1 TITLE OF THE INVENTION

2203386 An Ink Tank and A Liquid Ejection Recording Apparatus Provided with The Ink Tank BACKGROUND OF THE INVENTION

Field of the Invention

This invention relates to an ink tank for supply of recording liquid carried in a liquid injection recording apparatus, and to a liquid injection recording apparatus provided with a carriage carrying a recording head thereon and movable to scan and said ink tank. Related Background Art

Many of liquid injection recording apparatus of this type are of a form in which, as shown in U.S. Patent No. 4,447,820, a removable mountable cartridge type tank 1 for recording liquid is mounted in the body of the apparatus, and as such tank (the cartridge type: hereinafter simply referred to the ink cartridge), use has generally been made of a flexible bag havingrecording liquid hermetically sealed therein and contained in a housing having a vent po rt. That is, the ink cartridge of the construction as described above has often been used to achieve the purpose of preventing evaporation of the hermetically sealed recording liquid and the purpose of keeping the recording liquid under the same degree of pressure as the atmospheric pressure for smooth supply of the recording liquid.

2 - 1 However, in the thus constructed ink cartridge, the construction of the bag is complicated and costly and moreover, the bag which is flexible is unexpectedly weak to vibration and shock, and this has sometimes adversely affected the containment and supply of the recording liquid. So, there has been proposed an ink cartridge of simple construction and low cost which disuses a flexible sealed bag and contains recording liquid directly in a housing. In order that supply of recording liquid may be accomplished smoothly, such an ink cartridge has been provided with a vent port or provided with atmosphere-communicating means for keeping the recording liquid at the atmospheric pressure as by inserting into the ink cartridge a hollow needle connected to a tube communicating with the atmosphere.

Further, in such an ink cartridge, in order to prevent the recording liquid from evaporating through the atmosphere-communicating means, it has been proposed to provide as the atmosphere-communicating means an electromagnetic valve adapted to be opened when the main switch for recording is closed, or a valve adapted to be opened and closed by a pressure difference. It has also been proposed to minimize the size of the vent port to thereby prevent evaporation of the recording liquid.

However, using an electromagnetic valve or the like to open and close the communication between the atmosphere and the recording liquid requires a large-scale 1 1 construction and a high cost, and the provision of a valve adapted to be opened and closed by a pressure difference has led to the disadvantage that the openingclosing of the valve is affected by a change in the ambient temperature or the like. Also. the minimization of the size of the vent port has led to the disadvantage that the vent port is liable to be readily clogged by dust such as paper powder and becomes unable to fully perform its function as the atmosphere-communicating means. Further, such a cartridge has also suffered from the disadvantage that the recording liquid is generally liable to spill through the atmospherecommunicating means and thereby contaminate the surroundings.

SUMMARY OF THE INVENTION

It is an abject of the present invention to provide an inexpensive ink cartridge which is of very simple structure and which can open and close the communication path with the atmosphere and can directly contain recording liquid and to provide a liquid injection recording apparatus in which during the pause of recording. the vent port of said cartridge is closed to thereby prevent evaporation of the recording liquid and no great cost is required for the opening-closing of the vent port To achieve such object. the present invention is characterized in that in a liquid injection recording apparatus wherein a carriage is moved along a platen 4 from the home position as a non-recording area and recording liquid is injected from a recording head carried on the carriage to thereby accomplish recording and supply of the recording liquid is effected by an ink cartridge, opening-closing means for opening and closing a vent path communicating with the a tmosphere and the recording liquid containing portion of the ink cartridge is provided in the vent path and atmospherecommunicating means is provided for operating said opening-closing means when the carriage is directed to the home position, thereby closing the vent path.

In the liquid injection recording apparatus according to the present invention, when the carriage is returned to the home position as during the pause of recording, a magnetic member as the opening-closing means provided in association with the vent path of the ink cartridge is subjected to attraction or repulsion by the magnetic force of a magnet as magnetic force imparting means and is thereby moved to close the vent path, whereby the recording liquid can be prevented from evaporating. Also, when the carriage is moved away from the home position as during recording. the influence of the magnet becomes null and the magnetic member is moved to its original position as by its gravity to open the vent path and the recording liquid containing portion of the ink cartridge communicates with the atmosphere, whereby smooth supply of the recording liquid can be accomplished.

Y Or, in the liquid injection recording apparatus according to the present invention, when the carriage is moved to the recording area, the vent path of the ink cartridge can be opened by the magnetic force of the magnet, and when the carriage is moved away from the recording area. the influence of the magnet becomes null, whereby the vent path can be closed.

DESdRIPTION OF THE PREFERRED EMBODIMENTS Some enbodiments of the present invention will hereinafter be described in detail and specifically with reference to the drawings.

