Abstract
Abstract A magazine is provided for supporting in alignment a plurality of magnetic disc packs each housing a magnetic disc. The magazine includes an insertion opening for loading a magnetic disc pack into the magazine and a withdrawal opening for withdrawing a magnetic disc pack from the magazine. The magazine includes a plurality of grooves formed on its bottom surface through which can be passed a withdrawal member for engagement with a magnetic disc pack for withdrawing the magnetic disc pack from the magazine. The withdrawal opening can be at least partially covered by an openable lid which includes a sensing surface matching with a direction regulating surface of the magnetic disc pack. The magazine can also include a retractable sensing member having a surface adapted to abut against a magnetic disc pack.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
154 words
A magazine for supporting in alignment a plurality of magnetic disc packs each housing a magnetic disc, said disc packs being adapted to be withdrawn from said magazine by a withdrawal member, said magazine comprising a housing portion formed by a plurality of partition plates arranged at regular intervals in said magazine, said magnetic disc packs being housable in alignment in said housing portion, an insertion opening for loading a magnetic disc pack into said magazine along a longitudinal insertion direction of said magazine, a withdrawal opening for withdrawing a magnetic disc pack, said withdrawal opening being formed in a rear end face of said magazine opposite to a forward end face having said insertion opening, and a plurality of grooves being formed on a bottom surface of said magazine through which can be passed a withdrawal member for engagement with a magnetic disc pack for withdrawing a magnetic disc pack from said magazine.
Claim 2
Dependent Claim
154 words
A magazine for supporting in alignment a plurality of magnetic disc packs each housing a magnetic disc, said disc packs being adapted to be withdrawn from said magazine by a withdrawal member, said magazine comprising a housing portion formed by a plurality of partition plates arranged at regular intervals in said magazine, said magnetic disc packs being housable in alignment in said housing portion, an insertion opening for loading a magnetic disc pack into said magazine along a longitudinal insertion direction of said magazine, a withdrawal opening for withdrawing a magnetic disc pack, said withdrawal opening being formed in a rear end face of said magazine opposite to a forward end face having said insertion opening, and a plurality of grooves being formed on a bottom surface of said magazine through which can be passed a withdrawal member for engagement with a magnetic disc pack for withdrawing a magnetic disc pack from said magazine.
Claim 3
Dependent Claim
46 words
A magazine as set forth in claim 1, wherein the withdrawal opening for drawing out said magnetic disc pack is at least partially covered with an openable lid, said openable lid including a sensing surface matching with a direction regulating surface of said magnetic disc pack.
Claim 4
Dependent Claim
59 words
A magazine as set forth in claim 2, wherein the housing portion of said magazine includes a retractable sensing member, biased by a resilient member into said housing portion, said sensing member having a surface adapted to abut against said magnetic disc pack, said surface being oriented in a direction perpendicularly intersecting the longitudinal insertion direction of said magazine.
Claim 5
Dependent Claim
50 words
A magazine as set forth in claim 3, wherein an end of said sensing member opposite said surface projects from said housing portion when said surface abuts said magnetic disc pack for detecting the presence of said magnetic disc pack when said magnetic disc pack is received in said magazine.
Claim 6
Dependent Claim
127 words
A magazine for supporting in alignment a plurality of magnetic disc packs each housing a magnetic disc, said disc packs being adapted to be withdrawn from said magazine by a withdrawal member, said magazine comprising a housing portion, having a height and a width, for housing a plurality of magnetic disc packs, an insertion opening for loading a plurality of magnetic disc packs into said housing portion of said magazine along a longitudinal insertion direction of said magazine, and a withdrawal opening for withdrawing said magnetic disc packs, said withdrawal opening being distinct from said insertion opening and extending for height and width of the housing sufficient to permit any disc pack within the housing to be selectively removed without the removal of any other disc packs.
Claim 7
Dependent Claim
127 words
A magazine for supporting in alignment a plurality of magnetic disc packs each housing a magnetic disc, said disc packs being adapted to be withdrawn from said magazine by a withdrawal member, said magazine comprising a housing portion, having a height and a width, for housing a plurality of magnetic disc packs, an insertion opening for loading a plurality of magnetic disc packs into said housing portion of said magazine along a longitudinal insertion direction of said magazine, and a withdrawal opening for withdrawing said magnetic disc packs, said withdrawal opening being distinct from said insertion opening and extending for height and width of the housing sufficient to permit any disc pack within the housing to be selectively removed without the removal of any other disc packs.
Claim 8
Dependent Claim
47 words
The magazine of claim 5, further comprising a plurality of grooves formed in a wall of said magazine through which can be passed a withdrawal member for engagement with a magnetic disc pack located within the housing portion for withdrawing a magnetic disc pack from said magazine.
