    摘要： A layer of fruit in random arrangement is passed beneath a row of switch-actuating arms. Each switch serves as an input to a two-stage set-reset flip-flop circuit. A detectable pulse is created by the flip-flop circuit arrangement as a fruit leaves its associated switch-actuating arm providing that the adjacent arms are unactuated, and, consequently, only one pulse will be created for each fruit that passes beneath the row of arms as the last arm thereof drops off of it. The pulse outputs from the various flip-flop circuits are all directed to conventional pulse counting means to give a count of the total number of fruit passing beneath the row of arms.
