Abstract
PURPOSE:To provide said tank suitable for the impulse system ink jet printer to which the top and the bottom of an ink bag is fixed and in which an injection needle is set on the bottom cover, disturbance of ink dropping or absorption of bubbles can be protected. CONSTITUTION:A bag 9 which contains some ink and can transform arbitrarily is set in a cylinder 12 having a top cover 10 and a lower one 11 and the pressure in the tank 8 is balanced with the external pressure by equipping an air hole 22. Supporting the tank 8 on a supporting plate 26, an injection needle 24 is connected with a tube 5 through a supplying point part 27 and the liquid level L in the tank 8 is let to be located on the same plane as an orifice 3 is. The ink is sent to the head 1 through a tube 5. As the upper part of the ink bag 9 is fixed by an ink bag set screw 13 the ink level L in the ink tank 8 cannot fall and in return the side of the bag 9 shrinks toward the central axis and the flown portion of the ink will be supplied.
