Definitions

  • the present invention relates to an ink container according to the preamble of claim 1.
  • the invention relates further to an ink jet recording apparatus for using such ink container.
  • an ink jet recording apparatus is excellent in that it can perform a high speed recording since a noise during the recording is very small and it can be easily constructed as a high density multiple discharge port type ink jet printer. Further, it has been interested in that the ink jet printer has good color reproducibility for a color image.
  • an ink jet recording system ink jet recording apparatus
  • ink jet recording apparatus is so constructed that ink droplets are caused to be discharged and fly from a discharge port of a recording head, and recording is carried out with their sticking on a recording sheet. So, in the ink jet recording apparatus, it is needed to supply surely ink to the ink jet recording head. In the past, various contrivances have been made for this purpose.
  • a method is known of obtaining a sure connection of the flow path with the connecting portion of the ink cartridge side by causing the member of the device side to have a degree of freedom, as shown in Japanese Patent Laid-Open Application No. 60-137658.
  • the above-mentioned cartridge type ink tank arrangement is weak in vibration and shock because it holds ink with a soft bag, and if the manners in which the bags collapse are nonuniform, then the pressure with which ink is let to flow would be often caused to change. Accordingly, this arrangement is not suitable to a large volume ink tank, and in fact it is realized as a relatively small ink tank.
  • an ink tank shown in Japanese Laid-Open Patent Application No. 56-13456 which has a construction which is strong in vibration and shock and permits it to be voluminous by holding ink between the outside of the bag which communicates to the air and a frame.
  • the problem relating to the change of the pressure with which ink flows out which is due to a difference between the manners in which the bags collapse (or swell) is not solved entirely, and it is needed to cause ink to flow out compulsively with an ink pump, store ink temporarily in a sub-tank which is provided with special means communicating to the air and then supply it to the head, so as thereby to carry out stabilized ink supplying.
  • This container comprises a plurality of flexible bags formed on a single strip which can be folded in order to place it into a container body, wherein the joint member comprises a single supply inlet for each of the individual bags serving as ink tanks.
  • the object of the present invention is to provide an ink container as well as an ink jet recording apparatus by means of which ink can be suitably supplied.
  • Fig. 1 is a cross-sectional side view showing a facsimile apparatus to which an embodiment of the present invention is applied.
  • Fig. 2 is a cross-sectional side view showing another state of the apparatus shown in Fig. 1.
  • Fig. 3 is a typical view schematically showing a structural example of the ink supply passage of an ink jet recording apparatus according to the present invention.
  • Fig. 4 is a perspective view showing a structural example of ink supplying means of an ink jet recording apparatus according to the present invention.
  • Fig. 5 is an exploded perspective view showing an structural example of an ink cartridge installed in an ink jet recording apparatus according to the present invention.
  • Figs. 6A and 6B are a partially cutaway sectional side view showing the structural example of the ink cartridge and a partially enlarged view thereof to show the state of mating with the ink supplying means.
  • Fig. 7 is a partially cutaway sectional front view of the structural example of the ink cartridge.
  • Fig. 8 is a schematic top view showing the structural example of the ink cartridge.
  • the present invention which will be explained hereinafter was made on the bases thereof, and relates to a ink jet recording apparatus comprising ink supplying means for permitting the supply of ink to an ink jet recording head and an ink cartridge detachably mounted on said ink supplying means and providing with an ink tank accommodating therewithin ink to be supplied, said ink supplying means having a stationary ink supplying side joint portion adapted to be connected to said ink tank, said ink tank within said cartridge having an ink tank side joint portion connected to said ink supplying side joint portion and supplying ink, and said ink tank having a freedom of motion in the rotation direction with respect to the central axis of its joint portion to permit said ink tank to displace when said ink supply side joint portion and said ink tank side joint portion are connected to each other.
  • the ink container is retained movably within the frame enclosing it, specially in the direction of its rotation with respect to the central axis of the connecting portion (joint portion), and thus, a freedom in connection of the connecting portion of the device side and the corresponding connecting portion of the ink cartridge side is easily secured, and even though there are provided a plurality of flow paths to be connected, the positioning of the device side joint portions to the ink container side joint portion is made easily and surely.
  • the joint portion of the device side (ink supplying means side) is made to be stationary, the distribution of the ink tube form here to the recording head can be made to be compact and simple.
  • this invention relates to in an ink supplying device having a plurality of ink paths adapted to be connected to an ink jet recording head, joint means comprising a first ink coupling portion connected to said ink jet recording head through an ink pump, a second ink coupling portion different from said first ink coupling portion and connected to said ink jet recording head, and a connecting portion for performing communication to the air, whereby an ink tank with said portions is detachably mounted to said ink jet recording head.
  • the ink supply can be carried out very suitably without the use of not only the ink bag but also the sub-tank since the ink supporting port is jointed directly to the member constituting the ink supplying path. Also, since the port of the ink tank opening to the air is joined to the connecting portion for performing the communication to the air so that the ink tank can be caused to communicate to the air, it is possible to provide the ink tank which does not request that it be in the form of the above-mentioned bag arrangement, which is strong in vibration and shock and which is voluminous.
  • Fig. 1 is a central sectional view showing an embodiment of facsimile apparatus characteristically representing the present invention.
  • the facsimile apparatus of the present embodiment roughly comprises original conveying system A, optical system B, power source unit C, electric circuit board D, recording sheet conveying system E, decurling system F, ink supply system G, and recovery system H.

