Fluid transporter and fluid transporter driving method

A fluid transporter comprising:

• a tube,
• a rotational pressing plate that rotates about an axis to deliver fluid through the tube, the rotational pressing plate including a guide slope and a projection and being supported by a first device frame and a second device frame on opposite sides of the rotational pressing plate in a direction of the axis,
• a plurality of pressing shafts disposed between the tube and the rotational pressing plate, the plurality of pressing shafts selectively engaging the guide slope and the projection with the plurality of pressing shafts transitioning from the guide slope to the projection with the plurality of pressing shafts and the tube being moved along the axis towards the rotational pressing plate, the plurality of pressing shafts being supported by a third device frame, the first device frame, the second device frame and the third device frame being aligned with at least one guide shaft extending from the first device frame through the second device frame and the third device frame,
• 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, and
• a controller that controls the driving rotor and the rotational force to the rotational pressing place, the controller controls
• rotation of the rotational pressing plate through a rotation angle corresponding to a designated cumulative delivery amount;
• and
• stops fluid delivery when the rotation angle of the rotational pressing plate reaches the rotational angle corresponding to the designated cumulative delivery amount adjusted by a the calculation unit of the controller.
