Here, the liquid ejecting apparatus refers to an ink jet recording apparatus, a copying machine, a facsimile, or the like that performs recording on a recording material by ejecting ink from a recording head as a liquid ejecting head to a recording material such as recording paper. In addition to the recording apparatus, instead of ink, a liquid corresponding to a specific application is ejected from the liquid ejecting head corresponding to the recording head to the ejected material corresponding to the recording material, and the liquid is ejected to the ejected material. Used to include the device to be attached. In addition to the recording head described above, the liquid ejecting head includes a color material ejecting head used for manufacturing a color filter such as a liquid crystal display, an electrode material used for forming an electrode such as an organic EL display and a surface emitting display (FED) ( Examples thereof include a conductive paste) ejection head, a bio-organic matter ejection head used for biochip manufacturing, and a sample ejection head that ejects a sample as a precision pipette.
In the present specification, “first medium” refers to “non-rigid medium” as an example, and “second medium” refers to “rigid medium” as an example.
Here, the “non-rigid medium” refers to a flexible medium such as paper or an OHP sheet. The “rigid medium” refers to a medium having little flexibility such as a dedicated CD-R tray with a CD-R attached.

Conventionally, an ink jet recording apparatus that records a sheet as an example of a non-rigid medium performs recording on a label surface of an information recording medium such as a CD-R as an example of a rigid medium (for example, Patent Document 1 and 2). The sheets are stacked on a hopper provided on the upstream side of the transport path, and only the uppermost sheet among the stacked sheets by the swing of the hopper is picked up by a side-view D-type feeding roller. Yes. Then, the sheet is fed from the feed roller to the pair of transport rollers on the downstream side in the transport direction, and is transported to the recording unit while being sandwiched between the pair of transport rollers. Further, the sheet is recorded by the recording unit and discharged to the discharge stacker by the discharge roller pair on the downstream side in the transport direction.
Usually, in order to place the recorded paper on the discharge stacker, the discharge stacker is disposed below the pair of discharge rollers.

At this time, in the non-rigid paper conveyance path, the feeding roller and the conveyance roller are not provided in a straight line for the purpose of separating the paper that is likely to be fed in an overlapping manner. Therefore, the rigid CD-R and CD-R tray cannot be set in the hopper like the paper.

  Therefore, the conveyance path downstream in the conveyance direction from the conveyance roller pair is provided in a straight line, the CD-R tray is inserted from the discharge roller pair provided downstream in the sheet conveyance direction, and the discharge roller pair is driven in reverse. The CD-R tray was moved to a position where the upstream recording head could record on the CD-R label surface. Then, recording is performed on the label surface of the CD-R while moving from the recording start position to the downstream side.

  At this time, it is necessary to set the CD-R tray on the discharge roller pair. In the prior art, the discharge stacker provided below the discharge roller pair is moved upward to guide the CD-R tray to the discharge roller pair. In other words, when recording the label surface of the CD-R, the discharge stacker is moved to the height of the linear conveyance path so that the discharge stacker guides the CD-R tray to the discharge roller pair, and after recording. The CD-R tray is configured to serve also as a CD-R tray discharge stacker that receives the discharged CD-R tray.

  Thereafter, the ejection drive roller 20a is driven to rotate in the forward direction, and the recording head 13 is scanned in the main scanning direction X while the CD-R tray Q is moved downstream in the transport direction, and recording is performed on the CD-R label. To do. When the recording is completed, the discharge driving roller 20a and the second discharge driven rollers 503 and 503 cooperate to discharge the CD-R tray Q to the downstream side in the transport direction. At this time, the upstream end in the transport direction of the CD-R tray Q is disengaged from the nip between the ejection drive roller 20a and the second ejection driven rollers 503 and 503, so that the CD-R tray Q is again in the CD as shown in FIG. -Stops at a position where the CD-R tray Q protrudes further than a position where a part of the CD-R tray Q protrudes from the R tray guide opening 522.

In the CD-R recording mode, the first discharge stacker 500 provided with the CD-R tray guide opening 522 moves to the downstream side in the transport direction, so that the user can easily set the CD-R tray Q. . Further, after recording, the user can easily take out the CD-R tray Q. At this time, since a part of the CD-R tray Q protrudes from the CD-R tray guide opening 522, the CD-R tray Q can be taken out more easily.
Further, since the first discharge stacker 500 moves downstream in the transport direction, it is possible to support the center of gravity of the CD-R tray Q. Therefore, the posture of the CD-R tray Q can be stabilized.

[About PG switching and recording mode switching]

If there is a change in the thickness of the paper P or a change from the paper recording mode for recording the paper P to the CD-R recording mode for recording the CD-R label surface, the cam is driven by a PG adjustment motor (second motor) (not shown). The shaft 302 rotates. At this time, the carriage guide shaft 12 is eccentric with respect to the cam shaft 302. Accordingly, the recording unit gap adjusting device 300 can adjust a so-called platen gap or paper gap (hereinafter referred to as PG), which is the interval between the recording head 13 and the platen 28, by the rotation of the cam shaft 302. .

  Further, the cam shaft 302 is provided with a PG adjustment cam portion 301. A lever abutting portion 303 of a lever member 304 urged clockwise with a lever shaft 305 as a fulcrum by a torsion coil spring (not shown) is provided so as to abut and press against the PG adjustment cam portion 301. ing. At this time, the PG adjustment is performed by rotating the cam shaft 302 within a range in which the arc portion 301 a of the PG adjustment cam portion 301 contacts the lever contact portion 303. Then, when switching between the paper recording mode and the CD-R recording mode, the cam shaft 302 is rotated so that the chord portion 301b of the PG adjustment cam portion 301 faces the lever contact portion 303, which will be described later. The power transmission switching device 400 is configured to be switched.

Then, both the first planetary gear 423 and the second planetary gear 424 are separated from the first gear 211. Therefore, the power of the sun gear 426 is not transmitted to the first gear 211.

