Optical reader comprising support post
First Claim
1. An imaging module comprising:
- a first circuit board;
an image sensor carried by said first circuit board;
a pair of aiming LEDs mounted on said first circuit board laterally relative to said image sensor;
a one piece support assembly having a front and rear comprising a containment section, a forwardly extending retainer section, and a pair of aperture defining members extending laterally from said containment section, wherein a rear of said one piece support assembly is received in abutting relation on said first circuit board so that said containment section encapsulates said image sensor and said aperture defining members are in opposing relation with said aiming LEDs, said aperture defining member having apertures defined thereon for stopping light emitted by said aiming LEDs; and
a second circuit board received in abutting relation with a front surface of said support assembly, said circuit board having a central aperture through which said forward extending retainer section extends when said second circuit board is abutted against said support assembly, and a plurality of illumination LEDs mounted to said second circuit board.

Abstract
An imaging module in one embodiment includes a printed circuit board, an image sensor electrically connected to the printed circuit board, a support assembly for supporting at least one optical element, and an illumination system for generating an illumination pattern onto a target. The illumination system may include illumination light sources and diffusers for diffusing light from the illumination light sources. The module may further include an aiming system having an aiming light source, an aperture for stopping light from the aiming light source, and an optical element for projecting an aiming pattern into target area. Either or both of the illumination and aiming systems may include light redirecting elements such as mirrors or prisms.
