A diskette picker for gripping a magnetic storage disk and retracting it from a disk storage housing and releasing the disk for loading onto a disk drive, the picker after the disk has been used, returning the disk to the disk storage housing, the picker comprising: a pair of flippers pivotally mounted on a picker assembly the flippers including a flipper nose for engaging each side of the edge of the disk, a flipper arm integrally attached and extending outwardly from the flipper nose and a flipper arm pin attached to the end of the flipper arm; a spring having a pair of spring arms, the spring arms engaging the flipper arm pins for biasing the flipper noses inwardly toward each other; and release means for engaging the flippers and pivoting the flipper noses away from each other and releasing the disk when loading the disk on a disk drive.
Claim 2
Dependent Claim
150 words
A diskette picker for gripping a magnetic storage disk and retracting it from a disk storage housing and releasing the disk for loading onto a disk drive, the picker after the disk has been used, returning the disk to the disk storage housing, the picker comprising: a pair of flippers pivotally mounted on a picker assembly the flippers including a flipper nose for engaging each side of the edge of the disk, a flipper arm integrally attached and extending outwardly from the flipper nose and a flipper arm pin attached to the end of the flipper arm; a spring having a pair of spring arms, the spring arms engaging the flipper arm pins for biasing the flipper noses inwardly toward each other; and release means for engaging the flippers and pivoting the flipper noses away from each other and releasing the disk when loading the disk on a disk drive.
Claim 3
Dependent Claim
67 words
The picker as described in claim 1 further including a spring biased rocker pivotally mounted on top of the picker assembly, the rocker having a stop disposed adjacent the flippers, the stop biased in a down position blocking the entrance of the disk between the pair of flippers to prevent the flippers from engaging the disk when the disk is being returned to the disk storage housing.
Claim 4
Dependent Claim
65 words
The picker as described in claim 1 wherein the release means is a stationary cam plate having a first cam surface and a second cam surface, the first and second cam surfaces engaging the flippers for overcoming the bias force of the spring arms and urging the flippers away from each other for releasing the disk prior to loading the disk on the disk drive.
Claim 5
Dependent Claim
76 words
The picker as described in claim 1 wherein the picker assembly includes a first picker assembly arm and a second picker assembly arm extending outwardly therefrom, one of the flippers pivotally mounted on the first assembly arm, the other flipper pivotally mounted on the second assembly arm, the first and second picker assembly arms parallel to each other with the edge of the disk received therebetween when the flipper noses engage the edge of the disk.
Claim 6
Dependent Claim
260 words
A diskette picker for gripping a magnetic data storage disk and retracting it from a disk storage housing and releasing the disk during loading onto a disk drive, the picker after the disk has been used returning the disk to the disk storage housing, the picker comprising: a picker assembly having a first picker assembly arm and a second picker assembly arm parallel to each other and extending outwardly from the picker assembly; a first flipper pivotally mounted on the first picker assembly arm and a second flipper pivotally mounted on the second picker assembly arm, the flippers having a flipper nose, a flipper arm integrally attached to the flipper nose and a flipper arm pin attached to the end of the flipper arm; a spring having a pair of spring arms, the spring attached to the picker assembly, the arms of the spring engaging the flipper arm pins for pivoting the flipper noses toward each other, the noses of the flippers disposed in a spaced relationship to each other and adapted for receiving an edge of the disk therebetween; and a stationary cam plate having a first cam surface and a second cam surface, the surfaces disposed in a spaced relationship to each other and adapted for receiving the edge of the disk therebetween the first cam surface and the second cam surface engaging the flipper arm pins for overcoming the bias force of the spring arms and rotating the flipper noses away from each other and releasing the disk during loading of the disk on the disk drive.
