<P>PROBLEM TO BE SOLVED: To improve reading precision of a barcode whose reading has been failed, to shorten a time for reading, and to reduce the burden on an operator's operation. <P>SOLUTION: The information processor includes: a read part for reading a barcode to generate first optical data; an analysis part for analyzing the first optical data to determine whether or not the first optical data are normal data corresponding to prescribed barcode standard; a collation storage part for storing correction data comprising second optical data generated by one or more barcode read in the past and normal code information corresponding to the second optical data; and a data collation part which searches for correction data when it is determined that the generated first optical data are not normal data, reads the normal code information corresponding to the second optical data, and determines that the code information included in the read barcode is the read normal code information when the second optical data matching the first optical data are detected. <P>COPYRIGHT: (C)2012,JPO&INPIT |
