Description

  The present invention relates to a recording apparatus, and more particularly to a recording apparatus capable of performing borderless recording on a recording medium in which a margin at an end edge of the recording medium is zero.

  Conventionally, an ink jet recording apparatus (hereinafter referred to as “printer”) is widely known as a recording apparatus that performs recording on a recording medium. In this printer, printing is performed by ejecting ink supplied from an ink cartridge onto a recording medium from a recording head. In recent years, in such a printer, as shown in, for example, Patent Document 1, a borderless printing (recording) technique has been proposed in which the margin at the edge of the recording medium is zero with respect to the recording medium. Yes.

  That is, in the printer shown in Patent Document 1, holes that can discard ink are formed on the upper surface of the platen that supports the recording medium at positions corresponding to edge portions in the width direction of the recording medium. During borderless printing, out of the ink ejected toward the edge in the width direction of the recording medium placed on the platen, the ink that protrudes outside the edge of the recording medium in the width direction, They were collected in these holes adjacent to the edge of the recording medium. Therefore, this printer can perform borderless printing on a recording medium without contaminating the upper surface of the platen.

JP 2003-285433 A

  By the way, in the printer shown in Patent Document 1, on the assumption that a plurality of types of recording media having different width dimensions are conveyed onto the platen, the upper surface of the platen has an edge in the width direction of various recording media. Holes are respectively formed at a plurality of corresponding positions. Therefore, when a recording medium having a large width dimension is conveyed onto the platen, a hole formed at a position corresponding to the edge of the recording medium having a small width dimension is placed on the platen. It will be located vertically below within the width of. Accordingly, in the case of a recording medium with particularly low rigidity, the recording medium placed on the platen is bent and deformed in such a way that it falls vertically downward and undulates in the vertical direction. However, there is a possibility that sufficient print quality cannot be ensured.

  The present invention has been made in view of such circumstances, and an object thereof is to provide a recording apparatus capable of ensuring sufficient recording quality for a plurality of recording media having different dimensions in the width direction. There is.

  In order to achieve the above object, the recording apparatus of the present invention comprises recording means capable of executing borderless recording in which a recording material is attached to the recording medium up to the edge in the width direction of the recording medium. A recording apparatus having a support surface capable of supporting the recording medium, and on the support surface, outside the edge portion of the recording medium in the width direction during the edgeless recording with respect to the recording medium A receiving portion for receiving the recording material discarded from the recording means at a position lower than the support surface, and the edge portions of the plurality of recording media having different dimensions in the width direction. In the support member at a position of at least one receiving portion among the supporting members formed at a plurality of corresponding positions, and the receiving portion at a position covered by the recording medium supported on the supporting surface. The above And changing means for changing the relative position in the height direction relative to the support surface of the facing surface that faces the medium, with a.

  According to the above configuration, the changing unit performs recording on the support member at the position of at least one receiving portion of the receiving portions on the support surface covered by the recording medium according to the widthwise dimension of the recording medium. When the relative position in the height direction with respect to the support surface of the facing surface facing the medium is changed, the recording medium undulates by dropping at the position of the receiving portion from the support surface even if the rigidity is low. The rate of bending deformation is reduced. Therefore, it is possible to improve the flatness of the recording medium in a state of being supported on the support surface of the support member. Therefore, sufficient recording quality can be ensured for a plurality of recording media having different dimensions in the width direction.

  In addition, the recording apparatus of the present invention further includes a detection unit that detects a dimension in the width direction of the recording medium supported on the support surface, and the change unit is based on a detection result of the detection unit, A receiving portion at a position covered by the recording medium is determined from the plurality of receiving portions formed on the support surface.

  According to the above configuration, the changing unit accurately determines the receiving portion at the position covered on the support surface of the support member by the recording medium based on the width-direction dimension of the recording medium detected by the detecting unit. be able to. Therefore, in order to improve the flatness of the recording medium, the support member changes the relative position in the height direction with respect to the support surface among the facing surfaces facing the recording medium at the position of the receiving portion on the support surface. Therefore, it is possible to more reliably improve the flatness of the recording medium in a state of being supported on the support surface.

  Further, in the recording apparatus of the present invention, the changing means is relative to the support surface in the height direction at the positions of all receiving portions at positions covered by the recording medium supported on the support surface. Change the position.

  According to the above configuration, the changing means changes the relative position in the height direction with respect to the support surface of the facing surface facing the recording medium in the support member at the positions of all receiving portions covered by the recording medium. As compared with the case where the relative position in the height direction with respect to the support surface is changed at the positions of some of the receiving portions covered by the recording medium, the recording medium having a low rigidity is supported. Since the rate of bending and deforming so as to wave and wave at the receiving portion from the surface is further reduced, the flatness of the recording medium supported on the support surface can be further improved.

