One of bar codes is constituted as an index code in a different manner from the other bar codes constituted as numerical codes. These bar codes are scanned sequentially and converted into corresponding parallel digital signals. Code scanning directions are discriminated with reference to the parallel digital signal corresponding to the index code. A plurality of registers adapted to memorize each parallel digital signal are triggered in forward and reverse sequences, when the scanning directions are discriminated to be forward and reverse, respectively. | |
