PROBLEM TO BE SOLVED: To reduce the number of parts and the man-hours for assembly, to promote miniaturization and weight reduction and to prevent dust, which is sucked together with external air into a drive device, from being stuck and deposited on the objective lens of an optical pickup concerning a drive device capable of exchanging data between two media of an optical disk and a memory card with a single drive device. SOLUTION: The driving circuit for a disk drive unit 21, the driving circuit for a memory card drive unit 42 and the control circuit for exchanging data between an optical disk 2 and a memory card 3 by mutually controlling these two driving circuits 21 and 42 are mounted on a single circuit board 51. Furthermore, this device is provided with an exhaustion mechanism 81 for discharging dust which is sucked from a memory card slot 41 into a main body 11 of the drive device together with external air to the outside of the main body 11 of the drive device without allowing the dust flow into the disk drive unit 21. |
