PROBLEM TO BE SOLVED: To provide a reader for a barcode or the like capable of accurately judging mountains and valleys whose rise and fall are large as a code with a wide barcode and mountains and valleys whose rise and fall are small as a code with a narrow barcode even though the code has become difficult to read. SOLUTION: Light emitted by a light emitting element 8 is inputted to a card 1, a label, etc., the light reading the barcode 3 of the card 1, the label, etc., is inputted to a computer 13, and the computer 13 has steps P2 to P5 in which the computer 13 judges the mountains and valleys whose rise and fall are large as a code with a side barcode and the mountains and valleys whose rise and fall are small as a code with a narrow barcode. |
