[0002]

2. Description of the Related Art In a portable electronic device such as a notebook personal computer, a word processor, a digital video camera, a portable game machine, an electronic organizer or a calculator, a lid having a display screen has a main body in which components are mounted. It is attached to the part by a hinge shaft so that it can be opened and closed freely. The hinge axis is fixed to the main body, and the lid is opened and closed with the hinge axis as a central axis. For example, in the case of a notebook computer as shown in FIG. 10, as shown in FIG. 11, the cover 10 has recesses at two positions on the side where the hinge shaft (not shown in FIGS. 10 and 11) is arranged. 10a are provided, and the main body 50 has two protrusions 50a fitted into the recesses 10a at two positions on the side where the hinge shaft is disposed.
Is provided.

The lid 10 has a liquid crystal display panel 16 sandwiched between a flat rear panel 12 and a frame-shaped front panel 14. The rear panel 12 and the front panel 14 are provided with an outer peripheral portion that is formed by bending the periphery of a flat plate portion, and the outer peripheral portions are joined together to be integrated.

The display panel 16 is fitted in a frame 20 as shown in FIG. 12A which is an enlarged view of a portion X in FIG. 11, and the frame 20 is held by a stay 22.
Two bosses 1 are provided at the corners of the flat plate portion of the back panel 12.
2a and 12b are formed. The outer boss 12a has a joint 22a formed by bending the tip of the stay 22 at a right angle.
Are fixed by screws 100.

The end of the hinge shaft 32 is fixed to the inner boss 12b. At the end of the hinge shaft 32, flat portions 32a and 32b parallel to the lower side and the upper side are formed, and the lower flat portion 32a and the inner boss 12b are joined, and a screw 1 is formed.
00, the end of the hinge shaft 32 is fixed to the boss 12b. An intermediate portion of the hinge shaft 32 has a columnar shape and penetrates the concave portion 10a of the lid portion 10. A round hole is formed in the concave portion 10a of the lid 10 through which the hinge shaft 32 passes, so that the lid 10 can be opened and closed about the hinge shaft 32 as a central axis.

On the other hand, as shown in FIG.
The lower housing 52 and the upper housing 54 are combined, and a substrate 60 on which electronic components (not shown) are mounted is disposed between the lower housing 52 and the upper housing 54. As shown in FIG. 10, the upper housing 54 is provided with an input unit 51 including a large number of keys and the like (not shown). At the corners of the lower housing 52 and the upper housing 54, continuous bosses 52a and 54a are provided.
“a” sandwiches the end of the substrate 60. The boss 52a of the lower housing 52 is provided with a deep hole 52c, and the boss 54a of the upper housing 54 is formed with a female screw. 5
2. The upper housing 54 and the substrate 60 are integrally fixed.

[0007] The lower housing 52 is provided with ribs 52b for positioning components 70 such as a floppy disk drive and a CD-ROM drive. In this specification, the substrate 60 and the component 70

And ribs 52b are formed. Lid 10 or body 50
Are formed by pressing a sheet metal, the bosses 12a, 12b, 52a, 54a and the ribs 52b
Is difficult to form integrally. Therefore, the main body 50 and the lid 10 are formed by injection molding using a resin material, die casting or thixomolding using a metal material such as magnesium, or the like.
2b, 52a, 54a and rib 52b are integrally formed.

However, since the resin material has a smaller elastic modulus than the metal material, the resin lid 10 and the main body 50 need to have a certain thickness in order to obtain high rigidity. And the main body 50 cannot be made sufficiently thin. Furthermore, the lid 10 and the main body 50 made of resin must be provided with a heat radiating means and an electromagnetic shield, and there is a problem that the cost increases due to an increase in the cost of parts and the number of assembling steps.

On the other hand, the bosses 12a, 12b,
In order to integrally mold the 52a, 54a and the rib 52b, there is a limit in reducing the thickness of the lid 10 and the main body 50 due to manufacturing restrictions, and it is not possible to sufficiently reduce the weight of the electronic device. However, there is a problem that costs are increased due to poor productivity.

An object of the present invention is to provide an electronic device mounting structure in which a lid is mounted on a main body by a hinge shaft, and the electronic device mounting structure is reduced in thickness, weight, and productivity. Aim.
