1. A liquid suction and discharge system for suctioning liquid from, and discharging liquid to, a container including a plurality of liquid storing portions aligned in a plurality of arrays, the liquid suction and discharge system comprising:
a plurality of nozzles arranged to be positioned relative to the plurality of liquid storing portions of the container aligned in a plurality of arrays;
a container support device for supporting the container;
a nozzle support device supporting the plurality of nozzles in a state in which distal ends of the plurality of nozzles are directed downward and aligned in at least one array;
a suction device configured for suctioning liquid from the plurality of liquid storing portions of the container by applying suction to the plurality of nozzles, and configured for discharging liquid from the plurality of nozzles by releasing the suction applied to the plurality of nozzles; and
an elevation device supporting the nozzle support device in an elevatable manner above the container support device;
the nozzle support device comprising a plate-shaped nozzle support member;
the plate-shaped nozzle support member including drilled through holes in at least one array, the through holes being respectively provided with spherical bearings so that the plurality of nozzles are swingably supported by the spherical bearings using a first part of each nozzle of the plurality of nozzles as a support point;
a moving frame on an upper surface of the plate-shaped nozzle support member and a plate-shaped nozzle inclination member on an upper surface of the moving frame, the moving frame surrounding each nozzle of the plurality of nozzles supported by the nozzle support member and provided so as to be movable in a same direction as or a direction perpendicularly intersecting an array direction of each nozzle of the plurality of nozzles, and the plate-shaped nozzle inclination member is provided in a direction perpendicularly intersecting a direction in which the moving frame is movable;
the plate-shaped nozzle inclination member including a plurality of drilled through holes in an arrangement corresponding to the plurality of nozzles supported by the nozzle support member, and each through hole of the plurality of through holes of the nozzle inclination member is provided with a sliding bearing such that a second part that is separated upward from the first part of each nozzle of the plurality of nozzles by a predetermined distance is slidably supported by the sliding bearing; and
a first motor configured to move the moving frame on the plate-shaped nozzle support member and a second motor configured to move the plate-shaped nozzle inclination member on the moving frame in a direction perpendicularly intersecting a moving direction of the moving frame, such that the moving frame and the nozzle inclination member are moved to incline the plurality of nozzles supported by the nozzle support member in unison with one another.
