Description

  The present invention relates to a recording apparatus that conveys and records a recording medium and a liquid ejecting apparatus.

  Some ink jet printers that are one of recording apparatuses can perform recording on roll paper that is one of media. In such an ink jet printer, the roll paper immediately below the recording head may float due to the curl of the roll paper, and the roll paper may come into contact with the recording head and become contaminated. Therefore, the paper guide surface of the paper guide member arranged on the downstream side of the platen that faces the recording head is lowered below the platen surface to escape the leading edge of the roll paper, preventing the roll paper from lifting directly below the recording head. An ink jet printer has been proposed (see Patent Document 1).

JP 2000-158733 A

  In the ink jet printer described above, when the leading edge of the roll paper hangs down from the platen surface to the paper guiding surface, the portion close to the leading edge of the rolled paper comes into contact with the corner of the platen surface and the paper guiding surface. Here, when the roll paper is stiff, the roll paper immediately below the recording head will be lifted with a portion near the tip of the roll paper as a fulcrum, and the roll paper will come into contact with the recording head and become contaminated. There is a fear.

  The present invention has been made in view of the various problems as described above, and an object of the present invention is to completely prevent lifting in the middle of conveyance with respect to various recording media to prevent rubbing with the recording head. Another object of the present invention is to provide a recording apparatus and a liquid ejecting apparatus that can perform the above operation.

  To achieve the above object, in the recording apparatus for conveying / recording the recording medium of the present invention, a first guide member having a first guide surface facing the recording head and guiding the conveyance of the recording medium, A second guide member having a second guide surface disposed downstream of the first guide member for guiding the transport of the recording medium, wherein the second guide surface is the first guide member. A step portion is provided on a third guide surface that is lower than the first guide surface and connects the two guide surfaces. As a result, when the leading end of the recording medium hangs down from the first guide surface, it is supported by the third guide surface, so that a force in the direction opposite to the lifting direction is applied to the recording medium. It is possible to prevent the recording medium from rising and to prevent rubbing with the recording head.

  Further, the height of the stepped portion is set based on the degree of curvature of the recording medium. Thereby, it is possible to reliably prevent the recording medium from floating. Further, the step is characterized in that the first inclined surface, the flat surface, and the second inclined surface are formed in a continuous shape. As a result, when the leading end of the recording medium hangs down from the first guide surface, the recording medium is supported by the flat surface by sliding on the first inclined surface. Therefore, the recording medium has a force opposite to the lifting direction. As a result, the recording medium can be prevented from being lifted. Furthermore, when the leading end of the recording medium hangs down from the flat surface, the second inclined surface slides, and thereafter, the recording medium becomes flat due to the weight of the recording medium, and the medium can be prevented from rising. In addition, a suction unit that sucks the medium is provided on at least the first guide surface and the third guide surface. Thereby, it is possible to completely prevent the recording medium from being lifted.

  In order to achieve the above object, a liquid ejecting apparatus for ejecting a liquid onto a medium to be ejected according to the present invention includes the above-described medium conveying apparatuses. Thus, a liquid ejecting apparatus that exhibits the above-described actions can be provided.

The operation panel 160 is provided with a liquid crystal screen and various buttons so that the user can operate the buttons while checking the liquid crystal screen.

  FIG. 3 is a side view showing details of the transport unit 200. The transport unit 200 includes a flat paper feed guide 211 disposed from the paper feed unit 110 to the recording unit 120, a contact / separable paper feed roller 212 and driven roller 213, and a recording mounted on the carriage 122. A platen (first guide member) 214 which is a flat characteristic part of the present invention disposed opposite to the head 121, and a paper which is a characteristic part of the present invention disposed on the downstream side of conveyance immediately below the platen 214. A guide (second guide member) 215, a platen 214, and a paper suction unit 216 that sucks roll paper on the paper guide 215 are provided. Note that a cutter 129 for cutting the roll paper that has been recorded is attached to the carriage 122.

  The paper feed roller 212 is formed as one long roller, and the peripheral surface portion slightly larger than the maximum recordable paper width is coated with ceramic powder or the like. Thereby, since the slip at the time of paper feeding can be prevented, roll paper can be sent out with high precision. Although not shown in the drawing, both ends of the paper feed roller 212 are axially supported by the side frame via bearings, and are driven to rotate forward and backward by a driving force transmitted from the paper feed motor via a pulley and a belt. It has become.

