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 scanner which can be used at a point-of-sale (POS) station. The scanner provides a confined scanning volume, so as to avoid unintentional scanning of nearby objects that are located outside of this confined scanning volume. This scanner can be operated in an automatic hands-on mode of operation, or also operated as a stationary laser projection scanner in an automatic hands-free mode of operation. A collimated scanning pattern is projected from the hand-supportable device about a projection axis. The collimated scanning pattern intersects the projection axis within a narrowly confined scanning volume so that bar code symbols disposed within this scanning volume can be read omnidirectionally.

摘要： A code symbol reading device includes a portable housing that contains a source of optical energy. This optical energy is projected into a scan field external to the housing and is incident upon a code symbol situated on an object located within the scan field. Optical energy reflected off the code symbol is detected within the housing to produce scan data that is indicative of the detected optical energy. The scan data is processed to detect and decode the code symbol and to produce symbol character data that are representative of the decoded code symbol. A data packet utilizing the symbol character data is constructed and then used to modulate an electromagnetic carrier signal that is transmitted to a base unit. At the base unit, the carrier signal is demodulated and the data packet is recovered. The received data packet is processed to recover the symbol character data, and an acknowledgment signal is generated to acknowledge the receipt of the symbol character data at the base unit.

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： 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.
