Abstract:
A scan module for a system for electro-optically reading indicia, comprising:a) a support including a base lying in a first plane, a frame wall having an opening and lying in a second plane elevated and parallel to the first plane, and a raised support wall elevated above the frame wall at a rear side of the support; b) a light source mounted on the support for emitting a light beam; c) a scan mirror mounted on the support for reciprocal oscillating movement to reflect the light beam incident on the scan mirror; d) a drive mounted on the support for reciprocally oscillating the scan mirror to sweep the incident light beam reflected therefrom; and e) a pair of beam-folding reflectors, one of the reflectors being mounted on the raised support wall, and the other of the reflectors being mounted at a front side of the support spaced away from the rear side, the other reflector being operative for reflecting the light beam reflected from the scan mirror through the opening in the frame wall to the one reflector, the one reflector being operative for reflecting the light beam reflected from the other reflector above the frame wall and exteriorly of the support between the rear and front sides thereof toward the indicia to be read.
