Abstract
A pallet changer has a pallet support rotatably provided on a bed and a plurality of pallet inlet/outlets disposed on the edges of the pallet support at regular intervals. Positioning pins are biased such that they project from the bed toward the pallet support. Stops are provided on the pallet support and are engaged with the positioning pins, when the pallet support is turned through an angle corresponding to the angular distance between adjacent pallet inlet/outlets. A control mechanism is provided such that when a pallet is transferred to the pallet support through one of the pallet inlet/outlets, the positioning pin is held disengaged from the corresponding stop until the pallet support is rotated to the next stop position.