  Here, the planetary gear holder unit 420 may be configured to rotate in the same direction as the sun gear 426 by a frictional resistance generated between the planetary gear holder unit 420 and the rotation fulcrum shaft 425. Further, it may be configured to rotate in the same direction as the sun gear 426 by a frictional resistance generated between the first planetary gear 423 and the second planetary gear 424 and the planetary gear holder portion 420.

As shown in FIG. 8, when the camshaft 302 is rotated clockwise and the string portion 301b is opposed to the lever contact portion 303, the lever member 304 is rotated clockwise. Then, the slide bar 430 moves to the left side in the figure. Further, as the slide bar 430 moves to the left side, the lock lever 410 moves, so that the planetary gear holder portion 420 is released from the restriction of the lock lever 410. Therefore, the planetary gear holder 420 generates a force that rotates in the rotating direction of the sun gear 426. At this time, the discharge drive roller 20a is rotated in the counterclockwise direction in the figure, which is the reverse direction in which the paper P can be moved upstream. The sun gear 426 is provided so as to rotate in the same direction as the discharge drive roller 20a. Accordingly, the planetary gear holder portion 420 rotates counterclockwise about the rotation fulcrum shaft 425 of the sun gear 426 so that the second planetary gear 424 contacts the first gear 211. That is, the power of the sun gear 426 is transmitted to the first gear 211 via the second planetary gear 424. At this time, since the second planetary gear 424 contacts the first gear 211 while rotating clockwise, the first gear 211 rotates counterclockwise.

Then, as described above, the planetary gear holder portion 420 is released from the restriction of the lock lever 410.
At this time, as shown in FIG. 9, the discharge drive roller 20a is rotated in the clockwise direction in the figure, which is the normal rotation direction in which the paper P can be moved downstream. Therefore, as described above, the sun gear 426 also rotates in the clockwise direction, which is the same direction as the discharge drive roller 20a. As described above, the sun gear 426 rotates the planetary gear holder 420 in the clockwise direction.

  The planetary gear holder 420 rotates clockwise, and the first planetary gear 423 circumscribes the first gear 211. Accordingly, the power of the sun gear 426 is transmitted to the first gear 211 via the first planetary gear 423. At this time, since the sun gear 426 rotates clockwise, the first planetary gear 423 rotates counterclockwise, and the first gear 211 rotates clockwise. As the first gear 211 rotates, from the upstream side to the downstream side in the power transmission direction, the second gear 212 is counterclockwise, the third gear 213 and the fourth gear 214 are clockwise, and the fifth gear 215 is In the counterclockwise direction, the sixth gear 216 and the seventh gear 217 rotate in the clockwise direction, and the eighth gear 218 and the pinion 219 rotate in the counterclockwise direction.

Racks 227 and 227 are provided on one surface of the pair of sixth groove portions 226 and 226, and are configured to mesh with the pair of pinions 219 and 219 described above.

  The second discharge stacker 600 includes a second placement portion 610 that rotates around the cover shaft 601 and places the discharged paper P in cooperation with the first discharge stacker 500 at the first position. Yes. The second discharge stacker 600 is provided so as to rotate around the cover shaft 601 and close the mounting opening 260 in a state where recording is not executed. In other words, the second discharge stacker 600 is provided so as to also serve as a cover case. When the second discharge stacker 600 is opened, the posture of the second discharge stacker 600 is restricted by the cover restricting portion 250 provided on the base portion 220.

The discharge frame portion 800 is engaged with a pair of fourth protrusions 801 and 801 engaged and guided by the pair of fourth groove portions 224 and 224 of the base portion 220 and the pair of fifth groove portions 225 and 225 of the base portion 220.

The connecting arm portion 700 includes a pair of third protrusions 701 and 701 that are engaged and guided by the pair of third groove portions 223 and 223 of the first discharge stacker 500 at one end, and the other end is a first portion of the discharge frame portion 800. The four protrusions 801 are provided so as to be rotatably connected to the downstream side in the transport direction.

  In the first position, the position of the downstream end of the first discharge stacker 500 in the transport direction is set higher than the position of the upstream end of the second discharge stacker 600 in the transport direction. Therefore, in the paper recording mode, the leading edge of the paper P discharged from the discharge roller is at the level difference between the first placement portion 510 of the first discharge stacker 500 and the second placement portion 610 of the second discharge stacker 600. There is no risk of getting caught.

The first position is the so-called home position of the first discharge stacker 500, and the home position detector 230 provided on the base 220 is configured to be in contact with the first discharge stacker 500 for detection. Yes. The driving amount of the first motor when the first discharge stacker 500 moves from the first position to the second position is a predetermined number of steps after the first discharge stacker 500 is separated from the home position detector 230. It is controlled to stop at. On the other hand, the driving amount of the first motor when the first discharge stacker 500 moves from the second position to the first position is controlled so that the first discharge stacker 500 stops in contact with the home position detector 230. Has been.
In the following description, the third protrusion, the fourth protrusion, the fifth protrusion, the third groove part, the fourth groove part, and the fifth groove part provided in pairs in the main scanning direction have the same shape on the left and right and are synchronized. Therefore, only one side will be described, and the other side will not be described.

As shown in FIG. 11, when the pinion 219 rotates clockwise from the state shown in FIG. 10, power is transmitted to the rack 227 of the first discharge stacker 500. At this time, since the position of the pinion 219 is fixed to the base portion side, the pinion 219 moves downward through the sixth groove portion 226 provided with the rack 227 to move the first discharge stacker 500 upward. To do. That is, a force to move upward acts on the first discharge stacker 500. Then, the first discharge stacker 500 is inclined so that the downstream end in the transport direction rises with the first protrusion 501 on the upstream side in the transport direction as a fulcrum. At this time, the second protrusion 504 of the first discharge stacker 500 moves slightly upward in the second groove of the base body 220.
Further, when the downstream end of the first discharge stacker 500 rises, the first discharge stacker 500 moves away from the home position detector 230, so that the count of the number of steps of the motor is started.

