摘要： A nozzle orifice protective apparatus comprises a cap for covering an ink nozzle which cap is supplied with maintenance solution, and a maintenance solution tank for storing maintenance solution. The maintenance solution tank is made of a flexible bag and contains a specified volume of gas as well as the maintenance solution, facilitating accurate detection of the amount of solution remaining in the tank. Thus, the maintenance solution tank is simple in construction and inexpensive to manufacture.A water-absorbing polymer is placed a waste collecting tank case so that it absorbs waste liquid such as maintenance solution and ink led from the cap into the tank case. Since the polymer which has absorbed the liquid becomes gel, replacement of the waste collecting tank case and the subsequent waste disposal are extremely simple and easy.

摘要： A nozzle cleaning device blows a cleaning solvent against the nozzle portion of a printer head in an ink jet system printer. The nozzle cleaning device includes an ejecting unit communicated to a cleaning solvent tank through a liquid supply passage. Th ejecting unit includes a plurality of orifices for emitting the cleaning solvent. A side passage is connected to the liquid supply passage. A cylinder is secured to the side passage, and a piston is slidably disposed in the cylinder. When the piston is moved in the cylinder, the cleaning solvent is introduced from the cleaning solvent tank into the cylinder, and then, the cleaning solvent is supplied from the cylinder to the ejecting unit. The amount of the cleaning solvent supplied to the ejecting unit is determined by the stroke of the piston in the cylinder.

摘要： An ink jet system printer includes a capping mechanism for covering a printer head when a carriage is located at a stand-by position. The capping mechanism includes a cap member supported by a slidable plate. The slidable plate is shifted toward the printer head as the printer head moves to the stand-by position through the use of links, whereby the cap member covers the nozzle portion included in the printer head. That is, the slidable plate is shifted by the travelling force of the carriage and, therefore, a separate drive source is not required for the slidable plate.

摘要： An ink jet system printer has a printer head for emitting ink droplets toward a recording paper. Objectional ink mist is inevitably formed and diffused in various directions after the ink droplets impinge upon the recording paper. The printer head includes a first chamber for introducing the ink mist diffused in front of the printer head, a second chamber for accommodating an ink droplet issuance unit for emitting the ink droplets, and a fan system for creating an air flow directed from the first chamber to the second chamber, thereby effectively introducing the ink mist into the first chamber. A filter member is disposed in the first chamber for removing the ink mist introduced into the first chamber. The ink droplet issuance unit is disposed in the second chamber so that a stream of the ink droplets is inclined from a line perpendicular to the surface of the recording paper.
