Scanning arrangement for the implementation of scanning patterns over indicia by driving the scanning elements in different component directions

A method for reading indicia having portions of differing light reflectivity;

• comprising:
• directing a light beam from a scanner component of a scanner towards the indicia;
• collecting reflected light returning from the indicia;
• driving a first and a second vibratory members to angularly oscillate in at least one plane to scan said light beam in at least one scan direction;
• imparting differing signals to alternately drive said first and said second vibratory members said at different respective drive frequencies said to angularly oscillate scanner component in one plane so as to cause said scanner component to implement varying operating modes to generate scan patterns over the indicia;
• and
• rotating said scanner component about a rotational axis simultaneously with the driving of the scanner component.

A scanner for reading indicia having portions of differing light reflectivity;

• comprising:
• means for directing a light beam from said scanner towards said indicia;
• means for collecting reflected light returning from said indicia;
• and
• an arrangement for scanning the indicia with said light beam, said scanning arrangement comprising:
• (i) a scanner component;
• (ii) first and second vibratory means positioned (1) to support said scanner component for angular oscillatory movement;
• (2) to vibrate in first and second orthogonal planes;
• and (3) to cooperate such that vibration in the first orthogonal plane of only the first vibratory means provides fast angular oscillating movement and of only the second vibratory means provides slow angular oscillating movement to said scanner component in a first scan direction and vibration of only said second vibratory means in the second orthogonal plane provides angular oscillating movement to said scanner component in a second scan direction;
• (iii) means for rotating said first and second vibratory means about a rotational axis;
• (iv) read-start means for simultaneously moving said scanner component in said first scan direction and said second scan direction to simultaneously angularly oscillate said scanner component for directing the light beam in said first and second scan directions;
• and
• (v) control means operatively connected to said read-start means for imparting differing signals to said read-start means so as to cause said scanner component to implement varying operating modes to generate scan patterns over the indicia.

method for reading indicia having portions of differing light reflectivity with a scanner comprising the steps of:

• directing a flight beam from said scanner towards said indicia;
• collecting reflected light returning from said indicia;
• and
• scanning the indicia with said light beam by angularly oscillating said scanner in two orthogonal planes to cause simultaneous scanning of said light beam in first and second orthogonal scan directions such that the scanning of the light beam in the first orthogonal scan direction is faster than the scanning of the light beam in the second orthogonal scan direction;
• wherein said scanning is electrically actuated;
• rotating said scanner about a rotational axis simultaneously with the angular oscillating of the scanner;
• and
• controlling the scanning by imparting differing operating signals to implement varying operating modes to generate a scan pattern over the indicia.
