摘要:
The present invention provides a print module, an information processing device, a print system, a print unit, an ink supply unit, a print method and program, all capable of quickly and easily meeting demands for a print medium size change, particularly to increased sizes, while at the same time coping with demands for faster printing speed. To this end, this invention constructs the print heads (811) in the form of print modules (M) so that their ink systems and signal systems are independent among the print modules. Each print module is set with identity information for its identification.
摘要:
Variations in the negative pressure in the print head is minimized by positively controlling the ink supply pressure. For this purpose, the pump (36) and the valve (35) are installed in the ink communication path between the ink tank (40) and the print head (811), and are controlled to adjust the negative pressure applied to the print head (811).

摘要:
An ink-feeding device is provided in which the pressure applied to the ink in the printing head can be adjusted arbitrarily irrespective of the relative positions of the ink container and the printing head. Inside the sub-tank 80, a pressure-adjusting pump 82 is installed for applying a suitable pressure to many nozzles 22Kn of the printing head 22K. This pressure-adjusting pump 82 is placed a little above the bottom face of the sub-tank 80 at a prescribed distance from the bottom face. Thereby the pressure-adjusting pump 82 is immersed in the ink held in the sub-tank 80. A drive unit 83 for driving the pressure-adjusting pump 82 is placed above the sub-tank 80. On the upper wall of the sub-tank 80, an air-vent valve 84 is fixed to bring the inside pressure in the sub-tank 80 to an atmospheric pressure. The inside pressure in the sub-tank 80 is made equal to the atmospheric pressure by opening the air-vent valve 84.

摘要:
There has been room for improvement in terms of increasing the life of display elements which have occurrences of irreversible bright point defects and black point defects and shortened lives of display elements when DMDs, which are reflective display devices, are used in high temperature environments such as being installed in vehicles. In the present invention, a display control means displays a display image in display elements. An illumination control means drives various illumination means in each subframe into which a frame of the display image is temporally divided, by a field sequential system. The frame is provided with a display period in which the display image is displayed in the display elements by the display control means normally driving a plurality of pixels and the illumination control means driving the illumination means and a non-display period in which the display image is not displayed in the display elements by the display control means engaging in non-display period drive of the plurality of pixels and the illumination control means turning off the illumination means.
