摘要： A bar code symbol reading system includes an apertured housing through which visible light produced by a laser beam in the housing can exit and enter. A scanning mechanism in the housing scans the laser beam across a scan field and a bar code symbol on an object located in the scan field in response to an activation symbol. Laser light reflected from the bar code symbol is directed in the housing to produce scan data representative of the reflected laser light. That data is processed to detect and decode the scanned bar code signal and to produce symbol character data that is representative of the detected and decoded bar code symbol.

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 bar code scanner for stationary disposition at a counter to projecting a scanning pattern comprising first, second, third, fourth and fifth groups of parallel scan line within a relatively narrow, yet diverging, volume, e.g., pyramid, cone, etc., centered about a projection axis. The scanner includes a compact housing mounted on an adjustible base. The housing includes a window, five stationary mirrors, a laser diode, a rotating reflective polygon for sweeping the laser beam from the diode across the mirrors and out a window so that the projection axis is substantially but not precisely perpendicular to the window. The scanner also includes a fixed curved collecting mirror and a concentrating lens to focus light which is reflected off of a bar code to a photodetector. One mirror extends along an axis parallel to the transverse axis to produce the first group of scan lines. The second and third mirrors are disposed opposite each other close to and laterally of the polygon and extending along respective axes at a small acute angle, e.g., 8 degrees, to the longitudinal axis to produce respective ones of the second and third group of scan lines. The fourth sad fifth mirrors are disposed between the second and third reflecting mirrors, respectively, and each extends along a respective axis at a substantial acute angle, e.g., 48 degrees, to the longitudinal axis to produce respective ones of the fourth and fifth group of scan lines.

摘要： A bar code scanner for either fixed or hand-held disposition at a counter. The scanner includes a compact housing including a spherical head with a window and a downwardly protruding stem, and a sliding carriage attached to the base of the stem. The stem and sliding carriage cooperate with arcuate guide rails in the compact base for positioning the window via pivoting the head about a horizontal axis. An omni-directional scanning assembly is mounted in the head and this includes an object detection circuit for detecting and determining the presence of an object within an operative scanning field, a light source for generating a laser beam when an object is within the scanning field, a scanning mechanism for scanning the light beam across the object and its bar code, a photoreceiving circuit for receiving light reflected from the bar code, an A/D converter for generating a digital signal representing the light reflected from the bar code, and processing and control circuitry for decoding the bar coded-information and controlling overall system flow.

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 bar code scanner for stationary disposition at a counter to projecting a scanning pattern comprising first, second, third, fourth and fifth groups of parallel scan lines within a relatively narrow, yet diverging, volume, e.g., pyramid, cone, etc., centered about a projection axis. The scanner includes a compact housing mounted on an adjustible base. The housing includes a window, five stationary mirrors, a laser diode, a rotating reflective polygon for sweeping the laser beam from the diode across the mirrors and out a window so that the projection axis is substantially but not precisely perpendicular to the window. The scanner also includes a fixed curved collecting mirror and a concentrating lens to focus light which is reflected off of a bar code to a photodetector. One mirror extends along an axis parallel to the transverse axis to produce the first group of scan lines. The second and third mirrors are disposed opposite each other close to and laterally of the polygon and extending along respective axes at a small acute angle, e.g., 8 degrees, to the longitudinal axis to produce respective ones of the second and third group of scan lines. The fourth and fifth mirrors are disposed between the second and third reflecting mirrors, respectively, and each extends along a respective axis at a substantial acute angle, e.g., 48 degrees, to the longitudinal axis to produce respective ones of the fourth and fifth group of scan lines.
