Abstract: An apparatus includes a diffusive plate that is substantially perpendicular to the optical axis of an imaging lens arrangement and covers a side face of a solid rectangular defining a volume space within which parts of a scan engine are deposited. The parts of the scan engine including at least the illumination light source, the imaging lens arrangement, an imaging sensor, and a controller for controlling both the illumination light source and the imaging sensor. The diffusive plate includes a first opening to allow light enter the imaging lens arrangement through the first opening. The area enclosed by the boundary of the diffusive plate substantially equal to the area of the side face of the solid rectangular.

Abstract: An optical scanner (600) and method of operating same includes a housing (16) supporting first (34) and second scanning systems (202), the first scanning system for scanning indicia on a target object, the housing defining an interior region of the scanner. The first scanning system comprises one of an imaging camera (208/209) and a laser light source (38) disposed within the housing interior region defining a first field of view for reading indicia located on a target object. The second scanning system (202) comprises a separate imaging camera (602) disposed in the housing interior region for reading auxiliary data from an auxiliary object relating to one or more target objects being scanned, the second scanning system defining a second field of view (604). A locator platform (620) is recessed within the housing for positioning an auxiliary object within the second field of view during use of the scanner.

Abstract: The light seal gasket for using in a barcode reading arrangement includes (1) a skirt region configured to surround the solid-state imager on the circuit board and having a bottom surface for making a light seal with the circuit board, (2) a baffle tube configured for aligning with an opening on the chassis and having a top surface for making a light seal with the chassis, and (3) a diaphragm region configured to be bendable when the chassis and the circuit board are pressed towards each other with the light seal gasket sandwiched in-between.

Abstract: A trigger for initiating reading, and a lightpipe for displaying the results of the reading, together form an integrated molded assembly for installation into an electro-optical reader.

Abstract: A raster pattern for reading bar code symbols is created by successively reflecting a light beam off scan mirrors oscillated respectively by a resonant motor drive and by another motor drive driven synchronously with the resonant drive.

Abstract: A non-retroreflective compact scan module in an electro-optical reader includes a laser light source, a photosensor and an electromagnetic coil mounted at one surface of a printed circuit board. The laser emits a laser beam perpendicular to the board, and is redirected to an oscillatable scan mirror which is magnetically centered to a rest position when the coil is de-energized. Electrical circuitry is mounted at an opposite surface of the board.
