Description

  The present invention relates to an ink mist guiding device including an electrode disposed at a position facing a recording head, and a voltage applying means for applying a voltage to the electrode, a recording device including the ink mist guiding device, and a liquid The present invention relates to a liquid ejecting apparatus including a mist guiding device.

  Here, the liquid ejecting apparatus is an ink jet recording apparatus or a copying machine that performs recording on a recording medium by ejecting ink as a liquid droplet from a recording head serving as a liquid ejecting head onto a recording medium such as recording paper. In addition to a recording apparatus such as a facsimile, a liquid corresponding to a specific application instead of ink is ejected from a liquid ejecting head corresponding to the recording head to an ejecting medium corresponding to a recording medium, and the liquid is ejected. It is used in the meaning including a device that adheres to the ejection medium. In addition to the recording head described above, the liquid ejecting head includes a color material ejecting head used for manufacturing a color filter such as a liquid crystal display, an electrode material used for forming an electrode such as an organic EL display and a surface emitting display (FED) ( Examples thereof include a conductive paste) ejection head, a bio-organic matter ejection head used for biochip manufacturing, and a sample ejection head that ejects a sample as a precision pipette.

  Conventionally, an inkjet recording apparatus described in Patent Document 1 has been proposed. In this recording apparatus, an ink droplet is ejected from a nozzle opening provided in the recording head, and an electrode to which a voltage is applied by a voltage applying unit is provided at the recording head and a position facing the recording head to generate an electric field. It was generated. The flight of the ejected ink droplets was stabilized. In other words, in order to stabilize the ejection of the ejected ink droplet, an electric field is generated by applying a voltage to the electrode to induce the ink droplet.

JP-A-11-320890

However, the voltage is applied to the electrodes only for the purpose of stabilizing the flying of the ink droplets ejected from the recording head, and the so-called ink mist generated when the ink droplets are ejected from the recording head. No measures were taken.
Here, in the present application, the “ink droplet” has an amount of about 1 to 2 pl (picoliter), and when there is no electrode to which a voltage is applied on the recording head side, the ink droplet is ejected from the nozzle opening of the recording head. , Which is charged positively by friction with the nozzle opening.
On the other hand, “ink mist” is generated when an “ink droplet” is ejected from the nozzle opening of the recording head, and has an amount of approximately 1 pl or less, and a voltage is applied to the recording head side. When there is no electrode, it is charged negatively (−) due to friction with the nozzle opening.
Furthermore, “ink mist” may fly in the air without adhering to the recording medium or the like. Whether or not the “ink mist” flies in the air depends on the size, weight, speed, distance to the adhesion target, etc. of the “ink mist”.

Therefore, in the case of "ink mist" having different properties from "ink droplets", when no countermeasure is provided, the "ink mist" flies in the air, and in the area where the ink is ejected from the recording head and its surroundings, There is a risk that other members may be soiled.
In Japanese Patent Application Laid-Open No. 11-320890, the voltage applied to the electrode by the voltage applying means is set to be very high as 1 to 2 kV (kilovolt) in order to reliably induce ink droplets. Further, during the recording in which the ink droplets are ejected from the nozzle openings, the voltage application unit is operated uniformly, so that the amount of electric power consumed is large. Therefore, it was not suitable in terms of economy and environment.

  Accordingly, the present invention has been made in view of such a situation, and an object of the present invention is to provide an ink mist guiding device that prevents the contamination of other members due to the occurrence of ink mist. Furthermore, an ink mist induction device that induces ink mist generated when ink droplets are ejected from the recording head by applying a voltage to the electrodes by the voltage application means, which is unnecessary as in the case of the voltage application means. An object of the present invention is to provide an ink mist guiding device that can reduce power consumption.

  In order to achieve the above object, a first aspect of the present invention is an ink mist induction device comprising an electrode disposed at a position facing a recording head, and a voltage applying means for applying a voltage to the electrode. An ink mist induction device characterized in that, by operating the voltage application means, ink mist generated when ink droplets are ejected from the recording head is guided and adsorbed to the electrode side. .

