In a disc cartridge, when a shutter fitting portion disposed at the outside of
a case is pressed, a shutter drawing portion is drawn to rotate an arcuate guide
wall portion together with a shutter main body. The shutter drawing portion is
swingable in the width direction of the arcuate guide wall portion, and thus occurrence
of component force for inclining the shutter main body due to the pulling of the
shutter drawing portion can be suppressed. Therefore, a first shutter member is
smoothly rotated, and an aperture for access to a disc medium is opened. According
to the present invention, there is provided a disc cartridge in which a shutter
member for opening/closing an aperture for access to a disc medium housed therein
can operate smoothly.
