Sorter controller

An improved sorter control system for controlling modular sorting assemblies which receive copy sheets from a duplicating machine and distribute the sheets into bins to form collated sets of document information being reproduced. The control system uses two states of a cam operated switch in conjunction with two contacts of a relay which changes state as a sheet of paper interrupts a light beam in each of the modular sorter assemblies. In this manner both the lead edge and the trail edge of a copy sheet breaking and clearing, respectively, the light beam upon entering a bin are recognized causing an index mechanism which controls the sequence of opening the gates for each of the bins to advance. The gate last opened directs copy sheets to the next modular sorting assembly to continue the sorting operation.

The gate last opened directs copy sheets to the next modular sorting assembly to continue the sorting operation in an expeditious manner.
