Abstract
A data decoding apparatus decodes MH codes having different code lengths in real time and at high speed. The apparatus has an image memory, a tristate buffer group, a parallel to serial converter, code length and run length decode ROMs, and a group if desired. The tristate buffer from which the next code is to be read out can be selected immediately after decoding a given code in accordance with the code length of the given code. The group is used to detect an end of line if an error occurs in a given line. The error can be eliminated with one line.
