PROBLEM TO BE SOLVED: To provide a tube pump for which the pressure loss of an ink feeding passage is reduced, and also, the number of parts is reduced, and the constitution is simplified in an ink feeding system which performs a filling motion and a cleaning motion by an ink pressurization, and to provide an inkjet type recording device using the tube pump. SOLUTION: This tube pump is equipped with a tube having elasticity, an arc-shape guiding member which guides the tube, and at least one piece of a pressing member which presses the tube to the guiding member. At a part of the guiding member, a release section by which the tube can be released without being pressed by the pressing member is provided for the tube pump. By using the tube pump, this inkjet type recording device has such an ink feeding passage which does not have a switching mechanism for the path of the ink feeding passage.
