Function expansion device for a portable electronic device

摘要

A function expansion device is attached to a portable electronic device such as a notebook-type personal computer (40) so as to provide a function to use various kinds of information storage media. A bay housing (70) is detachably attached to a bottom surface of the notebook-type personal computer (40). The bay housing (70) has a bay (73) into which a drive unit is inserted. The drive unit can be selected from among a floppy disk drive (110), a CD-ROM drive (130), a magneto-optical disk drive (140), a high-capacity floppy disk drive (150), a hard disk drive (160) and a digital video disk (170). Each of the drive units has an identical outer configuration so that each of the drive units can be alternatively attached to the bay housing (70). Various types of drive units can be connected to the notebook-type personal computer by merely changing the drive unit accommodated in the bay housing (70). <IMAGE>
