Abstract
A fluid transporter which transports fluid by pressing a plurality of radially disposed pressing shafts against a tube held in a circular-arc shape in directions from the inside of the circular-arc shape in accordance with rotation of a rotational pressing plate having a plurality of projections on the outer circumference thereof so as to allow flow of fluid includes: a first detecting section which detects the rotation angle of the rotational pressing plate; a second detecting section which detects the rotation angle of either a driving rotor for giving a rotational force to the rotational pressing plate or a reduction transmission mechanism for connecting the driving rotor and the rotational pressing plate; a data table which shows the relationship between the rotation angle of the rotational pressing plate and a cumulative delivery amount; and a controller which controls the drive of the driving rotor.
