Description

  The present invention provides a first position for placing a first medium recorded in a recording apparatus that ejects ink from a recording head provided in a recording unit to record on a first medium and a second medium; and A power generating unit provided in the recording apparatus moves the first medium and the second medium to the recording unit and receives the recorded first medium and the second medium to a second position. The present invention relates to a discharge stacker lifting apparatus including a moving discharge stacker, a recording apparatus including the discharge stacker lifting apparatus, and a liquid ejecting apparatus including the discharge stacker lifting apparatus.

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.
The recording apparatus includes types such as an ink jet printer, a wire dot printer, a laser printer, a line printer, a copying machine, and a facsimile.

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.

In the related art, 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). -Patent Document 4). 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.

  On the other hand, when recording the CD-R label surface, the CD-R is attached to a dedicated CD-R tray and recorded in order to convey the disc-shaped CD-R with good posture. 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, a new linear conveyance path is provided, and the CD-R tray is moved to a position where the recording head can record on the label surface of the CD-R. 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, since the thickness of the paper and the thickness of the CD-R tray are different, the distance between the recording head and the CD-R tray, the so-called platen gap (also referred to as a paper gap, hereinafter referred to as PG) is changed and adjusted. There is a need to. Further, it is necessary to change the discharge roller pair. Normally, the discharge driven roller, which is the driven side of the discharge roller pair, sandwiches the paper in cooperation with the driving roller, and has a protruding shape to minimize the contact area with the recording surface of the paper. The so-called giza roller is used.

However, if the jagged roller is used for moving the CD-R tray, there is a possibility that the data information recorded on the CD-R may be damaged by contacting the label surface of the CD-R.
Therefore, conventionally, when recording on the label surface of the CD-R, the jagged roller is retracted from the driving side roller, that is, so-called release.
Japanese Patent No. 3633509 JP 2004-090448 A JP 2004-34637 A JP 2003- 211760 A

Further, in the configuration in which the discharge stacker is movably provided and serves as both the discharge stacker and the CD-R tray guide, the discharge stacker and the like are only manually moved individually. Therefore, when the user's operation is uncertain, there is a possibility that the operations of the discharge stacker, the jagged roller and the like become unstable. For example, although the discharge stacker is located at a position taken when recording a rigid medium, there is a possibility that a state where a misoperation is not consistent due to an operation not being located at a position where the jagged roller is taken when recording a rigid medium may occur.

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. At this time, on the upstream side of the CD-R tray Q, the conveyance roller 19a is in contact with the label surface of the CD-R to prevent the data stored in the CD-R from being damaged. 19 so as not to be sandwiched between the two.

  The ejection drive roller 20a and the second ejection driven rollers 503 and 503 do not directly sandwich the CD-R, but 2 so as to sandwich the vicinity of both sides in the main scanning direction of the CD-R tray main body (Q). One is provided. Therefore, there is no possibility of damaging the data information stored on the CD-R. Further, in order to improve the conveyance accuracy of the CD-R tray, not only the ejection drive roller 20a and the second ejection driven rollers 503 and 503 but also the conveyance roller 19 carries the CD-R tray while sandwiching it. Of course, you may comprise.

  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]
FIG. 7 to FIG. 9 are schematic side views showing power transmission to the discharge stacker lifting device according to the present invention. Of these, FIG. 7 shows a state in which the power is cut off. FIG. 8 shows a state in which power is transmitted in the reverse rotation state of the discharge drive roller, and FIG. 9 shows a state in which power is transmitted in the forward rotation state of the discharge drive roller.

  As shown in FIG. 7, the recording apparatus 100 includes a recording unit gap adjusting device 300 that can adjust the distance between the recording head 13 provided in the recording unit 110 and the platen 28 according to the thickness of the paper and the like. In order to guide and receive the CD-R tray Q when recording a label, the power of the discharge stacker elevating device 200 that moves the first discharge stacker 500 and the power of the discharge drive roller 20a is transmitted to the discharge stacker elevating device 200. A power transmission switching device 400 that switches between the two is provided.

Among these, the recording unit gap adjusting device 300 includes a cam shaft 302 that is rotated by a PG adjusting motor that is a second motor (not shown), and a carriage guide that is provided so as to be eccentric with respect to the rotation fulcrum of the cam shaft 302.

