  The present invention relates to a liquid ejecting apparatus that ejects liquid supplied from a liquid cartridge or the like as droplets, and more specifically, a liquid ejecting apparatus configured to eject a thick target liquid such as cardboard and the like It relates to the supply tray used.

  Conventionally, an ink jet recording apparatus is widely known as one of liquid ejecting apparatuses. This ink jet recording apparatus performs recording by alternately repeating the operation of reciprocating the recording head in the main scanning direction and conveying a recording sheet as a recording material in the sub scanning direction by a predetermined conveyance amount. In such a recording apparatus, generally, a single sheet of recording paper such as plain paper stacked on a paper feed tray or the like disposed on the upstream side in the sub-scanning direction of a recording execution unit such as a recording head. An automatic paper feeder that automatically feeds paper one by one is provided. Similarly, the automatic paper feeding means, which is disposed upstream of the recording execution means in the sub-scanning direction and has a roll paper holder for supporting the roll-shaped roll paper, can feed the roll paper manually and execute recording. Some recording apparatuses have a paper feed path different from the paper feed path of the recording paper.

  Furthermore, assuming that recording can be performed on a CD-R or the like, the CD-R or the like is mounted on a dedicated tray, and the tray is manually fed from the downstream side in the sub-scanning direction of the recording execution means to execute recording. There is a recording apparatus having another possible paper feed path (for example, Patent Document 1 below).

  As shown in FIG. 11, the tray 71 is formed in a substantially rectangular plate shape by resin molding, and a fitting recess 72 for fitting the CD-R 70 is formed at the center of the surface. In a state where the CD-R 70 is fitted in the fitting recess 72, paper is manually fed to the recording apparatus and recording is performed on the surface of the CD-R 70.

  FIG. 12 shows a state in which printing is performed by manually feeding the tray 71 loaded with the CD-R 70 to the recording apparatus. The recording apparatus is provided with a guide member 73 that guides the tray 71 that is fitted to the left and right of the manually fed tray 71 and conveyed in the sub-scanning direction. The tray 71 is configured such that the surface of the CD-R 70 and the surface of the tray 71 are flush with each other in a state where the CD-R 70 is mounted in the fitting recess 72.

In this state, the recording head 74 is reciprocated in the main scanning direction while transporting the tray 71 in the sub-scanning direction, and ink droplets are ejected from the nozzles on the lower surface of the recording head 74, thereby printing on the surface of the CD-R 70. Done. In this case, the distance D ₁ between the recording head 74 and the surface of the CD-R 70 in a state where the CD-R 70 is inserted into the tray 71 having a predetermined thickness that is just fitted to the guide member 73 so that the surface is flush. Is set to an appropriate distance, and recording can be performed by ejecting ink when the recording head 74 reciprocates in both directions.

In the above recording apparatus, there is a case where it is desired to feed thick paper to the paper feed path of the tray 71 and print on the thick paper. In this case, as shown in FIG. 13, printing is performed by manually feeding the thick paper 75 to the guide member 73 that is the paper feed path of the tray 71. There are various types of cardboard 75, the thickness is various, and most of the cardboard 75 is different in thickness from the tray 71. A plate having a thickness greater than that of the tray 71 does not enter the guide member 73 and cannot be fed, but a sheet thinner than the tray 71 entering the guide member 73 can be manually fed once. When feeding such cardboard 75, becomes the cardboard 75 is positioned below in the guide member 73, the distance D ₂ between the recording head 74 and the cardboard 75 surface, the recorded CD-R70 in the tray 71 it becomes larger than the distance D ₁ of the case. Thus, contamination when the distance D ₂ between the recording head 74 and the cardboard 75 surface becomes large, the inside of the apparatus is increasing ink droplets floating in a mist without reaching up to the surface of the cardboard 75 after being ejected from the nozzle Will be allowed to. Even if the ink droplets land on the surface of the cardboard 75, the landing position shifts greatly and the image quality is degraded. Further, the deviation of the landing position between the printing in the forward path and the printing in the backward path when the recording head 74 reciprocates increases, and the recording is performed by ejecting ink when the recording head 74 moves bidirectionally. There is a problem that printing cannot be performed and it takes twice or more printing time.

