Scan module for a bar code reader with a magnifying lens
摘要:
A scan module for use in a bar code reader including a base, a light source, a focusing lens, a scan mirror mounted for oscillatory motion relative to the base so as to create a scanner laser beam, and a magnifying lens for magnifying the angle of reflection of a light beam from the light source off the scan mirror.