  The recording head 13 is provided on the carriage 10 that moves in the main scanning direction X by the carriage guide shaft 12. 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.

  The side of the lever member 304 opposite to the side on which the lever contact portion 303 is provided is rotatably connected to one end of a slide bar 430 that reciprocates in the horizontal direction by a bar guide 431 provided on the base portion 220. ing.

The planetary gear holder 420 holding the first planetary gear 423 and the second planetary gear 424 by the rotation of the sun gear 426 tries to rotate in the same direction as the rotation direction of the sun gear 426, but the lock lever The posture is regulated by 410. 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.

Since the seventh gear 217 is provided integrally with the sixth gear 216, the seventh gear 217 rotates counterclockwise integrally with the sixth gear 216. The power of the seventh gear 217 is transmitted to the eighth gear 218, and the eighth gear 218 rotates clockwise. Since the pinion 219 is provided integrally with the eighth gear 218, the pinion 219 rotates clockwise together with the eighth gear 218.

  When the pinion 219 rotates in the clockwise direction, the pinion 219 is provided to move the first discharge stacker 500 from the first position to the second position via the rack 227 provided on the first discharge stacker side.

On the other hand, when switching from the CD-R recording mode to the paper recording mode, the cam shaft 302 rotates clockwise from the state shown in FIG. 7, and the lever member 304 rotates clockwise to the position shown in FIG. 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.

  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.

That circumscribe the discharge drive roller 20a on the base portion side while being urged by a spring (not shown). I have. Further, the discharge frame portion 800 is always urged upstream in the conveying direction by an urging force F of a torsion coil spring (not shown) as the urging means 805 provided in the base portion 220. That is, the torsion coil spring (not shown) moves toward the position of the discharge frame portion 800 when the first discharge driven rollers 20b, 20b, ... circumscribe and cooperate with the discharge drive roller 20a. Is energized.
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 901 when the first discharge stacker 500 moves from the first position to the second position is a predetermined step after the first discharge stacker 500 is separated from the home position detector 230. Controlled to stop at number. On the other hand, the driving amount of the first motor 901 when the first discharge stacker 500 moves from the second position to the first position is such that the first discharge stacker 500 comes into contact with the home position detector 230 and stops. It is controlled.
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, and thus the number of steps of the first motor 901 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. Accordingly, the first discharge stacker 500 is guided 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, and the pinion 219 and the rack 227. It moves to the conveyance direction downstream side, being guided by. At this time, the inclination, that is, the posture of the first discharge stacker 500 is determined by the engagement between the first protrusion 501 and the first groove 221, the second protrusion 504 and the second groove 222, and the pinion 219 and the rack 227. Since it is regulated by the engagement, 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 the engagement between the second protrusion 504 and the second groove 222, and the pinion 219 and the rack 227. The guide further moves downstream in the transport 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 conveying direction against the biasing force F 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.
The discharge auxiliary driven rollers 22, 22,... (See FIG. 3) move in the same direction as the first discharge driven rollers 20b, 20b,. Has been.

  Further, due to the biasing force F 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 to the downstream side 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 F 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 F 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 meshed 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 in which the contact surface 520 is in contact with the posture restricting portion 228, the place where the third protrusion 701 and the third groove 223 contact where the biasing force F of the torsion coil spring acts is the rack 227. Is located between the portion meshing with the pinion 219 and the portion of the contact surface 520 that is in contact with the attitude regulating portion 228. Therefore, the posture restricting portion 228 abuts on the counterclockwise rotation of the first discharge stacker 500 around the position where the first discharge stacker 500 is engaged with the pinion 219 in the rack 227 by the biasing force F of the torsion coil spring. It can be regulated by contacting the surface 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 protrusion 504 and the second groove 222 are attached to the torsion coil spring described above in order to prevent the rack 227 from being separated from the pinion 219 by the biasing force F of the torsion coil spring described above. While the force F acts on the first discharge stacker 500, the second protrusion 504 is always located on the opposite side of the rack 227 with respect to the pinion 219.
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 urging force F 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 F 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 urging force F 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.

