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.

摘要： A portable automatic code symbol reading system having a laser scanning engine mounted upon the hand of its operator to provide hands-free automatic laser scanning capabilities. The automatic code symbol reading system includes a battery power supply aboard its hand-mounted housing, and a power-conserving control subsystem for conserving the consumption of electrical power during automatic portable laser scanning operations. The control subsystem of the present invention has a plurality of control centers which control the operation of the system components in accordance with preselected system control operations. Each of the control centers is responsive to control activation signals generated by certain of the system components upon the occurrence of predefined conditions. Certain of the control centers are capable of overriding other control centers to provide diverse control capabilities. These control capabilities facilitate execution of intelligent functions and power consumption measures required during automatic, hands-free code symbol reading operations.

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.

摘要： A novel system and method programming the function parameters of programmable bar code symbol readers and scanners, while avoiding the need to couple the data communication port of a function parameter computer system and the programmable bar code symbol reader to be configured. 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 function-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： Disclosed is a fully automatic bar code symbol reading system having an hand-supportable laser bar code reading device. The system has a number of operative states including, an object detection state, bar code presence detection state and a bar code symbol decoding state. During bar code symbol presence detection state, the visible laser scanning beam produced from the hand-supportable device flickers at a rate which improves the visual conspicuousness of the laser scanning beam in the scan field. The flicker characteristics of the laser scanning beam makes it substantially easier for the user to visually align the laser scanning beam with the bar code symbol on the detected object. Consequently, reading bar code symbols is made substantially easier using the automatic laser bar code symbol reading device of the present invention.

摘要： A laser scanner system for producing and projecting a multi-line scanning pattern into a space in which a bar code is to be brought. The system includes plural modular laser scanners, each producing a line scan pattern, but mounted with respect to one another so that the pattern of each scanner is projected into the space to conjoin to form the multi-line pattern. Each module is arranged to receive light reflected off the object to convert that light into electrical output signals indicative of the bars and spaces of the code. The system also include means for decoding the output signals and for providing the decoded signals to some peripheral device, e.g., an electronic cash register or computer. In one embodiment the scanner is located adjacent a conveyor carrying bar coded items to form an automated check-out counter.

摘要： An ultra-compact laser scanner comprising a self-contained housing including a handle portion configured to be readily held within the hand of a person and a short length body portion projecting outward from the handle portion. A subassembly including a laser tube and associated power supply is mounted on a circuit board within the handle and can be readily removed therefrom. A signal processing subassembly is located within the body portion above the handle. A motor and optic system subassembly is also mounted within the body portion and is arranged to direct a beam of laser light from the laser tube through an arc out through a window in the front of the body portion of the housing to sweep across a bar code symbol at which the device is aimed. A beam width adjusting/beam blocking moveable curtain is mounted over the window. Light reflecting off the bar code enters back into the housing through the window, passes through a compact optic path to a photodetector and associated signal processing components so that the bar code scanned is decoded. The device includes a trigger for effecting the scanning operation. The decoded signals are provided via a cable to associated peripheral equipment, such as electronic cash registers, computers, etc.
