RELATED U.S. APPLICATION DATA 
     This application is a continuation-in-part of U.S. patent application Ser. No. 10/448,079 filed May 30, 2003. 
    
    
     TECHNICAL FIELD 
     This invention relates generally to a single touch “scan to store” system. In particular the system includes a portable, free-standing universal scanner driver device for a person to scan a document via a scanner directly to a storage media therein from a single interaction with any scanner available in-situ. 
     BACKGROUND OF THE INVENTION 
     Document scanners are widely used for both business and home purposes. The optical scanner market continues to explode. Optical scanners differ from one another in terms of scanning technology, resolution, bit depth, size and shape. There are hand-held scanners, sheet-fed scanners, flatbed scanners (like photocopy machines), and overhead scanners (like overhead projectors). 
     An optical scanner reads text or images printed on paper and translates the information into digital data to be stored in a file, displayed on a screen, and manipulated by programs. Most optical scanners do not distinguish text from images (represented as bit maps). Therefore, a computer is required to edit text. To translate the image into ASCII characters, an optical character recognition (OCR) software is required to be installed in the computer. Typically, an analog-to-digital converter in the scanner processes the analog signal to generate a digital representation of this image. Most optical scanners sold today come with OCR packages. Current scanners require a variety of user intervention to carry out the scanning process and effectively store the document on a storage device, such as a disk, CD, or network share. 
     For example, HP ScanJet II cx is compatible with Macintosh and IBM compatible PC&#39;s. For the Macintosh hardware, the scanner can be connected directly to an existing SCSI interface. The recommended requirements for the Macintosh include: 5-8 megabytes of RAM (the minimum is 4), 6 megabytes of available disk space for installation of software (DeskScan II and/or Adobe Photoshop), and operation system software version 7.0 or greater (minimum is 6.0.7). For the PC the scanner requires an adapter card to be installed in the system. The software that does the actual scanning is called DeskScan II (on both Macintosh and PC). The image processing software is Adobe Photoshop for the Macintosh; and Aldus PhotoStyler and Image Assistant for the PC. The DeskScan II software does the actual scanning and includes some adjustments. The following are a few of the adjustments that can be made: adjusting the selection area, changing exposure settings, choosing a new image type, sharpening the image, or scaling the image to the right size. To enhance the images beyond what DeskScan offers requires image processing software such as Adobe Photoshop for the Macintosh, or Aldus PhotoStyler and Image Assistant for the PC. 
     U.S. Pat. No. 6,166,830 shows an integrated scan-to-store apparatus having a single housing unit, a flatbed scanner, a CPU, a monitor/screen, commands for controlling or making adjustments on a control panel, and a storing means disposed within. It further shows an integrated scan-to-store apparatus that allows images to be scanned and stored on a removable data/storage device. While it eliminates the need for a separate computer, it also eliminates the compatibility with any existing scanners by building a completely new scanner to include a CPU, monitor, scanner, and memory storage device as a single unit. In addition it still requires instructions from the operator and certain computer navigation procedures in order to allow choices to include: scanning, manipulating/adjusting, and storage. In particular it requires a high-powered CPU along with an extensive RAM and cache memory system, as well as various ports to allow this device to interface with other apparatus. In other words it compromises existing scanner design in exchange for a “self-contained, integrated configuration” in a stand-alone apparatus including a single housing (having a top surface and an interior space defined beneath said top surface), a high-end CPU processor, some “imagined” miniature monitor, and some sort of abbreviated keyboard. 
     U.S. patent application Publication No. 2002/0051242 shows an integrated scan-to-store apparatus having a CPU, a removable storage medium, and a control system displaying digital images. It further shows stand-alone flatbed scanner controls for controlling the mode of operation, degree of resolution, and related parameters associated with generating, storing, and displaying digital data, which requires substantially more input from an operator than U.S. Pat. No. 6,166,830 to control functions, such as: mode of operation, color or black and white, high-low-medium resolution, LCD display use, erase control, image advance and data compression, in addition to other “operator controlled functions.” It also includes ports for peripherals, an internal hard drive, and software adapted to display images directly on a screen. This application shares the same problem as U.S. Pat. No. 6,166,830, and it additionally incorporates a special carriage adapted within the unit with a digital camera positioned on this carriage so as to either conventionally scan a document or take a digital picture of the document. The digital camera picture would also allow viewing on a conventional TV set, and an adapter to couple an auto document feeder. 
     U.S. Pat. No. 4,943,868 encompasses a compact, lightweight image data filing apparatus with an IC memory card as an image data storing medium, and is primarily designed to be coupled with a hand-held scanner rather than being universally compatible with most optical scanners. Image data on an object such as a name card is read by the hand scanner, and filed into the IC memory card. The read data is stored into the IC memory card, together with an ID entered via the keyboard for identifying the image data to be stored. The image data is specified by the ID entered and displayed by a liquid crystal display device. As such, it requires additionally a keyboard for entering ID&#39;s and a display for displaying the image data. 
