Description

The present invention relates to a recording apparatus for conveying and recording a medium to be conveyed.
In the present application, “recording apparatus” includes types such as ink jet printers, line printers, copying machines, facsimiles, etc., and “conveyed medium” includes paper (cut sheet paper), optical disks, and optical disks. Such as tray, board, cardboard, etc.

  Conventionally, in a recording apparatus such as an ink jet printer, a sheet as one of the transported media is not only transported one by one along a transport path from a paper tray as a paper storage unit, but also recorded by the recording unit. There are some media that can transport an optical disk, board, or the like, which is one of the media, to a transport path and record it on a recording unit (for example, Patent Documents 1 and 2).

  In this recording apparatus, when recording a sheet having a certain degree of flexibility, such as plain paper, the sheet is fed from the feeding device to the recording unit, recorded by the recording unit, and then received by the sheet discharging means. It is sent out to the tray. On the other hand, since optical disks and board papers are low in flexibility (high in rigidity) and cannot be transported on a curved transport path, they differ from paper such as plain paper from the downstream side toward the transport path from the paper discharge means. Supplied horizontally.

  And after recording by the recording part, it discharges | emits horizontally toward the front of an apparatus. Since the optical disk is small in size and cannot be transported in the transport path of the recording apparatus as it is, in many cases, the optical disk is supplied into the transport path in a state of being set on a flat tray (hereinafter referred to as “disk tray”). The In the following description, for convenience of explanation, the transport medium with low flexibility will be described using a disk tray as an example.

  In a recording apparatus capable of transporting a disk tray, a guide (hereinafter referred to as a “tray guide”) for supplying the disk tray horizontally is provided on the front side of the apparatus (on the downstream side of the discharge roller). Note that this tray guide may be provided as a dedicated member as shown in Patent Document 1, or a medium receiving tray that receives plain paper or the like may have the function as shown in Patent Document 2.

  In the tray guide, the height position of the guide surface for guiding the disc tray is preferably the same as the top of the roller constituting the paper discharge means from the viewpoint of horizontally feeding the disc tray into the transport path. However, the following demands exist.

  For example, the paper discharge means is composed of a lower discharge drive roller and an upper discharge driven roller, and the upper discharge driven roller employs a jagged roller (spur) to prevent ink transfer. There are many cases. In many cases, the discharge driven roller is retracted upward when recording on the optical disk, since there is a risk that the data area of the optical disk may be damaged if the zigza roller contacts the printing surface (label surface) of the optical disk. Yes.

  On the other hand, as a mechanism for retracting the discharge driven roller upward, there is a mechanism in which a disc tray supported by a tray guide pushes up a frame member that supports the discharge driven roller. For example, in the case of the recording apparatus disclosed in Patent Document 2, a release member that comes into contact with the disk tray is swingably provided on a paper discharge frame Assy that supports the discharge driven roller, and the paper discharge frame Assy is provided via the release member. It is configured to push upward. With such a mechanism, there is no need for the user to perform the operation of retracting the discharge driven roller upward, or a driving source for retracting the discharge driven roller upward is unnecessary, which is advantageous.

  However, on the other hand, there is a problem that it is difficult to secure an amount for moving the discharge driven roller upward (hereinafter referred to as “release amount”). In order to solve such a problem, it is preferable that the position where the release member is in contact with the disc tray is lowered downward, that is, the discharge frame Assy is pushed up from the lower side as much as possible. Therefore, from the viewpoint of such a requirement, it is preferable that the height position where the release member and the disc tray come in contact is lowered from the top of the discharge driving roller.

  However, if the position where the release member and the disc tray are in contact with each other is lowered below the top of the discharge drive roller in order to secure the release amount, the release member that is not engaged with the transported medium is moved downstream from the discharge unit in the transport direction. This obstructs the conveyance path of the sheet sent to the side, which may hinder the discharge of the sheet. Further, in the recording apparatus disclosed in Patent Document 2, since the guide surface for guiding the disc tray exists below the release member, the height position where the release member and the disc tray are in contact cannot be lowered below the guide surface. .

