Information reproducing system for optically reading a dot code from a recording medium

摘要

An information reproducing system for optically reading a dot code from a recording medium is provided wherein the dot code comprises a plurality of blocks arranged adjacent to one another. Each of the blocks has a block address pattern, a data dot pattern and a marker which are arranged at predetermined positions. The block address pattern is constituted of a plurality of optically readable dots and representing an address of the block in the dot code. The data dot pattern comprises a plurality of optically readable dots arranged in accordance with contents of information to be recorded. The marker is made of a pattern distinctly different from the data dot pattern, and is for recognizing an existence of the block and setting a reference position used for detecting the dots in the data dot pattern and the block address pattern in the block. Those markers between adjacent blocks are shared by said adjacent blocks. The information reproducing system comprises reading means for optically reading the dot code made up of the blocks, restoring means for restoring the information by processing the dot code read by said reading means, and output means for outputting the information restored by said restoring means. <IMAGE>
