PURPOSE:To reduce misrecognition by combining a discriminated result based upon a logical code graphic discriminating part and a discriminated result of a discrimination code in a logical code recognizing/deciding part to decide the logical code. CONSTITUTION:Shape data 112 extracted by a logical code graphic extracting part 101 are stored in a logical code graphic storage part 102. A logical code graphic discriminating part 103 discriminates a logical code graphic. A discrimination signal extracting part 104 extracts data indicating the shape of a code written on the inside of the logical code graphic and stores the extracted data in a discrimination code storing part 105. The discrimination code is discriminated by a discrimination code discriminating part 106. A logical code recognizing/ deciding part 107 discriminates the logical code based on the discrimination code discriminated result data outputted from the part 106 and logical code graphic discriminated result data outputted from the part 103.
