PURPOSE:To integrate a plurality of nozzle holes of a recording head of an ink jet type recording device in high density, by mutually adjoining the nozzle holes, by rectilinearly arranging the holes in the horizontal direction, by mutually adjoining a plurality of ink guide grooves and electrostrictive vibrators, and by disposing the grooves and the vibrators so that they cross with a horizontal plane containing each nozzle hole. CONSTITUTION:The nozzle holes 211-2110 of a plurality of nozzles 221-2210 of a recording head of an ink jet type recording device are adjoined in the horizontal direction and arranged on a straight line. Each ink guide groove 231-2310 corresponding to each nozzle hole 211-2110 and electrostrictive vibrators are mutually adjoined, and curvedly disposed as a sine wave form, and the arrangement curve is formed so that the curve cross with a horizontal plane containing each nozzle hole 211-2110. According to such constitution, a utilization rate of space is remarkably improved, and a large number of the nozzles and each head consisting of the ink guide grooves corresponding to the nozzles and the electrostrictive vibrators can be integrated in fixed space in high density. |
