A driving device includes a holder (16) movably carried by a chassis (5)
and adapted for transporting a disc cartridge the holder holds between an insertion/ejection
position and a loading position, and an ejection lever (39) for ejecting
the disc cartridge from the holder (16). The driving device also includes
a slider (31) movable in a direction of inserting the disc cartridge into
the holder (16) and in a direction of ejecting the disc cartridge from the
holder. The slider causes the holder (16) to be moved to the loading position
when the slider is moved in the disc cartridge inserting direction, while causing
the holder (16) to be moved to the insertion/ejection position when the
slider is moved in the disc cartridge ejecting direction. The driving device also
includes a spring member (45) provided between the ejection lever (39)
and the slider (31) for biasing the ejection lever (39) in a direction
of ejecting the disc cartridge from the holder (16) and for biasing the
slider (31) in the disc cartridge inserting direction.
