Electronic copy selection controls for a document reproduction machine

摘要

A multidigit position control register is set by a new control signal either after being reset to a reference state, after completion of a controlled machine function and receipt of a new control signal or when all digit positions contain significant control signals and a new control signal is received. A document reproduction machine controlled by the control register has enhanced operator convenience and copy throughput by disclosed interactions of such register and machine. It is preferred that a manually actuated keyboard supply the control signals.
