A symbology reader employing an area detector and LEDs mounted at various angular orientations on a printed circuit board for illuminating a target object in an object plane. Each of the LEDs is oriented according to a desired beam vector to illuminate a particular area of the object plane so that the sum of the beams produces a desired illumination pattern. In one embodiment, the illumination pattern is selected to be inversely proportional to the sensitivity of the area detector to provide an even response over an entire image area. The individual LEDs are angularly aligned by an alignment board having an alignment aperture for each LED. The LEDs are mounted onto the printed circuit board with their body portions spaced apart from the board and supported by semi-rigid wire leads soldered to the board. Each of the alignment holes of the alignment board is laterally offset slightly from the mounting position of the LED. The LEDs are angularly aligned by moving the alignment board toward the printed circuit board and engaging sidewalls of the alignment holes with the LED body portions to deflect the LEDs toward a desired angular orientation. When the alignment board reaches a selected distance from the printed circuit board with the LEDs deflected to their desired orientation, the alignment board is fixed in place to hold the LEDs in this orientation.

Symbology reader illumination system

A method and window for providing a clean aperture at the reading face of a symbology reader. The window includes a layered structure including laminar sheets of optically transmissive material overlaying a window base and the adjacent laminar sheets. Each laminar sheet is releasably bonded to the window base. In use, when the outermost laminar sheet is damaged, it is peeled away to reveal the clean sheet beneath. In one embodiment, each laminar sheet includes an integral grasping tab projecting outwardly. The grasping tabs in each successive sheet are offset to permit a user to grasp the single tab corresponding to the outermost laminar sheet to peel it away. In one embodiment, a flexible boot covers an edge portion of the window to protect the window structure and retain the laminar sheets from being inadvertently peeled off. In one embodiment, the grasping tabs are replaced with recesses to provide access for gripping subsequent sheets.

Method and apparatus for providing clean aperture through symbology

A symbology reader having a pair of optical sources for producing cursor beams. The cursor beams are emitted from two spaced apart locations on the reader and angled with respect to an image direction of a detector assembly within the reader. The cursor beams intersect at a desired object distance to form a composite image indicating that the reader is positioned an appropriate distance from a target object. In one embodiment, multiple composite images are formed. The composite images are spaced apart to delineate the extent of an object field of the detector assembly. In one embodiment, the optical sources are LEDs concealed beneath a mounting platform and emitting light transversely to the image direction. In this embodiment, turning mirrors redirect the light forward of the reader to form the cursor beams.

A symbology reader having a replaceable window element. The window element is user replaceable and incorporates varying features for varying applications. By removing and replacing a window element, the user may provide a clear, uncontaminated surface through which light may enter or exit the reader. In some embodiments, the window element includes focusing elements for defining a target plane for a detector assembly within the reader. In one such embodiment, the reader also includes additional focusing elements for focusing spotter beams to aid a user in aligning the reader to the defined target plane. The window element also incorporates polarizers and color selected filters for optimizing the reader for specific applications. In one embodiment, the reader includes a protective rubber boot to provide shock protection and to releasably retain the window element in attachment to the reader. In an alternative embodiment, the reader includes a releasable tab to hold the window element in position on the reader.

A latching system for a battery pack of a hand-held, portable electronic device. A primary latch on the front panel of the battery pack releasably engages a retaining shoulder portion within a battery housing to removably secure the battery pack in a fully installed, electrically connected position within the electronic device. Secondary latches are connected to the left and right side panels of the battery pack at a position away from the primary latch. Each secondary latch is adapted to releasably engage a secondary retaining shoulder within the housing to retain the battery pack in a partially removed position. Elongated electrical contacts are connected to the battery pack and provide electrical contact between the battery pack and the electronic as battery pack is moved from the installed position to the partially removed position. A switch coupled to the battery pack detects movement of the battery pack from the installed position. The primary and secondary latches each have an outwardly biased lever arm movably connected to the battery pack and a head member connected to the lever arm. The primary and secondary latches are arranged so the secondary latches are inaccessible until the battery pack is moved to the partially removed position.

A cup-shaped protective boot of a resilient material covers a portion of a battery pack which protrudes out of an interior chamber of a handle of a portable, battery-powered, hand-held device. The handle releasably receives the battery pack, and the protective boot forms an environmental seal for the end of the handle to inhibit the entry of contaminants into the handle. The protective boot forms an extended gripping surface for the handle and provides protection against impact shock.
