Abstract
Apparatus and method for measuring unit or remnant lengths of material, calculating the price and developing related sales information adapts to use in a system wherein the measuring and related data entry operations are performed at a plurality of terminals connected to a central computer. Each terminal employs a measuring roller and associated optical-electronic measuring and data processing circuitry. The measuring roller moves bi-directionally to increment or decrement the measure and is adapted for being repositioned to a precise home position at the commencement of each measuring operation. Electronic 'noise' encountered with prior art optical-electronic length measuring and price computation apparatus has been substantially eliminated and operation improved by use of visual and audio cues for the operator.
