<< First Embodiment >>
Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. Hereinafter, an outline of an ink jet printer (hereinafter referred to as “printer”) 1 as an example of a recording apparatus or a liquid ejecting apparatus will be described first with reference to FIGS. 1 and 2. Here, FIG. 1 is an external perspective view of the main body of the printer 1 (with the exterior case removed), and FIG. 2 is a cross-sectional side view of the same. Hereinafter, the right direction (front side of the printer) in FIG. 2 is referred to as “downstream side” of the paper or tray conveyance path, and the left direction (back side of the printer) is referred to as “upstream side”.

  The printer 1 includes a feeding device 2 capable of setting a recording sheet (mainly cut sheet paper: hereinafter referred to as “sheet P”) as an example of “recording medium” and “ejection medium” in an inclined posture at the rear part, The paper P is fed from the feeding device 2 toward the recording medium conveying means 4 on the downstream side. The fed paper P is conveyed by the recording medium conveying means 4 to the recording means 3 on the downstream side, and recording is executed. The paper P and the optical disk D (tray 50) on which recording has been performed by the recording means 3 are discharged forward by the recording medium discharge means 5 on the downstream side. The recording medium discharge means 5 also transports a tray 50 described later, and the recording means 3 executes recording on the optical disk D as a thin plate set on the tray 50.

Hereinafter, components on the paper conveyance path of the printer 1 will be described in more detail. The feeding device 2 includes a hopper 11, a feeding roller 12, a retard roller 13, and a return lever 14.
The hopper 11 is formed of a plate-like body, and is configured to be swingable around an upper swing fulcrum (not shown). By swinging, the paper P supported in an inclined posture is fed onto the hopper 11. The roller 12 is pressed against or separated from the feeding roller 12. The feeding roller 12 has a substantially D shape when viewed from the side, and feeds the uppermost sheet P pressed by the arc portion to the downstream side, while the recording medium after the sheet P is fed. During conveyance of the paper P by the conveyance means 4, the flat portion is controlled to face the paper P as shown in the figure so as not to cause a conveyance load.

  The retard roller 13 is provided so as to be in press contact with the arc portion of the feeding roller 12. When only one sheet P is fed without the double feeding of the sheet P, the retard roller 13 contacts the sheet P and rotates (clockwise in FIG. 2) to feed the sheet P. When there are a plurality of sheets between the feed roller 12 and the retard roller 13, the friction coefficient between the sheets is lower than the friction coefficient between the sheet P and the retard roller 13. Become. Therefore, this prevents the next and subsequent sheets P, which are to be double-fed by the uppermost sheet P to be fed, from traveling from the retard roller 13 to the downstream side, thereby preventing double feeding. The return lever 14 is provided so as to be rotatable, and has the effect of returning the next and subsequent sheets P about to be double fed onto the hopper 11.

A plurality of the drive driving rollers 30 are arranged in the axial direction.

Further, in the present embodiment, two transport driven rollers 31 are pivotally supported at the downstream end portion of one paper guide upper 24 so as to be freely rotatable, and three of the paper guide upper 24 are in the paper width direction, as shown in FIG. It is provided as shown. In addition, the paper guide upper 24 is provided so as to be swingable about the shaft 24 a when the shaft 24 a is pivotally supported by the main frame 23, as viewed from the side of the paper conveyance path. Is urged in a direction in pressure contact with the conveyance drive roller 30.
The sheet P that has reached the recording medium conveying unit 4 is conveyed to the recording unit 3 on the downstream side by the rotation of the conveyance driving roller 30 while being nipped by the conveyance driving roller 30 and the conveyance driven roller 31. .

  The recording unit 3 includes an inkjet recording head (hereinafter referred to as “recording head”) 36 and a paper guide lower portion 37 provided to face the recording head 36. The recording head 36 is provided at the bottom of the carriage 33. The carriage 33 is driven to reciprocate in the main scanning direction by a drive motor (not shown) while being guided by a carriage guide shaft 34 extending in the main scanning direction. In addition, the carriage 33 is equipped with an independent ink cartridge 35 for each of a plurality of colors, and supplies ink to the recording head 36.

