Abstract:
1. A transport device comprising: a traveling holding member which can travel while holding a storage container for storing disc-shaped substrates such that the substrates are layered in a vertical direction, said storage container having an opening formed in one side thereof for inserting and removing the substrates; and a move out prevention mechanism that prevents the substrates from moving out of the opening of the storage container held by the traveling holding member; wherein the move out prevention mechanism is provided in the traveling holding member and includes a contacting member which can be moved between a contact position at which the contacting member is in contact with side faces of the substrates stored in the storage container held by the traveling holding member, and a spaced apart position at which the contacting member is spaced apart from the side faces of the substrates, wherein the contact position is set such that the contacting member is located between an end portion closer to the opening and a central portion of the substrates stored in the storage container in a direction along which the substrates are inserted and removed, wherein the traveling holding member includes a holding portion for holding the storage container, and a travel portion which can travel along a travel path and which supports the holding portion such that the holding portion can be moved vertically, wherein the traveling holding member is configured to transport the storage container to a container transport target location by traveling of the travel portion and vertical movement of the holding portion, and wherein the move out prevention mechanism is supported by the holding portion.