  • an ink cartridge cam prises recording head 38, ink pump 76, ink tank 86, wast ink absorber 96, and air duct 87 which is called breezer.
  • ink pump 76 is actuated in a state where cap 41 is closely contacted with the recording head (a state shown in Fig. 2 where projection in cap 41 is in contact with nozzle section of recording head 38) to circulate ink from ink cartridge 86 in the direction indicated by arrow E, so that the inside of the tubes including the inside of the recording head is filled with ink. At this time, some ink is flown out to cap 41, but it is returned to ink cartridge 86 through waste ink tube 45 and collected to built-in ink absorber 96.
  • recording head 38 is ready to discharge ink.
  • the ink pump used in the present embodiment is a pump which does not close the flow passage when the pump is at rest. Therefore, the ink supply at the time of discharging is carried out from both front and rear head ink couplers 38d and 38e.
  • Breezer 87 functions as an air duct for this purpose.
  • check valves capable of being opened by an extremely small difference in pressures are respectively arranged in both directions. Therefore, the valves function if a slight pressure, either negative or positive, is generated in the tank, and operate as air holes substantially.
  • the valves are also arranged to control dust intrusion and evaporation.
  • a reference numeral 92 designates a no-ink detector for detecting no-ink condition in tank 94.
  • the detection is carried out in a manner given below.
  • sensor 88 is arranged for detecting a light interruption.
  • the recovery operation is an action to remove bubbles and cloggings which bender the normal discharging, and is performed in accordance with the recovery sequence, which will be described later, controlled by the recovery system.
  • the recovery operation is exactly the same as the initial ink supply operation.
  • ink pump 76 is actuated while cap 41 is in contact with recording head 38 (the current state is illustrated in Fig. 2) to circulate ink in the direction indicated by arrow A, so that bubbles are collected into the ink tank to release them to the outside through the breezer.
  • the contacting condition between projection in cap 41 and the nozzle of the recording head is released to drive the pump for the removal of any clogging in the nozzle.
  • pressurized ink is flown into float chamber 90.
  • float 89 is raised to closely contact with upper face of float chamber 90 to cover the passage to breezer 87. Therefor, no ink is flown into breezer 87.
  • Fig. 4 is a perspective view showing the construction of supply and recovery systems, in which the structure of the present embodiment is actually employed.
  • a reference numeral 73 designates the base of this unit which also functions as a base for installing ink cartridge 86, which will be described later.
  • a reference numeral 74 designates a member called joint plate which is formed by fixing each of various passage couplers.
  • cartridge guide 78 for positioning ink cartridge 86, cartridge joints 79a, 79b, and 79c for connecting tubes to release air, waste ink joint 81 for guiding waste ink produced at the time of recording to waste ink absorber 96 built in ink cartridge 86 through waste ink tank, air joint 80 for connecting the breezer for releasing air with air tube 83, first and second supply tube joints 84 and 85 for connecting first and second ink supply tubes 71 and 72 with ink pump 76 which is driven by pump motor 77.
  • ink joint 79 connected to ink tank 94 accommodated in ink cartridge 79a provides three functional sections intensively, first ink supply section 79a, second ink supply section 79b, and air passage connecting section 79c, and with its structure, enables first ink supply inlet 95a, second ink supply inlet 75b and air inlet 95c to be coupled altogether, which are operationally related to the function of ink tank 94.
  • the air passage section leading to the ink tank is formed by joints, thereby making it possible to construct the ink tank with hard resin material to reserve a large quantity of ink without employing ink bags.
  • an ink circulation passage is formed to perform ink supply from both of the ink supply regions at the time of recording and to circulate ink from the ink tank through the passage with the pump inbetween, and to circulate ink from the recording head to the ink tank again at the time of initial ink filling and recovery operation.
  • the passage is formed by directly joining the tank and the supply passage, and further the air passage as described earlier, it becomes possible to eliminate, in spite of the ink tank being made of hard plastic resin, such function as a sub-tank which has conventionally been indespensable for a stable ink supply.
  • these members are separately fixed to joint board 74, but the structure may also be such that these members are integrally formed with the joint board.
  • flow passage board 75 is coupled with flow passage gloove 75a which functions as ink flow passage. In this portion, most of the ink flow passage pipings and connections are installed.
  • joint section 79 which is annexed to joint board 74 connected to ink tank 94, it becomes possible to provide a structure thereby eliminating the operation related to ink passage 75a in that particular portion.
  • a part of ink passage from ink tank 94 to the recording head can be formed only by coupling to the reverse side of joint board 79 the flow passage plate 75 which constitutes a flow passage.
  • ink tank 94 built in ink cartridge 86 is flexibly accommodated in housings 93a and 93b which constitute the cartridge 86.

