ABSTRACT:
A line-code reader having a deflection instrument with a laser, from which light in a laser-sweep pattern from an electrically controllable reflecting device is transmitted towards a rotating mirror, and via additional stationary mirrors the light is thrown down towards a product with a line-code label which is to be read. The light reflected from the line-code label is scanned by means of a photocell. The controllable reflecting device in the deflection instrument is supplied with electrical signals or voltages of a frequency or modulated with a frequency of or in the vicinity of the resonant frequency or harmonics hereof for the mechanical oscillation system of which the mirror forms a part.
