Abstract:
A fluid-treatment apparatus for plate-like parts, in which a fluid-treatment plate faces parallelly at least one of two almost parallel surfaces of a plate-like part and a treatment fluid is ejected from the fluid-treatment plate onto the one surface of the plate-like part while rotating the plate-like part to fluid-treat the one surface of the plate-like part, the fluid-treatment apparatus comprising:a plurality of chuck members each having a chuck groove into which an outer periphery of the plate-like part fits, the chuck members being spun on their own axes to assume two states, one of the two states being a chuck state in which the outer periphery of the plate-like part fits in the chuck grooves of the chuck members, the other being a chuck wait state in which the outer periphery of the plate-like part is disengaged from the chuck grooves; a chuck member spin mechanism to spin the plurality of chuck members on their own axes to bring all the chuck members as one piece into the chuck state and the chuck wait state; and a chuck member revolution mechanism to revolve the plurality of chuck members as one piece about an axis to spin the plate-like part chucked by the plurality of chuck members on its own axis.
