摘要： Disclosed is a fully automatic bar code symbol reading system having an hand-supportable laser bar code reading device which can be used in either an automatic hands-on mode of operation, or in an automatic hands-free mode of operation. The system includes a scanner support frame for supporting the hand-supportable device in a user-selected mounting position, and permits complete gripping of its handle portion prior to its use in the hands-on mode of operation. In general, the hand-supportable bar code reading device has long-range and short-range modes of object detection, bar code presence detection and bar code symbol reading. In the illustrative embodiment, the long-range mode is automatically selected when the hand-supportable bar code reading device is placed within the scanner support stand during the automatic hands-free mode of operation. Whenever the hand-supportable bar code reading device is picked up from the support stand and used in its hands-on mode of operation, the short-range mode is automatically selected to provide CCD-like scanner emulation. When used in either mode of operation, the automatic bar code reading device is capable of reading, in a consecutive manner, one or more bar code symbols on an object, while preventing multiple reading of the same bar code symbol due to dwelling of the laser scanning beam upon the bar code symbol. The automatic bar code symbol reading system of the present invention is disclosed in several different mounting arrangements at a point-of-sale station, illustrating novel methods of reading bar code symbols using the automatic hand-supportable laser scanning device of the present invention.

摘要： An automatic projection laser scanning system for reading bar code symbols. The system is supportable on or above a countertop surface, and includes a laser scanning device having a compact housing from which it automatically produces an object detection field of volumetric expanse for automatic detection of objects, and a scan field including at least one scanning plane for automatic laser scanning of code symbols on detected objects. Both the object detection field and the scan field spatially arranged with respect to each other and the compact housing to facilitate easy scanning of a bar code symbol presented within the scan field after the associated object has been detected within the object detection field, thereby improving the scanning efficiency of the system.

摘要： A novel system and method for programming one or more functional parameters of programmable bar code symbol readers and scanners, while avoiding the need to connect a data communication port of a computer system to a bar code symbol reader that is to be programmed. In a first illustrative embodiment, the function-encoded parameters of a master bar code symbol reader are determined using a computer-based-function-parameter device and subsequently buffered in memory buffer contained therein; the buffered function-encoded parameters are used to produce a list of function-encoded bar code symbols which are printed in a specified reading sequence; and the list of printed-function encoded bar code symbols are read in the specified reading sequence so as to configure the bar code symbol reader with the same set of function-encoded parameters that were programmed in the master bar code symbol reader. In a second illustrative embodiment, the function-encoded parameters of a master bar code symbol reader are determined using a computer based-function-parameter acquisition device and buffered in a memory buffer contained therein; the buffered friction-encoded parameters are used to produce a list of symbol reading instructions, each referencing a specific function encoded bar code symbol on a particular page of a preprinted bar code symbol programming guide, and the list of symbol reading instructions are used to read in a specified order.

摘要： A laser bar code symbol scanner employing a narrow band-pass optical filtering system of novel construction is disclosed. A first optical filtering element is installed in the light transmission aperture of a bar code scanner housing. A second optical filtering element is installed inside the scanner housing near the light detecting element. The first and second optical filtering elements have wavelength selective properties such that taken together they cooperate to form a narrow wavelength band-pass optical filtering system which allows only transmission of light at and around a certain predetermined wavelength into the photodetector element. The present invention also hides aesthetically unappealing electro-optical components mounted in the scanner housing from plain view and the optical filtering elements of the system can be easily and inexpensively manufactured without compromising the performance of the scanner.

摘要： A compact laser scanner for use at a counter, such as a checkout counter, to produce a scanning pattern thereabove and into which a bar code can be inserted to enable the reading of the code. A scanner is of compact height and preferably comprises a housing of a height no greater than approximately six inches and taking up an area of no greater than 150 square inches. The housing includes a top having a horizontally disposed window through which the scanning pattern is projected and indicia for directing the location of the bar code within the scanning pattern. The scanning pattern consists of first, second and third groups of plural scan lines which intersect one another in a common area to produce a star-burst pattern when projected on a plane at approximately 45.degree. to the plane of the window, while intersecting in approximately a triangular configuration when projected on a plane approximately perpendicular to the window. The scanner includes a laser tube, a rotating polygonal reflecting member and plural beam folding mirrors all disposed within the housing. The polygonal reflecting member is arranged to be mounted about a vertical axis. The laser tube is mounted laterally of the polygonal reflecting member and provides a substantially focused beam thereon. The rotation of the reflecting member causes the beam to sweep across the reflecting surfaces, which surfaces fold the beam and direct it out through the window to create the pattern.