  As shown in FIG. 12, when the pinion 219 further rotates clockwise from the state shown in FIG. 11, the pinion 219 attempts to move the first discharge stacker 500 further upward via the rack 227. Accordingly, the first discharge stacker 500 is inclined so that the downstream end in the transport direction further rises with the first protrusion 501 as a fulcrum. The lower end of the downstream end of the first discharge stacker 500 in the transport direction is higher than the upper end of the upstream end of the second discharge stacker 600 in the transport direction.

  As shown in FIG. 13, when the pinion 219 further rotates clockwise from the state shown in FIG. 12, the pinion 219 tends to move along the sixth groove 226 upstream in the transport direction. That is, the pinion 219 attempts to move the first discharge stacker 500 to the downstream side in the transport direction via the rack 227. Therefore, the first discharge stacker 500 is guided by the engagement between the first protrusion 501 and the first groove 221 and is guided by the engagement between the second protrusion 504 and the second groove 222 while being guided in the transport direction. Move downstream. At this time, the inclination, that is, the posture of the first discharge stacker 500 is regulated by the engagement between the first protrusion 501 and the first groove 221 and the engagement between the second protrusion 504 and the second groove 222. Therefore, the downstream end remains in the raised posture. Accordingly, the first discharge stacker 500 can move downstream in the transport direction so that the position of the downstream end of the first discharge stacker 500 in the transport direction is above the upstream end of the second discharge stacker 600.

  As shown in FIG. 14, when the pinion 219 further rotates clockwise from the state shown in FIG. 13, the pinion 219 tries to move the first discharge stacker 500 further downstream in the transport direction via the rack 227. . Accordingly, the first discharge stacker 500 is guided by the engagement between the first protrusion 501 and the first groove 221 and further conveyed while being guided by the engagement between the second protrusion 504 and the second groove 222. Move downstream in the direction. At this time, the third projecting portion 701 of the connecting arm portion 700 moves the third groove portion 223 of the first discharge stacker 500 to the upstream side in the transport direction and hits the upstream end of the third groove portion 223.

As shown in FIG. 15, when the pinion 219 further rotates clockwise from the state shown in FIG. 14, the first discharge stacker 500 further moves downstream in the transport direction. At this time, since the third protrusion 701 of the connecting arm portion 700 is in contact with the upstream end in the transport direction of the third groove portion 223 of the first discharge stacker 500, the first discharge stacker 500 is interposed via the connecting arm portion 700. Thus, the discharge frame portion 800 is moved downstream in the conveyance direction against the biasing force of the torsion coil spring described above.
At this time, the discharge frame portion 800 is guided by the engagement of the fourth protrusion 801 and the fourth groove portion 224 and the engagement of the fifth protrusion 802 and the fifth groove portion 225, and on the downstream side in the transport direction and above Move to. As the discharge frame portion 800 moves, the first discharge driven rollers 20b, 20b,... Provided in the discharge frame portion 800 are separated from the discharge drive roller 20a.
As the discharge frame portion 800 moves, the discharge auxiliary driven rollers 22, 22,... (See FIG. 3) also move the first discharge driven rollers 20b, 20b,. Has been.

  Further, due to the biasing force of the torsion coil spring described above, a force acts so that the third protrusion 701 of the connecting arm 700 pulls the upstream end of the third groove 223 of the first discharge stacker 500 upstream. Accordingly, a force is generated in the first discharge stacker 500 to rotate counterclockwise around a position where the rack 227 meshes with the pinion 219. The first protrusion 501 and the second protrusion 504 that are located on the opposite side of the third protrusion 701 with respect to the fulcrum by the force to rotate in the counterclockwise direction are the first groove 221 and It is pressed against the lower surface of the second groove 222. Accordingly, the posture of the first discharge stacker 500 can be further stabilized during movement.

  As shown in FIG. 16, when the pinion 219 further rotates clockwise from the state shown in FIG. 15, the first discharge stacker 500 further moves downstream in the transport direction. Then, the first discharge stacker 500 moves downstream in the transport direction, and the first discharge stacker 500 moves the discharge frame portion 800 through the connecting arm portion 700 against the biasing force of the torsion coil spring described above. Further, it is moved downstream in the transport direction.

  As shown in FIG. 17, when the pinion 219 further rotates clockwise from the state shown in FIG. 16, the pinion 219 attempts to move downward along the sixth groove portion 226. That is, the pinion 219 tries to move the first discharge stacker 500 upward via the rack 227. At this time, due to the biasing force of the torsion coil spring described above, a force is generated in the first discharge stacker 500 so as to rotate counterclockwise around a position engaging with the pinion 219 in the rack 227. Accordingly, when the pinion 219 rotates in the clockwise direction, the first discharge stacker 500 tilts so that the downstream end of the first discharge stacker 500 further rises with the first protrusion 501 as a fulcrum. Then, the contact surface 520 provided above the downstream side in the transport direction of the first discharge stacker 500 contacts the attitude regulating unit 228 of the base body 220.

  In a state where the contact surface 520 is in contact with the attitude regulating portion 228, the place where the third protrusion 701 and the third groove 223, which are the places where the biasing force of the torsion coil spring acts, is in the rack 227. It is located between a portion meshing with the pinion 219 and a portion in contact with the attitude regulating portion 228 on the contact surface 520. Therefore, the posture restricting portion 228 causes the contact surface to rotate in the counterclockwise direction with the urging force of the torsion coil spring as described above rotating about the position where the first discharge stacker 500 is engaged with the pinion 219 in the rack 227. It can be regulated by contacting with 520.

Further, when the pinion 219 is rotated in the clockwise direction, the movement of the first discharge stacker 500 on the downstream side in the conveyance direction is restricted by the attitude restriction unit 228, so that the first discharge stacker 500 has the downstream in the conveyance direction as a fulcrum. Move to lift the upstream side upward. At this time, the contact surface 520 contacts the posture restricting portion 228, and at the same time, the first discharge stacker 500 is restricted from rotating counterclockwise around the position where the rack 227 is engaged with the pinion 219. The first protrusion 501 and the second protrusion 504 are released from being pressed against the lower surfaces of the first groove 221 and the second groove 222, respectively. Accordingly, the pinion 219 rotates in the clockwise direction, and the first protrusion 501 and the second protrusion 504 move upward along the first groove 221 and the second groove 222, respectively.
Further, as the first discharge stacker 500 moves, the discharge frame portion 800 moves downstream in the transport direction.

