Abstract
A flexible member mounts a scanner component for angular oscillating movement relative to a support about an axis in alternate circumferential directions between scan end positions. The scanner component is electromagnetically driven in order to scan a light beam across optically encoded indicia to be read. A permanent magnet is connected to the scanner component and magnetically interacts with an electromagnetic coil so as to impart a force to the magnet and move the scanner component from a rest position to at least one of the scan end positions.
Claims14
An arrangement for reading optically encoded indicia, the arrangement comprising:
- a) a scanner component for scanning a light beam across the indicia to be read, the component being mounted by a flexible element to a support for angular oscillating movement about an axis with respect to the support in alternate circumferential directions between first and second scan end positions;
- b) means for electromagnetically driving the scanner component in the alternate circumferential directions between said first and second scan end positions, said means including a magnet connected to the oscillating scanner component;
- and
- c) an element on the support for magnetically interacting with the magnet so as to impart a force to the magnet and hence move the scanner component from a rest position to at least one of said first and said second scan end positions.
