Abstract
A transfer device includes a carrying-in area (A) into which a carriage is carried. A positioning mechanism includes left and right rocking arms () that engage with and disengage from the carriage to lift the carriage while holding it from both left and right sides and position it at a predetermined height position in the carrying-in area. A transfer mechanism () transfers an object from between the positioned carriage and a transfer area. With this construction, the rocking arms lift the carriage from both the left and right sides and from the lower side and position the carriage away from a floor surface. The positioning of the carriage is performed during a rocking operation of the rocking arms, whereby the carriage can be easily and highly accurately positioned without being affected by the flatness of the floor surface even if the carriage has dimensional assembly errors.