As shown in FIG. 18, when the pinion 219 further rotates clockwise from the state shown in FIG. 17, the pinion 219 attempts to move the first discharge stacker 500 further upward via the rack 227. Accordingly, the first discharge stacker 500 moves so that the upstream end in the transport direction further rises with the downstream side in the transport direction as a fulcrum. That is, the inclination of the CD-R tray guide surface 523 of the first discharge stacker 500 with respect to the transport direction (Y) is decreased. At this time, the second projecting portion 504 and the second groove portion 222 are biased by the torsion coil spring described above in order to prevent the rack 227 from being separated from the pinion 219 by the biasing force of the torsion coil spring described above. Is provided so that the second protrusion 504 is always located on the opposite side of the rack 227 with respect to the pinion 219 while acting on the first discharge stacker 500.
Further, as the first discharge stacker 500 moves, the discharge frame portion 800 moves downstream in the transport direction.

As shown in FIG. 19, when the pinion 219 further rotates clockwise from the state shown in FIG. 18, the first discharge stacker 500 moves so that the upstream end in the transport direction further rises with the downstream side in the transport direction as a fulcrum. . At this time, the attitude regulating portion 228 of the base body portion 220 comes into contact with the contact protrusion 521 provided on the contact surface 520 of the first discharge stacker 500. The contact protrusion 521 always moves the first discharge stacker 500 to make the posture of the CD-R tray guide surface 523 of the first discharge stacker 500 parallel to the transport direction (Y). 228 and the first discharge stacker 500 are provided so as to be in contact with each other.
Further, as the first discharge stacker 500 moves, the discharge frame portion 800 moves downstream in the transport direction.

As shown in FIG. 20, when the pinion 219 further rotates clockwise from the state shown in FIG. 19, the first discharge stacker 500 moves so that the upstream end in the transport direction further rises with the downstream side in the transport direction as a fulcrum. . At this time, the second discharge driven rollers 503 and 503 provided on the upstream side in the transport direction of the first discharge stacker 500 move to a position near the downstream side in the transport direction of the discharge drive roller 20a on the base unit side.
Further, as the first discharge stacker 500 moves, the discharge frame portion 800 moves downstream in the transport direction.

As shown in FIG. 21, when the pinion 219 further rotates clockwise from the state shown in FIG. 20, the first discharge stacker 500 moves so that the upstream end in the transport direction further rises with the downstream side in the transport direction as a fulcrum. . At this time, the second discharge driven rollers 503 and 503 provided on the upstream side in the transport direction of the first discharge stacker 500 are higher than the discharge drive roller 20a on the base portion side, and the second discharge driven roller The lower part of 503 and 503 moves to a position where it is substantially the same height as the upper part of the discharge drive roller 20a. At this time, the inclination, that is, the posture of the first discharge stacker 500 is such that the CD-R tray guide surface 523 of the first discharge stacker 500 is parallel to the transport direction (Y).
Here, “parallel” means that the CD-R tray Q can be guided to the recording unit 110 and the recorded CD-R tray Q can be received in the main scanning direction X and the conveyance direction (Y). On the other hand, it means being substantially parallel.
As the first discharge stacker 500 moves, the discharge frame portion 800 receives the biasing force of the torsion coil spring and moves upstream in the transport direction.

As shown in FIG. 22, when the pinion 219 further rotates clockwise from the state shown in FIG. 21, the pinion 219 tends to move along the sixth groove 226 downstream in the transport direction. That is, the pinion 219 tries to move the first discharge stacker 500 to the upstream side in the transport direction through the rack 227 in cooperation with the biasing force of the torsion coil spring described above. Therefore, the first discharge stacker 500 is guided by the engagement between the first protrusion 501 and the first groove 221 and is guided by the engagement between the second protrusion 504 and the second groove 222 while being guided in the transport direction. Move upstream. That is, the posture of the first discharge stacker 500 is regulated by the engagement between the first protrusion 501 and the first groove 221 and the engagement between the second protrusion 504 and the second groove 222. Accordingly, the CD-R tray guide surface 523 is translated in the upstream direction in the transport direction while maintaining a posture that is parallel to the transport direction (Y).
As the first discharge stacker 500 moves, the discharge frame portion 800 receives the biasing force of the torsion coil spring and moves upstream in the transport direction.

Here, since the posture of the first discharge stacker 500 has already obtained the desired posture, the contact protrusion 521 of the first discharge stacker 500 is separated from the posture regulating portion 228 of the base body 220. In other words, when the first discharge stacker 500 moves in parallel, the posture regulating unit 228 is provided so as not to act on the first discharge stacker 500 at all. Accordingly, there is no possibility that the posture of the first discharge stacker 500 becomes unstable due to the frictional resistance generated between the posture restricting unit 228 and the first discharge stacker 500.
In addition, due to the urging force of the torsion coil spring described above, a force that rotates the first discharge stacker 500 counterclockwise acts on a position where the first discharge stacker 500 meshes with the pinion 219 in the rack 227. Since the first protrusion 501 of the first discharge stacker 500 is pressed against the lower portion of the first groove portion 221 of the base body 220, the first discharge stacker 500 can hold the posture with high accuracy.
The first discharge stacker 500 is stopped when the pinion 219 is stopped at a position where the lower portions of the second discharge driven rollers 503 and 503 of the first discharge stacker 500 are in contact with the upper portion of the discharge drive roller 20a on the base portion side. Stops. The stop position of the first discharge stacker 500 shown in FIG. 22 is the second position that the first discharge stacker 500 takes in the CD-R recording mode. At this time, the second discharge driven rollers 503 and 503 are biased so as to swing toward the discharge drive roller by a biasing force of a spring (not shown). Accordingly, in the CD-R recording mode, the second discharge driven rollers 503 and 503 cooperate with the discharge drive roller 20a to sandwich the CD-R tray Q, and to the upstream and downstream in the transport direction. Can be moved.

