Description

  The present invention relates to a discharge medium receiving apparatus that receives and supports a discharge medium, a recording apparatus including the discharge medium receiving apparatus, and a liquid ejecting apparatus.

  As a recording medium, for example, there is an ink jet printer which is one of large recording apparatuses capable of recording even relatively large size paper such as JIS standard A0 size and JIS standard B0 size. In the case of such a large-sized ink jet printer, the paper on which recording has been completed is discharged from the paper discharge portion toward the front side obliquely downward and received by a paper discharge receiving device disposed below the paper discharge portion. It is like that.

  Roll paper or cut paper is used as the paper. In particular, there is a case where the curl remains at the leading edge of the roll paper, and a phenomenon occurs in which the paper tends to roll up in the vicinity of the paper discharge portion. Therefore, an ink jet printer is proposed in which a member that is supported in the vertical direction at the bottom of the paper discharge unit is provided, and the leading end of the roll paper that is discharged is brought into contact with this member to prevent the paper from being rolled up rearward. (See Patent Document 1).

The mounting portion 451 is formed in a box shape having an upper surface and one side surface opened. Positioning convex portions 451a are respectively provided at two corners on the upper edge of the upper surface opening facing the side surface opening. Locking claws 451b project from the two corners on the side opening at the upper edge of the upper opening. In addition, a locking projection 451e for holding the support portion 452 at a predetermined angle is provided below each locking claw 451b on the inner surface facing the two side surfaces 451c on which each locking claw 451b is formed. Further, a notch 451d for rotatably holding the rotation shaft 452c of the support portion 452 is formed below each of the locking convex portions 451e.

  The support part 452 is formed in a band plate shape, and includes a flat part 452a and a side part 452b integrated so as to sandwich the flat part 452a from both sides. In order to reduce the resistance when guiding and supporting the paper and improve the guidance and support accuracy, the edges of both side surface portions 452b protruding from the flat surface portion 452a function as guide support surfaces that contact the paper. Further, locking convex portions 452e that are locked to the rotating shaft 452c and the locking convex portions 451e of the mounting portion 451 protrude from both side surface portions 452b on one end side of the support portion 452, respectively. Further, a predetermined length of cut is made between the flat surface portion 452a and both side surface portions 452b from one end side to form a cantilever-shaped rotating shaft holding portion 452d. Further, the other end side of the support portion 452 is formed in a shape that warps against the guide support surface of the paper. Thus, the discharged paper can be guided along the curved shape, and can be gently displaced when the discharged paper is bent in the curved shape.

  The user picks the side surface portion 452b of the support portion 452 with his / her fingers from both sides and applies a force in the direction of the arrow embossed on the flat surface portion 452a to bend the rotating shaft holding portion 452d inward. In this state, the rotation shaft 452c of the support portion 452 is notched 451d of the mounting portion 451 so that the locking convex portion 452e of the support portion 452 is positioned above the locking convex portion 451e of the mounting portion 451. Insert into. Thereby, attachment of the support part 452 to the mounting part 451 is completed. Then, the positioning convex portion 451a of the mounting portion 451 is inserted into a positioning concave portion (not shown) formed on the lower surface of the printer main body, and the locking claw 451b of the mounting portion 451 is formed on the lower surface of the printer main body.

  The paper discharge support 450 having such a configuration is capable of adjusting the angle by turning around the rotation shaft 452c at the upstream end of the conveyance in a direction orthogonal to the conveyance direction in a side view indicated by an arrow c in FIG. That is, as shown in FIG. 10, the support part 452 is held at a right angle (vertical direction) with respect to the mounting part 451, and the support part 452 is attached to the mounting part 451 as shown in FIG. The opening angle can be adjusted to 120 degrees (a direction parallel to the paper discharge guide 131 and substantially parallel to the conveyance direction). When held at a right angle, roll-up of the discharged roll paper can be suppressed (hereinafter referred to as a roll-up suppression mode), and when held at 120 degrees, the discharged roll paper is discharged. Can be prevented (hereinafter referred to as “bending prevention mode”), and these functions will be described later.

