Abstract
A code reading apparatus of a bar code reader which has detecting means for outputting a reading signal responsive to the code displayed on a medium, edge detecting means for detecting the edge of the reading signal, counting means for starting counting each edge detected by the edge detecting means. Discriminating means outputs a reset signal to decoding means when the counted value started for counting by the counting means is a product or more of the quotient produced by dividing the allowable maximum width of the code by the allowable minimum width and the counted value counted between the edges immediately before by the counting means, when the quotient produced by dividing the counted value started for counting by the counting means by the counted value counted between the edges immediately before is a quotient or more produced by dividing the allowable maximum width of the code by the allowable minimum width. Thus, the apparatus can discriminate the start even if the starting margin before the code of the bar code is short.
