PROBLEM TO BE SOLVED: To obtain an ink jet mechanism which can jet an ink constantly without requiring a variety of density of inks by injecting an ink and a solvent from respective inject ports and mixing them at a specified ratio before being jetted. SOLUTION: A solvent injecting section 3 is disposed contiguously to an ink injection member 1 and provided with heaters 5a-5d and 6a-6d constituting respective injecting members. The injecting members are operated selectively to inject an ink 2 and a solvent 4, respectively, from the injection ports 1a, 3a of the ink injection member 1 and the solvent injecting section 3. Furthermore, a mixing section 7 is provided below the injection ports 1a, 3a in order to mix the ink 2 and the solvent 4 injected from the injection ports 1a, 3a at a specified ratio. An ink jet port 8 is made at the end of tapers 7a, 7b below the mixing section 7 and a heater 9 is provided on the outer circumferential part of the mixing section 7 in order to heat up the mixed ink before being jetted. The ink jet port 8 and the heater 9 constitute a jet section. |