     Currently there is a demand for a portable, free-standing universal scanner driving device for a unskilled operator to scan a document directly to a storage media therein from a single interaction with any scanner available in-situ. 
     SUMMARY OF THE INVENTION 
     It is a purpose of this invention to provide a self-contained, portable, and universally compatible scanner driving device for any existing, unmodified scanner to be “plugged” into. 
     It is another purpose of this invention to eliminate the need for program navigation, a separate computer, monitor and keyboard. 
     It is still another purpose of this invention to provide an easy-to-use, single touch “scan to store” system.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     With reference to the figures, like reference characters will be used to indicate like elements throughout the several embodiments and views thereof. 
     Although the one-touch scan-to-store device of the present invention may incorporate any of a push-button, touch pad, or touch screen,  FIG. 1  shows the scan-to-store device  100  according to the invention to be connected with an external optical scanner, having a single push-button  10 , a slot  20  for receiving a storage medium such as a floppy disk, a slow-speed, low capacity processor and algorithms for manipulating a scanned image and saving it to the storage medium, a female RS-232 connector  30 , a female DIN connector  40 , a power cable  50 , a LCD display  60  for displaying textual user information, and a housing case  70 . Although not shown in  FIG. 1 , ports such as a USB port also may be provided for an external LCD display, numeric or alpha-numeric keypad, storage media, etc. 
       FIG. 2  is a block diagram of the components inside the one-touch scan-to-store device  100 , including a slow speed, low-capacity processor  80 , a memory control  81 , a RAM  82 , a ROM  83 , a disk controller  84 , input/output ports  85  and buses  86  (the data bus, the address bus, and the control bus) on a board of 2 inches by 2.5 inches by 0.5 inches. Because the device  100  incorporates a much slower CPU chip than a computer and much reduced RAM, the size of the internal cooling fan is significantly reduced or eliminated altogether. The invention merely includes a very low capacity processor with sufficient power and memory to drive an existing stand-alone scanner. The speed of the processor and the size of the RAM are contingent on the scanner and its driving software. 
     Like other processors, the processor  80  includes a ALU (Arithmetic Logic Unit), internal registers, and CU (control unit) for sequencing the system. The processor has three buses, a bi-directional data bus, mono-directional address bus, and a control bus. The data bus carries data between various components of the system, typically from memory to the processor or input/output controller. The address bus carries an address generated by the processor, which will select one internal register within one of the chips attached to the system and specifies the source or destination of the data which will carry along the data bus. The control bus carries various synchronization signals. The processor needs some sort of clock to synchronize the precise timing references of the system. 
     The input/output ports  85  include an input parallel port for inputting data from an optical scanner and an output port for outputting data to a storage medium. A standard parallel cable consisting of 25-pins that transfer information one byte at a time is used with the parallel port, such as a unidirectional, 4-bit parallel port. Preferably, the output port is a USB port. USB ports are very fast and have two data speeds: 12 mbps for devices such as scanners, printers, monitors, and modems. 
     The memory controller  81  controls data reading from and data writing to the memory, including the RAM  82  and ROM  83 , while the disk controller  84  controls data reading from and data writing to a disk. 
     Power is supplied via a transformer which converts the 120 volt, 50 Hz, AC current into +5- and +12 volt DC current, and a +3.3 volt as well on some systems. Usually the digital electronic components and circuits in the system (motherboard, adapter cards, and disk drive logic boards) use the 3.3 volt or +5 volt power, and the motors (disk drive motor and any fans) use the +12 volt power. 
     To simplify the device and its functions, the device does not include any co-processor, sound cards, graphic cards, or E-IDE interfaces. 
     Instead of a floppy disk, the disk controller and slot may accommodate a Hard Disk, an Optical Disk, a tape, a CD, a Worm, an Erasable, a Zip Disk, a DVD, a flash Memory Card, a Super Disk, media card, or a combination of two or more of these storage media. Alternatively, any such storage medium may be controlled by an external driver, although an internal CD burner would allow for the greatest compatibility with drivers. 
     The ROM and RAM may be substituted by a Programmable Read-Only Memory (PROM), an Erasable Programmable Read-Only Memory (EPROM), a Magnetic Disk, a Magnetic Tape, a Magnetic Drum, or Magnetic Disk, which will increase the performance of the device at the price of size and cost. 
     The operating system can be one of: Proprietary Software, Windows 2000, Windows 2000 Professional, Windows 2000 Server, Windows Server 2003, Windows XP, Windows NT, Windows ME, Windows 98, Windows 95, Windows 3.11, Windows-Longhorn, MS-DOS, PC-DOS, MXS, Mac OS X. Classic Macintosh, OS/2, Linux, Unix, NetBSD, OpenBSD, GNU Hurd, Solaris, SunOS, HP-UX, OpenVMS, Tru64, IRIX, NeXT, Rhapsody, AIX, MVS, NetWare, BeOS, AmigaOS, SCO OpenServer, SCO UnixWare, Pyramid, and BSDi. The application programming interfaces (API&#39;s), such as TWAIN, are available for each device and the chosen operating system will determine how much custom programming is required for this software. 
     The device  100  is designed to complement any existing scanners or their future designs. The miniaturized, slow-speed, low-memory, “computer substitute”, is small, lightweight and very portable. It can be connected (by AC plug and ISB cable for example) to, e.g., a flat bed scanner, without requiring or causing any modification to the scanner itself. This device  100  is totally separate from the scanner and is simply a substitute for the much larger, more powerful, more expensive, and much more complicated to operate computer. This design, by contrast, is only programmed to support a scanner, thereby allowing operator input to become as simple as operating a copy machine. 
     When used with an operating system that supports USB, devices can be added and removed without powering down or reconfiguring the system. When a device is added or removed, the system automatically detects the change and then loads or unloads the appropriate driver. 
     The stand-alone scanner driving device  100  is easy to operate. Once it is connected with an optical scanner, the assembly works as easily as a simple copy machine, which does not require a computer, monitor, or keyboard. As such the operation does not require the user to be computer literate. Because the unit would require less processing capabilities compared to today&#39;s computer technology, obsolete computer components can be used to manufacture the device. 
     According to the flow chart in  FIG. 3 , the user first turns on the device  100  power (Step  1100 ) by pressing the button  10  until hearing the power-up chime. Once power is on the LCD display  60  displays “Connect Scanner then Press Button” prompting the user to connect the device  10  to a scanner. The user connects the device to a scanner (step  1200 ) followed by pressing button  10 . The device  100  detects the type of scanner (step  1300 ) and retrieves the scanner&#39;s driver for supporting its operation with a specific operating system (step  1400 ). The retrieving process may be conducted via three ways: 1. Importing the scanner driver software from a storage medium received by the slot  20  or from a computer (step  1500 ); 2. Reading from the ROM  83  a pre-stored scanner driver (step  1600 ); or 3. downloading the scanner driver software via a computer, a PDA, or a cell phone from the internet (step  1700 ). In one embodiment, the device  100  is ordered on-line by an end user with at least one specific scanner driver installed. In another embodiment, the device  100  is pre-stored with at least one popular scanner driver. In this embodiment, the input button  10  and the LCD are replaced by a one touch panel on which different scanner drivers are displayed for a user to choose. Accordingly, the device  100  automatically configures a connected scanner (“connect-and-scan”). A user can connect the device  100  with a scanner and scan documents with the scanner without worrying about setting hardware or data transmission configurations. 
     If the device  100  cannot initialize due to the unavailability of its driver, the LCD display displays “Initialization Failed”. 
     Optionally the LCD display  60  may display the brand name and model number of the scanner. The LCD display  60  then displays “Insert Disk” after the scanner driver is retrieved. The user inserts a disk or the like into the slot  20  in step  1800 . The LCD display then displays “Place Doc” to prompt the user to place a to-be-scanned-document in the scanner (step  1900 ). The LCD display displays “Push to Scan &amp; Store” to control the device  100  to scan the document and store the information into the disk (step  2000 ). 
     There is one default graphic file type in the device  100 . However, in another embodiment the device supports many different graphic file types, such as bmp, jpg, tif, gif, png, and others. In this embodiment a variety of file formats are shown on the touch panel in the Save As dialog for the user to choose depending on how or where the file, image, or picture will be used. For example, scanning images for use on the World Wide Web is different from scanning images for printing. 
       FIG. 4  shows second embodiment of the invention in which the universal scanner driving device  100  also includes an external alpha-numeric keypad  200  connected via one of the ports, and appropriate software that allows the user to store multiple multi-page scanned documents in separate folders with meaningful filenames and sequentially numbered pages. Thus, the user can enter a document name via the alpha-numeric keypad  200 , push a control key on the keypad to indicate that a new document is being scanned, and then push the push-button  10  on the device  100  whereupon the system will automatically scan the document and save it into a new folder with a new page number sequence. Alpha-numeric keypads generally are small devices, such as those commonly found in cellular telephones and PDA&#39;s, which as a stand-alone device can be connected to device  100  using, for example, a USB cable and port. 
     According to the flow chart in  FIG. 5 , the user of the second embodiment of the universal scanner driving device follows steps  1100  to  1800  in the same manner as the user of the first embodiment. The user then connects an alpha-numeric keypad to a port in device  100  (step  1810 ). After placing a new document on the scanner (step  2100 ) the user optionally may enter a document name using the alpha-numeric keypad (step  2200 ), touch a control key on the numeric keypad  200  to indicate that a new document is to be scanned (step  2300 ), and push the push-button  10  on device  100  (step  2000 ), whereupon the system automatically scans the document and saves it into a new folder with a new page number sequence. 
     Both the LCD display and the alpha-numeric keypad may require custom programming. This would depend on the implementation used by the hardware vendor.
