摘要： A scanning device for reading indicia of differing light reflectivity, including bar code or matrix array symbols, has a single light emitter, such as a laser or light emitting diode, for generating a scanning light beam to visually illuminate sequential portions of the indicia. A sensor, such as a charge coupled or other solid state imaging device, simultaneously detects light reflected from portions of the indicia and generates an electrical signal representative of the spacial intensity variations the portions of the indicia. The scanning device may also include an ambient light sensor, and a second light emitter for use only in aiming or orienting the scanning device. A photodetector may also be provided to separately detect one symbol virtually simultaneous with the detection of another symbol by the sensor or to provide dual modalities. A method for reading indicia is also provided.

摘要： A miniaturized electro-optical, retro-reflective scanning module. The module has a base, a first circuit board, and a second circuit board mounted substantially orthogonal to the first circuit board. The base supports a light emitter for producing a scanning beam and optical elements for directing and collecting light energy. The emitted beam reflects off a fold mirror onto a reflector mounted on a drive for oscillation. The oscillating reflector, in turn, redirects the beam onto an indicia being read. The reflected light is reflected off the oscillating reflector and directed to the collection mirror before reaching a detector. The detector included in the module senses light reflected from an indicia scanned by the beam. The reflector is driven by an electro-magnetiz driven system, including a flexure and an actuation arm.

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： A hand-held optical reader for reading printed indicia on a remote target includes a light source for generating a scanning light beam and a detector for detecting the light reflected from the printed indicia. The light source and detector are housed within a housing having a window through which the light beam passes from the source to the target for reflection from the target to the detector. The housing includes parallel front and rear faces, each being generally rectangular in shape and having a lower portion and upper portion. The front and rear faces are joined by a substantially planar base face at their lower edges. The window is disposed in the front face with the reader being ergonomically configured so as be comfortably held in the hand of a user, with the user's palm adjacent the rear face to enable the user to direct the scanning light beam at a remote target.

摘要： Optical scanning is established by superimposing the alternating magnetic field of a coil magnet with the permanent field set up by a permanent magnet which surrounds the coil magnet. Both magnets are fixedly secured to a support at one axial end of the magnets and a flexible diaphragm is secured to the other axial end of the permanent magnet. A scanning mirror is effectively attached between the support and the diaphragm. When the coil magnet is activated, the diaphragm is rapidly flexed which causes the movement of the scanning mirror.

摘要： A plurality of the areas of differing light reflectivity of a bar code symbol or the like are simultaneously illuminated using, for example, a beam of light that has an elongate cross-section. The light beam is swept over the symbol to be read in a direction transverse to the elongated dimension of the illuminated region so that a two-dimensional area of the symbol is illuminated over time. The reflected light is sensed by a 1D CCD array. A microprocessor within the scanner provides visual feedback to aid a user in aligning the device, and also provides for a selectable aspect ratio for the image, a selectable image resolution and size, a selectable aspect ratio of the illumination, and a selectable pixel size. All of these options may be programmed within the microprocessor, enabling the device to read a large variety of two-dimensional symbols.
