技术领域 FIELD

本发明涉及容纳墨的墨盒以及使用该墨盒的喷墨打印机。 The present invention relates to an ink cartridge accommodating an ink-jet printer and the ink cartridge. 背景技术 Background technique

已知一种其上安装了容纳墨的墨盒的喷墨打印机,包括探测墨盒中剩余墨量的剩余墨量探测传感器。 It discloses an ink cartridge mounted thereon is accommodated ink jet printer, comprising an ink remaining amount detecting the remaining ink amount in the ink cartridge detection sensor. 例如日本专利No. 2960614的图2 披露了一种这样的传感器,它使用光学传感器,包括发射光的光发射器和接收从光发射器发出并且穿过透明墨盒的光的光接收器。 For example, Japanese Patent No. 2960614 Fig 2 discloses such a sensor which uses an optical sensor comprising a light emitter emitting light and receiving light emitted from the ink container through the transparent emitter and light receiver of the light.

在包括用于探测墨盒中剩余墨量的光学传感器的喷墨打印机中, 光学传感器可能会错误地探测到墨盒中的剩余墨量较少,即使在还没有把墨盒安装到喷墨打印机上时。 Comprising for detecting the amount of ink remaining in the ink cartridge of the ink jet printer of the optical sensor, the optical sensors may mistakenly detect the small remaining amount of ink in the ink cartridge, even when the ink cartridge has not been mounted to the ink jet printer. 当把含有少量墨的墨盒从打印机上取下时,剩余墨量探测传感器不能探测到墨盒已经从喷墨打印机上移走了。 When the ink cartridge contains a small amount of ink removed from the printer, remaining ink amount detection sensor can detect the cartridges are removed from the ink jet printer. 由于喷墨打印机不能确定墨盒是否安装到了打印机上,打印机就可能出现各种误操作,如喷墨等。 Since the inkjet printer can not determine whether the ink cartridge is mounted to the printer, on a variety of misuse, such as ink jet and the like may occur. 为了解决该问题,除了剩余墨量探测传感器外,还可以提供一个探测墨盒是否安装到喷墨打印机上的传感器,这样会增加成本。 To solve this problem, in addition to remaining ink amount detection sensor, but also can provide a sensor to detect whether the ink cartridge is mounted to the inkjet printer, which increases costs.

发明内容 SUMMARY

因此,本发明的一个方面是提供一种墨盒和一种喷墨打印机,其中可以用一个探测器探测墨盒中的剩余墨量和墨盒是否安装到喷墨打印机上。 Accordingly, one aspect of the present invention is to provide an ink cartridge and an ink jet printer in which a detector can be used to detect the remaining ink amount in the ink cartridge and whether the ink cartridge mounted on an ink jet printer. 墨盒可以包括第一探测部分,它定位在墨盒上使得当墨盒安装在成像设备中时成像设备的探测器能够探测第一探测部分,还包括第二探测部分,它定位在墨盒上使得在把墨盒安装到成像设备中或者从成像设备上取下时探测器能够探测第二探测部分。 A first ink cartridge may include a detection portion which is positioned such that when the ink cartridge is mounted on the ink cartridge in the image forming apparatus when the probe of the imaging apparatus capable of detecting the first detection portion, further comprising a second detecting portion which is positioned on the ink cartridge so that the cartridge or mounted to the image forming apparatus capable of detecting the second detection portion when the probe is removed from the image forming apparatus. 第二探测部分可以定位在朝向墨盒的一个表面与第一探测部分分开的位置,其中该表面是指在把墨盒安装到成像设备中的过程中首先插入到成像设备中的一个表面。 The second detection portion may be positioned on a surface facing the ink container is separated from the first position detecting portion, wherein the surface is ink cartridge to the mounting means in the process of the image forming apparatus is first inserted into a surface of the image forming apparatus. 当安装墨盒完成后,探测器能够探测第一探测部分,从而探测墨盒中的剩余墨量。 When installing the ink cartridge is completed, the detector is capable of detecting the first detection portion, so as to detect the amount of ink remaining. 在安装或取下墨盒的过程中,探测器能够探测第二探测部分,从而探测到墨盒是否安装在成像设备中。 Installing or removing the ink container, the detector capable of detecting a second detecting section, so as to detect the ink cartridges are installed in the image forming apparatus. 因此,可以用单独一个探测器探测墨盒中的剩余墨量和墨盒是否安装在成像设备中。 Thus, a single detector can be used to detect the remaining ink amount in the ink container and the ink cartridges are installed in the image forming apparatus. 由于第二探测部分可以定位在朝向墨盒首先插入成像设备的一个表面与第一探测部分分开的位置,在安装完成后,探测器不能探测到第二探测部分。 Because the second detection portion may be positioned on a surface facing the cartridge is first inserted into the image forming apparatus of the first detection section from a position, after installation, the detector can not detect the second detection portion. 可以用能够阻碍探测器的光发射部分发出的光使之不能到达探测器的光接收部分的材料来形成第一探测部分和第二探测部分。 Material of the light receiving part of the light so that it does not reach the detector may be a light emitting portion can block the probe emitted to form a first and a second detection portion detecting section. 因此可以使用非接触型探测器探测剩余墨量(由于消耗它随时间变化)和确定墨盒是否安装在成像设备中。 Thus non-contact type detector may be used to detect remaining ink amount (which varies with time due to the consumption) and determines whether the ink cartridge mounted in the image forming apparatus. 墨盒可以包括一个能够容纳墨的墨盒体。 Cartridge may include a cartridge body capable of holding ink. 墨盒体可以至少部分由具有透光性的材料形成。 Cartridge body may be at least partially formed of a material having translucency. 第一探测部分可以是遮光板,它由基本不透光的材料形成。 The first detection portion may be a light shielding plate which is formed of a substantially opaque material. 遮光板可以可移动地设置在墨盒体中,从而随着墨盒体中墨量的变化而改变位置。 The light shielding plate may be movably provided in the cartridge body, so that as the amount of change in the ink cartridge body changes position. 由于第一探测部分可以是允许光穿过的遮光板,并且它放置在墨盒体中使得它随着墨盒体中剩余墨量的变化而移动,所以就能够探测出由于墨的消耗而随时间变化的剩余墨量。 