PURPOSE:To convert a required specific area into binary value and to convert the binary value into a quaternary value by forming 4<n> square mesh divided areas in accordance with mesh dividing levels based upon hexadecimal numbers. CONSTITUTION:A specific area is equally divided into four parts respectively in the vertical and horizontal directions to form sixteen large-scale divided areas and hexadecimal numbers consisting of divided area specifying codes ''0''-''F'' are assigned to respective areas. Each large-scale divided area is equally divided into four parts respectively in the vertical and horizontal directions to form sixteen medium-scale divided areas and hexadecimal numbers consisting of the divided area specifying codes ''0''- ''F'' are assigned to respective areas. Each medium-scale divided area is equally divided into four parts respectively in the vertical and horizontal directions to form sixteen small-scale divided areas and hexadecimal numbers consisting of the divided area specifying codes ''0''-''F'' are assigned to respective areas. Binary bar codes corresponding to mesh dividing levels are formed on two vertical and horizontal sides on the outside of the outline of the formed part. Thus, the quaternary access code corresponding to the required specific area can be found out by converting the required specific area into a binary value on the basis of the bar code and then converting the binary value into a quaternary value. |
