    摘要: A sample card transport station moves a test sample card from an incubation station for the card to a transmittance and fluorescence optical station in a sample testing machine. The sample card transport station has a drive belt and an associated stepper motor. The belt supports the card from one side of the card. A ledge having a card slot is disposed above the belt. The card is snugly received within the card slot, and supported from below by the drive belt and rollers for the belt. When the motor turns the belt, the belt grips the card and slides the card along the slot to the optical stations, without any slippage between the belt and the card. This construction provides for precise control over the movement of the card.The fluorescence station has a linear flash lamp that illuminates a column of the wells of the cards simultaneously. A reference detector and dichromatic beam splitter design is used to insure that the fluorescence measurements are independent of lamp output changes over time. A solid reference is mounted to an optical shuttle and moved into the optical path to calibrate the fluorescence photodiode detectors.