In the recording apparatus of the present invention, the changing unit includes an opening / closing member provided for each of the receiving portions in order to individually open and close the openings of the plurality of receiving portions on the support surface.
According to the above configuration, the opening on the support surface of the receiving portion is opened and closed by the opening / closing member provided for each receiving portion, thereby facing the recording medium in the support member at the position of the receiving portion on the support surface. The relative position in the height direction of the opposing surface with respect to the support surface can be easily changed.

  In the recording apparatus of the present invention, the recording unit is a recording head that performs recording by ejecting a fluid as the recording material onto the recording medium supported on the support surface.

  According to the above configuration, during borderless recording on the recording medium, among the fluid as the recording material ejected from the recording head, the fluid discarded toward the outside in the width direction of the edge portion of the recording medium is used as the support member. It can collect | recover suitably by the receiving part formed on the support surface.

  Further, the recording apparatus of the present invention provides a recording head that discharges a recording material to a recording medium that is conveyed perpendicularly to the width direction, and a support height of the recording medium at a position facing the recording head. A support member, wherein the support member causes ink ejected from the recording head to be ejected from the support height at a position corresponding to the edge in the width direction of a recording medium of one size. The first state that can be received at a lower level and the second state that can support the recording medium at substantially the same level as the support height are configured to be mutually changeable.

  A recording head 22 as recording means is provided on the lower surface of the carriage 17. On the other hand, a plurality (two in this embodiment) of ink cartridges 23 and 24 for supplying recording material and ink as fluid to the recording head 22 are detachably mounted on the carriage 17. Each of these ink cartridges 23, 24 individually corresponds to a plurality of nozzle opening rows (not shown) formed on the lower surface of the recording head 22, and an ink flow path (not shown) formed in the recording head 22. The ink is individually supplied to the corresponding nozzle row via the).

  Furthermore, the left end portion in the frame 12, that is, the non-printing area where the recording paper P does not reach, is a home serving as a maintenance position for positioning the carriage 17 when the printer 11 is powered off or when the recording head 22 is maintained. A position HP is provided. A maintenance unit 25 that performs various maintenance operations is provided at a position below the home position HP so that the ejection of ink from the recording head 22 to the recording paper P is well maintained.

  An optical sensor 26 (paper width sensor) is provided on the lower surface of the carriage 17 as detection means for detecting reflected light from the recording paper P. As shown in FIG. 2, the printer 11 feeds the recording paper P to a position where the optical sensor 26 can detect it (the position of the recording paper P in FIG. 2), and then moves the carriage 17 from the home position HP. In the process of scanning toward the home position, the optical sensor 26 detects the paper edges P1 and P2 as the edge portions in the width direction (left-right direction) of the recording paper P.

Next, the configuration of the platen 14 of the present embodiment will be described with reference to FIGS.
As shown in FIGS. 3 and 4, the platen 14 of the present embodiment is a pair of substantially rectangular box-like platens arranged in parallel so as to extend in parallel in the left-right direction orthogonal to the conveyance direction of the recording paper P. It is composed of units 27 and 28. Each of the platen units 27 and 28 is made of a synthetic resin material, and has a hollow internal space 29 inside each.

  Of the platen units 27 and 28 constituting the platen 14, the first platen unit 27 arranged on the upstream side in the conveyance direction of the recording paper P has a support surface 27 a that supports the recording paper P formed on the upper surface thereof for recording. The head 22 is disposed so as to be positioned vertically below the reciprocating path of the head 22. Further, on the support surface 27a of the first platen unit 27, a plurality of (in the present embodiment, twelve) projecting ribs 30 extending along the short direction (front-rear direction) of the first platen unit 27 are provided. The first platen unit 27 is formed in parallel with a gap in the longitudinal direction (left-right direction).

  In addition, on the support surface 27 a of the first platen unit 27, a part of the intermediate region between the ribs 30 adjacent in the left-right direction has a plurality of receiving portions extending rearward from the front end surface of the first platen unit 27. The concave groove 31 is recessed. Specifically, in consideration of feeding a plurality of types of recording paper P having different width dimensions in the left-right direction from the paper feed tray 13 onto the support surface 27a of the first platen unit 27, the support surface 27a. A plurality of pairs (three pairs in the present embodiment) of the concave grooves 31 are located at positions corresponding to the paper edges P1 and P2 in the width direction of the various recording papers P at the center in the horizontal direction of the support surface 27a. Are formed in a symmetrical manner. Further, in each concave groove 31, when performing marginless printing (marginless recording) with zero margin in the width direction on the recording paper P, the outer side of the recording paper P in the width direction from the recording head 22 is executed. A waste ink absorbing material 32 for absorbing and collecting the waste ink that has passed through and disposed in each concave groove 31 is accommodated. In the present embodiment, the bottom surface of the groove 31 is a facing surface that faces the recording sheet P on which the first platen unit 27 is placed on the support surface 27a in the vertical direction at the position of the groove 31. ing.

