Abstract
A filing system is provided for locating a particular file contained in a file holder which contains a plurality of files. The apparatus includes a machine-readable code mounted on each of the files, a guide attached to each file holder, a scanner for reading the codes on the files in a file holder, and an indicator for indicating when the particular machine-readable code corresponding to the particular file is located. The apparatus uses an improved bar code in which character boundaries are eliminated and the number of ONE's and ZERO's in a code are variable, resulting in increased data density. The unique numeric values which result from the improved bar code sparsely populate the possible range of values, and therefore a mapping algorithm is provided to map the bar code values to a sequential numeric system for ease of use. The improved bar code system uses repeating basic patterns of bars separated by a MARK bar, and a basic pattern can be reconstructed if the scan view includes only one MARK bar surrounded by ONE and ZERO bars. The improved apparatus also utilizes an inventive perpendicular file tab which positions the bar code accurately for the scanner. Border bars are prov…
