  • Patent number: 8550006
    Abstract: A side buffer includes a bottom portion on which a FOUP may be placed, a restriction portion, an article receiving portion, and a link portion. The restriction portion is movable between a restricting position and a retracted position. At the restricting position, the restriction portion restricts an inclination of the FOUP on the bottom portion. At the retracted position, the restriction portion allows the FOUP to move between the bottom portion and a position directly above the bottom portion. The article receiving portion is disposed so as to receive a force from the FOUP placed on the bottom portion. The link portion moves the restriction portion from the retracted position to the restricting position with the received force.