  The paper guide 37 that defines the distance between the paper P and the recording head 36 has ribs (not shown) on the surface facing the recording head 36 and a recess (not shown) for discarding ink. , And so-called borderless printing is performed in which printing is performed without margins on the edge of the paper P by discarding the ink ejected to the area off the edge of the paper P in the recess.

  Subsequently, a guide roller 43 and a recording medium discharge unit 5 are provided on the downstream side of the recording head 36. The guide roller 43 functions to prevent the paper P from being lifted from the paper guide bottom 37 and to keep the distance between the paper P and the recording head 36 constant. The recording medium discharge means 5 includes a discharge drive roller 41 that is rotationally driven by a motor (not shown), and a discharge driven roller 42 that rotates in contact with the discharge drive roller 41. In the present embodiment, a plurality of discharge drive rollers 41 are provided in the axial direction of a shaft body that is made of a rubber roller and is rotationally driven (see FIG. 10).

  The discharge driven roller 42 is formed by a toothed roller having a plurality of teeth on the outer periphery, and a plurality of discharge drive rollers 41 are disposed on a discharge frame Assy (driven roller support means) 45 having a long shape in the main scanning direction. A plurality are provided so as to correspond to the above. The paper P on which recording has been performed by the recording means 3 is driven forward by the discharge drive roller 41 while being nipped by the discharge drive roller 41 and the discharge driven roller 42, so that the paper P is directed toward the front of the apparatus (not shown). Discharged.

  The discharge frame Assy 45 as the driven roller support means is provided so as to be displaceable so that a contact position where the discharge driven roller 42 contacts the discharge driving roller 41 and a separation position where the discharge driven roller 42 is separated from the discharge driving roller 41 can be taken. ing. Further, release means for displacing the paper discharge frame Assy 45 from the contact position to the separation position is provided, which will be described in detail later.

  The above are the components on the paper conveyance path. The printer 1 can directly perform inkjet on the label surface of an optical disc (thin plate-like body) such as a CD-R in addition to a cut sheet as a recording medium or an ejection medium. It is configured to be recordable. As shown in FIG. 1, the optical disc D is transported through a linear tray transport path in the printer 1 in a state of being set on a tray 50 having a plate shape. The tray 50 is configured separately from the printer 1 and is manually inserted into the tray conveyance path toward the rear side (upstream side) of the printer 1 while being supported by a tray guide 7 provided in front of the printer 1.

Hereinafter, the configuration of the tray 50 will be described with reference to FIG. Here, FIG. 3 is a plan view of the tray 50.
As shown in FIG. 3, the tray 50 has a rectangular shape in plan view, has a plate shape that can be nipped by a discharge driving roller 41 and a pressing roller 63 (described later), and with the rotation of the discharge driving roller 41. Thus, sub-scan feed is possible (details will be described later). The tray 50 is nipped by the transport driving roller 30 and the transport driven roller 31 and can be sub-scan fed along with the rotation of the transport driving roller 30.

  The tray 50 is integrally formed of a resin material so as to include a tray main body 51 and a set portion 52. As shown in the figure, the set portion 52 is constituted by a concave portion having a circular shape in plan view. A convex portion 53 is formed at the center of the set portion 52, and when the optical disc D is set in the set portion 52, a center hole (not shown) of the optical disc D is fitted into the convex portion 53, thereby the optical disc D. The position in the set portion 52 is determined. Incidentally, holes 54 and 54 formed around the set portion 52 are holes for ejecting the optical disc D.

  The up and down direction in FIG. 3 is the transport direction of the tray 50. As described above, when the tray 50 is inserted (feeded) into the transport path of the tray 50 via the tray guide 7, the top of FIG. It is designed to be inserted as a tip. That is, reference numeral 56 indicates the front end of the tray 50. Then, when inserting the tray 50 into the conveyance path of the tray 50, the tray 50 is inserted toward the rear side of the printer 1 through the tray guide 7 with the leading end 56 of the tray 50 as a head. At this time, the discharge driven roller 42 is separated from the discharge drive roller 41 by a release means described later, the pressing roller 63 (FIG. 2) advances into the conveyance path, and the tray 50 is moved by the discharge drive roller 41 and the pressure roller 63 ( It is in a state of being pinched (when the conveyance path is viewed from the side). In this state, the discharge driving roller 41 is rotationally driven to convey the tray 50 (details will be described later).