  When adjusting from the winding prevention mode to the bending prevention mode, the user simply holds the support part 452 and lifts it up, and the locking convex part 452e of the support part 452 becomes the locking convex part 451e of the mounting part 451. From the upper side, it climbs over the locking projection 451e, enters under the locking projection 451e, and is locked. As a result, the support portion 452 is held at an opening angle of 120 degrees with respect to the mounting portion 451. On the other hand, when adjusting from the bending prevention mode to the hoisting suppression mode, the user picks the side surface portion 452b of the support portion 452 with fingers from both sides and applies a force in the direction of the arrow embossed on the flat surface portion 452a to rotate the rotation axis. The holding portion 452d is bent inward, and the locking convex portion 452e of the support portion 452 is moved over from below the locking convex portion 451e to release the locking state. Then, when the user removes his / her finger from the side surface portion 452b of the support portion 452, the support portion 452 hangs down by its own weight. As a result, the support portion 452 is held at a right angle with respect to the mounting portion 451 at an opening angle.

  FIGS. 13A, 13 </ b> B, and 13 </ b> C are three views showing details of the front upper hook member 420. The front upper hook member 420 has a structure in which a bar 422 made of a metal such as stainless steel is bent in a U-shape, and a holding member 423 made of plastic is fitted in the rear end. A guide portion 423a and a locking portion 423b, which will be described in detail later, are formed on the holding member 423 so as to protrude.

  FIG. 14 is a perspective view showing details of the hook holder 425. The hook holder 425 includes a first hook holder 426 and a second hook holder 427. The first hook holder 426 has a first groove portion 426a that penetrates from one end side to the other end side where the guide portion 423a of the holding member 423 can be inserted, and is formed in the first groove portion 426a. A second groove 426b into which the material 422 is slidably fitted is formed.

  The second hook holder 427 is formed in a closed groove portion 427a into which the guide portion 423a of the holding material 423 can be inserted and a closed end portion of the groove portion 427a. The locking portion 423b of the holding material 423 is formed in the second hook holder 427. A recess 427b is formed in which is attached and detached. The first hook holder 426 and the second hook holder 427 are arranged such that the first groove portion 426a and the groove portion 427a are connected with a space therebetween.

  In such a configuration, as shown in FIG. 9, each front upper hook member 420 can be pulled out in the direction indicated by the arrow a, that is, in the front direction of the ink jet printer 100 and pushed in the rear direction. That is, when the front upper hook member 420 is completely pulled out on the front side of the ink jet printer 100, the bar 422 is the second hook of the first hook holder 426 as shown in FIG. The guide portion 423a of the holding member 423 is fitted in the first groove portion 426a of the first hook holder 426. As a result, the front upper hook 421 is positioned and fixed.

  On the other hand, when the front upper hook member 420 is completely pushed into the front side of the ink jet printer 100, the bar 422 is the second of the first hook holder 426 as shown in FIG. The guide portion 423a of the holding member 423 slides toward the closed end portion along the groove portion 427a of the second hook holder 426, and the locking portion 423b of the holding member 423 is slid. Is fitted in the recess 427b. As a result, the front upper hook 421 is positioned and fixed.

  As shown in FIG. 16, the sheet member 440 is formed of a cloth or a soft plastic sheet in a rectangular shape, and both end portions and an intermediate portion thereof are moored along three shafts 441, 442, and 443, respectively. . The shafts 441, 442, and 443 are engaged with the rear hook member 410, the front upper hook member 420, and the front lower hook member 430. Usually, the shafts 441, 442, and 443 are locked to the hooks 410, 420, and 430 so as to be parallel to each other. The seat member 440 is configured to be detachable from the rear hook member 410, the front upper hook member 420, and the front lower hook member 430, but may be configured to be fixedly mounted.

