Abstract

PURPOSE:To prevent a dustproof function from falling at a sealing elastic body in a display apparatus wherein a display device is installed inside a case on which a screen is formed and a part between the screen and the display device is sealed by the sealing elastic body for dustproof. CONSTITUTION:A printed-circuit board 3 to which a display device (LCD) 1 has been fixed is held inside a case 7 by a hook piece 11 or the like, the display device 1 is arranged to face a screen 8 installed on the case 7, and a rubber packing (a sealing elastic body) 4 is mounted elastically between the printed- circuit board 3 and the inner face of the case 4 to surround the display device 1. When the rubber packing 4 is formed in such a way that its height is larger than the thickness of the display device 1, its elastic contraction amount is made large. Even when the size between the case 7 and the display device 1 is changed, a sealing effect is ensured by following this change, and it is possible to prevent a dustproof function from falling.

2. Description of the Related Art Conventionally, as this type of dustproof structure, a structure shown in a partially exploded perspective view of FIG. 4 and a sectional view of FIG. 5 has been adopted. In these figures, 1 is L as an indicator
It is a CD and is fixed to the printed board 3 by the LCD frame 2. Then, the printed board 3 is attached to the case 7
The display device is constructed by arranging the LCD 1 and the LCD 1 facing the screen 8 provided in the case 7. At this time, the space formed by the LCD 1 or the LCD frame 2 and the inner surface of the case 7 or the screen 8 may be sealed, but a slight backlash between the LCD frame 2 and the inner surface of the case 7 causes a gap between them. It is difficult to completely seal it because of the occurrence of. Therefore, a rubber packing 4A is sandwiched between the LCD frame 2 and the inner surface of the case 7 as an elastic body for sealing, and the rubber packing 4A is contracted between the two to enhance the close contact between the two and seal without any gap. , To prevent intrusion of dust and dirt. In this case, as shown in JP-A-2-84617, L
It is also proposed that a protrusion-shaped elastic body is provided at the edge of the CD frame, and the protrusion is crushed to seal between the LCD frame and the inner surface of the case to prevent intrusion of dust. , Which is basically the same as described above.

In such a conventional dustproof structure, since the rubber packing 4A is inserted between the LCD frame 2 and the inner surface of the case 7, the rubber packing 4A is provided.
Has a thickness corresponding to the gap between the two and is thin. Therefore, the elastic shrinkage amount of the rubber packing 4A is small, and some impact is applied to the receiver such as when the receiver is dropped, so that the rubber packing 4A is separated between the LCD frame 2 and the inner surface of the case 7. When a gap larger than the amount of elastic contraction occurs, the rubber packing 4A can no longer seal the gap, and the dustproof function is deteriorated. An object of the present invention is to provide a dustproof structure that prevents such deterioration of the dustproof function.

At this time, since the rubber packing 4 has a size higher than that of the LCD frame 2, its length in the elastic contraction direction is large, and therefore the contraction amount can be large. Therefore, even if the gap between the LCD 1 and the screen 8, that is, the gap between the LCD frame 2 and the inner surface of the case 7 is increased when a shock is applied by dropping the receiver or the like. Following this, it is possible to reliably seal the gap between the two, and it is possible to prevent dust and dirt from entering the LCD 1. Further, here, the rubber packing 4 is in contact with the rib 9 on the outer peripheral surface thereof, so that the rubber packing 4 and the case 7 are
The contact area with the rib 9 can be increased by the contact area with the rib 9, and the sealing performance can be improved.

As described above, according to the present invention, the elastic elastic body for sealing is mounted between the printed board to which the display is fixed and the screen provided in the case so as to surround the display. , The elastic body for sealing can be set to a large height, which allows a large elastic contraction amount of the elastic body for sealing to be achieved even if the gap between the display and the case is changed. Following this, the gap can be sealed and the dustproof effect can be enhanced. Especially, by setting the gap between the printed board and the screen to be larger than the thickness of the display and smaller than the height of the sealing elastic body, the height of the sealing elastic body can also be set to this spacing size. Therefore, the elastic shrinkage amount can be increased. Further, the square hole or the notch is engaged with the hook piece to hold the printed board in the case, and the hook piece on one side has flexibility to rotate the printed board in the board thickness direction. Thus, the work of assembling and removing the printed board in the case can be easily performed. Also,
By arranging the ribs upright on the case so as to surround the sealing elastic body, the contact area between the case and the sealing elastic body can be increased, and the sealing effect can be enhanced.