  The driven roller 213 is formed as a plurality of short rollers, and is pivotally supported by a plurality of driven roller support members 213 a arranged in parallel in the axial direction above the paper feed roller 212. The driven roller 213 is pressed against the paper feed roller 212 by a biasing member 213b such as a spring attached to the driven roller support member 213a, and rotates forward and backward following the forward / reverse rotation drive of the paper feed roller 212. It is supposed to be. Accordingly, the roll paper can be firmly pressed from both sides and sent out, so that highly accurate recording can be performed.

  The platen 214 is formed in the shape of a rectangular flat plate having a length slightly larger than the maximum recordable paper width, and is disposed in the immediate vicinity of the conveyance downstream side of the paper feed roller 212. The paper guide 215 is also formed in the shape of a rectangular flat plate having a length slightly larger than the maximum recordable sheet width, and is disposed in the immediate vicinity of the transport downstream side of the platen 214. Details of the platen 214 and the paper guide 215 will be described later.

  The sheet suction unit 216 includes a pressure chamber 216a disposed below the platen 214 and the paper guide 215, and a fan (not shown) disposed below the pressure chamber 216a. The pressure chamber 216a is formed in a box shape in which a part of the upper surface is opened, a platen 214 and a paper guide 215 are attached to the open part of the upper surface, and a fan is attached via a pipe joint 216b attached to the bottom surface. It has been.

  The cutter 129 is arranged so as to be movable up and down in the vertical direction and movable in the main scanning direction so that the cutting edge faces downward. The cutter 129 is moved up and down by, for example, a solenoid and moved in the main scanning direction together with the carriage 122. Therefore, it is not necessary to separately provide a means for moving the cutter 129, so that space can be saved and cost can be reduced. The cutter 129 may be separated from the carriage 122 and moved in the main scanning direction by a unique belt mechanism, a motor, or the like.

  Here, as described in the background art, a portion immediately below the recording head 121 may be lifted due to the curl of the roll paper, and the roll paper may come into contact with the recording head 121 to be contaminated. . Therefore, the platen 214 and the paper guide 215 of the ink jet printer 100 according to the present embodiment are configured to prevent contamination due to the roll paper coming into contact with the recording head 121 and maintain a highly accurate recording state. First, the principle will be described with reference to the drawings.

  FIG. 4 is a view schematically showing the platen 214 and the paper guide 215 and their peripheral portions. As shown in FIG. 4A, the paper guide surface 215a of the paper guide 215 is conventionally disposed so as to be simply lower than the platen surface 214a of the platen 214, as indicated by the dotted line in the figure. For this reason, the roll paper P1 that hangs down from the platen surface 214a is supported at the nip point N, the upstream point U of the platen surface 214a, and the downstream point D. In this state, until the leading end of the roll paper P1 comes into contact with the paper guide surface 215a, the leading end portion of the roll paper P1 has a cantilever shape, so that it easily falls. Then, with the downstream point D of the platen surface 214a as a fulcrum, the portion of the roll paper P1 upstream from the downstream point D of the platen surface 214a, that is, the roll immediately below the recording head 121, is the amount that the leading end of the roll paper P1 has been lowered. The portion of the paper P1 is easily lifted.

  Therefore, in the present invention, as shown by the solid line in the figure, a step portion 217 is provided on the surface connecting the platen surface 214a and the paper guide surface 215a. That is, the step portion 217 includes an inclined surface 217a inclined downward from the flat platen surface 214a and a flat surface 217b continuing from the inclined surface 217a and connected to the paper guide surface 215a. For this reason, the leading edge of the roll paper P2 that hangs down from the platen surface 214a is lifted in contact with the flat surface 217b of the stepped portion 217, so that the roll paper P2 extends from the nip point N and the upstream point U to the downstream point D of the platen surface 214a. Will be supported by almost the entire surface. Therefore, the roll paper P2 immediately below the recording head 121 can be brought close to a flat surface while suppressing the lift.

  Here, the size of the curl differs depending on the type of roll paper, but the height and position of the step portion 217 are optimized by computer simulation and experiments so that the step portion 217 can accommodate these roll papers. I planned. In particular, among roll papers that cannot be sufficiently lifted by suction, it is important to use both roll paper with high rigidity and roll paper with low rigidity. In the case of roll paper with low rigidity, only the step 217 is used. Although it was possible to cope with the roll paper having high rigidity, it was not possible to cope with only the step portion 217.

  That is, as shown by the dotted line in FIG. 4B, the leading end of the rigid roll paper P3 protruding from the platen surface 214a does not hang down during the initial conveyance, and thus does not contact the flat surface 217b of the step portion 217. After being conveyed to some extent, it hangs down by its own weight and comes into contact with the flat surface 217b of the stepped portion 217. In this state, since the leading end portion of the roll paper P3 protrudes considerably from the platen surface 214a, the portion of the roll paper P3 immediately below the recording head 121 is likely to float with the vicinity of the upstream point U of the platen surface 214a as a fulcrum.

