Abstract
Abstract A disk pack cartridge opening and partitioning apparatus is described, particularly as adapted for inclusion in disk drive apparatus wherein each cartridge comprises a spreadable jacket containing a pack of compactly stacked, hole-encoded flexible magnetic recording disks. In a preferred embodiment, the apparatus provides means for automatically spreading the jacket followed by partitioning of the stack between a selected pair of adjacent disks.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
172 words
An automatic opener apparatus for opening a jacket container containing a concentric pack of partitionable flexible recording disks: said jacket comprising a pair of opposed relatively flat and flexible panels joined along three sides with a pack-admitting opening along the fourth side, each panel containing aperture means adapted to accommodate disk partitioning means and jacket-opening thrust means; said apparatus comprising in combination: actuator means; and a pair of opposed thrust means mounted and adapted to be automatically reciprocated, opposingly, toward and away from one another, by said associated actuator means; each of said pair of thrust means comprising at least one rod, positioned and dimensioned to matingly pass through an associated one of said aperture means in a respective jacket panel in a location remote from said disk pack; said actuator means being arranged to thrust the rods into the opposed jacket panels, through a respective aperture means, sufficient to part the jacket panels enough to accommodate rotation, partition and transducing operations on the disks in the pack housed within the jacket.
Claim 2
Dependent Claim
172 words
An automatic opener apparatus for opening a jacket container containing a concentric pack of partitionable flexible recording disks: said jacket comprising a pair of opposed relatively flat and flexible panels joined along three sides with a pack-admitting opening along the fourth side, each panel containing aperture means adapted to accommodate disk partitioning means and jacket-opening thrust means; said apparatus comprising in combination: actuator means; and a pair of opposed thrust means mounted and adapted to be automatically reciprocated, opposingly, toward and away from one another, by said associated actuator means; each of said pair of thrust means comprising at least one rod, positioned and dimensioned to matingly pass through an associated one of said aperture means in a respective jacket panel in a location remote from said disk pack; said actuator means being arranged to thrust the rods into the opposed jacket panels, through a respective aperture means, sufficient to part the jacket panels enough to accommodate rotation, partition and transducing operations on the disks in the pack housed within the jacket.
Claim 3
Dependent Claim
93 words
The combination as recited in claim 1, wherein each jacket panel includes a pair of spreader-holes disposed on opposite sides of the mid-point of said jacket opening; the holes in one panel being disposed adjacent said opening-side of the jacket and so as not to register with the holes in the other panel; and wherein each thrust means comprises a pair of like rods, disposed on opposite sides of the mid-point of said jacket opening, so as to register with an associated pair of said holes in the adjacent one of said panels.
Claim 4
Dependent Claim
55 words
The combination as recited in claim 2, wherein one pair of said holes has a first diameter adapted to accommodate first spreader rods of a like diameter and the other pair of holes has a second different diameter adapted to accommodate second spreader rods of a like diameter, different from that of said first rods.
Claim 5
Dependent Claim
22 words
The combination as recited in claim 3, wherein common linkage means is arranged to allow said actuator means to activate all rods.
Claim 6
Dependent Claim
25 words
The combination as recited in claim 4, wherein a first pair of said rods is disposed to pin the opposite jacket-panel fixedly to the apparatus.
Claim 7
Dependent Claim
42 words
The combination as recited in claim 5, wherein said actuator means is arranged and controlled to first actuate said first pair of rods; then later activate the other pair of rods; thereby pinning one jacket panel, then deflecting the other panel away.
Claim 8
Dependent Claim
91 words
The combination as recited in claim 6, wherein said linkage means is arranged to be automatically operated by depressing means for affixing the pack within the given jacket onto a rotatable turntable; and is also adapted to automatically operate said opposing rod pairs stepwise, first thrusting one pair of rods in one direction to pin the opposing jacket panel against fixed base means; and then actuating the other, opposed pair of rods in the opposite direction, and so urge the other panel away from said pinned panel adjacent said jacket mouth.
