2. Description of the Related Art In a portable terminal such as a portable telephone for exchanging information by communication, a pair of housings are rotatably connected about a rotation axis in a closed state where they are overlapped with each other and an open state where they are separated from each other. There is a folding type. This foldable mobile terminal has an LCD screen provided in one housing and operation keys arranged in the other housing. A large LCD screen is attached, and then folded when not in use to reduce the size. There are merits that can be done. Further, at the time of folding, the LCD screen and the operation keys are opposed to each other, so that they are arranged inside to protect them from external force, thereby providing an advantage of preventing breakage thereof.

[0003]

However, even in the above-mentioned foldable portable terminal, when carrying around in a bag or the like, for example, as shown in FIG. (Pointed pens, etc.)
50 is a pair of housings 51, 5 overlapping with some time signature
In some cases, it may enter between the two opposing surfaces 51a and 52a from the side. The formation of R at the corners on the side of the facing surfaces 51a and 52a also increases the possibility of such foreign matter 50 entering. Thus, the pair of housings 5
If the foreign matter 50 enters between the opposing surfaces 51a, 52a of the first and second components 52, 52, if any load is applied to the first and second components 51 and 52, the foreign matter 50 may be applied to the LCD screen, the first and second components 51 and 52, and further to internal electric components. In some cases, damage was caused.

Accordingly, an object of the present invention is to provide a portable terminal which is less likely to be damaged by preventing foreign matter from entering between opposing surfaces of the housings.

[0005]

In order to achieve the above object, a portable terminal according to the present invention is characterized in that a pair of housings are centered on one rotation axis in a closed state where they overlap each other and an open state where they are separated from each other. In a foldable portable terminal that is rotatably connected, the outer peripheral edge of one housing is overlapped with the other housing, and is located outside the outer peripheral edge of the other housing. It is characterized in that a rib-like projection protruding in the direction of the other housing is formed.

As described above, the outer peripheral portion of one housing is positioned outside the outer peripheral portion of the other housing in a state of being overlapped with the other housing, that is, the other housing is overlapped with the other housing. Since the rib-shaped protrusion protruding in the direction of the housing is formed, even if a foreign substance tries to enter between the opposing surfaces of the housing from the side, this can be prevented by the presence of the rib-shaped protrusion.

In this case, the rib-shaped convex portion is formed only on both edge portions of the one housing extending along a direction perpendicular to the rotation axis. Is also good.

According to this structure, the rib-shaped convex portion can be provided only in a portion where foreign matter is particularly likely to enter, so that an increase in weight can be minimized.

[0009] The rib-shaped projections may be provided at both ends of the one housing extending along a direction perpendicular to the rotation axis, and at opposite ends to the rotation axis. It is good also as a structure characterized by being formed in.

According to this structure, the rib-shaped projections are provided in all directions where foreign matter may enter, so that foreign matter can be reliably prevented from entering.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A portable terminal according to an embodiment of the present invention will be described below with reference to FIGS.

The mobile terminal 10 of the first embodiment is a so-called mobile phone capable of transmitting and receiving voice calls and mails. One pair of housings 11 and 12 is in a closed state where they are overlapped with each other and an open state where they are separated from each other. Is a foldable type that is connected to be rotatable about a rotation axis X.

The pair of housings 11 and 12 have a substantially rectangular plate shape connecting their edges to each other.
Is provided with an antenna 14. Also, for example, an operation key (not shown) is provided on the one housing 11 on a surface 11 a facing the other housing 12.
2 is provided with an LCD, for example, on a surface 12a facing one housing 11.
A screen (not shown) is provided.

One housing 11 has an outer peripheral edge in a direction perpendicular to its thickness direction, and the other housing 12
In a state where the other housing 12 overlaps with the other housing 12, a rib shape is located outside the outer peripheral edge in a direction orthogonal to the thickness direction of the other housing 12 and protrudes from the facing surface 11a in the direction of the other housing 12. The projection 15 is formed.

