`DIGITAL MICROFORM IMAGING
`APPARATUS
`
`This application is a continuation of U.S. patent applica(cid:173)
`tion Ser. No. 11/748,692 which was filed on May 15,2007
`now U.S. Pat. No. 8,269,890 and which was titled "Digital
`Microform Imaging Apparatus" which is incorporated herein
`by reference in its entirety.
`
`FIELD OF THE DISCLOSURE
`
`The present disclosure relates to a digital microform imag(cid:173)
`ing apparatus.
`
`BACKGROUND OF THE DISCLOSURE
`
`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
`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(cid:173)
`ers in libraries and other facilities which store records, it
`became apparent that a microfilm reader which acts as a
`peripheral device to a desktop computer and uses the com(cid:173)
`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. 65
`These advantages have led to the development of microfilm
`readers which work in conjunction with a desktop computer;
`
`2
`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
`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
`10 required to swap out lenses which makes the different zoom
`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
`15 zoom lenses.
`U.S. Pat. No. 6,301,398 discloses an apparatus for process(cid:173)
`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
`20 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
`25 drives the Z-axis carriages to their calculated positions. The
`controller then commands a succession of image scans, each
`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
`30 variable optical reduction ratio, it has several disadvantages
`or limitations. Disadvantages include that the lens carriage is
`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
`35 include backlash when reversing direction, which can make
`the iteratively focusing process difficult and/or imprecise, and
`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
`40 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. Pat. Nos. 5,137,347; 5,726,773; 3,836,
`251; and 5,061,955. However, these patents, along with the
`45 other cited patents, together or separately, fail to disclose or
`suggest a compact digital microform imaging apparatus
`which can easily adapt to a broad range of reduction ratios,
`and also fail to disclose or suggest such a device while offer(cid:173)
`ing other modem features leveraging the potential versatility
`50 available in such a system used in conjunction with a com(cid:173)
`puter system.
`What is needed in the art is a compact and versatile digital
`microform imaging apparatus which can easily adapt to a
`broad range of reduction ratios and media types while pro-
`55 viding good resolution of the images and ease of use.
`
`SUMMARY OF THE DISCLOSURE
`
`The invention comprises, in one form thereof, a digital
`60 microform imaging apparatus which includes a chassis which
`has a microform media support structure, and an area sensor
`rotatably connected to the chassis.
`The invention comprises, in another form thereof, a digital
`microform imaging apparatus which includes an approxi(cid:173)
`mately monochromatic illumination source transmitting an
`incident light through a diffuse window along a first optical
`axis of the apparatus. A microform media support is config-

`

`
`US 8,537,279 B2
`
`3
`ured to support a microform media after the diffuse window
`and along the first optical axis. An approximately 45 degree
`fold mirror reflects the incident light transmitted through the
`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
`approximately parallel with the second optical axis.
`The invention comprises, in yet another form thereof, a 10
`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
`screw approximately parallel with the first lead screw. Each
`lead screw is connected to the chassis. The imaging sub- 15
`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)
`tion ratios without the need to change zoom lenses.
`Yet another advantage of an embodiment of the present
`invention is that it can accommodate a broad range of micro- 25
`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
`being displayed thereby eliminating the need for scanning
`individual images with a line sensor, and resulting in high 30
`resolution scans in a relatively short amount of time, for
`example one second.
`Yet another advantage of an embodiment of the present
`invention is that it provides 360° image rotation.
`Yet another advantage of an embodiment of the present 35
`invention is that it has low energy usage.
`Yet other advantages of an embodiment of the present
`invention are that it has either auto focus or manual focus.