  The present invention has been made in view of such circumstances, and an object thereof is to provide a liquid ejecting apparatus capable of ejecting liquid onto an ejecting target having different thicknesses such as cardboard and a supply tray used therefor.

  In order to solve the above-described problems, a liquid ejecting apparatus according to the present invention includes a liquid ejecting head that is mounted on a carriage that reciprocates in the main scanning direction and ejects liquid from a nozzle surface, and the liquid in a state where a material to be ejected is attached.

The recording control unit 1 performs recording control of the recording device 50.

  Next, the supply tray 10 will be described in detail.

  FIG. 3 is a perspective view showing the supply tray 10. The supply tray 10 includes a tray body 15 that is rectangular and has a substantially plate shape as a whole, two holding members 16 provided on both sides in the width direction corresponding to the main scanning direction X of the tray body 15, and a tray body. 15 and a spring member 17 as urging means for urging the cardboard 11 attached to 15 toward the nozzle surface 62a.

  The tray main body 15 has a substantially rectangular shape set to a width dimension guided by the guide member 12 of the recording apparatus 50, and is formed of a synthetic resin or the like in this example. Holding members 16 are provided at two front and rear positions corresponding to the sub-scanning direction Y of one side edge (right side in FIG. 3) of the tray main body 15 and two front and rear positions of the other side edge facing the one side edge. It has been. The front and rear holding members 16 are arranged to face each other.

  The holding member 16, in this example, a metal plate such as stainless steel is formed by being bent in a substantially U shape, and the lower horizontal piece 16 a of the two U-shaped horizontal pieces is bonded to the bottom surface of the tray body 15 with an adhesive or the like. The U-shaped vertical piece 16b contacts the side surface of the tray body 15, and the U-shaped upper horizontal piece 16c faces the surface of the tray body 15 on the nozzle surface 62a side with a predetermined interval. It has become.

  In the vicinity of the holding member 16, the spring member 17 faces the upper horizontal piece 16 c of the tray body 15 at a location where the U-shaped upper horizontal piece 16 c of the holding member 16 faces the surface of the tray body 15. Attached to the part.

  4 and 5 are diagrams for explaining the details of the attachment state of the holding member 16 and the spring member 17. As described above, the holding member 16 is formed in a substantially U shape by a metal plate such as stainless steel. On the other hand, a side surface notch portion 18 corresponding to the plate thickness of the holding member 16 is formed on the side surface of the tray body 15, and a bottom surface notch portion 19 corresponding to the plate thickness of the holding member 16 is also formed on the bottom surface of the tray body 15. Has been. The holding member 16 is inserted into the tray main body 15 in a state where the U-shaped lower horizontal piece 16a is fitted into the bottom cutout portion 19 and the U-shaped vertical piece 16b is fitted into the side cutout portion 18. It is fixed with an adhesive or the like.

  In this state, the side surface of the supply tray 10 is flush with the side surface of the tray body 15 and the vertical piece 16 b of the holding member 16, and the bottom surface of the supply tray 10 is the bottom surface of the tray body 15 and the lower part of the holding member 16. The horizontal piece 16a is configured to be flush with each other. As described above, since the protrusions are not formed on the side surface and the bottom surface of the supply tray 10 and the holding member 16 and the tray main body 15 are flush with each other, the supply tray 10 is supplied to the guide member 12 and conveyed. When guiding, the holding member 16 is prevented from being caught and hindering conveyance.

  In this example, the spring member 17 is formed by bending an elastic member such as a synthetic resin. The spring member 17 is attached to the attachment portion of the holding member 16. That is, the mounting hole 20 is formed on the surface of the tray main body 15 facing the upper horizontal piece 16c of the attached holding member 16, and the spring member 17 is fixed to the mounting hole 20 with an adhesive or the like. As a result, the spring member 17 is disposed on the front surface side of the tray body 15 so as to face the upper horizontal piece 16c of the holding member 16 with a predetermined interval.

