ABSTRACT:
A tube pump includes tubes, hooks, tube receivers, three or more fingers, and a drive mechanism. The tubes each include intermediate tubes, connectors, and end tubes. The tubes are attached by engaging the connectors with the hooks provided on upper and lower sides. The intermediate tubes are provided along the tube receivers. Tube press portions of the fingers are provided between the intermediate tubes. The fingers are driven by the drive mechanism so that the tube press portions are reciprocated between a position where one of the intermediate tubes is squeezed and a position where the other of the intermediate tubes is squeezed.