  The outline of the printer 1 has been described above. Hereinafter, the discharge frame Assy 45 and the release unit for displacing the discharge frame Assy 45 from the contact position to the separation position will be described in detail with reference to FIGS. 4 to 9. 4 and 5 are external perspective views of the paper discharge frame Assy 45, FIG. 6 is an external perspective view of the release member 60 (release means 6), FIG. 7 is an enlarged perspective view of the mounting portion of the release member 60, FIG. FIG. 9 is a side cross-sectional view of the tray conveyance path around the paper discharge frame Assy45.

As shown in FIG. 4, the paper discharge frame Assy 45 includes a paper discharge frame 46 formed of a metal plate material and a roller support member 47 formed of a resin material, and is in the main scanning direction (paper width direction). It has a shape that extends.
A holder portion 44 that pivotally supports the discharge driven roller 42 is integrally formed on the roller support member 47 so as to be localized in the main scanning direction, and a bearing portion that pivotally supports a release member 60 described later. 47a and 47a are integrally formed.
6 and 7 are guide ribs for smoothly guiding the paper P to the downstream side when the paper P such as plain paper is discharged.

  On the other hand, as shown in FIG. 6, the release member 60 constituting the release means 6 is formed by a shaft body extending in the main scanning direction, and the shaft end portions 60a and 60a thereof are the bearing portions 47a, The roller support member 47 is held by being fitted to 47a in a snap-fit manner. As shown in FIG. 7, when the paper discharge frame 46 is fitted to the roller support member 47, it is ensured that the retaining portion 46a formed on the paper discharge frame 46 does not drop the shaft end portion 60a from the bearing portion 47a. It is configured to hold on. Thus, the release member 60 is pivotally supported by the paper discharge frame Assy 45 so as to be rotatable.

  Next, as shown in FIGS. 6 and 7, a lever portion 61 is formed in the vicinity of one shaft end portion 60a of the release member 60, and further in the vicinity of the lever portion 61 and in the vicinity of the other shaft end portion 60a. The pressing roller 63 constituting the “pressing portion” (for example, formed of a rubber roller) is rotatably supported by the bearing portion 62.

Hereinafter, the operation of the release member 60, particularly the relationship between the lever portion 61 and the pressing roller 63 will be described with reference to FIGS. 8 and 9.
8 shows a state where the discharge driven roller 42 is in contact with the discharge drive roller 41 (contact position of the paper discharge frame Assy 45), and FIG. 9 shows a state where the discharge driven roller 42 is separated from the discharge driven roller 41 (discharge paper frame Assy 45). ) Is shown.

  In FIG. 8 showing the contact position of the paper discharge frame Assy 45, the lever portion 61 protrudes into the transport path of the tray 50 and the pressing roller 63 is retracted from the transport path of the tray 50 as shown. Note that the release member 60 is provided in a state in which a turning tendency is urged so that the lever portion 61 protrudes into the conveyance path of the tray 50 by a biasing force of a biasing means (for example, a torsion spring) (not shown). (The arrow d direction in FIG. 8).

  In this state, when the tray 50 is manually inserted into the tray conveyance path from the front of the apparatus (downstream of the tray conveyance path) to the rear of the apparatus (upstream of the tray conveyance path) (in the direction of arrow e in FIG. 8), As shown in FIG. 9, the tray 50 pushes up the lever portion 61, the release member 60 rotates, and the paper discharge frame Assy 45 is displaced upward as the release member 60 rotates. That is, when the release member 60 is pushed upward by the tray 50, the paper discharge frame Assy45 is displaced from the contact position to the separation position.

  Here, a guide frame 48 as a “positioning member” is provided above the paper discharge frame Assy 45, and a protrusion 45 a that protrudes toward the guide frame 48 is provided at the downstream end of the roller support member 47. Is formed. Then, as shown in FIG. 9, the projection 45 a comes into contact with the lower surface of the guide frame 48 (the surface facing the sheet ejection frame Assy 45), so that the sheet ejection frame Assy 45 is positioned at the separation position.

