Abstract: A desk having a pivoting, sliding hidden return mounted atop a drawer pedestal and beneath the desk top. The return is supported upon a rail and pivot mechanism which allows the return to pivot and slide between a closed position beneath the desktop and an open position perpendicular to the desktop. The return includes hinged support legs that are stored flat atop the work surface when stored and are folded down to provide support during use.

Abstract: Electronic solid state circuitry incorporating the microprocessor for automatically controlling document handling apparatus. Sheets are advanced from a stack of sheets arranged in an infeed stacker and are moved one at a time at high speed through an examining location where sensors examine the sheets to determine their condition. The microprocessor periodically initiates an adjustment in the brightness level and gain control level of the lamps and sensor elements employed in the sensor array; tracks each sheet as it moves through the document handling apparatus; and evaluates the outputs developed by the sensors to determine the fitness of each sheet. A gating roller assembly, under control of the microprocessor, is operated to divert each sheet toward one of a plurality of output stackers according to the results of the evaluation performed by the microprocessor.
