An automatically-activated bar code reading system including: a visible laser light source, scanning element and a plurality of stationary mirrors. When arranged in a first configuration, the visible laser light source, scanning element and plurality of stationary mirrors cooperate to produce a visible omni-directional laser scanning pattern with multiple laser scanning lines having substantially uniform spatial and temporal intensity characteristics at a given scanning plane parallel to a scanning window within a working distance of the system. When the visible laser light source, the scanning element and the plurality of stationary mirrors are arranged in a second configuration, these components cooperate to produce a visible omni-directional laser scanning pattern having temporally varying intensity characteristics, against a single visible laser scanning line having substantially uniform spatial and temporal intensity characteristics, at a given scanning plane parallel to the scanning window within the working distance of the system.

Automatically-activated hand-supportable omni-directional laser scanning bar code symbol reader having a user-selectable linear scanning menu-reading mode supported by a omni-directional laser scanning pattern having temporally varying intensity characteristics for improved bar code symbol navigation and alignment during menu-reading operations

A multi-mode laser-based bar code symbol reading device having a hand-supportable housing with a light transmission aperture, wherethrough visible light can exit and enter the hand-supportable housing. A laser scanning engine, disposed within the hand-supportable housing, is controlled to selectively operate in either an omni-directional reading mode or a uni-directional bar code reading mode. In the omni-directional bar code reading mode, the laser scanning engine projects pattern through the light transmission aperture, an omni-directional laser scanning pattern producing multiple laser scanning lines with substantially uniform spatial and temporal intensity characteristics at any given scanning plane parallel to the light transmission aperture within the working distance of the system, and detects and decodes bar code symbols on objects passing through the omni-directional scanning pattern, and produces symbol character data representative of decoded bar code symbols. In the uni-directional bar code reading mode, the laser scanning engine projects through the light transmission aperture, a visible stroboscopically-pulsed omni-directional laser scanning pattern, against a single laser scanning line having substantially uniform spatial and temporal intensity characteristics at any given scanning plane parallel to the light transmission aperture within the working distance of the system, and detects and decodes bar code symbols on objects passing through the single laser scanning line, and produces symbol character data representative of decoded bar code symbols. A manually-actuatable data transmission switch, integrated with said hand-supportable housing, produces an activation signal in response to the manual-actuation of the data transmission switch. A data transmission subsystem, disposed in the hand-supportable housing, operates under control of control circuitry to communicate the symbol character data produced by the laser scanning engine to a host device operably coupled to the bar code symbol reading device. The control circuitry enables communication of symbol character data produced by the laser scanning engine in the uni-directional bar code reading mode of operation to the host device in response to the activation signal produced by the data transmission switch, and the control circuitry enables communication of symbol character data produced by the laser scanning engine in the omni-directional reading mode of operation to the host device irrespective of the activation signal produced by the data transmission switch.

A laser scanning engine, disposed within the hand-supportable housing, is controlled to selectively operate in either an omni-directional scanning mode or a single line scanning mode. In the omni-directional scanning mode, the laser scanning engine projects an omni-directional scanning pattern through the light transmission aperture, detects and decodes bar code symbols on objects passing through the omni-directional scanning pattern, and produces symbol character data representative of decoded bar code symbols. In the rastered scanning mode, the laser scanning engine projects rastered scanning pattern through the light transmission aperture and detects and decodes bar code symbols on objects passing through the single line scanning pattern, and produces symbol character data representative of decoded bar code symbols. In the single-line scanning mode, the laser scanning engine projects a single line scanning pattern through the light transmission aperture and detects and decodes bar code symbols on objects passing through the single line scanning pattern, and produces symbol character data representative of decoded bar code symbols.

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.
