Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
144 words
A slide attachment with a sound recording mechanism comprising: a casing including two halves, a reproducing opening and a driving opening provided on said casing, means for connecting said two halves of said casing, endless resilient strip record means disposed within said casing, for recording a sound on a helical grooved channel formed thereon, means for guiding said endless resilient strip record means, whereupon engagement of said guiding means with said resilient record means causes said resilient record means to deform and become tensioned so as to facilitate driving of said record means, means for supporting said guiding means and said endless resilient strip record means, pressure supporting means mounted on said casing, follower rolling means rotatably mounted near the driving opening of said casing, film slide supporting means provided on said casing, and, a film slide supported by said film slide supporting means.
Claim 2
Dependent Claim
144 words
A slide attachment with a sound recording mechanism comprising: a casing including two halves, a reproducing opening and a driving opening provided on said casing, means for connecting said two halves of said casing, endless resilient strip record means disposed within said casing, for recording a sound on a helical grooved channel formed thereon, means for guiding said endless resilient strip record means, whereupon engagement of said guiding means with said resilient record means causes said resilient record means to deform and become tensioned so as to facilitate driving of said record means, means for supporting said guiding means and said endless resilient strip record means, pressure supporting means mounted on said casing, follower rolling means rotatably mounted near the driving opening of said casing, film slide supporting means provided on said casing, and, a film slide supported by said film slide supporting means.
Claim 3
Dependent Claim
16 words
A slide attachment as set forth in claim 1, wherein said guiding means are guide rollers.
Claim 4
Dependent Claim
28 words
A slide attachment as set forth in claim 1, wherein said first-named supporting means are shafts supported on both inner surfaces of the two halves of said casing.
Claim 5
Dependent Claim
18 words
A slide attachment as set forth in claim 1, wherein said casing is formed of oPaque synthetic resin.
Claim 6
Dependent Claim
18 words
A slide attachment as set forth in claim 1, further comprising guide banks for guiding said strip record.
Claim 7
Dependent Claim
121 words
An audio-visual slide attachment comprising: a casing having at least first and second openings defined therein, said first opening providing access for a driving member and said second opening providing access for a sound pickup device, an endless resilient strip record disposed within said casing, for recording sound on a helical groove channel formed thereon, means for guiding said endless resilient strip record into alignment with said first and second openings defined in said casing, whereupon engagement of said guiding means with said resilient record means causes said resilient record means to deform and become tensioned so as to facilitate driving of said record means by said driving member, and means for supporting a single photographic film slide within said casing.
Claim 8
Dependent Claim
121 words
