Abstract
Abstract The core of a tape carrier is constructed separately from the flanges. Each flange is secured to the core by resilient fastening means which extend from the flange into an inner aperture of the core, to secure the flange to the core for rotation therewith. Advantageously the resilient fastening means comprise latches disposed and spaced peripherally of the central aperture of the core, recesses being formed in the core and extending radially of the aperture for engagement by the latches.

Claim 2
Dependent Claim
100 words
Tape carrier, comprising a hollow core having a substantially cylindrical outer surface for winding a tape thereon, and an inner wall portion generally coaxial with said outer surface; at least one flange member having a section extending radially outwardly from said outer surface, and a mounting portion received in said hollow core; abutment means on one of said portions; and latching means on the other of said portions and adapted to engage said abutment means with a snap action upon insertion of said mounting portion into said hollow core and operative for connecting said flange member to said hollow core.
Claim 3
Dependent Claim
36 words
Tape carrier as defined in claim 1, further comprising an additional flange member similar to said flange member; and wherein said mounting portions of said flange members extend into said hollow core from opposite sides thereof.
Claim 4
Dependent Claim
68 words
Tape carrier as defined in claim 2, wherein said latching means of each of said flange members comprises a plurality of resilient latches integral with the respective flange member, said latches being spaced peripherally of said mounting portion; and wherein said abutment means includes a plurality of recesses in said inner wall portion spaced peripherally of said hollow core and adapted to be engaged by the respective latches.
Claim 5
Dependent Claim
37 words
Tape carrier as defined in claim 3, wherein said recesses of said core to be engaged by said latches of one of said flanges are disposed also to be engaged by said latches of the other flange.
Claim 6
Dependent Claim
34 words
Tape carrier as defined in claim 3, wherein each of said resilient latches has a detent nose at a free end thereof, said nose extending radially outwardly therefrom to engage one of said recesses.
Claim 7
Dependent Claim
25 words
Tape carrier as defined in claim 5, wherein each of said detent noses has a bevelled surface to facilitate introducing the latch into the aperture.
Claim 8
Dependent Claim
39 words
Tape carrier as defined in claim 1, also including a collar on such flange member, said collar extending from the flange member in an axial direction opposite to said mounting portion to provide a bearing for the tape carrier.
Claim 9
Dependent Claim
32 words
Tape carrier as defined in claim 7, also including arm on at least one such flange member, said arm being disposed to be engaged by drive means for driving the tape carrier.
Claim 10
Dependent Claim
20 words
Tape carrier as defined in claim 1, also including means for centering said flange member with respect to said core.
Claim 11
Dependent Claim
17 words
Tape carrier as defined in claim 9, wherein said centering means are disposed between said latching means.
Claim 12
Dependent Claim
54 words
Tape carrier as defined in claim 1, wherein said core has at least one groove, extending outwardly from and axially along said inner, wall portion of said core; said tape carrier also having rib means extending from said flange member into said groove to secure said flange member to said core for rotation therewith.
Claim 13
Dependent Claim
89 words
Tape carrier as defined in claim 1, wherein said core comprises a first portion having an outer, arcuate, cylindrical surface extending peripherally over a major part of said core; a second portion extending radially outwardly from said cylindrical surface over a relatively small distance; and a clip the thickness of which approximately equals said distance and which extends peripherally over at least a substantial part of said cylindrical surface; said latching means extending from said flange member into portions of said portion peripherally corresponding to said arcuatE, cylindrical surface.
Claim 14
Dependent Claim
15 words
Tape carrier as defined in claim 1, wherein said core consists of synthetic plastic material.
Claim 15
Dependent Claim
16 words

Claim 16
Dependent Claim
57 words
Tape carrier as defined in claim 12, wherein said core has a groove extending outwardly from and axially along said core into said second core portion; said flange member having a pair of ribs extending into said groove and engaging said core laterally of said groove for securing said flange member to said core for rotation therewith.
Claim 17
Dependent Claim
124 words
Tape carrier, comprising a core having a first portion having an outer, arcuate cylindrical surface extending peripherally over a major part of said core, a second portion extending radially outwardly from said cylindrical surface over a relatively small distance, and a clip the thickness of which approximately equals said distance and which extends peripherally over at least a substantial part of said cylindrical surface, said core also having an inner aperture generally coaxial to said cylindrical surface; flange means extending radially outwardly from said cylindrical surface of said core; and resilient fastening means extending from said flange means at least into portions of said aperture which peripherally corresponds to said arcuate, cylindrical surface to secure said flange means to said core for rotation therewith.
Claim 18
Dependent Claim
124 words
Tape carrier, comprising a core having a first portion having an outer, arcuate cylindrical surface extending peripherally over a major part of said core, a second portion extending radially outwardly from said cylindrical surface over a relatively small distance, and a clip the thickness of which approximately equals said distance and which extends peripherally over at least a substantial part of said cylindrical surface, said core also having an inner aperture generally coaxial to said cylindrical surface; flange means extending radially outwardly from said cylindrical surface of said core; and resilient fastening means extending from said flange means at least into portions of said aperture which peripherally corresponds to said arcuate, cylindrical surface to secure said flange means to said core for rotation therewith.