  Then, with the thick paper 11 inserted between the upper surface of the tray body 15 and the upper horizontal piece 16 c of the holding member 16, the thick paper 11 to which the spring member 17 is attached comes into contact with the upper horizontal piece 16 c of the holding member 16. It has become.

  Further, the holding member 16 is prevented from being displaced due to friction with the cardboard 11 that contacts the surface of the upper horizontal piece 16c facing the spring member 17, that is, the part facing the recording surface of the cardboard 11. A slip prevention sheet 21 is attached. The slip prevention sheet 21 is in contact with the recording surface of the thick paper 11 when the thick paper 11 is attached to prevent the slip of the thick paper 11.

  As shown in FIG. 6, the holding member 16 provided on one side edge (the right side in the figure and the home position side of the recording apparatus 50) side of the tray body 15 is directly attached to the tray body 15, The holding member 16 on the other side edge (the left side in the drawing) of the main body 15 is attached to a slide member 24 that can change the distance from the one side edge.

  That is, on the other side (the left side in the drawing) of the tray main body 15, a slit portion 22 extending from the end edge toward the opposite end edge is cut out. A fitting groove 23 extending in the longitudinal direction of the slit is formed on the inner surface facing the slit portion 22, and fitting ridges 25 fitted into the fitting groove 23 are formed on both side surfaces of the slide member 24. Is formed. The slide member 24 is slidably attached to the slit portion 22 by fitting the fitting protrusion 25 of the slide member 24 into the fitting groove 23 of the slit portion 22.

  The attachment state of the holding member 16 and the spring member 17 to the slide member 24 is the same as the state described in FIGS.

  Thus, when a recording medium such as thick paper 11 having a width smaller than that of the tray main body 15 is attached, one end of the thick paper 11 is brought into contact with the holding member 16 on the fixed side, and the slide member 24 is moved to the fixed side. The other end of the cardboard 11 is brought into contact with the holding member 16 on the sliding side, so that it can be mounted without any problem.

  With such a configuration, as shown in FIG. 7, the supply tray 10 has the spring member 11 inserted with the cardboard 11 inserted between the upper surface of the tray body 15 and the upper horizontal piece 16 c of the holding member 16. 17 biases the cardboard 11 toward the nozzle surface, and the cardboard 11 biased toward the nozzle surface has a predetermined gap 26 between the upper surface of the tray main body 15 and an upper horizontal piece of the holding member 16. It abuts on 16c and is held at a predetermined height position t. This height t is the distance from the bottom surface of the tray body 15 to the recording surface of the thick paper 11, and this distance is a fixed dimension, that is, when the CD-R 70 is mounted on the CD-R 70 tray 71 shown in FIG. By matching the height dimension from the bottom surface of the tray 71 to the recording surface of the CD-R 70, the distance between the recording surface of the cardboard 11 and the nozzle surface 62a of the recording head 62 can be kept constant. .

  Next, an operation of supplying the supply tray 10 to the recording device 50 and performing printing recording will be described.

  FIG. 8 shows the recording apparatus 50 in a state where the first release means is in the release state and the supply tray 10 is inserted from the third paper feed path C. FIG. 9 shows a state in which the first release means is brought into a non-release state after the supply tray 10 is inserted from the third paper feed path C.

  Since the conveyance driven roller 54 is urged by the conveyance driving roller 53 and the paper discharge driven roller 56 is urged by the paper discharge driving roller 55, the conveyance driven roller 54 is urged between the conveyance driven roller 54 and the conveyance driving roller 53 and discharged. There is no gap between the paper driven roller 56 and the paper discharge drive roller 55. When the supply tray 10 is forcibly inserted there, a holder (not shown), a biasing means (not shown), etc., which pivotally support the conveyance driven roller 54 and the discharge driven roller 56 so as to be driven to rotate, are provided. There is a risk of damage.

  Further, when the lever portion 63a of the paper detector 63 is configured to be rotatable only in the sub-scanning direction Y, the leading end of the supply tray 10 moves the lever portion 63a in the direction opposite to the sub-scanning direction Y. If it is pushed, the paper detector 63 may be broken. Further, when the leading end of the supply tray 10 hits the recording head 62, the head surface of the recording head 62 is damaged, or the head surface of the recording head 62 adjusted so as to have a specified interval and the recording surface of the recording material. There is a possibility that the interval between them may be shifted.

