Abstract
Abstract The invention relates to an arrangement for automatically loading a floppy disc into a floppy disc drive unit, using a positioning motor that locates a magnetic head on various tracks on the floppy disc. After the floppy disc has been partly inserted in the floppy disc drive unit, the floppy disc is grasped by a gripping element disposed on a slide. The positioning motor moves the slide at the same time as the magnetic head so that the floppy disc is drawn into the floppy disc drive unit. Then the slide is locked. To eject the floppy disc, the lock is released and, guided by the positioning motor, the slide, together with the floppy disc, is partially ejected from the floppy disc drive unit.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
119 words
A floppy disc drive unit including device for automatically loading a floppy disc, said device comprising: a gripping arrangement movably mounted in said drive unit for gripping and moving a floppy disc between a loading/unloading position and a transducing position; a magnetic head carrier with a magnetic head mounted thereon; a positioning motor operatively coupled to said magnetic head carrier for moving said carrier in first and second directions to position said magnetic head on various tracks on the disc, said directions being the directions of loading and unloading, respectively, of the floppy disc; and connecting means releasably coupling said head carrier to said gripping arrangement so that operation of said positioning motor causes movement of said gripping arrangement.
Claim 2
Dependent Claim
119 words
A floppy disc drive unit including device for automatically loading a floppy disc, said device comprising: a gripping arrangement movably mounted in said drive unit for gripping and moving a floppy disc between a loading/unloading position and a transducing position; a magnetic head carrier with a magnetic head mounted thereon; a positioning motor operatively coupled to said magnetic head carrier for moving said carrier in first and second directions to position said magnetic head on various tracks on the disc, said directions being the directions of loading and unloading, respectively, of the floppy disc; and connecting means releasably coupling said head carrier to said gripping arrangement so that operation of said positioning motor causes movement of said gripping arrangement.
Claim 3
Dependent Claim
33 words
The invention of claim 1, wherein: a magnetic head carrier connects said magnetic head to said motor, said connecting means includes releasable engagement means for coupling said gripping means to said head carrier.
Claim 4
Dependent Claim
40 words
The invention of claim 1, wherein said releasable engagement means comprises: a spring connected to said gripping means for urging said gripping arrangement against said head carrier; and latching means for releasably latching said gripping means and said head carrier.
Claim 5
Dependent Claim
46 words
The invention of claim 3, wherein said latching means comprises: means defining a slot in said gripping means; and a spring-biased lever carrying a bolt having a head, said lever mechanism operable to insert said bolt in said slot with said head carrying said gripping means.
Claim 6
Dependent Claim
33 words
The invention of claim 4, wherein said gripping means comprises: the slide mounted for movement in the loading direction and in the unloading direction; and gripping elements carried spaced apart on said slide.
Claim 7
Dependent Claim
23 words
The invention of claim 5, wherein: said gripping elements are spaced to grasp corner portions of a floppy disc and include spring members.
Claim 8
Dependent Claim
24 words
