Description

  The present invention relates to a recording medium support device that is provided opposite to a recording head for recording on a recording medium and that defines a gap between the recording medium and the recording head by supporting the recording medium, and The present invention relates to a recording apparatus provided. The present invention also relates to a liquid ejecting apparatus.

Here, the liquid ejecting apparatus uses an ink jet recording head, and is not limited to a recording apparatus such as a printer, a copying machine, and a facsimile machine that discharges ink from the recording head to perform recording on a recording medium. And a device that ejects a liquid corresponding to the application from a liquid ejecting head corresponding to the ink jet recording head to an ejected medium corresponding to a recording medium, and adheres the liquid to the ejected medium. .
In addition to the recording head, as a liquid ejecting head, a color material ejecting head used for manufacturing a color filter such as a liquid crystal display, and an electrode material (conductive paste) used for forming an electrode such as an organic EL display or a surface emitting display (FED) Examples thereof include an ejection head, a bioorganic matter ejection head used for biochip production, and a sample ejection head as a precision pipette.

  An example of the recording apparatus or the liquid ejecting apparatus is an ink jet printer. An ink jet printer defines a gap between a recording head and a recording sheet by supporting the recording sheet from below at a position facing a recording head that ejects ink (liquid) onto a recording medium as a recording medium or an ejection medium. A support member (also called a paper guide or a platen) is provided.

  Here, on the surface of the support member that faces the recording head, a plurality of ribs that support the paper and that extend in the paper feed direction are provided at appropriate intervals in the paper width direction. This is to form a wavy state (so-called “cockling state”) having a constant amplitude on a recording sheet that swells by absorbing ink, thereby making the distance between the recording surface and the recording head as uniform as possible. is there.

  The rib may be provided so as to be divided into an upstream side and a downstream side. For example, in a printer configured to perform so-called marginless recording, which performs recording without margins at the end of the recording paper, a slot extending in the main scanning direction is formed so as to divide the rib. In addition, borderless recording is performed by ejecting ink to a region that deviates from the upper or lower end of the sheet in a state where the upper or lower end of the sheet is desired in the slot (see, for example, Patent Document 1). ).

  By the way, the ribs are arranged at intervals of about 30 to 70 mm in consideration of the cockling cycle of the recording paper, and are slightly inside from both sides of the recording paper in order to prevent sinking of both sides of the recording paper. It is arranged at the position. Further, when performing borderless recording on both sides of the recording paper, it is necessary to provide an ink discarding portion of about several mm (for example, about 3 mm) on both the inside and outside of both sides of the recording paper. The above ribs cannot be arranged.

  In this way, there is a restriction on the arrangement position of the ribs, but on the other hand, since there are recording papers of various sizes, when trying to satisfy the rib arrangement conditions for all the recording sheets of each size, The arrangement of the ribs becomes complicated. As a result, the ribs are arranged asymmetrically with respect to the center in the width direction for a certain size of recording paper or for all sizes of recording paper, but there is a frictional force between the recording paper and the ribs. For this reason, the frictional force acts asymmetrically with respect to the center in the width direction of the recording paper, and there is a possibility that the recording paper may have a skew tendency.

  Here, when the reference position in the direction perpendicular to the recording sheet conveyance direction is set to the center position of the recording sheet, the ribs are arranged symmetrically with respect to the center in the width direction of the recording sheet of each size. Although the above problems can be solved, for example, the L size photographic paper size and the 4 × 6 size photographic paper size have approximate width dimensions (3.5 inches in the former and 4 inches in the latter). In addition, it is impossible to satisfy the above-described rib arrangement condition for any of the recording sheets having similar sizes.

  Accordingly, the present invention has been made in view of such a situation, and an object of the present invention is to satisfy a rib arrangement condition even for a recording sheet having an approximate size, and the rib arrangement in the sheet width direction. An object of the present invention is to provide a paper support device that can prevent the occurrence of skew by being symmetrical with respect to the center position.

Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 to 3. Here, FIG. 1 is a side sectional view of an ink jet printer (hereinafter referred to as “printer”) 1 as an example of “recording apparatus” and “liquid ejecting apparatus” according to the present invention, and FIGS. FIG. 3 is a plan view of a paper support device 28 as a “recording medium support device” and “ejection medium support device”.
In the following, first, an outline of the printer 1 will be described with reference to FIG. In the following description, the left direction (front side of the printer) in FIG. 1 is referred to as “downstream side” of the paper transport path, and the right direction in FIG. 1 is referred to as “upstream side”.

