DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a button structure in a portable radio device.

[0002]

2. Description of the Related Art As shown in FIG.
, A pair of cylindrical projections 20 are integrally provided by resin molding,
The button 15 is formed by providing a hole 19 having a position and a size corresponding to the protrusion 20 at the end of the arm portion 18 extended to the extent that the button key 16 can be elastically deformed. At the time of assembly, the projection 20 of the housing case 22 is passed through the hole 19 of the button. At this time, it is necessary that the height of the projection 20 be somewhat higher than the thickness around the hole 19. After assembling the button 15, the upper end of the projection 20 was heated and deformed by specific equipment and fixed by welding. When the display or mark 23 is provided on the outer surface of the button key 16 as shown in FIG. 3B, the display or mark 23 is printed or hard colored differently from the button key 16. The button key 16 was formed integrally with the general resin material 17.

In the above-described conventional housing and button structure, there is a problem that the display or mark on the button external surface cannot be recognized in a dark place. In this case, there is a method of causing the display or the mark portion to emit light by using an electric illuminating means such as an LED.
This is not a good measure for portable wireless devices whose consumption current increases and prices are decreasing.

Further, in a conventional portable wireless device, a device based on vibration is often used as a means for notifying of an incoming signal. However, at a contact portion with an internal switch of the device, vibration of a button key made of a hard general resin material is performed. Caused noise. In this case, there is a method of molding the entire button with soft silicone rubber. However, there is a problem that the touch and the appearance quality at the time of button operation degrade the high-grade appearance of the portable wireless device.

SUMMARY OF THE INVENTION In view of the drawbacks of the prior art, an object of the present invention is to improve the visibility of a button or mark in a dark place, and to provide a button and a housing structure which are not affected by vibrations without deteriorating a high-quality view. To provide

Next, the present invention will be described with reference to the drawings.

FIG. 1 is an exploded perspective view showing an embodiment of the present invention, FIG. 2A is an external perspective view of a portable wireless device in the embodiment, and FIG. 2B is a view in FIG. It is sectional drawing at the time of cutting | disconnection by the AA line.

First, a description will be given of a housing structure of a portable wireless device on which the present embodiment is based. A pair of projections 7 are formed integrally with the inner wall of the housing case 8 by resin molding at appropriate intervals, and a concave portion 11 is provided between the projections 7. The housing case 8 has a rectangular parallelepiped shape of the button 1 or a substantially cylindrical shape. An opening 9 is provided so that the button button 3 having a shape can be pressed and moved. One end of the arm portion 5 extended to the extent that the button key 3 of the button 1 is elastically deformed, a protrusion 6 having a T-shaped cross section slightly wider than the gap between the protrusions 7 and a protrusion 6 at one end of the arm 5. The plate-like rib 6a is integrally formed by resin molding so as to protrude from the width and abut against the pair of protrusions 7 when the button 1 is assembled into the housing case 8. Note that a liquid crystal display unit 10 for displaying the transmitted information is provided on the surface of the housing case 8.

Here, a display or mark 12 as shown in FIG. 2A is provided on the external surface of the button 1. The configuration of the button 1 in this embodiment in this case will be described below.

At the button 1, the display or mark 1
2. Contact part 2 and switch 4 with switch 13 inside the device
Is injection molded with a soft luminous resin material. As the phosphorescent resin material, an elastomer can be used, and specifically, Pandex T-1690 (manufactured by Dainippon Ink and Chemicals, Inc.)
Can be used. The operating portion 4 has a display or mark 12 on the outer surface exposed from the housing case 8, while the contact portion 2 for operating the switch 13 is provided on the opposite surface.
Having. On the other hand, the arm 5, the protrusion 6, and the plate-like rib 6a of the button 1 are formed of a general resin material such as a hard polycarbonate resin. Specifically, Panlight L
-1225Z (manufactured by Teijin Chemicals Ltd.) can be used. Therefore, the button 1 is integrally molded (usually referred to as two-color molding) of different kinds of resins.

In this embodiment, the vibrator 14 which operates in a dark place and notifies an incoming call by vibration.
The operation at the time of vibration will be described. Since the display or mark 12 on the external surface of the button 1 is formed of a phosphorescent resin material, it emits light for a certain period of time in a dark place, and the display or mark 1
2 improves the visibility and operability. In addition, since the display or mark 12 is integrally formed by resin molding, manufacturing defects such as printing position shift and printing bleeding, which tend to occur in secondary processing such as printing, do not occur. Further, since the luminous resin material is a rubber-like soft material, it is possible to greatly reduce the level of noise that occurs when the vibrator 14 vibrates and the contact portion 2 generates a minute vibration between the contact portion 2 and the switch 13.

[0013]

As described above, according to the present invention, when a radio signal is received, an incoming call is notified by the sound or vibration of a vibrator, the transmitted information is displayed on a liquid crystal panel, and a portable device having operation buttons on the front of the device. In the radio equipment for wireless communication, only the contact part between the display or mark of the operation button and the switch inside the device and the operating part are made of soft rubber-like injection-moldable luminous resin material, and the other parts are hard general resin. The following effects can be obtained because they are integrally formed of a material.

(1) The display or mark on the button external surface is recognizable in a dark place and has good operability, and is compared with a conventional method in which the display or mark portion emits light using an electric illuminating means such as an LED. This is a very good means for a portable wireless device whose cost is reduced due to reduction in the number of parts and current consumption.

(2) Even if the means for notifying the arrival of a signal is due to the vibration of the vibrator, no noise due to vibration is generated at the contact point with the internal switch of the device, and the conventional method of molding the entire button with soft silicon rubber. Compared with the above, the touch and appearance quality at the time of button operation do not impair the high-grade appearance of the portable wireless device.
