Abstract

PROBLEM TO BE SOLVED: To provide a display part structure which simplifies the shape of a front panel and reduces the unit price of parts and an influence upon degradation of the sensitivity. SOLUTION: An LCD window 31 and a frame 11 are formed into one body, and a front panel 21 is provided with a hole for display window, and the periphery of the hole is formed like a plane because it is unnecessary to support the LCD window. This front panel 21 is attached onto the frame 11 with which the LCD window 31 is formed into one body, and a color sheet 4 is laminated on the front panel 21, thus a display part is assembled and constituted.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display structure of a card-type call receiver.

[0002]

2. Description of the Related Art FIG. 3 shows the appearance of a card-type portable paging receiver. A front panel 2 which also serves as an antenna is incorporated in a frame 1 formed by plastic molding. Although not shown, the front panel 2 is connected to a rear panel at an end face in the longitudinal direction of the housing.
A loop antenna is formed. Front panel 2
In FIG. 4, a hole for a display window is formed, and the periphery of the hole is squeezed to form a concave portion, as shown in the AA cross-sectional view in FIG. A transparent or translucent LCD window 3 is placed in the recess of the front panel 2, and then a color sheet 4 having a display window hole formed on the front panel 2.
Is affixed. The LCD window 3 has a structure protruding from a hole in the display window as shown in FIG.

[0003] As shown in the cross-sectional view of FIG. 4, the rear panel 5 is assembled to the frame 1 on the bottom surface.
The printed circuit board 6 is mounted thereon. The LCD unit 8 is mounted on the pedestal 7 directly below the LCD window 3, and the board 6 and the LCD unit 8 are connected by the connector 9. A color sheet 10 is attached to the bottom surface of the rear panel 5.

[0004]

According to the above-mentioned conventional display portion structure, the concave portion formed by the complicated drawing around the display window hole of the front panel 2 is relatively difficult in processing and sheet metal processing. This is a process that is difficult to achieve accuracy. However, the height of the concave portion of the squeezed panel is required to have strict accuracy, so the mold manufacturing cost is high,
There is a drawback that the number of man-hours required for squeezing is increased and the unit cost of parts is increased.

[0005] The LCD unit 8 is one of the noise sources causing deterioration of the sensitivity. If the front panel 2 which also functions as an antenna has a concave portion, the front panel 2 is attached to the LCD unit 8. There is a drawback that the receiver comes close and the noise is picked up and the receiver sensitivity deteriorates.

SUMMARY OF THE INVENTION It is an object of the present invention to suppress the increase in the unit cost due to the formation of the concave portion in the front panel, which is a conventional problem, and to reduce the sensitivity deterioration due to the concave portion formed in the front panel. To provide a display unit structure that can reduce the effects of unit cost and sensitivity degradation by simplifying the above.

[0007]

An object of the present invention is to provide a receiver frame in which an LCD window and a frame are integrally formed, and mount a front panel also serving as an antenna having a hole for an LCD display window on the frame. It is further achieved by attaching a color sheet on the front panel.

[0008] Another object of the present invention is to provide a transparent material for an LCD window.
This is achieved by providing a receiver frame in which the frame is integrally formed by two-color molding using an opaque material.

According to the above means, since the LCD window is formed integrally with the frame, it is not necessary to form a concave portion for supporting the LCD window on the front panel, and the inner periphery of the hole opened for the LCD window is formed in a flat shape. In addition, the shape can be simplified only by linear processing. Further, since the front panel is mounted on a frame and a color sheet is attached thereon, the distance between the front panel and the LCD unit is increased, and the influence of noise generated from the LCD unit is reduced. In addition, a hole for an LCD window that does not require a recess in the front panel can be formed large, and the opening area as a loop antenna increases, thereby improving sensitivity.

Further, since the frame and the LCD window are integrally formed by two-color molding, a transparent material can be used for the LCD window and an opaque material can be used for the frame, so that a conventional design can be applied.

[0011]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a sectional view of a display unit structure according to an embodiment of the present invention. In the figure, the same symbols as those in FIG. 4 indicate the same parts.

The frame constituting the housing of the present invention is LC
The D window 31 and the frame 11 are integrally formed.
As the molding material, plastic molding is performed using a transparent or translucent material such as polycarbonate. Although a hole slightly larger than the LCD window 31 is formed in the front panel 21 for the display window, it is not necessary to support the LCD window 31, so that the periphery of the hole can be formed flat. The front panel 21 is mounted on the frame 11 on which the LCD window 31 is integrally formed, and the color sheet 4 is attached on the front panel 21 to assemble and configure.

As described above, since the LCD window 31 is integrated with the frame 11 in the present embodiment, the front panel 21 does not need a concave portion for supporting the LCD window, and
The periphery of the hole formed in the window 31 is formed in a flat shape, and the shape is simplified. For this reason, squeezing processing is not required, and processing is easy only by linear processing, and the cost of parts is reduced. In addition, since the recess formed in the direction of the LCD unit inside the front panel is eliminated, the front panel 21
The distance between the LCD unit 8 and the LCD unit 8 is increased, and the effect of noise generated from the LCD unit 8 can be reduced. Moreover, there is no concave portion for supporting the LCD window of the front panel 21 and the area of the hole formed for the display window is increased, and the effect of improving the sensitivity by increasing the opening area as the loop antenna is obtained.

FIG. 2 is a sectional view of a display unit structure according to another embodiment of the present invention.

The frame 111 and the LCD window 3 of this embodiment
11 is not a skeleton type, and the LCD window 311 is made of a transparent material (for example, acrylic or the like).
Is integrally molded by two-color molding using an opaque material (for example, polycarbonate or the like). On the integrally formed frame 111, a front panel 21 in which a hole for a display window is similarly formed is attached, and the color sheet 4 is attached thereon to assemble.

According to the two-color molding, a transparent material can be used for the LCD window 311 and an opaque material can be used for the frame 111 arbitrarily.

[0018]

As described above, according to the present invention, the shape of the front panel is simplified, the yield is improved, and the cost is reduced. Further, the distance between the front panel and the LCD unit is increased, and the influence of noise from the LCD unit is reduced. In addition, the sensitivity is improved due to the increased aperture area as the loop antenna. Also, assembling can be facilitated by reducing the number of parts by integrally molding the LCD window and the frame. By integrally molding the LCD window and the frame by two-color molding, a conventional design or an arbitrary design can be applied.
