    • An ink cartridge and an ink cartridge identifying apparatus are provided which reliably allow only standard, proper ink cartridges to be loaded. An ink cartridge to be loaded into a printer is provided which has a predetermined projected and recessed pattern portion formed on an outer surface thereof and which has a first electrode portion arranged on the projected and recessed pattern portion. The first electrode portion is positioned to be selectively engageable with a second electrode portion, which is arranged on a pattern matching portion which is fixed to a press rod arranged on the printer main body. First and second electrode portions are arranged on the projected and recessed pattern portion and the pattern matching portion to be selectively engageable, and an identification signal is generated when matching first and second electrode portions are engaged. The projected and recessed pattern portion and the pattern matching portion may be shaped into characters/symbols, graphics, or the like.
    • 提供一种墨盒和墨盒识别装置,其可靠地仅允许装载标准的适当的墨盒。 提供一种要装入打印机的墨盒,其具有形成在其外表面上的预定的突出和凹陷图案部分,并且具有布置在突出和凹陷图案部分上的第一电极部分。 第一电极部被定位成能够与布置在布置在打印机主体上的按压杆上的图案匹配部分上的第二电极部分选择性地接合。 第一和第二电极部分布置在投影凹陷图案部分和图案匹配部分上以便可选择性地接合,并且当匹配第一和第二电极部分接合时产生识别信号。 投影凹陷图案部分和图案匹配部分可以被成形为字符/符号,图形等。

    • An ink tank cartridge for an ink-jet type recording apparatus is provided. The ink tank cartridge comprises a first chamber and a second chamber formed adjacent the first chamber. A porous member is housed in the second chamber. A partition wall separates the first chamber from second chamber, which communicate through a communication hole therethrough which extends along a portion of the width of the partition wall. An ink supply port extends through a wall of the first chamber and supplies ink to the exterior of the cartridge from the porous member. An air vent is spaced from the ink supply port provides ambient air to the second chamber. The pressure in the first chamber and the second chamber is at a value less than normal atmospheric pressure, and a pressure difference which retains the ink in the first chamber is also maintained between the first and second chambers by the surface tension of the porous member in the vicinity of the communicating hole. The first and second chambers, partition wall, communicating hole, air vent port and ink supply port are positioned and dimensioned so that a pressure difference between the chambers is not maintained as ink is transmitted through the ink supply port, and ink is supplied from the first chamber to the porous member in the second chamber as required until the pressure difference between the chambers is restored.
    • 提供了一种用于喷墨式记录装置的墨盒。 墨盒盒包括邻近第一腔室形成的第一腔室和第二腔室。 多孔构件容纳在第二室中。 分隔壁将第一腔室与第二腔室隔开,第二腔室通过连通孔连通,该连通孔沿分隔壁宽度的一部分延伸。 供墨口延伸穿过第一室的壁,并从多孔构件向墨盒的外部供墨。 空气通道与供墨口间隔开,向第二室提供环境空气。 第一腔室和第二腔室中的压力小于正常大气压力,并且通过多孔构件的表面张力在第一腔室和第二腔室之间保持墨水保持在第一腔室中的压力差 连通孔附近。 第一和第二腔室,分隔壁,连通孔,排气口和供墨口的位置和尺寸设计成使得当油墨通过供墨口传输时,室之间的压差不会保持,并且油墨从 第一室至第二室中的多孔构件,直到两个室之间的压力差恢复。