  In addition, on the support surface 27a of the first platen unit 27, the intermediate region between the ribs 30 adjacent in the left-right direction, in which the concave groove 31 is not formed, is located outside and inside the first platen unit 27. A plurality of (two in this embodiment) circular suction holes 33 penetrating the support surface 27a of the first platen unit 27 in the vertical direction are formed so as to communicate with the space 29. Further, an opening 34 that communicates the outside of the first platen unit 27 and the internal space 29 is formed at the center of the lower surface of the first platen unit 27, and the suction fan 35 is closed so as to close the opening 34. An induction blower 36 having the above is provided. When the suction fan 35 is rotated by driving the induction fan 36, the inside of the first platen unit 27 is sucked through the opening 34 and negative pressure is generated in the internal space 29 of the first platen unit 27. Since the suction force from the suction hole 33 reaches the recording paper P placed on the support surface 27a, the recording paper P is attracted to the support surface 27a.

  Further, of the platen units 27 and 28 constituting the platen 14, the second platen unit 28 arranged on the downstream side in the conveyance direction of the recording paper P has a rear end surface that is substantially the same as the front end surface of the first platen unit 27. Arranged so that there is no gap. Further, in the vicinity of the support surface 28 a of the second platen unit 28, the position corresponding to each concave groove 31 on the support surface 27 a of the first platen unit 27 in the left-right direction is forward from the rear end surface of the second platen unit 28. Concave portions 37 (see FIGS. 5A and 5B) that are recessed substantially horizontally are formed. Further, in each concave portion 37, a cover member 38 configured so that the width dimension in the left-right direction with respect to each concave groove 31 of the first platen unit 27 is substantially the same is a rear end surface of the second platen unit 28. It is arranged so that it can move in and out in the front-rear direction.

  That is, the cover member 38 is formed in the concave portion 37 based on the driving force from the driving roller 39 disposed in the vicinity of the opening of the concave portion 37 from the state completely accommodated in the concave portion 37 (the state shown in FIG. 5A). While being slid with respect to the inner wall surface of 37, it is possible to move horizontally so that the front end portion protrudes from the rear end surface of the second platen unit 28 to a position where it abuts against the inner wall surface of the concave groove 31 of the first platen unit 27. It is. As shown in FIG. 5B, the cover member 38 can completely cover the opening of the concave groove 31 formed on the support surface 27 a of the first platen unit 27. In this respect, the cover member 38 functions as an opening / closing member that is driven so as to open / close the opening of the groove 31 formed on the support surface 27a of the first platen unit 27. In this embodiment, the cover member 38 and the driving roller 39 that drives the cover member 38 so as to change the open / closed state of the groove 31 on the support surface 27a are used. The changing means for changing the presence / absence state at is configured.

  In addition, on the support surface 28a of the second platen unit 28, as in the case of the first platen unit 27, a plurality of (this embodiment) having substantially the same shape as the ribs 30 on the support surface 27a of the first platen unit 27. Twelve ribs 40 in the form are formed in parallel with a space in the longitudinal direction of the second platen unit 28.

  Similarly, on the support surface 28a of the second platen unit 28, a plurality of (in this embodiment, 10) suction holes 41 having substantially the same shape as the suction holes 33 of the first platen unit 27 are provided in the second platen unit 28. The platen unit 28 is formed so as to penetrate the support surface 28 a of the second platen unit 28 in the vertical direction so as to communicate with the inside and outside of the platen unit 28.

  Similarly, an opening (not shown) that communicates the inside and outside of the second platen unit 28 is formed at the center of the lower surface of the second platen unit 28, and a suction fan is provided so as to close the opening. An induction blower (not shown) is provided. When the suction fan is rotated by driving the induction fan, the inside of the second platen unit 28 is sucked through the opening to generate a negative pressure, and the suction force from each suction hole 41 is supported by the generation of the negative pressure. The recording paper P is placed on the surface 28a.

  Next, regarding the operation of the printer 11 of the present embodiment, in particular, the operation when adjusting the shape of the recording paper P placed on the support surface 27a of the first platen unit 27 to be substantially planar. This will be described below with reference to FIGS. 6 and 7, the ribs 30 formed on the support surface 27a of the first platen unit 27 are omitted for the convenience of understanding the description.