  In this separated position, as shown in FIG. 9, the paper discharge frame Assy 45 is held in a substantially horizontal position. This is the main scanning area of the carriage 35 above the upstream side of the discharge frame Assy 45, as shown in the figure. For example, the posture of the discharge frame Assy 45 is so that the upstream side of the discharge frame Assy 45 is obliquely upward. This is because the upstream end of the paper discharge frame Assy 45 interferes with the carriage 35 in the inclined posture. Therefore, by setting the paper discharge frame Assy 45 in the horizontal position at the separation position as described above, both the paper discharge frame Assy 45 and the carriage 35 are prevented from greatly interfering with each other, and the size of the apparatus is prevented from being increased. .

  Next, a coil spring 49 as “pressure contact means” is disposed between the paper discharge frame Assy 45 and the guide frame 48, and an urging force is provided so that the upstream side of the paper discharge frame Assy 45 is separated from the guide frame 48. Is acting. The urging force of the coil spring 49 acts so as to form a pressing force by which the pressing roller 63 presses the tray 50 toward the discharge driving roller 41 and a pressing force by which the projecting portion 45 a presses against the guide frame 48. . That is, as shown in FIG. 9, the principle of an insulator consisting of a force point (indicated by a symbol a), a fulcrum (indicated by a symbol b), and an action point (indicated by a symbol c) is formed. Accordingly, the discharge frame Assy 45 can stably hold the separation position, and the tray 50 can be reliably pressed toward the discharge drive roller 41.

  As described above, since the paper discharge frame Assy 45 is displaced to the separation position through the rotation of the release member 60, the release stroke of the paper discharge frame Assy 45 can be increased, and a link mechanism is employed. Thus, the release means can be configured at low cost without causing an increase in the number of parts. Further, since the tray 50 is inserted into the transport path, the tray 50 itself displaces the paper discharge frame Assy 45 from the contact position to the separation position, so that the discharge driven roller 42 is moved to the discharge driving roller without requiring any special operation. It is possible to reliably separate from 41, and it becomes possible to improve the user-friendliness. Further, since the tray 50 is pressed toward the discharge driving roller 41 by the pressing roller 63, the tray 50 is lifted, that is, the contact between the optical disk D set on the tray 50 and the discharge driven roller 42 can be reliably prevented. it can. Further, since the pressing roller 63 can freely rotate, the conveyance load when conveying the tray 50 can be kept to a minimum.

Next, the conveyance of the tray 50 by the discharge driving roller 41 and the pressing roller 63 will be described with reference to FIGS. 10 and 11 as well. Here, FIG. 10 is an external perspective view of the main body of the printer 1, and FIG. 11 is a front view thereof.
As shown in the change from FIG. 8 to FIG. 9, as the lever portion 61 is retracted from the transport path, the pressing roller 63 advances into the transport path and presses the tray 50 toward the discharge drive roller 41. Therefore, the tray 50 is sandwiched between the discharge driving roller 41 and the pressing roller 63 (as viewed from the conveyance path), and the tray 50 can be conveyed by the rotation of the discharge driving roller 41.

  In the present embodiment, the tray 50 is sub-scanned only by the rotation of the discharge driving roller 41 even when the actual recording is executed (the recording medium conveying unit 4 is not used). That is, the discharge driving roller 41 and the pressing roller 63 constitute a tray conveying unit that feeds the tray 50 in the sub-scanning direction.

  Here, the pressing roller 63 as the “first roller” is arranged on the recording surface side of the optical disc D, and as shown in FIGS. 10 and 11, an area other than the set portion 52 in the tray 50 (tray body 51). It is arranged to touch. That is, the tray transporting means for transporting the tray 50 is disposed on the recording surface side of the optical disc D, and the first roller (pressing roller 63) in contact with the area other than the set portion 52 in the tray body 51, and the tray body 51 And a second roller (discharge driving roller 41) in contact with the surface opposite to the surface in contact with the first roller.