  Therefore, before the supply tray 10 is inserted into the third paper feed path C, the release follower 54, the paper discharge driven roller 56, the carriage 61, and the paper detector 63 are released in the direction indicated by symbol E by the release means. . Next, in this state, the supply tray 10 is inserted into the third paper feed path C until the leading end reaches a predetermined position upstream in the sub-scanning direction Y from the paper detector 63 (FIG. 8).

  At this time, first, as shown in FIGS. 3 and 7, recording paper such as thick paper 11 is mounted on the supply tray 10. In this state, as described above, the spring member 17 urges the cardboard 11 toward the nozzle surface, and the cardboard 11 abuts on the upper horizontal piece 16c of the holding member 16 and is held at a predetermined height position t. Is done. Then, when the supply tray 10 loaded with the thick paper 11 is supplied to the third paper feed path C, both sides are fitted into the guide member 12. Thereby, when the supply tray 10 is conveyed in the sub-scanning direction, the supply tray 10 is guided by the guide member 12 and accurately conveyed in the sub-scanning direction.

  When the first release means in the released state is returned to the non-released state, the conveyance driven roller 54, the paper discharge driven roller 56, the carriage 61, and the paper detector 63 are lowered in the direction indicated by the symbol F. The supply tray 10 is sandwiched between the transport drive roller 53 and the transport driven roller 54 and between the paper discharge drive roller 55 and the paper discharge driven roller 56.

At this time, as shown in FIG. 10, since the height of the recording surface of the thick paper 11 attached to the supply tray 10 is set to a predetermined height, the recording surface of the thick paper 11 and the recording head 62 are set. the distance D ₁ of the nozzle surface 62a can be defined intervals of the lever portion 63a of the paper detector 63, and a state of being rotated in the direction indicated by being pressed by the feed tray 10 by the arrow sign D (FIG. 9).

  In this state, the supply tray 10 detected as a recording material by the paper detector 63 is detected by the paper detector 63 after the release operation of the first release means. Then, it is determined that the recording material is fed from the third paper feed path C. In the present embodiment, since the recording material fed from the third paper feeding path C is only a material having a thickness such as the supply tray 10, the recording material is a recording control unit. 1, the supply tray 10 is determined.

  Note that the recording material detected by the paper detector 63 when the predetermined time has elapsed after the supply tray 10 is detected by the paper detector 63 after the release operation of the first release means is the third supply. It is preferable to determine that the recording material is fed from the paper path C because it is possible to prevent erroneous detection due to instantaneous detection by the paper detector 63. In the present embodiment, the predetermined recording material is used. Is set to about 2 seconds.

  Then, the recording control unit 1 executes recording control corresponding to the supply tray 10 on the supplied supply tray 10. When the supply tray 10 after paper feeding is pulled out by hand, the sensor 64 is in a state where the supply tray 10 is not detected. In such a state, since the recording cannot be executed as it is, the recording control unit 1 outputs an error message to notify that the supply tray 10 is not normally fed.

  In this way, after supplying the supply tray 10, the recording head 62 is reciprocated by the carriage 61, and the supply tray 10 is intermittently conveyed in the sub-scanning direction Y, and the nozzles on the nozzle surface 62 a of the recording head 62. By ejecting ink droplets from the openings, printing and recording on a recording medium such as the thick paper 11 is performed.

  When recording on the CD-R 70, the CD-R 70 tray 71 shown in FIG. 11 is inserted from the third paper feed path C, and the first release means is set to the non-release state. Recording is performed with the second release means in the release state. As described above, the recording is executed in a state where only the paper discharge driven roller 56 is released by the second release means, so that the paper discharge driven roller 56 is not in contact with the recording surface after the recording of the CD-R 70. Recording can be performed.