  The timing at which the pinion 219 stops is the direction in which the first driving stacker 500 is separated from the home position detector 230 as described above and the first motor is rotated by a predetermined number of steps and the discharging drive roller 20a is reversely rotated. It is provided to stop after being driven to. Therefore, the second position of the first discharge stacker 500 can be determined with high accuracy.

  As described above, the discharge stacker lifting / lowering device 200 moves so as to first draw the downstream side of the first discharge stacker 500 to the upper side and the downstream side of the discharge stacker lifting / lowering device 200 without coming into contact with the second discharge stacker 600. Next, the upstream side of the first discharge stacker 500 can be moved to be pulled up above the discharge stacker lifting device 200. That is, when the discharge stacker lifting / lowering device 200 moves from the first position to the second position, the discharge stacker lifting / lowering device 200 is located above the first placement portion 510 of the first discharge stacker 500 and the second placement portion 610 of the second discharge stacker 600. Even if the space is restricted by, for example, the bar guide 431, the first discharge stacker 500 can be moved.

[Movement of first discharge stacker from second position to first position]
When the CD-R recording mode is switched to the paper recording mode, the power transmission shown in FIG. 9 is connected from the state where the power transmission is cut by the power transmission switching device 400 shown in FIG. 7 as described above. At this time, the discharge drive roller 20a is driven forward, that is, the sun gear 426 rotates clockwise. Then, the power of the sun gear 426 is transmitted to the pinion 219 by the power transmission means 210. Accordingly, the pinion 219 rotates counterclockwise.

When the pinion 219 rotates counterclockwise from the state shown in FIG. 22, the pinion 219 tends to move along the sixth groove 226 upstream in the transport direction. In other words, the pinion 219 attempts to move the first discharge stacker 500 to the downstream side in the transport direction through the rack 227 against the biasing force of the torsion coil spring described above. Therefore, the first discharge stacker 500 is guided by the engagement between the first protrusion 501 and the first groove 221 and is guided by the engagement between the second protrusion 504 and the second groove 222 while being guided in the transport direction. Move downstream. At this time, the first discharge stacker 500 moves parallel to the downstream side in the transport direction while maintaining the posture in which the CD-R tray guide surface 523 is parallel to the transport direction (Y).
Further, as the first discharge stacker 500 moves, the discharge frame portion 800 moves downstream in the transport direction.

  As shown in FIG. 21, when the pinion 219 rotates counterclockwise from the state shown in FIG. 22, the first discharge stacker 500 moves downstream in the transport direction against the biasing force of the torsion coil spring. . At this time, the second discharge driven rollers 503 and 503 of the first discharge stacker 500 are separated from the discharge driving roller 20a on the base portion side. Further, the abutting protrusion 521 of the first discharge stacker 500 abuts on the attitude regulating portion 228 of the base portion 220 that has been separated. Then, the first protrusion 501 of the first discharge stacker 500 is separated from the lower surface of the first groove 221 by the shape of the first groove 221. Therefore, due to the urging force of the torsion coil spring described above, a force that causes the first discharge stacker 500 to rotate counterclockwise acts at a position where the first discharge stacker 500 meshes with the pinion 219 in the rack 227. At this time, the posture of the first discharge stacker 500 is regulated by the posture regulating unit 228 coming into contact with the contact projection 521.

As shown in FIG. 20, when the pinion 219 is further rotated counterclockwise from the state shown in FIG. . At this time, the second discharge driven rollers 503 and 503 provided on the upstream side in the transport direction of the first discharge stacker 500 move to a position near the downstream side in the transport direction of the discharge drive roller 20a on the base unit side.
As the first discharge stacker 500 moves, the discharge frame unit 800 moves upstream in the transport direction.

As shown in FIG. 19, when the pinion 219 further rotates counterclockwise from the state shown in FIG. 20, the first discharge stacker 500 moves so that the upstream end in the transport direction is further lowered with the downstream side in the transport direction as a fulcrum. To do. At this time, the positions of the second discharge driven rollers 503 and 503 of the first discharge stacker 500 are lower than the position of the discharge drive roller 20a on the base portion side.
As the first discharge stacker 500 moves, the discharge frame unit 800 moves upstream in the transport direction.

As shown in FIG. 18, when the pinion 219 further rotates counterclockwise from the state shown in FIG. 19, the first discharge stacker 500 moves so that the upstream end in the transport direction further descends with the downstream side in the transport direction as a fulcrum. To do. At this time, the posture regulating unit 228 of the base body 220 regulates the posture of the first discharge stacker 500 by being separated from the contact protrusion 521 of the first discharge stacker 500 and contacting the contact surface 520.
As the first discharge stacker 500 moves, the discharge frame unit 800 moves upstream in the transport direction.

  As shown in FIG. 17, when the pinion 219 further rotates counterclockwise from the state shown in FIG. 18, the first discharge stacker 500 moves so that the upstream end in the transport direction further descends with the downstream side in the transport direction as a fulcrum. To do. As the first discharge stacker 500 moves, the discharge frame unit 800 moves upstream in the transport direction.

As shown in FIG. 16, when the pinion 219 further rotates counterclockwise from the state shown in FIG. 17, the first discharge stacker 500 moves so that the upstream end in the transport direction further descends with the downstream side in the transport direction as a fulcrum. To do. At this time, the first protrusion 501 on the upstream side in the transport direction of the first discharge stacker 500 contacts the lower surface of the first groove 221 of the base body 220. As the pinion 219 rotates, the first discharge stacker 500 resists the force that the first discharge stacker 500 rotates counterclockwise due to the biasing force of the torsion coil spring described above. With the portion where 501 and the first groove 221 are in contact with each other as a fulcrum, it moves clockwise so that the downstream side in the transport direction of the first discharge stacker 500 is lowered. Accordingly, the contact surface 520 of the first discharge stacker 500 is separated from the attitude regulating portion 228 of the base body portion 220. At this time, the posture of the first discharge stacker 500 is such that the first protrusion 501 is brought into contact with the lower surface of the first groove 221 of the base body 220 by the force that the first discharge stacker 500 tries to rotate counterclockwise. It is regulated by hitting.
As the first discharge stacker 500 moves, the discharge frame unit 800 moves upstream in the transport direction.

