Abstract

PURPOSE:To make the flying speed of ink droplets of each nozzle of a multinozzle jet head uniform by making the length of nozzles, that of a flow route between a nozzle and a pressure chamber and that of the pressure chamber substantially equal by each channel. CONSTITUTION:A plate 1 forming part of an ink chamber is provided with a groove 3 for a pressure formng and absorbing chamber, a recessed portion (groove) 4 for forming a pressure chamber interconnected to the groove 3, a groove 5 for forming a nozzle, a radial groove 6 for connecting the recessed portion 4 for forming a pressure chamber with the groove 5 for forming a nozzle, a hole 7 for receiving ink and a long groove 8 for guiding ink into the groove 3. Said plural recessed portions 4 for forming pressure chambers are all equal in cross-sectional shape and length. The same is also applied to the groove 5 for forming a nozzle and the radial groove 6.