  Therefore, in the present invention, as shown by the solid line in the figure, a part of the stepped portion 217 provided on the surface connecting the platen surface 214a and the paper guide surface 215a is lowered on the downstream side. That is, the step portion 217 is inclined downwardly from the flat platen surface 214a and inclined downwardly to the paper guide surface 215a. The inclined surface 217a is inclined downward, the flat surface 217b is continuous from the inclined surface 217a, and the paper guide surface 215a is continuous from the flat surface 217b. The inclined surface 217c. For this reason, the leading edge of the roll paper P4 that hangs down from the platen surface 214a is likely to fall along the inclined surface 217c, so that the portion of the roll paper P4 immediately below the recording head 121 also falls as the leading edge of the roll paper P4 falls. And can be approached flat. Therefore, in this embodiment, the platen 214 and the paper guide 215 having the configuration shown in FIG. 4B are used, and will be described below with reference to the drawings.

  FIG. 5 is a perspective view showing details of the platen 214 and the paper guide 215. In the platen 214, a plurality of rectangular suction grooves 214b are arranged in a row at predetermined intervals in the main scanning direction of the platen surface (first guide surface) 214a. The suction groove 214b is formed in an inverted quadrangular frustum that is surrounded by inclined side walls on the four sides of the flat bottom surface. A plurality of suction holes 214d are formed through the bottom surface of each suction groove 214b and the top surface of the partition wall 214c of each suction groove 214b.

  In addition, a rectangular opening 214 e that communicates with the paper suction unit 160 is formed at the position of the platen surface 214 a corresponding to the side edge of the roll paper in the platen 214. An absorbing member (not shown) is fitted into the opening 214e, and the ink particles removed from the edge of the roll paper when the roll paper is recorded without a border are collected. The absorbent member only needs to have an appropriate air permeability. For example, a sponge, a water-absorbing polymer, a felt-like fibrous material, a nonwoven fabric, or the like is used.

  The paper guide 215 is formed with a cutter step 215b extending substantially in the center in the main scanning direction. The cutter step 215b is formed to have a size that allows the cutting edge of the cutter 129 protruding from the lower surface of the roll paper to enter so that the cutter 129 does not damage the paper guide 215 when cutting the roll paper in the width direction. Yes. As a result, the recorded portion and the unrecorded portion of the roll paper can be reliably separated. The paper guide 215 is formed as a paper guide surface (second guide surface) 215a on the conveyance downstream side with the cutter step 215b as a boundary, and an intermediate surface (paper surface 215a and platen surface 214a) on the conveyance upstream side. (Third guide surface) 217a.

  That is, the paper guide surface 215a is disposed lower than the platen surface 214a, and an intermediate surface 217a that connects these surfaces 215a and 214a and a step portion 217 is provided on a part of the platen surface 214a. The step portion 217 includes a platen surface (first inclined surface) 214a inclined downward on the downstream side of the conveyance of the flat platen surface 214a, and a flat intermediate surface (flat surface) following the inclined platen surface 214a. 217a and an intermediate surface (second inclined surface) 217a inclined downward from the flat intermediate surface 217a and connected to the paper guide surface 215a.

  Thus, when the leading edge of the roll paper hangs down from the flat platen surface 214a, the roll paper slides on the inclined platen surface 214a and is supported by the flat intermediate surface 217a. In particular, the roll paper can be prevented from being lifted immediately below the recording head 121. Furthermore, when the leading edge of the roll paper hangs down from the flat intermediate surface 217a, the roll intermediate paper 217a slides, and thereafter, the roll paper becomes flat due to the weight of the roll paper. In particular, the roll paper floats directly under the recording head 121. Can be prevented. Accordingly, since the paper posture is stable and the gap between the recording head 121 and the roll paper is reduced, the image quality can be further improved by bringing the recording head 121 closer to the roll paper.

  Note that the height of the stepped portion 217, that is, the height difference between the flat platen surface 214a and the flat intermediate surface 217a is set based on the degree of curvature of the roll paper. Thereby, it is possible to reliably prevent the roll paper from being lifted. The stepped portion 217 may be formed according to the type of roll paper. For example, the stepped portion 217 is configured by only the platen surface 214a inclined downward and the flat intermediate surface 217a without forming the intermediate surface 217a inclined downward. Alternatively, instead of the intermediate surface 217a inclined downward, the intermediate surface 217a inclined upward may be used, or a plurality of stepwise configurations may be adopted.

