Ultra-high reduction microfiche layout and positioning mechanism therefor

Claim 2

A selector component for use when locating image pages and materials presented in ordered arrangement on a layout sheet comprising a selector body, a carrier for said sheet mounted for movement with respect to said body, a vertical guide system for constraining vertically oriented movements of said sheet carrier, a horizontal guide system for constraining horizontally oriented movements of said sheet carrier, guide ways provided by said body, separate horizontal and vertical selector plates mounted on said guide ways for reciprocal movement at angles of 90° one to the other, means constraining said sheet carrier for movement with either of said horizontal or vertical selector plates, and indexing means for establishing relative horizontal and vertical positioning of said guide ways, guide systems and sheet carrier.

Claim 3

Structure as set forth in claim 1 wherein horizontal and vertical movements of said carrier can be made independently of movements of said vertical or horizontal selector plates, respectively.

Claim 4

Structure as set forth in claim 1 wherein a plurality of cam surfaces are provided on each of said selector plates.

Claim 5

Structure as set forth in claim 3 and further comprising index keys on said body for movement toward engagement with each of said selector plates.

Claim 6

Structure as set forth in claim 4 wherein cam elements are provided for each of said keys and cam surfaces are provided on each of said selector plates.

Claim 7

Structure as set forth in claim 5 wherein selection of any index key causes a corresponding engagement between the cam element of the key and the cam surface of said selector plate whereby the selector plate is moved to a position identified with the chosen index key.

Claim 8

Structure as set forth in claim 6 wherein said cam elements are pins attached to said keys and wherein said cam surfaces are cam slots provided in said selector plates.

Claim 9

Structure as set forth in claim 7 wherein all cam pins are positioned for engagement in only corelated cam slots.

Claim 10

Structure as set forth in claim 8 and further comprising additional means whereby a force tending to depress one index key results in the engagement of the associated cam pin in its proper cam slot thereby establishing the position of said selector plate and sheet carrier.

Claim 11

Structure as set forth in claim 7 wherein the layout sheet is a film strip of a standard size aperture card and further comprising a system for the organization of image pages disposed on said film strip whereby the pages of a book may be laid out in horizontal rows and vertical columns with said rows corresponding to the tens of a decimal system and the vertical columns corresponding to digits thereof and wherein said indexing means is useful for selecting a particular image page of said presentation.

Claim 12

Structure as set forth in claim 10 wherein the cam slots on each selector plate are disposed in spaced positions whereby selection of numerically adjacent index keys will cause movement of said selector plate a distance corresponding to the size of one image page on said film strip.

Claim 13

Structure as set forth in claim 10 and further comprising a lock system for said index keys whereby a depressed key will be held in engaged position.

Claim 14

Structure as set forth in claim 12 wherein said lock system is inclusive of a catch on each of said cam pins and a reciprocally movable locking plate for engagement with the catch of depressed keys.

Claim 15

A selector component for use with projectors to facilitate the selection for display of individual image pages and the detail materials thereof where the image pages are presented in ordered arrangement at a reduced size on a microfiche film strip comprising a support body, a magnifying lens mounted on said body, a high intensity light source supported by said body and projecting a beam of light therefrom, a film gate adjacent said lens and intercepting light from said light source for the reception of said film strip, a carrier deck for the support of said film strip mounted on said support body for movement independent of said film gate whereby separate image pages on the film strip may be moved into registration with the film gate, vertical and horizontal guide means for constraining vertically and horizontally oriented movements of said carrier, said image pages on said film strip being laid out in horizontal rows and vertical columns with said rows corresponding to the tens of a decimal system and the vertical columns corresponding to the digits thereof, and indexing means for establishing relative horizontal and vertical positioning of said guide means and carrier.

Claim 16

A selector component for use with projectors to facilitate the selection for display of individual image pages and the detail materials thereof where the image pages are presented in ordered arrangement at a reduced size on a microfiche film strip comprising a support body, a magnifying lens mounted on said body, a high intensity light source supported by said body and projecting a beam of light therefrom, a film gate adjacent said lens and intercepting light from said light source for the reception of said film strip, a carrier deck for the support of said film strip mounted on said support body for movement independent of said film gate whereby separate image pages on the film strip may be moved into registration with the film gate, vertical and horizontal guide means for constraining vertically and horizontally oriented movements of said carrier, said image pages on said film strip being laid out in horizontal rows and vertical columns with said rows corresponding to the tens of a decimal system and the vertical columns corresponding to the digits thereof, and indexing means for establishing relative horizontal and vertical positioning of said guide means and carrier.

Claim 17

Structure as set forth in claim 5 and further comprising index selectors identified with separate rows and columns for the selection of specific image pages.
