Description

  The present invention relates to a recording medium discharging apparatus that discharges a recording medium on which recording is performed, and a recording apparatus including the recording medium discharging apparatus.

  Conventionally, as a kind of recording apparatus, liquid is ejected from a recording head provided in a recording unit to a recording medium that is unwound from a rolled state and conveyed so as to pass through the recording unit. Ink-jet printers that perform recording and then cut and eject the recording medium into a predetermined length are widely known. For example, as disclosed in Patent Document 1, this type of printer is usually a large printer, and a printer main body (apparatus) having a printing unit (recording unit) that records on a recording medium on the upper side in the vertical direction. A main body) and a paper discharge stack portion (medium receiving surface) disposed below the main body of the apparatus.

  In such a large-sized printer, as disclosed in Patent Document 1, for the sake of workability and space saving in the horizontal direction, the conveyance direction of the recording medium conveyed in the apparatus main body is inclined with respect to the horizontal direction. In addition, a medium support surface for discharging the recording medium after recording toward the medium receiving surface on the downstream side in the transport direction is provided to be inclined similarly to the transport direction. Then, when the recording medium cut after the recording is performed is ejected from the apparatus main body by moving (falling) along the inclined medium support surface, the leading edge in the ejecting direction is set to the medium receiving portion. The recording surface is curved so that the recording surface on which the recording is performed is opposed to the medium receiving surface. Due to this curvature, the leading edge in the discharge direction of the recording medium becomes an acute angle with a small contact angle with the medium receiving surface, moves along the medium receiving surface, and the medium receiving surface in a face-down state where the recording surface is on the lower side. Discharged to the top.

JP 2000-71535 A

  However, in the large-sized printer disclosed in Patent Document 1, if the contact angle when the leading edge in the discharge direction of the discharged recording medium is in contact with the medium receiving surface is an angle close to a right angle, A state occurs in which the leading edge in the discharge direction does not move smoothly along the medium receiving surface. For this reason, the cut recording medium may be folded on the medium receiving surface to block the medium receiving surface. Then, the recording medium on which recording has been performed cannot move on the medium receiving surface blocked by the previously ejected recording medium, and is not properly conveyed in the recording unit, so that the recording is correctly performed. It will not be done.

  The present invention has been made in order to solve the above-described problems, and has as its main object a medium discharge device that appropriately discharges a recording medium onto a medium receiving surface, and a recording device including the medium discharge device. It is to provide.

  In order to achieve the above object, the recording medium discharge device of the present invention supports the recording medium to be discharged by abutting on the surface opposite to the recording surface of the recording medium and supports the recording medium horizontally. A medium support surface that is inclined so that the downstream side in the discharge direction of the recording medium is downward, and a medium discharge section that discharges the recording medium in the direction of gravity along the medium support surface; A medium receiving portion for receiving the recording medium discharged from the medium discharging portion by a medium receiving surface provided so as to intersect with an extension line of the medium supporting surface at a position away from the discharging portion in the gravity direction side; The recording medium ejected from the medium ejecting section is curved so that the recording surface and the medium receiving surface face each other after the leading edge in the ejecting direction is brought into contact with the medium receiving surface. Discharged onto the medium receiving surface. A recording medium discharge device, wherein the medium support surface provided in the medium discharge portion is inclined at a first inclination angle that is inclined with respect to the horizontal and smaller than the first inclination angle with respect to the horizontal. Medium support surface changing means for changing between the second inclination angle and the second inclination angle.

  According to this configuration, when the inclination angle of the medium support surface is changed, the discharge direction of the recording medium discharged from the medium discharge unit is changed along the medium support surface. Then, the recording surface of the recording medium and the medium receiving surface are opposed to the recording medium in the middle of discharging, in which the base end side is supported by the medium supporting surface and the leading end side protrudes from the medium discharging portion. The bending force acting to bend into the state can be changed. For example, when the tilt angle of the medium support surface is changed from the first tilt angle to the second tilt angle, the recording medium discharge direction is changed to a direction approaching the horizontal direction. Then, the bending force acting so as to bend the recording medium being ejected from the medium ejecting portion is changed in a direction to increase. As a result, the recording medium is surely curved by the bending force so changed so that the recording surface side becomes a convex surface, and the leading edge of the recording medium in contact with the medium receiving surface and the medium receiving surface The inner angle formed by the lens, that is, the contact angle, is easily small. As a result, the recording medium after the leading edge in the ejection direction comes into contact with the medium receiving surface smoothly moves along the medium receiving surface so that the recording surface faces the medium receiving surface. Properly discharged onto the media receiving surface.

In the recording medium discharging apparatus of the present invention, the medium receiving surface is inclined at a third inclination angle in a direction opposite to the direction in which the medium supporting surface is inclined with respect to the horizontal.
According to this configuration, the recording medium ejected from the medium ejecting section easily moves in the direction of gravity along the medium receiving surface after the leading edge in the ejecting direction contacts the medium receiving surface. As a result, the recording surface is appropriately discharged onto the medium receiving surface in a state of facing the medium receiving surface, that is, in a face-down state.

  In the recording medium ejection apparatus of the present invention, an angle obtained by adding the first inclination angle of the medium support surface and the third inclination angle of the medium receiving surface is an angle larger than 90 degrees, and the medium support surface The angle obtained by adding the second inclination angle and the third inclination angle of the medium receiving surface is an angle smaller than 90 degrees.

