[0002]

2. Description of the Related Art Generally, in a display device placed in a bad environment, a display device is provided to prevent water, oil or dust from entering the display device, or to prevent dirt or damage on a display surface. A covering protective cover is used. In particular, the need for this protective cover is great since the screen is directly touched with a finger or the like on a display that touches the screen.

FIG. 5 is an exploded perspective view of a conventional protective cover (actually open type 4-42687) of a display for touch operation. The display 2 includes a cabinet 23 and a front panel 22 having a screen 21. The front panel 22 is housed in the opening 11 of the mounting board 1 with the front panel 22 protruding forward from the mounting board 1. . The screen 21 not only displays an image, but also inputs a command signal and various data when a predetermined position on the screen 21 is touched with a finger or the like.

The protective cover is provided with a frame 3 provided along an opening edge on the front side of the opening 11 of the mounting board 1 and a decorative panel 7 detachably fixed to an outer peripheral portion of the frame 3. A transparent film 6, which is attached to the back side and is attached so that a window (recess) is in close contact with the screen 21 of the display 2; a first packing 4, which is interposed between the frame 3 and the mounting board 1; A second packing 5 interposed between the transparent films 6 and a mounting jig 8 for mounting the display 2 are provided. Since the front panel portion 22 is covered with the transparent film 6, there is no direct contamination or damage.

FIG. 6 is a sectional view of the protective cover for an indicator. In this figure, when a screw 81 for attaching the display 2 to the attachment jig 8 is tightened, the packing 4 is pressed, and a screw 72 for attaching the decorative panel 7 to the frame 3 is tightened. The packing 5 is clamped. In this way, a sealing structure including the first packing 4, the frame 3, and the second packing 5 is formed between the transparent film 6 and the mounting board 1, so that entry of water or the like into the display 2 is prevented. .

As described above, conventionally, a protective cover for a display has been used, which has the effect of preventing the front panel portion 22 of the display 2 from being stained and of making the display 2 almost completely waterproof and dustproof.

[0007]

However, the conventional protective cover for a display has the following problems.

[0008] The above-mentioned protective cover is intended to be almost completely waterproof and dustproof, and thus has a problem that the structure is complicated and expensive. On the other hand, there has been a practical demand from the industry for realizing an inexpensive protective cover with a simpler structure that has a certain waterproof, dustproof effect even if it is not almost perfect.

Further, when replacing the stained transparent film 6 or when connecting a data input / output cable from the front of the display 2, it is necessary to remove and attach the screws 72 for attaching the protective cover, which is complicated. There were also problems.

An object of the present invention is to solve the above problems and to provide an inexpensive and easy-to-replace display protection cover while maintaining a simple waterproof and dust-proof effect.

[0011]

According to a first aspect of the present invention, there is provided a display protective cover for protecting a display attached to a mounting panel, wherein the transparent cover has substantially the same size as the display, and a transparent film. And a frame having a rubber magnet provided on the outer periphery of the back surface of the above.

According to a second aspect of the present invention, there is provided the protective cover for a display device according to the first aspect, wherein the display has a function of performing a touch operation on a display surface.

According to a third aspect of the present invention, there is provided a protective cover for a display device according to the first aspect, wherein the display has a data input / output connection portion on a front surface.

[0014]

In the protective cover for a display according to the first aspect, the frame holding the transparent film is made of a rubber magnet. Therefore, since this protective cover is only magnetically attached to the mounting board, it can be easily mounted and removed from the mounting board. In addition, the display can be easily protected from water oil and dust due to the close contact between the rubber magnet of the frame and the mounting board.

According to the second aspect of the present invention, the protective cover for a display is used for a display having a function of touching a display surface. Therefore, it is possible to easily attach and remove the protective cover which is easily contaminated by direct contact.

According to the third aspect of the present invention, the protective cover for a display is used for a display having a data input / output connection portion on the front surface. Therefore, when attaching the data input / output cable, removal of the protective cover can be facilitated.

