An electronic device includes an electronic circuit board containing a processing element and a vision sensor. A carrier frame is used to support the electronic circuit board. An optical element is positioned over the sensor and supported by the carrier frame. The electronic circuit board is bent to reduce the length, thickness and/or width of the electronic device, without increasing the others of the length, thickness and/or width of the electronic device.

Carrier frame and circuit board for an electronic device

An electronic device includes a threaded spacer and a biasing element to reduce backlash. The threaded spacer includes a thread end point that is offset from the thread start point of the carrier frame. The offset thread ending and starting points create a gap between the threaded spacer and the carrier frame. The biasing element applies a force to the threaded spacer, thereby reducing the backlash between the lens and the carrier frame, while at the same time allowing the lens to be rotated for focus adjustments.

An imager defines a field of view and an optical axis. An illuminator directs illumination towards a region of interest, the region of interest being an intended position of the object. A tapered translucent diffuser is concentrically aligned with the optical axis, and has a first distal end proximate to the imager, and a second distal end proximate to the region of interest. The tapered translucent diffuser includes a darkened region, the darkened region to absorb a portion of the illumination to substantially reduce reflection of the portion of the illumination toward the object. A light guide can be positioned proximate the first distal end and the imager, such that a second illuminator can generate an aimer beam that passes through the light guide to produce an aimer pattern on the object.

A standoff for an optical imaging system includes a base, with a target plate coupled to the base and positioned along a central trajectory of the base. The target plate includes a scan window positioned along the central trajectory of the base. The scan window serves to align the optical imaging system with an optical mark on an object. A machine readable code can be positioned on the target plate, the machine readable code including optical imaging system setting information to be read by the optical imaging system.