Since the first detection portion may be a light shielding plate to allow light to pass through, and it is placed in the cartridge body so that it varies the amount of ink remaining in the ink container body is moved, so that it is possible to detect the ink consumption due to the change over time the remaining amount of ink. 由于第二探测部分可以定位在沿着墨盒在安装墨盒的方向上与第一探测部分分开的位置,因此只有在一个预定方向上把墨盒安装到成像设备中或者从成像设备中取下墨盒时探测器才能探测到第二探测部分。 Since the second detection portion may be positioned on the probe along the direction of mounting the ink cartridge in the ink cartridge separate from the first position detecting section, in a predetermined direction so that only the ink cartridge to the image forming apparatus is mounted or removed from the image forming apparatus when the ink cartridge is to detect the second detection section. 当安装结束后,探测器就只能探测到第一探测部分了。 When the installation is complete, the probe can only detect the first detection section. 所以通过避免用探测器探测第二探测部分的复杂操作能够简化安装和取下墨盒的操作。 Therefore, by avoiding complicated operations to detect the second detection portion with the detector can be simplified installation and removal operations of the ink cartridge. 由于安装或取下墨盒的操作变得简单了,就能够避免在安装过程中强度可能比墨盒其余部分低的、暴露出来的第二探测部分由于与墨盒安装部分接触而断裂。 Since the operation of mounting or removing the ink container becomes simple, can be avoided during installation strength may be lower than the rest of the ink cartridge, the second detection portion is exposed due to contact with the cartridge mounting portion is broken. 墨盒可以进一步包括能够容纳墨的墨盒体和覆盖墨盒体在把墨盒安装到成像设备中的过程中首先插入成像设备中的那一端的帽。 Cartridge may further include a cartridge body capable of containing ink and a cap covering the cartridge body that is first inserted into an end of the image forming apparatus during installation of the ink cartridge in the image forming apparatus. 第二探测部分可以是从帽的侧表面向外伸出的伸出部分。 The second detection portion may be a protruding portion protruding outwardly from a side surface of the cap. 伸出部分可以基本不透光。 Projecting portion may be substantially opaque. 在这种结构中,第二探测部分可以形成为结构相对简单的伸出部分。 In this configuration, the second detection portion may be formed as a protruding portion of a relatively simple structure. 在包括第一和第二墨盒的一组墨盒中,第一墨盒的第一最大墨容量可以和第二墨盒的第二最大墨容量不同。 In one set of ink cartridges comprises first and second ink cartridges, a first maximum ink capacity of the first ink cartridge may be an ink and the second maximum capacity of the second ink containers are different. 第一墨盒的伸出部分的形状可以和第二墨盒的伸出部分的形状不同。 Shape of the projecting portion of the first ink container can be shaped portion and a second projecting different cartridges. 一个成像设备可能能够容纳两个或更多个墨盒。 An image forming apparatus may be capable of accommodating two or more ink cartridges. 在这样的实施例中,第一墨盒的最大墨容量可以大于第二墨盒的最大墨容量。 In such an embodiment, the maximum capacity of the first ink cartridge may be greater than the maximum capacity of the second ink cartridge. 第一墨盒和第二墨盒可以包括不同形状的伸出部分(如第二伸出部分)。 The first and second ink cartridges may include projecting portions of different shapes (e.g., a second projecting portion). 因此,探测器探测第一墨盒上伸出部分的方式可以和探测第二墨盒上伸出部分的方式不同。 Thus, the detector detects the projecting portion on the detection mode and a second ink container can be different portions projecting manner on the first ink cartridge. 这样就能够使用伸出部分来确定安装好的墨盒的最大墨容量。 This projecting portion may be used to determine the maximum ink capacity of an installed ink cartridge. 另外,根据探测到的墨盒最大墨容量,可以把墨盒中的剩余墨量输出给如个人计算机等外设。 Further, based on the detected maximum ink capacity of the ink cartridge, you can be the amount of ink remaining output to peripherals such as a personal computer or the like. 墨盒可以包括作为分开的部件的墨盒体和帽。 Cartridges can be included as a separate member cartridge body and a cap. 因此,当墨盒体和帽是分开的部件时,可以以具体成像设备的规格所决定的不同形状来提供帽。 Thus, when the ink cartridge body and the cap are separate members, the shapes may be different specifications of the image forming apparatus specifically determined to provide the cap. 墨盒可以进一步包括一个覆盖至少一部分伸出部分的盖。 Cartridge may further comprise a cap covering at least a portion projecting portions. 这样就能够避免在把墨盒安装到成像设备中或从成像设备中取下时损坏伸出部分。 This makes it possible to avoid damage to the cartridge mounting or removing the image forming apparatus from the image forming apparatus to the extended portion. 在各个示例性的实施例中,成像设备可以包括: 一个墨盒安装部分,它能够安装墨盒; 一个探测器,当墨盒安装在成像设备中时,探测器能够探测第一探测部分,在把墨盒安装到成像设备中或把墨盒从成像设备上取下的过程中,探测器能够探测第二探测部分;和一个控制装置,它根据探测器对第一探测部分的探测计算墨盒中的剩余墨量, 根据探测器是否探测到第二探测部分确定墨盒是否安装到墨盒安装部分中。 In various exemplary embodiments, the image forming apparatus may comprise: a cartridge mounting portion capable of mounting the ink cartridge; a detector, when the ink cartridge is mounted in the image forming apparatus, the detector is capable of detecting the first detection portion in the cartridge mounting to the image forming apparatus or process cartridge is removed from the image forming apparatus, the detector capable of detecting a second detection section; and a control means, the amount of ink remaining in its calculation of the detection probe according to the first detection section, a second detecting section determines whether the ink cartridge mounted to the cartridge mounting portion based on whether the detector detects. 控制装置可以根据探测器对第一探测部分的探测计算墨盒中的剩余墨量。 