Mechanism for driving a transporting device having frame

摘要

A mechanism for driving a transporting device having a frame by at least one of human force and a mechanical driving source, comprises a first part (2, 4, 5) rotated relative to the frame by human force and a second part (17 or 18) rotated relative to the frame by driving the mechanical driving source. An outer ring (13), an inner ring (8) and spoke members (11, 12) are integrally formed with a resiliently deformable material so as to connect the first part and the second part. A first permanent magnet (23)and a second permanent magnet (24) are provided on the outer ring, in such a manner that reed switches provided on the frame senses the angular displacement between the first magnet (23) and the second magnet (24) and each revolution of the first magnet (24) and the second magnet (23). The mechanical driving source in response to the signals which relate to the revolutions and angular displacement and are generated by the reed sensors, are controlled by a controller.
