ABSTRACT:
A positioning device includes a movable table supported by a rectilinear guide mechanism or rotary mechanism, the movable table being moved by a driving mechanism so as to position a member, to be conveyed, placed on the movable table, with respect to a predetermined site. After the member being conveyed is conveyed to the predetermined site, the conveyed member intimately contacts a stationary table which provides a reference with respect to the attitude of the conveyed member, such that the attitude correction of the conveyed member is attained.
