Description of the Related Art In recent years, the technical innovation of portable computers has been remarkable, and applications to multimedia utilizing integrated video and sound have been expanding. This portable computer supporting multimedia is a CD that reads video data and sound data recorded on an optical disc.
-It has a ROM drive. The CD-ROM drive is housed inside a housing of a portable computer together with peripheral devices such as a floppy disk drive.

[0003] The housing includes a housing main body and an upper housing connected to the housing main body.
The housing body has a bottom wall and four front, rear, left and right peripheral walls rising from the edge of the bottom wall, and has a flat box shape that is open upward as a whole. Inside the housing body, a space for accommodating the main circuit board and a space for accommodating the peripheral devices and the CD-ROM drive device are secured. The circuit board is screwed to the bottom wall of the housing body in a posture parallel to the bottom wall, and peripheral devices and a CD-ROM drive device are electrically connected to the circuit board. The circuit board, peripheral devices, and CD-ROM drive are covered by the upper housing.

[0004] By the way, recent portable computers are being reduced in size in order to improve portability. For this reason, the mounting space inside the housing body tends to be more and more limited, and depending on the size of this mounting space, peripheral devices and CD-ROMs
It may be necessary to stack the driving device and the housing in the thickness direction of the housing main body.

At the same time, a part of the circuit board and a peripheral device or a CD-ROM
The driving device and the driving device have a positional relationship such that they overlap each other in the thickness direction of the housing main body, and a part of the circuit board may overhang on the peripheral device or the CD-ROM driving device.

[0006]

In the case where the peripheral device and the CD-ROM drive device are stacked and arranged on each other, the peripheral device or C which is located on the upper side is used.
The D-ROM drive can be taken out from the upper end of the housing main body by removing the upper housing from the housing main body.

However, in a state where the peripheral device or the CD-ROM drive device located on the upper side is removed,
