Abstract:
1. A fluid transporter comprising: a tube; a rotational pressing plate including a body and a gear disposed below the body, the gear having a planar surface transverse to an axis of rotation of the rotational plate and the gear extending radially beyond a radially disposed peripheral surface of the body, the rotational pressing plate having a plurality of rotation reference positions disposed at equal angle intervals in the circumferential direction; 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, the driving rotor having a plurality of other rotation reference positions disposed at equal angle intervals in the circumferential direction, a number of the other rotation reference positions being greater than a number of the rotation reference positions; a reduction transmission mechanism which connects the driving rotor and the rotational pressing plate; a first detecting section which determines a rotation angle of the rotational pressing plate based on detection of one or more of said plurality of rotation reference positions; a second detecting section which determines another rotation angle of the driving rotor based on detection of one or more of said plurality of other rotation reference positions; and a controller, wherein the controller controls an amount of a fluid delivered through the tube based on the detected rotation angle by the controller controlling a rotation of the rotational pressing plate to deliver a desired amount of the fluid; wherein the first detecting section faces the planar surface of the gear of the rotational pressing plate and is adjacent to the rotational pressing plate.
