摘要： To reduce the size and weight of an optical scanner, the present invention provides a mirrorless beam scanning unit. A flexible member, such as a multi-wire, flat, electrical cable is connected to the light emitter. Reciprocation of the light emitter during emission of light by the light emitter causes the light to scan a surface, such as a surface bearing a bar code label. The cable flexes during such reciprocation.

摘要： An optical scanning assembly turns an optical element in opposite circumferential directions about a longitudinal axis along which a light beam from a light source is emitted. The optical element and the light source are mounted on individual supports between which torsion elements are connected. An electrical coil arrangement interacts with a permanent magnet to effect the turning movement.

摘要： A bar code reader capable of working over a wider range of working angle and for a wider range of bar code densities, using improved optics and sensing elements. The optics and sensing elements and/or the associated circuitry are arranged to provide two channels of data derived from the scanned bar code. The two channels have differing resolutions. Analysis of the data from the two channels provides a single decoded result. As the working angle and density vary at least one of the resolutions will be appropriate for sensing all or most of the bar coded data. The data from the channel producing a valid result can be used, or if neither channel produces a valid result by itself, data from each channel can be analyzed and valid portions of the data from both channels combined to produce the single decoded result. The different resolution of the two channels can be provided using different size photodetection areas, e.g., small and large groups of active areas on a sensor array.

摘要： Optical scanning of one- and two-dimensional barcode symbols is carried out first in an aim mode wherein the symbol is scanned using a first scan pattern that is relatively small and dense so as to be visible to the user and thereafter using a second, larger and more robust scan pattern for decoding. During aiming, the symbol is partially decoded to determine type and orientation, and this information is applied to control the angle of the scan pattern produced, the rate at which the scan pattern is increased for optimum decoding, and the ultimate pattern size. Preferred scan patterns, as well as unique scan mechanisms, are described.

摘要： An integrated scanner for scanning a barcode is formed on a common substrate. The scanner may include a micro-machined mirror, a laser diode, and a detector, mounted on a single substrate or several connected substrates. Lenses can be used to focus a laser beam from the laser diode as well as expand a laser beam deflected by the micro-machined mirror. The scanner may also scan a barcode without using a micro-machined mirror by rotating the laser diode.