  Therefore, the present invention has been made in view of such a situation, and the object of the present invention is to set the height at which the release member and the disc tray are in contact with each other without hindering the discharge of the paper sent from the discharge portion to the downstream side in the transport direction. An object of the present invention is to provide a recording apparatus that can be made lower.

In order to solve the above-described problem, a recording apparatus according to an aspect of the present invention includes an apparatus main body having a conveyance path through which a medium to be conveyed is conveyed, and a medium to be conveyed in a direction of discharging the medium to be conveyed to the outside of the apparatus main body. A first roller for feeding the medium, a feeding means configured to switch between a state in contact with the first roller from above and a state of being separated from the first roller; A guide section provided on the downstream side of the transport direction of the transport medium, and having a guide surface for guiding the transport medium supplied from the feed means toward the inside of the apparatus main body from the downstream side of the transport direction to the transport path; A first state in which the second roller is supported and the second roller is brought into contact with the first roller; and a transported medium supplied to the transport path using the guide surface The roller support portion that can be switched between the second state in which the second roller is separated from the first roller by being pushed up, and the roller support portion is swingably provided and does not engage with the medium to be transported. A release unit that is lowered so as to block a conveyance path of the medium to be conveyed in a state, and the release unit is arranged in the width direction of the medium to be conveyed, which is a direction intersecting the feeding direction of the medium to be conveyed. It is located in a region where a medium to be transported sent in the direction of discharging to the outside passes, and swinging in a direction to be pushed away by the medium to be transported sent in the direction of discharging to the outside of the apparatus main body is allowed, and from the feeding means Oscillation in the direction of being pushed away by the transported medium supplied from the downstream side in the feed direction toward the inside of the apparatus main body is restricted, and the feed means When the transported medium is supplied from the downstream side in the recording direction toward the inside of the apparatus main body, the roller support unit is moved from the first state to the second state via the release unit by the transported medium. The lower end portion of the release portion in a state in which the release portion is not in contact with the medium to be conveyed is below the guide surface in the height direction.
The recording apparatus according to the first aspect of the present invention includes an apparatus main body having a conveyance path through which a medium to be conveyed is conveyed, and a medium to be conveyed in a direction of discharging the medium to be conveyed to the outside of the apparatus main body.

The vertical direction, that is, the direction of gravity is shown.

  The overall configuration of the printer 10 will be outlined below with reference to FIGS. 1 and 2. The printer 10 includes an apparatus main body 12 and an operation panel unit 16 provided on a front surface 14 of the apparatus main body and used for user operation input. The operation panel unit 16 is configured to be able to rotate forward with respect to the front surface 14 of the apparatus main body 12 with the upper part thereof as a rotation axis. In the printer 10, when the operation panel unit 16 is rotated in front of the apparatus main body 12, the medium receiving tray 18 protrudes forward from the apparatus main body 12, and is a sheet (hereinafter referred to as “conveyed medium”). “Paper P”) is ready for recording (FIG. 2).

  Hereinafter, the components on the sheet conveyance path will be described in more detail with reference to FIG. The apparatus main body 12 includes a lower tray 19 for storing sheets, an upper tray 20 that is positioned above the lower tray 19 and that stores sheets, and includes a feeding unit 22. The conveying means 24, the recording means 26, and the feeding means 28 are provided. The lower tray 19 and the upper tray 20 are configured to be detachable from the apparatus main body 12 from the front side of the apparatus. The feeding unit 21 further includes a pickup roller 30 and a separating unit 36.

