Abstract:
1. A carrier supporting apparatus for supporting a carrier containing, therein, a plurality of objects to be processed, such that each of said objects to be processed is arranged vertically at an interval in a horizontal attitude, the carrier including multiple sets of supporting stages each arranged vertically at an interval, a pair of left and right side plates, and a horizontal guide rod provided below the lowermost supporting stages for connecting the side plates, each set of the supporting stages being configured to support the periphery of a bottom face of one of said objects to be processed, and a gap between the lowermost supporting stages and the guide rod being narrower than a gap between each adjacent pair of the supporting stages, wherein the carrier supporting apparatus comprises: a placing table adapted for placing the carrier thereon; a lifting member provided such that the lifting member can be raised and lowered relative to the placing table and such that, when raised, the lifting member contacts a bottom face of only a lowermost object of the objects to be processed which is supported on the set of lowermost supporting stages in the carrier, the lifting member raising the lowermost object so as to lift up the bottom face thereof from the lowermost set of supporting stages; and a drive mechanism adapted to drive the lifting member to be raised and lowered, wherein the placing table has an upper plate having a slit-like opening formed therein, the lifting member is configured to be raised and lowered through the opening of the upper plate, and when the lifting member is projected out, to the greatest extent, through the slit-like opening, the lowermost object is raised up to a possibly uppermost level, thereby providing an enlarged gap between the bottom face of the lowermost object and guide rod, wherein the lifting member is swayed between an inclined state and a vertical state by the drive mechanism provided in the placing table, such that a top end thereof is projected out and retracted into the slit-like opening of the upper plate.
