Coded data reading and recording apparatus

摘要

A code pattern image printed/recorded on a recording medium and adapted to be picked up and read is electronically taken up and read and then processed by a decoder (24) to restore the original data, which is then transformed into an image data of the code pattern image by an encoder (32) and printed/recorded on another predetermined recording medium to reproduce the code pattern image by a printer (34). The code pattern image printed/recorded on the recording medium is made to contain an operation control data for permitting or prohibiting the operation of the encoder (32) and the operation control data is extracted from the code pattern image by an operation control data extracting unit (28) so that encoding operation control section (30) permits or prohibits the operation of the encoder (32) according to the extracted data.