  Further, the upper tray 20 is driven by a motor (not shown) in the paper transport direction (FIG. 3, Y-axis direction), so that the end position, that is, the feedable position (see FIG. 3) and the end position are opposite to the paper transport direction. It is configured to be movable between a retracted position (not shown) displaced by a predetermined amount. In FIG. 3, the paper accommodated in the lower tray 19 is indicated by reference numeral P <b> 1, and the paper accommodated in the upper tray 20 is indicated by reference numeral P <b> 2 (hereinafter referred to as “ Paper P)). Note that the paper P is a further example of a sheet material that is an example of a transported medium.

  A pickup roller 30 that is rotationally driven by a motor (not shown) is provided above each tray. The pickup roller 30 is provided on a swing member 34 that swings around a swing shaft 32. When the upper tray 20 is in a feedable position, the pickup roller 30 rotates in contact with the uppermost sheet P2 accommodated in the upper tray 20 to move the uppermost sheet P2 to the upper stage side. Send out from the tray 20 to the feeding path.

  When the upper tray 20 is in the retracted position, the pickup roller 30 rotates in contact with the uppermost sheet P1 stored in the lower tray 19 so that the uppermost sheet P1 is moved to the lower tray 19. To the feeding route.

  Separating means 36 is provided at a position facing the leading edge of the paper P1 stored in the lower tray 19 and the leading edge of the paper P2 stored in the upper tray 20. The separating means 36 is in contact with the leading edge of the paper P fed out by the rotation of the pickup roller 30 from the lower tray 19 or the upper tray 20, and is conveyed downstream in the feeding path in a state where the paper P is in contact with the separating means 36. As a result, the uppermost sheet P and the subsequent sheets P are separated. Accordingly, the feeding unit 21 sends out a sheet material (paper P), which is an example of a transported medium, to the downstream side of the feeding path.

  The feeding unit 22 is provided on the downstream side of the feeding path of the separating unit 36. The feeding unit 22 includes a feeding driving roller 38 driven by a motor (not shown), a separation roller 40, and a feeding driven roller 42. The separation roller 40 is in contact with the feed driving roller 38 and again separates the paper P, and reliably feeds only the uppermost paper P to the downstream side of the feed path.

  Further, on the downstream side of the separation roller 40, a feeding driven roller 42 that is driven to rotate while sandwiching the paper P with the feeding driving roller 38 is provided. Further, on the downstream side of the feeding path of the feeding driven roller 42, the conveying means 24 is provided with a conveying driving roller 44 driven by a motor (not shown) and a conveying driven roller 46 that is pressed against the conveying driving roller and rotated. Is provided. The conveying means 24 feeds the paper P further downstream.

  A recording unit 26 is provided on the downstream side of the conveying unit 24. The recording means 26 includes a recording head 48 and a lower guide member 50 facing the recording head. The recording head 48 is provided at the bottom of the carriage 52 and faces the paper P. The carriage 52 is driven so as to reciprocate in the main scanning direction (the front and back direction in FIG. 3, that is, the X-axis direction) by a drive motor (not shown).

  The lower guide member 50 supports the paper P and defines the distance between the paper P and the recording head 48. Further, on the downstream side of the lower guide member 50, a feeding unit 28 that feeds the recorded paper P is provided. The feeding means 28 includes a first roller 54 that is driven by a driving source (not shown), and a second roller 56 that rotates in contact with the first roller.

  The paper P on which recording has been performed by the recording unit 26 is held between the first roller 54 and the second roller 56 and is discharged to the medium receiving tray 18 provided on the front surface 14 side of the apparatus main body 12. The medium receiving tray 18 is displaced in a direction protruding to the outside of the apparatus main body 12 as the operation panel portion 16 is rotated with respect to the apparatus main body 12, that is, pulled out along the Y-axis direction or pulled inside the apparatus main body 12. It is configured to be able to switch to a state of being displaced in the direction to be moved.

