Abstract: An opening/closing structure for a thin plate-conveying container has engagement recesses with which engagement projections are engageable. The engagement recesses are formed facing the engagement projections formed on a cover member of a lid of a rotation plate, both at an engagement rotation position and at a disengagement rotation position. The engagement rotation position is the position of the rotation plate for engagement of an engagement section of a lock member with a container body, and the disengagement rotation position is the position of the rotation plate for disengagement of the lock member from the container body.

Abstract: A wafer carrier positioning structure including a carrier body having a bottom face and a frame body provided in a peripheral part of the bottom face to project downwardly, for housing a wafer therein so that the wafer is parallel to the bottom face. Further, the wafer positioning structure includes a guide member detachably attached to the bottom face of the carrier body, a guide groove provided in the guide member, for engaging with a positioning pin projecting from a mounting face upon mounting the carrier body to the mounting face, so as to guide the carrier body to a regular mounting position, and a locking portion provided in the guide member, locking to an inside face of the frame body while elastically having contact with the inside face.

Abstract: Provided is an opening/closing structure for a thin plate-conveying container, in which engagement recesses (44a, 44a and 44b, 44b) with which engagement projections (43, 43) are engageable are formed as located facing the engagement projections (43, 43) formed on a cover member (25) of a lid (14) of a rotation plate (30), both at an engagement rotation position and at a disengagement rotation position. The engagement rotation position is the position of the rotation plate (30) for engagement of an engagement section (31) of a lock member (28) with a container body (13), and the disengagement rotation position is the position of the rotation plate (30) for disengagement of the lock member (28) from the container body (13).

Abstract: A waver transportable container (1) includes a container body (2), which is capable of storing a plurality of wafers (33) and has one end an opening portion (2a), and a door body (3) capable of fitting to the opening portion (2a) of the container body (2) in a detachable manner; a guide rib (17) for positioning is provided in an outside portion of the door body (2), and a positioning rib (22), which engages with the guide rib (17) to position the door body (3), is provided in an outside portion of the container body (2).
