Then, the conveyor belt 452 enters the wafer storage box 5 to pick up wafers. Then, the piston rod of the air cylinder 404 retracts, and the wafers are slid onto the second conveyor belt 6. Repeat this operation until all the wafers in the full-load storage cassette are taken out. The discharging process is the opposite of the feeding process. The first conveyor belt 3 sends the wafers onto the conveyor belt 452 in the transmission mechanism 45.
