The control device controls the door opening and closing device 3 to open and close the opening and closing doors 2 and 2a when the receiving unit 38 receives the infrared signal of the remote control transmitter.

  In addition to the above functions, the control device has a voltage detection sensor for detecting the voltage of the current flowing through the liquid crystal television 9, and the voltage detection sensor detects a change in the voltage of the current flowing through the power cord of the liquid crystal television 9. (When it is higher than a preset voltage, it is determined to be ON, and when it is lower, it is determined to be OFF), thereby opening and closing the doors 2 and 2a in conjunction with the power ON / OFF switching of the liquid crystal television 9. The door opening and closing device 3 is controlled to open and close.

  The control device is configured so that the lower sensor 37 is located on the upper door 2 while the doors 2 and 2a are closed so that the user does not get injured by the fingers 2 and the like being closed by the doors 2 and 2a that are closed from both the upper and lower sides. When the reflection plate 29 is detected, the rotation of the stepping motor 31 is stopped, and the doors 2 and 2a are stopped at the closed position. When the upper sensor 36 detects the reflection plate 29 of the upper door 2 while the doors 2 and 2a are being opened, the stepping motor 31 is stopped and the doors 2 and 2a are stopped at a predetermined opening position. .

  Further, the control device detects that an object is caught between the doors 2 and 2a when the doors 2 and 2a are closed, and stops the movement of the doors 2 and 2a, or stops the movement and opposes it. A function of switching to movement in the opening direction may be provided. The downlight 150 provided on the top plate 15 is turned on as soon as the open / close doors 2 and 2a are opened in response to a control signal from the control device.

(Work)
The operation of the television cabinet T will be described with reference to FIGS.
The liquid crystal television 9 is fixed and accommodated on the back plate 12 in the display device accommodating portion 16 of the television cabinet T. The liquid crystal television 9 includes a receiving unit 90 that receives an infrared signal.
The remote control transmitter can emit an infrared signal which is a remote control signal for turning on / off the power of the liquid crystal television 9.

  As shown in FIG. 1, when the liquid crystal television 9 is not viewed (the power of the liquid crystal television 9 is OFF), the doors 2 and 2a are closed, and the liquid crystal television 9 is connected to the doors 2 and 2a. It is hidden behind and cannot be seen from the outside. Therefore, even if the television cabinet T is placed in a narrow living room, there is no feeling of pressure from the large-screen liquid crystal television 9 at least when not viewing.

[When watching LCD TV 9]
When the remote control transmitter is operated so that the power of the liquid crystal television 9 is turned on, an infrared signal emitted from the remote control transmitter passes through the closed lower opening / closing door 2a and is positioned behind it. The signal is received by the receiver 90 of the liquid crystal television 9 and the receiver 38 connected to the control device.

  When the control device in the control box 39 detects that the receiving unit 38 has received an infrared signal, the door opening / closing device 3 is driven, and the opening / closing doors 2, 2a are immediately opened. The open / close doors 2 and 2a stop when they are opened to a predetermined position.

  Further, when the receiving unit 90 receives the infrared signal, the power source of the liquid crystal television 9 is turned on. As described above, when the opening / closing doors 2 and 2a are opened when the receiving unit 38 receives the infrared signal, the control device opens the opening / closing doors 2 and 2a that are interlocked with turning on the power of the liquid crystal television 9. There is no control.

  Since the doors 2 and 2a are thus opened immediately, when the image is displayed on the liquid crystal television 9, the doors 2 and 2a are already opened, and the liquid crystal television is opened in a very short time from the operation of the remote control transmitter. 9 can be watched.

  If the infrared signal cannot be received by the receiving unit 38 for some reason, the control device detects that the power of the liquid crystal television 9 is turned on and performs control for opening the doors 2 and 2a. . Thereby, although the timing is somewhat delayed as compared with the above-described operation, the open / close doors 2 and 2a are reliably opened. Thereby, opening and closing of the open / close doors 2 and 2a can be performed such that the user is less likely to feel stress.

  In addition, when the receiving unit 38 can receive the infrared signal and the receiving unit 90 cannot receive the infrared signal, the power of the liquid crystal television 9 remains off, and the doors 2 and 2a are temporarily opened by the control of the control device. Although it opens, the control device detects that the power source of the liquid crystal television 9 is OFF, and the doors 2 and 2a are immediately closed.

  Note that the opening / closing speed of the open / close doors 2 and 2a is controlled by the control device, and is relatively slow at the beginning of movement, fast in the middle, and slowed down when approaching the stop position. The opening / closing doors 2 and 2a start to move before the image of the liquid crystal television 9 is displayed almost simultaneously with the ON operation of the remote control transmitter.

  The operation of changing the speed is as much stress as possible to the user before the screen appears because if the door is opened too early when the doors 2 and 2a are opened, the door is opened before the image is displayed on the liquid crystal television 9. This is to prevent you from feeling it. Moreover, the said operation | movement can alleviate the danger that a user pinches a finger | toe with the doors 2 and 2a, when closing the doors 2 and 2a, and can improve safety | security.

[To stop watching LCD TV 9]
When the remote control transmitter is operated to turn off the power of the liquid crystal television 9, the infrared signal is received by the receiver 90 of the liquid crystal television 9 and the receiver 38 connected to the control device.

  When the control device in the control box 39 detects that the receiving unit 38 has received the infrared signal, the door opening / closing device 3 is driven and the opening / closing doors 2, 2a are immediately closed. The open / close doors 2 and 2a stop when closed to a predetermined position.

Further, when the receiving unit 90 receives the infrared signal, the power of the liquid crystal television 9 is turned off. As described above, when the open / close doors 2 and 2a are closed by the reception unit 38 receiving the infrared signal, the control device closes the open / close doors 2 and 2a that are interlocked with the power-off switching of the liquid crystal television 9. There is no control.
When the doors 2 and 2a are closed, the liquid crystal television 9 is hidden behind the doors 2 and 2a and returns to the initial state.

  If the infrared signal cannot be received by the receiving unit 38, the control device detects that the power of the liquid crystal television 9 has been turned off, and performs control for closing the doors 2 and 2a. Thereby, although the timing is somewhat delayed as compared with the above operation, the open / close doors 2 and 2a are reliably closed.

As described above, since the opening / closing doors 2 and 2a are moved up and down to open and close the opening of the display device housing portion 16, the television cabinet T has a width substantially the same as the width of the opening and closing doors 2 and 2a. It becomes possible to manufacture according to.
Therefore, the horizontal size of the television cabinet T can be formed more compactly as compared with a conventional door that is opened and closed by sliding the door in the horizontal direction.

Please refer to FIG. 9 and FIG.
In the drawings, the same or similar parts as those of the television cabinet T are denoted by the same reference numerals, and redundant description of the structure is omitted.
In the television cabinet T2, the surfaces of the open / close doors 2b and 2c are made of woody wood. Unlike the open / close doors 2 and 2a of the television cabinet T, the open / close doors 2b and 2c have a structure that does not transmit an infrared signal as a remote control signal.

Front end plates 130 and 140 having a required width are provided in the vertical direction at both ends on the front side of the cabinet body 1. In FIG. 9, a mounting recess 131 (shown in FIG. 10) having an open back side is formed on the back side (inside side) of the middle portion in the vertical direction of the front end plate 130 on the right side. The mounting recess 131 is formed at the same or substantially the same height as the position where the opening and closing doors 2b and 2c are closed.
A signal passing hole 132 is formed in the thickness portion remaining on the front side of the mounting recess 131 in the front end plate 130 through the thickness portion. In the present embodiment, the signal passage hole 132 is formed with a diameter of 3 mm so that the signal passage hole 132 is not conspicuous in appearance, but is not limited to this size. Alternatively, the signal passage hole 132 may be closed with a light-transmitting material (for example, transparent glass or synthetic resin).

  A receiving portion 38 a is attached to the attachment recess 131. A control device cable 380 is extended from the receiving unit 38a, and the control device cable 380 is connected to the control device in the lower control box 39. Further, a light emitting unit cable 381 is extended from the control device, and a light emitting unit 382 is attached to the tip thereof. The light emitting unit 382 can reproduce and emit an infrared signal having the same information as the infrared signal emitted from the remote control transmitter and received by the receiving unit 38a by the control device.

  The light emitting unit 382 is installed on the left side of the receiving unit 90 in FIG. 9 so that the receiving unit 90 of the liquid crystal television 9 installed in the display device housing unit 16 can sense the light (infrared signal) of the light emitting unit 382. ing. In addition, the installation position of the light emission part 382 will not be limited to this if it is a position which can detect light, For example, it can also install in other places, such as the inner surface side of the side plate 13 of the cabinet main body 1. FIG.

(Function)
The television cabinet T2 operates as follows.
First, regardless of the open / closed state of the open / close doors 2b and 2c, an infrared signal emitted by the remote control transmitter can be received by the receiving unit 38a, and the infrared signal is reproduced by the light emitting unit 382 and the liquid crystal television 9 By receiving by the receiving unit 90, the ON / OFF switching of the open / close doors 2b and 2c and the liquid crystal television 9 can be smoothly linked.

  In addition, as described above, since the open / close doors 2b and 2c do not transmit infrared signals that are remote control signals, various materials that do not transmit infrared signals can be used without being captured by the transparency of the infrared signals. . In addition, the design is excellent, and more various designs are possible than the open / close doors 2 and 2a of the first embodiment, and the merchantability of the television cabinet T2 can be improved.

  Note that the terms and expressions used in this specification are merely explanatory and are not limiting at all, and terms and expressions equivalent to the features described in this specification and parts thereof. There is no intention to exclude. It goes without saying that various modifications are possible within the scope of the technical idea of the present invention.
