Stacking apparatus and stacking system

A stacking apparatus comprising:

• a stacking stage having a stacking surface on which a plurality of objects are to be stacked in layers;
• a correction mechanism configured to move the stacking stage in a direction parallel to the stacking surface;
• a driving mechanism configured to move the stacking stage in a direction perpendicular to the stacking surface;
• and
• a linear-motion mechanism that connects the stacking stage and the correction mechanism to each other, the linear-motion mechanism is configured to give freedom of movement in the direction perpendicular to the stacking surface and to constrain movement in the direction parallel to the stacking surface,
• wherein the driving mechanism includes
• a main body part that does not overlap the stacking stage when viewed in the direction perpendicular to the stacking surface, and
• an arm part extending from the main body part and between the stacking stage and the correction mechanism and supporting the stacking stage, the arm part being configured to move in the direction perpendicular to the stacking surface.