As shown in FIG. 15, when the pinion 219 further rotates counterclockwise from the state shown in FIG. 16, the pinion 219 attempts to move along the sixth groove 226 downstream in the transport direction. That is, the pinion 219 tries to move the first discharge stacker 500 to the upstream side in the transport direction through the rack 227 in cooperation with the biasing force of the torsion coil spring described above. Therefore, the first discharge stacker 500 is guided by the engagement between the first protrusion 501 and the first groove 221 and is guided by the engagement between the second protrusion 504 and the second groove 222 while being guided in the transport direction. Move upstream. At this time, the posture of the first discharge stacker 500 is regulated by the engagement between the first protrusion 501 and the first groove 221 and the engagement between the second protrusion 504 and the second groove 222. That is, the first discharge stacker 500 moves parallel to the upstream side while maintaining the posture in which the upstream side in the transport direction is lowered and the downstream side is raised.
Further, along the movement of the first discharge stacker 500, it is guided by the engagement between the fourth protrusion 801 and the fourth groove 224 and the engagement between the fifth protrusion 802 and the fifth groove 225, and upstream in the conveying direction. And move downward.

As shown in FIG. 14, when the pinion 219 further rotates counterclockwise from the state shown in FIG. 15, the first discharge stacker 500 engages with the first protrusion 501 and the first groove 221 and the second protrusion. While being guided by the engagement between the portion 504 and the second groove 222, the upstream side in the transport direction is lowered and the downstream side is raised, and the translation is performed in the upstream direction. Further, the discharge frame portion 800 moves with the movement of the first discharge stacker 500, and the lower portions of the first discharge driven rollers 20b, 20b,. It contacts the upper part of 20a. At this time, the fourth projecting portion 801 and the fifth projecting portion 802 of the discharge frame portion 800 hit the upstream ends of the fourth groove portion 224 and the fifth groove portion 225 of the base body portion 220 in the conveying direction, respectively, and the discharge frame portion 800 stops. To do.
Further, the fourth projecting portion 801 and the fifth projecting portion 802 hit the upstream ends in the conveying direction of the fourth groove portion 224 and the fifth groove portion 225 of the base body portion 220, respectively. It does not reach the first discharge stacker 500.

As shown in FIG. 13, when the pinion 219 further rotates counterclockwise from the state shown in FIG. 14, the first discharge stacker 500 moves parallel to the upstream side in the transport direction. At this time, the discharge frame portion 800 is held in a stopped state by the biasing force of the torsion coil spring described above. Accordingly, the third protrusion 701 of the connecting arm 700 moves away from the upstream end in the transport direction of the third groove 223 of the first discharge stacker 500 and moves downstream.
Here, the first discharge stacker 500 is provided to move in parallel to the upstream side in the transport direction until the downstream end in the transport direction of the first discharge stacker 500 is located upstream from the upstream end of the second discharge stacker 600. It has been.

  As shown in FIG. 12, when the pinion 219 further rotates counterclockwise from the state shown in FIG. 13, the pinion 219 attempts to move upward along the sixth groove portion 226. That is, the pinion 219 tries to move the first discharge stacker 500 downward through the rack 227. Accordingly, the first discharge stacker 500 rotates clockwise with the first protrusion 501 as a fulcrum so that the downstream end in the transport direction is lowered and the height difference between the upstream end and the downstream end is reduced.

As shown in FIG. 11, when the pinion 219 further rotates counterclockwise from the state shown in FIG. 12, the first discharge stacker 500 descends at the downstream end in the transport direction with the first protrusion 501 as a fulcrum. And turn clockwise so that the difference in height between the downstream end and the downstream end is further reduced.
As shown in FIG. 10, when the pinion 219 further rotates counterclockwise from the state shown in FIG. 11, the first discharge stacker 500 descends with the first protrusion 501 as a fulcrum and the downstream end in the transport direction descends to the upstream end. And turn clockwise so that the difference in height between the downstream end and the downstream end is further reduced. At this time, the first discharge stacker 500 contacts the home position detector 230. Then, the home position detector 230 detects the first discharge stacker 500, stops the driving of the first motor, and stops the rotation of the pinion 219. Accordingly, the first discharge stacker 500 is accurately positioned at the first position.

  As described above, the discharge stacker lifting / lowering device 200 moves so as to push the upstream side of the first discharge stacker 500 into the lower side and upstream of the discharge stacker lifting / lowering device 200 without coming into contact with the second discharge stacker 600. Then, the downstream side of the first discharge stacker 500 can be moved so as to be pushed below the discharge stacker lifting device 200. That is, when the discharge stacker lifting / lowering device 200 moves from the second position to the first position, the first stacker 510 of the first discharge stacker 500 and the second stacker 610 of the second discharge stacker 600 are located above. Even if the space is restricted by, for example, the bar guide 431, the first discharge stacker 500 can be moved.

  Further, when the first discharge stacker 500 moves from the second position to the first position, the discharge drive roller 20a is driven to rotate forward. The forward rotation means a clockwise rotation in FIGS. Accordingly, even when the CD-R tray Q is sandwiched between the discharge drive roller 20a and the second discharge driven rollers 503 and 503, that is, when the CD-R tray Q is not normally discharged after recording, the discharge drive roller 20a. The second discharge driven rollers 503 and 503 can cooperate to move the CD-R tray Q to the downstream side in the transport direction. Then, the CD-R tray Q is not nipped by the discharge drive roller 20a and the second discharge driven rollers 503 and 503. As a result, the CD-R tray Q is moved to the first position while the CD-R tray Q is nipped between the discharge driving roller 20a and the second discharge driven rollers 503 and 503, whereby the CD-R tray Q is moved to the first position. There is no risk of the tray Q being damaged. Further, when the first discharge stacker 500 moves from the second position to the first position, the discharge drive roller 20a and the second discharge driven rollers 503 and 503 do not have the possibility of involving the CD-R tray Q. This is effective when the user leaves the CD-R tray Q in the CD-R tray guide opening of the first discharge stacker 500.