The control amount of ink remaining in the apparatus may be calculated according to detection of the first detector detecting section. 控制装置还可以根据探测器是否探测到第二探测部分确定墨盒是否安装到墨盒安装部分中。 The control device may further second detection section determines whether the ink cartridge mounted to the cartridge mounting portion based on whether the detector detects. 因此不一定要分别设置探测墨盒是否安装在墨盒安装部分中的探测器和探测墨盒中剩余墨量的探测器。 Thus detection is not necessarily provided, and the ink cartridge detector to detect whether the ink cartridge mounted on the cartridge mounting portion remaining ink amount detector respectively. 这样的结构能够减少生产成本。 Such a configuration can reduce the production cost. 墨盒可以进一步包括: 一个墨容器,它能够容纳墨; 一个供墨通道,墨容器中的墨通过供墨通道能够有选择地提供到墨容器外部的位置,当墨盒安装到成像设备中时,供墨通道能够与连接管配合从而把墨提供给成像设备中的打印头; 一个第一伸出部分,它设在墨盒的外壁上,第一伸出部分沿着该外壁在把墨提供到墨容器外部位置的方向上延伸;和一个第二伸出部分,它设在墨盒的外壁上,第二伸出部分沿着该外壁在把墨提供到墨容器外部位置的方向上延伸,并且用基本不透光的材料形成。 Cartridge may further comprises: an ink container, which can receive ink; an ink

may comprise a second projecting portion. 至少一部分第一伸出部分可以定位在墨盒上,从而在墨盒安装在成像设备中时它置于设在成像设备中的对射式传感器的光发射部分和光接收部分之间。 At least a portion of the first projecting portion may be positioned on the ink cartridge so that ink cartridge is mounted in the image forming apparatus when it is placed between the light emitting portion and a light receiving portion of the beam sensor provided in the image forming apparatus. 至少一部分第二伸出部分可以定位在墨盒上从而在把墨盒安装到成像设备中和从成像设备中取下时,它从光发射部分和光接收部分之间穿过。 At least a portion of the second projecting portion may be positioned on the ink cartridge so that the ink cartridge is mounted to the image forming apparatus, and when removed from the image forming apparatus, which pass between the portion and the light receiving portion of the light emission. 一种喷墨打印机可以包括: 一个能够向记录介质上喷墨的打印头; 和一个能够安装墨盒的墨盒安装部分; 一个具有光发射部分和光接收部分的对射式传感器;和把墨盒中的墨提供给打印头的连接管。 An ink jet printer comprising: an ink jet capable of printing head onto a recording medium; and a cartridge can be mounted to the cartridge mounting portion; a light emitting portion and a light receiving portion having a beam sensor; and the ink cartridges the connection pipe is provided to the printhead. 墨盒安装部分可以构造成使得:在把墨盒安装到喷墨打印机中的过程中, 第二伸出部分在第一伸出部分之前从光发射部分和光接收部分之间穿过;当墨盒安装在喷墨打印机中时,至少一部分第一伸出部分置于光发射部分和光接收部分之间,并且至少一部分连接管与供墨通道配合在一起;并且在把墨盒从喷墨打印机上取下的过程中,在第一伸出部分从光发射部分和光接收部分之间的位置移走后,第二伸出部分从光发射部分和光接收部分之间穿过。 Cartridge mounting portion may be configured so that: during installation of the ink cartridge in the inkjet printer, the second projecting portion and the portion to pass between the light receiving

the sidewall 31 is extended 47a, the ink chamber extends outwardly from the outer surface 48 of the valve seat portion 47b is formed integrally with the side wall 47a so that the upper end of the side wall 47a of pressing radially inwardly extending portion 47. 延伸部分47b的底面与阀体46接触。 The extended portion 47b contacts the bottom surface 46 of the valve body. 利用侧壁47a和延伸部分47b的弹性向下推阀体46。 Using the side walls 47a and 47b extending resilient portion of the valve body 46 is pushed down. 在延伸部分47b的内侧上形成了开口47c,它允许整体形成的侧壁47a和延伸部分47b很容易弹性变形。 Forming an opening 47c, which allows the side walls 47a and integrally formed extended portion 47b is easily elastically deformed on the inner side of the extending portion 47b. 如图5A,5B和6所示,阀体46包括与阀座48接触的底部50,从底部50的周边向墨室31延伸的、大致为圆柱形的阀体侧壁51,和从底部50的大致中心部分向墨室31伸出得比阀体侧壁51高的膜刺破部分52。 As shown in FIG 5A, 5B and 6, the valve body 46 comprises a bottom 50 in contact with the valve seat 48, extending from the periphery of the bottom 50 of the ink chamber 31, a generally cylindrical valve body sidewall 51, and 50 from the bottom a central portion projecting substantially to the ink chamber 31 higher than the valve body side wall portion 51 pierce the membrane 52. 在面对阀座4S的底部50的下侧上形成了向阀座48伸出的环形伸出部分50a。 Forming a projecting portion 50a projecting toward the annular valve seat 48 on the seat facing the underside of the base 50 of the 4S. 推压部分47把阀体46推向阀座48。 Pressing portion 47 of the valve body 46 toward the valve seat 48. 如图5A所示,利用环形伸出部分50a与阀座48上表面的紧密接触,阀体46关闭阀座48 的通孔48a。 5A, using the annular projected portion 50a in intimate contact with the upper surface of the valve seat 48, the valve body 46 closes the valve seat 48 of the through hole 48a. 因此就关闭了供墨通道。 Thus the ink supply passage is closed. 在环形伸出部分50a的外侧同时又在阀体侧壁51的内侧的底部50的一部分上形成了多个连通通道53, 它们形成在把底部50的周边等分的位置。 An annular outer projecting portion 50a at the same time a plurality of communication passages 53 are formed in the inside bottom portion of the side wall 51 of the valve body 50, which is formed at a position outside the bottom 50 of the aliquot. 例如,在本实施例中,在底部50上形成了八个连通通道53。 For example, in the present embodiment, formed on the bottom 50 of the communication passage 53 eight. 如图5A、 5B和6所示,膜刺破部分52包括四个板件52a-52d, 在平面图中它们以大致十字形放在一起。 As shown in FIG. 5A, 5B and 6, the film 52 includes four plate portion piercing members 52a-52d, to place them in a plan view with a substantially cruciform. 膜剌破部分52位于底部50 的大致中心部分。 Membrane pierced portion 52 is located substantially in the central portion of the bottom 50. 在相邻的板件52a-52d之间设有在垂直方向上延伸的槽54。 Between the adjacent plate members 52a-52d is provided with grooves extending in the vertical direction 54. 膜刺破部分52经过形成在延伸部分47b内侧上的开口47c向上伸出。 