Claim:
1. A substrate conveying apparatus, comprising: a substrate processing section which defines a horizontal direction; a batch hand that holds a plurality of substrates assuming a horizontal posture piled together in a batch manner; a batch-hand advancing-retreating mechanism that horizontally advances and retreats the batch hand; a one-by-one hand that holds a single substrate assuming a horizontal posture; a one-by-one-hand advancing-retreating mechanism that horizontally advances and retreats the one-by-one hand, independently of movement of the batch hand; a holding base that holds the batch-hand advancing-retreating mechanism and the one-by-one-hand advancing-retreating mechanism; wherein the batch-hand advancing-retreating mechanism includes a pair of batch-hand linear guides supported on the holding base and extending in parallel with each other, and a batch-hand advancing-retreating bracket coupled to the pair of batch-hand linear guides and configured to advance and retreat while holding the batch hand; and wherein the one-by-one-hand advancing-retreating mechanism includes a single one-by-one-hand linear guide supported on the holding base between the pair of batch-hand linear guides and extending in parallel with the pair of batch-hand linear guides, and a one-by-one-hand advancing-retreating bracket coupled to the single one-by-one-hand linear guide and configured to advance and retreat while holding the one-by-one-hand; an elevation mechanism that moves the holding base upwardly and downwardly; and a rotation mechanism that rotates the holding base around a rotation axis line extending in a vertical direction while at least one of said batch hand and said one-by-one hand is holding a corresponding plurality of substrates or a single substrate, said substrates or substrate assuming a horizontal posture.
