First Claim
Patent Images
1. An air filtration system for collecting dust in a sealed casing which houses a rotating disk-type data recording medium, said system comprising:
- an elastic holding member;
a substantially planar filter member;
said sealed casing having means for supporting said elastic member peripherally adjacent the outer edge of said disk-type medium so that the plane of said filter member extends substantially in a direction of the radius of said disk-type medium, and further extends with the plane of said filter member disposed substantially orthogonal to the plane of the disk-type medium.

Abstract
A disk drive which removably holds a filter member for air filtration system by an elastic member being fixed in a casing housing a disk-type data recording medium, so that its constitution can be simplified and process of assembling and mounting it in the sealed casing can be minimized.

- 10. An air filtration apparatus for collecting dust in a sealed casing of a disk drive apparatus which houses a rotating disk-type data recording medium, said air filtration apparatus comprising, a filter member, a holder for removably receiving and retaining said filter member, said holder comprising an elastically deformable member having opposed surfaces, said holder assuming a first position in which said opposed surfaces are separated to receive said filter member therebetween and a second position in which said opposed surfaces are disposed in close proximity to each other so as to nip and maintain said filter member therebetween, and means for slidably receiving said holder in said sealed casing adjacent said disk-type data recording medium and for maintaining said holder in said second position.

20. An air filtration apparatus for collecting dust in a sealed casing of a disk drive apparatus which houses a rotating disk-type data recording medium, said air filtration apparatus comprising, a filter member, a holder for removably receiving and retaining said filter member, said holder comprising an elasticly deformable member having opposed surfaces between which said filter member is nipped, and means for fixing said holder in said sealed casing adjacent said disk-type data recording medium,
said elastically deformable member has means defining a slit in which said filter member is inserted and furthermore including engaging portions projecting outwardly at an open end of said slit, said sealed casing being provided with engaging channel means within which said engaging portions are engaged so as to narrow said slit, whereby said filter member is held by being nipped by said elastically deformable member when the member is engaged with said engaging channel.

21. An air filtration apparatus for collecting dust in a sealed casing of a disk drive apparatus which houses a rotating disk-type data recording medium, said air filtration apparatus comprising, a substantially planar filter member, a holder for removably receiving and retaining said filter member, said holder comprising an elastically deformable member having opposed surfaces between which said filter member is nipped, said sealed casing having means for supporting said holder peripherally adjacent the outer edge of said disk-type medium so that the plane of said filter member extends substantially in a direction of the radius of said disk-type medium, and further extends with the plane of said filter member disposed substantially orthogonal to the plane of said disk-type medium.

22. An air filtration apparatus for collecting dust in a sealed casing of a disk drive apparatus which houses a rotating disk-type data recording medium, said air filtration apparatus comprising, a filter member, a holder for removably receiving and retaining said filter member, said holder comprising an elastically deformable member having opposed surfaces between which said filter member is nipped, and means for slidably receiving said holder member in said sealed casing adjacent said disk-type data recording medium and for maintaining said holder in a closed configuration so that said opposed surfaces nip said filter member therebetween.