`DETAILED DESCRIPTION OF THE
`DISCLOSURE
`
`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 45
`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)
`tion;

`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
`illustrating the correlation between the rotational movement
`of the motors and lead screws, and the translational move(cid:173)
`ment of the carriages;
`FIG. 5 is a top view of the digital microform imaging
`apparatus of FIG. 4;
`FIG. 6 is a side view of the digital microform imaging
`apparatus of FIG. 4;
`
`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
`include one or more displays 26, and user input devices such
`as a keyboard 28 and mouse 30. DMIA 22 and computer 24
`40 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
`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
`images produced by DMIA 22. Although cable 34 is
`described as an electrical type cable, alternatively DMIA 22
`50 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
`includes an approximately monochromatic illumination
`source 36, such as a light emitting diode (LED) array or other
`55 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
`be an approximately 13 x9 array of individual LEDs operating
`in the 495-505 nm wavelength region, although array 36 is not
`60 limited to such parameters. The relatively monochromatic
`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
`65 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 15
`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 20
`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° 25
`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 30
`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 35
`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. 40
`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
`divided by 1000, which yields a depth offocus of0.55 mm for 45
`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 dim en(cid:173)
`sional array of sensor elements or pixels, for example, with a 50
`3.5 fill12 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 scarming of the sensor when viewing two
`dimensional images. The overall novel optical layout of the 55
`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
`and focus of the image; and the lens focal length and relatively 60
`large depth of focus, allows DMIA 22 to auto focus without
`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 65
`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
`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,
`controlling first motor 100 and second motor 108, and other
`10 elements of DMIA 22, and for outputting an image data of
`area sensor 97. Consequently, controller 116 can include one
`or more circuit boards which have a microprocessor, field
`programmable gate array, application specific integrated cir-
`cuit or other progrmable devices; motor controls; a
`receiver; a transmitter; connectors; wire interconnections
`including ribbon wire and wiring harnesses; a power supply;
`and other electrical components. Controller 116 also provides
`electrical energy and lighting controls for LED array 36. The
`lead screws serve a dual function of providing guiding ele(cid:173)
`ments as well as drive elements for lens and sensor carriages.
`It is contemplated that the present invention can include alter-
`nate designs which can separate these two functions of guid(cid:173)
`ing and driving using, for example, rails or unthreaded rods or
`a combination thereof for guiding, and a belt or rack and
`pinion arrangement or a combination thereof for driving.
`A third motor 118 is rotationally coupled to area sensor 97,
`where controller 116 additionally controls third motor 118
`through electrical connections as with motors 100 and 108.
`For example, controller 116 can rotate area sensor 97, using
`motor 118, timing pulley 120, belt 122 with teeth, and timing
`pulley 124, to match an aspect ratio of microform media 46,
`and particularly an aspect ratio of images 60. A light baffle
`126 can be connected to area sensor 97 to reduce stray light
`incident on sensor 97 and thereby further improve the reso(cid:173)
`lution and signal to noise ofDMIA 22. Light baffle 126 can
`have an antireflective coating at the front and inside surfaces
`of the baffle to further reduce stray light incident on sensor 97.
`Motors 100, 108 and 118 can be DC servomotors, or other
`motors.
`In order to autofocus DMIA 22 without iterations and
`successive measurements, and for other reasons, it is impor(cid:173)
`tant that backlash is minimized or eliminated when rotating
`lead screws 86, 88 to linearly actuate carriages 92, 98. Fur(cid:173)
`ther, lens 90 and area sensor 97 require a stable platform in
`order to maintain optical aligrnnent. Referring more particu(cid:173)
`larly to FIGS. 10 and 11 there is shown in detail lens carriage
`assembly 127 and area sensor carriage assembly 129, respec(cid:173)
`tively. First carriage 92 can beL-shaped with a first leg 128
`threadingly coupled to first lead screw 86 using a tubular
`fitting 130 coaxially mounted with first lead screw 86 and a
`toothed insert 132 inserted into slot 134 in tubular fitting 130
`threadingly engaging at least some of the threads of first lead
`screw 86. A biasing element in the form of 0-ring 136, for
`example, holds toothed insert 132 in slot 134 and biases
`toothed insert 132 against the threads of first lead screw 86.
`The threads of lead screws 86, 88 are approximately rectan-
`gular in profile, and teeth 138 of toothed insert 132 are trian(cid:173)
`gular. Further, lead screws 86, 88 can be made from stainless
`steel whereas toothed insert 132 can be made from a self
`lubricating polymer such as polyoxymethylene, sometimes
`referred by the brand name Delrin, or other Nylon-based
`products such as Nylatron, or other materials. When triangu(cid:173)
`lar teeth 138 are inserted into corresponding rectangular
`threads oflead screws 86, and biased thereto with 0-ring 136,
`one edge of each tooth is always engaging a corresponding
`edge of the rectangular thread, and the other edge of each
`tooth is always engaging the other corresponding edge of the

