A support bar protruding inwardly of the case and penetrating the bar hole of the receiver; And an elastic body having one end contacting the inner surface of the case and the other end contacting the receiving part and surrounding the support bar.

In order to achieve the above object, the present invention is a case formed with an exposure hole; A boss projecting inwardly of the case; A reception window exposed through the exposure hole; A receiving unit coupled to the receiving window to receive a remote control signal and having a boss hole for penetrating the boss; A fixture engaged with the boss; And it is coupled to the fixed body and provides a display device having a remote control receiver including an operation unit for moving the receiver while moving.

Hereinafter, with reference to the accompanying drawings will be described an embodiment of a remote control receiver and a display device having the same according to the present invention.

In this process, the thickness of the lines or the size of the components shown in the drawings may be exaggerated for clarity and convenience of description.

In addition, terms to be described later are terms defined in consideration of functions in the present invention, which may vary according to a user's or operator's intention or custom.

Therefore, definitions of these terms should be made based on the contents throughout the specification.

3 is a view showing a coupling relationship of a remote control receiving apparatus according to an embodiment of the present invention, Figure 4 shows a state in which the receiving window of the remote control receiving apparatus according to an embodiment of the present invention is exposed to the same line as the case 5 is a diagram illustrating a state in which a reception window of the remote control receiver according to an embodiment of the present invention protrudes from a case.

3 to 5, an exposure hole 31 is formed in the case 30 forming the exterior of the product. The boss 32 protrudes inside the case 30. A receiving window 41 is positioned in the exposure hole 31 to expose the product.

A fine gap may be formed between the exposure hole 31 and the reception window 41, and a rubber member 44 may be formed to fill the gap.

The reception window 41 is designed to refract the infrared signal transmitted from the remote control 60, and is mounted on the reception unit 40 that receives the remote control 60 signal and controls the product to be driven according to the received signal.

The receiver 40 includes a decor sensor and a printed circuit board, and a boss hole 42 for penetrating the boss 32 is provided.

The boss 32 is fastened to the fixed body 43. The fixture 43 is in contact with one side of the receiver 40 while being fastened to the boss 32, so that the receiver 40 is not separated from the case 30.

The fixture 43 penetrates the inside to surround the boss 32 and may be coupled to the boss 32 by screwing a screw at an end thereof. In addition, the fixture 41 may be directly screwed with the boss (32).

The fixing unit 43 is provided with an operating unit 50 to move the receiving unit 40.

The operation unit 50 includes a moving body 51 and a drive motor 52. The movable body 51 is coupled to the screw thread 45 provided on the outer circumferential surface of the fixing body 43, and is provided with teeth on the outer circumferential surface to contact the side of the receiver 40. The drive motor 52 rotates the moving body 51 in engagement with the teeth.

The driving motor 52 may be operated when the power is applied to the electronics and rotated in one direction. The driving motor 52 may be operated when the power is cut to the electronics and rotated in the other direction or may be driven by an operation signal of the remote controller 60. .

On the other hand, the support bar 36 protrudes from the inside of the case 30, and the receiving unit 40 is provided with a bar hole 46 through which the support bar 36 passes. The support bar 36 is designed to be spaced a predetermined interval to guide the stable movement of the receiver 40.

An elastic body 37 is wrapped around the outer circumferential surface of the support bar 36. One end of the elastic body 37 is in contact with the inner surface of the case 30 and the other end is in contact with the receiver 40 to retain the elastic force when the distance between the receiver 40 and the case 30 is narrowed.

The remote control receiver may be applied to a display device such as a television, and may be applied to various electronic products using the remote control receiver.

Referring to the operation of the remote control receiver and the display device having the same according to the present invention having the above structure as follows.

Power is applied to the electronic product through a power button provided in the remote controller 60 or the electronic product itself, or through a separate function button of the remote controller 60, the driving motor 52 is driven in one direction.

The moving body 51 is rotated in the other direction by the drive of the drive motor 52 to press the receiving unit 40, the pressurized receiving unit 40 is close to the case (30).

When the receiver 40 approaches the case 30, the reception window 41 protrudes toward the front of the case 30 by the moving distance of the receiver 40 as shown in FIG. 5. At this time, the elastic body 37 located between the receiver 40 and the case 30 is contracted.

Then, since the protruding reception window 41 can receive the signal of the remote controller 60 more clearly, the reception ratio to the remote controller 60 is improved.

On the other hand, the power is cut off for the electronic products or through a separate function button of the remote control 60, the drive motor 52 is rotated in the other direction and the moving body 51 is rotated in one direction away from the receiver 40.

At this time, by the elastic restoring force of the contracted elastic body 37, the receiver 40 is pushed out of the case 30 and moved to its original position.

Although the present invention has been described with reference to the embodiments shown in the drawings, this is merely exemplary, and those skilled in the art to which the art belongs can make various modifications and other equivalent embodiments therefrom. Will understand.

Therefore, the true technical protection scope of the present invention will be defined by the claims below.
