`DIGITAL MICROFORM IMAGING
`APPARATUS
`
`CROSS-REFERENCE TO RELATED
`APPLICATIONS
`
`This application is a continuation of co-pending U.S.
`patent application Ser. No. 13/968,080 which was filed on
`Aug. 15, 2013, which was titled "Digital Microform Imaging
`Apparatus", which is a continuation of U.S. patent applica(cid:173)
`tion Ser. No. 13/560,283, now U.S. Pat. No. 8,537,279 which
`was filed on Jul. 27, 2012, which was titled "Digital Micro(cid:173)
`form Imaging Apparatus", which is a continuation of U.S.
`patent application Ser. No. 11/748,692, filed on May 15,
`2007, now U.S. Pat. No. 8,269,890, dated Sep. 18, 2012, and
`titled "Digital Microform Imaging Apparatus," each of which
`are incorporated herein by reference in their entirety.
`
`FIELD OF THE DISCLOSURE
`
`The present disclosure relates to a digital microform imag(cid:173)
`ing apparatus.
`
`BACKGROUND OF THE DISCLOSURE
`
`30
`
`Microform images are useful in archiving a variety of
`documents or records by photographically reducing and
`recording the document in a film format. Examples of typical
`microform image formats include microfilm/microfiche,
`aperture cards, jackets, 16 mm or 35 mm film roll film, car(cid:173)
`tridge film and other micro opaques. A microfiche article is a
`known form of graphic data presentation wherein a number of
`pages or images are photographically reproduced on a single
`"card" of microfiche film (such as a card of3x5 inches to 4x6
`inches, for example). Any suitable number of pages (up to a
`thousand or so) may be photographically formed in an
`orthogonal array on a single microfiche card of photographic
`film. The microfiche film may then be placed in an optical
`reader and moved over a rectilinear path until an image or a
`selected page is in an optical projection path leading to a
`display screen. Although other electronic, magnetic or optical
`imaging and storage techniques and media are available,
`there exists an extensive legacy of film type records storing
`the likes of newspapers and other print media, business
`records, government records, genealogical records, and the
`like.
`Past microfilm readers included an integral display which
`made the reader quite large, see for example U.S. Pat. No.
`5,647,654. As the number of images that can be put on a 50
`standard size varies, and also the size of the record, for
`example a typical newspaper page is larger than a typical
`magazine page, images are recorded on film within a range of
`reduction ratios (original size/reduced size), and aspect ratio
`(ratio ofheight to width of the image, or vice versa). A typical
`microfilm reader may have a range of zoom or magnification
`available to accommodate a portion of the reduction ratio
`range; however, this zoom range is limited and does not
`accommodate all reduction ratios. Further, in a microfilm
`reader of the type in the '654 patent, the optical system is
`enclosed and relatively fixed, and cannot be modified by a
`user to accommodate a range of reduction ratios for which it
`is not designed. With the adoption of new storage media such
`as CDs and DVDs, and the prevalent use of desktop comput-
`ers in libraries and other facilities which store records, it 65
`became apparent that a microfilm reader which acts as a
`peripheral device to a desktop computer and uses the com-

`SUMMARY OF THE DISCLOSURE
`
`The invention comprises, in one form thereof, a digital
`microform imaging apparatus which includes a chassis which

`puter's display for displaying the film's images has several
`advantages. Such a device is shown in U.S. Pat. No. 6,057,
`941, for example.
`One of the advantages is that a single workstation can
`accommodate a variety of media such as microfiche or other
`film, optical media such as CDs and DVDs, and other elec(cid:173)
`tronic and magnetic media. Another advantage is that a single
`display is used for displaying a variety of media images.
`These advantages have led to the development of microfilm
`readers which work in conjunction with a desktop computer;
`however, known peripheral device microfilm readers still
`have the problem of accommodating a relatively large range
`of reduction ratios for the film images. One known solution is
`to provide a peripheral device microfilm reader with multiple
`zoom lenses to cover the full range of magnification required
`15 by the relatively large range of reduction ratios. There are
`several disadvantages to this approach which include the
`lenses end up missing or misplaced, the microfilm reader
`becomes undesirably large, and/or special instructions are
`required to swap out lenses which makes the different zoom
`20 lenses difficult to use. An apparatus and/or method is needed
`which can accommodate a relatively large range of reduction
`ratios without the need for changing out parts of the apparatus
`such as the lenses, or without the need for very expensive
`zoom lenses.
`U.S. Pat. No. 6,301,398 discloses an apparatus for process-
`ing microfiche images where two carriages ride on common
`rails, driven by lead screws and small DC servomotors, where
`one carriage carries the CCD camera board, and the other
`carriage carries an objective lens mounted upon a vertically
`moving lens board. In operation, the system's digital control(cid:173)
`ler solves a simple lens equation based upon three variables:
`lens focal length, optical reduction ratio and pixel resolution
`at original document scale, or "dots per inch" (dpi). It then
`drives the Z-axis carriages to their calculated positions. The
`controller then commands a succession of image scans, each
`35 time displacing the lens carriage slightly. It analyzes the
`images and then returns the lens carriage to the position
`giving best focus. Although this system can accommodate a
`variable optical reduction ratio, it has several disadvantages
`or limitations. Disadvantages include that the lens carriage is
`40 iteratively focused which can cause eye strain if a person is
`viewing the image during the focusing process, and this pro(cid:173)
`cess takes time. Another disadvantage is that the leads screws
`include backlash when reversing direction, which can make
`the iteratively focusing process difficult and/or imprecise, and
`45 the '398 patent is absent disclosure which discusses how to
`rectify such a problem. Yet another disadvantage is that illu(cid:173)
`mination system, film holder, lens and camera are all in line
`which creates a bulky system. Yet further, the '398 patent is
`absent disclosure which indicates what range of reduction
`ratios it can accommodate.
`Other noted U.S. patents are U.S. Pat. Nos. 5,137,347;
`5,726,773; 3,836,251; and 5,061,955. However, these pat(cid:173)
`ents, along with the other cited patents, together or separately,
`fail to disclose or suggest a compact digital microform imag(cid:173)
`ing apparatus which can easily adapt to a broad range of
`55 reduction ratios, and also fail to disclose or suggest such a
`device while offering other modern features leveraging the
`potential versatility available in such a system used in con(cid:173)
`junction with a computer system.
`What is needed in the art is a compact and versatile digital
`60 microform imaging apparatus which can easily adapt to a
`broad range of reduction ratios and media types while pro(cid:173)
`viding good resolution of the images and ease of use.

