PROBLEM TO BE SOLVED: To provide a liquid matter feeder capable of securely feeding a liquid matter, and in which the liquid matter is hard to be leaked from a liquid matter container even if being removed from equipment.SOLUTION: In a liquid matter feeder comprising: a miso container 6 as a liquid matter container; and a positive displacement pump 7 fitted to the miso container 6 and discharging liquid miso as a liquid matter, the positive displacement pump 7 comprises: an outer tube 32; an inner tube 33 reciprocating so as to be freely retractable in an axial direction to the outer tube 32; a first check valve 41 checking the movement of the liquid miso from the outer tube 32 to the miso container 6; and a second check valve 51 checking the inflow of air from the outside to the inner tube 33, further, since the inner tube 33 is provided with a connection tube part 57 connected to a reciprocation mechanism 91 at the outside, the inner tube 33 of the positive displacement pump 7 is mechanically reciprocated by the reciprocation mechanism 91 at the outside, thus, even in the case liquid miso is fed for a plurality of times in relatively short time, the liquid miso can be securely be fed. |