After piercing the membrane portion 52 projecting portion 47b is formed on the inner side of the opening extending upwardly 47c. 如图4所示,膜刺破部分52的尖端所处的位置比薄膜部分39 略低。 Position, the membrane piercing tip portion 52 which is slightly lower than the film portion in FIG. 4 39. 如图5B所示,当把墨盒3安装到保持器4上时,设在保持器4 上的供墨管12插入引导孔49a,这样供墨管12的尖端就抵抗推压部分47的推压力把阀体46升起。 As shown, when the cartridge 3 is mounted to the holder 4, is provided on the holder 4 5B of the ink supply tube 12 inserted into the guide hole 49a, so that the tip of the ink supply tube 12 on the pressing force against the pressing portion 47 the valve body 46 rises. 因此,阀体46在使得推压部分47变形的同时向上移动,从而阀体46的环形伸出部分50a离开阀座48。 Thus, the valve body 46 so that the urging portion 47 is moved upward while being deformed, so that the valve body 46 an annular protruding portion 50a from the valve seat 48. 这时, 向上移动的阀体46的膜刺破部分52用它的尖端刺破薄膜部分39。 At this time, the membrane valve body 46 moves upwardly with its piercing portion 52 of the tip portion 39 piercing the membrane. 因此,如图4和5B所示,墨室31中的墨经过形成在圆柱形部分38中的连通通道流入阀室32。 Accordingly, and as shown in FIG. 4, the ink in the ink chamber 31 through the cylindrical portion 5B is formed in the communication passage 38 flows into the valve chamber 32. 然后墨流入阀体46的连通通道53并且经过供墨管12流向打印头2。 The ink then flows into the communication passage 53 of the valve body 46 and an ink supply tube 12 flows through the print head 2. 这时阀室32起到供墨通道的作用并且在阀室32中出现来自墨室31的向下墨流动。 In this case the valve chamber 32 functions as the ink supply passage and ink flows downwardly from the ink appears chamber 31 in the valve chamber 32. 空气引导阀22包括阀壳45和容纳在阀壳45中的阀体46。 Air pilot valve 22 includes a valve body housed in the housing 45 and the housing 45 of the valve 46. 空气引导阀22与供墨阀21具有基本相同的结构。 An air valve guide 22 and substantially the same structure as the ink supply valve 21 has. 即推压部分47向下推动的阀体46与阀壳45的阀座48紧密接触,使得阀体46关闭通孔48a。 That pushes down the pressing portion 47 of the valve body 46 and the valve seat 48 of the housing 45 into close contact, such that the valve body 46 closes the through hole 48a. 当墨盒3安装到保持器4上时,空气引导管13插入形成在阀壳45中的引导孔49a。 When the ink cartridge 3 is mounted on the holder 4 when the guide hole is formed in the valve 13 is inserted into the housing 45 of the air guide 49a. 类似于供墨阀21,空气引导阀22的阀体46向上移动, 并且膜刺破部分52刺破圆柱形部分41的薄膜部分42。 Similar to the ink supply valve 21, the valve body 22 of the air guide 46 is moved upward, and the film piercing portion piercing the membrane 52 of the cylindrical portion 41 of the section 42. 从而空气经过阀体46的连通通道53从空气引导管13流入阀室33。 So that the air communicating passage 46 through the valve body 53 of the guide 13 from the air pipe 33 flows into the valve chamber. 空气经过圆柱形部分40、 41和圆柱形部件43的内部通道引入墨室31的上部。 Air passes through the cylindrical portion 40, the cylindrical member 41 and the internal passage 43 is introduced into the upper chamber 31. 如图4所示,遮光机构23放置在墨室31的下部。 4, the light shielding mechanism 23 is placed in the lower chamber 31. 遮光机构23包括不透光型遮光板60,光不能穿过遮光板60,还包括空心浮子6K连接遮光板60和浮子61的连接件62,以及放置在分隔壁30的上表面上并且可转动地支撑连接件62的支撑件63。 The light shielding means 23 comprises an opaque shade plate 60, the light can not pass through the shielding plate 60 further comprises a hollow float 6K connection member 60 and the light shielding plate 61 of the float 62, and placed on the upper surface of the partition wall 30 and rotatable supporting the support member 63 of the connecting member 62. 连接件62在其一端设有遮14光板60,在其另一端设有浮子61。 Connecting member 62 at its one end 14 provided with the light shielding plate 60, a float 61 is provided at the other end. 放置连接件62使得它在平行于图4 纸张的垂直平面中绕设在支撑件63上的枢轴点转动。 Connecting member 62 is placed such that it is in a vertical plane parallel to the sheet of FIG. 4 wound on the support member 63 of the pivot point. 遮光板60是具有预定面积的薄板件,并且把它放置在与图4的纸张平行的垂直表面中。 The light shielding plate 60 is a thin plate member having a predetermined area, and placing it on a vertical surface parallel to the sheet of FIG. 4. 当墨盒3安装到保持器4上时,设在保持器4 上的传感器14的光发射部分14a和光接收部分14b与形成在墨盒体20 侧壁上的伸出部分34处于基本相同的高度。 When the ink cartridge 3 is mounted to the sensor holder 4, the holder 4 provided on the light emitting portion 14a and the extended light receiving portion 14b formed on the side wall 20 of the cartridge body portion 34 at substantially the same height of 14. 当遮光板60位于伸出部分34的内部空间中时,遮光板60阻碍从光发射部分14a发出并且穿过透明墨盒体20的壁和墨室31中的墨的光。 When the light shielding plate 60 in the extended portion of the internal space 34, the light shielding plate 60 hinder emitted from the light emitting portion 14a and the light passing through the transparent wall 31 of the ink cartridge and the ink chamber body 20. 浮子61大致为圆柱形, 它内部充满空气。 The float 61 is substantially cylindrical, its interior filled with air. 整个浮子61的比重小于墨室31中的墨的比重。 The proportion of the entire float 61 is smaller than the specific gravity of the ink in the ink chamber 31. 在墨室31中剩下的墨量较大并且设在连接件62 —端的浮子61完全在墨中的状态下,因为浮子61由于浮力漂浮,如图4中的实线所示, 设在连接件62另一端的遮光板60位于伸出部分34中阻碍光发射部分14a发出的光的位置。 Large amount of ink remaining in the ink chamber 31 and is provided in the connecting member 62 - terminal 61 completely float in the ink state, because the buoyancy of the float 61 floats, the solid line shown in FIG. 4, provided in connection the other end 62 of the light blocking member 60 in the extended plate portion 34 for blocking position of the light emitted from the light emitting portion 14a. 