  Further, since only the first discharge stacker 500 is moved instead of the entire discharge stacker 50, the weight of the moved member is lighter than when the entire discharge stacker 50 is moved. Therefore, the power source can be reduced in size accordingly.

[Opening and closing the second discharge stacker]
23 to 25 are side views showing opening and closing of the second discharge stacker according to the present invention. 23 shows a state in which the second discharge stacker is closed, FIG. 24 shows a state in the middle of opening, and FIG. 25 shows an open state.

  As shown in FIG. 23, when the power is turned off, the first discharge stacker 500 is provided so as to be located at the first position, and the second discharge stacker 600 is in a state where the placement opening 260 is closed. The second discharge stacker 600 is configured to be kept closed by a lock lever (not shown) with a spring force. When the power source is switched on and the CD-R recording mode is selected, the first discharge stacker 500 moves from the first position to the second position as described above.

  As shown in FIG. 24, when the first discharge stacker 500 moves from the first position to the second position, the first discharge stacker 500 moves upward and then moves downstream in the transport direction. At this time, the downstream end in the transport direction of the first discharge stacker 500 abuts and presses against the second placement portion 610 on the front end side from the cover shaft 601 of the second discharge stacker 600. Accordingly, the second discharge stacker 600 rotates in the clockwise direction in the drawing with the cover shaft 601 as a fulcrum.

As shown in FIG. 25, when the second discharge stacker 600 is pushed by the first discharge stacker 500 and pivots clockwise to some extent, the second discharge stacker 600 is slowly rotated by its own weight and a damper (not shown) that resists its own weight. Keep doing. Then, the second discharge stacker 600 comes into contact with the cover restricting portion 250 of the base portion 220 and stops. That is, when the CD-R recording mode is selected, the second discharge stacker 600 is automatically opened even when it is closed.
As described above, when the CD-R recording mode is selected, the user sets the CD-R tray Q to the CD-R tray guide opening 522 of the first discharge stacker 500 to close the second discharge. There is no need to manually open the stacker 600.
Of course, the user can manually open and close the second discharge stacker.

[CD-R recording mode]
FIG. 26 is a schematic side view showing a second position of the first discharge stacker according to the present invention. FIG. 26 is also a schematic side view of the state shown in FIG.
As shown in FIG. 26, when the first discharge stacker 500 is in the second position, the CD-R tray Q is inserted from the CD-R tray guide opening 522 along the CD-R tray guide surface 523. When set in the set position shown in FIG. 6, the upstream end in the transport direction of the CD-R tray Q is sandwiched between the discharge driving roller 20a and the second discharge driven rollers 503 and 503 as shown in FIG. It becomes a state.

  Thereafter, the paper is sent upstream in the transport direction by the reverse drive of the discharge driving roller 20a. Then, the downstream end in the transport direction of the CD-R attached to the CD-R tray Q stops at a position facing the recording head 13, that is, a so-called recording start position. Thereafter, the ejection drive roller 20a is driven to rotate in the forward direction, and the recording head 13 is scanned in the main scanning direction X while the CD-R tray Q is moved downstream in the transport direction, and recording is performed on the CD-R label. To do. When the recording is completed, the discharge driving roller 20a and the second discharge driven rollers 503 and 503 cooperate to discharge the CD-R tray Q to the downstream side in the transport direction. At this time, the upstream end in the transport direction of the CD-R tray Q is disengaged from the nip between the discharge driving roller 20a and the second discharge driven rollers 503 and 503, so that the CD-R tray Q is CD- The CD-R tray Q stops at a position protruding further than the position where a part of the CD-R tray Q protrudes from the R tray guide opening 522.

  Of course, instead of the CD-R tray, the sheet may be manually set in the CD-R tray guide opening of the first discharge stacker.

[Other embodiment 1]
FIG. 27 is a perspective view showing the first discharge stacker in the first position according to the other embodiment 1. FIG. 28 is a side view of FIG.
As shown in FIG. 27 and FIG. 28, the first mounting portion 510 of the first discharge stacker 500 is provided with a guide surface portion 540 that can move upward. The guide surface portion 540 is a member above the CD-R tray guide opening 522, forms the upper surface of the CD-R tray guide opening 522, and guides the CD-R tray Q in the CD-R recording mode. The paper P recorded in the paper recording mode is placed. Since other members are the same as those in the above-described embodiment, the same reference numerals are used, and the description thereof is omitted.

Here, the guide surface portion 540 may be the entire first placement portion 510 in the main scanning direction X, or may be only in a range where the CD-R tray guide opening 522 is provided. Further, in the transport direction (Y), it may be the entire first placement unit 510 or only a part on the downstream side in the transport direction.
Further, the guide surface portion 540 may be configured to swing upward with the upstream side in the transport direction as a fulcrum and the downstream side being the second position side.

  In the CD-R recording mode, when recording on the label surface of the CD-R is performed and then switched to the paper recording mode, the first discharge stacker 500 moves from the second position to the first position. At this time, there is a possibility that the first discharge stacker 500 may move from the second position to the first position while the user leaves the CD-R tray Q in the CD-R tray guide opening. So-called forgetting to take out the CD-R tray Q. In such a case, the CD-R tray Q moves to the first position together with the first discharge stacker 500. At this time, since the CD-R tray Q protrudes from the CD-R tray guide opening 522, the CD-R tray Q comes into contact with the second placement portion 610 of the second discharge stacker 600. That is, the second stacking unit 610 acts to regulate the first discharge stacker 500 and the CD-R tray Q that are about to move downward.

  At this time, the guide surface portion 540 of the first discharge stacker 500 is provided to be movable upward with respect to the first discharge stacker 500. Therefore, the CD-R tray Q and the guide surface portion 540 are restricted by the second placement portion 610 and can be stopped with respect to the base portion of the first discharge stacker 500 that continues to move to the first position that is below. . At this time, a force is applied to the CD-R tray Q by the weight of the guide surface portion 540. In other words, the CD-R tray Q is in a state of being lightly sandwiched between the second mounting portion 610 and the guide surface portion 540, and the CD-R tray Q is so damaged that the CD-R tray Q is damaged. There is no risk of strong forces acting.