  Further, by the biasing force F of the torsion coil spring described above, a force that rotates the first discharge stacker 500 counterclockwise acts at a position where the first discharge stacker 500 meshes with the pinion 219 in the rack 227. However, since the first protrusion 501 of the first discharge stacker 500 is pressed against the lower portion of the first groove 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 pinion 219 is stopped when the first discharge stacker 500 is separated from the home position detector 230 as described above, and the first motor 901 and the discharge drive roller 20a are reversed by a predetermined number of steps. It is provided to stop after being driven in the direction. 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. Then, the upstream side of the first discharge stacker 500 can be moved so as 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 against the biasing force F of the torsion coil spring through 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 the engagement between the second protrusion 504 and the second groove 222, and the pinion 219 and the rack 227. It moves to the conveyance direction downstream side, being guided by. 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 conveying direction against the biasing force F of the torsion coil spring. To do. 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, a force for rotating the first discharge stacker 500 counterclockwise acts at a position where the first discharge stacker 500 is engaged with the pinion 219 in the rack 227 by the biasing force F of the torsion coil spring described above. . 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 further rotates counterclockwise from the state shown in FIG. 21, the first discharge stacker 500 moves with the downstream side in the transport direction as a fulcrum so that the upstream end in the transport direction is lowered. . 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 F of the torsion coil spring described above. With the portion where the portion 501 and the first groove 221 are in contact with each other as a fulcrum, the portion 501 rotates clockwise and moves 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 F of the torsion coil spring described above. Accordingly, the first discharge stacker 500 is guided 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, and the pinion 219 and the rack 227. It moves to the conveyance direction upstream side, being guided by. 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, the second protrusion 504 and the second groove 222, and the engagement between the pinion 219 and the rack 227. Has been. 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, as the first discharge stacker 500 moves, the discharge frame portion 800 is engaged 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. It is guided and moves downward in the conveying direction and downward.

As shown in FIG. 14, when the pinion 219 is further rotated counterclockwise from the state shown in FIG. 15, the first discharge stacker 500 is engaged with the first protrusion 501 and the first groove 221 and the second protrusion. While being guided by the engagement of 504 and the second groove 222, and the pinion 219 and the rack 227, the upstream side in the conveying direction is lowered and the downstream side is raised, and the parallel movement is made upstream. 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 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 come into contact with the upstream ends of the fourth groove portion 224 and the fifth groove portion 225 of the base body 220 in the conveying direction, respectively, so that the biasing force F of the torsion coil spring described above is applied. This 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 F 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 901, 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 in the closed state in order to set the CD-R tray Q in the CD-R tray guide opening 522 of the first discharge stacker 500. 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 on the CD-R tray guide surface of the CD-R tray guide opening of the first discharge stacker.

The discharge stacker lifting / lowering device 200 of the present embodiment ejects ink from the recording head 13 provided in the recording unit 110 which is an example of a liquid ejecting unit, and the sheet P and the second medium P which are non-rigid media as a first medium. The recording apparatus 100 for recording on a CD-R tray Q to which a CD-R which is a rigid medium as a medium is mounted, a first position on which the recorded paper P is placed, and the paper P and the CD-R tray Q. Is moved to a second position for receiving the recorded paper P and the CD-R tray Q by a first motor 901 as a power generation unit provided in the recording apparatus 100. A discharge stacker lifting / lowering device 200 including a first discharge stacker 500 serving as a discharge stacker to be provided is provided on the base portion side of the discharge stacker lifting / lowering device 200, and the paper P and C -The discharge driving roller 20a for moving the R tray Q in the transport direction (Y) and the first discharge driven roller 20b for nipping the paper P in cooperation with the discharge driving roller 20a are rotatably held. The discharge frame portion 800 is movable in the direction in which the first discharge driven roller 20b moves toward and away from the discharge drive roller 20a, and the discharge frame portion 800 is divided into the first discharge driven roller 20b and the discharge drive roller 20a. And a torsion coil spring (not shown) as urging means 805 for urging toward the cooperating position side, the discharge frame portion 800 is connected to the first discharge stacker 500, and the first discharge stacker 500 is connected to the first discharge stacker 500. The first discharge driven roller 20 resists the biasing force F of the torsion coil spring (not shown) as the biasing means 805 as it moves from the first position to the second position. There, characterized in that it is configured to move in a direction away from the discharge drive roller 20a.

