PROBLEM TO BE SOLVED: To provide a miniaturized tube pump of high efficiency capable of using a tube having no self-restoring force or a tube of low rigidity, and an inkjet recording device using the tube pump as an ink sucking or supplying means. SOLUTION: This tube pump is composed of a driving shaft 21, a rotary disc 22 as a rotary body fixed to the driving shaft and rotated integrally therewith, an oscillatable tube pressing plate 23, an oscillating means 24 interposed between the rotary disc and the tube pressing plate 23 for oscillating the tube pressing plate, and a tube 25 fixed to a lower face of the tube pressing plate at its upper wall, and fixed to a case or a tube fixing plate at its lower wall, and the tube 25 is successively pressed and collapsed by the oscillating motion of the tube pressing plate 23, and restored to an initial state. |
