1. A barcode reading device, comprising:
a housing having a window for placing a barcode;
a first modularized assembly disposed in the housing, comprising:
at least one first light source illuminating the barcode;
at least one second light source illuminating the barcode; and
a first frame for disposing and positioning the at least one first light source and the at least one second light source; and
a second modularized assembly disposed in the housing, comprising:
at least one reflective optical element reflecting a light from the barcode;
at least one imaging unit receiving an image of the barcode reflected by the at least one reflective optical element;
a second frame comprising at least one third disposing portion and at least one fourth disposing portion for respectively disposing and positioning the at least one reflective optical element and the at least one imaging unit;
at least one installation plate having the at least one imaging unit disposed thereon; and
a plurality of supporting elements, a plurality of fastening elements and a plurality of elastic elements for disposing the at least one installation plate on the at least one fourth disposing portion, and for adjusting a positional relationship between the at least one installation plate and the at least one fourth disposing portion, thereby adjusting a pitch angle and/or a focal length of the at least one imaging unit,
wherein positions of the at least one first light source, the at least one second light source, the at least one reflective optical element and the at least one imaging unit relative to the window are defined by positioning the first frame and the second frame in the housing.
