Abstract: A table moving mechanism includes a table, a slide apparatus including a first base and slide rails, and a lift including a vertical mover to raise and lower the first base. The table is moved in a first direction along the slide rails. The vertical mover raises and lowers the first base so as to move the table in an up-down direction.
