    摘要: A system for automatically controlling mechanized filing equipment including a conveyor for moving one or more article carriers along a predetermined path. Selective carrier positioning for access at a work station is effected by entering appropriate input commands. Corresponding control signals are accordingly initiated that ultimately determine the interval during which the conveyor drive is operative. To this end, coarse and fine control arrangements are interrelated to energize motor drive circuitry and achieve accurate carrier positioning.
