PROBLEM TO BE SOLVED: To make it possible to simplify a system structure around a transporting device by providing the device with positioning means for positioning the sheet glass held by a contactless type holding means to a prescribed position. SOLUTION: The positions of suction heads 1, 1,... are the positions where a glass substrate 18 can be held without contact. The glass substrate 18 is held without contact by supplying compressed air to the suction heads 1, 1. The glass substrate 18 is floated from a base by the rising movement of a supporting plate 16 by a robot. The positioning is executed by the following method: The glass substrate 18 is successively moved toward under guide bars 22 by its own weight and the bottom end 18A of the glass substrate 18 is pressed to the under guide bars 22 and 22. Next, the supporting plate 16 is tilted toward an upper arrow by the robot. As a result, the glass substrate 18 is successively moved toward side guide bars 24 and 24 in the state that the bottom end thereof is held supported. The glass substrate is thus pressed and positioned to the side guide bars 24 and 24.
