20120281043Print Carriage - A system and method for depositing a substance onto a continuously moving substrate in first and second transverse swathes, is achieved by providing a print carriage having a first set of inkjet heads and a second set of inkjet heads. The carriage is traversed across the substrate in a forward pass, while depositing the first and second swathes from the respective first and second plurality of inkjet heads and subsequently traversed across the substrate in a reverse pass. The first and second sets of inkjet heads are arranged such that the first and second swathes complement one another on both forward and reverse passes to provide substantially complete coverage of the substrate. In this manner complementary swathes may be deposited from a single head.11-08-2012
20110310176METHOD FOR EJECTING INK DROPLETS ONTO A SUBSTRATE - An ink mixed with spacer members is ejected onto one or both of a TFT substrate and a CF substrate while an ink jet head having a plurality of ink jet nozzles is moved. The excursions of a predetermined number of ink jet nozzles from an end of the ink jet head overlap those of a next excursion of the ink jet head without causing overlapping of ejected ink within the overlapping area. An abrupt stepwise change in the amount of ejected ink is suppressed whereby an uneven gap is suppressed.12-22-2011
20110310175LIQUID DROPLET JETTING APPARATUS - A liquid droplet jetting apparatus includes a jetting head having a jetting surface on which a plurality of nozzles are formed for jetting liquid droplets; a carriage carrying the jetting head and moving reciprocatingly in a first direction along a surface parallel to the jetting surface; and a guide member having a guide surface perpendicular to the jetting surface and extending in the first direction to guide the carriage along the guide surface. The carriage is provided with a fixed slide member fixed to the carriage to slide along the guide surface; a movable slide member arranged apart from the fixed slide member in the first direction to slide along the guide surface and configured to be movable with respect to the carriage in a second direction perpendicular to the first direction; and an angle change mechanism for changing an angle of the carriage relative to the first direction.12-22-2011
20110310174IMAGE RECORDING APPARATUS - There is provided an image recording apparatus including:12-22-2011

20120019592Print head mounting and adjusting mechanism - An improved print head mounting and adjusting mechanism for inkjet printers. The mechanism include a bottom bracket and a base plate, the bottom bracket is installed on the base plate, the bottom bracket can be used for mounting print head, wherein said bottom bracket is supported by two stainless steel round shaft which is mounted on the base plate to provide accurate Y-axis movement and adjustment. Micrometer screw head is used as the adjustment mechanism for fine precision adjustment. The bottom bracket moves along a stainless steel round shaft to prevent deflection while adjusting. The print head and the adjustment mechanism are two separate parts, so exchanging or adjusting it will not damage the print heads. Remounting a print head requires a slight adjustment to reach the desired position reducing labor intensity and making for easier maintenance to the print heads.01-26-2012