  According to the first aspect of the present invention, by operating the voltage applying means, “ink mist” generated when ink droplets are ejected from the recording head is guided and adsorbed to the electrode side. . That is, not the “ink droplets” ejected from the recording head but the “ink mist” that may fly in the air is guided to the electrode side. Therefore, even if the “ink mist” may be stalled due to air resistance or the like and may fly into the air, the “ink mist” can be reliably guided and adsorbed to the electrode side. That is, there is no possibility that the “ink mist” will float in the air. As a result, there is no possibility that other members are soiled by the “ink mist”.

  According to a second aspect of the present invention, in the first aspect, an ink mist that absorbs the ink droplets and the ink mist is provided between the recording head and the electrode. It is a guidance device.

For example, when the “ink mist” is guided to the electrode side, the “ink mist” may be directly adsorbed to the electrode, and the electrode may be soiled.
Therefore, according to the second aspect of the present invention, in addition to the same effects as those of the first aspect, an ink absorbing material that absorbs the ink droplets and ink mist is provided between the recording head and the electrode. It has been. Therefore, when the “ink mist” is guided to the electrode side, the “ink mist” can be adsorbed to the ink absorbing material. As a result, there is no possibility that the electrode is soiled.

  According to a third aspect of the present invention, in the first or second aspect, the voltage applying unit is configured not to apply a voltage to the electrode in a predetermined recording mode. It is an ink mist guiding device.

For example, even if the voltage application unit is operated, it may not be very effective depending on the recording mode. In such a case, the power consumption is merely large, and it is desirable that the voltage applying means does not apply a voltage to the electrode.
Therefore, according to the third aspect of the present invention, in addition to the same effect as the first or second aspect, the voltage application means does not apply a voltage to the electrode in a predetermined recording mode. It is configured. Therefore, the voltage applying means can suppress the consumption of electric power corresponding to the state where no voltage is applied to the electrodes. That is, according to the recording mode, the voltage application unit can be appropriately put into a resting state to save power consumption.

  Here, the “predetermined recording mode” refers to a recording mode in which the “ink mist” has no possibility of flying in the air. Whether or not the “ink mist” flies in the air is determined by the size, weight, speed, distance to the adhesion target, and the like of the “ink mist”.

A fourth aspect of the present invention is the ink mist guiding device according to the third aspect, wherein the predetermined recording mode is a margined recording mode or a large dot recording mode.
Unlike the so-called “marginless recording mode”, the “marginless recording mode” does not cause “ink droplets” to come off the edge of the recording medium and be ejected toward the discard groove of the platen. Accordingly, the “ink mist” generated when the “ink droplet” is ejected hardly flies away from the edge of the recording medium toward the discard groove of the platen. That is, since the “ink mist” is separated from the edge of the recording medium, the distance to the adhesion target is extended, and there is no risk of receiving additional air resistance by the extended distance. There is almost no risk of dancing.

Further, in the “large dot recording mode”, since “ink droplets” ejected from the recording head are larger than usual, there is no possibility of occurrence of “ink mist”. Even if it occurs, since a larger Coulomb force than usual is generated between “larger ink droplets” and “ink mist” than usual, they are immediately drawn together.
Therefore, it is preferable to save the amount of power used by the voltage application means in a resting state in the “bordered recording mode” and the “large dot recording mode”.

  Therefore, according to the fourth aspect of the present invention, in addition to the same effects as those of the third aspect, the “predetermined recording mode” is a “bordered recording mode” or a “large dot recording mode”. It is characterized by that. Therefore, in the “bordered recording mode” or the “large dot recording mode”, the voltage application unit can suppress wasteful consumption of the electric power corresponding to the resting state.

  According to a fifth aspect of the present invention, in the third or fourth aspect, the voltage application unit applies a voltage to the electrode when the recording apparatus operates with an internal battery in addition to the predetermined recording mode. An ink mist guiding device is characterized in that it is configured not to perform the above.

When the recording apparatus operates with the built-in battery, the amount of power that can be consumed is limited to the amount of power stored in the built-in battery. In some cases, recording on a large number of recording media with a limited amount of power is required.
Therefore, according to the fifth aspect of the present invention, in addition to the same function and effect as the third or fourth aspect, the voltage applying means operates the recording apparatus with an internal battery in addition to the predetermined recording mode. When performing, it is comprised so that a voltage may not be applied to the said electrode. Therefore, the voltage application means can suppress the consumption of electric power corresponding to the state in which no voltage is applied to the electrodes. In other words, in a state where the amount of power that can be consumed is limited, the voltage application unit is uniformly suspended, so that the amount of power used can be saved. As a result, it is possible to efficiently perform recording on the large number of recording media with a limited amount of power.

According to a sixth aspect of the present invention, there is provided a recording unit that performs recording on a recording medium by a recording head, and ink mist induction that guides ink mist generated when ink droplets are ejected from the recording unit to the electrode side. An ink mist guiding device comprising the ink mist guiding device according to any one of the first to fifth aspects. is there.
According to the sixth aspect of the present invention, the recording apparatus includes the ink mist guiding device described in any one of the first to fifth aspects. The same effect as any of the 5 aspects can be obtained.

  According to a seventh aspect of the present invention, there is provided a liquid ejecting apparatus including a liquid mist guiding device including an electrode disposed at a position facing the liquid ejecting head and a voltage applying unit that applies a voltage to the electrode. The liquid ejecting apparatus is characterized in that by operating the voltage applying means, liquid mist generated when liquid droplets are ejected from the liquid ejecting head is guided and adsorbed to the electrode side. .

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is an overall perspective view showing an outline of a recording apparatus according to the present invention. FIG. 2 is an overall plan view showing an outline of the recording apparatus according to the present invention.
On the back side of the main body of the recording apparatus 100, a paper feed cassette 101 on which sheets P (see FIG. 3) as recording media are stacked is detachably provided. The paper P stacked on the top of the paper feed cassette 101 is picked up by a feed roller (not shown) driven by a feed motor 104 and conveyed downstream in the transport direction while being guided by a paper guide 103. It is fed to a roller (not shown). The paper P fed to the transport roller is further transported to the recording unit 143 on the downstream side in the transport direction by a transport roller driven by a transport motor (not shown). The recording unit 143 includes a platen 105 that supports the paper P from below and a carriage 107 that is provided to face the upper side of the platen 105. Among them, the carriage 107 is driven by the carriage motor 102 while being guided by a carriage guide shaft (not shown) extending in the main scanning direction. Further, a recording head 106 that discharges ink toward the paper P is provided on the bottom surface of the carriage 107. The paper P recorded by the recording unit 143 is further conveyed downstream, and is discharged from the front side of the recording apparatus 100 by a paper discharge roller (not shown).

  Further, an ink cartridge (not shown) is loaded below the main body of the recording apparatus 100, and ink is supplied to an ink supply path (not shown) via an ink supply needle (not shown). Further, the ink is supplied to the recording head 106 of the carriage 107 via the ink supply tube 110. When the recording head 106 is flushed and cleaned, ink is ejected and sucked in the ink suction device 200 that is provided on the first digit side and maintains the ejection characteristics of the recording unit 143.

  Further, a concave platen recess 105 a is formed on the surface of the platen 105 facing the recording head 106. An ink absorbing material 308 that absorbs ink is disposed on the upper side of the platen recess, and an ink mist guide, which will be described later, is an example of a liquid mist guide device on the lower side (bottom side) of one platen recess 105a. An electrode plate 304 constituting the device 300 is provided.

FIG. 3 is a schematic view of an ink mist guiding device according to the present invention.
As shown in FIG. 3, the recording apparatus 100 is provided with an ink mist guiding device 300. The ink mist guiding device 300 includes an electric unit 309 and an electrode plate 304. Among these, the electrical unit 309 is an ASIC (Application) as a circuit for generating a current.
SPECIFIC INTEGRATED CIRCUIT) 307, high voltage circuit 305 for making the electricity flowing from ASIC 307 a high voltage, and the state where the flow of electricity from ASIC 307 to high voltage circuit 305 / the state where the flow of electricity is stopped, that is, the operation of high voltage circuit 305 is turned ON / OFF It is comprised from the control part 306 which switches an OFF state. Here, the position of the control unit 306 is not limited to the upstream side in the direction in which the current of the high voltage circuit 305 flows, and may of course be the downstream side of the high voltage circuit 305. This is because the voltage application to the electrode plate 304 can be switched ON / OFF as long as it is upstream from the electrode plate 304 even on the downstream side.

  Further, a nozzle opening row 302 including nozzle openings 301 for ejecting ink droplets is provided on the lower surface of the recording head 106, and an electrode plate 304 is disposed at a position facing the nozzle opening forming surface 303 which is the lower surface of the recording head 106. Is provided. The electrode plate 304 is electrically connected to the high voltage circuit 305, and the high voltage circuit 305 is provided to apply a voltage to the electrode plate 304. A specific position of the electrode plate 304 is a lower side of the sheet-like ink absorbing material 308 (see FIG. 1) disposed in a recess formed in the platen 105. That is, during recording, the nozzle opening forming surface 303, the paper P, the ink absorbing material 308, and the electrode plate 304 are arranged in this order from the recording head side to the platen side.

  When the control unit 306 is in the ON state, electricity flows from the ASIC 307 to the high voltage circuit 305. The high voltage circuit 305 applies a voltage of 4 to 4000 V to the electrode plate 304. Therefore, an electric field can be generated in the space around the electrode plate 304. At this time, since the electrode plate 304 is (+) plus charge, the (−) minus charge can be attracted by the Coulomb force in the space around the electrode plate 304.

Normally, during recording, “ink droplets” are ejected from the nozzle opening row 302 of the recording head 106, and “ink mist” is generated when “ink droplets” are ejected. The “ink droplets” land on the paper P, and one “ink mist” adheres to the paper P.
However, in the so-called “edgeless recording mode”, when recording the side edges and upper and lower ends of the paper P, some “ink droplets” and “ink mist” do not land on or adhere to the paper P. It deviates outward from the end and upper and lower ends, and flies toward the ink absorbing material 308 disposed in the platen recess 105a. At this time, since the flight distances of the “ink droplet” and “ink mist” are extended, the “ink droplet” and “ink mist” receive extra air resistance by the extended distance. Further, at this time, the “ink mist” of “ink droplet” and “ink mist” has a smaller amount than the “ink droplet”, and thus is easily affected by air resistance. Therefore, the “ink mist” may stall and float in the air.
Here, the “ink droplet” has an amount of about 1 to 2 pl (picoliter), and when there is no electrode to which voltage is applied on the recording head side, the ink droplet is ejected from the nozzle opening 301 of the recording head 106. This means that (+) plus is charged by friction with the nozzle opening 301.
On the other hand, the “ink mist” is generated when an “ink droplet” is ejected from the nozzle opening 301 of the recording head 106, has an amount of approximately 1 pl or less, and a voltage is applied to the recording head side. When there is no electrode formed, it is charged negatively due to friction with the nozzle opening 301.
Furthermore, “ink mist” may fly in the air without adhering to paper or the like. Whether or not the “ink mist” flies in the air depends on the size, weight, speed, distance to the adhesion target, etc. of the “ink mist”.

As described above, when the above-described electric field is generated in the space around the electrode plate 304 in the “borderless recording mode” in which “ink mist” is likely to occur, the “ink mist” is guided to the electrode plate 304. be able to. That is, the (−) minus charge of the “ink mist” and the (+) plus charge of the electrode plate 304 are attracted to each other by the Coulomb force. As a result, the “ink mist” is attracted to the electrode plate side. Therefore, the “ink mist” can be adsorbed to the ink absorbing material 308 disposed in front of the electrode plate 304. As a result, since the “ink mist” does not float in the air, there is no possibility that the periphery of the recording unit is soiled.
Since both the ink droplet and the electrode plate 304 are (+) plus charge, a force that repels each other, that is, a force that stalls the ink droplet, acts, but the ink droplet absorbs the paper P or ink before it stalls. Land on the material 308. At this time, it is desirable that the voltage value of the electrode plate 304 is set so as not to act on a large amount of ink droplets but only to a small amount of ink mist. In other words, it is desirable to set the minimum voltage value that acts only on the ink mist that is easily affected by the electric field. In this case, the amount of ink mist is very small compared to the amount of ink droplets, and therefore the voltage value can be set very low compared to the voltage value required for inducing ink droplets in the prior art. it can.

