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