摘要： A retractable conveyor individually feeds printed circuit boards from a stack into a processing machine. As the conveyor retracts toward the machine from an extended position over the stack, it cams a releasable pickup device downwardly into gripping engagement with the top board on the stack at a position forward of the stack center. As the conveyor starts to extend again, it cams the pickup device upwardly to lift the engaged board into an inclined position over the stack and in the path of extension of the conveyor, whereupon further extension causes the conveyor to engage the inclined board and separate it from the stack. The pickup device is thereupon released so that the board drops on the conveyor to be carried into the processing machine during the next retraction.
