<P>PROBLEM TO BE SOLVED: To provide a liquid conveying device capable of saving a man-hour for replacing tubes. <P>SOLUTION: The device utilizes a tube cassette 40 equipped with a flexible conveying tube 45, a discharge nozzle 41 inserted into one end of the conveying tube 45, a relay tube 47 inserted into the other end, a discharge side holding part 42 in which one end of the conveying tube is coupled to the discharge nozzle to be held and a introduction side holding part 43 in which the other end of the conveying tube is coupled to the relay tube to be held so as to freely detachably mount the discharge side holding part 42 and the introduction side holding part 43 to at least two rollers 61 of a rotating body 14 in which a plurality of rollers 61 are circumferentially arranged at equal intervals in such a manner that the conveying tube 45 of the tube cassette 40 is wound to be extended, and so as to form a blocked space 110 in the conveying tube 45 by the roller 61 pressed to the conveying tube. By so doing, liquid is conveyed by moving the blocked space 110 by rotation of the rotating body 14. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
