Abstract
Abstract A process for microfilming and determination and storage of document film position information and evaluation of the data for reproduction of the document from the microfiche. The document specific identification or search data of a document to be filmed is fed into a computer memory, which outputs the memory address location opened in the form of a code to identify the document and reserves additional data storage space under the address. During filming of the document, the position data determined by a coordinate slide of the camera, controlled by a stepping motor on the microfiche, is reproducibly stored in the reserved memory location of the computer under the document specific data. The code associated with the document to be filmed is read by the camera or fed into it and passed to a camera memory. The filming data determined by the camera during filming of the document is correlated with the memory, which contains the identification and search data of the document under the address code. The procedure is carried out by a device for automatic microfilming of documents of different formats and for development of exposed microfiche in a continuous process with a computer controlled combination of certain systems.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
71 words
A microfilming method comprising the steps of: entering a document specific identification and search code into a computer; indexing a memory address corresponding to a document in accordance with said document specific identification code and reserving data storage space under said memory address; storing fiche image position data corresponding to a coordinate position of an image of a document on a fiche in said data storage space upon filming said document.
Claim 2
Dependent Claim
71 words
A microfilming method comprising the steps of: entering a document specific identification and search code into a computer; indexing a memory address corresponding to a document in accordance with said document specific identification code and reserving data storage space under said memory address; storing fiche image position data corresponding to a coordinate position of an image of a document on a fiche in said data storage space upon filming said document.
Claim 3
Dependent Claim
29 words
A method according to claim 1 further comprising the steps of: generating a machine-readable document specific identification code; and attaching said machine-readable document specific identification code to a document.
Claim 4
Dependent Claim
18 words
A method according to claim 2 wherein said machine-readable document specific identification code is a bar code label.
Claim 5
Dependent Claim
48 words
A method according to claim 2 wherein the step of entering further comprises the step of: machine reading said identification code from a document; and said step of storing further comprises the step of: generating said fiche image position from a stepped position of a document filming camera.
Claim 6
Dependent Claim
56 words
A method according to claim 4 further comprising the step of: entering said document specific identification code and said position data stored in said data storage space, on said fiche to actuate a coordinate slide, associated stepping motors, a retrieval device and a projector or camera so as to position a document image to be reproduced.
Claim 7
Independent Claim
192 words
An apparatus for microfilming documents comprising: means for automatic microfilming of variously formatted documents and contiguously developing exposed microfiche containing means for automatic introduction and transport of documents through an exposure station from a stack of documents of a certain format inserted, with a format adjusting device; a first interchangeable objective lens camera with an exposure and mirror system for the simultaneous imaging of document front and reverse sides coupled to an automatic film transport; a second camera with an exposure system for filming titles and continuous identifications in line with said interchangeable objective lens camera; an automatic film developing device; and a central position guidance and control system for positioning a plurality of document images on said microfiche with an input keyboard, a monitor and processor; means for associating a document specific identification code to a document located in a document transport path; means for reading said document specific identification code connected to said central position guidance and control system; first memory means for storing film and position information in a reserved storage location wherein an address of said storage location is indexed in accordance with said document specific identification code.
Claim 8
Independent Claim
192 words
An apparatus for microfilming documents comprising: means for automatic microfilming of variously formatted documents and contiguously developing exposed microfiche containing means for automatic introduction and transport of documents through an exposure station from a stack of documents of a certain format inserted, with a format adjusting device; a first interchangeable objective lens camera with an exposure and mirror system for the simultaneous imaging of document front and reverse sides coupled to an automatic film transport; a second camera with an exposure system for filming titles and continuous identifications in line with said interchangeable objective lens camera; an automatic film developing device; and a central position guidance and control system for positioning a plurality of document images on said microfiche with an input keyboard, a monitor and processor; means for associating a document specific identification code to a document located in a document transport path; means for reading said document specific identification code connected to said central position guidance and control system; first memory means for storing film and position information in a reserved storage location wherein an address of said storage location is indexed in accordance with said document specific identification code.
Claim 9
Dependent Claim
27 words
An apparatus according to claim 6 wherein said means for associating comprises: means for attaching a machine-readable label containing said document specific identification code to a document.
Claim 10
Dependent Claim
26 words
An apparatus according to claim 7 wherein said means for associating comprises a bar code printer and said document specific identification code is a bar code.
Claim 11
Dependent Claim
46 words
An apparatus according to claim 6 wherein said central position guidance and control system comprises: stepping motors for positioning said document image and outputting position values reflecting a document image position; and a second memory connected to said means for reading and said first memory means.
Claim 12
Dependent Claim
27 words
An apparatus according to claim 6 further comprising: a microfiche utilization device exhibiting a coordinate slide for positioning a document image connected to said first memory means.
Claim 13
Dependent Claim
49 words
An apparatus according to claim 6 wherein said means for automatic microfilming further comprises: an objective for filming a shuttered monitor image associated with said second camera; and wherein said automatic film transport exhibits a range extending to a title and identification imaging position associated with said second camera.