在墨室31中剩下的墨量减少并且一部分浮子61从墨室31中墨所处的水平面处暴露出来的状态下,由于施加给浮子61的浮力变小,浮子61向下移动。 The reduction in the ink chamber 31 and the amount of ink remaining portion of the float 61 is exposed from the ink level of the ink chamber 31 located at the state, because the buoyancy applied to the float 61 decreases, the float 61 moves downward. 因此,如图4中的点划线所示,遮光板60移动到伸出部分34上面的位置,在该位置遮光板60不阻碍来自光发射部分14a 的直射光。 Thus, the dot-dash line in FIG. 4, the light shielding plate 60 moves to a position above the protruding portion 34, the position of the light shielding plate 60 does not inhibit the direct light from the light emitting portion 14a. 因此,来自光发射部分14a的直射光以大致笔直的光路穿过具有透光性的伸出部分34,并且由光接收部分14b接收。 Therefore, direct light from the light emitting portion 14a is a substantially straight optical path through the projecting portion 34 having a light-transmitting, and received by the light receiving portion 14b. 这样传感器14就探测到墨室31中的剩余墨量较少了。 So that the sensor 14 can detect the remaining amount of ink in the ink chamber 31 a little. 与墨盒体20不同,帽24用不具有透光性的材料形成。 Different ink cartridge body 20, a cap 24 having no light-transmitting material. 如图2A到4所示,帽24利用例如超声焊接固定到墨盒体20上,同时覆盖住墨盒体20的下部。 2A to FIG. 4, the cap 24 is fixed by, for example ultrasonic welding to the cartridge body 20 while covering the lower portion of the print cartridge body 20. 在帽24的底部与供墨阀21和空气引导阀22对应的位置形成了圆形伸出部分65。 22 corresponding to a position at the bottom of the ink supply valve 21 and air cap 24 of the pilot valve 65 is formed a circular protruding portion. 当把墨盒3放置在如桌子上时,由于具有圆形伸出部分65,粘在供墨阀21或空气引导阀22的通口或引导孔49a 附近的墨就不大可能粘到桌子上。 When the ink cartridge 3 is placed on a table, such as, since the circular projecting portion 65, the guide stick port valve 22 in the ink supply valve 21 or the air or ink in the neighborhood of the guide hole 49a is unlikely to stick to the table. 帽24具有肋状伸出部分66,它形成在帽24的一个侧壁上,与形成在墨盒体20上的伸出部分34位于相同一侧。 The cap 24 has a rib-like projecting portion 66, which is formed on a sidewall of the cap 24, formed in the protruding portion 34 is located on the same side of the cartridge body 20. 伸出部分66在墨流出的方向上垂直延伸。 Projecting portion 66 extends in a direction perpendicular to the ink flowing out. 如图2B和4所示,伸出部分66和放置在墨盒体20的伸出部分34的内部空间中的遮光板60在垂直方向上(在墨流出的方向上或墨盒3安装到保持器4的方向上)彼此之间隔开预定距离放置,其中伸出部分66处于比遮光板60低的位置。 And FIG. 2B, the portions 66 and disposed in the internal space 20 extending cartridge body portion 34 in the light shielding plate 60 extending in the vertical direction (the direction the ink cartridge 3 or the outflow of the holder 44 is mounted to ) spaced apart a predetermined distance from each other in the direction of placement, wherein the protruding portion 66 is lower than the position of the light blocking plate 60. 换言之,伸出部分66放置在朝向墨盒安装方向的前侧(朝向墨盒3的一个表面,在把墨盒3安装到墨盒保持器4的过程中,该表面首先插入墨盒保持器4 中)与遮光板60分开的位置。 In other words, the protruding portion 66 disposed on the front side to the cartridge mounting direction (toward a surface of the ink cartridge 3, in the process cartridge 3 is mounted to the cartridge holder 4, the surface is first inserted in the cartridge holder 4) and the light shielding plate 60 separate locations. 当墨盒3安装到保持器4上时,伸出部分66放在比传感器14的光发射部分14a和光接收部分14b低的位置。 When the ink cartridge 3 is mounted to the upper holder 4, the protruding portion 66 on the position of the light receiving portion 14a and a lower portion 14b of the light emission ratio sensor 14. 如图7所示,在墨盒3的顶视图中,伸出部分66置于光发射部分14a 和光接收部分14b之间的位置。 As shown in FIG. 7, a top view of the ink cartridge 3, the position of the protruding portion 66 is placed between the light emitting portion 14a and the light receiving portion 14b. 伸出部分66的宽度比伸出部分34的宽度小。 Small-width portion 34 extending width than the projecting portion 66. 伸出部分66的伸出距离比伸出部分34的伸出距离短。 Projecting portion 66 projecting from the projecting portion 34 is projected over a short distance. 只有在把墨盒3安装到保持器4上或者把墨盒3从保持器4上取下时,伸出部分66才从光发射部分14a和光接收部分14b之间穿过以阻碍光发射部分14a发出的光。 Only in the ink cartridge 3 is mounted to the holder 4, or when removing the cartridge 3 from the holder 4, until the extension 66 from the light emitting portion 14a and the light receiving portion 14b passes between the light emitting portion 14a to impede issued Light. 因此传感器M在安装过程中探测到伸出部分66。 M so that the sensor detects the projecting portion 66 during the installation process. 在完成把墨盒3安装到保持器4上的过程的状态下,传感器14探测不到伸出部分66,而是探测到放置在伸出部分34中的遮光板60。 In the completion of the process cartridge 3 is mounted on the holder 4 of the state, the sensor 14 does not detect the extension 66, but is extended to detect the light shielding plate 60 placed in the part 34. 更具体地说,当安装墨盒3或者把墨盒3从保持器4上取下时, 传感器14探测到伸出部分66。 More specifically, when the ink cartridge 3 is mounted or the ink cartridge 3 is removed from the holder 4, the sensor 14 detects the extension 66. 因此控制装置S确定出墨盒3是否安装到保持器4上。 Thus the control apparatus S determines whether the ink cartridge 3 is mounted to the holder 4. 只有在一个方向上安装或取下墨盒3时,传感器14才探测到伸出部分66。 3 only attaching or detaching the ink cartridge in one direction, until the sensor 14 detects the extension 66. 因此,传感器14探测伸出部分66的复杂操作就不必要了。 