    Abstract: A vacuum type pickup apparatus may include an absorption pad having an absorption inlet for contacting and/or picking up an object. A pad holder may be connected to the absorption pad. The pad holder may also have a vacuum line. A separator may be provided in the pad holder for forcibly releasing the object from the absorption inlet of the absorption pad. During the forcible release of the object, the air around the absorption pad may be drawn into the pad holder, thus reducing or preventing the potential contamination by impurities of the object as well as the equipment around the object. Also, an additional vacuum extinguisher may not be required, thus simplifying the structure of the vacuum type pickup apparatus and reducing installation costs. Furthermore, the object may be picked up and released in a relatively expedient, safe, and accurate manner, despite the suction force of the vacuum that may be maintained in the pad holder.
