BACKGROUND OF THE INVENTION
The present invention relates to a thin information processing apparatus typified by a notebook personal computer, and more particularly to an information processing apparatus considering dust resistance and waterproofness.
[0002]
[Prior art]
2. Description of the Related Art Thin information processing devices typified by notebook personal computers have become widespread as information processing devices that are convenient to carry by downsizing and high integration of semiconductor devices. This type of information processing apparatus is often used outdoors because it is convenient to carry, and dustproofing against dust and waterproofing against rain and the like are important.
[0003]
A structure of an information processing apparatus in consideration of conventional dustproofness and waterproofness will be described with reference to FIG.
[0004]
FIG. 5 is a partial cross-sectional view showing a structure of a main part of a conventional information processing apparatus.
[0005]
The liquid crystal unit 503 is held by a front housing 501 and a rear housing 504. A protective panel 502 for protecting the liquid crystal unit 503 is disposed at a predetermined interval in front of the display surface of the liquid crystal unit 503 (above the drawing).
[0006]
Actually, in addition to the constituent members shown in the figure, a central processing unit, an input device, a storage device, and the like are provided, and the liquid crystal unit 503 displays information according to a video signal sent from the central processing unit.
[0007]
In this conventional example, the liquid crystal unit 503 and other constituent members are sealed by the front casing 501, the rear casing 504, and the protective panel 502 combined with the front casing 501, thereby providing dust resistance and waterproofing. It is intended to improve. The front housing 501 and the rear housing 503 are made of a resin member such as plastic. Further, the protective panel 502 is made of a resin member such as transparent glass or acrylic so that the display content of the liquid crystal unit 503 can be confirmed. Since both of these must be combined to seal the inside of the housing, a hard material that does not easily deform is used.
[0008]
[Problems to be solved by the invention]
In the conventional information processing apparatus described above, the front housing 501 and the rear housing 503 are made of a resin member, and the protective panel 502 is made of a resin such as transparent glass or acrylic.
[0009]
However, it is difficult to manufacture the resin member straight, and some deformation occurs at the time of manufacture as compared with the design shape. Furthermore, deformation is further caused by external factors such as impact and changes with time such as temperature.
[0010]
FIG. 6 is a diagram illustrating a state in which the front housing 501 is deformed and a gap d is generated between the front housing 501 and the protective panel 502. Due to the occurrence of the gap d, there is a problem that the sealing performance of the housing becomes low, and the dustproofness and waterproofness are deteriorated.
[0011]
In addition, since the protective panel 502 serves to protect the structural members inside the housing, it is provided at the boundary in contact with the outside, but as a material thereof, a hard glass or resin member that is not easily deformed is used. Therefore, there is a problem that the information processing apparatus cannot be adapted to the touch panel. In this type of information processing apparatus, there are various input situations when used outdoors, but a touch panel that can be input simply by pressing the screen is a very effective input means, and is used by the touch panel. If this is not possible, the application will be limited.
[0012]
The present invention has been made in view of the problems of the conventional techniques as described above, and can maintain the sealing property, dustproof property and waterproofness of the housing for a long period of time, and also uses a touch panel. An object of the present invention is to realize an information processing apparatus capable of performing the above.

[0021]
DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the present invention will be described with reference to the drawings.
[0022]
FIG. 1 is a cross-sectional view showing a main configuration of an embodiment of an information processing apparatus according to the present invention, and FIG. 2 is a cross-sectional view showing a state when deformation occurs in a housing.
[0023]
An image display unit 103 which is a thin display device such as a liquid crystal unit or a plasma display panel is held by a front housing 101. A protective sheet 102 for protecting the image display unit 103 is disposed at a predetermined interval in front of the display surface of the image display unit 103 (above the drawing). The protective sheet 102 is in contact with the front housing 101 on one side and in contact with the support member 105 on the other side. The support member 105 is provided between the protection sheet 102 and the image display unit 103, and the support member 105 determines the interval between the protection sheet 102 and the image display unit 103.
[0024]
In this embodiment, the front housing 101 has an opening surface for the user to check the image display unit 103, and the protective sheet and the protection sheet 102 are covered with the periphery of the opening surface. Close. The constituent members are hermetically sealed by the front casing 101, the rear casing 104, and the protective sheet 102 combined with the front casing 101, thereby improving dustproofness and waterproofness.
[0025]
Actually, in addition to the components shown in the figure, a central processing unit, an input device, a storage device, and the like are provided in the same manner as the conventional example shown in FIG. Displays information according to the signal.
[0026]
The protective sheet 102 in this embodiment is not easily deformed such as glass or acrylic, but has flexibility and resilience that returns to its original shape after being deformed when pressed, and is elastic, for example, thin Polyimide, polyester, etc. are used.
[0027]
As for the distance between the protective sheet 102 and the image display unit 103, interference fringes called Newton rings are observed if these distances are reduced to a certain extent. To prevent this, the protective sheet 102 and the image display unit 103 Is about 0.5 mm at the end.
[0028]
The image display unit 103 is disposed so as to be held in the front housing 101, and is connected to the front housing 101 by a connecting member (not shown) via the support member 105 and the protective sheet 102, thereby the front housing. Each of the body 101, the protective sheet 102, the image display unit 103, and the support member 105 is in a pressure-contact state, and the support member 105 is combined in such a manner that the protective sheet 102 is not peeled off from the front housing 101. 102 is pressed against the front casing 101 to maintain hermeticity.
