PROBLEM TO BE SOLVED: To make it possible to obtain maximum conveying efficiency with minimum number of vehicles by aligning a plurality of cassette containers in parallel. SOLUTION: A plurality of cassette containers 2a, 2b are aligned in parallel in an automatic conveying vehicle 1 for conveying the cassettes K to a treating unit M1 in the step of manufacturing a liquid crystal display unit. For example, the shown automatic conveying vehicle 1 has two cassette containers 2a, 2b for holding the cassettes K on the upper surfaces. After the vehicle 1 is moved to the unit M1, the treated cassette K mounted on a cassette stage 3 is transferred to the container 2b by a robot arm installed in the vehicle 1. The vacant cassette K1 held in the holder 2a is transferred to the stage 3 of the unit M1. |