  According to this configuration, the recording medium ejected along the medium support surface having the first inclination angle is the internal angle formed by the leading edge in the ejection direction that contacts the medium receiving surface of the recording medium and the medium receiving surface, Since the contact angle is an acute angle, the leading end of the recording medium in the discharge direction after coming into contact with the medium receiving surface is easily moved along the medium receiving surface. On the other hand, a force is applied to the recording medium that has been ejected along the medium support surface with the second inclination angle and then comes into contact with the medium receiving surface so that the recording surface becomes a convex surface. Therefore, the recording medium is reliably curved and the contact angle with the medium receiving surface is easily reduced.

In the recording medium ejecting apparatus of the present invention, the medium support surface changing means changes the inclination angle of the medium supporting surface according to the bending rigidity of the recording medium.
According to this configuration, it is possible to appropriately discharge various recording media having different bending rigidity, that is, waist strength, onto the medium receiving surface.

  In the recording medium discharge apparatus of the present invention, the distance along the direction of gravity between the discharge direction side end of the medium support surface of the second inclination angle and the medium receiving surface is the medium support surface of the first inclination angle. And a distance along the direction of gravity between the discharge direction side end and the medium receiving surface.

  According to this configuration, a larger bending force is applied to the recording medium ejected along the medium support surface having the second inclination angle than the recording medium ejected along the medium support surface having the first inclination angle. Can act.

  The recording apparatus of the present invention includes a recording unit that performs recording by ejecting liquid onto the recording surface of the recording medium before being discharged from the medium discharging unit to the recording medium, and the recording medium discharge having the above-described configuration. An apparatus.

  According to this configuration, the recording medium is placed on the recording surface and the medium receiver with respect to the recording medium that is in contact with the medium receiving surface by changing the discharge direction of the recording medium on which recording has been performed. It is possible to change the bending force that acts so as to bend the surface to face. Then, the recording medium can be surely bent by the changed bending force, and the inner angle, that is, the contact angle formed by the discharge direction front end portion of the recording medium in contact with the medium receiving surface and the medium receiving surface can be made acute. As a result, the recording medium after coming into contact with the medium receiving surface is appropriately placed on the medium receiving surface in a state where the leading end in the discharge direction moves along the medium receiving surface and the recording surface faces the medium receiving surface. Can be provided.

The ink is ejected onto the recording surface SP of the sheet ST from the recording head 42 of the carriage 41 that is reciprocally moved, and is recorded on the sheet ST.

  The discharge unit 15 includes a support surface forming member 51m formed with a medium support surface 51 that supports the sheet ST conveyed from the recording unit 14 by contacting the sheet ST with a surface opposite to the recording surface SP, and the medium support. And a support surface forming member 52m on which a medium support surface 52 connected to the downstream side in the transport direction of the sheet ST is formed. The medium support surfaces 51 and 52 are planes along the longitudinal direction of the apparatus main body 12 and have a width wider than the width dimension of the sheet ST. The medium support surface 52 is an inclined surface that is inclined forward and inclined at a predetermined inclination angle α (first inclination angle) from the horizontal. Incidentally, in this embodiment, α = 60 degrees. The support surface forming member 51m is provided on the recording unit 14 side, that is, on the upstream side in the transport direction of the sheet ST with respect to the support surface forming member 52m, and the medium support surface 51 is inclined closer to the horizontal direction than the medium support surface 52. It is assumed to be an inclined surface.

  After the sheet ST is supported by the medium support surface 51 and moves to the medium support surface 52, the sheet ST extends from the lower end 52 a in the inclined direction, which is the discharge direction side end of the medium support surface 52, below the apparatus main body 12 (on the gravity direction side) And is discharged toward the medium receiving portion 18 located at (1). Note that, at the joint between the medium support surface 51 and the medium support surface 52, a step 53 is formed in which the medium support surface 51 is the front side in a direction perpendicular to the medium support surface 52.

  At the positions corresponding to the left and right ends of the medium support surfaces 51 and 52 in the apparatus main body 12, a case side wall 22 (only the left side is shown in FIG. It is arranged as a member. Therefore, the front of the medium support surfaces 51 and 52 is an open space opened to the atmosphere that is not covered by the case body 21.

  The medium support surface changing means 17 is disposed so as to be positioned in an open space in front of the medium support surfaces 51 and 52. The medium support surface changing unit 17 includes a moving body 71 that is slidable in a direction perpendicular to the medium support surface 52, and a medium support surface 72 that is fixed to the moving body 71 and supports the sheet ST. The support surface forming member 72m is formed, and the guide member 25 is fixed to the case side wall 22 and guides the movement when the moving body 71 slides. The movable body 71 is formed with a grip portion 73 that is gripped when the movable body 71 is slid and moved on the opposite side of the discharge portion 15, and an engagement portion that engages with the guide member 25 on the discharge portion 15 side. 75 is formed. Then, when the engaging portion 75 slides while maintaining the engaged state with the guide member 25, the moving body 71 moves from the front upper side to the rear lower side so as to approach the medium support surface 52 of the discharge portion 15 (in the drawing). Slide in the direction indicated by the white arrow). The medium support surface 72 is a flat surface along the longitudinal direction, like the medium support surface 52, and is an inclined surface that is inclined downward from the horizontal.