  Here, the components of the medium receiving tray 18 will be described in detail with reference to FIGS. 4, 5A, and 5B. The medium receiving tray 18 includes a medium receiving surface 58 extending from the upstream side in the feed direction (Y direction in FIG. 4) toward the downstream side (Y direction in FIG. 4), and a pair of raised portions 60 and 60. Yes. A pair of racks 62 and 62 extending from the upstream side to the downstream side in the feeding direction are provided at both ends of the medium receiving surface 58 in the paper width direction. The rack 62 meshes with pinion gears 68 and 68 provided in a drive mechanism 66 driven by a motor 64.

  The medium receiving tray 18 projects from the state accommodated in the apparatus main body 12 along the feeding direction (Y-axis direction) to the outside of the apparatus main body 12 by the driving force of the motor 64 via the drive mechanism 66. It is displaced, or it is displaced from a state of projecting outside the apparatus main body 12 to a state accommodated in the apparatus main body 12. The drive mechanism 66 is provided with detectors 70 and 70 that detect whether the medium receiving tray 18 is housed in the apparatus main body 12 or protrudes to the outside of the apparatus main body 12.

  The raised portions 60 are provided on the downstream side of the medium receiving surface 58 in the feeding direction and in the region supporting the paper P so as to face each other with a gap in the paper width direction, and are formed to rise in the apparatus height direction. ing. On the upstream side of the protruding portion 60 in the feeding direction, an inclined guide surface 72 is provided to guide the leading edge of the paper P sent out by the feeding means 28 so as to get over the protruding portion 60. The inclined guide surface 72 corresponds to the paper P having a paper width larger than the distance between the raised portions 60 and 60.

  Further, an inclined guide surface that guides the leading edge of the paper P sent out by the feeding means 28 between the one raised portion 60 and the other raised portion 60 on the downstream side in the feed direction from the inclined guide surface 72. 74 is provided. The inclined guide surface 74 corresponds to the paper P having a paper width smaller than the distance between the raised portions 60 and 60.

  In addition, a guide surface 78 for guiding a disk tray 76 (described later) supplied from the downstream of the feeding unit 28 toward the inside of the apparatus main body 12 to the conveyance path is provided on the upper portion of the raised portion 60. . That is, the raised portion 60 functions as a tray guide portion that guides the disc tray 76 from the downstream side in the feed direction to the upstream side. For this reason, the medium receiving tray 18 not only receives the paper P, but also serves as a guide portion 79 (see FIG. 3) of the disc tray 76.

Next, a detailed description will be given of a case where a disk tray 76, which is an example of a medium to be transported, is supplied into the apparatus main body 12 from the downstream side in the feeding direction of the feeding means 28 with reference to FIGS.
In FIG. 7, the release portion 92 is not shown in order to show the relationship between the disc tray 76 and a guide surface 78 (described later). In the example of FIG. 6, a disk tray 76 on which the optical disk D, which is an example of a transported medium, is placed. The disc tray 76 forms a plate-like body and is formed of, for example, a resin material so that the optical disc D can be set at the center. As a preparatory operation, the user operates the operation panel unit 16 provided on the front surface 14 of the apparatus main body 12 to switch the recording target from the paper P stored in the lower tray 19 or the upper tray 20 to the optical disc D.

  In response to this operation, a control unit (not shown) provided in the apparatus main body 12 causes the detector 70 to detect the position of the medium receiving tray 18. When the medium receiving tray 18 protrudes outward from the apparatus main body 12, the control unit drives the drive mechanism 66 by the motor 64 to displace the medium receiving tray 18 so as to be accommodated inside the apparatus main body 12. Thereafter, the user inserts the disc tray 76 along the guide surface 78 of the medium receiving tray 18 from the front of the apparatus main body 12.

When the leading end of the disc tray 76 is inserted to a predetermined position, the disc tray 76 is nipped between the first roller 54 and a driven roller 80 described later (FIGS. 8 and 13). In this state, the control unit drives the first roller 54 in the reverse direction. As a result, the disc tray 76 is pulled into the apparatus, recording is performed on the optical disc D set in the disc tray 76, and the disc tray 76 is discharged by the forward rotation of the first roller 54.
As described above, the printer 10 according to the present embodiment is configured to be able to transport not only a highly flexible medium to be transported such as plain paper but also a disk tray 76 having a low flexibility as a medium to be transported.

