Abstract
A code reading device, which converts a bar code displayed on a medium into electric signals by means of a photo-electric converter and outputs them after having decoded them into data, which can be dealt with by an information processing device, wherein there are disposed two memories for storing data decoded, respectively, at the present time and data decoded at the last time and a comparator for comparing the data stored in these memories, and decoded data are transmitted to the information processing device, only when the two data differ from each other so that the amount of outputted data is reduced.