  The cutting unit 16 is provided between the recording unit 14 and the discharge unit 15, and includes a rotary cutter 61 that is rotated by a driving unit (not shown) and moves in the width direction of the sheet ST. The rotary cutter 61 cuts the sheet ST by moving in the width direction of the sheet ST while cutting in the thickness direction of the sheet ST, and cuts the sheet ST into sheets having a predetermined length, that is, cut sheets CS.

  In the apparatus main body 12, the medium storage unit 13 is disposed on the upper rear side of the apparatus main body 12, and the discharge unit 15 is disposed on the lower front side of the apparatus main body 12. Then, the sheet ST unwound from the roll body RT includes a conveying roller provided in the recording unit 14 and includes an conveying roller (not shown) formed in the apparatus main body unit 12 from an obliquely upper rear side to an obliquely lower front side. To the discharge unit 15. After recording is performed on the recording surface SP of the sheet ST conveyed in the oblique direction in the recording unit 14, the sheet ST conveyed downstream in the conveyance direction and discharged from the discharge unit 15 is in the middle of the discharge. The sheet is cut to a predetermined length by the cutting means 16, becomes a cut sheet CS, and is discharged from the discharge unit 15.

  Next, the medium receiving unit 18 will be described. The medium receiving portion 18 is provided below the apparatus main body 12, and a base 81 connected to the apparatus main body 12 via the coupling member 19, and the sheet ST discharged from the discharge portion 15 of the apparatus main body 12. (And cut sheet CS) receiving surface forming members 82m and 83m. Each of the receiving surface forming members 82m and 83m is fixed at the both ends in the front-rear direction thereof by the base portion 81, so that the medium receiving surface 82 is provided on the rear side of the base portion 81 close to the apparatus main body portion 12. The medium receiving surfaces 83 are respectively formed on the front sides far away. Note that the rear medium receiving surface 82 is provided at a position spaced downward from the discharge unit 15 so as to intersect the extended line of the medium support surface 52 on the discharge direction side in the discharge unit 15. In the present embodiment, the receiving surface forming members 82m and 83m that form the medium receiving surfaces 82 and 83 are formed of a sheet material such as cloth. The receiving surface forming member 82m and the receiving surface forming member 83m may be formed of a single sheet material in which the materials are connected.

  The receiving surface forming member 82m is fixed in a straight line along the left-right direction by a rear end portion 86a of a fixing member 86 whose rear end edge is fixed to the base portion 81, and its front end edge is the front end portion of the base portion 81. It is fixed in a straight line along the left-right direction by a rod-like member 85 installed between the upper portions of a pair of support members 81b erected upward from both the left and right sides. The receiving surface forming member 82m is tensioned in the direction in which the front end edge and the rear end edge thereof are separated from each other, and is stretched as a whole. Further, the rod-shaped member 85 is disposed so as to be positioned above the rear end portion 86 a of the fixing member 86. As a result, the medium receiving surface 82 is a substantially flat surface, and is a rearwardly inclined surface inclined at an inclination angle β (third inclination angle) from the horizontal. Therefore, the medium receiving surface 82 is an inclined surface that is inclined in a direction opposite to the medium support surface 52 of the apparatus main body 12, which is an inclined surface that descends forward from the horizontal. In the present embodiment, the inclination angle β of the medium receiving surface 82 is set to an angle that is obtained by adding the inclination angle α of the medium support surface 52 to the obtuse angle larger than 90 degrees.

  In the middle of the medium receiving surface 82 that is flattened in this manner, a restricting portion 84 that restricts the sheet ST from moving rearward along the medium receiving surface 82 is provided. The restricting portion 84 is formed by a restricting member 88 in which one end portion 88 a is fixed to a fixing member 81 a constituting the base portion 81. In the present embodiment, the restricting member 88 is a wire member, and a part of the restricting member 88 functions as the restricting portion 84.

  The receiving surface forming member 83m is fixed in a straight line along the left-right direction by a front end portion 87a of an arm-shaped fixing member 87 whose front end edge is fixed to the base portion 81, and its rear end edge is a base. It is fixed in a straight line along the left-right direction by a rod-like member 85 installed between the upper portions of both support members 81b of the portion 81. The front end portion 87a of the fixing member 87 and the rod-shaped member 85 are arranged at a predetermined interval so that the receiving surface forming member 83m is bent, so that the medium receiving surface 83 is positioned on the lower side. It has a concave shape that is curved.

  Thus, the medium receiving portion 18 to which the receiving surface forming members 82m and 83m are fixed is the sheet ST (cut) discharged from the discharging portion 15 along the medium supporting surface 52 by the medium receiving surface 82 and the medium receiving surface 83. The sheets CS) are stacked with the recording surface SP on the lower side (face down) facing the medium receiving surfaces 82 and 83. For this reason, the medium receiving surfaces 82 and 83 are set such that the width dimension in the left-right direction is larger than the width dimension of the sheet ST (cut sheet CS). Further, even when the sheet ST is discharged while the discharge direction from the discharge unit 15 is maintained in the direction along the medium support surface 52, a bar shape is formed so that the leading edge SF in the discharge direction of the sheet ST contacts the medium receiving surface 82. The member 85 is disposed away from the extended surface of the medium support surface 52 of the discharge unit 15 by the dimension L1 toward the recording unit 14 in the direction perpendicular to the medium support surface 52.

  As described above, the medium receiving unit 18 has a function of receiving and stacking the sheets ST discharged from the discharge unit 15, so that the recording medium discharge device 100 is configured with the discharge unit 15. The base part 81 of the medium receiving part 18 also functions as the overall base of the recording apparatus 11.