  In addition, the upper part of the protruding part 60 is provided with the hook-like part 82 (FIG. 4, FIG. 5 (A) and FIG. 5 (B)). The hook-shaped portion 82 extends in the feed direction so as to face a part of the guide surface 78. A space 84 between the bowl-shaped portion 82 and the guide surface 78 extends along the feeding direction, and receives the end of the disc tray 76 in the sheet width direction (FIG. 6). The bowl-shaped portion 82 is guided by the guide surface 78 and restricts the disc tray 76 conveyed through the space 84 from floating from the guide surface 78.

  Hereinafter, the components of the feeding means 28 will be described in more detail with reference to FIGS. 9 to 13. The first roller 54 includes a roller shaft 86 and a first roller unit 88. The roller shaft 86 is connected to a drive source (not shown) and extends in the paper width direction (the front / back direction in FIG. 9, that is, the X-axis direction). A plurality of first roller portions 88 are provided on the outer peripheral surface of the roller shaft 86 at appropriate intervals along the paper width direction (see FIG. 10).

  Above the first roller 54, a roller support 90 extending in the paper width direction is provided. The roller support portion 90 is provided with a plurality of second rollers 56 at positions corresponding to the first roller portion 88 along the paper width direction (see FIG. 9). In addition, the roller support unit 90 includes a “first state” in which the second roller 56 is brought into contact with the first roller 54 from above, and a “second state” in which the second roller 56 is separated from the first roller 54. Are displaceable in the height direction of the apparatus so that they can be switched.

  Furthermore, a release unit 92 is provided on the roller support unit 90 on the downstream side in the sheet feeding direction from the second roller 56 (the Y direction in FIG. 9). The release unit 92 includes a release swing member 94 and a driven roller 80. One end of the release swing member 94 is supported by the roller support portion 90 so as to freely swing. Further, the other end of the release swinging member rotatably supports the driven roller 80. For this reason, when the external force is not applied, the release unit 92 is suspended by its own weight, and when the external force is applied, the release unit 92 swings in a direction in which the external force is applied (however, swinging in a predetermined direction is restricted). Will be described later.)

  A plurality of release units 92 are provided on the roller support unit 90 at intervals in the sheet width direction (see FIG. 11). The release part 92 hangs downward from the roller support part 90 so as to block the transport path of the transported medium when not engaged with the transported medium (see FIG. 9). At this time, the lower end of the driven roller 80 supported by the other end of the release rocking member 94, that is, the release portion 92, is positioned below the top of the first roller 54 in the apparatus height direction.

  Further, the roller support portion 90 is provided with a restriction portion 96 that restricts the swing of the release portion between the second roller 56 and the release portion 92 in the feed direction. The release part 92 is pushed away by the paper P when the paper P is sent to the downstream side in the feed direction (Y direction in FIG. 12) by the feeding means 28, and rotates downstream in the feed direction with respect to the roller support part 90 (see FIG. 12). (See FIG. 12). For this reason, the release unit 92 does not hinder the conveyance of the paper P from the feeding unit 28 to the downstream side in the feeding direction. Further, when the disc tray 76 is pushed from the downstream side in the feed direction to the feed means 28, that is, the apparatus main body 12, the release unit 92 rotates upstream in the feed direction (see FIGS. 8 and 13). ).

  At this time, the rotation of the release part 92 is restricted by the restriction part 96 during the turning to the upstream side in the feed direction. Further, when the disc tray 76 is pushed upstream in the feed direction so as to push the release part 92 whose rotation is restricted to the upstream side in the feed direction, the release part 92 displaces the roller support part 90 upward. Accordingly, the roller support unit 90 separates the second roller 56 in contact with the first roller 54 from the first roller 54.