As described above, even if the user leaves the CD-R tray Q unattended, there is no possibility that the CD-R tray Q is damaged due to the movement of the first discharge stacker 500. The user can take out the CD-R tray Q from the CD-R tray guide opening 522 when noticing that the user forgets to remove it.
Even when the CD-R tray Q is left unattended, the guide surface portion 540 only moves slightly upward, so that the first placement portion 510 including the guide surface portion 540 in the paper recording mode. The paper P recorded on the second placement unit 610 can be placed.

  In addition, instead of the guide surface portion 540 of the first discharge stacker 500 moving upward, the upstream side in the transport direction of the second mounting portion 610 of the second discharge stacker 600 resists the urging force of a spring or the like. Of course, it may be provided so as to slightly swing downward with the side as a fulcrum. Further, not only the upstream side of the second mounting part 610 but also the whole part of the second mounting part 610 may move downward relative to the second discharge stacker 600 against the urging force of a spring or the like. Of course, it may be provided as possible.

  The discharge stacker lifting / lowering device 200 according to the other embodiment 1 ejects ink from the recording head 13 provided in the recording unit 110 that is an example of the liquid ejecting unit, and is a sheet P that is a non-rigid medium as a first medium.

Since all members are the same as those in the above-described embodiment, the same reference numerals are used and the description thereof is omitted.

  In the CD-R recording mode, when recording on the label surface of the CD-R is performed and then switched to the paper recording mode, the first discharge stacker 500 moves from the second position to the first position. At this time, there is a possibility that the first discharge stacker 500 may move from the second position to the first position while the user leaves the CD-R tray Q in the CD-R tray guide opening. So-called forgetting to take out the CD-R tray Q. In such a case, the CD-R tray Q moves to the first position together with the first discharge stacker 500.

  Then, the CD-R tray Q approaches the second placement portion 610 of the second discharge stacker 600 and abuts lightly. Thereafter, the first discharge stacker 500 moves slightly downward and stops at the first position. At this time, a part of the upper side which is the second position side of the CD-R tray guide opening 522 is provided so as to be higher than the position of the upstream end of the second mounting portion 610. Further, the length of the CD-R tray guide opening 522 in the thickness direction is larger than the thickness of the CD-R tray Q.

At this time, the CD-R tray Q is not in contact with the upper surface of the CD-R tray guide opening 522. That is, the CD-R tray Q is in a state where the upstream end is supported by the CD-R tray guide surface 523 of the first discharge stacker 500 and the downstream side is supported by the second placement unit 610 of the second discharge stacker 600. . Furthermore, in other words, the CD-R tray Q is in a state where a force that is strong enough to damage the CD-R tray Q is not applied.

As described above, even if the user leaves the CD-R tray Q unattended, there is no possibility that the CD-R tray Q is damaged due to the movement of the first discharge stacker 500. The user can take out the CD-R tray Q from the CD-R tray guide opening 522 when noticing that the user forgets to remove it.
Even if the CD-R tray Q is left unattended, the positions of the first placement unit 510 and the second placement unit 610 do not change, and therefore the first placement unit 510 in the paper recording mode. The paper P recorded on the second placement unit 610 can be placed.
Note that the first position of the first discharge stacker 500 may be configured such that the CD-R tray Q left in the CD-R tray guide opening does not come into contact with the second placement unit 610. Of course it is good.

  The discharge stacker lifting / lowering apparatus 200 according to another embodiment 2 ejects ink from the recording head 13 provided in the recording unit 110 which is an example of the liquid ejecting unit, and the paper P which is a non-rigid medium as a first medium and A first position for stacking sheets P recorded on the recording apparatus 100 for recording on a CD-R tray Q to which a CD-R, which is a rigid medium as a second medium, is mounted, and the sheet P and the CD-R tray A discharge stacker lifting / lowering device 200 including a first discharge stacker 500 that guides Q to the recording unit 110 and moves to a second position for receiving the recorded paper P and the CD-R tray Q.

At this time, the positions of the discharge driving roller 20a and the first discharge driven roller 20b are constant, and the relatively small size paper P1 is released from the nip between the discharge drive roller 20a and the first discharge driven roller 20b. Then, it is mounted on the first mounting portion 510 of the lower first discharge stacker 500 by its own weight. That is, the relatively small size paper P1 is not discharged to the second placement unit 610 of the second discharge stacker 600 on the downstream side in the transport direction. Therefore, when the first discharge stacker 500 is at a deep position on the upstream side in the transport direction of the placement opening 260, it may be difficult for the user to take out the recorded small size paper P1. In such a case, when taking out the small-sized paper P1, the user cannot accurately visually recognize the position of the paper P1, and the user may accidentally touch the recording surface of the paper P1.

  Therefore, as shown in FIG. 32, the guide surface portion 550 of the first discharge stacker 500 is provided so as to slide relative to the first discharge stacker 500 and move downstream in the transport direction. Therefore, the user can pull out the guide surface portion 550 toward the transport downstream side, which is the front side, and can pinch and take out the end portion of the small size paper P1. At this time, the user can pull out the guide surface portion 550 to a position where the sheet P1 can be visually recognized. Further, when pulling out the guide surface portion 550, a wall portion 550a perpendicular to the guide surface portion 550 is provided on the upstream side of the guide surface portion 550 in the transport direction. Accordingly, even when the user pulls out the guide surface portion 550 vigorously, the wall portion 550a contacts the upstream end of the paper P1, so that the paper P1 can be reliably moved downstream.

Of course, the guide surface portion 550 may be provided so as to be removable from the first discharge stacker 500.
Of course, the guide surface portion 550 may be configured to automatically move to the downstream side in the transport direction with respect to the first discharge stacker 500.
Furthermore, the present invention is not limited to the above-described embodiments, and various modifications are possible within the scope of the invention described in the claims, and these are also included in the scope of the present invention. Needless to say.