  In the recording apparatus 11 including such a recording medium discharge apparatus 100, the discharge direction of the sheet ST discharged from the discharge unit 15 by the medium support surface changing unit 17 is different from the direction along the medium support surface 52. Can be changed. That is, as shown in FIG. 1, the user of the recording apparatus 11 grips the grip portion 73 in the medium support surface changing means 17, and moves the moving body 71 to the medium support surface 52 side of the discharge portion 15 (in the direction of the white arrow in the figure). ) And slide it.

  A state in which the moving body 71 is slid and moved will be described with reference to FIG. As shown in FIG. 2, when the moving body 71 that fixes the support surface forming member 72m on which the medium support surface 72 is formed slides to the medium support surface 52 side, the upper end 72b of the medium support surface 72 in the inclined direction is It is inserted so as to be positioned within the step 53 between the support surface 51 and the medium support surface 52. For this reason, the sheet ST conveyed and moved from the recording unit 14 side positioned above to the discharge unit 15 side positioned below is placed on the opposite side of the recording surface SP by the medium support surface 72 following the medium support surface 51. The surface is supported. Accordingly, the sheet ST discharged from the discharge unit 15 is discharged from the lower end 72a in the inclined direction, which is the discharge direction side end of the medium support surface 72, with the direction along the medium support surface 72 as the discharge direction.

  As described above, the medium support surface 72 is a plane along the longitudinal direction (left-right direction) of the apparatus main body 12 in the same manner as the medium support surface 52. In the present embodiment, the medium support surface 72 has an inclination angle γ (second inclination angle) with a gentle forward downward inclination angle closer to the horizontal than the inclination angle α of the medium support surface 52. . In the present embodiment, the inclination angle γ of the medium support surface 72 is set to an angle at which the value obtained by adding the inclination angle β of the medium receiving surface 82 is an acute angle smaller than 90 degrees. Incidentally, in this embodiment, γ = 5 degrees.

  Accordingly, in the recording apparatus 11, the discharge direction of the sheet ST is changed by the medium support surface changing unit 17 to a direction close to horizontal. Of course, the moving body 71 can move in a direction away from the medium support surface 52 by the slide movement, that is, from the rear to the front, and the medium support surface 72 moves forward by this forward movement. The medium support surface 52 again supports the sheet ST following the medium support surface 51.

  In the recording apparatus 11, as shown in FIG. 1, the distance La between the lower end 52a of the medium support surface 52 and the medium receiving surface 82 is separated in the vertical direction. Further, as shown in FIG. 2, the lower end 72a of the medium support surface 72 and the medium receiving surface 82 are separated by a distance Lb in the vertical direction. In the present embodiment, the distance La and the distance Lb are set to substantially equal dimensions.

  In the recording apparatus 11 of the present embodiment, a plurality of types of sheets ST having different rigidity are used as the sheet ST. Then, depending on the rigidity of the sheet ST used, the medium support surface used when the sheet ST is discharged is changed from the medium support surface 52 to the medium support surface 72 by the medium support surface changing means 17 or by the user. Conversely, the medium support surface 72 is changed to the medium support surface 52. By this change, the operation at the time of discharging the sheet ST in the recording medium discharging apparatus 100 is different. This different operation will be described below.

  First, in the recording medium discharge apparatus 100, FIGS. 3A, 3B, and 3C illustrate operations when the relatively stiff sheet ST is discharged from the discharge unit 15 along the medium support surface 52. FIG. ) Will be described.

  As shown in FIG. 3A, the sheet ST, which is recorded on the recording surface SP by the recording unit 14 and conveyed, is in a direction along the medium support surface 52 (white arrow H1 in the drawing). ) In the discharge direction. When the predetermined length on the leading end side in the discharging direction is discharged, the leading edge SF in the discharging direction of the sheet ST comes into contact with the medium receiving surface 82. In this contact state, since the sheet ST is the roll body RT in the medium accommodating portion 13, the curl remains due to the rigidity of the sheet ST, and in the front end portion from the vicinity of the lower end 52a of the medium support surface 52 to the front end edge SF. A curved portion R1 bent so that the recording surface SP side becomes a convex surface is formed.

  From this state, when the sheet ST is further discharged from the discharge unit 15 along the medium support surface 52 (indicated by the white arrow H1 in the figure), the sheet ST is discharged from the portion on the leading edge SF side of the previously discharged sheet ST. The portion of the sheet ST that is subsequently discharged applies a force in the discharge direction. At this time, in the present embodiment, the leading edge SF of the sheet ST that is in contact with the medium receiving surface 82 has a large internal angle, that is, the contact angle θ between the sheet ST and the medium receiving surface 82, so the medium receiving surface 82 and the leading edge SF It is assumed that the leading edge SF stays in a position in contact with the medium receiving surface 82 due to the frictional force acting between the two. Therefore, the force applied in the discharge direction acts on the discharged sheet ST as a bending force (arrow F1 in the figure) that rotates and curves the sheet ST with the leading edge SF as a fulcrum.

  Then, as shown in FIG. 3B, as a result of the action of the bending force, the discharged sheet ST is bent at the leading end portion to form a curved portion R2 having a smaller radius of curvature than the curved portion R1, and the leading edge. In SF, the contact angle θ between the sheet ST and the medium receiving surface 82 is further reduced. Accordingly, the leading edge SF is moved along the medium receiving surface 82 from the position in contact with the medium receiving surface 82 to the restricting portion 84 side.

