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： 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 multi-channel scanner having several photodetectors (12a-12d) and several lasers (10a-10d) for scanning along multiple paths (50a-50d) incorporates a separate input channel (26a-26d) for each photodetector. Each channel provides a sequence of data elements representing light reflected from points along the associated scanning path, and the data elements from each channel are stored in separate FIFO buffers (20a-20d). A multiplexer (22) takes data elements from the various buffers so as from a consolidated stream of data elements (80) incoporating the data elements from the various channels. This stream is processed in a single decoder (24) to recover data denoted by the bar code. Use of a single decoder minimizes the cost and size of the system.

摘要： By automatically adjusting the object detection mechanism of a bar code scanner from a long range mode of operation to a short range mode of operation, the scanner will remain capable of detecting and decoding bar codes even if the object detection mechanism repeatedly detects the presence of a background object. The techniques of the present invention commence when the bar code scanner is placed in a position such that the scanner's object detection mechanism repeatedly detects a background object such as a counter top or conveyer belt. The object detection mechanism is set to the long range mode of operation if it is not already so set. In the case of a stand-mounted scanner, a test is performed to ascertain whether or not the scanner is in its stand, and the method will only proceed once the scanner is resting in the stand. Next, the scanner is programmed to wait for a predetermined amount of time, after which the operational mode of the object detection mechanism is changed from the long range mode to the short range mode. At this time, the object detection mechanism no longer detects the presence of the background object. The scanner will now detect any new objects that enter the field of view of the object detection mechanism, and attempt to read any bar codes which may be present

摘要： Bar code symbol reading system with automatic modes of hand-held (i.e., hands-on) and stand-supported (i.e., hands-free) operation. In the hand-held mode of automatic operation, the user initiates laser scanning by simply bringing the object within at least a portion of the scan field of the automatic bar code symbol reading device for automatic object detection and subsequent automatic bar code symbol reading. In the stand-supported mode of automatic operation, a scanner support stand is used to support the automatic bar code symbol reading device relative to a countertop surface so that the scan field is projected away from the scanner support stand and the hand-supportable housing, and extends above the countertop surface permitting the automatic reading bar code symbols on goods passed thereby. This way, during the scanner-supported mode of automatic operation, a bar code symbol on an object of virtually any size can be automatically read when the object is automatically detected in the outwardly projected scan field while the hand-supportable bar code symbol reading device is supported within the scanner support stand.
摘要翻译：具有自动模式（即动手）和支持（即免提）操作的条形码符号读取系统。在自动操作的手持模式中，用户通过简单地将对象放置在自动条形码符号读取装置的扫描场的至少一部分中来进行自动对象检测和随后的自动条形码符号读取来发起激光扫描。在支持自动操作的模式中，扫描器支撑架用于相对于台面表面支撑自动条形码符号读取装置，使得扫描场远离扫描仪支架和手持式外壳，并且在台面上方延伸，允许通过的货物上的自动读取条形码符号。这样，在扫描器支持的自动操作模式期间，当在向外投影的扫描场中自动检测对象时，可以自动读取几乎任何大小的物体上的条形码符号，而手持式条形码符号读取装置支持扫描仪支架。