  The printer 1 includes a feeding device 2 capable of setting a recording sheet (mainly cut sheet paper: hereinafter referred to as “sheet P”) as an example of “recording medium” and “ejection medium” in an inclined posture at the rear part, The paper P is fed from the feeding device 2 toward the conveying means 4 on the downstream side. The fed paper P is transported downstream (sub-scan feed) by the transport means 4 and recording is performed. The paper P on which recording has been performed by the recording head 27 is discharged to the front of the apparatus by the discharge means 5 on the downstream side.

Hereinafter, the components on the paper transport path will be described in more detail. The feeding device 2 includes a hopper 11, a feeding roller 12, a retard roller 13, a return lever 14, two edge guides 15, and other components not shown.
The hopper 11 is formed of a plate-like body, and is provided so as to be able to swing around an upper swinging fulcrum 11a. The pressure contact posture to be switched and the separation posture to be separated from the feeding roller 12 are switched. The feeding roller 12 has a substantially D shape when viewed from the side, and feeds the uppermost sheet P pressed by the arc portion to the downstream side.

  The retard roller 13 is provided so as to be able to press-contact with the arc portion of the feeding roller 12 and is provided with a predetermined rotational resistance (torque). If only a plurality of sheets of paper P exist between the feed roller 12 and the retard roller 13, the paper does not rotate. In this state, the paper P is prevented from being double fed. The return lever 14 is provided so as to be swingable when the paper P feeding path is viewed from the side. By swinging, the return lever 14 returns the succeeding and subsequent sheets P to the hopper 11.

  The edge guides 15 are provided on both sides of the paper P, and are provided on the hopper 11 so as to be slidable and displaceable in the paper width direction (the front and back sides in FIG. 1). By positioning, the position in the direction orthogonal to the feeding direction of the paper P is regulated. In this embodiment, since the paper P is fed based on the center reference, the two edge guides 15 are close to and away from each other with reference to the center position in the width direction of the paper P, and the displacement amount is equal. Displaced as

Next, a detecting means (not shown) for detecting the passage of the paper P is formed between the feeding device 2 and the transporting means 4, and a feeding posture of the paper P is formed and the paper P feeding roller 12 is formed. A guide roller 22 is provided to prevent the contact load to reduce the conveyance load.
The transport unit 4 includes a transport drive roller 23 that is rotationally driven by a motor (not shown), and a transport driven roller 24 that is driven to rotate while being in pressure contact with the transport drive roller 23. The transport driving roller 23 is provided with an adhesion layer in which wear-resistant particles are dispersed almost uniformly on the outer peripheral surface of a metal shaft extending in the paper width direction (main scanning direction), and the transport driven roller 24 has an outer peripheral surface of an elastomer. A plurality of such low friction materials are provided in the axial direction of the transport drive roller 23.

  The transport driven roller 24 is pivotally supported at the downstream end portion of the paper guide top 24 so as to be freely rotatable. The paper guide top 24 is supported by the shaft 24a being pivotally supported by the main frame 7 so that the paper transport path is viewed from the side. The coil driven spring 24 is urged by the coil spring 25 in a direction in which the conveyance driven roller 24 is pressed against the conveyance driving roller 23.

The paper P that has reached the transport means 4 is sub-scanned and sent downstream by the transport drive roller 23 rotating while being nipped by the transport drive roller 23 and the transport driven roller 24.
A recording head 27 that discharges ink (liquid) toward the paper P and a paper support device 28 that is disposed to face the recording head 27 are provided on the downstream side of the transport unit 4. The recording head 27 is provided at the bottom of the carriage 25. The carriage 25 is driven to reciprocate in the main scanning direction by a drive motor (not shown) while being guided by a carriage guide shaft 26 extending in the main scanning direction. The carriage 25 is mounted with independent ink cartridges (not shown) for each of a plurality of colors, and supplies ink to the recording head 27.

  The paper support device 28 that regulates the distance between the paper P and the recording head 27 includes fixing ribs 36a to 36c and 37a to 37c on a base 28 formed of a resin material (see FIG. 2), and is displaced in the paper width direction. The movable slide members 29 and 30 are provided with movable ribs 38a to 38c and 39a to 39c (see FIG. 2). In the recesses 41 and 42 in a side sectional view, ink that has been removed from the edge of the paper is discarded when performing so-called borderless recording in which recording is performed without margins on the upper and lower ends of the paper P.