Figures 1A and IB show an example of the construction of an ink cartridge suitable for carrying out the present invention. The ink cartridge 1, as shown in Figure 1A, has a supply path 3 branching off from a recording liquid containing portion 2. and an air path 4 formed above the recording liquid containing portion 2. A supply port 3A is formed in the upper portion of the supply path 3, and an air port 4A is formed in a cartridge shell 1A in the air path 4. The reference numeral 5 designates a cover member mounted in such a manner as to cover the outer sides of the supply port 3A and air port 4A, and the reference numeral 6 denotes a sealing elastic member as a seal member of silicone rubber, butyl rubber or like material held by the cover member 5 and covering the outer sides of the supply port 3A and air port 4A.

The cover member 5 has insertion ports 7A and 7B at locations therein opposed to the supply port 3A and the air port 4A. respectively, and during the use of the ink cartridge 1, a needle tube 8A for directing recording liquid to a recording head, not shown, and a needle tube 6B communicating with the atmosphere are inserted into the insertion ports 7A and 7B, respectively, and are further caused to pass through the elastic member 6 into the supply port 3A and the air port 4A, respectively, whereby the interior of the ink cartridge becomes equal to the atmospheric pressure and thus, a recording liquid supply state can be brough about.

In Figure 1A. the recording liquid does not reach the upper portion of the supply path 3. but since the recording liquid was made continuous to the recording head as by sucking the recording liquid by such means such as a pump. not shown, through the needle tube 8A, the recording liquid could be continuously supplied as it was consumed.

Further. in Figure 1A. the reference numeral 9 designates a communication port communicating between the air path 4 and the recording liquid containing portion 2. the reference numeral 10 denotes a ball member as opening-closing means, and the reference numeral 11 t 8 - designates a ball member receiver provided below the ball 10. The ball member 10, as shown in Figures 2A and 2B, has a ball 10A of a magnetic material such as iron, cobalt or nickel at the center thereof and a concentric covering member lOB of ahigh molecular material such as rubber or synthetic resin. specifically, polyethylene. polypropylene or polyacetal surrounding the ball 10A, and by the covering member 10B, the hermetically-sealing capability was enhanced and further, rusting of the ball 10A of a magnetic material could be prevented.

Thus, the ball member 10 is held between the communication port 9 and the ball member receiver 11 with a play around it, and when. as shown in Figure 2A, a magnet piece 12 which is magnetic force inparting means becomes proximate to the ink cartridge 1, the ball member 10 is subjected to the attraction by the magnetic force thereof to close the communication port 9. When there is no such proximity of the magnet piece 12, the ball member 10 returns onto the ball member receiver 11 from its gravity as shown 20 in Figure 2B, thereby opening the communication port 9. Atmosphere-communicating means is constructed in this manner. The ink cartridge further communicates with an atmosphere-communicating tube having an opening in the upper portion of the ink cartridge through the needle tube 8B.

The ink cartridge in the embodiment as described above, when removed from the recording apparatus, has its p 1 1 communication with the atmosphere reliably cut off by the elastic member 6, and even when it is mounted in the recording apparatus, the ball member within the ink cartridge can cut off the communication with the atmosphere.

Figures 3A and 3B show a preferred embodiment of the pre-sent invention. This embodiment is an example of a liquid injection recording apparatus in which the ink cartridge 1 of the construction as described above is fixed near the home position of the body of the recording apparatus. In these figures, the reference numeral 21 designates a recording head which discharges recording liquid by the utilization of heat. The recording head 21 is carried on a carriage 22, and injects the liquid onto a recording sheet 24 to accomplish recording while being moved along a platen 23 by drive means. not shown. The recording liquid was supplied from the ink cartridge 1 to the recording head 21 through a flexible supply tube 25. A magnet piece 12A is mounted on one end of the carriage 22. When the carriage 22 was directed to the home position at the left end as shown, the magnet piece 12A was guided to the upper portion of the ink cartridge 1 as shown in Figure 3B. whereupon by the magnetic force thereof. the ball member 10 closed the communication port 9 provided in the air path 4 of the ink cartridge 1. in the manner previously shown in Figure 2A, whereby the evaporation of the recording liquid through an atmosphere-communicating tube 28 could be prevented. In these figures, the reference 1 numeral 26 designates a cap member for restoring the injecting function of an ink discharge port which is disposed at a position opposed to the recording head 21 in its home position, and the reference mumeral 27 denotes a flexible cable.

Figures 4A and 4 B show another preferred embodiment of the present invention. This embodiment is an example ofa liquid injection recording apparatus in which an ink cartridge 1, together with a recording head 221, is carried on a carriage 222. A magnet piece 12B is attached to an upright frame 230 disposed near the home position. When, as shown in Figure 4B, the carriage 222 is guided to the home position, the ink cartridge 1 carried on the carriage 222 is guided to below the magnet piece 12B, and the communication port 9 shown in Figure 2A is closed by the ball member 10.

