  In FIG. 1, the remote control light receiving unit main body 3 shows a partially exposed state when viewed from the front of the display device 1. In FIG. 1, 3a and 3b denote remote control light receiving units. Yes.

FIG. 2 is a plan view of the back surface of the display device 1 of the present invention. The back surface of the display device 1 is covered with a back cabinet 12, and the back cabinet 12 protects an electric circuit such as a printed circuit board on which various electronic components (not shown) inside the display device 1 are mounted, a power supply unit, and the like. to discharged to the outside by a fan (not shown) the heat generated inside the display device 1 comprises a number of exhaust heat hole 13a ₁ ~13a _n. In addition, the rear cabinet 12 is provided with a recess so as to form a handle so that the display device of the present invention can be easily transported and installed.

  In the present embodiment, a remote control light receiving unit main body and a remote control light receiving unit main body storage unit, which will be described later, are fixed at the position A in FIG. 2 and receive infrared light from the remote control 2. The remote control light receiving unit body and the remote control light receiving unit main body storage unit are attached to the back surface of the display device, and the remote control light receiving unit body can be pulled out from the remote control light receiving unit main body storage unit as long as Depending on the arrangement of electric circuits such as a printed circuit board on which various internal electronic components are mounted and a power supply unit, they may be arranged at other positions as appropriate.

  3a is an enlarged perspective view of section B in a state where remote control light receiving body 3 is fixed at position A in FIG. 2, and remote control light receiving body 3 is partially exposed to remote control light receiving body storage 4. Shows the state of being stored. 3b shows that the user hooks his / her finger into the recess 30 on the remote control light receiving unit body 3 from the state of FIG. 3a, and the remote control light receiving unit main body 3 is pulled out from the remote control light receiving unit main body storage unit 4 to be greatly exposed. Indicates the state.

  As will be described later, even when the remote control light receiving unit main body 3 is housed in the remote control light receiving unit main body storage unit 4 as shown in FIG. 3A, the remote control light receiving unit main body storage unit 4 is pulled out from the remote control light receiving unit main body storage unit 4 as shown in FIG. Even so, the infrared light from the remote controller 2 can be received.

  4a and 4b are plan views of the remote control light receiving unit main body 3 and the remote control light receiving unit main body storage unit 4. FIG. 4a shows the remote control light receiving unit main body 3 stored in the remote control light reception unit main unit storage unit 4. FIG. 4 b shows a state in which the remote control light receiving unit main body 3 is pulled out from the remote control light receiving unit main body storage unit 4. Note that the description of the same reference numerals in FIG. 4b as in FIG. 4a is omitted.

  In FIG. 4 a, the remote control light receiving unit main body 3 is fitted into the remote control light receiving unit main body storage unit 4 by a fitting claw 41 integrally formed with the remote control light receiving unit main unit storage unit 4, and a finger is placed in the recess 31 on the remote control light receiving unit main body 3. When it is hooked and pulled out below the display device 1, it slides along a guide 32 integrally formed with the remote control light receiving unit body 3.

  It should be noted that the state in which the positioning member 33 of the remote control light receiving unit main body 3 is in the position of either the positioning unit 43-1 or 43-2 of the remote control light receiving unit main body storage unit 4 is stopped after the remote control light receiving unit main body 3 is slid. If the positioning member 33 of the remote control light receiving unit main body 3 is at the position of the positioning unit 43-1 of the remote control light receiving unit main body storage unit 4 (state of FIG. 4a), the remote control light receiving unit main body 3 is stored in the remote control light receiving unit main body. If the part 4 is partially exposed and located at the position of the positioning part 43-2 (the state shown in FIG. 4b), the remote control light receiving unit main body 3 is pulled out from the remote control light receiving unit main body storage unit 4 and is greatly exposed. Show.

  Further, the remote control light receiving unit main body 3 is in the case where an overload is applied to the remote control light receiving unit main body 3 from below in the state of FIG. 4a (positioning member 33 is the position of the positioning unit 43-1). However, even when an excessive load is applied to the remote control light receiving unit main body 3 in a state where a part is exposed from the remote control light receiving unit main body storage unit 4, the rebound member 34 is formed in the recess D which is the back movement region. By being bent downward (the state of the rebound member 34 in FIG. 4c), the load is absorbed, and when the load disappears, the structure acts to return to the state of FIG. 4a. Yes.

  Further, the remote control light receiving unit body 3 has a guide base 32A at the remote control light receiving unit body so that the remote control light receiving unit body 3 is not pulled out more than necessary from the state shown in FIG. 4B (positioning member 33 is positioned at the positioning unit 43-2). The remote control light receiving unit main body 3 is prevented from being pulled out of the position by contacting the stopper 42 integrally formed with the storage unit 4.

  Further, the remote control light receiving portions 3a and 3b of the remote control light receiving portion main body 3 are formed of a transparent member, and the LED light receiving portions 3c and 3d are incorporated therein. A main body switch 35 for turning on and off the power is provided. In the present embodiment, only one switch 35 is provided. However, it is also possible to perform setting of the display device by separately providing a plurality of switches.

  FIG. 5 is a perspective view of FIG. 4A, and FIGS. 6A and 6B are perspective views of the remote control light receiving unit main body 3 and the remote control light receiving unit main body storage unit 4, respectively. Note that the description of the same reference numerals in FIG. 4b as in FIG. 4a is omitted.

  5 and 6a, the above-mentioned remote control light receiving portions 3a and 3b have an L-shape, and the remote control light receiving portion main body 3 is only partially exposed from the remote control light receiving portion main body storage portion 4. Even in the absence, the positions of the light receiving portions 3a and 3b can be visually recognized from the front of the display device 1, and infrared light from the remote controller 2 can be received from below.

  Further, when the remote control light receiving unit main body 3 is pulled out and largely exposed, the LED light receiving units 3c and 3d are exposed so that they can be seen from the front, and the infrared light of the remote control 2 is received from the front. It can be done. Further, in this state, the switch 35 is also exposed, so that it is possible to control the on / off switching of the display device power supply in an emergency, such as when the remote control is temporarily lost or when the battery of the remote control is exhausted.

  In the present embodiment, the case where the remote control light receiving device is provided in the display device has been described. However, the remote control light receiving device of the present invention can also be used for an electronic device in which the remote control light receiving unit cannot be disposed on the front surface of the device. It has versatility.
