Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
145 words
An audio-visual apparatus comprising, in combination, magnetic sound reproducing means having a record support adapted to support an audio-visual record sheet, having a magnetic recording on one surface and graphic material on its other surface, with its magnetic recording surface facing downwardly while on said record support; a head including an illuminating light source, a projector lens and a reflector, said reflector directing, toward a screen, light rays reflected from said other surface of said sheet and passing through said projection lens; means supporting said head above said record support; and support means pivotally mounted on said magnetic sound reproducing means for supporting a Fresnel lens for pivotal movement toward said record support, said Fresnel lens having its irregular surface directed toward said audio-visual record sheet on said record support, said support maens clamping said audio-visual sheet in a predetermined position on said record support.
Claim 2
Dependent Claim
145 words
An audio-visual apparatus comprising, in combination, magnetic sound reproducing means having a record support adapted to support an audio-visual record sheet, having a magnetic recording on one surface and graphic material on its other surface, with its magnetic recording surface facing downwardly while on said record support; a head including an illuminating light source, a projector lens and a reflector, said reflector directing, toward a screen, light rays reflected from said other surface of said sheet and passing through said projection lens; means supporting said head above said record support; and support means pivotally mounted on said magnetic sound reproducing means for supporting a Fresnel lens for pivotal movement toward said record support, said Fresnel lens having its irregular surface directed toward said audio-visual record sheet on said record support, said support maens clamping said audio-visual sheet in a predetermined position on said record support.
Claim 3
Dependent Claim
34 words
An audio-visual apparatus, as claimed in claim 1, including positioning means on said record support cooperable with mating positioning means in said audio-visual sheet to correctly position said sheet on said sound reproducing means.
Claim 4
Dependent Claim
30 words
An audio-visual apparatus, as claimed in claim 2, in which said positioning means on said record support comprises upwardly projecting pins engageable in correspondingly located apertures in said audio-visual sheet.
Claim 5
Dependent Claim
47 words
An audio-visual apparatus, as claimed in claim 3, in which said audio-visual sheet comprises a base formed with at least two apertures for receiving said pins, a reflector surface on one surface of said base, and a magnetic recording surface on the opposite surface of said base.
Claim 6
Dependent Claim
16 words
An audio-visual apparatus, as claimed in claim 4, including a transparent layer on said reflector surface.
Claim 7
Dependent Claim
86 words
An audio-visual apparatus, as claimed in claim 1, in which said lens support means includes a frame plate mounting said Fresnel lens with its irregular surface facing downwardly; means pivotally connecting one edge of said frame plate to a location on said sound reproducing means spaced sufficiently from said record support so as not to interfere with mounting of said audio-visual sheet on said record support; and a transparent plate secured to said frame plate in protecting relation to the irregular surface of said Fresnel lens.