[0029]
The support member 105 is provided in order to prevent the occurrence of the above-described Newton ring by generating a stable pressing force to maintain hermeticity and maintaining an appropriate distance between the protective sheet 102 and the image display unit 103. . The support member 105 of the present embodiment is made of a material that has a height of about 1 mm when no load is applied, and is about 0.5 mm when coupled by the connecting member. The distance between the protective sheet 102 and the image display unit 103 is about 0.5 mm at the end. Examples of the material of the support member 105 include rubber and sponge, and are not particularly limited as long as they have elasticity.
[0030]
Although the front housing 101 has an opening surface for the user to check the image display unit 103, the connecting portion by the connecting member is bent even when the front housing 101 is pushed by the support member 105. In order to prevent this from happening, it is in the vicinity of the opening surface.
[0031]
The contact surface of the protective sheet 102 with the front housing 101 is formed thicker than other portions. As described above, since the protective sheet 102 and the front casing 101 are placed in pressure contact with each other, if the flat sheet shape is used, the front casing 101 and the part of the front casing 101 are partially deformed when the protective sheet 102 is deformed by the pressing force. This is because it peels off. This is because if the protective sheet 102 is peeled off from the front housing 101 even a little, there is a risk that water may enter the housing due to capillary action.
[0032]
In the present embodiment, as described above, the contact surface of the protective sheet 102 with the front housing 101 is formed thicker than the other portions, so that even if pressed, the front surface 101 is partially peeled off. As a result, there is no such deformation and stable waterproofness is maintained.
[0033]
In addition, since the protective sheet 102 is flexible, has a resilience, and is elastic, the inside of the casing is not affected even if the front casing 101 is deformed as shown in FIG. Since it is placed in a stable sealed state and the contact surface of the protective sheet 102 with the front housing 101 is formed to be thicker than other portions, the sealing performance is further improved.
[0034]
Next, another embodiment of the present invention will be described.
[0035]
FIG. 3 is a cross-sectional view showing the main configuration of a second embodiment of the information processing apparatus according to the present invention.
[0036]
In this embodiment, in addition to the structure of the embodiment shown in FIG. 1, a touch panel 301 is provided by utilizing the characteristic that the protective sheet 102 has flexibility. Since the other configuration is the same as that of the embodiment shown in FIG. 1, the same reference numerals as those in FIG.
[0037]
In this embodiment, the image display unit 103 is used as a display unit used with the touch panel 301. As in the case of the first embodiment, the support member 105 keeps the distance between the protective sheet 102 and the touch panel 301 at about 0.5 mm and prevents Newton rings from occurring.
[0038]
As the protective sheet 102 in this embodiment, a material excellent in heat resistance, cold resistance, weather resistance, and chemical resistance is suitable considering the spot life and water resistance. In this embodiment, a hard coating is applied to the surface of the polyester. The coated one is used. However, there is no particular limitation as long as the hit point life and water resistance are satisfied.
[0039]
FIGS. 4A and 4B are diagrams illustrating a state at the time of input according to the present exemplary embodiment, in which FIG. 4A illustrates a pressed state, and FIG. 4B illustrates a state after input in which the pressed state is released. Since the protective sheet 102 has flexibility and resilience, when the pen-shaped input member 401 is pressed, the protective sheet 102 is bent and input to the touch panel 301 is possible as shown in FIG. When the input member 401 is separated from the protective sheet 102 after the input is completed, the protective sheet 102 returns to its original shape as shown in FIG.
[0040]
As described above, in this embodiment, since the protective sheet 102 has flexibility and restorability, an information processing apparatus with a touch panel is realized. Since the input to the touch panel 301 is performed via the protective sheet 102, the touch panel 301 itself is very unlikely to have a keystroke, and the touch panel 301 is less likely to be replaced due to a keystroke. As a result, the maintenance cost is reduced when viewed from the user side, and the inventory amount of maintenance parts can be reduced when viewed from the manufacturing company side.
[0041]
Further, since the touch panel 301 to be used is arranged in a highly waterproof casing, it is not necessary to waterproof the surface, and the manufacturing cost can be reduced.
[0042]
In each of the above-described embodiments, the description has been given on the assumption that the constituent members are sealed by the front casing 101, the rear casing 104, and the protective sheet 102 combined with the front casing 101. In information processing devices such as the above, waterproofing and dustproofing at the image display surface and the input part are important, and parts that are difficult to touch outside air during actual use (for example, in models that are often used on the knee) It is good also as making the hole for heat radiation in the part which contact | abuts a knee when using. In such a case, dust or the like is unlikely to enter because the hole is formed in a portion that is difficult to touch, but even if it has entered, the structure of the present invention has a protective sheet and an image display unit. Alternatively, since the space between the touch panel and the touch panel is sealed, dust or the like does not enter the image display surface, and a stable image can always be displayed.
[0043]
【The invention's effect】
Since the present invention is configured as described above, the following effects can be obtained.
[0044]
Since a protective sheet with flexibility and resilience is used, there is no gap between the casing and the protective sheet even when the casing is deformed. It can be maintained for a long period of time, and there is an effect that a touch panel can be used.