  Further, as the curved portion R2 is formed at the leading end portion of the sheet ST, a curved portion R3 that is bent in the opposite direction to the curved portion R2 is formed in the vicinity of the lower end 52a of the medium support surface 52. The curved portion R3 has a larger curvature than the curved portion R2 because the rigidity of the sheet ST is high.

  In this state, when the sheet ST is further discharged from the discharge unit 15 along the medium support surface 52 (along the white arrow H1 in the figure), as shown in FIG. The SF moves along the medium receiving surface 82 and comes into contact with the restricting portion 84. By the movement of the leading edge SF to the restricting portion 84, the bending portion R2 and the bending portion R3 are each returned to bend, and the bending portion R4 having a large curvature radius is formed on the entire recording surface SP side as a convex surface. become.

  Thereafter, the sheet ST is cut when a predetermined length is discharged from the discharge unit 15, and is cut into cut sheets CS having a length corresponding to the recording range applied to the recording surface SP. The cut edge CS of the cut sheet CS is in contact with the restricting portion 84 on the medium receiving surface 82, while the rear edge SE of the cut sheet CS moves along the medium support surface 52 (51). As a result, a bending force (arrow F2 in the figure) is generated for the cut sheet CS to rotate and bend the cut sheet CS with the leading edge SF as a fulcrum.

  When the trailing edge SE of the cut sheet CS reaches the open space of the discharge unit 15 from the apparatus main body 12, the trailing edge SE is in a free state not supported by the medium support surface 52 (51). The rear end portion in the vicinity of the rear end edge SE of the cut sheet CS is moved forward by the bending force indicated by the arrow F2. Accordingly, as indicated by a thick broken line in the drawing, the rear end portion of the cut sheet CS is discharged to the medium receiving surface 83 with the recording surface SP facing down. As a result, the relatively stiff sheet ST is discharged from the discharge unit 15 along the medium support surface 52 with the inclination angle α, and the recording surface SP faces the medium receiving surfaces 82 and 83 to the medium receiving unit 18. Discharged.

  Next, in the recording medium discharge apparatus 100, the operation when the sheet ST having relatively low rigidity is discharged from the discharge unit 15 along the medium support surface 52 having the inclination angle α will be described with reference to FIGS. This will be described with reference to b) and (c).

  As shown in FIG. 4A, the sheet ST recorded on the recording surface SP by the recording unit 14 moves from the discharge unit 15 along the medium support surface 52 (open arrow H1 in the figure). When a predetermined length on the leading end side in the discharging direction is discharged, the leading edge SF contacts the medium receiving surface 82. In this contact state, the sheet ST is bent by forming a curved portion R5 having a small curvature radius at the lower end 52a of the medium support surface 52 because of its low rigidity. Then, the curled portion R5 and the leading end portion on the leading edge SF side of the sheet ST move downward along the vertical direction while drooping in a flat state with almost no bending since the curl is hardly left when it is the roll body RT. (The white arrow H3 in the figure). Then, when the predetermined length is discharged, the leading edge SF contacts the medium receiving surface 82.

  The contact angle θ formed by this contact between the sheet ST and the medium receiving surface 82 at the leading edge SF of the sheet ST is larger because of less bending than in the case of the highly rigid sheet ST. Accordingly, here, as in the case of the highly rigid sheet ST, the leading edge SF remains as it is in contact with the medium receiving surface 82. Accordingly, the portion of the sheet ST that is subsequently discharged from the discharge portion 15 along the medium support surface 52 applies a force in the discharge direction to the portion on the leading edge SF side of the previously discharged sheet ST, Using the leading edge SF as a fulcrum, a bending force (arrow F3 in the figure) is generated to rotate the sheet ST to bend.

  By the way, the leading end portion of the sheet ST is low in rigidity and in a flat state. Therefore, when such a bending force (F3) is applied, unevenness is generated along the width direction (left and right direction) of the sheet ST (waved). State). Accordingly, the low-stiffness sheet ST to which the bending force indicated by the arrow F3 acts is less likely to bend in the discharge direction (vertical direction) due to the wavy state in the width direction, and rotates in a flat state. Therefore, as a result of the action of the bending force, the sheet ST has the leading edge so that the portion where the curved portion R5 is formed is pushed forward by the sheet ST discharged from the discharge portion 15 along the medium support surface 52. Rotates using SF as a fulcrum.

  By this rotation, the sheet ST is displaced from the shape indicated by the thick broken line to the shape indicated by the thick solid line, as shown in FIG. That is, the bending portion R5 is pushed forward to form the bending portion R5a having a smaller radius of curvature than the bending portion R5. At the same time, in the vicinity of the lower end 52a of the medium support surface 52, a curved portion that bends in the opposite direction to the curved portion R5a due to the difference in the direction of the forward movement of the curved portion R5 and the discharge direction of the sheet ST. R6 is formed. Further, this rotation reduces the contact angle θ at the leading edge SF of the sheet ST, so that the leading edge SF of the sheet ST moves toward the restricting portion 84 along the medium receiving surface 82 (white in the figure). Open arrow H2).