  With the above configuration, when using an injection target such as the cardboard 11, for example, the present invention transports the recording target 62 with the transport target while attaching the injection target to the supply tray 10 and guiding the guide member 12. Ink is ejected from the ink. At this time, the supply tray 10 is configured to eject the spring member 17 that urges the attached ejection target material such as cardboard 11 toward the nozzle surface 62a and the cardboard 11 that is urged toward the nozzle surface 62a. Since the holding member 16 that holds the target material at the predetermined height position t is provided, the injection target surface of the injection target is always at the predetermined height in the state of being conveyed by the conveying means while being guided by the guide member 12. At this position t, the distance from the nozzle surface 62a of the recording head 62 can always be kept constant. Even when an injection target having a different thickness or the like is attached to the supply tray 10, the injection target is biased toward the nozzle surface 62 a by the spring member 17 and is held at a predetermined height position t by the holding member 16. Retained.

Thus, even the thickness may vary from injection object, it is possible to keep the distance D ₁ of the from the nozzle surface 62a of the recording head 62 constant at all times. Therefore, the contamination in the apparatus due to ink droplets floating as mist without reaching the ejection target surface after being ejected from the nozzle is greatly reduced. Further, the displacement of the landing position of the ink droplet on the ejection target surface is not increased, and the image quality is ensured. Further, the deviation of the landing position between the ejection in the forward path and the ejection in the backward path when the recording head 62 reciprocates does not increase, and bidirectional printing that ejects ink when the recording head 62 moves bidirectionally is possible. Thus, the print recording time does not become long.

  The supply tray 10 is attached to the tray body 15 because the holding member 16 is provided at one side edge of the substantially plate-like tray body 15 and the other side edge opposite to the one side edge. At the one side edge portion and the other side edge opposite thereto, the injection target object is biased toward the nozzle surface 62a by the spring member 17 and is held at a predetermined height position t by the holding member 16. Retained. Therefore, the distance from the nozzle surface 62a of the recording head 62 can be always kept constant over substantially the entire ejection target surface of the ejection target such as the thick paper 11.

  In addition, since the holding member 16 on the other side edge is provided on the slide member 24 that can change the distance from the one side edge portion, the slide member 24 is slid even if it is an injection target having different dimensions. Thus, the recording surface can be held at a predetermined height position t at the one side edge and the other side edge opposite thereto.

  Further, since the spring member 17 is provided in the vicinity of the holding member 16, the biasing force of the spring member 17 directly acts on the holding member 16. Thus, the cardboard 11 is prevented from being bent or distorted, the flatness of the recording medium such as the cardboard 11 can be secured, and the distance from the nozzle surface 62a can be kept constant over the entire recording surface. .

  Further, since a deviation preventing sheet 21 for preventing deviation of the ejection target member such as the cardboard 11 is provided in a portion of the holding member 16 that faces the ejection target surface of the ejection target material, the cardboard is provided on the supply tray 10. 11 is attached and guided by the guide member 12 while being transported by the transport means, and when ejecting ink from the recording head 62, the ejection target such as cardboard on the supply tray 10 is prevented from shifting, and printing failure is prevented. Occurrence can be prevented and image quality can be secured.

  In the above description, the thick paper 11 has been described as an example of the recording medium of the ejection target. However, if it can be mounted on the above-described supply tray 10 and can be a target for liquid ejection such as printing, It is not limited and various injection objects can be applied.

  In the above description, the holding members 16 are provided on both sides in the sub-scanning direction Y. However, the present invention is not limited to this, and the holding members 16 may be provided on both sides in the main scanning direction X.

  The present invention can be applied to a liquid ejecting apparatus, and a typical example thereof is an ink jet recording apparatus provided with an ink jet recording head for image recording. As other liquid ejecting apparatuses, for example, an apparatus having a color material ejecting head used for manufacturing a color filter such as a liquid crystal display, an electrode material (conductive paste) used for forming an electrode such as an organic EL display, a surface emitting display (FED), etc. ) An apparatus equipped with an ejection head, an apparatus equipped with a bioorganic matter ejection head used for biochip manufacturing, an apparatus equipped with a sample ejection head as a precision pipette, and the like.
