Disclosed is a tube pump (1) including a base (20) that holds a drive shaft (21); a rotor portion (30) that rotates with the driving shaft, the rotor portion having a pair of rollers (34a,34b); a casing (40) having a U-shaped internal surface (41) along which an elastic tube (c) is arranged, the casing (40) being mounted on the base (20) so that the casing (40) can slide with respect to the base (20) in a direction parallel to the linear portions (41b,41c); a cover (50) that is rotatably mounted on the casing (40); a moving mechanism including a rack (25) that is formed on the base (20) and a pinion (45) that is fixed to the rotation shaft (44) of the cover (50). The moving mechanism moves the casing (40) to the operating position where the roller (34a,34b) deforms the elastic tube (c) when the cover (50) closes, and the moving mechanis moves the casing (40) to the exchange position where the roller (34a,34b) comes apart from the elastic tube (c) when the cover (50) opens. <IMAGE> |
