A bar-code reader comprises, a scanner controller (25) that obtains a ratio of a number of modules to a reference module width of a character included as information in a bar code (10), rounds up or off (corrects) the number of modules that includes an error component, when the error amount in the ratio exceeds a permissible value, and demodulates the character, based on a result of the rounding up or off, and a POS controller (31) that makes an operator display (34) display a marked questionable character corresponding to the corrected number of modules, in a result of demodulation by the scanner controller (25), and a keyboard (36) that inputs a correct character based on the display of the operator display (34). With this arrangement, it is possible to read the bar code without applying load to the operator, even if the print precision of the bar code does not satisfy a permissible value.
