Claim:
1. A substrate processing apparatus comprising: a processing block that includes one or a plurality of chambers and a first transport robot; an indexer for carrying in a substrate to and carrying out the substrate from the processing block; and an interface section provided between the processing block and the indexer, wherein each of the one or the plurality of the chambers includes a substrate holder that holds the substrate, and a nozzle that performs processing on the substrate by supplying a processing liquid to the substrate held by the substrate holder; the indexer includes a container platform on which a storing container that stores the substrate is placed, and a second transport robot that transports the substrate between the storing container placed on the container platform and the interface section, the interface section includes an alignment device, wherein the second transport robot is configured to transport the substrate taken out from the storing container to the alignment device, the first transport robot is configured to transport the substrate after alignment by the alignment device to the substrate holder, the alignment device includes: a plurality of holders respectively configured to be rotatable about a rotational center axis in a vertical direction while holding the substrate having a portion for detection substantially in a horizontal attitude, and arranged to line up in the vertical direction; a shaft member having an axis that extends in the vertical direction and provided in common for the plurality of holders; a rotation driver that rotates the shaft member about the axis and is provided in common for the plurality of holders; a plurality of detectors provided to respectively correspond to the plurality of holders, and respectively configured to detect the portions for detection of the substrates held by the corresponding holders; and a plurality of transmission switchers that are provided to respectively correspond to the plurality of holders, and switch selectively to a transmission state in which rotation of the shaft member is transmitted to the corresponding holder, and a non-transmission state in which rotation of the shaft member is not transmitted to the corresponding holder,