[Other Embodiments]
Next, another embodiment will be described.
The main difference between the discharge stacker lifting device 1200 according to another embodiment and the discharge stacker lifting device 200 according to the above-described embodiment is that the discharge stacker lifting device 1200 according to another embodiment includes a slider portion 550 described later. It is a point. Furthermore, in the discharge stacker lifting apparatus 200 of the above-described embodiment, there is one urging means that acts on the first discharge stacker.

In other embodiments, the 2nd projection part 504 and the 2nd groove part 222 of an embodiment mentioned above are deleted.
27 to 37 are side views showing the movement of the first discharge stacker of the discharge stacker lifting device according to another embodiment. Of these, FIG. 27 shows the first position of the first discharge stacker, FIGS. 28 to 36 show the movement from the first position to the second position, and FIG. 37 shows the second position.

[Movement of First Discharge Stacker According to Other Embodiment from First Position to Second Position]
As shown in FIG. 27, the first discharge stacker 1500 includes a pair of slider guide groove portions 540 and 540 on both sides in the main scanning direction, and a pair of slider portions 550 that are guided by the slider guide groove portions 540 and 540 and slide in the slider guide groove portions. 550 and a pair of second springs 922 and 922 as second urging means for urging the slider portions 550 and 550 to the upstream side in the transport direction with respect to the first discharge stacker 1500. One end of the second springs 922 and 922 is engaged with slider-side spring engaging portions 551 and 551 provided on the slider portions 550 and 550, and the other end is on the discharge stacker side provided on the first discharge stacker 1500. The spring engagement portion 541 is engaged. Further, the pair of slider portions 550 and 550 are provided with a pair of third groove portions 223 and 223 that engage with the connecting arm portion 700.

Further, the first discharge stacker 1500 includes sixth groove portions 226 and 226 provided in pairs on both sides in the main scanning 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 first discharge stacker 1500 is in contact with a position sensor 230 provided on the base 220 and a first sensor abutting portion 543 that abuts at a first position which is a so-called home position, and a second sensor abutting at a second position. 2 sensor contact portion 544. The position detector 230 is provided so as to be switched to an ON (upper position) -OFF (neutral position) -ON (lower position) state depending on the position of the protrusion 231. Therefore, in the first position, the first sensor contact portion 543 contacts the position detector 230 and pushes the protrusion 231 downward, so that the ON state is established.

  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. A pair of fifth protrusions 802, 802 to be joined and guided, and first discharge driven rollers 20b, 20b,... That circumscribe the discharge drive roller 20a on the base portion side while being urged by a spring (not shown). I have. Further, the discharge frame portion 800 is taken by the discharge frame portion 800 when the first discharge stacker 1500 that is always upstream in the transport direction is at the first position by the first spring 921 as the first urging means. Biased to position. One end of the first spring 921 is engaged with a discharge frame side spring engaging portion 803 provided in the discharge frame portion 800, and the other end is engaged with a base side spring engaging portion 232 provided in the base portion 220. Match.

In the first position, the second springs 922 and 922 bias the slider portions 550 and 550 in the first discharge stacker 1500 toward the upstream side in the transport direction. At this time, the urging force F <b> 2 of the second springs 922 and 922 is such that the third protrusions 701 and 701 of the connecting arm portion 700 are in contact with the downstream side of the third grooves 223 and 223 of the slider portions 550 and 550. , Acting on the connecting arm portion 700. That is, the urging force F <b> 2 of the second springs 922 and 922 acts on the discharge frame part 800 via the connection arm part 700. Accordingly, the discharge frame portion 800 is in contact with the upstream side of the fourth groove portions 224 and 224 and the fourth protrusions 801 and 801, and the upstream side of the fifth groove portions 225 and 225 and the throat of the fifth protrusions 802 and 802. Therefore, positioning can be performed with high accuracy.
On the other hand, the urging force F <b> 1 of the first spring 921 hardly acts on the discharge frame portion 800.