  Here, the second roller 56 is a toothed roller (spur) having teeth on the outer periphery. Therefore, if the second roller 56 is in contact with the label surface of the optical disc D, there is a risk of damaging the data area of the optical disc D. When the disc tray 76 is inserted as described above, the disc tray 76 retracts the roller support portion 90, that is, the second roller 56 through the release portion 92, so that the optical disc D set on the disc tray 76 is damaged. There is no fear of giving.

  Next, the guide surface 78 provided on the raised portion 60 formed on the medium receiving tray 18 will be further described. 5A and 5B, the guide surface 78 is formed from the downstream end of the raised portion 60 in the feed direction toward the upstream end of the raised portion 60 in the feed direction. Has been. The guide surface 78 has a width capable of guiding the disc tray 76. Further, at the upstream end of the guide surface 78 in the feeding direction, a convex portion 98 is formed so as to protrude upward from the guide surface 78 and functions as an “invitation portion” so as to protrude from the guide surface 78. ing. The convex portion 98 is formed in an inclined shape so as to guide the leading end 100 of the disc tray 76 from the downstream side in the feed direction to the upstream side.

  Here, with reference to FIG. 9 again, the relationship between the feeding means 28 and the medium receiving tray 18 will be described. In a state where the medium receiving tray 18 is housed in the apparatus main body 12, the medium receiving surface 58 is positioned below the height position at which the feeding means 28 feeds the paper P. The guide surface 78 provided on the raised portion 60 is located below the top of the first roller 54 of the feeding means 28 in the apparatus height direction.

  Further, the guide surface 78 is located above the lower end of the release unit 92 in the apparatus height direction in a state where the release unit 92 is not engaged with the transported medium. Referring to FIG. 10 again, the release portion 92 is located between the guide surfaces 78 and 78 formed on the raised portions 60 and 60 in the paper width direction, and is out of the region where the guide surface 78 is formed. Placed in position. The release unit 92 is located in the area of the medium to be transported in the paper width direction. Since no guide surface exists below the release portion 92, the lower end of the release portion 92 can be positioned below the guide surface 78. Moreover, the release part 92 is located in the area | region in which the guide surface 78 was formed in the feed direction.

  Next, the leading end 100 of the disc tray 76 inserted into the space 84 between the guide surface 78 and the bowl-shaped portion 82 is along the guide surface 78 from the downstream side in the feed direction (the Y direction in FIG. 7) to the upstream side (see FIG. 7). 7Y direction). Thereafter, the leading end 100 of the disc tray 76 rides on a convex portion 98 provided at the upstream end of the guide surface 78, proceeds upstream in the feed direction while being guided upward, and reaches the top of the first roller 54. To do. The disc tray 76 is separated from the convex portion 98 and is supported by the top portion of the first roller 54 and the support portion 102 of the medium receiving tray 18 (see FIG. 8).

  Here, the support portion 102 is provided so as to slightly protrude from the guide surface 78 when the guide surface 78 is viewed from the side (see FIGS. 5A and 5B). Even when the height of the guide surface 78 is below the top of the first roller 54, the disc tray 76 is supported by the first roller 54 and the support 102 so that the horizontal posture is maintained. It is supposed to be done.

  In the process in which the leading end 100 of the disc tray 76 reaches the top of the first roller 54, the disc tray 76 has a region where the leading end 100 is formed in the feeding direction and below the guiding surface 78 in the height direction. The lower end of the release unit 92, that is, the driven roller 80 is in contact with the position. The release unit 92 rotates upstream in the feed direction while the driven roller 80 rotates with respect to the disc tray 76. Then, the release part 92 comes into contact with the restriction part 96 of the roller support part 90, and the restriction part 96 restricts the rotation to the upstream side in the feed direction. Therefore, the release unit 92 is displaced upward by the disc tray 76. As a result, the roller support unit 90 is displaced upward and switches from the first state in which the second roller 56 is in contact with the first roller 54 to the second state in which the second roller is separated from the first roller 54. .

