摘要
Optical scanning of barcode symbols is carried out first in an aim mode wherein the symbol is scanned using a first scan pattern that is relatively small and dense so as to be visible to the user, and thereafter using a second, larger, more robust scan pattern for decoding. The preferred scanner module has a scanner mirror which is mounted to a bracket by way of a leaf spring, allowing the mirror to oscillate in one direction. This is hung from a stationary chassis by means of two strips of mylar film, which are themselves protected against mechanical shock by pins which pass through holes in the bracket. The pins provide accurate alignment of the bracket with respect to the chassis.
