7. A thin-substrate inspection method for detecting a stored state of a plurality of thin substrates stored in a storage cassette by use of a camera, wherein the camera is disposed on a thin-substrate transfer robot that transfers the thin substrates, and an image of all of the thin substrates in the storage cassette is picked up by the camera by moving the thin-substrate transfer robot in a vertical direction, thereby detecting a state of the thin substrates.

8. A thin-substrate inspection method for detecting a stored state of a plurality of thin substrates stored in a storage cassette provided with a door by use of a camera, wherein the camera is disposed on a thin-substrate transfer robot that transfers the thin substrates, and an image of all of the thin substrates in the storage cassette is picked up by the camera while moving the thin-substrate transfer robot in a vertical direction synchronously with a driving device for opening the door of the storage cassette, thereby detecting a state of the thin substrates.