  The receiving device 400 having the above-described configuration adjusts the angle of the paper discharge support 450 to guide and support the paper to be discharged corresponding to the type of paper to be used and the recording mode, and to turn it into the winding prevention mode. Switch to song prevention mode. Further, the usage mode can be changed by changing only the arrangement form of the front upper hook member 420 and the front lower hook member 430. That is, by switching the front upper hook member 420 back and forth and rotating the front lower hook member 430 back and forth, the front paper discharge mode and the rear paper discharge mode can be switched. A user operation when changing such a mode will be described with reference to FIGS.

  FIG. 17 is a diagram illustrating a state in which the rear paper discharge mode is set and the hoisting suppression mode is set. These modes are used when the paper type is roll paper other than mat paper, for example, and the recording mode is used when the duty is low, for example. Here, in the sheet member 440, both ends of the shaft 442 are already inserted into the respective rear hook members 410, and both ends of the shaft 443 are hooked on the U-shaped tip of the front upper hook member 420, It is assumed that both ends are hung on the U-shaped tip of the front lower hook member 430.

  First, the support portion 452 of the paper discharge support 450 is turned with respect to the mounting portion 451 and held so that the opening angle is a right angle. Next, the front upper hook member 420 is slid to the front of the ink jet printer 100 and completely pulled out, and then the front lower hook member 430 is rotated rearward of the ink jet printer 100 to be substantially vertical. The support pillar 142 is provided with a stopper that stops the rotation of the front lower hook member 430 in a substantially vertical state.

  As a result, the support portion 452 of the paper discharge support 450 hangs down in the vertical direction, so that even if curl remains at the front end of the discharged paper, the front end of the discharged paper is discharged. Abutting on the support portion 452 of the paper support 450, it is possible to prevent the paper from being rolled up rearward. Accordingly, the recording accuracy and the paper discharge accuracy can be maintained in a highly accurate state, and contact contamination with the recording head 121 can be prevented.

  Further, the U-shaped tip of the front upper hook member 420 is drawn forward from the paper discharge unit 130, and the shaft 443 locked to the front upper hook member 420 is changed to the rear hook member 410. The sheet member 440 up to the locked shaft 442 is in a state where it gently falls down on the back side of the ink jet printer 100. Accordingly, it is possible to receive the sheet in which the winding is suppressed from behind. At this time, the sheet member 440 from the shaft 443 locked to the front upper hook member 420 to the shaft 441 locked to the front lower hook member 430 is folded in a U-shape to be compact. Will be stored.

  FIG. 18 is a diagram illustrating a state in which the rear paper discharge mode is set and the bending prevention mode is set. These modes are used when the paper type is, for example, mat roll paper, and the recording mode is used when the duty is high, for example. Here, in the sheet member 440, both ends of the shaft 442 are already inserted into the respective rear hook members 410, and both ends of the shaft 443 are hooked on the U-shaped tip of the front upper hook member 420, It is assumed that both ends are hung on the U-shaped tip of the front lower hook member 430.

  First, the support portion 452 of the paper discharge support 450 is turned with respect to the mounting portion 451 and held so that the opening angle is 120 degrees. Next, the front upper hook member 420 is slid to the front of the ink jet printer 100 and completely pulled out, and then the front lower hook member 430 is rotated rearward of the ink jet printer 100 to be substantially vertical. The support pillar 142 is provided with a stopper that stops the rotation of the front lower hook member 430 in a substantially vertical state.

  As a result, the support portion 452 of the paper discharge support 450 is substantially flush with the paper discharge guide 131, so that cockling occurs in the paper that is discharged, and the paper is obliquely moved forward and downward from the paper discharge guide 131. Even if the sheet is discharged straight toward the sheet, the sheet is supported by the support portion 452 of the sheet discharge support 450, and bending at the end of the sheet discharge guide 131 due to the weight of the sheet can be prevented. Accordingly, it is possible to prevent fluctuations in the sheet posture in the vicinity of the recording head 121 and eliminate the occurrence of recording unevenness. A predetermined gap is provided between the front end of the support portion 452 of the paper discharge support 450 and the sheet member 440 so that the paper flows smoothly from the support portion 452 to the sheet member 440.

