Reading means for reading a barcode a plurality of times and obtaining a plurality of barcode image data;
Storage means for storing the barcode image data acquired by the reading means;
Detecting means for detecting a movement state of the reading means in a three-dimensional space during the barcode reading operation;
Based on the moving state detected by the detection means, the barcode image data stored in the storage means is read by the barcode when the reading means is at a reference position preset with respect to the barcode. Correction means for correcting the barcode image data when received,
Combining means for combining the barcode image data corrected by the correcting means to generate combined image data ;
Decoding means for decoding the combined image data generated by the combining means;
A barcode reader. The detection means detects the movement state using a gyro sensor,
The gyro sensor includes: an acceleration sensor that detects an acceleration of the reading unit in a three-dimensional space; and an inclination sensor that detects an inclination of the reading unit caused by the movement of the reading unit in a three-dimensional space. The barcode reader according to 1. Computer