Note that the driving amount of the first motor 901 when the first discharge stacker 1500 moves from the first position to the second position hits when the first position reaches the second position, and the motor load increases. The controller 900 is controlled to stop or stop at a predetermined number of steps after the first sensor contact portion 543 provided in the first discharge stacker 1500 is separated from the position detector 230. On the other hand, the driving amount of the first motor 901 when the first discharge stacker 1500 moves from the second position to the first position hits when the first position reaches the first position, and the motor load increases. The second sensor abutting portion 544 provided in the first discharge stacker 1500 is controlled to stop at a predetermined number of steps after being separated from the position detector 230.
In the following description, a pair of second springs, slider portions, third protrusions, fourth protrusions, fifth protrusions, slider guide groove portions, third groove portions, fourth groove portions provided in the main scanning direction, and Since the fifth groove has the same shape on the left and right and is synchronized, only one side will be described, and the description on the other side will be omitted.

As shown in FIG. 28, when the pinion 219 rotates clockwise from the state shown in FIG. 27, power is transmitted to the rack 227 of the first discharge stacker 1500.
At this time, the slider portion 550 is restricted by the third protrusion 701 of the connecting arm portion 700 and gradually moves in the slider guide groove portion downstream in the transport direction against the urging force F2 of the second spring 922. .

  As shown in FIG. 29, when the pinion 219 further rotates clockwise from the state shown in FIG. 28, the pinion 219 attempts to move the first discharge stacker 1500 further upward via the rack 227. Accordingly, the first discharge stacker 1500 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 1500 in the transport direction is higher than the upper end of the upstream end of the second discharge stacker 600 in the transport direction.

At this time, the slider portion 550 is restricted by the third protrusion 701 of the connecting arm portion 700, and further moves in the slider guide groove portion downstream in the transport direction against the urging force F2 of the second spring 922. Then, the slider portion 550 stops at a position where it does not come into contact with the downstream end of the slider guide groove portion 540. At this time, since the second spring 922 extends to the maximum extent, the urging force F2 of the second spring 922 has a maximum value. That is, the discharge frame portion 800 is in a state where it is most strongly subjected to the action of the second spring 922 via the connecting arm portion 700.
When the downstream end of the first discharge stacker 1500 rises, the first sensor contact portion 543 is separated from the position detector 230 and is turned off, and the count of the number of steps of the first motor 901 is started.

As shown in FIG. 30, when the pinion 219 further rotates clockwise from the state shown in FIG. 29, the pinion 219 tends to move along the sixth groove 226 to the upstream side in the transport direction. That is, the pinion 219 tries to move the first discharge stacker 1500 to the downstream side in the transport direction via the rack 227.
At this time, the slider portion 550 moves in the slider guide groove portion to the upstream side in the transport direction with the urging force F2 of the second spring 922. That is, the urging force F <b> 2 of the second spring 922 assists the movement of the first discharge stacker 1500 downstream in the transport direction. Therefore, the load on the first motor 901 can be reduced.

As shown in FIG. 31, when the pinion 219 further rotates clockwise from the state shown in FIG. 30, the pinion 219 attempts to move the first discharge stacker 1500 further downstream in the transport direction via the rack 227. . Accordingly, the first discharge stacker 1500 is guided by the engagement between the first protrusion 501 and the first groove 221 and further moved downstream in the transport direction while being guided by the engagement between the pinion 219 and the rack 227. To do.
At this time, the slider portion 550 further moves in the slider guide groove portion to the upstream side in the transport direction with the urging force F2 of the second spring 922. And since the 2nd spring 922 contracts gradually, the urging | biasing force F2 of the 2nd spring 922 also reduces gradually. That is, the action of the second spring 922 received by the discharge frame portion 800 via the connecting arm portion 700 gradually decreases.

  As shown in FIG. 32, when the pinion 219 further rotates clockwise from the state shown in FIG. 31, the pinion 219 tries to move the first discharge stacker 1500 further downstream in the transport direction via the rack 227. . Accordingly, the first discharge stacker 1500 is guided by the engagement between the first protrusion 501 and the first groove 221 and further moved downstream in the transport direction while being guided by the engagement between the pinion 219 and the rack 227. To do.

  At this time, the slider portion 550 further moves in the slider guide groove portion to the upstream side in the transport direction with the urging force F2 of the second spring 922, and comes into contact with the upstream end 540a of the slider guide groove portion 540. Thereafter, with the movement of the first discharge stacker 1500 to the downstream side in the transport direction, the third protrusion 701 of the connection arm portion 700 is separated from the downstream end of the third groove portion 223 of the slider portion 550, and the third groove portion 223. Gradually move upstream. Accordingly, the discharge frame portion 800 is not affected by the second spring 922 at all.

