ABSTRACT:
An ink-jet printer includes an ink-jet head assembly which has a modular structure. The head assembly includes a generally bathtub-shaped bottom case in which an ink head for ejecting a series of charged ink droplets is mounted and a pair of top and bottom deflection electrodes is also mounted. The head assembly also includes a similarly bathtub-shaped top case which is mounted on the bottom case upside down to define a substantially enclosed space therebetween. The ink head is supported so as to be adjustable in orientation. And, one end of the ink head is supported as a pivotal point so that the other free end may be oriented in any desired direction. In another structure, a print head assembly is detachably mounted on a carriage and the print head assembly includes an inner ink mist absorbing member formed with a slit and formed from a metal. A carriage cover is detachably mounted on the carriage to cover the print head assembly set in position. The carriage cover is provided with an outer ink mist absorbing member formed with a slit and formed from a resin material.
