Abstract
A printer device includes a hard member having a nozzle inlet opening between an emission nozzle and an associated pressurizing chamber for establishing communication therebetween or a hard member having a first nozzle inlet opening between an emission nozzle and an associated first pressurizing chamber for establishing communication therebetween or a second nozzle inlet opening between a quantitation nozzle and an associated second pressurizing chamber establishing communication therebetween, so that, if pressure is applied by a pressurizing unit across the pressurizing chamber, first pressurizing chamber or the second pressurizing chamber, the pressure in these pressurizing chambers rises effectively and stably. Since the emission nozzle and the quantitation nozzle are formed in a resin member, these nozzles can be formed with high accuracy in meeting with laser working characteristics for improving reliability and productivity.
