Abstract
The apparatus includes an outer case (11), a reading window (14) open into the case (ii), an illumination device (16-20) housed within the case (11) and arranged to act on the optical code being read through the window (14), and a detection device (24-28) housed within the case (11) and responsive to light scattered back from the illuminated optical code into the case (11) through the window (14). The detection device includes a light-sensitive element (24) capable of converting light to electric signals representing the light image, and an optical detection path (25-26) from the reading window (14) to the light-sensitive elements (24) having a reflective element (27) therein which effectively splits the optical path into two consecutive path sections (25,26) at an angle from each other, wherein the second path section (26) is deflected from the first path section (25). The illumination device (16-20) is located on the opposite side of the light-sensitive element (24) from the first section (25) of the optical detection path, thereby minimizing the risk of some of the light emitted by the illumination device (16-20) being transmitted directly to the light-sensitive element (24) and creating reading problems.
