PROBLEM TO BE SOLVED: To provide a restoration device capable of changing suction pressure when ink is sucked. SOLUTION: A valve 50 is arranged in the intermediate portion of a tube 36K to open and close this intermediate portion. The valve 50 has the main body part 52 attached to the tube 36K so as not to squeeze the tube 36K and the moving part 54 moving in the directions shown by arrows E, F within the main body part 52. When the moving part 54 moves in the direction shown by the arrow E, the intermediate portion of the tube 36K is opened as it is. When the moving part 54 is moved in the direction shown by the arrow F, the intermediate portion of the tube 36K is closed (squeezed). |
