Abstract
Abstract A disk file device includes a stocker for accommodating a plurality of cartridges each holding a disk. A cartridge displacing mechanism with a cartridge rceiving container passes a cartridge through an opening formed in the casing. A carrier moves a cartridge between the cartridge displacing mechanism and the stocker and between the stocker and a disk. The opening formed in the casing is on the side of the stocker and the cartridge displacing mechanism has an electric motor for turning the cartridge receiving container through 180° when a cartridge is passed through the opening so that the carrier and the cartridge receiving container are prevented from colliding.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
151 words
A disk file device comprising: a stocker for accommodating a plurality of cartridges each holding a disk; a disk recording and reproducing device for writing data on said disk and reading data therefrom; a carrier for selectively supplying said cartridges from said stocker to said disk recording and reproducing device and for selectively supplying said cartridges from said disk recording and reproducing device to said stocker; a casing containing said stocker, said disk recording and reproducing device and said carrier with said carrier being located between said stocker and a first portion of said casing, said casing having a cartridge supplying and receiving opening which is formed in a portion of said casing other than said first portion; and a cartridge displacing mechanism including a cartridge receiving container for receiving a cartridge through said opening, and means for rotating said container so as to supply said received cartridge to said carrier.
Claim 2
Dependent Claim
151 words
A disk file device comprising: a stocker for accommodating a plurality of cartridges each holding a disk; a disk recording and reproducing device for writing data on said disk and reading data therefrom; a carrier for selectively supplying said cartridges from said stocker to said disk recording and reproducing device and for selectively supplying said cartridges from said disk recording and reproducing device to said stocker; a casing containing said stocker, said disk recording and reproducing device and said carrier with said carrier being located between said stocker and a first portion of said casing, said casing having a cartridge supplying and receiving opening which is formed in a portion of said casing other than said first portion; and a cartridge displacing mechanism including a cartridge receiving container for receiving a cartridge through said opening, and means for rotating said container so as to supply said received cartridge to said carrier.
Claim 3
Dependent Claim
44 words

Claim 4
Dependent Claim
46 words
A device as claimed in claim 1, in which said casing has a part which is recessed inwardly in such a manner as to be substantially U-shaped in vertical section, and said cartridge supplying and receiving opening is formed in said recessed part of said casing.
Claim 5
Dependent Claim
55 words
A device as claimed in claim 1, wherein said cartridge displacing mechanism further includes a surface identifying limit switch and said disk file device further comprises a controller including a microcomputer for identifying, in response to a detection signal output by said limit switch, the surfaces of said cartridge inserted into said cartridge displacing mechanism.
Claim 6
Dependent Claim
44 words
A device as claimed in claim 4, wherein said rotating means comprises a container driving electric motor spaced closer to an end of said cartridge receiving container which is not closest to said opening than to an end which is closest to said opening.
Claim 7
Dependent Claim
46 words
