    • PROBLEM TO BE SOLVED: To enable easier mounting/demounting of a elastic tube on/from a tube pump.
      SOLUTION: The tube pump comprises a base, a casing, a cover, and a rotor part having a driving shaft and a roller for rolling integrally therewith. The casing is formed as a sliding casing which is linked with a rack of the base via a pinion as a opening/closing support of the cover and moved in linkage with the opening/closing operation of the cover. Preferably, a stepped arcuate face of the inner peripheral face of the sliding casing and an annular protrusion of the cover corresponding thereto are formed as a guide means for the elastic tube, or a tube clamp annexed to the insertion side of the elastic tube is formed to be movable closer to or farther from the elastic tube with the opening/closing of the cover. Otherwise, a permanent magnet of the rotor part and a magnetism detecting means opposed thereto are formed as a means for monitoring the rotating condition and acquiring a stop signal from the rotor at its fixed position.
