In addition, the sensor 212, in a state where it is mounted on the support 211, when the protruding means 220 is operated, moves together with the support 211 and through the opening 111 formed on the mask front 110. In order to protrude to the outside of the main body 100, it is preferably formed in a shape corresponding to the opening 111 and has a sufficient thickness so as to protrude to a certain portion to the outside. Here, the sensor 212 protruding outside the main body 100 can receive the infrared signal of the remote control not only through the front side but also through the top, bottom, left, and right sides thereof, and thus, the reception range is significantly increased, thereby exhibiting a significantly improved reception performance. .

According to the receiver 210 according to the exemplary embodiment of the present invention, as described above, the sensor 212 disposed inside the main body 100 is formed in the mask front 110 of the main body 100 as necessary. Since the sensor 212 is normally located inside the main body 100 through the opening 111, the sensor 212 is naturally harmonized with the overall appearance of the main body 100, and the sensor 212 is When protruding to the outside of the main body 100 has the advantage that it provides a significantly improved reception performance than when located inside the main body 100.

On the other hand, the protruding means 220, which is provided to provide a force for pushing the receiver 210 as described above to the outside of the main body 100 to the receiving unit 210, the body 100, more specifically Is disposed at the rear of the receiving module 200 according to an embodiment of the present invention, and includes a receptor 221 and the protrusion 222.

Among these, the receptor 221 is disposed on one side of the receiver 210, more specifically, the rear side of the receiver 210 and is fixed inside the main body 100, and the protrusion 222 is the receptor 221. ) Is mounted inside.

Here, the protrusion 222 may be activated or deactivated by the operation means 230 to be described later in the state mounted inside the container 221 as described above. ) By pushing outward from the inside to push the receiving unit 210 out of the main body 100, and when the operation is released by the operating means 230, the receiving unit 210 may be inserted into the main body 100 again. To be inserted back into the receptor 221.

The principle of operation and deactivation of the protruding body 222 may be a principle of operation of a ballpoint pen, which repeatedly protrudes and inserts a ballpoint pen by a user's repeated pressing operation. Since it is a general matter that can be easily applied, a detailed description thereof will be omitted here.

Hereinafter, the structure of the above-mentioned operation means 230 will be described.

As described above, the operation means 230 is provided to operate the protrusion means 220, and performs the operation of operating or releasing the protrusion means 220 according to the user's operation.

The operation means 230, one side thereof protrudes outside the main body 100, the other side is connected to the protruding means 220 inside the main body 100, that is, the mask front 110 outside the main body 100 By passing through the other side is provided in a form that is fixed on the protrusion 222 of the protruding means 220, when one side is repeatedly pressed in response to the user repeatedly pressing, according to the protruding means 220 The other side connected to the protrusion 222 of the press the protrusion 222 to repeat the operation to activate or deactivate the protrusion 222.

Finally, the elastic means 240, when the above-described protruding means 220 is deactivated, that is, when the protrusion 222 is inserted into the container 221, the protruding means 220 protrudes outside the container 221. It provides elastic restoring force for inserting the receiver 210 protruding to the outside by the protrusion 222 into the main body 100, and is disposed between the mask front 110 and the receiver 210 of the main body 100. do.

Hereinafter, an operation relationship of an electronic device according to an embodiment of the present invention will be described with reference to FIGS. 5 to 6C.

As shown in FIG. 5, the electronic device 300 according to an embodiment of the present disclosure may position the sensor 212 of the receiver 210 in the main body 100 according to a user's need, or the main body ( 100) It may be protruded to the outside. First, referring to Figure 6a to describe the operation of the receiving module 200 according to an embodiment of the present invention, the user who operates the remote control and the mask front 110 When the angle between the sensor 212 of the receiving unit 210 exposed through the formed opening 111 (see FIG. 3) is an angle within a range in which the sensor 212 can receive an infrared signal inside the main body 100. As in the conventional electronic device, the sensor 212 may receive the infrared signal of the remote controller from the inside of the main body 100 through the opening 111.

In this state, the angle between the user who operates the remote control and the opening 111 formed in the mask front 110 is greater than or equal to a certain range, so that the sensor 212 is difficult to receive an infrared signal through the opening 111. In this case, when the user presses the operation means 230, as shown in FIG. 6B, the operation means 230 is pressed toward the inside of the main body 100, and a protrusion inserted into the receiver 221. By pressing and operating 222, the protrusion 222 protrudes out of the receptor 221, and thus the protrusion 222 protruding out of the receptor 221 pushes and moves the support 211. .

Accordingly, the sensor 212 mounted on the support 211 moves along the support 211 and protrudes to the outside of the main body 100 through the opening 111 formed in the mask front 110. The elastic means 240 disposed between the rear surface and the support 211 is contracted as the support 211 moves as described above to have elastic restoring force.

On the other hand, when the user pushes the operation means 230 again to position the protruding sensor 212 in the main body 100 again, as shown in FIG. 6C, the operation means 230 is While being pressed back toward the inside of the main body 100, pressing the protrusion 222 protruding out of the receptor 221 is released, that is, the protrusion 222 is inserted into the receptor 221. In response to the movement of the protrusion 222, the elastic means 240 that has been contracted is restored and the support 211 is pushed and moved. The movement of the support 211 protrudes out of the main body 100. The sensor 212 was also moved back into the main body 100 together.

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. In addition, although the display device has been described as an example, this is merely illustrative, and the present invention may be applied to other electronic devices. Therefore, the true technical protection scope of the present invention will be defined by the claims below.

As described above, according to the electronic device according to the present invention, unlike the prior art, the receiving module is provided to repeat the insertion or protrusion into or out of the main body according to the user's needs, the receiving module according to the user's needs When protruding out of the main body, while providing a significantly improved reception performance compared to the conventional infrared receiving module, the receiving module is usually inserted into the main body has the advantage that it can maintain a naturally harmonized state without harming the overall appearance of the main body.
