CHIP FEEDER

The invention provides a chip feeder which can feed chips to accommodating portions arranged on a feed pallet efficiently. The chip feeder includes a feed pallet (10) in which accommodating portions (11), in which chips are to be accommodated, are provided, a suction unit (20) configured to perform suction through the accommodating portions, a vibration application unit (30) configured to apply vibration to the feed pallet, a control unit that is configured and programmed to periodically switch between a state where the suction is being performed and a state where the suction is not performed in a state where the chips have been supplied on the feed pallet, and where the vibration has been applied to the feed pallet. The chips supplied on the feed pallet are to be fed into the accommodating portions by the vibration which is applied to the pallet by the vibration application unit and the suction which is carried out to the accommodating portions by the suction unit. The suction from the accommodating portions and based on the suction unit is performed at least once during one period of the vibration. A negative pressure reaches a maximum range when an amplitude is maximum, and the negative pressure reaches a minimum range when the amplitude is minimum.