  Therefore, the recording path of the optical disk D set on the tray 50 does not leave a roller passage mark, and it is possible to prevent a decrease in recording quality and obtain a good recording result. In addition, if the rollers pass through the set portion 52 of the tray 50, the rollers may pass through the stepped shape of the set portion 52, which may adversely affect the conveyance accuracy. Since this is in contact with the region, it is possible to prevent the decrease in the conveyance accuracy as described above.

  In addition, since the recording medium transporting means 4 is not used, that is, it is not necessary to consider the transport accuracy of sheet paper or the like (particularly, dedicated glossy paper for performing super-high quality printing equivalent to a silver salt photograph). The pressing force for pressing the tray 50 by the pressing roller 63 can be easily optimized. Therefore, it is possible to prevent the tray 50 from being damaged by strongly pressing the tray 50. Further, as described above, the transport driving roller 40 is provided with an adhesion layer in which the wear-resistant particles are substantially uniformly dispersed on the outer peripheral surface of the metal shaft. It is possible to prevent damage to the tray 50 due to the conveyance.

In addition, the tray 50 is manually inserted from the front side of the printer 1, but it is not necessary to nip the front end of the tray 50 with the recording medium conveying means 4 when recording on the optical disc D. The size of the portion (distance from the region of the set portion 52 to the tip 56: indicated by a symbol L in FIG. 3) can be shortened, and the tray can be downsized.
In the present embodiment, the leading end 56 of the tray 50 is positioned further upstream of the recording medium conveying means 4 at the start of recording on the optical disc D, so that the conveyance driven roller 31 is separated from the conveyance driving roller 30. Release means are provided (not shown).

  By the way, when the recording on the optical disc D is finished and the tray 50 is ejected (direction of arrow f in FIG. 8), the release member 60 is given a turning tendency in the direction indicated by the arrow d. The lever portion 61 acts to push the front end 56 of the tray 50 in the discharge direction (arrow f direction). Accordingly, the tray 50 can be discharged more smoothly, and the tray 50 can be discharged smoothly.

  Next, another characteristic configuration in the present embodiment will be described. In FIG. 11, an area B in the main scanning direction indicates an area through which a sheet P such as a cut sheet passes, and an area A indicates an area through which the tray 50 passes. As shown in FIG. Is located. Further, when the paper conveyance path is viewed from the side as shown in FIG. 8, the sheet P is retreated from the region through which the paper P such as a cut sheet passes at the contact position of the paper discharge frame Assy 45, and the paper discharge frame is shown in FIG. At the separation position of Assy 45, the sheet advances into the passage area of the sheet P such as a cut sheet.

  That is, if the pressing roller 63 is arranged outside the passage area B of the sheet P such as the cut sheet in the main scanning direction so as not to hinder the passage of the sheet P such as the cut sheet, the area A, That is, the width direction dimension of the tray 50 is increased. However, since the pressing roller 63 is located inside the passage area B of the sheet P such as a cut sheet in the main scanning direction, it is possible to prevent the tray 50 from increasing in the width direction and In the state in which the paper P passes (the contact position of the paper discharge frame Assy 45 shown in FIG. 8), the paper P is retreated from the passage area of the paper P such as cut paper, so that the passage of the paper P such as cut paper is not hindered. .

  A plurality (two in this embodiment) of the pressing rollers 63 are provided, and the positions in the main scanning direction are symmetrical with respect to the center of the tray 50 in the main scanning direction as shown in FIG. In the embodiment, since it is in the vicinity of both side edges of the tray 50, when the tray 50 is transported by the pressing roller 63 and the discharge drive roller 41, it can be transported appropriately without causing a skew. .

Next, an erroneous insertion preventing means for preventing the tray 50 from being inserted from an incorrect position when the paper discharge frame Assy 45 is in the contact position will be described.
As shown in FIG. 1, the tray guide 7 is formed with guide ribs 74 and 75 that constitute erroneous insertion preventing means. The guide ribs 74 and 75 are provided at both side end positions of the tray 50 to regulate the side end position of the tray 50 and include eaves portions 74 a and 75 a, thereby preventing the tray 50 from being lifted from the tray guide 7. Fulfill.

