Document inspection method for auto feeding device

Abstract

The invention is a method to inspect multiple conditions of an auto feeding device feeding standard inspection papers into a scanning device while the said auto feeding device in QC process. The method is to use a bar code printed on the standard inspection paper to recognize the conditions that feeding multiple papers in one time, paper jam, paper inclined, etc. The bar code is continuous and unique, and therefore, the results for which standard inspection paper happened problem and how many more papers needing to be inspected are known immediately.

What is claimed is:  
     
         1 . A document inspection method for auto feeding device, which can be used by a scanning device to scan a standard inspection paper fed by an auto feeding device for inspecting the said auto feeding device; wherein, there are at least two identical patterns on the standard inspection paper, and the two patterns are distributed symmetrically on the top of the standard inspection paper; the two patterns are the first priority to be scanned for inspection: 
 step 1: having the auto feeding device on a working position of the scanning device, and starting the auto-feeding device;    step 2: a state of auto feeding is starting, which means the auto feeding device feeds the standard inspection paper with patterns to a working position of scanning device;    step 3: the scanning device scans the standard inspection paper;    step 4: a reading unit in the scanning device reads the patterns on the standard inspection paper, and a recording device records the conditions while the patterns are scanned by scanning device;    step 5: the inspection for the single standard inspection paper is finished, if there are still some standard inspection papers in auto feeding device, then going back to step 2, otherwise, going to next step;    step 6: the whole process is done.    
     
     
         2 . The document inspection method for auto feeding device according to  claim 1 , wherein, the pattern is continuous.  
     
     
         3 . The document inspection method for auto feeding device according to  claim 1 , wherein, the pattern is unique.  
     
     
         4 . The document inspection method for auto feeding device according to  claim 1 , wherein, the pattern is type of bar code.  
     
     
         5 . The document inspection method for auto feeding device according to  claim 4 , wherein, the bar code is serial number.  
     
     
         6 . The document inspection method for auto feeding device according to  claim 1 , wherein, the reading unit in the scanning device reads the patterns on the standard inspection paper to happen any of the following conditions: 
 (1) multiple standard inspection papers are fed into scanning device in one time;    (2) standard inspection paper is jammed somewhere between the scanning device and the auto feeding device;    (3) standard inspection paper is inclined when laying out on scanning device.