More specifically, the outer peripheral edges in a direction orthogonal to the thickness direction of one of the housings 11 and both end edges extending along a direction orthogonal to the rotation axis X (see FIG. 2) Left and right edge portions) protrude outward from the other housing 12, and only these protruding portions overlap with the other housing 12 in the direction of the other housing 12 in a state of overlapping with the other housing 12.
A rib-shaped convex portion 15 protruding from a is formed. Note that the rib-shaped convex portion 15 is provided between the one housing 11 and the other housing 1.
In a state where the second housing 12 and the second housing 12 overlap with each other, the height of the second housing 12 exceeds the facing surface 12a.

According to the portable terminal 10 having such a configuration,
The outer peripheral edge in the direction orthogonal to the thickness direction of the one housing 11, specifically, the outer peripheral edge in the direction orthogonal to the thickness direction of the one housing 11 and the rotation axis X
The other housing 1 is overlapped with both ends extending along a direction orthogonal to the outside of the outer peripheral edge of the other housing 12 in a state of overlapping with the other housing 12.
Since the rib-shaped convex portion 15 protruding in the direction 1 is formed, foreign matter 17 such as a pen enters the space between the opposing surfaces 11a and 12a of the housings 11 and 12 from the side as shown in FIG. The existence of the rib-shaped projections 15 can prevent this.

Therefore, it is possible to prevent the foreign matter 17 from entering, so that the LCD screen, the housings 11 and 12 and the internal electric parts are hardly damaged.

Moreover, the rib-shaped convex portion 15 is connected to one of the housings 1.
1, the outer peripheral edge in the direction perpendicular to the thickness direction and formed only at both end edges extending along the direction orthogonal to the rotation axis X, so that the foreign matter 27 is particularly easy to enter. Only the rib-shaped convex portion 15 can be provided,
Weight gain can be minimized.

In the above description, the rib-shaped projection 15
Has been described as an example in which only one of the two housings 11 is formed on the outer peripheral edges in the direction perpendicular to the thickness direction and both ends extending along the direction perpendicular to the rotation axis X. Are formed by forming a rib-shaped convex portion on one housing 11 at the outer peripheral edge portion in a direction perpendicular to the thickness direction and extending at both end edges extending along a direction perpendicular to the rotation axis X and the rotation axis. X
May be formed on the opposite edge. in this case,
The rib-shaped protrusions formed on both end edges extending along the direction orthogonal to the rotation axis X and the rib-shaped protrusions formed on the end edge opposite to the rotation axis X are made continuous. It is also possible.

As described above, the rib-shaped projection is connected to one of the housings 1.
1, the outer peripheral edge in the direction orthogonal to the thickness direction and formed at both end edges extending along the direction orthogonal to the rotation axis X and the edge opposite to the rotation axis X if,
By providing the rib-shaped protrusions in all directions where foreign matter may enter, it is possible to reliably prevent foreign matter from entering.

In the above description, the case where the rib-shaped convex portion is provided on the housing 11 on which the operation keys are provided has been described as an example. Of course, the rib 12 is provided on the housing 12 on which the LCD screen is provided. A convex shape may be provided.

[0022]

As described above in detail, according to the portable terminal of the present invention, the outer peripheral edge of one housing is overlapped with the outer peripheral edge of the other housing. Since the rib-shaped convex portion protruding in the direction of the other housing is formed outside, that is, overlapped, even if foreign matter tries to enter between the opposing surfaces of the housing from the side, This can be prevented by the presence of the rib-shaped protrusions. Therefore, it is possible to prevent a foreign substance from entering, and it is possible to make the structure hard to be damaged.

In this case, if the rib-shaped protrusions are formed only on both end edges of one of the housings extending along a direction perpendicular to the rotation axis, the rib-shaped protrusions are formed only on portions where foreign matter is particularly likely to enter. Protrusions can be provided, and increase in weight can be minimized.

Further, the rib-shaped convex portions may be formed at both ends of one of the casings extending along a direction perpendicular to the rotation axis and at an end edge opposite to the rotation axis. Since the rib-shaped projections are provided in all directions where foreign matter may enter, foreign matter can be reliably prevented from entering.
