Abstract
Abstract A fixed disk storage unit is mounted in a protective outer case, and is supported at one end by a flexible cable which connects a connector of the protective outer case with the fixed disk storage unit in the protective outer case, and supported at the other end by using elastic shock absorbers against the elasticity of the flexible cable. A head/disk enclosure including a rotatable disk and a head actuator of the fixed disk storage unit therein, and an electronic card on which electronic circuits are mounted, are placed abreast on substantially the same plane in the protective outer case, and the head/disk enclosure is supported by the shock absorbers. This construction provides a shockproof and portable disk storage apparatus which is small-sized and whose manufacturing process is simple.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
114 words
A shockproof and portable disk storage apparatus, comprising: a fixed disk storage unit; an outer case housing the fixed disk storage unit therein; a connector provided at a first end of said outer case; a flexible cable provided in said outer case for electrically connecting said connector with said fixed disk storage unit, said flexible cable urging said fixed disk storage unit toward a second end of the outer case, opposite said first end, in said outer case; and a first shock absorber provided in said outer case at the second end of said case, for urging said fixed disk storage unit to the first end of said outer case against said flexible cable.
Claim 2
Dependent Claim
114 words
A shockproof and portable disk storage apparatus, comprising: a fixed disk storage unit; an outer case housing the fixed disk storage unit therein; a connector provided at a first end of said outer case; a flexible cable provided in said outer case for electrically connecting said connector with said fixed disk storage unit, said flexible cable urging said fixed disk storage unit toward a second end of the outer case, opposite said first end, in said outer case; and a first shock absorber provided in said outer case at the second end of said case, for urging said fixed disk storage unit to the first end of said outer case against said flexible cable.
Claim 3
Dependent Claim
33 words
The shockproof and portable disk storage apparatus according to claim 1, wherein said first shock absorber includes discrete elastic members provided on the inside wall at the second end of said outer case.
Claim 4
Dependent Claim
46 words
The shockproof and portable disk storage apparatus according to claim 2, wherein said elastic members are cylindrical, and one end thereof is fixed to the inside wall at the second end of said outer case and the other end thereof contacts said fixed disk storage unit.
Claim 5
Dependent Claim
60 words
The shockproof and portable disk storage apparatus according to claim 1, wherein second shock absorbers are provided on inner surfaces of one or more sides of said outer case, said sides being substantially orthogonal to said first and second ends, so as to support said fixed disk storage unit with being isolated from the inner surfaces of said outer case.
Claim 6
Dependent Claim
29 words
The shockproof and portable disk storage apparatus according to claim 4, wherein said second shock absorbers are discrete elastic members provided on the inner surfaces of said outer case.
Claim 7
Dependent Claim
42 words
The shockproof and portable disk storage apparatus according to claim 5, wherein said elastic members are cylindrical, and one end thereof is fixed to the inner surface of said outer case and the other end thereof contacts said fixed disk storage unit.
Claim 8
Dependent Claim
100 words
The shockproof and portable disk storage apparatus according to claim 1, wherein said fixed disk storage unit has a head/disk enclosure including a rotatable disk medium and a movable head actuator which is able to move over said disk medium for reading/writing therein and an electronic card which is fixed to the head/disk enclosure and on which electronic circuits for controlling the inside of said head/disk enclosure are mounted, and one end of said flexible cable is connected to said connector and the other end of said flexible cable is connected to card connector pins provided on said electronic card.
Claim 9
Dependent Claim
22 words
The shockproof and portable disk storage apparatus according to claim 1, wherein said outer case is made of materials which absorb shock.
