Abstract
A transfer apparatus includes a fixed base, a swivel, a lift mechanism for raising and lowering the swivel relative to the fixed base, a swivel mechanism for turning the swivel about a vertical swivel axis, a linear movement mechanism supported by the swivel, and a hand supported by the linear movement mechanism for transportation of a work along a linear horizontal travel stroke. The lift mechanism includes N (N is an integer equal to or greater than 2) lift members arranged for telescopic expansion and retraction relative to the fixed base. The lift mechanism also includes N lift drive mechanisms each for raising and lowering one of the lift members relative to an immediate lower-stage lift member. The swivel is supported by an uppermost one of the lift members. (FIG.)