  Further, the displacement amount of the second roller 56, that is, the displacement amount (release amount) h in the apparatus height direction of the release portion 92 is set to be larger than the thickness t of the optical disc D set on the disc tray 76. Yes. For this reason, the recording surface of the optical disc D passing between the top of the first roller 54 and the second roller 56 does not contact the second roller 56, and the recording surface of the optical disc D before and after recording is performed. There is little possibility of hurting.

  Referring again to FIG. 13, the convex portion 98 provided on the guide surface 78 invites the leading end 100 of the disc tray 76 that is fed from the downstream side in the feeding direction to the upstream side, and the leading end of the first roller 54. Get on top. If the convex surface 98 is not provided on the guide surface 78, the height position of the guide surface 78 is located below the top of the first roller 54. It will collide with the outer peripheral surface, and the insertability when the disc tray 76 is inserted will be lowered (feeling of being caught).

  However, in the present invention, by providing the convex portion 98, the guide surface 78 can be made lower than the height of the top portion of the first roller 54, so that the first roller 54 is disposed at the tip 100 of the disc tray 76 as described above. Since collision with the outer peripheral surface can be prevented or the degree of collision can be reduced, the insertion property when the disc tray 76 is inserted can be improved.

  As a result, the height position of the guide surface 78 can be made lower than the top of the first roller 54, so that the push-up amount (release amount) when the disk tray 76 pushes up the roller support portion 90 via the release portion 92 is sufficiently large. That is, the second roller 56 can be sufficiently separated from the first roller 54.

  Referring again to FIG. 4, the guide surface 78 functioning as a tray guide portion is provided on the raised portion 60 formed on the medium receiving tray 18. If the medium receiving tray 18 and the guide surface 78 are configured separately, the number of components constituting them increases, and the tray guide portion (guide surface 78) is stored inside the apparatus main body 12 separately from the medium receiving tray 18. Space is needed. Further, in the case of such a configuration, when recording is performed on a low-flexibility transported medium such as an optical disk or board, the tray guide unit is set on the downstream side in the feeding direction of the feeding unit 28 or the tray guide unit It is necessary to perform a preparation operation such as switching the posture by the user's operation, and the preparation operation for recording execution becomes complicated.

  However, according to the present invention, the guide surface 78 is provided on the raised portion 60 formed on the medium receiving tray 18 so that the medium receiving tray 18 receives the paper P discharged by the feeding means 28, as well as the disk tray. 76 guide functions can be provided. In addition, since the medium receiving tray 18 and the guide surface 78 functioning as a tray guide portion can be formed from a single member, the number of parts can be reduced and the cost can be reduced.

  Further, the guide surface 78 constitutes a transport path for the disc tray 76 in a state in which the medium receiving tray 18 is accommodated in the apparatus main body 12, so that an extra storage space for the tray guide portion is required in the apparatus main body 12. And not. Further, in the present invention, the user only has to insert the disc tray 76 along the guide surface 78 toward the inside of the apparatus main body 12 when performing recording of a low-flexibility transported medium such as an optical disc or board. The operability at the time of recording on a transported medium having low flexibility such as an optical disk or board is improved.

  Further, since the guide surface 78 is provided on the raised portions 60 formed on both sides of the medium receiving surface 58 in the paper width direction as described above, the guide surface 78 is higher than the medium receiving surface 58 in the height direction. Located above. For this reason, in the present invention, when the release portion 92 is disposed between the guide surface 78 in the sheet width direction, the lower end of the release portion 92 can be positioned below the guide surface 78. Therefore, this invention can increase the release amount of the roller support part 90 (2nd roller 56).

