Abstract
Abstract A system records graphic data in microimage form on either a temporary, recording medium or a permanent microfiche. Full-size reproductions are made by projecting the recorded microimages onto a photosensitive medium. The reproductions are made via the temporary storage medium when a quick copy of the original data is desired; they are made from the microfiche when the full-size reproductions are to be retrieved from long-term storage. The system can also display the recorded graphic data.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
173 words
A system for recording data on microfiche and for viewing and making prints of the recorded data comprising A. a lens system with an axis, B. means for holding a microfiche and positioning it relative to the lens system axis, C. light transmitting platen for supporting a document, D. first light means arranged for illuminating a document on the platen, E. means for directing an image of the illuminated document in one direction along the lens system axis so that a latent micro-image of the document is imaged on the microfiche, F. means for reducing the latent micro-image to visible form, G. copying means, H. second light means positioned on the opposite side of the microfiche holding means from the lens system so that when the second light means is illuminated, said micro-image recorded on the microfiche in the holding and positioning means is projected in the opposite direction along the lens system axis, and I. means for directing the projected micro-image so that it is received and copied by the copying means.
Claim 2
Independent Claim
173 words
A system for recording data on microfiche and for viewing and making prints of the recorded data comprising A. a lens system with an axis, B. means for holding a microfiche and positioning it relative to the lens system axis, C. light transmitting platen for supporting a document, D. first light means arranged for illuminating a document on the platen, E. means for directing an image of the illuminated document in one direction along the lens system axis so that a latent micro-image of the document is imaged on the microfiche, F. means for reducing the latent micro-image to visible form, G. copying means, H. second light means positioned on the opposite side of the microfiche holding means from the lens system so that when the second light means is illuminated, said micro-image recorded on the microfiche in the holding and positioning means is projected in the opposite direction along the lens system axis, and I. means for directing the projected micro-image so that it is received and copied by the copying means.
Claim 3
Dependent Claim
53 words
A system for recording data on microfiche and for viewing and making prints of the recorded data as defined in claim 1 and further including A. a screen, and B. means for moving the means for directing the micro-image so that the projected visible micro-image on the microfiche is displayed on the screen.
Claim 4
Dependent Claim
66 words
A system for recording data on microfiche and for viewing and making prints of the recorded data as defined in claim 2 and further including a lens movable into a position so that its axis coincides with the lens system axis, said lens shortening the focal length between the lens system and the screen so that an image on the microfiche is projected onto the screen.
Claim 5
Dependent Claim
61 words
A system for recording data on microfiche and for viewing and making prints of the recorded data as defined in claim 1 A. wherein said microfiche is exposed by near ultraviolet light and the image thereon is fixed by heat, and B. means for selectively applying heat to the exposed portion of the microfiche so as to fix the micro-image thereon.
Claim 6
Dependent Claim
84 words
A system for recording data on microfiche and for viewing and making prints of the recorded data as defined in claim 1 wherein the holding and positioning means includes means for supporting a temporary storage medium, said positioning means being movable so as to place the temporary storage medium on the lens system axis so that the image of a document on the platen is recorded on the temporary storage medium, said image being removable from the system after it has served its purpose.
Claim 7
Dependent Claim
44 words
A system for recording data on microfiche and for viewing and making prints of the recorded data according to claim 5 wherein the temporary medium is a film which is A. exposed by near ultraviolet light, and B. erased by the application of heat.
Claim 8
Independent Claim
151 words
A system for recording data on microfiche and for viewing and making prints of the recorded data comprising A. a surface for supporting a document, B. means for illuminating the surface, C. a lens system, D. means for reflecting the image of the document on the surface in one direction along the lens axis, E. means for holding a light transmitting storage medium and positioning it on the lens axis on the opposite side of the lens from the reflecting means so that the image of the document is recorded on the storage medium, F. a seCond light positioned behind the storage medium and the positioning means, G. copying means, and H. means for moving the reflecting means so that when the second light illuminates the storage medium, the image of the data thereon is projected in the opposite direction along the lens axis to and copied by the copying means.
Claim 9
Independent Claim
151 words
A system for recording data on microfiche and for viewing and making prints of the recorded data comprising A. a surface for supporting a document, B. means for illuminating the surface, C. a lens system, D. means for reflecting the image of the document on the surface in one direction along the lens axis, E. means for holding a light transmitting storage medium and positioning it on the lens axis on the opposite side of the lens from the reflecting means so that the image of the document is recorded on the storage medium, F. a seCond light positioned behind the storage medium and the positioning means, G. copying means, and H. means for moving the reflecting means so that when the second light illuminates the storage medium, the image of the data thereon is projected in the opposite direction along the lens axis to and copied by the copying means.
Claim 10
Dependent Claim
62 words
A system for recording data on microfiche and for viewing and making prints of the recorded data as defined in claim 7 and further including A. a display screen, and B. means for moving the reflecting means so that when the second light illuminates the storage medium in the positioning means, the image of the data thereon is displayed on the screen.
Claim 11
Dependent Claim
66 words
A system for recording data on microfiche and for viewing and making prints of the recorded data as defined in claim 7 wherein said positioning means A. supports and positions a permanent storage medium and a temporary storage medium, and B. is adjustable so that either storage medium may be positioned on the lens axis to receive the image of a document on the transparent surface.
Claim 12
Dependent Claim
67 words
A system for recording data on microfiche and for viewing and making prints of the recorded data as defined in claim 9 wherein A. the permanent storage medium is a photographic microfiche which is exposed by near ultraviolet light and fixed by heat, and B. the temporary storage medium is a photochromic film which is exposed by near ultraviolet light and erased by the application of heat.
Claim 13
Dependent Claim
68 words
A system for recording data on microfiche and for viewing and making prints of the recorded data as defined in claim 10 and further including heating means movable into engagement with a portion of the storage medium on the lens axis so as to fix the image thereon if it is a permanent storage medium and to erase the image thereon if it is a temporary storage medium.
