Claim 14

The process of claim 10 and the added step of selecting different image reduction sizes at the time of microcopying so that all of said documents may be printed out at the same magnification ratio on the same size paper despite variations in the size of the original documents.

Claim 15

The process of claim 10, 11 or 12 wherein said web is electrosensitive film.

Claim 16

The process of claim 13 and developing said film by heating it.

Claim 17

The process of claim 13 and developing said film by applying a toner to said film after it is struck by the light of said document and then fixing said toner.

Claim 18

The process of claim 15 and the added step of automatically finding and printing every document which is identified on a single web by the same machine readable file symbol.

Claim 19

The process of claim 15 and the added step of advancing said web from document to document identified by the same machine readable file symbol responsive to manually applied advance control signals.

Claim 20

A microimage file system in a unitary machine having an image copy area, a microweb exposure and processing area, and an image display and printing area, said copy area comprising means for illuminating documents to be copied, means for transmitting images of said lit documents from said copy area to said exposure and processing area, means for adding manually selected machine readable file identification codes adjacent said transmitted image in said exposure and processing area, means for simultaneously recording said transmitted image and said codes on a charge-sensitized medium in said exposure and processing area, means for processing said image and codes, means responsive to a selection of a machine-readable code for retrieving at least one of those recorded images which are identified by said selected code, and means responsive to retrieval of said images for projecting said retrieved images from said exposure and processing area to said display and printing area.

Claim 21

A microimage file system in a unitary machine having an image copy area, a microweb exposure and processing area, and an image display and printing area, said copy area comprising means for illuminating documents to be copied, means for transmitting images of said lit documents from said copy area to said exposure and processing area, means for adding manually selected machine readable file identification codes adjacent said transmitted image in said exposure and processing area, means for simultaneously recording said transmitted image and said codes on a charge-sensitized medium in said exposure and processing area, means for processing said image and codes, means responsive to a selection of a machine-readable code for retrieving at least one of those recorded images which are identified by said selected code, and means responsive to retrieval of said images for projecting said retrieved images from said exposure and processing area to said display and printing area.

Claim 22

The unitary machine of claim 18 and rotatable mirror means for selectively diverting said transmitted images to or diverting said projected images from said exposure and processing area.

Claim 23

The unitary machine of claim 18 and light beam reflecting means interposed adjacent a path of said light transmission to transmit said images from a first source and said codes from a second source to said exposure and processing area.

Claim 24

The unitary machine of claim 18 and a multiposition flip mirror means in a path of said projected images, means responsive to said flip mirror means in one position for diverting said projected image onto a viewing screen and responsive to said flip mirror means in another position for divertng said projected image onto a printing medium.

Claim 25

The unitary machine of claim 18, 19, 20 or 21 wherein said medium is prepackaged for easy insertion or removal in said exposure and processing area whereby image storage capacity may be increased by switching prepackaged media.

Claim 26