  Further, a plurality of rail-shaped ribs 215c and 215d are disposed on the intermediate surface 217a and the paper guide surface 215a. The ribs 215c and 215d are arranged in a row at predetermined intervals in the main scanning direction, and the ribs 215c and 215d are arranged in a straight line in the sub-scanning direction. A plurality of suction holes 215e and 215f are formed in the intermediate surface 217a and the paper guide surface 215a between the ribs 215c and 215d.

  In the configuration as described above, by rotating the fan of the sheet suction unit 216, air is sucked into the pressure chamber 216a from the suction holes 214d, 215e, and 215f formed in the platen 214 and the paper guide 215, and passes through the fan. Exhausted to the outside. Therefore, when roll paper is supplied to the upper surface of the platen 214 and the paper guide 215, negative pressure is generated on the lower surface side of the roll paper. Therefore, the roll paper is attracted to the upper surface of the platen 214 and the paper guide 215 to The paper posture can be stabilized by completely preventing the lifting, and the recording accuracy can be reliably maintained with high accuracy. As described above, the platen 214 and the paper guide 215 are provided with the step portions 217, and the paper posture can be stabilized to some extent. Therefore, it is necessary to improve the performance of the paper suction portion 216 more than necessary. No cost can be reduced.

  In such a configuration, when the ink jet printer 100 is used, first, the spindle 113 constituting the roll paper holder 111 is taken out from the paper supply unit 110 and inserted into the spindle 113 as shown in FIG. The roll paper presser 114 is pulled out from one end of the spindle 113. Then, as shown in FIG. 7, one end of the spindle 113 is inserted through one end of the shaft hole C of the roll paper R, and one end of the shaft hole C of the roll paper R is inserted into the spindle 113 as shown in FIG. The other roll paper presser 114 inserted and fixed on the other end side is fitted and brought into contact therewith. Subsequently, one roll paper presser 114 is inserted from one end of the spindle 113 and fitted into the other end of the shaft hole C of the roll paper R. Thereby, the roll paper R can be rotated together with the spindle 113.

  Next, as shown in FIG. 9, the both ends of the spindle 113 in which the roll paper R is inserted are lifted up to the paper feeding unit 110. Here, as shown in FIG. 10, a relatively shallow recess 115a for temporarily placing the end portion of the spindle 113 and the end portion of the spindle 113 are rotatably supported on the spindle receiver 115. The comparatively deep hollow 115b is arranged in parallel at the front and back. The recess 115a on the near side is provided for temporary placement because the operation of temporarily inserting the spindle 113 into which the heavy roll paper R is inserted into the regular recess 115b is difficult.

  Therefore, as shown in FIG. 10, both ends of the spindle 113 into which the roll paper R is inserted are temporarily placed in the temporary recesses 115a of the spindle receiver 115, and then, as shown in FIG. One end of the spindle 113 in which the R is inserted is hung on the regular recess 115b of the corresponding spindle receiver 114, and then the other end of the spindle 113 in which the roll paper R is inserted is the regular recess of the corresponding spindle receiver 115. 115b. As a result, the spindle 113 with the roll paper R inserted can be safely and easily set in the paper feeding unit 110.

  Next, as shown in FIG. 12, the leading edge of the roll paper R is drawn downward and passes through the transport path of the recording unit 120, and further passes through the transport path of the paper discharge unit 130 as shown in FIG. Then, as shown in FIG. 14, the roll paper R is rotated in the winding direction so that the leading end of the roll paper R is positioned at a marker M formed on the paper discharge guide 131, for example. Thereafter, the ink jet printer 100 is activated, and ink droplets are ejected while the recording head 121 is moved in the main scanning direction while feeding the roll paper R in the sub-scanning direction, thereby recording predetermined information on the roll paper R. .

  Any recording apparatus provided with a medium conveying apparatus can be applied to, for example, a facsimile apparatus and a copying apparatus. In addition to a recording apparatus, the meaning of a liquid ejecting apparatus that ejects a liquid corresponding to its use from a liquid ejecting head onto an ejected medium instead of ink and attaches the liquid to the ejected medium is, for example, a liquid crystal display Color material jet head used for manufacturing color filters, electrode material (conductive paste) jet head used for electrode formation for organic EL display and surface emitting display (FED), bio-organic jet head used for biochip manufacturing, precision pipette The present invention can also be applied to an apparatus equipped with a sample ejection head or the like.
