Abstract:
1. An opener-side door drive mechanism, constituting a part of a substrate container opener for opening and closing a substrate container, the substrate container including a container main body configured to open in a preset front face direction and having a space for containing substrates therein, and a container-side door formed to be attached to and detached from the container main body and adapted to close an opening of the space for containing the substrates therein while being attached to the container main body, the opener-side door drive mechanism being configured to drive and displace an opener-side door capable of holding the container-side door which is removed from the container main body, the opener-side door drive mechanism comprising: (a) a movable body configured to be movable in forward and backward directions X including a forward direction X (b) movable body drive means configured to drive and displace the movable body in the forward and backward directions X; (c) a connector fixed to the opener-side door; (d) a plurality of link members constituting a parallel link mechanism by connecting the movable body with the connector, the plurality of link members being interposed therebetween, wherein the connector is connected with the movable body such that the connector can be relatively and angularly displaced about an angular displacement axis L which extends vertically or substantially vertically to the forward and backward directions X; and (e) link member angular displacement means configured to angularly displace each of the link members relative to the movable body to predetermined angular positions corresponding to positions of the movable body along the forward and backward directions, the link member angular displacement means being configured to:
