Description

  The present invention relates to an electronic device, and more particularly to a portable electronic device such as a mobile phone.

2. Description of the Related Art In recent years, mobile phones are widely used in which two housings are attached so as to be openable and closable for the purpose of downsizing. In such a cellular phone, in order to detect the open / closed state of these casings, for example, a detecting means in which a magnet and a hall element are arranged to face each other is attached in each casing (see Patent Document 1). Such a component cannot be installed on a substrate attached in the housing due to its nature, and is thus attached to the position avoiding the substrate on the inner surface of the housing with an adhesive or the like.

Furthermore, a receiver 15 that outputs a received audio signal is attached to the front end side of the box portion 5. The receiver 15 is fixedly arranged so as to face an opening (not shown) provided on the bottom surface of the box portion 5.
Although not shown, a substrate is mounted between the LCD reinforcing plate 10 and the lid portion 6.

  In the method of assembling the mobile phone 1 having the above-described configuration, the LCD 9 and the LCD reinforcing plate are mounted so that the magnet 11 is mounted on the component mounting portion 8c from the outside of the opening 8b and the outer surface of the mounted magnet 11 is closed. 10 is attached to the box part 5. Specifically, the cellular phone 1 is assembled in the following procedure.

First, the magnet 11 is mounted on the component mounting portion 8c provided on the wall portion 8 of the box portion 5 in the direction from the inner side in the width direction of the box portion 5 to the outer side (the direction indicated by the arrow in FIG. 2). And the protective material 5a is affixed on the periphery of the bottom upper part of the box part 5. FIG.
Thereafter, the LCD 9 is placed in the box portion 5 so that the periphery of the LCD 9 is placed on the protective material 5a in a fixed state except for the direction in which the opening portion 8b faces so that the magnet 11 does not fall off the component mounting portion 8c. Attach to. Then, the LCD reinforcing plate 10 is mounted on the box portion 5 so as to abut on the upper portion of the LCD 9 while inserting the protruding portion 10 c of the LCD reinforcing plate 10 into the notch portion 8 d of the wall portion 8. At this time, the side surface in the longitudinal direction of the LCD 9 is covered with the side plate portion 10 b of the LCD reinforcing plate 10, and a part of the side plate portion 10 b closes the opening portion 8 b of the wall portion 8 to It will be positioned to hold down.

After the LCD 9 and the LCD reinforcing plate 10 are mounted on the box portion 5, the receiver 15 is attached to the distal end side of the box portion 5, and the imaging unit 12 and the two acoustic speakers 13 are attached to the proximal end side of the box portion 5. Then, the operation unit 14 is attached to the shaft portion 12 a of the imaging unit 12, and the operation unit 14 is disposed at a predetermined position on the proximal end side of the box unit 5.
Thereafter, the substrate is mounted so as to be placed on the LCD reinforcing plate 10. And the cover part 6 is attached to the box part 5 so that these components mounted | worn in the box part 5 may be covered, and the assembly of the 1st housing | casing 2 is completed.
Thereafter, the second casing 3 is attached to the first casing 2 so as to be rotatable by the hinge portion 4, and the assembly of the mobile phone 1 is completed.

  In the mobile phone 1, since the magnet 11 is a magnetic material, it affects other parts due to the magnetic force, so that the placement on the substrate must be avoided. Therefore, it is necessary to arrange at a position different from the substrate. Therefore, as described above, the wall portion 8 is provided in the box portion 5 of the first housing 2, and the component mounting portion 8c having the opening 8b is provided in the wall portion 8, so that the magnet is provided in the component mounting portion 8c. If 11 is installed, it is not necessary to secure a special space for arranging the magnet 11. Accordingly, since there is no hindrance to the arrangement of the magnets 11 that cannot be mounted on the substrate, space saving of the mobile phone 1 including the first housing 2 can be achieved.

Further, when the LCD 9 and the LCD reinforcing plate 10 are attached to the box portion 5, the side plate portion 10b of the LCD reinforcing plate 10 is disposed at a position that closes the opening portion 8b, so that the magnet installed in the component mounting portion 8c. 11 is pressed and fixed to the side plate portion 10b. Thereby, the process of adhering the magnet 11 to the box part 5, that is, the process of applying an adhesive to the magnet 11 and attaching the magnet 11 to the box part 5 and drying it for a predetermined time becomes unnecessary. Therefore, the man-hours for assembling the magnet 11 can be reduced.
Moreover, since the process of adhering the magnet 11 to the box part 5 is not required in this way, an adhesive is not used, so that the problem of falling off the box part 5 of the magnet 11 due to deterioration of the adhesive can be solved. .

In the above embodiment, the magnet and the LCD are used as the components. However, the present invention is not limited to these, and other components may be used.
Further, in the above embodiment, when assembling the mobile phone 1, the assembly procedure shown above may be moved back and forth as long as the mobile phone 1 can be assembled.
In the above embodiment, the LCD reinforcing plate 10 may not be provided. In this case, the side surface of the LCD 9 is disposed so as to close the opening 8b, and the magnet 11 mounted in the component mounting portion 8c is pressed and fixed.
In the above embodiment, the component mounting portion 8 c is not limited to being attached to the box portion 5, but is partially or partially depending on the components provided in the first housing 2 or the second housing 3. All may be configured.