  In the printer 11 of the present embodiment, when performing borderless printing on the recording paper P in which the margin in the width direction is zero, first, the paper feed motor 15 is rotationally driven to feed the paper feed tray. 13 is fed onto the support surface 27a of the first platen unit 27 that can be detected by the optical sensor 26.

  Subsequently, the printer 11 performs a single scan of the carriage 17 from the home position HP positioned outward in the width direction of the recording paper P along the guide shaft 16 so as to cross the recording paper P vertically in the width direction. Paper edges P1 and P2 in the width direction of the recording paper P are detected by the optical sensor 26, respectively. Then, the printer 11 calculates the dimension in the width direction of the recording paper P based on the positional information of the paper edges P1 and P2 of the recording paper P detected by the optical sensor 26.

  Here, as shown in FIG. 6, the recording sheet P fed onto the support surface 27 a of the first platen unit 27 has the support surface among the plurality of concave grooves 31 formed on the support surface 27 a. It is assumed that the optical sensor 26 detects that the dimension X1 in the width direction corresponding to the pair of concave grooves 31 formed at the position closest to the center in the left-right direction in 27a. In this case, the entire area of the recording paper P is supported on the support surface 27a in a state where the flatness is maintained by being uniformly supported by the support surface 27a of the first platen unit 27. Accordingly, when the printer 11 performs borderless printing with zero margin in the width direction on the recording paper P, ink is ejected from the recording head 22 to the recording paper P thus maintained in flatness. Therefore, sufficient print quality can be ensured for the recording paper P.

  On the other hand, as shown in FIG. 7 (a), the recording paper P fed onto the support surface 27a of the first platen unit 27 has a plurality of concave grooves 31 formed on the support surface 27a. It is assumed that the optical sensor 26 detects that the support surface 27a has the width direction dimension X2 corresponding to the pair of concave grooves 31 formed at the outermost position in the left-right direction. In this case, if the recording paper P is low in rigidity, it falls into the concave groove 31 located within the width of the recording paper P, so that the supporting surface 27a of the first platen unit 27 is greatly waved in the vertical direction. Therefore, the flatness cannot be ensured.

  Therefore, in the printer 11 of the present embodiment, a plurality of pieces formed on the support surface 27a of the first platen unit 27 based on the positional information of the paper edges P1 and P2 in the width direction of the recording paper P detected by the optical sensor 26. The concave groove 31 located within the width of the recording paper P, that is, the concave groove 31 whose opening on the support surface 27a is completely covered by the recording paper P is determined. Subsequently, in order to drive the cover member 38 on the second platen unit 28 side corresponding to each of the concave grooves 31, the corresponding driving roller 39 is driven to rotate.

  Then, as shown in FIG. 7B, each cover member 38 has the second platen unit 28 so as to close the opening on the support surface 27 a of each concave groove 31 positioned within the width of the recording paper P. It moves horizontally so that it protrudes from the recessed part 37 to the 1st platen unit 27 side. As a result, the concave grooves 31 positioned within the width of the recording paper P are closed at substantially the same height as the support surface 27a by the corresponding cover member 38. Therefore, the opposing surface in which the first platen unit 27 faces the recording paper P in the vertical direction at the position of the concave groove 31 on the support surface 27 a is separated in the vertical direction from the support surface 27 a of the first platen unit 27. The bottom surface of the recessed groove 31 is changed to the top surface of the cover member 38 that is close to the support surface 27a of the first platen unit 27 in the vertical direction. Therefore, the facing surface in which the first platen unit 27 faces the recording paper P in the vertical direction at the position of the concave groove 31 on the support surface 27a approaches the support surface 27a on which the recording paper P is placed. The relative position in the vertical direction with respect to the support surface 27a is changed in the direction.

  That is, when the first platen unit 27 in the present embodiment performs borderless printing for performing printing processing up to the edge in the width direction on the recording paper P placed on the support surface 27a, A first state in which the ink ejected from the recording head 22 can be received in the concave groove 31 at a position lower than the support surface 27a, and the opening of the concave groove 31 on the support surface 27a is closed by the cover member 38. Thus, the second state in which the recording paper P can be supported at substantially the same height as the support surface 27a by the upper surface of the cover member 38 at the position of the concave groove 31 on the support surface 27a is configured to be mutually changeable. Has been.

