CROSS-REFERENCES TO RELATED APPLICATIONS 
       [0001]    This application claims the benefit and priority from U.S. Provisional Application No. 61/050,217, filed May 03, 2008, and entitled, “Library Patron Card Reader, EZ Tag System, &amp; CircT Software Library Management,” all of which is incorporated herein in its entirety by reference. 
     
    
     FIELD OF THE INVENTION 
       [0002]    The present invention relates generally to library checkout systems, and more particularly to systems for checking out library materials and management of the materials. 
       BACKGROUND OF THE INVENTION 
       [0003]    Modern libraries have experienced increased demands from patrons, in terms of needs for larger and larger holdings of books and other tangible materials. Accordingly, it is not uncommon for public libraries, for example, to handle collection and distribution of hundreds of thousands, or even millions, of books and materials. Tasks of librarians in handling these ever increasing volumes are often overwhelming. Librarian tasks involve both receiving materials returned from patrons (“check-in”) and distributing materials to patrons (“check-out”). These tasks, when manually performed by library personnel upon such ever-growing volumes of materials, greatly affects time required to perform the tasks. 
         [0004]    Further there have been many advances in cataloging software commonly where information is sent to the library&#39;s Integrated Library System (ILS) via the well established Standard Interface Protocol (SIP), both of which will not be described herein. Such systems may incorporate both bar code and/or RFID information associated with both patrons and library circulation materials. 
         [0005]    In attempts to respond to needs for automation of check-in and check-out tasks, several techniques, devices, and systems have been proposed. For example, U.S. Pat. No. 5,288,980 issued to Patel, et al., entitled “Library Check Out/Check In System” incorporated herein by reference thereto shows such a system. Thereshown is a “self check out/check in terminal for facilitating independent withdrawal or return of articles having article identifying indicia on opposing surfaces thereof, and alterable security indicia for indicating the circulation status of the article.” 
         [0006]    The aforesaid patent employs the common bar code, a computer coding system that uses a printed pattern of lines or bars to identify products, mail and packages, customer accounts, and the like. Bar codes are commonly read by optically scanning the printed pattern and using a computer program to decode the pattern. In a linear bar code system, the code itself contains no information about the item to which it is assigned but represents a string of identifying numbers or letters. When the code is read by an optical scanner linked to a computer, the computer can provide and record information about the item, such as, the item, size, and the like from and to databases. 
         [0007]    More particularly, bar code and/or RFID information, more specifically digital information unique to both patrons and library circulation materials, may be routed back and forth from a circulation desk in communication with the aforesaid selected ILS cataloging systems in accordance with a selected SIP protocol, for subsequent display on the check-out station display and/or printed receipt information. It should be noted that both the SIP and ILS are well known and therefore will not be described herein. 
         [0008]    Commonly, library patrons have a patron card that includes a bar code as exemplified by the aforementioned patent. Reading of the patron card barcode is generally accomplished by very complex, expensive scanning system that generally requires proper card insertion and orientation, and is less than 100% reliable. 
         [0009]    Therefore, there exists a need for a reliable patron card reader and library material bar code reader. 
       SUMMARY OF THE INVENTION 
       [0010]    It is an object of the present invention to provide a reliable barcode reader for a library patron card. 
         [0011]    In accordance with the present invention the bar code associated with the library patron card is imaged by a camera for subsequent conversion to a bar code sequence for subsequent data processing. 
     
    
     
       BRIEF DESCRIPTION OF THE DRAWINGS 
         [0012]      FIG. 1  is a plan view of a patron check-out circulation desk. 
           [0013]      FIG. 2  is an exemplary schematic diagram of the components employed in the bar code reader/processor of the present invention. 
       
    
    
     DETAILED DESCRIPTION OF THE INVENTION 
       [0014]    Referring to  FIG. 1 , thereshown is patron check-out work station  100  including a patron display or monitor  110  for display of current “Express Check Out” information as is well known, and the patron card reader/printer face plate  7  in accordance with present invention. 
         [0015]    Face plate  7  includes an aperture  130  having a glass window  135  affixed to, e.g., the back side  7   b  thereof by, for example, a selected silicone sealant. Also, face plate  7  includes a second aperture or slot  140  configured in both width and length to pass a chosen receipt paper therethrough. 
         [0016]    Details of an exemplary mechanism below faceplate  7  are particularly shown in  FIG. 2 . Face plate  7  is slidably coupled to housing  3  by way of a pair of compression gas springs  5  such that face plate  7  may be raised relative to the work station upon release of key actuated slam action locks  10 . One end of each of the springs  5  is fastened to the backside of plate  7 , and the other fastened to the frame assembly generally numerically designated by numeral  50 , the details of which are well within the art of the mechanical artisan and will only be briefly described herein. In one embodiment, however, frame assembly  50  may be telescopically mounted as illustrated to housing  3  by an arrangement of sliding members for easy access to components mounted thereto. 
         [0017]    Mounted to frame assembly  50  is a printer  16 , for example, a thermal printer, including associated power supply  4 . Fastened to the backside  7   b  of faceplate  7  is printer paper lip guide  9  for receiving paper from printer  16  all of which are aligned with printer slot  140 . A printer data cable  17 , for example a USB cable and associated connectors is operably connected to the library ILS for receiving information therefrom to be printed. 
         [0018]    Also mounted to frame assembly  50  is a barcode imager  24 , for example a CCD (CMOS charge coupled device) imager, similar to present day digital cameras and the like. An example of such an imager is one that has a USB output with a 5.1′ image distance characteristic. As illustrated, imager  24  is coupled to the frame assembly  50  through bracket assemble  23 ,  25 , and  28 . 
         [0019]    In the standby mode, the entire assembly is contained within housing  3  mounted to workstation  100  with the faceplate  7  secured in position on the work station  100 , and the imager  24  being configured and arranged to receive images of barcodes on patron cards or library materials for subsequent processing by image processing (not shown) for deriving the bar code information from the bar code on the patron card or library material at the glass window  135  facing imager  24 . 
         [0020]    In accordance with the present invention, a method has been described for reading a patron card with associated bar code by way of imaging the bar code as opposed to common complex bar code scanning techniques, thereby avoiding error an increasing reliably by image processing, not herein described. 
         [0021]    It should be appreciated that by producing an image of the bar code associated with the patron card or library material eliminates the need for complex scanning, and eliminates the need for bar code orientation requirements, by virtue of only computer processing of an image to determine the bar code for subsequent processing by the ILS. 
         [0022]    In turn, the printer may provide the desired receipt after recognition of the patron via the patron card bar code, and the library materials identified by their unique bar code. 
         [0023]    It is to be appreciated the exemplary mechanical schematic, particularly frame assembly  50 , may be arranged, modified, or added to, or other modifications, all of which are intended to be within the true spirit and scope of the present invention 
         [0024]    It should be appreciated that components of the invention aforedescribed may be substituted for other suitable components for achieving desired results, or that various accessories may be added thereto. 
         [0025]    Accordingly, these and other various changes or modifications in form and detail from the present invention as described may also be made therein, again without departing from the true spirit and scope of the invention as defined by the appended claims.