  Further, the U-shaped tip of the front upper hook member 420 is drawn forward from the paper discharge unit 130, and the shaft 443 locked to the front upper hook member 420 is changed to the rear hook member 410. The sheet member 440 up to the locked shaft 442 is in a state where it gently falls down on the back side of the ink jet printer 100. Therefore, it is possible to receive the sheet in which the folding is prevented at the rear. At this time, the sheet member 440 from the shaft 443 locked to the front upper hook member 420 to the shaft 441 locked to the front lower hook member 430 is folded in a U-shape to be compact. Will be stored.

  FIG. 19 is a diagram illustrating a state in which the front discharge mode is set. This mode is used, for example, for board paper that cannot be bent as a paper type, or for long printing that cannot receive paper with the sheet member 440 in the rear paper discharge mode. Here, in the sheet member 440, both ends of the shaft 442 are already inserted into the respective rear hook members 410, and both ends of the shaft 443 are hooked on the U-shaped tip of the front upper hook member 420, It is assumed that both ends are hung on the U-shaped tip of the front lower hook member 430.

  First, the support portion 452 of the paper discharge support 450 is turned with respect to the mounting portion 451 and held so that the opening angle is 120 degrees. Next, the front upper hook member 420 is slid rearwardly of the ink jet printer 100 to be fully pushed in, and then the front lower hook member 430 is rotated to the front of the ink jet printer 100 to be substantially horizontal. The support column 142 is provided with a stopper that stops the rotation of the front lower hook member 430 in a substantially horizontal state.

  As a result, the support portion 452 of the paper discharge support 450 is substantially flush with the paper discharge guide 131, so that the paper to be discharged can be prevented from being caught backward, and the paper to be discharged has cockling. Even if the generated paper is discharged straight from the paper discharge guide 131 toward the front side obliquely downward, the paper is supported by the support portion 452 of the paper discharge support 450 and the end of the paper discharge guide 131 due to the weight of the paper. Bending at the part can be prevented. Accordingly, it is possible to prevent fluctuations in the sheet posture in the vicinity of the recording head 121 and eliminate the occurrence of recording unevenness.

  Further, the U-shaped tip of the front upper hook member 420 is retracted rearward from the paper discharge unit 130, and the shaft 443 locked to the front upper hook member 420 is changed to the front lower hook member 430. The sheet member 440 between the locked shaft 441 and the ink jet printer 100 is gently dropped on the front side. Therefore, it is possible to receive the sheet in which the folding is prevented in the front.

  As described above, according to the sheet receiving device 400 of this embodiment, the sheet discharge support 450 that guides and supports the sheet discharged to the sheet member 440 has the conveyance upstream end in the direction orthogonal to the conveyance direction in a side view. Since the shaft is configured to be adjustable in angle, the paper can be guided and supported in accordance with the form of the paper to be discharged, and curling of the paper in the vicinity of the end of the paper discharge guide 131 can be suppressed. Can be prevented and bending can be prevented.

  Further, since the paper discharge support 450 is configured to be adjustable in angle at least in the vertical direction and in the direction parallel to the transport direction, the paper discharge support 450 is brought into contact with the paper discharge support 450 and discharged. The roll-up of the paper can be suppressed, and the paper to be discharged can be supported by the paper discharge support 450 from the back side to prevent the paper to be discharged from being bent. In the above-described embodiment, the angle adjustment of the paper discharge support 450 is performed in two stages, but may be performed in any stage.

  In addition, since a plurality of paper discharge supports 450 are arranged at predetermined intervals in the conveyance orthogonal direction, it is possible to deal with papers of various sizes. In the above-described embodiment, five paper discharge supports 450 are provided, but any number may be used. Further, since the discharge support 450 is formed in a shape in which the downstream end of the conveyance is warped with respect to the conveyance surface, the discharged paper can be guided along the curved shape, and the discharged paper is Can be gently displaced when bent in a curved shape.

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