Watching the operation of the "Digital Area Counter" (hereafter referred to as DAC) from Koshinsha evokes a sense of wonder. The screws scattered on the tray move in several rows and eventually fall into a box. The DAC captures and counts each screw as it falls using sensors. The screws, falling chaotically through the air, are counted accurately and displayed on the screen. The fact that the screws are not neatly aligned gives it a vibe far from "we are counting." Nevertheless, the DAC produces precise results.
