Abstract
Abstract An integrated circuit package magazine and receptacle is provided in which one or both ends of a longitudinally elongated magazine tube (10) are cut-out to form inwardly facing spring gates (16) which have ends (18) abutting ends (22) of a series of integrated semiconductor packages (20) slidably contained on a rail surface (13) in the interior of the magazine. In its neutral inward position spring gate 16 functions to prevent egress of the semiconductor packages while allowing easy ingress of the packages by spring movement of the spring gate upwardly into a position in the same plane as the top wall (15) of the tube. The tube may take various exterior and interior configurations. Automatic release of semiconductor packages from the tube is provided by utilizing the tube in conjunction with a receptacle (30) having a longitudinal rail (34) onto which the magazine is insertable. The receptacle is of U-shaped cross-section and has an operating paw facing outwardly from the receptacle in a position to intersect and disable the spring gate (16) of the insertable magazine ( 10). A leaf spring (41) is provided to assist in guiding the magazine tube so that the paw engages and disables the magazine spring gate.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
155 words
A magazine for multiple semiconductor packages comprising an elongated tube having an interior cross-sectional configuration adapted to confine in sliding orientation particularly shaped semiconductor packages: means on at least one end of said tube for partially closing said end and preventing egress of packages confined in said tube, said means comprising a spring gate attached to said tube and extending inwardly from a wall surface of said tube to intersect in its normal neutral position a front end of a semiconductor package, said package facing said at least one tube end and slidable in said tube and wherein said spring gate is attached to said wall surface adjacent an end of said tube and extends angularly into said tube and in a direction away from said tube end, said spring gate being deflectable toward said tube wall surface out of intersection with said package front end to allow egress of a package from said tube.
Claim 2
Dependent Claim
155 words
A magazine for multiple semiconductor packages comprising an elongated tube having an interior cross-sectional configuration adapted to confine in sliding orientation particularly shaped semiconductor packages: means on at least one end of said tube for partially closing said end and preventing egress of packages confined in said tube, said means comprising a spring gate attached to said tube and extending inwardly from a wall surface of said tube to intersect in its normal neutral position a front end of a semiconductor package, said package facing said at least one tube end and slidable in said tube and wherein said spring gate is attached to said wall surface adjacent an end of said tube and extends angularly into said tube and in a direction away from said tube end, said spring gate being deflectable toward said tube wall surface out of intersection with said package front end to allow egress of a package from said tube.
Claim 3
Dependent Claim
29 words
The invention of claim 1 in which said spring gate has a cantilevered end extending toward said tube wall and adapted to abut the end of a confined package.
Claim 4
Dependent Claim
48 words
The invention of claim 2 in which said cantilevered end is curved upwardly to a position below said wall but sufficiently close to the wall so as to permit manual lifting of said spring gate to a deflected position so that it no longer abuts a confined package.
Claim 5
Dependent Claim
41 words
The invention of claim 1 in which said tube includes an interior longitudinal rail portion on which DIP packages are slidably contained end-to-end, said spring gate in its neutral position contacting said rail portion to prevent egress of said DIP packages.
Claim 6
Dependent Claim
30 words
The invention of claim 1 in which a spring gate is provided at each end of said tube, each of said gates extending longitudinal of said tube toward each other.
Claim 7
Dependent Claim
48 words
The invention of claim 1 further including means for deflecting said spring gate outwardly from its position within said tube to the plane of said wall of said tube so that said spring gate may be disabled, allowing free entry and exit of semiconductor packages into said tube.
Claim 8
Dependent Claim
24 words
The invention of claim 1 in which said spring gate is a discrete clip adapted to be clipped on an end of said tube.
Claim 9
Dependent Claim
151 words
In combination, a magazine for multiple semiconductor packages comprising an elongated tube having an interior cross-sectional configuration adapted to confine in sliding orientation particularly shaped semiconductor packages; means on at least one end of said tube for partially closing said end and preventing egress of packages confined in said tube, said means comprising a spring gate attached to said tube and extending inwardly from a wall surface of said tube to intersect in its normal neutral position an end of a semiconductor package slidable in said tube; and means cooperating with said magazine for automatically opening said spring gate, said cooperating means comprising a magazine receptacle having means for deflecting the spring gate of said magazine into a deflected position upon insertion of said magazine into said receptacle to allow opening of the end of said tube allowing egress of semiconductor package therefrom and entrance of said package to said receptacle.
Claim 10
Dependent Claim
151 words
In combination, a magazine for multiple semiconductor packages comprising an elongated tube having an interior cross-sectional configuration adapted to confine in sliding orientation particularly shaped semiconductor packages; means on at least one end of said tube for partially closing said end and preventing egress of packages confined in said tube, said means comprising a spring gate attached to said tube and extending inwardly from a wall surface of said tube to intersect in its normal neutral position an end of a semiconductor package slidable in said tube; and means cooperating with said magazine for automatically opening said spring gate, said cooperating means comprising a magazine receptacle having means for deflecting the spring gate of said magazine into a deflected position upon insertion of said magazine into said receptacle to allow opening of the end of said tube allowing egress of semiconductor package therefrom and entrance of said package to said receptacle.
Claim 11
Dependent Claim
52 words
The invention of claim 8 in which said receptacle include rail means for receiving said tube and wherein inward movement of said tube on said rail means forces said spring gate against said deflecting means and moves said spring gate out of intersecting position with the end of a confined semiconductor package.
Claim 12
Dependent Claim
36 words
The invention of claim 8 including leaf spring means extending from said receptacle above said deflecting means for guiding said magazine wall surface above said deflecting means and engaging said deflecting means with said spring gate.
Claim 13
Dependent Claim
19 words
The invention of claim 10 including means on said receptacle for adjusting the position of said leaf spring means.
Claim 14
Dependent Claim
38 words
The invention of claim 10 in which said receptacle has a U-shaped cross section and said leaf spring means is cut out from and integrally formed in a spring plate mounted across the legs of said U-shaped receptacle.
Claim 15
Dependent Claim
32 words
The invention of claim 8 in which said deflecting means is an operating paw connected to the receptacle extending toward the entrance of a receptacle channel in which the magazine is insertable.
Claim 16
Dependent Claim
31 words
The invention of claim 13 in which said receptacle has a U-shaped cross section and said paw is attached to a bridge member mounted across the legs of said U-shaped receptacle.
Claim 17
Dependent Claim
35 words
The invention of claim 14 in which said bridge member includes depending means for mounting said paw and positioned to positively stop an inserted end of said magazine preventing further inward movement into the receptacle.
Claim 18
Dependent Claim
51 words
The invention of claim 8 in which said tube has a flat upper wall extending longitudinally of the tube, said spring gate being integrally attached to said upper surface adjacent an end of said tube and extending angularly downward into said tube and in a direction away from said tube end.
Claim 19
Dependent Claim
31 words
The invention of claim 16 in which said spring gate has a cantilevered end extending upwardly toward said tube upper wall and adapted to abut the end of a confined package.
