Abstract:
1. An apparatus for withdrawing a plurality of substrates from within a container and transferring the substrates, the apparatus comprising: a plurality of blades on which the plurality of substrates are respectively placed during transferring; a plurality of withdrawing members installed at respective ends of the respective blades to protrude upward from the blades when withdrawing the substrates from the container, wherein at least one withdrawing member of the plurality of withdrawing members comprises a rotating bar and a rotating shaft, one end of the at least one rotating bar being rotatably connected to at least one blade and the other end of the rotating bar being capable of rotating to protrude upward from the at least one blade, and the one end of the rotating bar perpendicularly connected to the rotating shaft, the rotating shaft rotating to cause the rotating bar to protrude from the at least one blade; a driving unit for selectively protruding the withdrawing members from the blades thereby selectively withdrawing one or more of the plurality of substrates from within the container, the driving unit comprising a wire and a driver, one end of the wire being wound around the rotating shaft and the driver for rotating and winding the other end of the wire; and an elastic member connected to the rotating shaft for providing elastic force to bias the rotating shaft such that the rotating bar is in a non-protrusive position with respect to the at least one blade.