Thus, the sensor 14 to detect a complicated operation projecting portion 66 is unnecessary. 另外,当墨盒3安装在保持器4上时,还能够避免强度较低的、暴露出来的伸出部分66由于例如与保持器4接触而断裂。 Further, when the ink cartridge 3 is mounted on the holder 4, a lower strength can be avoided, the protruding portion 66 is exposed, for example, because the contact with the holder 4 is broken. 帽24是与墨盒体20分开的部件。 The cap 24 is separated from the cartridge body member 20. 因此墨盒3的帽24的形状可以根据喷墨打印机1的不同规格而改变。 Thus the shape of the cap 24 of the ink cartridge 3 may be changed according to the ink jet printer 1 of different specifications. 例如,如图3所示,在关于伸出部分66宽度方向上的每个端侧,沿垂直方向延伸的肋67形成在墨盒3的帽24上。 For example, as shown in FIG protruding on each side of the end portion 66 in the width direction, a rib 67 extending in the vertical direction is formed on the ink cartridge 24 of the cap 3 3. 由于具有肋67,在保持器4上形成了与肋67配合的槽(未示出)。 Because the ribs 67, the holder 4 is formed in a groove 67 cooperates with a rib (not shown). 帽24上有肋67的墨盒3只安装在和这种帽24相配的喷墨打印机l上。 There ribs 67 on the cap 24 of the ink cartridge 3 is mounted on this cap and mating inkjet printer 24 l. 通过改变肋67的形状、数量和位置,可以实现墨盒体20和帽24之间的多种不同组合。 By changing the shape, number and positions of the ribs 67, you can achieve a variety of different combinations between the cartridge body 20 and the cap 24. 因此,具有特殊规格的墨盒3能够安装在其规格与墨盒3的规格相配的喷墨打印机1上。 Thus, the ink cartridge 3 having particular specifications can be mounted on the ink cartridge specifications match the specifications of the ink jet printer 3 1. 下面描述控制装置8。 The control device 8 will be described below. 控制装置8控制喷墨打印机1的各种操作, 如从打印头2的喷嘴2a喷墨、向打印头2送纸以及在用打印头2完成打印后排纸等。 The control device 8 controls the various operations of the inkjet printer 1, such as from an ink jet printhead nozzle 2a 2, the print head 2 and the completion of the sheet feeding to print the back of the print head 2 in the paper. 控制装置8包括中央处理器(CPU)、只读存储器(R0M)、 随机存储器(RAM)、电可擦除可编程只读存储器(EEPROM)等非易失性存储器、输入/输出接口和总线,其中ROM存储CPU执行的程序和程序中使用的数据,RAM在执行程序时暂时存储数据。 The control device 8 includes a central processing unit (CPU), a read only memory (R0M), a random access memory (RAM), electrically erasable programmable read only memory (EEPROM) nonvolatile memory, an input / output interface and the bus, wherein the ROM stores data and programs executed by the CPU for use, RAM for temporarily storing data when executing a program. 如图l所示,控制装置8根据从个人计算机(PC) 82的外设输入的各种信号控制喷墨打印机1的单元或装置,如打印头2、驱动滑架5的输送机构6 的马达、以及清洗装置7的抽吸泵59等。 As shown in FIG. L, the control device 8 according to various units or devices peripheral input signals from a personal computer (PC) 82 controls the inkjet printer 1, such as print head 2, a carriage driving motor 5 of the conveying mechanism 6 , a suction pump 59 and a cleaning device 7 and the like. 控制装置8起到墨盒探测器80的功能,它根据从传感器14输出的信号探测墨盒3是否安装到保持器4上,还起到剩余墨量计算器81 的功能,即计算墨室31中的剩余墨量。 The control device 8 functions as an ink cartridge detector 80, which detects whether the ink cartridge 3 is mounted to the holder 4, also functions as a remaining ink amount calculator 81, i.e., the ink chamber 31 is calculated based on a signal output from the sensor 14 remaining ink amount. 下面参考图8的流程图描述对墨盒探测器80和剩余墨量计算器81的操作。 The following reference to the flowchart describing the operation of the ink cartridge detector 80 and the residual ink amount calculator 81 8. 在喷墨打印机1打开的状态下,如果传感器14没有探测到设在帽24上的伸出部分66 (S10: NO),那么流程前进到执行剩余墨量计算过程的S14。 In the ink jet printer 1 is opened, if the sensor 14 does not detect the cap 24 is provided on the projecting portion 66 (S10: NO), the flow proceeds to S14 perform the remaining ink amount calculating process. 如果传感器14探测到伸出部分66 (S10: YES),流程前进到Sll,在该步骤判断是否在步骤S10中传感器14探测到伸出部分66之前墨盒3已经安装到保持器4上。 If the sensor 14 detects the projecting portion 66 (S10: YES), the flow advances to the Sll, in step S10, determines whether the step detection sensor 14 to the projecting portion 66 before the cartridge 3 has been attached to the holder 4. 如果在传感器14探测到伸出部分66之前墨盒3已经安装到保持器4上(Sll: YES),那么在S12就判断出墨盒3从保持器4上移走了并且把这样的信息存储在控制装置8中。 If the sensor 14 detects the projecting portion 66 before the cartridge 3 has been attached to the holder 4 (Sll: YES), then in S12 it is judged that the ink cartridge 3 is removed from the holder 4 and such information is stored in the control 8 apparatus. 由于不必计算剩余墨量,流程就返回开始。 Since the remaining amount of ink necessary to calculate the flow returns to start. 如果在传感器14探测到伸出部分66之前墨盒3没有安装到保持器4上(Sll: NO),那么在步骤S13就判断出墨盒3安装到了保持器4上,并且把这样的信息存储在控制装置8中。 If the detection sensor 14 to the projected before section 66 ink cartridge 3 is not mounted to the holder 4 (Sll: NO), then in step S13 it is judged that the ink cartridge 3 is mounted to the holder 4 and such information is stored in the control 8 apparatus. 然后流程前进到S14 去执行剩余墨量计算过程。 Then the flow proceeds to S14 to perform the remaining ink amount calculating process. 在剩余墨量计算过程S14中,当墨室31中的剩余墨量充足并且传感器14探测到遮光机构23的遮光板60时,根据墨盒3的最大墨容量和把墨盒3安装到保持器4上后一共喷出的墨滴数目来估计墨室31中的剩余墨量。 In the remaining ink amount calculating process S14, when a sufficient amount of ink remaining in the ink chamber 31 and the sensor 14 detects the light shielding mechanism shielding plate 6023 is attached to the holder 4 based on the maximum ink capacity of the ink cartridge 3 and the cartridge 3 after the total number of ink droplets discharged to estimate the remaining amount of ink in the ink chamber 31. 