Patent attributes
Pressure fluctuations that occur inside an ink jet head will be controlled. The ink jet head has a body. A common ink storage chamber is formed inside the body. A plurality of nozzles and a plurality of pressure chambers are formed in the surface of the body. One nozzle corresponds to one pressure chamber, and one pressure chamber corresponds to one nozzle. A plurality of individual ink storage chambers are formed inside the body. Each individual ink path extends from the common ink storage chamber, through one corresponding pressure chamber, and to one corresponding nozzle. The ink jet head is provided with an adjustor that allows the volume of the common ink storage space to increase or decrease. When the pressure of the ink that is stored in the ink jet head fluctuates, the volume of the common ink storage space will increase or decrease, and the pressure fluctuations will be smoothed.
