Claims

[Scope of utility model registration request]

an ink reservoir for storing first and second inks separated from each other; first and second pipes; and the first ink is supplied from the first ink reservoir via the first pipe. a first ink chamber that is supplied with the second ink from the second ink reservoir via the second pipe, and one end of each of which is connected to the first ink chamber. a plurality of first pressure chambers connected to each other and supplied with a first ink; a plurality of second pressure chambers each having one end connected to the second ink chamber and supplied with a second ink; a group of nozzles each having one end connected to each pressure chamber of the first pressure chamber group and the other end opening onto the first surface; a second nozzle group connected to each pressure chamber of the chamber group and having the other end opened on the second surface; a piezoelectric ceramic group fixed to the outer surface and the opposite outer surface near the pressure chamber; selectively driving the piezoelectric ceramic group to apply pressure to the first and second pressure chamber groups; and selectively driving the first and second pressure chamber groups from the first and second nozzle groups. In the inkjet recording apparatus, the first nozzle group and the second nozzle group are separated by a convex portion having a step from the first surface and the second surface. An inkjet recording device characterized in that:
