  The present invention relates to a recording apparatus, and more particularly to a recording apparatus having a structure for reducing noise generated during operation of the recording apparatus.

In general, a recording apparatus such as an ink jet printer, a laser printer, or a facsimile has a supply port for supplying a recording medium such as paper or film to be recorded into a recording mechanism, and a discharge port for discharging the recording medium after recording. Since it is in an open state, the operation sound of the transport mechanism and the recording mechanism leaks to the outside from the supply port and the discharge port, which is one of the factors that cause noise during the printing operation.
Therefore, a device for suppressing sound leakage by providing a sound insulation plate that opens and closes the opening of the recording medium supply port and discharge port of the recording apparatus and opening and closing the sound insulation plate in conjunction with the supply and discharge of the recording medium is disclosed. Has been.
However, since the recording apparatus enables the supply port and the discharge port to be closed during the operation of the recording mechanism, a space for accommodating the recording medium in a curved state before the recording operation is bent more than necessary. Therefore, it is necessary to provide a space for storing the recording medium after being recorded in a curved state before discharging the recording medium, which increases the size of the recording apparatus. Further, when the space is reduced, the curvature of the recording medium to be accommodated is reduced, so that depending on the thickness of the recording medium and the material, there is a concern that the recording medium after ejection may be wound or bent.

However, the following embodiments do not limit the invention according to the claims, and all combinations of features described in the embodiments are included in the invention. It is not necessarily essential to the solution, but includes a configuration that is selectively adopted.

Embodiment 1
FIG. 1 is a schematic view of a recording apparatus 1 according to the present invention when viewed from a side cross section.
A recording apparatus 1 shown in FIG. 1 is a liquid ejecting apparatus as an example of a recording apparatus. Hereinafter, the recording apparatus 1 will be described with reference to FIG.
In FIG. 1, a recording apparatus 1 includes a storage chamber 3 that is provided at the bottom of the apparatus body 2 and stores a sheet 10 as an example of a recording medium.
Further, the recording apparatus 1 includes a feeding unit 4 that feeds the paper 10 accommodated in the storage chamber 3 to the downstream side, and a feeding mechanism 5 that transports the paper 10 sent by the sending unit 4 to the recording unit 6 side. Is provided. The paper 10 accommodated in the accommodation chamber 3 is conveyed by the delivery means 4 and the conveyance roller 5 to the recording unit 6 located on the downstream side along the conveyance path indicated by the arrow, and characters, graphics, etc. are printed on the surface. . In the present specification, the direction in which the paper 10 accommodated in the storage chamber 3 is conveyed is described as the downstream side, and the direction opposite to the downstream side is described as the upstream side.

Hereinafter, the details of the recording apparatus 1 will be described along the conveyance path of the recording medium.
The storage chamber 3 is constituted by a box-shaped cassette 11 that is open upward, for example. The cassette 11 can be mounted in an insertion space provided on one side of the apparatus main body 2 and accommodates the paper 10 in a single or superimposed state. The cassette 11 is held at a predetermined position by a guide (not shown) provided in the insertion space. When the cassette 11 is taken out, it can be taken out from the apparatus main body 2 by pulling it out upstream along a guide (not shown).
Further, the cassette 11 has a wall portion surrounding the periphery of the paper 10 to be accommodated, and one wall portion positioned on the downstream side is formed as a separation slope 13. The separation slope 13 is a slope that slopes downstream as it goes upward from the cassette bottom surface 11A. The separation slope 13 prevents the plurality of sheets 10 accommodated in the accommodation chamber 3 from being conveyed downstream in a state where they overlap each other.

  Specifically, as shown in FIG. 1, the end portion 10 </ b> A of the uppermost sheet 10 rises upward while being in sliding contact with the separation slope 13 by rotational driving in one direction of the delivery roller 41. Become. Further, as the uppermost sheet 10 is conveyed to the downstream side, the lower sheet 10 that is about to be sent out overlaps the separation slope 13 and is separated from the upper sheet 10. That is, the separation slope 13 is a slope that prevents double feeding.

Next, the sending means 4 will be described.
The sending means 4 is a mechanism for sending the paper 10 accommodated in the cassette 11 to the guide passage 70 on the downstream side. The feeding means 4 has a swinging body 42 having a feeding roller 41 that contacts the surface of the uppermost sheet 10 accommodated in the cassette 11 and a biasing means for biasing the swinging body 42 in the direction of the sheet 10 existing below. 43 and a rotation shaft 55 for rotating the delivery roller 41. The oscillating body 42 is connected to a cylindrical rotating shaft 48 extending in a direction orthogonal to the conveyance direction of the paper 10. The rotating shaft 48 is supported by a bearing provided on a frame (not shown) in the apparatus main body 2. That is, the oscillating body 42 can rotate in the vertical direction around the rotation shaft 48.

  In addition, a toothed wheel train 50 is provided in the oscillating body 42 by a plurality of gears arranged along the longitudinal direction. The toothed wheel train 50 is supported by a shaft that is inserted into a plurality of holes 54 provided on the side surface of the rocking body 42, and transmits the rotational force of the rotating shaft 55 to the delivery roller 41.

  The rotating shaft 55 is a shaft body that rotates independently within the rotating shaft 48. The rotation shaft 55 is longer than the extension length of the rotation shaft 48, and a rotational force from a drive motor (not shown) is input to one end exposed from the rotation shaft 48. The other end of the rotating shaft 55 passes through the side surface of the rocking body 42 and is connected to the gear 63 in the rocking body 42. Therefore, the rotational force input to the gear 63 from the drive motor (not shown) is transmitted to the tooth wheel train 50 and the gear 57 that meshes with the last gear constituting the tooth wheel train 50, and the lower end of the oscillator 42. The feed roller 41 provided in the direction is rotated in one direction.

  The delivery roller 41 is a roller also called a pickup roller, and is a rotating body whose surface is covered with a non-slip member such as rubber, for example. The delivery roller 41 is a cylindrical body having a larger diameter than the outer diameter of the gear 57 that rotates integrally. The center axis of the delivery roller is supported by the hole 54 and rotates as the gear 57 rotates. The feeding roller 41 contacts the upper surface of the paper 10 accommodated in the cassette 11 in a state where the swinging body 42 is urged toward the paper 10 by the urging means 43 such as a coiled torsion spring. Then, when the delivery roller 41 rotates in contact with the upper surface of the paper 10, the paper 10 in contact with the delivery roller 41 is sent out downstream.

As shown in FIG. 1, the sheet 10 delivered from the cassette 11 by the rotation of the delivery roller 41 is lifted at the end 10 </ b> A by passing through the separation slope 13, and enters the guide passage 70 provided in the apparatus main body 2. . The guide passage 70 is a supply passage for taking in the sheet 10 accommodated in the cassette 11 into the apparatus main body 2, and gradually curves from the upstream side to the downstream side as it goes upward.
The sheet 10 whose end portion 10A is lifted through the separation slope 13 enters from the supply port 15 provided on the cassette 11 side of the guide passage 70, and is gradually taken into the apparatus main body 2 while the front and back sides are reversed.
The guide passage 70 is a gap formed between the guide portions 77 and 78 provided in the apparatus main body 2. The guide portions 77 and 78 are members extending in a direction orthogonal to the transport direction, and are installed between frames outside the figure of the apparatus main body 2. Therefore, the guide passage 70 can capture the entire digit direction (width direction) of the paper 10.
Further, the lower part of the opening 15 corresponding to the paper 10 take-in port in the apparatus main body 2 is closed by the cassette 11 mounted in the insertion space. It is possible to reliably prevent the noise inside from being released to the outside of the recording apparatus 1.

A transport roller 5 is provided in the path in the guide passage 70. The transport roller 5 is a group of rollers that is also called an intermediate roller, and is composed of a pair of rollers, for example, a drive roller 75 and a driven roller 76.
The driving roller 75 and the driven roller 76 are constituted by, for example, cylindrical rubber rollers, and are supported by a rotating shaft that is installed between frames that are not shown. The driving roller 75 and the driven roller 76 are arranged so that the outer surfaces are in contact with each other. For example, the driving roller 75 rotates via a plurality of gears using a motor (not shown) that rotates the delivery roller 41 as a driving source. Therefore, when the end portion 10 </ b> A of the sheet 10 that has entered the guide passage 70 reaches the transport roller 5, it passes through the guide passage 70 while being pulled up so as to be sandwiched between the driving roller 75 and the driven roller 76.

The sheet 10 whose front and back sides are reversed through the guide passage 70 is conveyed toward the recording unit 6 while being kept substantially horizontal along a conveyance surface 82 having ribs and auxiliary rollers 79A, 79B, 80A, 80B (not shown). .
The recording unit 6 includes a recording head 81 arranged to be movable in the digit direction on the conveyed paper 10 and a capping mechanism 85 arranged on one side of the digit direction and facing the recording head 81 in the vertical direction. .
The recording head 81 is provided on the lower surface of the carriage 84 that slides along a guide shaft 83 spanned between frames not shown.
The carriage 84 includes an ink cartridge in which a liquid of a color such as cyan, magenta, yellow, or black is sealed in a liquid storage chamber formed therein. The carriage 84 is connected to a timing belt (not shown), and reciprocates along the digit direction of the paper 10 when the timing belt moves in the digit direction by driving a driving motor (not shown).
The ink in the ink cartridge is ejected from a nozzle surface formed on the lower end surface of the recording head 81 through a predetermined control through an ink flow path formed in the carriage 84 and the recording head 81.
In the present embodiment, an example in which the ink cartridge is mounted in the carriage 84 has been described. However, the ink cartridge is stored in a storage unit different from the carriage 84, and the ink is stored in the recording head 81 via the ink supply tube. A so-called off-carriage configuration may be adopted. The capping mechanism 85 has a cap that seals the nozzle surface formed on the lower end surface of the recording head 81, and is a mechanism that keeps the nozzle surface and the ink flow path in a wet state. The recording head 81 of the recording unit 6 ejects liquid while reciprocating on the paper 10 being conveyed, whereby desired characters and shapes are gradually printed on the paper 10.

The paper 10 that has passed through the recording unit 6 is gradually conveyed downstream by driving the discharge rollers 86A and 86B, and is held in the discharge mechanism 20 via the discharge mechanism guide passage 16 provided on the downstream side of the recording unit 6. Is done. Hereinafter, the details of the discharge mechanism guide passage 16 and the discharge mechanism 20 will be described.
The discharge mechanism guide passage 16 is formed by a guide portion 18 and a guide portion 19. The guide portion 18 and the guide portion 19 are members that extend in a direction orthogonal to the transport direction, similar to the guide portion 77 and the guide portion 78 described above, and are installed between frames outside the figure of the apparatus main body 2. Therefore, the discharge mechanism guide passage 16 can take in the whole area of the paper 10 in which the printing is completed in the digit direction.
The guide unit 18 has an inclined surface 18A that changes the transport direction of the sheet 10 transported substantially horizontally upward. The guide portion 19 has a fan shape in cross section and has an isolated surface 19A facing the inclined surface 18A. Then, the sheet 10 is gradually guided to the discharge mechanism 20 side while gradually rising in the vertical direction by passing between the inclined surface 18A and the isolated surface 19A.

FIG. 2 is a perspective view showing the discharge mechanism 20.
Hereinafter, details of the discharge mechanism 20 will be described with reference to FIGS. 1 and 2. The discharge mechanism 20 includes an open / close lid 21 that closes the opening 2 </ b> A that opens downstream in the apparatus main body 2, and a holding unit 22 that holds the paper 10 after printing is completed.
The opening / closing lid 21 is a rectangular flat plate larger than the sheet 10 having a size that can be printed by the recording apparatus 1, and closes the entire area of the opening 2 </ b> A formed substantially in the same shape as the opening / closing lid 21 in the closed state.
The opening / closing lid 21 is provided to the apparatus main body 2 such that the lower side of the opening / closing lid 21 is open to the apparatus main body 2. Specifically, as shown in FIG. 2, a convex portion 21 </ b> A that protrudes in a direction perpendicular to the conveying direction is formed on the upper part of the opening / closing lid 21, and the convex portion 21 </ b> A is engaged with the apparatus body 2 that is not shown By being fitted into the hole, the opening / closing lid 21 opens and closes around the convex portion 21A as a rotation center.

As shown in FIG. 2, an opening / closing mechanism including a motor 25 and a link mechanism 26 is connected to the side of the opening / closing lid 21. The motor 25 is disposed on one of the frames (not shown) constituting the apparatus main body 2 and is driven based on a control signal output from a control device mounted on the apparatus main body 2.
The motor 25 has a gear 27 for transmitting a driving force to the link mechanism 26, and meshes with a gear 30 of a link piece 28 constituting one link mechanism 26. One link mechanism 26 has a gear piece 30 at one end and a link piece 28 having a sliding piece 29 at the other end. The gear 30 is supported by a rotating shaft (not shown) and rotates integrally with the link piece 28. The sliding piece 29 is inserted into a groove 21B extending in the vertical direction on the side of the opening / closing lid 21, and is slidable in the vertical direction within the groove 21B. The link piece 28 and the sliding piece 29 are rotatably connected via a rotating shaft. The other link mechanism 26 is different from the one link mechanism 26 only in that it does not have the gear 30 and therefore will not be described. However, one end of the link piece 28 is supported by a rotation shaft (not shown). Yes.

FIG. 3 is a side view showing the opening / closing operation of the opening / closing lid 21.
As shown in FIG. 3A, the motor 25 of the opening / closing mechanism connected to the opening / closing lid 21 is unidirectional in a state where the opening / closing lid 21 stands in the vertical direction, that is, the opening / closing lid 21 closes the opening 2A. , The link piece 28 rotates upward through the gear 30. When the link piece 28 starts to rotate upward, the sliding piece 29 pushes up the opening / closing lid 21 while sliding in the groove 21 </ b> B, and the lower end of the opening / closing lid 21 extends from the opening 2 </ b> A of the apparatus body 2. A discharge port is formed between the opening 2 </ b> A of the apparatus body 2 and the opening / closing lid 21.
On the other hand, when the motor 25 rotates in the reverse direction, the link piece 28 rotates downward via the gear 30. When the link piece 28 starts to rotate downward, the sliding piece 29 pushes down the opening / closing lid 21 while sliding in the groove 21B, and the lower end of the opening / closing lid 21 pushes the opening 2A of the apparatus main body 2. Block again. That is, the opening / closing lid 21 is a member that opens and closes so as to close or open the opening 2A formed on the downstream side of the apparatus main body 2, and is a member that opens downward when opening the opening 2A.

Next, the holding means 22 provided on the upstream side surface of the opening / closing lid 21 will be described with reference to FIGS. 1 and 2. The holding means 22 includes a rectangular plate 31 having a size substantially equal to the area of the sheet 10 conveyed from the upstream side, guide portions 32 formed on both sides of the rectangular plate 31, and the sheet 10 along the guide portion 32. And a roller 34 to be pulled up. The guide portion 32 has an L-shaped cross section composed of a guide piece 32A standing upright from the side of the rectangular plate 31 and a guide piece 32B bent in the right-angle direction from the guide piece 32A. Guide to surround.
Further, as shown in FIG. 1, in the state where the open / close lid 21 is closed, the interval between the rectangular plate 31 and the guide piece 32B facing the rectangular plate 31 is substantially equal to the interval between the guide portions 18; Are equally spaced. Therefore, the sheet 10 that has passed through the outlet of the discharge mechanism guide passage 16 smoothly enters the guide portion 32.

  For example, the outer surface of the roller 34 is formed of rubber or the like, and is rotatably supported by a rotation shaft that is installed between the guide pieces 32A. The roller 34 is disposed on the lower end side of the rectangular plate 31 and pulls up the paper 10 that has entered the guide portion 32 through the guide portions 18 and 19 along the extending direction of the guide piece 32A. More specifically, as shown in FIG. 1, the roller 34 is disposed such that the outer peripheral surface is slightly in contact with or slightly separated from the surface of the rectangular plate 31. The paper 10 that has entered the guide portion 32 is gradually pulled up in the vertical direction while being sandwiched between the roller 34 and the rectangular plate 31, and the rear end portion of the paper 10 is completely taken into the guide portion 32. The print surface is directed upstream in the transport direction, and held while maintaining a vertical posture. That is, the holding means 22 provided in the opening / closing lid 21 is a mechanism that can hold the paper 10 after printing is completed without being bent, bent, or the like. Further, since the opening / closing lid 21 is in a state in which the opening 2A is closed during the printing operation by the recording head 81 and the conveying operation to the holding means 22, noise generated during the printing operation and the conveying operation is externally generated from the opening 2A. Can be surely prevented from being released.

With reference to FIGS. 3A and 3C, an operation of discharging the paper 10 held by the discharge mechanism 20 to the outside of the apparatus main body 2 will be described.
When the paper 10 entering the guide portion 32 is pulled up to a predetermined position by driving the roller 34 and the holding operation of the paper 10 by the guide portion 32 is completed, the opening / closing lid 21 is opened by driving the motor 25, and FIG. It will be in the state shown in
When the roller 34 is driven in the direction opposite to the pulling direction with the opening / closing lid 21 opened, the paper 10 held in the guide portion 32 is fed out from the lower end portion of the guide portion 32 so that the print surface faces downward. It is discharged from the apparatus main body 2 so as to be injected in a state.
At this time, the paper 10 discharged from the apparatus main body 2 is placed on a paper tray such as a tray (not shown) with the printing surface facing downward. After the discharge of the paper 10 is completed, the open / close lid 21 is closed again by the reverse rotation of the motor 25, and one printing operation in the recording apparatus 1 from paper feeding, printing, and discharging is completed. In addition, when the print target extends over a plurality of sheets 10, the above-described printing operation is repeated.

According to the recording apparatus 1 according to the above-described embodiment, noise generated during the conveying operation of the paper 10 from the cassette 11 to the apparatus main body 2, the printing operation of the recording head 81, and the conveying operation to the discharge mechanism 20 is generated. Since the configuration does not leak to the outside, the printing operation on the paper 10 can be performed extremely quietly. More specifically, since the printing operation is executed in a state where the opening 2A having a high contribution of noise emission is closed by the opening / closing lid 21, it is possible to effectively prevent the noise generated by the printing operation from leaking to the outside. Can be prevented. Further, since the paper 10 on which printing has been completed is held in a substantially vertical posture by the holding means 22, it can be discharged to the outside without causing deformation of the paper 10. That is, the recording apparatus 1 according to the present embodiment has an extremely remarkable effect that the shape after ejection is not changed regardless of the type of the recording medium while ensuring the quietness during the printing operation. is there.
Further, the opening / closing lid 21 that closes the opening 2A opens downward with the convex portion 21A positioned above as the rotation center, and discharges the paper 10 held by the holding means 22 provided on the opening / closing lid 21 from the lower end side. Because of the configuration, the discharged paper 10 is in a state where the printing surface faces downward. Therefore, in the case of printing data over a plurality of pages, the sheet 10 on which the first page is printed is positioned at the bottom, and the sheets 10 on which the next page and subsequent pages are printed are sequentially stacked. When printing for all data is completed, the first sheet 10 corresponds to the first page in the data, and the subsequent sheets 10 correspond to the next page, so that the plurality of sheets 10 correspond to the page order in the data. Can be made. That is, it is possible to save the trouble of rearranging the order of the sheets 10 after the printing is completed.

In the above-described embodiment, the height of the opening / closing lid 21 and the holding unit 22 is set to a height corresponding to the transport direction length of the paper 10 in order to hold the paper 10 in a vertical posture. The height of the opening / closing lid 21 and the holding means 22 is not limited to this.
For example, the height of the opening / closing lid 21 and the holding means 22 is set to about half the height of the opening / closing lid 21 and the holding means 22 in the embodiment, and the upper half of the paper 10 held by the holding means 22 is set upstream. You may make it hold | maintain in the curved state. According to this aspect, although the curvature of the paper 10 is allowed, it is preferable because the height of the recording apparatus 1 can be kept low. On the other hand, when the type of the recording medium is a so-called strong firm (strong bending rigidity) material, it is preferable to keep the vertical posture in order to prevent deformation after ejection.
In the above-described embodiment, the opening / closing lid 21 is configured to open downward, but the upper opening of the opening / closing lid 21 may be opened. When the opening / closing lid 21 is opened upward, it is not necessary to drive the roller 34 when the paper 10 is discharged, so that the time required for discharging can be shortened. In this case, the user may pull out the sheet 10 held by the holding unit 22.

Embodiment 2
FIGS. 4A and 4B are schematic configuration diagrams when another form of the discharge mechanism 20 is viewed in a side cross-section.
In the above-described embodiment, the mode in which the paper 10 on which printing has been completed is held by the holding unit 22 and the opening / closing lid 21 is opened for each sheet to discharge the paper 10 has been described. However, the discharge mechanism according to the present embodiment 20 is different in that a plurality of sheets 10 can be accommodated.

Hereinafter, the configuration of the discharge mechanism 20 according to another embodiment will be described. In addition, the same code | symbol is used about the same structure as the above-mentioned embodiment, The description is abbreviate | omitted.
The discharge mechanism 20 according to another embodiment includes a holding unit 40. The holding means 40 is integrated with the opening / closing lid 21 by fixing a rectangular plate 35 having a size substantially equal to the area of the sheet 10 to be conveyed to the opening / closing lid 21. The holding means 40 is a box shape having an upper and lower opening having a side plate 36 rising in a right angle direction from a side portion of the rectangular plate 35, and a rectangular plate 37 opposed to the rectangular plate 35 and connected between the side plates 36; 36. A plurality of sheets 10 can be held between the rectangular plates 35;
Further, as shown in FIG. 4A, in the state in which the open / close lid 21 is closed, the interval between the rectangular plates 35; 37 is substantially equal to the interval between the guide portions 18; Therefore, the sheet 10 that has passed through the outlet of the discharge mechanism guide passage 16 smoothly enters the holding unit 40.

The lower opening 40A of the holding means 40 configured in a box shape is opened and closed by an opening / closing bottom 38. The open / close bottom 38 is rotatably locked to the lower end portion of the rectangular plate 37 via a rotation shaft (not shown), and comes into contact with the guide portion 19 in a state where the open / close lid 21 closes the opening portion 2A. A part of the opening 40A is closed.

It is gradually pulled up in the vertical direction while being sandwiched between the two.

A paper pressing spring 44 is attached above the roller 39. The paper pressing spring 44 is locked through a locking hole formed on the surface of the rectangular plate 35, and is bent and provided with the direction of the rectangular plate 37 as a vertex. A plurality of paper pressing springs 44 are arranged in a direction orthogonal to the transport direction, and press the paper 10 uniformly along the digit direction.
By providing the paper pressing spring 44, the paper 10 that has passed between the roller 39 and the tip of the opening / closing bottom 38 is positioned in the bending direction of the paper pressing spring 44, that is, in the direction of the rectangular plate 37. Pulled vertically. When the pulling-up operation by the roller 39 that continues for a predetermined period is completed, the paper 10 is held in a state in which the paper 10 is taken into the closed opening / closing bottom 38, the side plate 36, and the rectangular plates 35;

  As described above, when the holding unit 40 completes the holding of one sheet of paper 10, the succeeding sheets 10 on which printing has been completed are sequentially conveyed into the holding unit 40, and the holding unit 40 stores a plurality of sheets 10. To hold the paper 10. Further, at this time, the plurality of sheets 10 accommodated in the holding means 40 are in a state where the printing surface faces the upstream side, and the sheet 10 previously accommodated by the action of the sheet pressing spring 44 is positioned on the upstream side. It becomes a state.

  After the predetermined number of sheets 10 are stored in the holding means 40, the sheet 10 is discharged by opening the opening / closing lid 21. Since the opening operation of the opening / closing lid 21 is the same as in the above-described embodiment, the description thereof is omitted. However, when the opening / closing lid 21 is opened, the contact between the opening / closing bottom 38 and the guide portion 19 is released, and the opening / closing bottom 38 is accommodated. The plurality of sheets 10 are released by their own weight. Then, in a state where the open / close bottom 38 is opened, the plurality of stored sheets 10 are discharged so as to be ejected downward along the inclination of the open / close lid 21. Further, since the plurality of ejected sheets 10 are in the state in which the printing surface faces downward as in the above-described embodiment, and the plurality of sheets 10 correspond to the page order in the data, the sheets 10 are printed after printing is completed. It is possible to save the trouble of rearranging the order.

As described above, according to the recording apparatus 1 including the discharge mechanism 20 according to another embodiment, the holding unit 40 includes the opening / closing bottom 38 and the sheet pressing spring 44, thereby accommodating a plurality of sheets 10 to be sequentially conveyed therein. In comparison with the above-described embodiment, the discharge frequency of the paper 10 can be reduced, and the time required to complete the printing can be effectively shortened.
In addition, since the plurality of sheets 10 can be accommodated in the holding means 40, it is possible to obtain the same effect as the soundproofing effect by substantially increasing the thickness of the opening / closing lid 21, and to perform a printing operation with better silence. Can be done.

  As mentioned above, although this invention was demonstrated using embodiment, the technical scope of this invention is not limited to the range as described in the said embodiment. Various modifications or improvements can be added to the above embodiment.

  Although the recording apparatus 1 has been described as a liquid ejecting apparatus, the discharge mechanism in the present embodiment can be similarly applied to a recording apparatus such as a laser printer or a facsimile. In addition, the liquid ejecting apparatus only needs to have a recording head for ejecting liquid, and in a state where electrode materials and color materials employed in the manufacture of liquid crystal displays, EL displays, surface emitting displays, color filters, etc. are dispersed or dissolved. Also includes a spraying device. The recording medium is not particularly limited as long as it can be transported to the recording unit, such as not only so-called plain paper but also thermal paper, film, and the like.
