Claims

[Claims for Utility Model Registration] An inkjet printer comprising an inkjet head 1 for ejecting ink droplets from a nozzle, and a tube 12 for supplying ink from an ink cassette 13 to the inkjet head 1, The head 1 is the tube 1.
The tube 12 is provided with a hollow pipe 15 having a protrusion 15a around the outer edge of the tip and sealed with a sealing member 16 at the end thereof, and the tube 12 has a hollow pipe 15 having a protrusion 15a around the outer edge of the tube 12 and the end thereof sealed with a sealing member 16. A hollow needle 17 that punctures the sealing member 16 to supply ink inside the tube; and when the hollow needle 17 punctures and penetrates the sealing member 16, it locks onto the protrusion 15a of the hollow pipe and supplies the ink inside the tube 12. A locking part 18a is provided at the tip for fixing the tube to the hollow pipe 15, and when the locking part 18a is pressed by the protrusion 15a during connection, the rear end narrows the tube 12 and supplies the ink inside the tube. An inkjet printer characterized by having levers 18 facing each other for pressure.
