Claim Text:
1. An analysis device driving apparatus comprising: a housing having a bottom wall, at least one side wall extending upwardly from the bottom wall and a top opening defined by the at least one side wall; a rotor located in the housing; an analysis device set on the rotor for holding a sample liquid to be centrifugally separated, wherein the rotor is configured to apply a centrifugal force to the analysis device; a door pivotably connected to the at least one side wall of the housing, the door being capable of closing the top opening of the housing and movable between an open state in which the rotor is exposed and a closed state in which the door closes the to opening of the housing and the analysis device set on the rotor is not exposed; a clamper attached to an inner face of the door; the clamper cooperates with the rotor so as to sandwich the analysis device; a holding plate that secures the clamper to the inner face of the door; a flat spring disposed along a radial direction of the rotor, the flat spring is secured to the inner face of the door at one end, the flat spring being positioned to abut an axial end of the clamper and pressing the clamper against the analysis device such that the analysis device is biased against the rotor, when the door is in the closed state; and a protrusion that abuts the flat spring when the analysis device is uplifted and a distance between the analysis device and the rotor is greater than a permissible value, thereby preventing the analysis device from detaching from the rotor.