  By the way, the tray 50 is not set correctly through the guide ribs 74 and 75. For example, the tray 50 is set so that one side end of the tray 50 rides on the upper part of the eaves 74a or 75a. If the front end of the tray 50 pushes up the release member 60 when inserted, the paper discharge frame Assy 45 is displaced from the contact position to the separation position. Accordingly, the tray 50 is inserted into the apparatus while being lifted from the tray guide 7, and the optical disk D set in the tray 50 comes into contact with the discharge driven roller 42. There is a risk of causing problems such as damage.

  However, the eaves portions 74 a and 75 a serve to guide the front end of the tray 50 so that the front end of the tray 50 comes into contact with the roller support member 47 when the side end of the tray 50 is placed thereon. Therefore, even if the tray 50 is inserted in a state where it is not correctly guided by the guide ribs 74 and 75, the front end of the tray 50 abuts on the roller support member 47, thereby preventing further entry, that is, the paper discharge frame Assy 45. Is not displaced from the contact position to the separated position, so that problems associated with erroneous insertion of the tray 50 can be prevented.

<< Second Embodiment >>
By the way, in the above embodiment, the tray transport means for transporting the tray 50 is configured to include the pressing roller 63 and the discharge drive roller 41, and this is configured by the transport drive roller 30 and the transport driven roller 31. May be. That is, if the transport driven roller 31 is disposed so as to be in contact with an area other than the setting portion 52 of the tray 50, the recording surface of the optical disk D set on the tray 50 is not left, and the recording quality of the recording is not left. It is possible to prevent deterioration and obtain a good recording result.

  In such a configuration, if the tray 50 is configured as shown in FIGS. 12 and 13 (a tray indicated by reference numeral 50A), a mechanism for releasing the transport driven roller 31 from the transport driving roller 30 when the tray is inserted becomes unnecessary, and the cost is low. Can contribute to Here, FIG. 12 is a plan view of a tray 50A according to another embodiment, and FIG. 13 is an external perspective view of the front end of the tray 50A. The same components as those of the tray 50 shown in FIG. 3 are denoted by the same reference numerals, and the description thereof is omitted below.

At the front end of the tray 50A, tongue pieces 57, 57 are formed integrally with the tray 50 so as to protrude in the insertion direction of the tray 50A.
As shown in FIG. 13, the tongue piece portion 57 is tapered toward the tip, and its bottom surface forms a flat surface together with the bottom surface of the tray main body 51. Also, the tip 56A of the tray 50A is formed so as to taper toward the tip, like the tongue piece 57.

  The tongue piece 57 has the following effects. That is, when inserting the tray 50A into the transport path of the tray 50A, the tray 50A is inserted toward the rear side of the printer 1 through the tray guide 7 with the leading edge 56A of the tray 50A as a head. At this time, the discharge driven roller 42 is separated from the discharge drive roller 41 by the release means 6 described above, and the pressing roller 63 (FIG. 2) advances into the conveyance path, and the tray 50A is moved by the discharge drive roller 41 and the pressure roller 63. It is in a state of being pinched (when the conveyance path is viewed from the side). In this state, the discharge driving roller 41 is rotationally driven, so that the tray 50 </ b> A is conveyed toward the recording medium conveying unit 4.

  In order to perform sub-scan feeding of the tray 50A by the transport driving roller 30 and the transport driven roller 31, the front end 56A of the tray 50A needs to be inserted between the transport driving roller 30 and the transport driven roller 31. Since the tongue piece 57 is formed at the tip 56A of the recording medium, when the tray 50A is conveyed toward the recording medium conveying means 4 as the discharge driving roller 41 rotates, the tongue piece 57 is driven to convey. It enters between the roller 30 and the transport driven roller 31, and this triggers the leading edge 56A of the tray 50A to enter between the transport driving roller 30 and the transport driven roller 31, and the tray 50A is eventually nipped by both rollers. The

  That is, the area of the front end of the tray 50A (by a plan view) is extremely reduced by the tongue piece 57, so that the front end 56A of the tray 50A can be easily inserted between the transport driving roller 30 and the transport driven roller 31 with a small force. Can do. Accordingly, the transport driving roller 30 and the transport driven roller can be operated by the cooperative action of the discharge drive roller 41 and the pressing roller 63 without using a means for separating (release) the transport driven roller 31 from the transport driving roller 31. 31.
