ABSTRACT:
A scanning arrangement in a scanner which is operative for repetitively scanning indicia having parts of different light reflectivity; for example, such as bar code symbol, and also pertains to the operation of a scanning arrangement of that type at high scanning speeds in two-dimensional or multi-axes scan patterns. A resonance asymmetric scan element (RASE) in which a scan element, which is preferably constituted of a mirror, is in effect attached along the upper side edges thereof to oscillation-imparting spring-means and not at the center of mass of the mirror as heretofore. This allows for higher frequencies of operation for the scan element at lower encountered stresses in that the fast axis of rotation of the scan element or mirror; in essence, the axis of oscillatory rotation about which the mirror is rotated at high frequencies substantially coincides with its center of mass.