当墨室31中的剩余墨量较少并且传感器14没有探测到遮光机构23的遮光板60时,就根据传感器14探测不到遮光板60那一刻的剩余墨量和从传感器14探测不到遮光板60起喷出的墨滴总数来更精确地计算墨室31中的剩余墨量。 When the small remaining amount of ink in the ink chamber 31 and the sensor 14 does not detect the light shielding mechanism 23 when the light shielding plate 60, according to the remaining ink amount sensor 14 does not detect the light shielding plate 60 and from the moment the sensor 14 can not detect the light shielding remaining amount of ink 31 in the plate 60 from the total number of ink droplets to more accurately calculate the ejected ink chamber. 把在步骤S14中计算出来的和剩余墨量相关的信息在步骤S15送到PC82并且流程返回START。 Calculated in the step S14 and the remaining amount of ink-related information in step S15 and the flow returns to the PC82 START. 关于墨盒3是否安装到保持器4上和喷出墨滴总数的信息存储在如EEPROM等非易失性存储器中,以便在关闭喷墨打印机l后保持这些信息。 Whether the ink cartridge 3 is mounted on the holder 4 and the total number of ink droplets ejected information stored in a nonvolatile memory such as an EEPROM and the like so as to maintain the information after the inkjet printer closed l. 在上述的实施例中,使用一个传感器14能够探测到墨盒3是否安装到保持器4上和墨室31中剩余墨量这些状态。 In the above embodiment, using a sensor 14 capable of detecting the remaining amount of ink the ink cartridge 3 is installed in the holder 4 and the ink chamber 31 on these states. 传感器14探测遮光板60随墨室31中剩余墨量而移动的位置。 The remaining amount of ink 31 moves the position sensor 14 to detect the light shielding plate 60 with the ink chamber. 根据传感器14不能探测到遮光板60那一刻所探测到的剩余墨量能够精确计算出墨室31中的剩余墨量。 The remaining ink amount sensor 14 can not detect the light shielding plate 60 that moment can be accurately detected to calculate the remaining amount of ink in the ink chamber 31. 伸出部分34只形成在墨盒3的一个侧壁上,这使得墨盒3不对称。 Protruding portion 34 is formed on a sidewall of the ink cartridge 3, making the ink cartridge 3 asymmetrical. 因此就能够避免墨盒3不正确地安装到保持器4上。 Thus it is possible to prevent incorrect installation of the ink cartridge 3 to the holder 4. 当把墨盒3安装到保持器4上时,肋55起到引导件的作用,用来引导保持器4的相对侧壁。 When the ink cartridge 3 is mounted to the holder 4, the ribs 55 function as guides for guiding an opposing side wall 4 of the holder. 因此,能够正确地把墨盒3安装到保持器4 上。 Accordingly, the cartridge 3 can be accurately attached to the holder 4. 在伸出部分34和光发射部分14a/光接收部分14b之间保持了预定的距离,这样就能够很容易地把墨盒3安装到保持器4上或从保持器4 上取下。 In the protruding portion 34 and the light emitting portion 14a / light receiving holding a predetermined distance between the part 14b, so it can easily be attached to the cartridge holder 3 or 4 is removed from the holder 4. 伸出部分66的宽度比伸出部分34的宽度小。 Small-width portion 34 extending width than the projecting portion 66. 伸出部分66的伸出距离比伸出部分34的伸出距离短。 Projecting portion 66 projecting from the projecting portion 34 is projected over a short distance. 因此能够很容易地把墨盒3安装到保持器4上或从保持器4上取下。 It can be easily mounted to the cartridge holder 3 or 4 is removed from the holder 4. 墨盒3设有在把供墨管12插入墨盒3时打开的供墨阀21,所以就能够避免在把墨盒3安装到保持器4上时墨从供墨管12中泄漏出来。 In the ink cartridge 3 is provided with the ink supply opening when the ink supply tube 12 inserted into ink cartridge 3 the valve 21, it can be avoided mounted to the holder 4 when the ink leaking from the ink supply tube 12 in the cartridge 3. 在上述的实施例中,当连接件62随着墨室31中剩余墨量变化而移动时,遮光板60随之移动。 In the above embodiment, when the connection member 62 moves with the remaining amount of ink 31 in the ink chamber changes, the light shielding plate 60 moves with it. 但是,通过把遮光板60直接连接到漂浮在墨上的浮子上也可以移动遮光板60。 However, by the light shielding plate 60 is directly connected to the float floating on ink shading plate 60 may also be moved. 伸出部分34形成在墨盒3的一个侧壁上。 Projecting portion 34 is formed on a sidewall of the ink cartridge 3. 但是,可以在墨盒3的相对侧壁上形成与伸出部分34具有基本相同形状的另一个伸出部分。 However, the other may be formed with the projecting portion 34 has substantially the same shape as projecting portions on opposite side walls of the ink cartridge 3. 在这种情况下,优选不论墨盒3是否朝向相反方向,墨盒3都能正确地安装到保持器4上。 In this case, it is preferable regardless of whether the ink cartridge 3 in the reverse direction, the ink cartridge 3 can be properly attached to the holder 4. 可以取消起到引导件功能的肋55。 It can act as a guide member function cancellation rib 55. 当墨盒3安装到保持器4上时,在伸出部分34和光发射部分14a/ 光接收部分14b之间保持了预定距离。 When the ink cartridge 3 is mounted to the holder 4, the projecting portion 34 and between the light emitting portion 14a / light receiving portion 14b is maintained for a predetermined distance. 但是,可以放置伸出部分34使之与光发射部分14a和光接收部分14b紧密接触。 However, the protruding portion 34 may be placed so that the light emitting portion 14a and the light receiving section into close contact 14b. 伸出部分66的宽度比伸出部分34的宽度小。 Small-width portion 34 extending width than the projecting portion 66. 伸出部分66的伸出距离比伸出部分34的伸出距离短。 Projecting portion 66 projecting from the projecting portion 34 is projected over a short distance. 只要伸出部分66能够从光发射部分14a和光接收部分14b之间穿过,可以改变伸出部分66的形状。 As long as the extension 66 can be emitted through the light between the portions 14a and 14b from the light receiving portion, may change shape portion 66 protrudes. 例如,伸出部分66可以和伸出部分34具有相同的宽度或者具有比伸出部分34宽的宽度。 For example, the projecting portion 66 and the extended portion 34 may have the same width or wider than the width 34 having the protruding portion. 