  The ink mist guiding apparatus 300 according to this embodiment includes an electrode plate 304 as an electrode disposed at a position facing the recording head 106, and an electric unit 309 as a voltage applying unit that applies a voltage to the electrode plate 304. Ink mist guiding device 300, by operating electric section 309 as voltage applying means, “ink mist” generated when “ink droplets” are ejected from recording head 106 is transferred to the electrode plate side. It is characterized by being induced to adsorb. That is, not the “ink droplets” ejected from the recording head 106 but the “ink mist” that may fly in the air is guided to the electrode plate side.

  As a result, the “ink mist” can be reliably guided and adsorbed to the electrode plate side even in a state where the “ink mist” may stall in the air due to air resistance or the like. That is, there is no possibility that the “ink mist” will float in the air. Therefore, there is no possibility that the “ink mist” may contaminate other members around the recording portion.

For example, when the “ink mist” is guided to the electrode plate side, the “ink mist” may be directly adsorbed to the electrode plate 304 and the electrode plate 304 may be soiled.
Therefore, the ink mist guiding device 300 of the present embodiment is characterized in that an ink absorbing material 308 that absorbs “ink droplets” and “ink mist” is provided between the recording head 106 and the electrode plate 304. To do.
As a result, when the “ink mist” is guided to the electrode plate side, the “ink mist” can be adsorbed to the ink absorbing material 308. Therefore, there is no possibility that the electrode plate 304 is soiled.

  However, depending on the recording mode, there is a possibility that the “ink mist” may float in the air. For example, “a bordered recording mode” or “a large dot recording mode”. In the “bordered recording mode”, “ink droplets” are always ejected to the inner side of the paper edge. Accordingly, the “ink mist” generated when the “ink droplet” is ejected is generated on the inner side of the paper edge. That is, the flying distance of “ink droplet” and “ink mist” does not increase. Therefore, there is no possibility that the “ink mist” will float in the air. On the other hand, in the “large dot recording mode”, “ink droplets” ejected from the nozzle openings 301 are larger than usual, and there is no possibility of occurrence of “ink mist”. Even if it occurs, since a larger Coulomb force than usual is generated between “larger ink droplets” and “ink mist” than usual, they are immediately drawn together.

In such a recording mode in which “ink mist” is not likely to float in the air, even if the above-described electric field is generated in the space around the electrode plate 304, the effect cannot be obtained so much. When a voltage is applied to the electrode plate 304, the power consumption P is generally given by the following equation:
P = I · V · t (P: electric energy, I: current, V: voltage, t: time)
The amount of power P is proportional to the voltage V. Therefore, if a high voltage is applied to the electrode plate 304, the amount of power consumed increases. At this time, if it is not effective to generate the electric field described above, it can be said that most of the consumed electric energy is unnecessary.
Therefore, when the user selects “recording mode”, the control unit 306 is provided to automatically switch ON / OFF, which is the operating state of the high voltage circuit 305, according to the recording mode.

When recording is executed, the user first selects a recording mode. Next, the recording data is sent to the recording unit 143 and the paper P is transported to the recording unit 143 by the transport roller. At this time, if the selected recording mode is the “marginless recording mode”, the control unit 306 turns on the high voltage circuit 305, and ink droplets are ejected from the nozzle openings 301 to the paper P. Is started. That is, ink droplets are ejected from the nozzle openings 301 in a state where the high voltage circuit 305 is activated and the electric field described above is generated in the space around the electrode plate 304. Then, along with the end of recording, the control unit 306 turns off the high voltage circuit 305.
Here, in order to surely adsorb the “ink mist” to the ink absorbing material 308, it is of course possible to place the high voltage circuit 305 in the OFF state, which is a pause state, after a certain time lag is provided after the recording is completed. .

  On the other hand, when the selected recording mode is the “bordered recording mode” or the “large dot recording mode”, the control unit 306 switches the high voltage circuit 305 to the OFF state from the time when the mode is selected. Therefore, even when recording is started, the high voltage circuit 305 does not operate, and thus the electric field described above does not occur in the space around the electrode plate 304.