  As shown in FIG. 33, when the pinion 219 further rotates in the clockwise direction from the state shown in FIG. 32, the pinion 219 attempts to move the first discharge stacker 1500 further downstream in the transport direction via the rack 227. . Accordingly, the first discharge stacker 1500 is guided by the engagement between the first protrusion 501 and the first groove 221 and further moved downstream in the transport direction while being guided by the engagement between the pinion 219 and the rack 227. To do. At this time, the third protrusion 701 of the connecting arm 700 moves the third groove 223 of the first discharge stacker 1500 to the upstream side in the transport direction, and reaches the upstream end of the third groove 223.

  As shown in FIG. 34, when the pinion 219 further rotates clockwise from the state shown in FIG. 33, the first discharge stacker 1500 further moves downstream in the transport direction. At this time, since the third protrusion 701 of the connecting arm unit 700 is in contact with the upstream end in the transport direction of the third groove 223 of the first discharge stacker 1500, the first discharge stacker 1500 is interposed via the connecting arm unit 700. Thus, the discharge frame portion 800 is moved downstream in the transport direction against the biasing force F1 of the first spring 921 described above.

  Further, the biasing force F <b> 1 of the first spring 921 exerts a force such that the third protrusion 701 of the connecting arm 700 pulls the upstream end of the third groove 223 of the first discharge stacker 1500 upstream. Therefore, the first discharge stacker 1500 generates a force that tries to rotate counterclockwise around a position that meshes with the pinion 219 in the rack 227. Then, the first protrusion 501 located on the opposite side of the third protrusion 701 with respect to the fulcrum is pressed against the lower surface of the first groove 221 by the force to rotate counterclockwise. Accordingly, the posture of the first discharge stacker 1500 can be further stabilized during movement.

  As shown in FIG. 35, when the pinion 219 further rotates clockwise from the state shown in FIG. 34, the pinion 219 tends to move downward along the sixth groove portion 226. In other words, the pinion 219 tries to move the first discharge stacker 1500 upward via the rack 227. At this time, due to the biasing force F <b> 1 of the first spring 921, a force is generated in the first discharge stacker 1500 to rotate counterclockwise around a position engaging with the pinion 219 in the rack 227. . Therefore, when the pinion 219 rotates in the clockwise direction, the first discharge stacker 1500 is tilted so that the downstream end of the first discharge stacker 1500 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 1500 is in contact with 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 places where the urging force F <b> 1 of the first spring 921 acts, is the rack 227. Is located between the portion meshing with the pinion 219 and the portion of the contact surface 520 that is in contact with the attitude regulating portion 228. Therefore, the posture restricting portion 228 abuts the counterclockwise rotation of the first discharge stacker 1500 around the pinion 219 in the rack 227 by the urging force F1 of the first spring 921 as a fulcrum. It can be regulated by contacting the surface 520.

As shown in FIG. 36, when the pinion 219 further rotates clockwise from the state shown in FIG. 35, the first discharge stacker 1500 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 sensor contact portion 544 pushes the protrusion 231 of the position detector 230 upward from below to turn it on.

  Further, the first discharge stacker 1500 is provided with a bifurcated position restricting means 560 that determines the position of the first discharge stacker 1500 at the second position. The position restricting means 560 includes a position restricting base 562 fixed to the first discharge stacker 1500, and a position restricting lever 561 that is rotatably provided and biased in a direction in which the fork is closed by a biasing means (not shown). ing. Then, as shown in FIG. 36, the position regulating lever 561 comes into contact with the shaft of the ejection drive roller 20a, and the position regulating lever 561 rotates in the direction in which the fork is opened against the urging force. The inclination, that is, the posture of the first discharge stacker 1500 at this time is a posture in which the CD-R tray guide surface 523 of the first discharge stacker 1500 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 1500 moves, the discharge frame portion 800 receives the urging force F1 of the first spring 921 and moves upstream in the transport direction.

