Abstract: An ink supply device for a printhead includes an ink cartridge and a damper device. The ink cartridge is connected to the printhead through a flexible tube. The printhead is mounted on a carriage that reciprocates, and discharges an ink drop to perform printing. The damper device is mounted on the carriage to relax pressure fluctuation of ink supplied from the ink cartridge to the printhead. The damper device has a case, an ink introduction passage, and a flexible plate. The case defines a pressure chamber communicated with the printhead. The ink introduction passage is communicated with the flexible tube, and is ated with the pressure chamber. The flexible plate is provided so as to define a part of the pressure chamber, and has a waveform portion formed with a plurality of waveforms.

Abstract: An ink jet head includes a pressure chamber, a main flow path, an actuator, a nozzle, a first communication flow path, and a filter. The pressure chamber is filled with an ink. The main flow path supplies the ink to the pressure chamber. The actuator changes the pressure of the ink filled in the pressure chamber. The nozzle is connected to the pressure chamber and ejects the ink filled in the pressure chamber by driving of the actuator. The first communication flow path connects the pressure chamber to the main flow path. The filter is disposed at a predetermined position between the nozzle and the vicinity of a first boundary of the main flow path and the first communication flow path, and the filter captures an impurity in the ink which has a size larger than the diameter of the nozzle.
