Full Description:
BACKGROUND OF THE INVENTION  
         [0001]    1. Field of the Invention  
           [0002]    The invention generally relates to a single touch “scan to store” system. In particular, the system includes a portable, free-standing universal scanner driving 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.  
           [0003]    2. Description of the Related Art  
           [0004]    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 scanner, sheet-fed scanners, flatbed scanner (like photocopy machines), overhead scanners (like overhead projectors).  
           [0005]    An optical scanner reads text or images printed on paper and translate 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 electrical 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, a CD or network share.  
           [0006]    For example, HP ScanJet II cx is compatible with Macintosh and IBM compatible PCs. 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 (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; 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 the 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.  
           [0007]    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 adjustment 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 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 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.  
           [0008]    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, 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 patent 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.  
           [0009]    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 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 data entered, and displayed by a liquid crystal display device. As such, it requires additionally a keyboard for entering Ids, and a display for displaying the image data.  
           [0010]    Currently, there is a demand for a portable, free-standing universal scanner driving device for an 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  
         [0011]    It is a purpose of this invention to provide a self-contained, portable, and universal compatible scanner driving device for any existing, unmodified scanner to be “plugged” into.  
           [0012]    It is another purpose of this invention to eliminate the need for program navigation, a separate PC and a monitor.  
           [0013]    It is still another purpose of this invention to provide an easy-to-use, single touch “scan to store” system.

         [0015]    [0015]FIG. 1 shows a portable, free-standing universal scanner driving device according to the invention;  
         [0016]    [0016]FIG. 2 is a block diagram showing one embodiment of the hardware structure of the driving device shown in FIG. 1; and  
         [0017]    [0017]FIG. 3 is an operation flow chart of the driving device shown in FIG. 1. 
     
    
     DESCRIPTION OF THE PREFERRED EMBODIMENTS  
       [0018]    With reference to the figures, like reference characters will be used to indicate like elements throughout the several embodiments and views thereof.  
         [0019]    [0019]FIG. 1 shows the one-touch scan-to-store device  100  according to the invention to be connected with an external optical scanner, a single input button  10 , a slot  20  for receiving a storage medium, such as a floppy disk, a CPU 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 , and a LCD display  60  for displaying textual user information, and a housing case  70 .  
         [0020]    [0020]FIG. 2 is a block diagram of the components inside the one-touch scan-to-store device  100 , including a CPU  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 and control bus) on a board of 2″×2.5″×0.5″. Because the device  100  incorporates a much slower CPU chip than a computer and much reduced RAM, the size of internal cooling fan is significantly reduced or eliminated altogether. The invention merely includes a very low capacity unit of with sufficient power and memory to drive an existing stand-alone scanner. The speed of the CPU and the size of the RAM are contingent on the scanner and its driving software.  
         [0021]    Like other CPUs, the CPU  80  includes a ALU (Arithmetic Logic Unit), internal registers and a CU (control unit) for sequencing the system. The processor has three buses, a bi-directional data bus, mono-directional address bus and 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.  
         [0022]    The input/output ports  85  include an input parallel port for inputting data from an optical scanner, an output port for outputting date to an storage medium. A standard parallel cable consists of 25-pin that transfer information one byte at a time is used a the parallel port, such as an unidirectional, 4-bit parallel port. Preferably, the output port is a USB port. USB ports are very fast and has two data speeds. 12 Mbps for devices such as scanners, printers, monitors, and modems.  
         [0023]    The memory controller  81  controls data reading from and writing to the memory, including the RAM a 82  and ROM  83 , while the disk controller  84  controls data reading from and writing to the disk.  
         [0024]    The power supply via a transformer which converts the 120-volt, 50 Hz, AC current into +5- and +12 v DC current, and +3.3 v 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 v or +5 v power, and the motors (disk drive motors and any fans) use the +12 v power.  
         [0025]    To simplify the device and its function, the device does not include any co-processor, sound cards, graphic cards, or E-IDE interfaces.  
         [0026]    This software accepts input from the user and facilitates scanning and storage of the document.  
         [0027]    Instead of a floppy disk, the disk controller and slot may accommodate a Hard Disk, an Optical Disk, a tape, a CD, a Worm, a Erasable, a Zip disk, a DVD, a flash Memory Card, a Super Disk, or a combination of two or more of these storage media. Alternatively, any such storage medium may be controlled via an external driver.  
         [0028]    The ROM and the 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, a Magnetic Disc, which increase the performance of the device at the price of size and cost.  
         [0029]    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 Unix, IRIX, NeXT, Rhapsody, AIX, MVS, NetWare, BeOS, AmigaOS, SCO OpenServer, SCO UnixWare, Pyramid, BSDi.  
         [0030]    This device  100  is designed to complement any existing scanners or their future designs. The miniaturized, slow-speed, low-memory “PC 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 PC. This design, by contrast, is only programmed to support a scanner, thereby allowing operator input to become as simple as operating a copy machine.  
         [0031]    When used with an operating system that supports USB, devices can be added and removed without powering down or reconfiguring the computer. When a new device is added or removed, the system automatically detects the change and then loads or unloads the appropriate driver.  
         [0032]    The stand-alone scanner driving device  100  is easy to operate. Once It is connected with an optical scanner, the assembly works as easy as a simple copy machine, which does not require a computer monitor or a 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.  
         [0033]    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 the button  10 . The Device  10  detects the type of the scanner (step  1300 ) and retrieve 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 form a storage medium received by the slot  20  or a computer (step  1500 ); 2. Reading form the ROM  83  a pre-stored scanner driver (step  1600 ); 3. downloading the scanner driver software via a computer, a PDA, 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. 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 display  60  are replaced by 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.  
         [0034]    If the device  100  can not initialize the scanner due to the unavailability of its driver, the LCD display displays “Initialization fail”.  
         [0035]    Optionally, the LCD display  60  displays the brand name and the 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 ).  
         [0036]    There is one default graphic file type in the device  100 . However, in another embodiment, the device  100  supports many different graphic file types, such as, bmp, jpg, tif, gif png and others. 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.  
         [0037]    With the invention, a law office could use non-professional staff to scan documents onto output media without tying up the copy machine or computers. The documents could then be transferred to computers as needed. A local store that offers pay-per-copy service could have a scanner-driving device of the invention set next to the copier that would be pay-per-scan. Individuals could scan documents/pictures and put them on a floppy disk or e-mail them directly to someone.

         [0046]    Will transfer data to any number of storage medium i.e. if floppy disk is installed, it will store the information there—if no floppy disk is detected, it will automatically send data to ISB port (or other) for external hard drive, zip drive, CD burner or any other removable storage device or to a modem for internet access  
         [0047]    Professional offices will be able to give client, customer or patient an electronic copy of a report or document instead of (or in addition to) a traditional paper copy without having to rely on computer literate staff to prepare the copy  
         [0048]    Portability allows traveling professional to take scanner into the field: salesman, auditor, lawyer (for discovery) etc.  
         [0049]    Pay-per-use at Post Office, bank, retail store, mall, airport, library, college library etc. Encourages infrequent users (who don&#39;t even own a scanner) to copy, store or later transmit documents or pictures to friends or relatives, or to medical, financial, accounting and legal offices. (i.e., medical records to a new doctor, closing documents to a bank, tax documents to an accounting office or an updated contract draft to a law office.)