[0017]

FIG. 2 shows the structure of a display protection cover 30 for touch operation according to an embodiment of the present invention. In FIG.
FIG. 2 is a schematic sectional view showing a state in which the protective cover 30 is attached to the display 2. In FIG. 1, a display 2 is a front panel unit 2 having a cabinet 23 and a screen 21.
4, a memory card 42, and a data input / output connector 44.

The display 2 is accommodated in the opening 11 of the mounting panel 1 and is fixed to the mounting panel 1 by a mounting jig 48 with the front panel 24 protruding forward from the mounting panel 1. .

In FIG. 2, the protective cover 30 includes a transparent film 34 having substantially the same size as the front panel 24 and having a window (recess), and a frame 36 provided on the entire outer periphery of the rear surface. I have. The frame 36 is formed of a rubber magnet, and is fixed to the transparent film 34 with an adhesive (or double-sided tape) 40.

In this embodiment, it is assumed that the surface of the mounting board 1 is a magnetic material containing an iron component or the like. When the surface of the mounting plate 1 is not made of a magnetic material such as plastic, a magnetic tape containing an iron component or the like may be attached to the surface of the mounting plate 1 with an adhesive (double-sided tape). The adhesive (double-sided tape) used in this embodiment is water-resistant and chemical-resistant.

The front panel 24 includes a protective cover 30
Is covered with a transparent film 34. The concave portion of the transparent film 34 is in close contact with the screen 21 of the front panel 24. On the screen 21, not only an image is displayed, but when a predetermined position on the screen 21 is touched with a finger or the like via the transparent film 34, a command signal and various data are input.

The front panel 24 is not directly stained because of the transparent film 34. However, the transparent film 34 is soiled and needs to be replaced with a new one. In this case, the protective cover magnetically attached to the mounting plate 1 is simply peeled off from the mounting plate 1 and replaced with a new protective cover. This eliminates the need for removing and attaching screws when replacing the protective cover as in the related art, thereby improving work efficiency.

As shown in FIG. 3, a data input / output connector 44 provided on the front of the front panel 24 is provided.
A data input / output cable 46 is connected to the memory card 42, and the memory card 42 (FIG.
Data) may be downloaded. In such a case as well, similarly, the magnetically attached protective cover 30 can be easily pulled off from the mounting board 1 and the data input / output cable 46 can be connected, so that the working efficiency is improved. .

When the indicator 2 is used in a factory or the like in an environment where iron-based dust floats, the iron-based dust is collected around the frame 36 and the front panel 2
It is also possible to prevent iron-based dust from adhering to the transparent film 34 on the upper surface 4.

On the other hand, the entire display 2 projecting from the mounting board 1 is completely covered by a protective cover 30 placed on the mounting board 1. In addition, since the frame 36 of the protective cover 30 is made of a rubber magnet, even if small dirt or the like adheres to the surface of the mounting board 1 due to the elastic force of the rubber, the frame 36 and the mounting board 1 Are in close contact with each other, so that the intrusion of water, oil and dust can be easily prevented.

As shown in FIG. 4, a rubber packing 38 may be attached to the rubber magnet 36 in order to further enhance the waterproof and dustproof properties of the protective cover 30.

[0027]

According to the present invention, the frame for holding the transparent film is formed of a rubber magnet. Therefore, since this protective cover is only magnetically attached to the mounting board, it can be easily mounted and removed from the mounting board. In addition, the display can be easily protected from water oil and dust due to the close contact between the rubber magnet of the frame and the mounting board. Thus, it is possible to provide an easily replaceable and inexpensive protective cover for a display while maintaining a simple waterproof and dustproof effect.

The protective cover for a display according to the second aspect is used for a display having a function of touching a display surface. Therefore, it is possible to easily attach and detach the protective cover that is easily contaminated by direct contact.

According to the third aspect of the present invention, the display protective cover is used for a display having a data input / output connection portion on the front surface. Therefore, when attaching the data input / output cable, removal of the protective cover can be facilitated.
