[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable electronic device such as a book-type portable computer, and in particular, a disk drive device such as a CD-ROM drive device and a circuit component are mounted inside the housing. The present invention relates to a structure for housing a circuit board.

[0002]

2. Description of the Related Art In the field of portable computers, which have conventionally been centered on characters and graphics, so-called multimedia moments for integrating and utilizing moving images and sounds are increasing.

Since images and voices handled by this multimedia have a huge amount of data as compared with character information, data are recorded using a large-capacity optical disk. Therefore, C that reads the data recently recorded on the optical disk is used.
Portable computers with a built-in D-ROM drive have been commercialized.

This CD-ROM drive device includes a disc storage portion including a turntable on which an optical disc is mounted,
And a disk drive unit for rotating the optical disk via the turntable. The disk storage section and the disk drive section are stacked and stored vertically inside a box-shaped casing.

Then, the size of the disk storage section is
Since the size is determined according to the diameter of the optical disc, the size of the disc storage portion may be larger than the disc drive portion depending on the diameter of the optical disc. In such a CD-ROM drive device, a step is formed in a portion defined by the lower surface of the disk storage portion and the side surface of the disk drive portion, and the stepped portion is covered by the casing.

[0006]

However, the conventional casing does not have a shape that follows the step below the disk storage portion, but is merely a rectangular box shape. Inside the casing, there is an unused and unused space in the portion corresponding to the step.

Therefore, even when the CD-ROM drive is incorporated in the housing, the above-mentioned useless space remains, so that the mounting efficiency inside the housing cannot be improved, especially in a portable computer. This is not desirable for models that require compact housing.

The present invention has been made in view of the above circumstances, and obtains a structure in which the dead space around the casing can accommodate the functional components inside the casing and the mounting efficiency inside the casing can be improved. Especially.

[0009]

To achieve the above object, a portable electronic device according to the present invention accommodates functional parts.
In addition, it is provided with a case having an opening formed therein and a disk drive device arranged inside the case.

The disk drive device supports the disk.
Disc storage compartment and smaller than this disc storage compartment
Disk drive unit with various shapes and storage of these disks
And a casing surrounding the disk drive unit . Pull the disc storage section onto the casing.
It is supported so that it can be taken out and put in and out through the opening in the above housing.
And the casing holds the disc storage
And the concave corresponding to the step defined by the disk drive section
And a recess of the casing inside the housing.
At least a part of the above functional parts is placed in the part corresponding to
It is characterized by being.

According to this structure, the concave portion of the casing is
The part can be effectively used as an installation space for functional parts.
Therefore, when the disk drive is placed inside the housing,
In addition, there is no useless space left inside the housing , and the mounting efficiency of the functional component can be improved accordingly.

Further, the support arms 130a and 130b have a shaft portion 135 fitted in the recess 132. Shaft 135
Is in contact with the upper edge 132a of the recess 132 so as to be slidable in the front-rear direction. Therefore, as shown in FIG. 17B, by pulling out the palm rest 91 toward the hand side,
The shaft portion 135 is connected to the upper edge portion 132a of the concave portion 132 and the front edge portion 12
When the front end portion of the palm rest 91 is pulled up in this state, the palm rest 91 rotates upward with the shaft portion 135 as a fulcrum, as shown in FIG. 17C. The hard disk drive device 15 and the battery housing portion 40 are exposed upward. Then, as shown in FIG. 2, the rotation of the palm rest 91 is stopped when the rear end portion of the peripheral wall 127 of the palm rest 91 comes into contact with the upper ends of the side walls 94a and 94b of the keyboard mounting portion 92.

Therefore, the palm rest 91 has a closed position for covering the hard disk drive device 15 and the battery accommodating section 40 from above, and the hard disk drive device 1 and the closed position.
5 and the keyboard accommodating portion 92 are rotatably supported by an open position that exposes the battery housing portion 40 and the battery housing portion 40 upward. Therefore, the battery pack 46 is designed to be taken in and out from above the housing 4 with the palm rest 91 being rotated to the open position.

When rotating the palm rest 91 from the open position to the closed position, first, the palm rest 91 is rotated downward, and the peripheral wall 127 of the palm rest 91 is placed on the upper end portion of the lower housing 7. Then, in this state, the palm rest 91 is slid backward toward the keyboard mounting portion 92. Then, the support arms 130a and 130b
Fits into the fitting portion 131. At this time, the shaft portion 135 is
Since the ridge 133 is passed over while slidingly contacting the upper edge portions 132a of the fitting portions 131a and 131b, it is possible to give a feeling of nodulation at this time and recognize that the palm rest 91 is slid to the closed position.

Since the palm rest 91 is an elongated one extending over the entire width of the housing 4, when the palm rest 91 is slid rearward, the left and right support arms 130a, 13 thereof are supported.
