RELATED APPLICATIONS 
       [0001]    This application is a divisional of Ser. No. 11/950,482 which was filed on Dec. 5, 2007. 
     
    
     TECHNICAL FIELD 
       [0002]    The present disclosure relates to a document feeder flag assembly. 
       BACKGROUND 
       [0003]    Modern table top sorters implement a variety of different approaches to feeding documents out of a hopper and onto a track or document path. Typical systems for feeding and transporting documents require feeding systems to feed documents in order, one at a time, from a stack in a hopper. These systems often include a nudger component to nudge the documents from the hopper into the feeder. 
         [0004]    Many large document sorters require feeder flag assemblies, which are essentially mechanisms used to push against a stack of documents in a hopper, forcing the documents up against the feeder/roller/nudger arrangement. Typically, an operator fills a hopper by taking a stack of around 100 to 200 documents in one hand and manually moving a flag with the other free hand to provide space in the hopper to load the document. Filling hoppers in this manner is somewhat tedious, requiring two hands to complete. 
         [0005]    Also, due to size constraints of table top sorters, the ability to use designs from the larger document sorters, which allow for on the fly loading, is impractical and far too pricey. Another area of concern in these table top machines is assembly requirements. Larger document sorter designs usually require an assembly line worker to affix components both above and below the baseplate, which slows down assembly time. Furthermore, designs requiring combined top and bottom assembly also require some form of through hole or slot for the mechanism to operate. Through holes and slots can add to document handling problems, causing documents to skew or tear and machines to slow down or hang. Because these designs require access to the bottom of the baseplate for assembly, component replacement requires extra disassembly of the sorter. 
         [0006]    For these and other reasons, improvements are desirable. 
       SUMMARY 
       [0007]    In accordance with the present disclosure, the above and other problems are solved by the following: 
         [0008]    In a first aspect, a document feeder flag assembly is disclosed. The document feeder flag assembly includes a baseplate and a pivot post attached to the baseplate. Further, there is a flag arm having a first side and a second side, the first side of the flag arm is attached to the pivot post. There is also a feeder flag having a first side and a second side, the first side of the feeder flag being attached to a second side of the flag arm. The document feeder flag assembly also includes a resistance device attached between the feeder flag and the flag arm. 
         [0009]    In a second aspect, a document processing machine is disclosed. The disclosed document processing machine allows operators to load documents into a hopper with one hand while the machine is operational. The document processing machine includes means for allowing documents to be loaded into a hopper with one hand and means for pushing documents in a hopper against a feeder mechanism. 
         [0010]    In a third aspect, a method for loading a running document processing machine with one hand is disclosed. The method includes creating a wedge shape between a flag arm in a document feeder flag assembly and a loaded stack of documents in a hopper, then grasping an unloaded stack of documents with one hand. Next, the unloaded stack of documents is slid into the wedge shape between the feeder arm and the loaded stack of documents in the hopper, thereby displacing the feeder flag assembly, thereby loading the unloaded stack of documents into the machine. 
         [0011]    In a fourth aspect, a document feeder flag assembly is disclosed. The assembly includes a baseplate and a document surface connected to the baseplate. The assembly further includes at least one first member connected to the baseplate, wherein the first member remains in an orientation generally parallel to the document surface. The assembly also includes at least one second member connected to the first member, wherein the second member changes its orientation relative to the first member and surface, thereby creating a space between the surface and the second member.

     DETAILED DESCRIPTION 
       [0018]    Various embodiments of the present disclosure will be described in detail with reference to the drawings, wherein like reference numerals represent like parts and assemblies throughout the several views. Reference to various embodiments does not limit the scope of the invention, which is limited only by the scope of the claims attached hereto. Additionally, any examples set forth in this specification are not intended to be limiting and merely set forth some of the many possible embodiments for the claimed invention. 
         [0019]    In general, the present disclosure relates to an improved document feeder flag assembly to be used in a document sorter or other document processing machine. The improved document feeder flag allows for single handed loading of documents into a document hopper by using an innovative flag design. 
         [0020]    Referring now to  FIG. 1 , an automated document processing system  10  is shown in which aspects of the present disclosure can be implemented. The automated document processing system  10  provides an overview of the basic steps required to process documents, such as checks, in a high-volume system in which user supervision is minimized. In one embodiment, the automated document processing system  10  is a check processing system used to print and scan checks at a financial institution or document processing company. In still other embodiments, the automated document processing system  10  is a document sorter or other generalized document management system. 
         [0021]    The automated document processing system  10  includes a document feeder  12  interconnected with a document sorter  14  along a path of travel  16  of documents. The document feeder  12  is generally a document take-up mechanism provided with a large number of documents that are required to be processed. The document feeder  12  generally selects a document from a stack of documents for insertion into the path of travel  16  of the automated document processing system  10 . The document feeder  12  generally includes a feeder flag assembly arranged to guide documents into the automated document processing system  10 . Further details regarding a possible implementation of the document feeder  12  are described in conjunction with  FIGS. 2-6 , below. 
         [0022]    The document sorter  14  is an endpoint at which the documents have been processed, and can include one or more sorting mechanisms configured to arrange physical documents in a desired manner. The path of travel  16  may be defined by any of a number of document movement and/or guiding mechanisms, such as rollers, guides, or other systems able to grip and move documents from the document feeder  12  to the document sorter  14 . 
         [0023]    A control system  18  is interconnected to the document feeder  12  and the document sorter  14  to control flow of documents along the path of travel  16 . The control system  18  can be an application level program configured to control flow and processing of documents. The control system  18  can reside on a general purpose or specific purpose computing system capable of communicating with the document feeder  12  and document sorter  14 . 
