ABSTRACT:
A lens stocking apparatus for stocking lenses includes: a first stage and a second stage, each of which can stack lens accommodating trays in a vertical direction; vertical movement mechanism portions which move the first and second stages in the vertical direction, respectively; and a tray transferring unit which transfers the trays from the first stage to the second stage. The tray transferring unit includes right and left hands for holding the tray which can independently move in a transverse direction. When the tray is transferred from the first stage to the second stage, the tray transferring unit moves the right and left hands in a approaching direction to hold the tray, moves the right and left hands in a direction from the first stage to the second stage to transfer the tray, and moves the first and second hands in a departing direction to releases the tray.