`The invention comprises, in another form thereof, a digital

`ured to support a microform media after the diffuse window

`microform media approximately 90 degrees along a second
`optical axis. An imaging subsystem includes a lens connected
`to a first carriage which is linearly adjustable approximately
`parallel with the second optical axis, and an area sensor
`connected to a second carriage which is linearly adjustable 15
`approximately parallel with the second optical axis.
`The invention comprises, in yet another form thereof, a
`digital microform imaging apparatus which includes a chas-
`sis and an imaging subsystem connected to the chassis. The
`imaging subsystem has a first lead screw and a second lead 20
`screw approximately parallel with the first lead screw. Each
`lead screw is connected to the chassis. The imaging sub(cid:173)
`system includes at least one approximately L-shaped carriage
`with a first leg threadingly coupled to the first lead screw and
`slidingly coupled to the second lead screw.
`An advantage of an embodiment of the present invention is
`that it provides a compact microfilm viewer/scanner.
`Another advantage of an embodiment of the present inven(cid:173)
`tion is that it can accommodate a broad range of image reduc(cid:173)

`Yet another advantage of an embodiment of the present
`invention is that it can accommodate a broad range of micro(cid:173)
`form media types such as all film types and micro opaques.
`Yet other advantages of an embodiment of the present
`invention are that it uses an area sensor to sense the image 35
`being displayed thereby eliminating the need for scanning
`individual images with a line sensor, and resulting in high
`resolution scans in a relatively short amonnt of time, for
`example one second.
`Yet another advantage of an embodiment of the present 40
`invention is that it provides 360° image rotation.
`Yet another advantage of an embodiment of the present

`
`BRIEF DESCRIPTION OF THE DRAWINGS
`
`The above-mentioned and other features and advantages of
`this invention, and the marmer of attaining them, will become
`more apparent and the invention will be better understood by
`reference to the following description of embodiments of the
`invention taken in conjunction with the accompanying draw(cid:173)
`ings, wherein:
`FIG. 1 is a perspective view of an embodiment of a digital
`microform imaging system according to the present inven(cid:173)

`FIG. 3B is an exploded, fragmentary, perspective view of
`the digital microform imaging apparatus of FIG. 2, illustrat(cid:173)
`ing particularly the X-Y table mobility;
`FIG. 4 is a perspective view of the digital microform imag(cid:173)
`ing apparatus ofFIG. 2 with the cover removed and as viewed
`from generally rearward of the apparatus, and particularly
`
`Referring now to the drawings, and more particularly to
`FIG. 1, there is shown a digital microform imaging system 20
`which generally includes digital microform imaging appara(cid:173)
`tus (DMIA) 22 connected to a computer 24. Computer 24 can
`45 include one or more displays 26, and user input devices such
`as a keyboard 28 and mouse 30. DMIA 22 and computer 24
`can be placed on a worksurface 32 of a desk, or other work(cid:173)
`surfaces, for convenient access and ease of use. DMIA 22 can
`be electrically connected to computer 24 via cable 34, which
`50 may provide communication using a FireWire IEEE 1394
`standard, for example.
`Computer 24 can be connected to a printer (not shown) or
`connected/networked to other computers or peripheral
`devices (also not shown) to print, store or otherwise convey
`55 images produced by DMIA 22. Although cable 34 is
`described as an electrical type cable, alternatively DMIA 22
`and computer 24 can communicate via fiber optics, or wire(cid:173)
`lessly through infrared or radio frequencies, for example.
`Referring more particularly to FIGS. 2-9, DMIA 22
`60 includes an approximately monochromatic illumination
`source 36, such as a light emitting diode (LED) array or other
`monochromatic illumination source, transmitting an incident
`light 38 through a diffuse window 40 along a first optical axis
`42 of apparatus 22. Light emitting diode (LED) array 36 can
`65 be an approximately 13 x9 array of individual LEDs operating
`in the 495-505 nm wavelength region, although array 36 is not
`limited to such parameters. The relatively monochromatic

