FIELD: ink-jet printers, electronic teletypes, facsimile machines. SUBSTANCE: device has housing with set of separate ink-jet heads, which have piezoelectric ceramic element, concentrator of oscillations, injection chamber which has output capillary and is shared by all channels. Injection chamber is shaped as open capillary slit and output holes. Injection chamber of each head is designed as hollow sphere which cover is shifted towards shared injection chamber. Output capillary of injection chamber of each head is coaxial to cover axis of shared injection chamber and is coaxial to corresponding output hole of shared injection chamber. EFFECT: increased resolution, increased speed, isolation of two heads that operate simultaneously. dwg |
