Abstract: An ergonomic single-line compact laser bar code scanning system having a compact housing for hand-held disposition at a counter. The scanning system is automatically-activated and includes a bar code symbol reading mechanism contained within a hand-supportable housing having a manually-activatable data transmission switch formed integrally in the housing. During symbol reading operations, the bar code symbol reading mechanism automatically generates a visible laser scanning pattern for repeatedly reading one or more bar code symbols on an object during a bar code symbol reading cycle, and automatically generating a new symbol character data string in response to each bar code symbol read thereby. During system operation, the user visually aligns the visible laser scanning pattern with a particular bar code symbol on an object (e.g., product, bar code menu, etc.) so that the bar code symbol is detected, scanned, and decoded.
