PROBLEM TO BE SOLVED: To provide a tray handler for stacking and de-stacking ophthalmic prescription trays. SOLUTION: The tray handler forms a stack area along a conveyor by a plurality of mutually spaced clamp parts, and has a lift plate and first and second actuators. The lift plate is operably arranged in the stack area, and the first actuator operates by linking with the clamp parts, and the clamp parts can move to the inside and the outside to the lift plate by operation of the first actuator. The second actuator operates by linking with the lift plate, and can move in the vertical direction in the stack area by operation of the second actuator. A control device controls these operations by communicating with the first and second actuators. A method of handling the ophthalmic prescription trays is also disclosed. COPYRIGHT: (C)2008,JPO&INPIT
