DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a holding structure for a liquid crystal panel and a portable terminal device using the holding structure, and more particularly to a structure for holding a liquid crystal panel which is stored in a portable telephone and displays information.

[0002]

2. Description of the Related Art FIG. 3 is a perspective view of a portable telephone. The mobile phone is a first cabinet (1) equipped with a transparent plate (10).
And a second cabinet (2) provided with an operation button (20) are connected by a hinge part (7) and provided so as to be foldable. FIG.
FIG. 4 is a cross-sectional view of FIG. 3 cut along a plane including the line AA. The first cabinet (1) has two synthetic resin cabinet halves (3) and (3) butted together, and bosses (30) and (30) projecting inward from both cabinet halves (3) and (3). The screw
(6) Stopped and configured. Upper cabinet half (3)
Is provided with an opening (31), and the transparent plate (10) covers the opening (31). In the cabinet (1), chip components (80) (8
0) is accommodated, and the circuit board (8)
One end of (8) is fitted between the bosses (30) (30). On the circuit board (8), below the transparent plate (10), there is provided a liquid crystal panel (5) for indicating a call state and the like, and information displayed on the liquid crystal panel (5) is transmitted to the transparent plate (10). Can be seen through.
The periphery of the liquid crystal panel (5) is surrounded by a frame (4) made of synthetic resin.

In recent years, mobile phones have been demanded to be thinner. In the structure shown in FIG. 4, a circuit board (8) and chip components (80) (80)
Thicker In view of this point, as shown in FIG. 5, the liquid crystal panel (5) is directly mounted on the cabinet half (3), and a flexible circuit board (not shown) provided in the second cabinet (2) is used. (81) is connected to the liquid crystal panel (5) to supply power.

[0004]

Although the structure shown in FIG. 5 can achieve a reduction in thickness, the strength of the first cabinet (1) is weak, and when the first cabinet (1) is twisted, the liquid crystal panel (5) is broken. Or cracks may occur. In view of this point, the applicant has conceived of forming the frame (4) of the liquid crystal panel (5) from a metal, specifically, an aluminum or magnesium alloy.
Since the metal frame (4) has high rigidity, the liquid crystal panel
Although it was effective in preventing cracking of (5), the first cabinet
When (1) is twisted, there remains a problem that the liquid crystal panel (5) inadvertently moves horizontally in the first cabinet (1). In this case, every time the first cabinet (1) is twisted, the information display position of the first cabinet (1) shifts. An object of the present invention is to achieve a thin cabinet and prevent a liquid crystal panel from inadvertently horizontally moving in the cabinet.

[0005]

Means for Solving the Problems A pair of cabinet halves
(3) Cabinet constructed by fixing (3) with screws (6)
In the structure for holding a frame (4) surrounding a liquid crystal panel (5) in (1), the two cabinet halves (3) are separated from the frame (4).
A tongue piece (40) which is sandwiched between (3) and has a hole (41) into which the screw (6) fits is projected. The frame (4) is made of metal.

[0006]

[Operation and Effect] The tongue piece (40) of the frame (4) is sandwiched between the two cabinet halves (3) and (3), and the screw (6) is fitted therein. Thereby, even if the first cabinet (1) is twisted,
(4) is prevented from inadvertently horizontally moving inside the first cabinet (1), and the information display position of the first cabinet (1) is prevented from shifting. The tongue piece (40) is fastened together with screws (6) necessary to fasten both cabinet halves (3) and (3), and the components for fixing the frame (4) are as follows. Does not increase.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an example of the present invention will be described in detail with reference to the drawings. The overall configuration of the mobile phone is the same as the conventional configuration shown in FIG. 3, and this embodiment is characterized in that the information display position of the first cabinet (1) is prevented from shifting. FIG.
2 is a plan view of the lower cabinet half (3), and FIG.
FIG. 2 is a sectional side view of the first cabinet (1). As in the prior art, the first cabinet (1) is formed by abutting two cabinet halves (3) and (3) made of a synthetic resin, for example, PC (polycarbonate) and an alloy material of ABS, so that both cabinet halves are joined together. Bosses (30) (30) projecting inward from the bodies (3) (3) are screwed (6). The periphery of the liquid crystal panel (5) is made of metal, specifically an aluminum frame
The tongue pieces (40), (40), (40), (40), which are surrounded by (4) and have holes (41), project outward from the corners of the frame (4).
Since the frame (4) is made of metal, the rigidity is high, and even if the first cabinet (1) is twisted, the liquid crystal panel (5) is not damaged.

The upper cabinet half (3) has an opening (3
1) is provided, and the opening (31) is covered with a transparent plate (10). The liquid crystal panel (5) is provided below the transparent plate (10). The tongue piece (40) is sandwiched between the bosses (30) (30), and the screw (6) fitted to both bosses (30) (30) passes through the hole (41) of the tongue piece (40). As a result, the horizontal movement of the liquid crystal panel (5) inadvertently in the first cabinet (1) is restricted, and even if the first cabinet (1) is twisted, the information display position of the first cabinet (1) is prevented. Deviation is prevented. The tongue piece (40) is fastened together with screws (6) necessary to fasten both cabinet halves (3) and (3), and the components for fixing the frame (4) are as follows. Does not increase.

As described above, it is necessary to make the first cabinet (1) thinner, and it is desirable that the tongue piece (40) be as thin as possible. Since the frame (4) is made of metal, the tongue piece (40) can be cut and thinned. If the frame body (4) is made of resin, the frame body (4) is generally formed by injection molding. In the case of such injection molding, when the tongue piece (40) is thin, the molten resin is formed by the tongue piece ( There is a possibility that the portion where (40) is formed cannot be sufficiently filled. Therefore, the reason why the frame 4 is made of metal is not only to increase the rigidity but also to make the tongue piece 40 thin.

Further, there is a case where both cabinet halves (3) and (3) are formed of a metal such as magnesium, and the metal cabinet halves (3) and (3) are resin cabinet halves. (3) Since the rigidity is higher than that of (3) and it is hardly deformed even when twisted, it seems to be effective in preventing the information display position of the first cabinet (1) from shifting. However, the applicant did not adopt the metal cabinet halves (3) and (3) for the following reasons. To form a metal cabinet half (3) (3), use a cabinet half (3)
In view of the complexity of the shape of (3), it is generally provided by injection molding a molten metal. FIG. 6 is a sectional view of a mold for injection molding. As is well known, the mold includes a fixed mold (9) and the fixed mold (9).
A movable mold (90) that abuts (9) is provided, and a space S between both molds (9) and (90) is filled with molten metal from a gate (not shown),
Obtain cabinet halves (3) and (3). However, both types (9) (9
If there is a slight gap in the abutting surface of (0), molten metal enters the gap and generates burrs. Half cabinet (3)
If (3) is made of resin, this burr can be easily removed, but since it is made of metal, it takes time to remove the burr. That is, the manufacturing cost of the cabinet halves (3) and (3) increases,
The yield when mass-producing the cabinet halves (3) (3) is also reduced. In this respect, the applicant has
(3) (3) was made of synthetic resin. The holding structure of the liquid crystal panel shown in this example is not limited to use in a mobile phone, but can be applied to other mobile terminal devices, such as a digital still camera. Although four tongue pieces (40) are provided, the number is not limited to four.

The description of the above embodiments is for the purpose of illustrating the present invention, and should not be construed as limiting the invention described in the appended claims or reducing the scope thereof. Further, the configuration of each part of the present invention is not limited to the above-described embodiment, and it is needless to say that various modifications can be made within the technical scope described in the claims.
