ABSTRACT:
A bar code reader and the mirror oscillating system thereof are disclosed herein. The bar code reader is of the type which produces a scanning light beam by oscillating one mirror with a electromagnetic oscillator and a raster scanning device. The raster scanning device includes a non-contact sensor which produces a position signal. The position signal is representative of the location of the raster mirror. The position signal is utilized to adjust the motor drive signal which positions the raster scanning device. The position signal allows the motor a low cost sheet metal stepper motor to be positioned more accurately despite performance degradation over the life of the motor.
