Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
162 words
A mounting apparatus for aperture cards comprising cutting means for severing individual filmed images from a strip of film, said cutting means including a knife unit and a counter-knife unit, said knife unit being part of a plunger means having an edge facing the filmed image, and said plunger means serving to first sever and then to press the severed filmed image upon a mounting card, resilient counter-pressure frame means mounted opposite said plunger means, projection means including a light source, a condenser lens and an objective lens, forming an optical path, an opening in said plunger means positioned in said path, said condenser lens having a flat surface and being mounted in a portion of the plunger means facing the filmed image, the edge of the plunger means facing the filmed image being flush with said flat surface of said condenser lens, whereby said flat surface and said edge of said plunger together form a pressing means for the filmed image.
Claim 2
Dependent Claim
162 words
A mounting apparatus for aperture cards comprising cutting means for severing individual filmed images from a strip of film, said cutting means including a knife unit and a counter-knife unit, said knife unit being part of a plunger means having an edge facing the filmed image, and said plunger means serving to first sever and then to press the severed filmed image upon a mounting card, resilient counter-pressure frame means mounted opposite said plunger means, projection means including a light source, a condenser lens and an objective lens, forming an optical path, an opening in said plunger means positioned in said path, said condenser lens having a flat surface and being mounted in a portion of the plunger means facing the filmed image, the edge of the plunger means facing the filmed image being flush with said flat surface of said condenser lens, whereby said flat surface and said edge of said plunger together form a pressing means for the filmed image.
Claim 3
Dependent Claim
64 words
An apparatus according to claim 1 including a front plate having resilient pressing means directed toward said plunger means, said resilient pressing means having a pressing face, which pressing face is smaller than an opening of said mounting card, whereby said pressing face extends through the opening of said mounting card and presses the filmed image against said plunger means during the mounting process.
Claim 4
Dependent Claim
30 words
An apparatus according to claim 2 in which said pressing means are transparent, inwardly curved strips of film which bear against a filmed image under tension resulting from said curvature.