Figures SA and 5B show another embodiment of the ink cartridge suitable for carrying out the present invention.

1 11 - The ink cartridge 201 of the present embodiment differs somewhat in the opening-closing operation from the form of the ink cartridge shown in Figures 1A and 1B. That is, the ink cartridge of the present embodiment is of a construction in which a ball member 210 formed of a magnetic material is disposed in a conical depression provided on top of a communication port 209 in an air path 204. In the other points, the construction of the ink cartridge 201 is identical to that of the ink cartridge shown in Figures 1A and 1B. The reference numeral 205 designates a cover member, the reference numeral 206 denotes a sealing elastic member, the reference character 207A designates an insertion port into which a needle tube 208A for recording liquid supply may be inserted, and the reference character 207B denotes an insertion port for a needle tube 208B communicating with the atmosphere.

The communication-port 209 of the ink cartridge is normally closed by the gravity of the ball member 210, but when subjected to a magnetic force by magnetic force generating means (not shown), the ball member 210 moves upwardly to open the communication port 209.

Thus, the ink cartridge 201 of the present embodiment can cut off the communication with the atmosphere when it is not subjected to a magnetic force.

Figures 6A and 6B show still another preferred embodiment of the present invention.

This embodiment is an example of an ink jet - - 12 1 recording apparatus in which an ink cartridge of the construction as shown in Figures 5A and 5B, together with a recording head 321, is carried on a carriage 322.

The reference numeral 331 designat6s a shaft for guiding the movement of the carriage 322, and the recording area of this shaft (for example, the position opposed to a platen 323) is provided by a magnet 321.

So, when, as shown in Figure 6B, the carriage 322 is moved to the recording area, the ball member in the ink cartridge 201 is subjected to an upward attraction by the magnet 321 to thereby open the communication port.

According to the present embodiment, only when the carriage is within the recording area, the recording liquid in the ink cartridge communicates with the atmosphere and there.fore, the evaporation of the recording liquid can be reliably prevented during the pause of recording.

In the foregoing, description has been made with respect to a case where the relative position of the magnet piece 12 and the magnetic ball member 10 in the cartidge 1 is in the vertical direction, whereas the direction is not limited to the vertical direction, but for example, the magnet may be disposed in an oblique direction so that the ball member 10 may roll by the magnetic force of the magnet to close the communication port formed in an oblique direction.

Further, in the embodiments described above, design 1 is made such that the attraction generated by the magnet moves the ball member to thereby close the communication port, but a similar operation could be performed even if design was made such-that the closing of the communication post was accomplished by the movement of the ball member caused by the repulsion generated by a magnet. Also, the opening-closing means may be of any form in which the opening-closing means is smoothly subjected to attraction or repulsion by a magnet to thereby close the communication port, and may be, for example, a plate-like valve member having one end fixed and capable of opening and closing the communication port, or a conical valve member having a tapered portion insertable into the communication port, but when cost and the like are taken into account, the ball member as in the present embodiment is more preferable.

Also, design is made such that the communication port can be opened and closed by a magnetic member and therefore, it has become unnecessary to employ a form of cartridge tank in which recording liquid enclosed in a bag is contained in a case as in the prior art, and vibration resistance and shock resistance could be improved and the whole configuration could be made compact. Also, it has become possible to prevent the evaporation of the recording liquid without resorting to a complex construction which uses an electromagnetic valve or the like, and the improved reliability of the cartridge tank could be achieved.

14 - 1 Further, when the cartridge is in its home position, it is possible to reliably close the vent path of the ink cartridge which is in communication with the atmosphere and therefore, leakage of ink from the vent port could be prevented even when the entire recording apparatus was moved during the pause of recording with the ink cartridge remaining carried thereon.

According to the present invention, in the vent path communicating with the recording liquid containing portion of the cartridge tank, there is disposed a magnetic member as opening-closing means capable of opening and closing the vent path and there is also disposed magnetic force imparting means for causing a magnetic force to act on the magnetic member, and the communication with the atmosphere can be cut off by the magnetic member when the carriage is directed to the outside of the recording area, for example, the home position. Accordingly, in the ink cartridge and the liquid injection recording apparatus according to the present invention, during the pause of recording, the recording liquid could be prevented from evaporating and could be preserved in a good condition, and during the recording operation, stable supply of the recording liquid could be effected to ensure good recording to be accomplished.

In addition according to the present invention, there could be provided a simple construction which was strong to any change in the environment and any shock 1 from the outside and in which an excellent ink cartridge capable of communicating with the atmosphere as required could be manufactured at a low cost.