  • Fig. 6B is a partially cutaway cross-sectional view showing joint section 95 connected to the cartridge joint of the ink supply system.
  • metal ball 99 is provided in joint section 95 to press it against joint port 95a by the compression of spring 98.
  • metal ball 99 is closely in contact with shealing rubber 101 to close the port 95a of the joint section.
  • ink tank has sloped surfaces or slants 94a, 94b at its bottom.
  • slant 94a for gathering ink flow into joint section 95 from behind

  • ink tank 94 with spaces 97 (in this embodiment, for example about 1.0 mm) and spaces 97a (for example, about 1.0 - 2.0 mm) provided for both ends of ink tank 94 and by waste ink absorber 96 which is soft like felt.
  • a projection 93d supports a front bottom of the ink tank 94.
  • the ports 95a, 95b and 95c of the ink tank are provided about 0.5 mm lower with respect to the body joints 79a, 79b and 79c so that the ink tank 94 is connected to the body joints in a state which it floats about 0.5 mm to the body joints. Furthermore, in order to prevent any abnormal sound generated by the movement of ink tank 94 by vibrating impact, etc. or breakage of housing as well as to effectively utilize space, the central part of waste ink absorber 96 is removed as shown in Fig. 5 to allow the lowest bottom ink tank 94 to be fitted into the removed part, so that the ink tank is held by the remaining portion of circumference.
  • the ink container relating to three flow paths was explained as a sample, but it is possible to remove any extra backlash by limiting the degree of freedom in a certain direction depending on the construction or number of the flow paths.
  • the engagement of the container with the device is made only with the cylindrical portion at the periphery of the joint portions, but if such cylindrical portion for the engagement is changed in number or shape (for example to a polygonal or elliptic cylinder shape), then it is possible to reduce an extra degree of freedom after the mounting, and improve the stability of the seal for the connecting portion.
  • the above-mentioned embodiment is so constructed that three connections relating to the communicating port to the air, the supplying side to the recording head at the time of the ink circulation and the returning side, respectively are made, but in order to achieve more effectively the removal of the babbles due to the ink circulation by decreasing the flow path resistance, correspondingly to the structure of the recording head, more supplying tubes may be used. At that time, it is possible to divide the supplying side and the returning side to plural ones, respectively, by applying thereto the above-mentioned embodiment.
  • the structure in which the waste ink absorbing body is positioned on the bottom of the ink tank was explained.

  • the ink jet recording apparatus which has the reliable joint portions from which any ink leakage due to vibration or shock does not occurred.
  • three connections for the paths for supplying ink at the time of the circulation, the returning path and the communicating port to the air are used detachably between the ink tank side and the joint sides, and thus, it is possible to provide the ink supplying device which is voluminous, and strong in vibration and shock and which has no use for the sub-tank.
  • the ink jet recording apparatus having the ink supplying device which is low-priced, compact and moreover highly reliable. Also, in the above-mentioned embodiments, by not only holding the ink tank at its periphery with a soft member and but also using such soft member as the waste ink absorbing body, it is possible to achieve an ink cartridge which is strong in vibration and shock, which can use effectively the space and which is compact and low-priced. In this connection, it is also possible to provide the ink jet recording apparatus which is miniaturized and has its decreased running cost and improved reliability.