  Specifically, for example, the borderless recording is performed on the upper end of the paper P by ejecting ink to an area outside the upper end of the paper P with the upper end of the paper P positioned above the recess 42. Similarly, borderless recording is performed on the lower end of the paper P by discharging ink to an area outside the lower end of the paper P with the lower end of the paper P positioned above the groove 41.

  When performing borderless recording on the upper end of the paper P, the upper end of the paper P does not reach the discharge means 5, and therefore the paper P receives a feeding force only from the transport means 4 (first feed mode). . Next, when the upper end of the paper P reaches the discharge means 5, the paper P receives feed force from both the transport means 4 and the discharge means 5 (second feed mode). When the lower end of the paper P is removed from the conveying means 4, the paper P receives a feeding force only from the discharging means 5 (third feeding mode).

  Subsequently, an auxiliary roller 47 and a discharge unit 5 are provided on the downstream side of the recording head 27. The auxiliary roller 47 is provided on the paper conveyance path from the area where the recording head 27 and the paper support device 28 face each other to the discharge unit 5 so as to be driven and rotated in contact with the recording surface of the paper P. The function of preventing the lifting from the support device 28 and maintaining the distance between the paper P and the recording head 27 constant is achieved.

  The discharge means 5 includes a discharge drive roller 45 that is rotationally driven by a motor (not shown), and a discharge driven roller 46 that is driven to rotate in contact with the discharge drive roller 45. The paper P on which recording has been performed by the recording head 27 is rotated toward the front of the apparatus (not shown in the figure) by rotating the discharge drive roller 45 while being nipped by the discharge drive roller 45 and the discharge driven roller 46. Discharged.

  Note that the sheet P is bent downward between the transport unit 4 and the discharge unit 5, and this also prevents the sheet P from being lifted up. That is, the nip point between the transport driving roller 23 and the transport driven roller 24 is set slightly downstream with respect to the paper transport direction, so that the paper feed direction by the transport means 4 is directed toward the paper support device 28. It has become. Accordingly, the paper P is thereby transported by the transport means 4 while being pressed against the paper support device 28 and is prevented from being lifted from the paper support device 28. For this reason, the paper P receives a transport load from each rib provided in the paper transport device 28.

The above is the general configuration of the printer 1, and the paper support device 28 will be described in detail below.
The paper support device 28 includes a plurality of ribs extending in the paper transport direction (vertical direction in FIGS. 3 and 4) at appropriate intervals in the paper width direction (horizontal direction in FIGS. 3 and 4). As described above, the fixed ribs 36a to 36c and 37a to 37c and the movable ribs 38a to 38c and 39a to 39c are configured.

  As described above, the printer 1 according to the present embodiment is center reference paper feed, that is, the reference position in the direction orthogonal to the paper transport direction (the left-right direction in FIGS. 3 and 4) when the paper P is transported is the paper P. The line is set at the center position in the width direction, and the line indicated by reference numeral c in FIGS. 3 and 4 indicates the reference position. Accordingly, regardless of the paper size, the papers P of all sizes are transported in a state where the center position in the width direction is aligned with the reference position c.

  The fixing ribs 36a, 36b, and 36c are disposed at the reference position c, and support the center position in the width direction of the paper P of all sizes from below. The fixed ribs 37a to 37c are formed on both sides of the fixed ribs 36a to 36c, and are formed in a state where the central portion is divided so as to allow displacement of the movable ribs 38a, 38b, and 38c in the paper width direction. (Fig. 1).

  Slide members 29 and 30 having a substantially L shape in plan view are provided below the base 28a where the fixed ribs 36a to 36c and 37a to 37c are formed. The movable ribs 38a to 38c and 39a to 39c are These are formed by the tops of the portions formed in a comb shape so as to protrude from the slide members 29 and 30 toward the base 28a.

  Racks 29a and 30a are formed on the arm portions of the slide members 29 and 30 extending in the paper width direction, respectively, and a pinion gear 34 driven by a drive motor 31 (FIG. 1) meshes with the racks 29a and 30a. is doing. Therefore, when the pinion gear 34 is rotated by receiving the power of the drive motor 31, the slide members 29 and 30 are slidably displaced by the same amount so as to be close to or separated from each other along the paper width direction, and thereby the movable rib 38a. -38c and 39a-39c are displaced in the paper width direction.