  At this time, the recording paper P slides with respect to the upper surface of the cover member 38 in accordance with the horizontal movement of the cover member 38 in the region that has fallen into the concave groove 31 positioned within the width of the recording paper P. It moves so that it rides up. As a result, the recording paper P is uniformly supported by the support surface 27a of the first platen unit 27 and the cover members 38 of the second platen unit 28, so that the recording paper P is supported in a state in which the flatness is maintained. It is mounted on the surface 27a. Therefore, when the printer 11 performs borderless printing with zero margin in the width direction on the recording paper P, the ink is applied from the recording head 22 to the recording paper P in which the flatness is maintained in this way. Therefore, a sufficient print quality can be ensured for the recording paper P.

According to the present embodiment, the following effects can be obtained.
(1) In the above embodiment, according to the widthwise dimension of the recording paper P, by driving the cover member 38 individually corresponding to the concave groove 31 completely covered with the recording paper P, the concave grooves are driven. The relative position in the up-down direction with respect to the support surface 27a of the opposing surface facing the recording paper P in the first platen unit 27 at the position 31 is changed. As a result, even if the recording paper P is low in rigidity, the ratio of the recording paper P to be bent and deformed by falling into the opening on the support surface 27a of the concave groove 31 is reduced. Therefore, the flatness of the recording paper P in a state where it is supported on the support surface 27a of the first platen unit 27 can be improved. Therefore, sufficient recording quality can be ensured when performing borderless printing with zero margin in the width direction on a plurality of recording papers P having different dimensions in the width direction.

  (2) In the above embodiment, based on the dimension in the width direction of the recording paper P detected by the optical sensor 26, the concave groove 31 at the position covered with the recording paper P on the support surface 27a is accurately determined. be able to. Accordingly, the concave grooves 31 are changed so that the relative positions in the vertical direction with respect to the support surface 27a of the facing surface facing the recording paper P in the first platen unit 27 at the positions of the concave grooves 31 are changed. By properly eliminating the opening on the support surface 27a, the flatness of the recording paper P can be improved more reliably.

  (3) In the above embodiment, the drive roller 39 opens and closes the cover member 38 provided for each groove 31, so that the recording in the first platen unit 27 at the position of the groove 31 on the support surface 27 a. The relative position in the vertical direction with respect to the support surface 27a of the facing surface facing the paper P can be easily changed.

The above embodiment may be changed to another embodiment as described below.
In the above embodiment, the optical sensor 26 may be disposed at a position upstream of the first platen unit 27 in the conveyance direction of the recording paper P. In this case, the printer 11 uses the first dimension based on the width dimension of the recording sheet P detected by the optical sensor 26 before the recording sheet P is fed onto the support surface 27 a of the first platen unit 27. Of the plurality of grooves 31 formed on the support surface 27a of the platen unit 27, each groove 31 is closed so as to close the opening on the support surface 27a of the groove 31 positioned within the width of the recording paper P. The cover member 38 corresponding to each can be driven individually.

  In the above embodiment, the first platen unit 27 may be divided into a plurality of unit units along the longitudinal direction. In this case, of the unit units constituting the first platen unit 27 according to the widthwise dimension of the recording paper P, the unit unit in which the groove 31 is formed is changed to the unit unit in which the groove 31 is not formed. By appropriately replacing, the entire area of the recording paper P can be evenly supported by the support surface 27a of the first platen unit 27. In this case, the upper surface of the unit unit in which the groove 31 is not formed is opposed to the recording paper P placed on the support surface 27a in the vertical direction at the position of the groove 31 on the support surface 27a. Is defined as the facing surface.

  In the above embodiment, the receiving portion formed on the support surface 27 a of the first platen unit 27 in order to collect the waste ink discarded outside in the width direction of the recording paper P is limited to the concave groove 31. For example, the through-hole which penetrates the 1st platen unit 27 to an up-down direction may be sufficient. In other words, any configuration can be adopted as long as it can receive waste ink at a position lower than the support surface 27a of the first platen unit 27.

  In the above embodiment, as long as the paper width sensor that detects the dimension in the width direction of the recording paper P can detect the recording paper P, another type of sensor can be used. For example, a contact type sensor may be used. It can also be adopted.

  In the above-described embodiment, when the operator performs borderless printing of the recording paper P, the operator may appropriately input information regarding the dimension in the width direction of the recording paper P. In this case, the paper width sensor that detects the dimension in the width direction of the recording paper P can be omitted.

  In the above embodiment, according to the widthwise dimension of the recording paper P, support of some of the plurality of concave portions located within the width of the recording paper P on the support surface 27a of the first platen unit 27 is supported. It is good also as a structure which lose | eliminates the opening on the surface 27a suitably.

In the above embodiment, a long roll paper may be applied as the recording medium. Further, as the recording medium, other materials such as a resin film may be applied instead of paper.