In the present embodiment, the electrical unit 309 as voltage application means is configured not to apply a voltage to the electrode plate 304 in the “predetermined recording mode”. Specifically, the electric unit 309 causes the control unit 306 to turn the high voltage circuit 305 to an OFF state that is a dormant state.
As a result, the electric unit 309 that is a voltage applying unit can suppress the consumption of electric power that is not applied to the electrode plate 304. That is, according to the recording mode, the electric unit 309 that is a voltage application unit can appropriately save power consumption by being in an OFF state that is a dormant state.

  Here, the “predetermined recording mode” refers to a recording mode in which the “ink mist” has no possibility of flying in the air. Whether or not the “ink mist” flies in the air depends on the size, weight, speed, distance to the adhesion target, and the like of the “ink mist”.

  In the “bordered recording mode”, unlike the so-called “borderless recording mode”, ink droplets are not discharged from the edge of the paper P toward the discarding grooves that are part of the platen recess 105a. Therefore, the ink mist generated when the ink droplets are ejected hardly flies away from the edge of the paper P toward the discard groove that is a part of the platen recess 105a. That is, since the “ink mist” is separated from the edge of the paper P, the distance to the adhesion target is extended, and there is no possibility of receiving additional air resistance by the extended distance. There is almost no fear.

Further, in the “large dot recording mode”, since “ink droplets” ejected from the nozzle openings 301 of the recording head 106 are larger than usual, there is no possibility of generating “ink mist”. Even if it occurs, since a larger Coulomb force than usual is generated between “larger ink droplets” and “ink mist” than usual, they are immediately drawn together.
Accordingly, it is preferable to save the amount of power used by turning off the electrical unit 309 as the voltage applying means in the “bordered recording mode” and the “large dot recording mode”.

Therefore, the “predetermined recording mode” of the present embodiment is characterized by being a “bordered recording mode” or a “large dot recording mode”.
As a result, in the “bordered recording mode” or the “large dot recording mode”, the electrical unit 309 can suppress wasteful consumption of the amount of power corresponding to the OFF state.

  Further, if the recording apparatus 100 can be carried and carried, a built-in battery (not shown) may be provided inside the recording apparatus. In this case, the control unit 306 automatically turns off the high voltage circuit 305 when the recording apparatus 100 operates with the built-in battery regardless of whether or not the “predetermined recording mode” is selected. Is provided.

When the recording apparatus 100 operates with the built-in battery, the amount of power that can be consumed is limited to the amount of power stored in the built-in battery. In some cases, recording must be performed on a large number of sheets P with a limited amount of power. That is, in order to execute recording on the paper P, it is necessary to preferentially spend power on the feeding motor 104, the carriage motor 102, and the like.
In such a case, since the control unit 306 turns off the high voltage circuit 305, it is possible to suppress consumption of the amount of power corresponding to the turning off state.

In addition to the “predetermined recording mode”, the electrical unit 309 that is a voltage applying unit of the present embodiment is configured not to apply a voltage to the electrode plate 304 when the recording apparatus 100 is operated by the built-in battery. It is characterized by that. Specifically, the electrical unit 309 causes the control unit 306 to turn off the high voltage circuit 305.
As a result, the electrical unit 309 can suppress consumption of the amount of power that is not applied to the electrode plate 304. That is, in a state where the amount of power that can be consumed is limited, the electric unit 309 is uniformly turned off, so that the amount of power used can be saved. Accordingly, it is possible to efficiently execute recording on a large number of sheets P with a limited amount of power.

  The recording apparatus 100 according to the present embodiment includes a recording unit 143 that performs recording on a sheet P as a recording medium by the recording head 106, and “ink mist” that is generated when “ink droplets” are ejected from the recording unit 143. The recording apparatus 100 includes an ink mist guiding device 300 that guides the ink mist to the electrode plate side, and includes the ink mist guiding device 300 described above.

  As a result, the recording apparatus 100 can obtain the same effects as those obtained with the ink mist guiding device 300.

In the present invention, the “ink mist” is not only generated at the nozzle opening when the “ink droplet” is ejected, but also the large “ink droplet” ejected from the nozzle opening is “ Needless to say, it includes ink droplets having a small amount of (−) minus charge generated separately from a part of “ink droplets”.
Further, the present invention is not limited to the above-described embodiments, and various modifications are possible within the scope of the invention described in the claims, and these are also included in the scope of the present invention. Needless to say.
