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
