PURPOSE:To avoid stopping of injection occurring due to fill-in or air suction by connecting an ink tank to an ink jet head integrally therewith and providing a dry preventing box for preventing dryness of ink in a nozzle housing the ink jet head detached together with the ink tank. CONSTITUTION:In a dry preventing box 23, a tank 25 containing dry preventing liquid is screwed in a pan 26 attached to a case 31 and the dry preventing liquid is infiltrated into a felt 26a laid on the bottom face of the pan 26. A piezo device 27 is stuck to the back side of the pan 26 and a signal is applied to the piezo device 27 so as to vibrate it, so that the dry preventing liquid infiltrated into the felt 26a is made to fly. The tank 25, the felt 26a, the pan 26, and the piezo device 27 constitute a humidifier 24. An ink jet head removed from a printer is housed in the dry preventing box 23, so that drying of an ink 7 in a nozzle which is an exposed part is prevented. |