  In this state, when the sheet ST is further discharged from the discharge unit 15 along the medium support surface 52 (white arrow H1 in the figure), the sheet ST is indicated by a thick broken line as shown in FIG. Displace from the shape to the shape indicated by the thick solid line. That is, the leading edge SF of the sheet ST moves along the medium receiving surface 82 so as to contact the restricting portion 84. As the tip edge SF moves backward, the curved portion R5a formed by being pushed forward tries to move backward, but the movement is suppressed by the curved portion R6 that bends in the opposite direction to the curved portion R5a. On the contrary, the formation position is moved to the side opposite to the leading edge SF as the sheet ST is discharged. For this reason, the curved portion R5a becomes a curved portion R5b having a smaller radius of curvature and is formed in front of the medium receiving surface 82. At the same time, since the bending force is applied to the curved portion R6 that is bent in the opposite direction by the portion of the sheet ST that is further discharged from the discharge portion 15 along the medium support surface 52, the curved portion R6 is on the rear edge SE side. A curved portion R6a having a smaller curvature radius is formed by being pushed down along the discharge direction. That is, the sheet ST is in a state of being folded by bending a portion connected to the leading edge SF through a plurality of small curved portions R5b and R6a.

  After that, the sheet ST is cut when a predetermined length is discharged from the discharge unit 15, and is cut into cut sheets CS having a length corresponding to the recording range provided on the recording surface. The cut sheet CS that has been cut is cut when the rear end edge SE that moves along the medium support surface 52 and the rear end portion that is the vicinity thereof are separated from the lower end 52a of the medium support surface 52 and are not supported. The rear end portion of CS falls downward (in the direction of gravity). For this reason, as indicated by an arrow F4 in the figure, a force in the direction of moving the rear end portion of the cut sheet CS backward acts on the cut sheet CS. As a result, the cut sheet CS having low rigidity is not discharged to the medium receiving surface 83, but is discharged in an inappropriate posture in which the rear end side of the recording surface SP is folded upward on the medium receiving surface 82. The

  Therefore, in the present embodiment, when a sheet ST having low rigidity is used, the medium support surface changing unit 17 of the recording medium discharge apparatus 100 causes the moving body 71 to slide and discharge the sheet ST from the discharge unit 15. By changing the support surface from the medium support surface 52 to the medium support surface 72, the sheet ST is discharged along the medium support surface having the inclination angle γ. Hereinafter, the operation when the sheet ST having relatively low rigidity is discharged along the medium support surface 72 will be described with reference to FIGS. 5A, 5B, and 5C.

  As shown in FIG. 5A, the sheet ST recorded on the recording surface SP by the recording unit 14 moves from the discharge unit 15 along the medium support surface 72 (open arrow H1 in the figure), When a predetermined length on the leading end side in the discharging direction is discharged, the leading edge SF contacts the medium receiving surface 82. In this contact state, the sheet ST becomes a curved portion R5 that is bent with a small radius of curvature at the lower end 72a of the medium support surface 72 because of its low rigidity. Then, the leading edge SF side of the sheet ST moves downward along the vertical direction while hanging down in a flat state with almost no curl when the roll body RT is left (the white arrow H3 in the figure). ), The leading edge SF of the sheet ST contacts the medium receiving surface 82.

  The contact angle θ formed by this contact between the sheet ST and the medium receiving surface 82 at the leading edge SF of the sheet ST is large as described with reference to FIG. 4A, and the leading edge SF is the medium receiving surface 82. It shall remain in the position where it touches. Therefore, the portion of the sheet ST that is subsequently discharged from the discharge portion 15 along the medium support surface 72 applies a force in the discharge direction to the portion on the leading edge SF side of the previously discharged sheet ST, Using the leading edge SF as a fulcrum, a bending force (arrow F5 in the figure) is generated for rotating and bending the sheet ST. Note that the low-stiffness sheet ST to which the bending force indicated by the arrow F5 acts similarly rotates in a planar state without bending its tip as in the description in FIG.

  At this time, the inclination angle γ of the medium support surface 72 is closer to the horizontal direction than the inclination angle α of the medium support surface 52, and the distance La = distance Lb. Therefore, the sheet ST discharged along the medium support surface 72 The rotational torque (moment force) having the tip edge SF acting on the fulcrum as a fulcrum becomes larger than that when discharged along the medium support surface 52. Therefore, since the force to rotate the discharged sheet ST portion forward with the leading edge SF as a fulcrum increases, the discharged sheet ST is curved with the recording surface SP side as a convex surface. The acting bending force (arrow F5) also increases.

  Accordingly, as a result of the action of the bending force, there is a portion connected to the leading edge SF in the sheet ST so that the curved portion R7 is pushed forward by the subsequent portion of the sheet ST discharged from the discharge portion 15 along the medium support surface 72. It rotates with the tip edge SF as a fulcrum. As a result of this rotation, the sheet ST is displaced from the shape indicated by the thick broken line to the shape indicated by the thick solid line, as shown in FIG. That is, the bending portion R7 is pushed forward to form the bending portion R7a. Further, this rotation reduces the contact angle θ between the sheet ST and the medium receiving surface 82 at the leading edge SF of the sheet ST. As a result, the leading edge SF of the sheet ST moves to the restricting portion 84 along the medium receiving surface 82 (white arrow H2 in the figure).

  On the other hand, with the formation of the curved portion R7a, a curved portion R8 that bends in the opposite direction to the curved portion R7a may occur in the vicinity of the lower end 72a of the medium support surface 72. Since the sheet ST is discharged along the medium support surface 72, which has a gentler inclination than the medium support surface 52, the bending force for bending the recording surface SP side as a concave surface is small. The portion R8 has a large radius of curvature even when it occurs.

