Abstract
Abstract A mechanism for automatically taking up film strip material on to a driven spool comprises a fixed guide to direct the film around the spool, and a pivotally-mounted guide for directing the film back on to itself so the leading end is entrained between the spool and a remote portion of the film. The mechanism is contained within a cassette having an inlet slot for directing the film through nip rollers to the fixed guide.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
79 words
A mechanism for automatically taking up strip material to be wound on a spool, comprising a take-up spool, a fixed rigid guide member arranged, in use, to guide said strip material to and around said spool, and a pivotally mounted guide member arranged, in use, to guide said strip material from said fixed guide member around said take-up spool such that the leading end of said strip is gripped between said spool and a remote portion of said strip.
Claim 2
Dependent Claim
79 words
A mechanism for automatically taking up strip material to be wound on a spool, comprising a take-up spool, a fixed rigid guide member arranged, in use, to guide said strip material to and around said spool, and a pivotally mounted guide member arranged, in use, to guide said strip material from said fixed guide member around said take-up spool such that the leading end of said strip is gripped between said spool and a remote portion of said strip.
Claim 3
Dependent Claim
22 words
A mechanism according to claim 1, wherein said pivotally mounted guide member is pivotable about one end of said fixed guide member.
Claim 4
Dependent Claim
26 words
A mechanism according to claim 1, further comprising a resilient guide member that is arranged, in use, to urge said strip material against said take-up spool.
Claim 5
Dependent Claim
21 words
A mechanism according to claim 3, wherein said resilient guide member is mounted at one end on said rigid guide member.
Claim 6
Dependent Claim
20 words
A mechanism according to claim 4, further comprising means for biasing said pivotably mounted guide member towards said take-up spool.
Claim 7
Dependent Claim
32 words

Claim 10
Dependent Claim
93 words
A mechanism for automatically taking up strip material to be wound on a spool, comprising a take-up spool, and guide means arranged, in use, to guide said strip material around said spool such that the leading end of said material is gripped between the spool and a remote portion of the strip, said guide means comprising a fixed rigid guide member and a movable guide member, each of said members being curved about said spool with said movable guide member being mounted for pivotal movement about one end of said fixed guide member.
Claim 11
Dependent Claim
93 words
A mechanism for automatically taking up strip material to be wound on a spool, comprising a take-up spool, and guide means arranged, in use, to guide said strip material around said spool such that the leading end of said material is gripped between the spool and a remote portion of the strip, said guide means comprising a fixed rigid guide member and a movable guide member, each of said members being curved about said spool with said movable guide member being mounted for pivotal movement about one end of said fixed guide member.
Claim 12
Dependent Claim
34 words
A mechanism according to claim 9, further comprising a resilient guide mounted on said fixed guide near another end thereof and is arranged, in use, to urge said strip material against said take-up spool.
Claim 13
Dependent Claim
90 words
A mechanism for automatically taking up strip material to be wound on a spool, comprising a take-up spool, a resilient guide member fixed at one end and arranged, in use, to guide and bias said strip material to and around said spool, and a pivotally mounted guide member arranged, in use, to guide said strip material from said resilient guide member around said take-up spool such that the leading end of the strip is guided around the spool and gripped between the spool and a remote portion of the strip.
