PROBLEM TO BE SOLVED: To accurately position each tray in a stop position in aligning many continuously transported trays at designated spaces. SOLUTION: In this positioning apparatus for positioning plural trays T in stop positions of an aligning conveyer 2, plural positioning levers 18 are provided corresponding to the stop positions of the respective trays T. Each positioning lever 18 is freely oscillates between a retreat position not interfering with the tray T on the aligning conveyer 2 and an entering position interfering with the tray T on the aligning conveyer 2 by the operation of a cylinder 20. At a height of a small-diameter part T2 of the tray T, the positioning lever 18 is freely oscillated in the horizontal direction parallel to the transport surface of the aligning conveyer 2 or in the substantially horizontal direction thereto. When each tray T reaches a designated position, the aligning conveyer 2 is decelerated and the positioning lever 18 is oscillated from the retreat position to the entering position to accurately position each tray T in each stop position.