  In this state, when the sheet ST is further discharged from the discharge unit 15 along the medium support surface 52 (white arrow H1 in the figure), the sheet ST is indicated by a thick broken line as shown in FIG. Displace from the shape to the shape shown by the thick solid line. That is, the leading edge SF of the sheet ST moves along the medium receiving surface 82 and comes into contact with the restricting portion 84. As the tip edge SF moves, the bending portion R7a moves rearward while changing to the bending portion R7b having a large radius of curvature, and bends the bending portion R8 so that the bending direction is reversed to be the bending portion R8a. Further, a curved portion R9 is formed in the vicinity of the lower end 72a of the medium support surface 72. As a result, a curved shape having the recording surface SP side as a convex surface is formed as a whole. The sheet ST is cut when a predetermined length on the leading end side in the discharge direction is discharged from the discharge unit 15, and is cut into cut sheets CS corresponding to the recording range applied to the recording surface SP. In the cut sheet CS that has been cut, the trailing edge SE moves along the medium support surface 72 (the white arrow H1 in the figure).

  As a result, the cut sheet CS is in a state in which curved portions R7b, R8a, and R9 are formed with the recording surface SP side as a convex surface when the trailing edge SE is discharged. Therefore, when the rear end edge SE of the cut sheet CS is not supported away from the lower end 72a of the medium support surface 72, the rear end portion of the cut sheet CS moves forward along the medium support surface 72. As indicated by an arrow F6 in the figure, the rear end portion of the cut sheet CS moves forward. As a result, the sheet ST having low rigidity is discharged onto the medium receiving surface 83 as the receiving surface of the rear end portion and the front end portion onto the medium receiving surface 82 with the recording surface SP facing down.

According to the embodiment described above, the following effects can be obtained.
(1) When the inclination angle of the medium support surface is changed, the discharge direction of the sheet ST discharged along the medium support surface is changed. Then, the recording surface SP and the medium receiving surface 82 face the sheet ST that is in the process of being discharged while the base end side is supported by the medium support surface and the leading end side protrudes from the discharge portion 15. The bending force acting so as to be bent can be changed. For example, when the inclination angle of the medium support surface that discharges the sheet ST from the discharge unit 15 is changed from the inclination angle α (first inclination angle) to the inclination angle γ (second inclination angle), the discharge direction of the sheet ST Is changed to a direction approaching the horizontal direction. Then, the bending force acting so as to bend the sheet ST in the middle of discharge from the discharge unit 15 is changed in a direction that increases. As a result, the sheet ST is reliably curved by the bending force so changed so that the recording surface SP side becomes a convex surface, and the leading edge SF and the medium receiving surface of the sheet ST in contact with the medium receiving surface 82 in the discharging direction. The internal angle formed by 82, that is, the contact angle θ, is easily an acute angle. As a result, the sheet ST after the leading edge SF in the discharge direction contacts the medium receiving surface 82 moves along the medium receiving surface 82 and the recording surface SP moves to the medium receiving surface 82. Are appropriately discharged onto the medium receiving surface 82.

  (2) Since the medium receiving surface 82 is inclined in the direction opposite to the medium support surfaces 52 and 72, the sheet ST discharged from the discharge unit 15 is not touched after the leading edge SF in the discharge direction contacts the medium receiving surface 82. It becomes easy to move to the regulating portion 84 on the gravity direction side along the medium receiving surface 82. As a result, the recording surface SP is appropriately discharged onto the medium receiving surface 82 in a state of facing the medium receiving surface 82, that is, in a face-down state.

  (3) The sheet ST discharged along the medium support surface 52 with the inclination angle α has an inner angle, that is, a contact angle formed by the leading edge SF in the discharge direction contacting the medium receiving surface 82 and the medium receiving surface 82 in the sheet ST. Since θ becomes an acute angle, the leading edge SF in the discharge direction of the sheet ST after coming into contact with the medium receiving surface 82 is easily moved along the medium receiving surface 82. On the other hand, a force is applied to the sheet ST that has been ejected along the medium support surface 72 with the inclination angle γ and then comes into contact with the medium receiving surface 82 so that the recording surface SP becomes a convex surface. Therefore, the sheet ST is reliably curved and the contact angle θ with the medium receiving surface 82 becomes an acute angle that is easily a small angle. Therefore, after contacting the medium receiving surface 82, the leading edge SF in the discharge direction of the sheet ST easily moves along the medium receiving surface 82 to the regulating portion 84 on the gravity direction side. As a result, the recording surface SP is reliably discharged onto the medium receiving surface 82 in a state of facing the medium receiving surface 82, that is, in a face-down state.

(4) Various types of sheets ST having different bending stiffness, ie, waist strength, of the sheet ST can be appropriately discharged onto the medium receiving surface 82.
(5) Since the distance along the direction of gravity between the lower ends 52a and 72a, which are the discharge direction side ends of the medium support surfaces 52 and 72, and the medium receiving surface 82 is substantially equal, along the medium support surface 72 with the inclination angle γ. Thus, a larger bending force can be applied to the sheet ST discharged than the sheet ST discharged along the medium support surface 52 with the inclination angle α.

