Loading/ejecting device for a magnetic disk cartridge

Claim 2

A loading/ejecting device for magnetic disk carriage comprising a housing frame, a cartridge holder for holding a cartridge inserted therein, a detector means for detecting a closed state of a magnetic head insertion aperture opening and closing shutter in the cartridge when it is inserted in the cartridge holder in a predetermined position, and a load stopping means for stopping the cartridge from assuming a loaded state upon detection of the closed state of said shutter by said detector means, said cartidge holder being provided with a pivotable lever one endof of which is capable of abutting said cartridge and serving as said detector means, and the other end of which is engageable with housing frame and is provided with an abutting portion for abutting a shutter operating portion of the cartidge to prevent the pivotal movement of said lever and thereby serving as said load stopping means.

Claim 3

The loading/ejecting device of claim 1 wherein said frame includes inverted-L shaped slots formed therein, said cartidge holder being guided along said slots and urged downwards in the front frame direction to assumed said loaded state.

Claim 4

A recording/reproducing device according to claim 1, wherein said lever is mounted on the upper surface of said cartridge holder.

Claim 5

A recording/reproducing device according to claim 1, wherein said other end of said lever is engageable with a notched portion formed in said frame.

Claim 6

A recording/reproducing device according to claim 1, having means for urging said one end of said lever in the direction of abutment with said cartidge.

Claim 7

A recording/reproducing device according to claim 1, wherein said shutter comprises a metallic plate and is connected to a shutter operating portion fitted in a groove formed in said cartridge, said shutter operating portion being urged resiliently in the direction of closing said magnetic head insertion aperture.

Claim 8

A loading/ejecting device for a magnetic disk cartridge comprising a housing frame, a cartridge holder for holding a cartridge inserted therein, a detector means for detecting a closed state of a magnetic head insertion aperture opening and closing shutter in the cartridge when it is inserted in the cartidge holder in a predetermined position, and a load stopping means for stopping the cartridge from assuming a loaded state upon detection of the closed state of said shutter by said detector means, said cartridge holder being provided with a pivotable lever one end of which is capable of abutting said cartridge and serving as said detector means, and the other end of which is engageable with the housing frame and is provided with an abutting portion for abutting a shutter operating portion of the cartidge to prevent the pivotal movement of said lever and thereby serving as said load stopping means, wherein said frame includes inverted-L shaped slots formed therein, said cartridge holder being guided along said slots and urged downwards in the front frame direction to assume said loaded state, and being moved by the operation of a push up member having an inclined portion.

Claim 9

A loading/ejecting device for a magnetic disk cartridge comprising a housing frame, a cartridge holder for holding a cartridge inserted therein, a detector means for detecting a closed state of a magnetic head insertion aperture opening and closing shutter in the cartridge when it is inserted in the cartidge holder in a predetermined position, and a load stopping means for stopping the cartridge from assuming a loaded state upon detection of the closed state of said shutter by said detector means, said cartridge holder being provided with a pivotable lever one end of which is capable of abutting said cartridge and serving as said detector means, and the other end of which is engageable with the housing frame and is provided with an abutting portion for abutting a shutter operating portion of the cartidge to prevent the pivotal movement of said lever and thereby serving as said load stopping means, wherein said frame includes inverted-L shaped slots formed therein, said cartridge holder being guided along said slots and urged downwards in the front frame direction to assume said loaded state, and being moved by the operation of a push up member having an inclined portion.