`
`5
`nature of source 36 helps reduce chromatic aberration in
`DMIA 22, thereby improving the optical resolution of the
`images produced. Diffuse window 40 can be a frosted glass
`which diffuses the light emanating from array 36, thereby
`creating a more uniform illumination source. DMIA 22 can
`include cover 43 to help protect the inner elements ofDMIA
`22.
`A microform media support 44 is configured to support a
`microform media 46 after diffuse window 40 and along first
`optical axis 42. In the embodiment shown support 44 is an
`X-Y table, that is, support 44 is movable in a plane which is
`approximately orthogonal to first optical axis 42. Referring
`particularly to FIGS. 3A and 3B, microform media support 44
`includes frame 48 which supports first window 50 on one side
`of microform media 46, and second window 52 on the other
`side of microform media 46. Second window 52 hinges
`upward at 54 when frame 48 is moved forward to the extent
`that lever 56 (connected to second window 52) contacts ramps
`58 (one ramp on either side), and similarly, hinges downward
`at 54 when frame 48 is moved rearward as lever 56 is released
`from contact with ramp 58. In this way the microform media
`46, shown as a microfiche film withanarrayofimages 60, can
`be placed and held securely between windows 50, 52 for
`viewing. Frame 48, along with windows 50, 52 and media 46,
`are slidingly supported on rods 62 by bearings (not shown) to
`allow a transverse movement 63 of frame 48, windows 50, 52
`and media 46. Rods 62 are connected to brackets 64, which
`brackets are slidingly supported by chassis 66 and bearings
`(not shown) to allow a longitudinal movement 68 offrame 48,
`windows 50, 52, media 46 and rods 62.
`Referring particularly to FIGS. 6-8, an approximately 45°
`fold mirror 70 reflects the incident light transmitted through
`microform media 46 approximately 90° along a second opti-
`cal axis 72. First optical axis 42 and second optical axis 72 can
`be thought of as segments of the single or main optical axis.
`Mirror 70 is connected by a three point mount 76 to mirror
`mount 78 by fasteners 80 and springs 82. Mirror mount 78 is
`connected to chassis 66 as shown. Fold mirror 70 advanta(cid:173)
`geously shortens the overall longitudinal length of the optical
`axis which allows DMIA 22 to be more compact.
`An imaging subsystem 84 includes a first lead screw 86 and
`a second lead screw 88 where each lead screw is approxi(cid:173)
`mately parallel with second optical axis 72. A lens 90 is
`connected to a first carriage 92 which is linearly adjustable by
`rotating first lead screw 86. Lens 90 includes stop 94 and
`f-stop adjustment 96 which can adjust the aperture of stop 94.
`Lens 90 can have a fixed focal length of 50 mm, for example.
`This focal length has the advantage of a relatively large depth
`of focus. A rough formula used to quickly calculate depth of
`focus is the product of the focal length times the f-stop 50
`divided by 1000, which yields a depth offocus of0.55 mm for
`a 50 mm focal length and fll f-stop adjustment. An area
`sensor 97 is connected to a second carriage 98 which carriage
`is linearly adjustable by rotating second lead screw 88. Area
`sensor 97 can be an area array CCD sensor with a two dimen- 55
`sional array of sensor elements or pixels, for example, with a
`3.5 f.tm2 pixel size, or other types of sensors and pixel sizes
`depending on resolution size requirements. The area array
`nature of sensor 97, when compared to a line sensor, elimi(cid:173)
`nates the need for scanning of the sensor when viewing two 60
`dimensional images. The overall novel optical layout of the
`present invention including the separately adjustable area
`sensor 97 and lens 90; 45° fold mirror 70; and film table 44
`location; algorithms for moving the lens and sensor to appro(cid:173)
`priate respective locations to achieve proper magnification 65
`and focus of the image; and the lens focal length and relatively
`large depth of focus, allows DMIA 22 to auto focus without
`
`6
`the need for iterative measurements and refocusing the of! ens
`90 during magnification changes to accommodate different
`reduction ratios of different film media. Further, the present
`invention can easily accommodate reduction ratios in the
`range of 7x to 54x, although the present invention is not
`limited to such a range.
`A first motor 100 is rotationally coupled to first lead screw
`86 by timing pulley 102, belt 104 with teeth, and timing
`pulley 106, and a second motor 108 is rotationally coupled to
`10 second lead screw 88 by timing pulley 110, belt 112 with
`teeth, and timing pulley 114. A controller 116 is electrically
`connected to first motor 100, second motor 108 and area
`sensor 97, where controller 116 is for receiving commands
`and other inputs from computer 24 or other input devices,
`15 controlling first motor 100
