摘要:Disclod is a fully automatic bar code symbol reading system having an hand-supportable lar bar code reading device which can be ud 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 ur- lected mounting position, and permits complete gripping of its handle portion prior to its u 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 prence detection and bar code symbol reading. In the illustrative embodiment, the long-range mode is automatically lected 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 ud in its hands- on mode of operation, the short-range mode is automatically lected to provide CCD-like scanner emulation. When ud in either mode of operation, the automatic bar code reading device is capable of reading, in a concutive 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 lar scanning beam
upon the bar code symbol. The automatic bar code symbol reading system of the prent invention is disclod in veral different mounting arrangements at a point-of-sale station, illustrating novel methods of reading bar code symbols using the automatic hand-supportable lar scanning device of the prent invention.
