INK TANK, PRINTING HEAD AND INKJET PRINTING APPARATUS

摘要

An inkjet printing apparatus includes a mechanism for opening and closing an ink supply route between an ink tank and a printing head and capable of attaching and removing the ink tank by a horizontal movement. More specifically, a moving member 60 and the communication pipe 51 engaged therewith are moved upward by moving an operation member 70 upward. As a result, the communication pipe 51 moves into an ink lead chamber 16 and a communication channel 52 of the communication pipe 51 comes into communication with the ink lead chamber 16 through its opening. In this way, the ink lead chamber 16 , namely, an ink storage chamber 12 comes into communication with a liquid chamber 50 of a printing head 20 . An ink supply route is opened in this manner. The ink supply route is closed by the reverse operation to that mentioned above.
