<P>PROBLEM TO BE SOLVED: To provide a feeder capable of feeding a fluid by a simple structure. <P>SOLUTION: A plurality of projections 4c and 6c are formed at approximately regular intervals in the circumferential direction on the outer periphery of a pair of rotatably supported rollers 4 and 6, and a container 1 is held between the pair of rollers 4 and 6 so that the container 1 can be pressed with the rotation of the rollers 4 and 6. The feeder has transmission mechanisms 16 and 18 to transmit rotation of one roller 4 reversely to the other roller 6. The pair of rollers 4 and 6 are rotated in such a phase state that a plurality of projections 4c in one roller 4 and a plurality of projections 6c in the other roller 6 are alternately brought into contact with the container 1 to press the flexible container 1, so that the fluid loaded in the container 1 is fed. <P>COPYRIGHT: (C)2010,JPO&INPIT |
