Claim Text:
1. A driving apparatus for an analyzing apparatus in which an analyzing device is set, the analyzing device having a microchannel structure for transferring a sample liquid to a measuring chamber located in the microchannel structure by a centrifugal force generated by rotationally driving the analyzing device, the driving apparatus comprising: a turntable for holding the analyzing device in which the sample liquid has been injected; a first drive part including magnetic material, the first drive part configured to rotationally drive the turntable, the first drive part also including at least two stationary magnetic sensors to detect a rotating magnetic field generated by the magnetic material; a second drive part selectively engaged with the turntable to generate reciprocating vibrations on the turntable; and a vibration detecting section configured to select an output signal having a largest amplitude from output signals of the magnetic sensors and calculate a vibration frequency from the selected output signal.
