Application No. 08/896,533
Claim 1, which is representative for present purposes,
follows:
1. A shutter mechanism for a disk cartridge
insertion opening of a disk drive device, said
shutter mechanism comprising:
a shutter leaf swingably mounted in said
opening, said shutter leaf being swingable about a
swing axis both inwardly towards an inner position,
and outwardly towards an outer position, with
respect to said disk drive device, and having a
length in a direction perpendicular to said swing
axis which is shorter than a dimension of said
insertion opening in said direction to define a gap
between an end of said shutter leaf and an adjacent
peripheral surface of said insertion opening; and
at least one resilient skirt along at least a
portion of a periphery of said shutter leaf, said
resilient skirt extending toward and contacting said
adjacent peripheral surface of said insertion
opening so that said resilient skirt substantially
covers said gap between said shutter leaf and said
insertion opening when said shutter leaf is in a
closed position, said resilient skirt contacting
said peripheral surface when in the closed position
between said inner and outer positions.