`as DMIA 22. Therefore, the microform media support struc(cid:173)
`ture according to the present invention is at least one of a X-Y
`table, a motorized roll film carrier, and a hand operated roll
`film carrier, and a cartridge film carrier.
`A preferred embodiment of the invention has been
`described in considerable detail. Many modifications and
`variations to the preferred embodiment described will be
`apparent to a person of ordinary skill in the art. Therefore, the
`invention should not be limited to the embodiments
`10 described. Rather, in order to ascertain the full scope of the
`invention, the claims which follow should be referenced.

`teeth 138 are immediately engaged with the threads regard(cid:173)
`less of clockwise or counterclockwise motion of the lead
`screws, and also regardless of their just previous clockwise or
`counterclockwise motion. First leg 128 is also slidingly
`coupled to second lead screw 88 with a bushing 140. A second
`leg 142 is connected to first leg 128, the second leg slidingly
`coupled to first lead screw 86 with another bushing 140. In a
`similar manner, second L-shaped carriage 98 includes a third
`leg 144 threadingly coupled to second lead screw 88 using
`another tubular fitting 130, toothed insert 132 and 0-ring 13,
`and slidingly coupled to first lead screw 86 using a bushing
`140. A fourth leg 146 is connected to third leg 144, where
`fourth leg 146 is slidingly coupled to second lead screw 88
`using another bushing 140.
`Lens carriage assembly 127 can include a three point
`adjustable mount for lens 90 by mounting lens 90 to first
`carriage 92 using plate 148, ring 150, fasteners 152 and
`springs 154.
`Computer 24 can include a software computer user inter- 20
`face (CUI) 156 displayed by display 26 with user inputs to
`control DMIA 22 in general, and particularly, illumination
`system 36, motors 100, 108 and 118, and other elements of
`DMIA 22. Referring to FIG. 12, CUI 156 can include the
`following software user input buttons: positive/negative film 25
`type 158; landscape/portrait film orientation 160; rotate opti(cid:173)
`cal162 for rotating third motor 118; optical zoom 164 which

`rotation 166; mirror image 168 for adjusting for when media
`46 is placed on support 44 upside down; brightness 170 which 30
`adjusts the speed of sensor 97; contrast 172; focus 174 with
`manual focus (-I+) and autofocus (AF), also controlling first
`motor 100; digital magnifier 176; live button 178; scan type/

`computer drive #3 190; save image scan to email192; print
`image 194; restore settings 196; save settings 198; setup/tools
`200; and motorized roll film controls 202 for embodiments 40
`with motorized roll film attachments. A programmer with
`ordinary skill in the art in Windows, or other, operating sys(cid:173)
`tems, and C++ or Visual Basic programming language can
`create the CUI 156 as shown in FIG. 12 and defined above.
`CUI 156 images the image data 204 from sensor 97 on display 45
`26.
`Illumination source 36 can alternatively include lasers or
`laser diodes, electroluminescent panels, light sources with
`narrow band light filters, or other monochromatic sources.
`Media 46 can include any microform image formats such as
`microfilm/microfiche, aperture cards, jackets, 16 mm or 35
`mm film roll film, cartridge film and other micro opaques.
`Micro opaques are different than transparent film. Images are
`recorded on an opaque medium. To view these micro images
`one needs to use reflected light. The present invention can use
`LED arrays 37 (FIGS. 6 and 7) for use with micro opaques,
`which can be the same, or similar to, the monochromatic
`LED's
