ABSTRACT:
A barcode scanner capable of switching the reading resolution of scanning can be used for scanning a barcode with high resolution or low resolution, including a shell body, a scan module and a switchable magnifying module. The shell body has an opening. The scan module arranged in the shell body has a lighting unit emitting an illuminating light onto the barcode through the opening and a sensing unit sensing a barcode image formed from a reflection of the barcode illuminated by the illuminating light passing through the opening. The switchable magnifying module has a magnifier for magnifying the barcode image and a switch unit for switching the position of the magnifier relative to the sensing unit. The switch unit can move the magnifier between an off-axial position, which is not between the sensing unit and the barcode, and an on-axial position, which is between the sensing unit and the barcode.
