<P>PROBLEM TO BE SOLVED: To provide a driving method of a fluid transport device capable of correctly controlling its cumulative discharge amount. <P>SOLUTION: A fluid transport device 1 comprises a tube 50 having elasticity, a cam 20, fingers 40 to 46 arranged radially from the rotation center P1 direction of the cam 20, a driving rotor 120 that gives a torque to the cam 20, a first detecting unit that detects a rotation angle of the cam 20, a second detecting unit that detects the rotation angle of the driving rotor 120, and a data table showing the relation between the cam rotation angle and the cumulative discharge amount. The driving method of the fluid transport device includes steps of initializing the cumulative discharge amount and the rotation angle of the driving rotor 120 after the rotation is suspended when the cam rotation angle is detected by the first detecting unit, grasping the rotation angle of the cam 20 at the time when the cam rotation angle is detected by the second detecting unit after fluid discharge is started and comparing it with the data table, rotating the cam 20 until its rotation angle reaches the angle that corresponds to the designated cumulative discharge amount, and stopping fluid discharge when the rotation angle reaches the angle that corresponds to the designated cumulative discharge amount. <P>COPYRIGHT: (C)2012,JPO&INPIT |
