    摘要： The present invention discloses an elastic transformable body for adjusting vapor pressure, a vapor pressure adjustment chamber using the same, an ink-jet recording head having a vapor pressure adjustment device and an ink-jet recording device having the recording head, and more particularly to a vapor pressure adjustment device for adjusting negative pressure generated in a liquid chamber in an ink-jet recording head when discharging ink. The pressure adjustment chamber has at least one elastic transformation body having a changeable volume according to vapor pressure to adjust the vapor pressure in a container communicated thereto and a support for supporting the elastic transformation body to the container. In the pressure adjustment chamber, the elastic transformation body includes an approximately circular opening and two surfaces approximately flat before transformation at an outer circumference, in which the two surfaces have a shape extended through a curved portion at a front end opposite to the opening.

    摘要： In a liquid ejecting apparatus in which ink is supplied from an ink tank to a print cartridge detachably mounted on a carriage through a tube, connection between an ink needle at a tube side and an interconnecting member at a cartridge side can sealingly be effected positively, and ink supplying and connecting means can be made compact. A closing film having a small hole and a central slit is provided at a tip end of an interconnecting member made of soft material and fitted into an ink flow-in projection portion of the print cartridge into which an ink needle is inserted. Further, a notched needle tip end avoiding configuration is provided at a lower part of a tip end of the projection portion so that abutment between the projection portion and the ink needle can be avoided when the print cartridge is mounted and dismounted, thereby reducing a shifting amount of a needle holding member.

    摘要： A print head of this invention has a plurality of heater boards, and each heater board has a plurality of heating resistors, driver circuits corresponding to the heating resistors, one shiftregister for inputting serial data, a data latch circuit for latching print data input from the shift register, a pre-heat data latch circuit for latching selection data of selecting one or several of pre-heat signals input from the shift register, and a pre-heat selection circuit for selecting one or a plurality of pre-heat signals in accordance with the selection data latched in the pre-heat data latch circuit. In a print operation, one or several of the plurality of input pre-heat signals are selected to pre-heat the heating resistors, and when a main heat signal is input thereafter, the heating resistors are driven in accordance with the print data latched by the data latch circuit, thus performing the print operation.