  In FIG. 2, the sheet indicated by reference numeral P1 is an A4 size sheet (in the case where the longitudinal direction is the transport direction) as an example. As shown in the figure, the movable ribs 38a to 38c and 39a to 39c are displaced, so that the movable ribs 39a to 39c are arranged slightly inward from both side edges of the paper P1, and both side edges (both sides) of the paper P1 are disposed. ) Is prevented from sinking. The sheet P1 is further supported from below by inner movable ribs 38a to 38c and fixed ribs 36a to 36c and 37a to 37c.

  Here, the intervals between the ribs are substantially constant in the paper width direction, and the ribs are arranged symmetrically with respect to the reference position (reference line) c. Accordingly, a regular cock ring is formed on the paper P1, thereby preventing the gap between the recording head 27 and the paper P1 from becoming extremely non-uniform and conveying from each rib. Since the load is symmetric with respect to the reference position c, the load that the sheet P1 receives from each rib is symmetric in the sheet width direction, thereby preventing the occurrence of skew.

  Of the movable ribs 39a to 39c provided farthest from the central fixed ribs 36a to 36c, the ink capturing section 40 is disposed outside the movable rib 39b located at the center in the paper transport direction. The side edge of the paper P1 is positioned above the ink catching section 40 as shown in the figure. In this state, the ink is ejected to the side edge of the paper P1 and the area off the side edge, thereby making the paper Borderless recording is performed on the side edge of P1, and ink is dumped into the ink capturing section 40. The abandoned ink is captured by the ink capturing unit 40, and the generation of ink mist is prevented. The ink capturing unit 40 is composed of an ink absorbing material (for example, a sponge material) so that the ejected ink is captured.

  In this embodiment, the interval between the fixing ribs 36a to 36c and the adjacent fixing ribs 37a to 37c (the distance in the paper width direction) in FIG. The distance between the ribs 37a to 37c and the movable ribs 38a to 38c is about 32 mm, the distance between the movable ribs 38a to 38c and the movable ribs 39a to 39c is about 35 mm, and the distance between the movable ribs 39a to 39c and the sheet edge is about 3 mm. Become.

  Next, the sheet indicated by reference numeral P2 in FIG. 3 is an L-size photographic sheet (when the longitudinal direction is the transport direction). As shown in the drawing, by moving the slide members 29 and 30 from the rib arrangement suitable for the A4 size shown in FIG. 2, the movable ribs 39a to 39c are slightly inward from both sides of the paper in the same manner as the paper P1. Can be arranged, and the ribs can be arranged symmetrically with respect to the reference position (reference line) c, and the occurrence of skew can be prevented.

  As described above, the movable ribs 38a to 38c and 39a to 39c are displaced, so that the sheets are supported on the inner sides of both side edges with respect to all of a plurality of types of sheets having different sizes, with respect to the center position in the width direction. The ribs can be arranged symmetrically, and the ribs can be arranged at appropriate positions by displacing the ribs even with respect to the paper having a similar size. At the same time, the ribs can be arranged symmetrically with respect to the central position in the paper width direction regardless of the paper size, and the occurrence of skew can be prevented.

  In this embodiment, the distance between the fixed ribs 36a to 36c and the adjacent movable ribs 38a to 38c (distance in the paper width direction) is about 6 mm in FIG. The distance between the movable ribs 38a to 38c and the fixed ribs 37a to 37c is about 28 mm, the distance between the fixed ribs 37a to 37c and the movable ribs 39a to 39c is about 6 mm, and the distance between the movable ribs 39a to 39c and the sheet edge is about 3 mm. It becomes.

  The displacement operation of the movable ribs 38a to 38c and 39a to 39c as described above, that is, the displacement operation of the slide members 29 and 30 is executed by the control unit 6 (FIG. 1). The control unit 6 drives and controls the drive motor 31 based on information from the printer driver, and positions the slide members 29 and 30 at appropriate positions. That is, the movable ribs 38a to 38c and 39a to 39c are automatically and reliably positioned at appropriate positions according to the paper size information. In order to accurately grasp the position of the slide members 29 and 30 in the paper width direction, a linear scale may be provided on the slide member 29 or 30 and a sensor for detecting the linear scale may be disposed.

  In the embodiment described above, the slide members 29 and 30, that is, the movable ribs 38a to 38c and 39a to 39c are configured to be displaced by the power of the motor. However, the present invention is not limited to this, and for example, the edge guide 15 (FIG. 1).