伸出部分66可以和伸出部分34具有相同的伸出距离或者具有比伸出部分34的伸出距离长的伸出距离。 And a protruding portion 66 protruding portion 34 may have the same protruding distance or a distance longer than a projecting distance of projecting portion 34 projecting. 在该实施例中,沿着形成在墨盒体20上的伸出部分34的延伸方向,肋状伸出部分66形成在帽24的一个侧壁上。 In this embodiment, are formed along the extending direction of the projecting portion 34 on the cartridge body 20, the rib-like projecting portion 66 is formed on one side wall 24 of the cap. 但是,喷墨打印机l 可以使用不同的方式来探测墨盒3是否安装到保持器4上,而不必局限于使用伸出部分66。 However, inkjet printers l may be used in different ways to detect whether the ink cartridge 3 is mounted to the holder 4, but not necessarily limited to the use of the extension 66. 例如在墨盒体20或帽24上,沿着伸出部分34 的延伸方向可以提供薄板形成的遮光件,这样当把墨盒3安装到保持器4上时,传感器14在探测到伸出部分34之前探测到该遮光件,在把墨盒3从保持器4上取下时传感器14也探测到该遮光件。 For example, in the cartridge body 20 or the cap 24, along the extending direction of the projecting portion 34 may be provided a light-shielding sheet member is formed, so that when the ink cartridge 3 is installed in the holder 4, the sensor 14 detects the projecting portion 34 before the light shielding member is detected, when the cartridge 3 is removed from the holder 4 to the sensor 14 can detect the light blocking member. 遮光件的材料可以是任何不透光的材料。 The light blocking member material may be any opaque material. 可以用通常的方式固定遮光件,如热焊接或粘结等。 The light shielding member may be fixed, such as thermal welding or the like bonded in the usual manner. 在阀室32中设有供墨阔21。 Width is provided an ink supply chamber 21 in the valve 32.但是,可以不把供墨阀21放在阀室32中,而是用弹性件或密封件来密封阀室32。在这种情况下,当墨盒3安装到保持器4上时,供墨管12可以插入弹性件或密封件。下面描述第二个实施例。注意这里用类似的附图标记表示类似的元件。第一个实施例结合进行描述的墨盒3a-3d具有基本相同的结构和容量。第二个实施例将结合彩色墨的墨盒3a-3c与具有比墨盒3a-3c大的容量的黑色墨的墨盒3d'进行描述。由于与青色、黄色或洋红色墨相比,要更频繁地使用黑色墨,所以可能要较大的墨盒3d'。如果不经常使用喷墨打印机1而大墨盒3d'又一直安装在保持器4上,那么墨盒3d' 中的大量墨就会长时间地处于不使用状态,这会导致墨的品质下降。因此根据第二个实施例的喷墨打印机1构造成使得图1所示的保持器4d能够有选择地在其上安装与墨盒3a-3c具有相同容量的墨盒3d或大墨盒3d'(图9A和9B)。如图9A和9B所示,大墨盒3d'包括墨盒体70和覆盖墨盒体70 下部的帽71。伸出部分76形成在帽71上。伸出部分76具有大致为叉形的形状,具有在垂直方向上对齐的探测部分76a、 76b。探测部分76a、 76b都不具有透光性。当把容量较小的墨盒3d安装到保持器4上或从保持器4上取下时,伸出部分66只阻挡光发射部分14a发出的光一次。当把大墨盒3d'安装到保持器4上或从保持器4上取下时,伸出部分76 的探测部分76a、 76b两次阻挡光发射部分14a发出的光。这样控制装置8根据光发射部分14a发出的光被阻挡的次数(探测到伸出部分66、 76的次数)就能够探测保持器4上安装了墨盒3d还是3d'。下面参考图10的流程图描述当可拆卸地把墨盒3d、 3d'安装到保持器4d上时墨盒探测器80和剩余墨量计算器81所执行的操作。在喷墨打印机1打开的状态下,如果传感器14没有探测到设在帽24上的伸出部分66、 76 (S110: NO),那么流程前进到执行剩余墨量计算过程的S116。如果传感器14探测到伸出部分66、 76 (S〗】0: YES),流程前进到Slll,在该步骤判断是否在步骤S110中传感器14探测到伸出部分66、 76之前墨盒3d、 3d'已经安装到保持器4上。如果在传感器14探测到伸出部分66、 76之前墨盒3d、 3d'已经安装到保持器4上(Slll: YES),那么在S112就判断出墨盒3d、 3d'从保持器4上移走了,并且把这样的信息存储在控制装置8中。由于不必计算剩余墨量,流程就返回开始。如果在传感器M探测到伸出部分66、 76之前墨盒3d、 3d'没有安装到保持器4上(Slll: NO),并且探测到伸出部分66—次(S113: YES),那么在S114就判断出小墨盒3d安装到了保持器4d上,并且把这样的信息存储在控制装置8中。然后流程前进到SH6去执行剩余墨量计算过程。如果在传感器14探测到伸出部分66、 76之前墨盒3d、 3d'没有安装到保持器4d上(Slll: NO),并且探测到伸出部分76两次,即探测到探测部分76a、 76b (SIB: NO),那么在S115就判断出大墨盒3d'安装到了保持器4上,并且把这样的信息存储在控制装置S中。然后流程前进到S116去执行剩余墨量计算过程。在剩余墨量计算过程S116中,当墨室31中的剩余墨量充足并且传感器14探测到遮光机构23的遮光板60时,根据墨盒3d、 3d'的最大墨容量(墨盒3d和3d'的最大墨容量不同)和把墨盒3d、 3d'安装到保持器4上后一共喷出的墨滴数目来估计墨室31中的剩余墨量。当墨室31中的剩余墨量较少并且传感器14没有探测到遮光机构23的遮光板60时,就根据传感器14探测不到遮光板60那一刻的剩余墨量和从传感器14探测不到遮光板60起喷出的墨滴总数来更精确地计算墨室31中的剩余墨量。把在步骤S116中计算出来的和剩余墨量相关的信息在步骤S117送到PC82并且流程返回开始。关于墨盒3d、 3d'是否安装到保持器4d上、如果已经安装了那么是墨盒3d还是3d'安装到保持器4d上、以及喷出墨滴数的信息存储在如EEPROM等非易失性存储器中,以便在关闭喷墨打印机1后保持这些信息。根据第二个实施例的墨盒3和喷墨打印机1将达到下述效果。形成在帽24上的不透光伸出部分66、 76和放置在伸出部分34内部空间中的遮光板60沿着墨盒3的安装方向设置。伸出部分66、 76 所处的位置比遮光板60低(墨盒3安装方向的前恻,即朝向墨盒3的一个表面,在把墨盒3安装到墨盒保持器4的过程中,该表面首先插入墨盒保持器4中)。因此,只有在墨盒3安装到保持器4上时或者从保持器4上移走时,探测剩余墨量的传感器14才探测到伸出部分66、 76,并且墨盒探测器80能够确定墨盒3是否安装到保持器4上、以及如果已经安装了那么保持器4上是安装了墨盒3d还是3d'。因此,作为探测墨盒3是否安装到保持器4上以及如果已经安装了那么是安装了墨盒3d还是3d'的探测器不必与传感器14分别设置。这样就避免增加生产成本。只有在一个方向上把墨盒3安装到保持器4上时或者从保持器4上移走时传感器14才探测到伸出部分66、 76。因此,传感器14探测伸出部分66、 76的复杂操作就不必要了。另外,当墨盒3安装在保持器4上时,还能够避免强度较低的、暴露出来的伸出部分66、 76例如由于与保持器4接触而断裂。含有黑色墨的小墨盒3d和大墨盒3d'分别具有伸出部分66、 76, 它们的形状彼此不同。因此利用伸出部分66、 76墨盒探测器80能够确定墨盒3d、 3d'是否安装到保持器4d上和如果已经安装了是安装了墨盒3d还是3d'。根据墨盒探测器80探测出来的安装到保持器4d上的墨盒3d、 3d'的类型,剩余墨量计算器81精确地计算墨盒3中的剩余墨量。下面描述根据第二个实施例的改进。 (1) 为了在把墨盒3安装到保持器4上或者从保持器4上移走时避免损坏伸出部分66、 76,墨盒3可以具有一个盖件来覆盖至少一部分伸出部分66、 76。如图ll所示,根据第二个实施例的一个改进的墨盒90包括墨盒体91和帽92,帽92上形成有伸出部分93。在墨盒体91上设有沿垂直方向延伸的大致为长方形柱状的盖94。盖94覆盖住伸出部分93的上部或者伸出部分93的上部插入盖94。因此在墨盒90中,盖94保护伸出部分93。所以,即使在把墨盒90安装到保持器4上时伸出部分93与保持器4接触,也不大可能损坏伸出部分93。可以用可透光盖件把伸出部分93完全覆盖起来。这样就能够进一步避免损坏伸出部分93。 (2) 可以整体形成墨盒体20、 70、 91和帽24、 71、 92。因此就能够减少墨盒3、卯使用的部件数目。另外,还能够去掉把帽24、 71、 92连接到墨盒体20、 70、 91上这一装配过程,从而能够避免增加生产成本。 (3) 探测墨盒3、 90中剩余墨量的传感器不限于输出信号的光学传感器14,该信号与光发射部分14a发出的直射光是否到达光接收部分14b相对应,并且光接收部分14b与光发射部分14a用几乎笔直的光路相连。例如,可以釆用这样一种输出信号的光学传感器,该信号与光接收部分是否接收到光发射部分发出的并且在被探测件的表面上反射的光相对应。在这种情况下,几乎笔直从光发射部分发出的光的光路可以被具有预定反射系数的部件暂时阻碍。与反射系数相关的、 从部件上反射出的间接光入射到光接收部分。例如,用来探测墨盒3、 90是否安装到保持器4上的伸出部分66、 76、 93可以用具有预定反射系数的不透光材料形成。可以布置光学传感器使之与墨盒3、 90的安装/拆卸途径相关连,光学传感器根据是否接收到反射光来输出信号,从而使得在可拆卸地把墨盒3、 90安装到保持器4上时,光接收部分以预定的光强接收到光发射部分发出并且在伸出部分66、 76、 93上反射的间接光。这样就能够达到类似于第二个实施例的效果。另外, 一部分帽24、 71、 92可以具有预定的反射系数。在这种情况下,光学传感器的光发射部分和光接收部分可以不彼此相对放置,并且探测部分可以不必具有阻碍光路的结构。与具有预定反射系数的伸出部分66、 76、 93类似,遮光板60的结构也可以具有预定的反射系数。另外,可以利用墨和墨盒体20、 70、 91的可透光壁的反射系数之间的差别来反射间接光,而不使用遮光板60。更具体地说,在墨接触墨盒体20、 70、 91的壁的情况下,光接收部分可以接收到从墨和墨盒体20、 70、 91的壁之间的界面反射出的间接光。在墨用光的情况下,光穿过墨盒体20、 70、 91的壁,所以光接收部分不能接收到光。因此,可以把探测墨盒3、 90中剩余墨量的探测器和探测墨盒3、 90是否安装到喷墨打印机1上的探测器组合起来使之具有相对简单的结构。也可以使用接触型传感器来取代非接触型光学传感器14,(4)
