 and a tuning/detection circuit 28.

The light receiving section 2 is attached to the same surface as the screen 33 of the television main body 30, and the television main body 30 is connected to a stand 32 via a motor 31. When a person (not shown) who wants to watch TV operates the remote control 1 at hand, the light receiving section 2 detects the direction of the remote control 1, detects the difference between the direction of the remote control 1 and the direction of the TV screen 33, and activates the motor 3.
