In the figure, the same reference numerals as those in FIG. 10 denote the same or corresponding parts, and a description thereof will be omitted. In the figure,
Reference numeral 100 denotes a coil spring, one end of which is connected to a lower portion of one end of the base member 4 and the other end of which is connected to the outer frame of the disk device 1 to urge one end of the base member 4 upward. Also,
The biasing force of the coil spring 100 is the largest at the table standby position in FIG. 1A, and is adjusted to be substantially the same as the moment of one end of the base member 4 at the disk drive position in FIG.

Next, the operation of raising one end of the base member 4 from the table standby position in FIG. 1A to the disk drive position in FIG. 1B will be described. When raising one end of the base member 4 from the table standby position in FIG. 1A to the disk drive position in FIG. 1B, the motor 6 shown in FIG.

Is applied, one end of the base member 4 can be raised even if the driving force of the motor 6 itself is small, so that a small motor having a small driving force can be used and the disk device 1 can be downsized. Further, since an inexpensive motor having a small driving force can be used, the manufacturing cost of the disk device 1 is reduced.

Next, the operation of lowering one end of the base member 4 from the disk drive position in FIG. 2B to the table standby position in FIG. 2A will be described.
