Embodiment Construction

[0020] A preferred embodiment for carrying out the present invention is described below. In the preferred embodiment, the present invention is applied to a linear color inkjet printer. However, the present invention can also be applied to other types of inkjet printers.

[0021] Such as figure 1 As shown, the inkjet printer 1 is provided with a total of eight linear inkjet heads 2 . The two inkjet heads 2K eject black ink, the two inkjet heads 2M eject magenta ink, the two inkjet heads 2C eject cyan ink, and the two inkjet heads 2Y eject yellow ink. The inkjet printer 1 is also provided in figure 1 Transport unit 3 that transports paper in the left direction. Eight inkjet heads 2 in figure 1 line up in the left-to-right direction (along the direction in which the paper is fed).

[0022] An ink ejection surface 2 a is formed on the lower surface of each ink jet head 2 . Such as Figure 5 As shown, in the ink ejection surface 2a of each ink jet head 2, a plurality of hol...

Description

[0001] This application claims priority from Japanese Patent Application No. 2004-084488 filed on March 23, 2004, the contents of which are incorporated herein by reference. technical field [0002] The present invention relates to a cap for an inkjet head mounted on an inkjet printer. Background technique [0003] An inkjet head installed in an inkjet printer is provided with nozzles for ejecting ink. Since the nozzles are exposed to the atmosphere, there is a risk that the ink in the nozzles may dry out and clog the nozzles when the ink is not ejected for a long period of time. In a conventional inkjet head, nozzles are formed on an inkjet surface. Inkjet printers have a cap that fits snugly against the inkjet surface, thus isolating the inkjet surface from the atmosphere. Cover the ink ejection surface with a cap to prevent the ink in the nozzle from drying out. [0004] An example of an inkjet head cap is given in Japanese Laid-Open Patent Application Publication No. ...
