Patent ID: 7722814

Claim:
A centrifugal measuring apparatus comprising a rotary table that is driven by both a motor and a rotor, a biosensor, a retainer that holds on the rotary table the biosensor accommodating a sample inside, an urged contact part that abuts against an electrode of the biosensor with a biased force to establish electrical connection, a measuring part that measures a signal from the electrode of the biosensor, and a connector part that selectively establishes the electrical connection between the urged contact part and the measuring part, wherein, either of the rotary table and the rotor being coaxial with the rotary table has a circular contact along a circumference of a rotary shaft, the circular contact being electrically connected to the urged contact part, the connector part comprises a movable contact that freely comes into contact with and separates from the circular contact at any position on a circle of the circular contact, when the rotary table is rotated, the connector part makes the movable contact to be separated from the circular contact, and centrifugal force generated by rotating the rotary table is applied to the sample within the biosensor, and when the rotary table is stopped, the connector part makes the movable contact and the circular contact to be in contact with each other, and electrical connection between the biosensor and the measuring part is established via the connector part.
