Claim Text:
1. A method for driving a fluid transporter which includes a tube, a rotational pressing plate with a plurality of detection markers, a plurality of pressing shafts disposed between the tube and the rotational pressing plate, a driving rotor which gives a rotational force to the rotational pressing plate, a first detecting section which detects a rotation angle of the rotational pressing plate, the method comprising: following a controller receiving a value of a cumulative delivery amount, rotating the rotational pressing plate from a first stopped position and then stopping the rotation at a second stopped position to detect the rotational angle of the rotational pressing plate when the first detecting section detects a detection marker of the plurality of detection markers, a rotation angle between the first stopped position and the second stopped position being less than an angular interval between adjacent detection markers; initialize the cumulative delivery amount and set the second stopped position as a rotational reference position; and rotating the rotational pressing plate from the rotational reference position, and stopping the rotation when the first detection section detects the rotational angle of the rotational pressing plate corresponding with the cumulative delivery amount.
