    摘要： A line-type liquid ejecting head includes an ejection unit group constituted by a plurality of ejection units each including a plurality of nozzle openings through which droplets of liquid are ejected, a pressure chamber communicating with the nozzle openings, and a pressure generator capable of generating a pressure change in the liquid in the pressure chamber, the liquid being supplied from a liquid source through a liquid supply channel to the pressure chambers and being ejected through the nozzle openings in a form of droplets by the pressure generators. The ejection unit group is sectioned into a plurality of unit blocks each constituted by a plurality of sets of the ejection units. Each of the unit blocks is provided with a block common channel, a distribution channel communicating with the liquid supply channel and the block common channel, and individual supply channels extending from the block common channel to the pressure chambers of the ejection units. The liquid supplied through the liquid supply channel is distributed through the distribution channels to the block common channels and is further supplied from the block common channels through the individual supply channels to the ejection units in the unit blocks. Droplets of the liquid are simultaneously ejected through the nozzle openings provided in the pressure chamber in each ejection unit upon driving of the corresponding pressure generator.

    摘要： A vessel for storing fluid and a device for detecting remaining fluid in the vessel is provided. The vessel is maintained at a pressure less than atmospheric, but in a range not sufficient to overcome the surface tension of fluid remaining in a nozzle. This prevents fluid from escaping out from the nozzle when the tank is maintained at a height equal to or higher than the nozzle orifice. The tank may be formed from an elastic material or may include a biasing member for maintaining the negative pressure. An ink jet printer including an ink tank maintained at a pressure less than atmospheric main include a device for detecting ink remaining in the tank. Opposing walls of the tank may be conductive and upon consumption of ink therein collapse causing a circuit to short for indicating lack of ink in the tank. Alternatively, the device for detecting the remaining ink may include a conductive member mounted on the periphery of the tank which is displaced as the tank collapses. Further, a photosensitive device may be disposed above and below an ink tank formed of a transparent material which indicates lack of ink remaining when light penetrates the ink tank. In another embodiment a second ink chamber is formed inside the ink tank for providing a signal by means of a different color ink which is printed upon consumption of the ink from the main ink tank.