  (6) By changing the discharge direction of the sheet ST on which the recording is performed on the recording surface SP, the recording surface SP and the medium receiving surface 82 make the sheet ST come into contact with the sheet ST in contact with the medium receiving surface 82. It is possible to change the bending force that acts to bend in the opposite state. Then, the sheet ST is reliably curved by the changed bending force so that the recording surface SP side becomes a convex surface, and the inner angle formed between the leading edge SF in the discharge direction of the sheet ST in contact with the medium receiving surface 82 and the medium receiving surface 82, that is, The contact angle θ can be an acute angle. As a result, the sheet ST after coming into contact with the medium receiving surface 82 is appropriate in a state where the leading edge SF in the discharge direction moves along the medium receiving surface 82 and the recording surface SP faces the medium receiving surface 82. In addition, the recording apparatus 11 discharged onto the medium receiving surface 82 can be provided.

In addition, you may change the said embodiment into another embodiment as follows.
In the embodiment described above, the medium support surface changing unit 17 causes the medium support surface 52 to function as the medium support surface 72 by displacing the support surface forming member 52m to change the inclination angle α of the medium support surface 52 It may be. This modification will be described with reference to FIG.

  As shown in FIG. 6, the medium support surface changing means 17 of the present modification changes the medium support surface 52 to the medium support surface 72 by rotating the support surface forming member 52 m on which the medium support surface 52 is formed. . That is, the support surface forming member 52m is attached to the upstream end portion in the discharge direction of the sheet ST so that the width direction (left-right direction) of the sheet ST is the axial direction and both ends of the shaft are rotatably attached to the apparatus main body 12. A rotating part 55 having a rotating shaft 56 is provided. Then, the medium support surface changing means 17 is rotated by the arcuate rack 57 having a gear formed on the outer periphery and the apparatus main body 12 as a rotating means for rotating the rotating portion 55 and fixed to the support surface forming member 52m. And a pinion 58 that is freely fixed and meshes with the rack 57. Therefore, the user rotates the support surface forming member 52m by rotating the rotating portion 55 around the rotation shaft 56 by rotating the pinion 58. For example, the medium support surface 52 is indicated by a two-dot chain line in the drawing. The position of the medium support surface 52 is changed. Accordingly, the medium support surface 52 functions as the medium support surface 72 in the above embodiment.

According to this modification, in addition to the effects (1) to (6) in the above embodiment, the following effects are obtained.
(7) Since the inclination angle of the medium support surface 52 can be continuously changed by the rotational displacement of the support surface forming member 52m, the discharge direction of the sheet ST discharged from the discharge unit 15 depends on the rigidity of the sheet ST. Can be set to the optimum direction. In addition, an increase in the number of members that form the medium support surface 72 can be suppressed.

  In the above embodiment, the recording medium ejecting apparatus 100 includes at least one medium support surface having a different inclination angle from the horizontal in addition to the medium support surface 52 and the medium support surface 72. You may make it change between these medium support surfaces. In this way, the sheet ST is discharged from the discharge unit 15 in an appropriate discharge direction in accordance with a plurality of sheets ST having different rigidity, and the sheet ST is appropriately placed on the medium receiving unit 18 with the recording surface facing the medium receiving surface. In this state, the cut sheet CS can be discharged and stacked.

  In the above embodiment, the distance Lb along the vertical direction between the lower end 72 a of the medium support surface 72 and the medium receiving surface 82 is along the vertical direction between the lower end 52 a of the medium support surface 52 and the medium receiving surface 82. It is preferable that the distance is larger than the distance La. In this case, the rotational torque for rotating the sheet ST discharged along the medium support surface 72 around the leading edge SF as a fulcrum is larger than that of the sheet ST discharged along the medium support surface 52. it can. Therefore, it is possible to reliably generate a bending force that acts to bend the sheet ST so that the recording surface SP and the medium receiving surface 82 face each other.

  In the above embodiment, the medium receiving surface 82 may be horizontal. In short, the medium receiving surface is not necessarily an angle that allows the sheet ST to be curved with the recording surface SP side convex while maintaining the state in which the leading edge SF in the discharge direction is in contact with the medium receiving surface 82. 82 may not be inclined.

  In the above embodiment, the angle obtained by adding the inclination angle α of the medium support surface 52 and the inclination angle β of the medium receiving surface 82 may be an angle smaller than 90 degrees. The angle is not necessarily limited to 90 degrees or more as long as the angle can be curved with the recording surface SP facing outward while maintaining the state in contact with the medium receiving surface 82.

  In the above embodiment, the recording medium discharge device 100 is not necessarily provided in the recording device 11 having the recording unit 14. For example, the present invention can be applied to any recording medium ejecting apparatus that receives a sheet that has already been recorded on the recording surface with the recording surface facing the gravity direction.

  In the above-described embodiment, the recording apparatus is embodied as the recording apparatus 11 having the liquid ejecting head that ejects ink as an example of the liquid as the recording head. However, the recording apparatus ejects or discharges liquid other than ink. A liquid ejecting apparatus may be embodied.

For example, it may be in a state in which the substance is in a liquid phase, such as a liquid with high or low viscosity, sol, gel water, other inorganic solvents, organic solvents, solutions, liquid resins, liquid metals (metal melts ) And liquids as one state of the substance, as well as particles in which functional material particles made of solid materials such as pigments and metal particles are dissolved, dispersed or mixed in a solvent. Further, representative examples of the liquid include ink and liquid crystal as described in the above embodiment. Here, the ink includes general water-based inks and oil-based inks, and various liquid compositions such as gel inks and hot melt inks.