         [0024]    The control system  18  directs a number of document processing tasks to be performed by the automated document processing system  10 , as designated and/or selected by user requirements. In the embodiment shown, the automated document processing system  10  includes a scanning system  20  and a printing system  22 , directed by the control system  18 . The scanning system  20  can scan one side of the documents passing along the path of travel  16 , to store text and/or images displayed on the documents. The printing system  22  prints desired characters and/or images onto documents passing by the printing system along the path of travel  16 . The printing system  22  can incorporate a print assembly which is configured to print from a stationary printing aperture onto moving documents passing by the printing system along the path of travel. In the example of a check processing system, the printing system  22  can print an endorsement onto the back of a check which is being processed at a financial institution operating the automated document processing system  10 . Other functionality may be incorporated into the automated document processing system  10 , and other documents may be processed as well, by financial institutions or other document processing entities. 
         [0025]    By passing documents through the automated document processing system  10 , a large volume of documents can be processed. In the embodiment shown, the documents can receive printing and be electronically captured, such that various records can be stored for each of a large number of documents. In the case of a financial institution processing checks or other documents, that institution can endorse a large number of checks, can capture check images and routing information, and can appropriately sort each document for distribution back to its issuing institution. 
         [0026]      FIG. 2  and  FIG. 3  show two perspective views of a specific example of an improved document feeder flag assembly  100  in accordance with the present disclosure. A feeder flag  101  touches a stack of documents in a hopper (not shown). A first flag arm, front flag arm  102 , is hingedly attached to the side of feeder flag  101  which extends into the document processing system to guide the document into a path of travel and a second flag arm, back flag arm  103  is hingedly attached to the side of feeder flag  101  which extends adjacent to a stack of documents within the hopper. Dowel pins  104  may be used to attach feeder flag  101  to front flag arm  102  and back flag arm  103 . The other ends of front flag arm  102  and back flag arm  103  are attached to posts  105 . Posts  105  are attached to the top surface of a baseplate  106 . A spring  107 , or other suitable apparatus, is used to create resistance forcing the feeder flag  101  against the stack of documents in the hopper. This resistance created by spring  107  is sufficient to keep the documents in the hopper properly against a document feeder/nudger assembly  108 . 
         [0027]      FIG. 4  shows a schematic top view demonstrating positions of various parts of feeder flag assembly  100  when a document hopper  201  is empty and feeder flag assembly  100  is in an empty position. It can be seen by  FIG. 3  that when document hopper  201  is empty, both front flag arm  102  and back flag arm  103  are forced by the tension of spring  107  to push feeder flag  101  against document feeder/nudger assembly  108 . When document hopper  201  is empty, both front flag arm  102  and back flag arm  103  are angled from posts  105  toward document feeder/nudger assembly  108 . The space between back flag arm  103  and the opposing side of the document hopper makes wedge shape  210 . 
         [0028]      FIG. 5  shows a schematic top view demonstrating positions of various parts of feeder flag assembly  100  of  FIG. 1  when document hopper  201  is full and feeder flag assembly  100  is in the full position. It can be seen by  FIG. 4  that when the document hopper  201  is full, both front flag arm  102  and back flag arm  103  lie in planes parallel to the documents in document hopper  201 . Further, in the full position of this specific example, back flag arm  103  and feeder flag  101  lie generally serially in relation to one another and both lie in a generally parallel position with front flag arm  102 . 
         [0029]    From the full position, documents are fed one by one into the document processing system. As the documents are fed, the resistance of feeder flag assembly  100  continues to press against the document stack as it gradually gets smaller. As the stack gets smaller, feeder flag  101  continues to press against the documents and is positioned in a direction generally parallel to the document stack, though both front flag arm  102  and back flag arm  103  are at angles relative to feeder flag  101  and the document stack. The difference in angles between the stack of documents and feeder flag  101 , and both front flag arm  102  and back flag arm  103 , continues to get larger as the document stack continues to diminish in size. Eventually, if document hopper  201  is not refilled with more documents, all the documents would be fed out of document hopper  201 , leaving it empty as shown in  FIG. 4 . 
         [0030]      FIG. 6  shows a method of loading a document feeder, implementing an improved document feeder flag assembly in accordance with this disclosure. This method begins at Start  601 . At Wedge Creation Step  602 , wedge shape  210  is created by the space between back flag arm  103  and the document stack as the document stack gets smaller in document hopper  201 . One having skill in the art would recognize that wedge shape  210  can be created by the space between back flag arm  103  and the opposing side of document hopper  201  if document hopper  201  is empty. Wedge shape  210  facilitates one handed loading of document hopper  201 . At Unloaded Document Step  603 , the operator takes a stack of unloaded documents in one hand. Next, at Wedge Slide Step  604 , the operator slides the unloaded documents into wedge shape  210  with one hand, thereby displacing feeder flag assembly  100  at Assembly Displacement Step  605 . This results in the operator placing the stack of unloaded documents on top of the already loaded documents in document hopper  201 , at Document Placement Step  606  thereby loading the documents and ending the method at End  607 . 
         [0031]    The document feeder flag assembly described herein can be located within a variety of types of document processing systems, beyond the one described above in  FIG. 1 . For example, various printing systems or document sorting systems may incorporate such a feeder flag assembly. 
         [0032]    The above specification, examples and data provide a complete description of the manufacture and use of the composition of the invention. Since many embodiments of the invention can be made without departing from the spirit and scope of the invention, the invention resides in the claims hereinafter appended.
