The chip dropper is a box-like structure made of acrylic. The two main functions of the chip dropper are to act as a buffer for the chip, and finally drop the chip into the required column as the carriage moves along the game board.
The black acrylic plate has a rectangular cutout, through which the chips fall from the chip feeder. The chip dropper has an aluminum sheet that helps in orienting the chips in the vertical position. A stopper, operated by a servo motor prevents the chips from falling down and rotates by 90 degrees when the chip has to be dropped into the required column. The figure above shows the stopper preventing the chip from falling through.