  Further, referring to FIGS. 9 and 13 again, the release portion 92 of the present embodiment does not include an urging means, and therefore, the release portion 92 is transported by its own weight when not being engaged with the member to be transported. It will be in the state which hung down so that a route might be interrupted. For this reason, the release part 92 can be easily swung with a light force. For this reason, when the user inserts the disc tray 76 along the guide surface 78 toward the inside of the apparatus main body 12 and pushes up the roller support portion 90, the user can smoothly operate without feeling uncomfortable and the operability is improved. . In addition, it does not hinder the discharge of cut sheets and the like.

  Further, referring to FIG. 9 (the drawing in which the position of the release part is changed), in the present invention, a guide surface 78 is formed in the feed direction at the position where the front end 100 of the disc tray 76 and the lower end of the release part 92, that is, the driven roller 80 are in contact. It is possible to make the area lower than the guide surface 78 in the height direction.

  If the position where the leading end 100 of the disc tray 76 and the driven roller 80 contact in the feeding direction is upstream in the feeding direction from the region where the guide surface 78 is formed, the leading end 100 of the disc tray 76 is supported by the guide surface 78. Since it is not done, it sinks downward by the weight of the release part 92 acting on the tip 100. If the disc tray 76 is advanced to the upstream side in the feed direction, the tip 100 of the disc tray 76 collides with the outer peripheral surface of the first roller 54.

  However, in the present invention, the position where the tip 100 of the disc tray 76 and the driven roller 80 are in contact with each other is the region where the guide surface 78 is formed in the feed direction. Supports the front end 100 of the disc tray 76, and the front end 100 is less likely to sink downward.

  In the present invention, not only the height of the guide surface 78 is set lower than the top of the first roller 54 as described above, but also the lower end of the release portion 92, more specifically, the disc tray 76 at the release portion 92. Since the lower surface (lower outer peripheral surface) of the driven roller 80 that forms a contact position in contact with the lower surface of the driven roller 80 is below the guide surface 78 in the height direction (in a state where it does not contact the disk tray 76), the disk tray 76 is released from the release portion 92. The push-up amount (release amount) at the time of pushing up the roller support part 90 via the can be increased. In addition, even if the length of the release swing member 94 is increased in order to secure the release amount, it is not necessary to set the swing shaft of the release swing member 94 at a high position. Increase can be suppressed.

  In summary, the printer 10 of the present embodiment is configured such that when the disc tray 76 is supplied from the downstream side in the feed direction to the inside of the apparatus main body 12 from the feed unit 28, the disc tray 76 passes the release unit 92 via the release unit 92. The roller support portion 90 is configured to be pushed up from the first state toward the second state.

  The release portion 92 of the present embodiment is allowed to swing in the direction of being pushed away by the paper P that is sent in the direction of discharging to the outside of the apparatus main body 12, and from the feed unit 28 toward the inside of the apparatus main body 12 from the downstream side in the feed direction. Oscillation in the direction of being pushed away by the supplied disc tray 76 is restricted. Further, the lower end portion of the release portion 92, more specifically, the lower surface (lower outer peripheral surface) of the driven roller 80 that forms a contact position in contact with the disc tray 76 in the release portion 92 is the feed direction of the paper P and the disc tray 76. Are provided in a direction intersecting with the feeding direction of the paper P and the disc tray 76 and are located in a region through which the paper P and the disc tray 76 pass.

  Further, in the present embodiment, the lower end portion of the release portion 92 is out of the region where the guide surface 78 is formed in the direction intersecting the feeding direction of the paper P and the disc tray 76 and is not in contact with the disc tray 76. Thus, it is located below the guide surface 78 in the height direction. In addition, the lower end portion of the release portion 92 is positioned below the contact position between the first roller 88 and the second roller 56 in the height direction without contacting the disc tray 76.

  Further, the lower end portion of the release portion 92 is located in the region where the guide surface 78 is formed in the feeding direction of the paper P and the disc tray 76. Note that the lower end portion of the release portion 92 is constituted by a driven roller 80 that rotates in contact with the disc tray 76. Furthermore, the guide surface 78 is located below the top of the first roller 54 in the height direction.