  As shown in FIG. 37, when the pinion 219 further rotates clockwise from the state shown in FIG. 36, 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 1500 to the upstream side in the transport direction through the rack 227 in cooperation with the urging force F1 of the first spring 921. Accordingly, the first discharge stacker 1500 moves to the upstream side in the transport direction while being guided by the engagement between the first protrusion 501 and the first groove 221. That is, the posture of the first discharge stacker 1500 is regulated by the engagement between the first protrusion 501 and the first groove 221 and the engagement between the pinion 219 and the rack 227. 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).

The shaft of the ejection drive roller 20 a is sandwiched between the position restriction base 562 and the position restriction lever 561 of the position restriction unit 560. That is, the position and posture of the first discharge stacker 1500 are determined with high accuracy by the contact between the position restriction base 562 and the shaft of the discharge drive roller 20a.
Further, the second sensor contact portion 544 approaches the rotation fulcrum side of the protrusion 231 while being in contact with the lower side of the protrusion 231 of the position detector 230. Therefore, the protrusion 231 can be reliably pushed upward to be in the ON state.

  Further, as the first discharge stacker 1500 moves, the discharge frame portion 800 receives the urging force F1 of the first spring 921 and further moves upstream in the transport direction.

Further, the biasing force F1 of the first spring 921 exerts a force that causes the first discharge stacker 1500 to rotate counterclockwise around a position where the first discharge stacker 1500 is engaged with the pinion 219 in the rack 227. However, since the first protrusion 501 of the first discharge stacker 1500 is pressed against the lower portion of the first groove portion 221 of the base body 220, the first discharge stacker 1500 can hold the posture with high accuracy.
The lower portion of the second discharge driven rollers 503 and 503 of the first discharge stacker 1500 is in contact with the upper portion of the discharge drive roller 20a on the base portion side, and the first discharge stacker 1500 is part of the base portion. At first, the first motor 901 stops driving the pinion 219.

[Movement from Second Position to First Position of First Discharge Stacker According to Other Embodiment]
When the pinion 219 rotates counterclockwise from the state shown in FIG. 37, the pinion 219 tends to move along the sixth groove portion 226 to the upstream side in the transport direction. That is, the pinion 219 attempts to move the first discharge stacker 1500 to the downstream side in the transport direction against the urging force F1 of the first spring 921 via the rack 227. Accordingly, the first discharge stacker 1500 is guided by the engagement between the first protrusion 501 and the first groove 221 and moves downstream in the transport direction while being guided by the engagement between the pinion 219 and the rack 227. . At this time, the first discharge stacker 1500 translates downstream in the transport direction while maintaining the posture in which the CD-R tray guide surface 523 is parallel to the transport direction (Y). Accordingly, the shaft of the discharge drive roller 20a is released from the clamping between the position restriction base 562 and the position restriction lever 561 of the position restriction means 560. That is, the first discharge stacker 500 is released from the posture and position restriction by the position restriction means 560.
Further, as the first discharge stacker 1500 moves, the discharge frame unit 800 moves downstream in the transport direction.

  As shown in FIG. 36, when the pinion 219 rotates counterclockwise from the state shown in FIG. 37, the first discharge stacker 1500 moves downstream in the transport direction against the urging force F1 of the first spring 921. To do. At this time, the second discharge driven rollers 503 and 503 of the first discharge stacker 1500 are separated from the discharge drive roller 20a on the base portion side. Further, the abutting protrusion 521 of the first discharge stacker 1500 abuts on the attitude regulating portion 228 of the base body 220 that has been separated. The first protrusion 501 of the first discharge stacker 1500 is separated from the lower surface of the first groove part 221 by the shape of the first groove part 221. Accordingly, the biasing force F1 of the first spring 921 exerts a force that causes the first discharge stacker 1500 to rotate counterclockwise around a position where the first discharge stacker 1500 is engaged with the pinion 219 in the rack 227. . At this time, the posture of the first discharge stacker 1500 is regulated by the posture regulating unit 228 coming into contact with the contact projection 521. Further, the position restricting lever 561 of the position restricting means 560 rotates in the direction in which the fork is closed while being restricted by the shaft of the discharging drive roller 20a.

As shown in FIG. 35, when the pinion 219 further rotates counterclockwise from the state shown in FIG. 36, the first discharge stacker 1500 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 second sensor contact portion 544 is in a state of being separated from the lower side of the protrusion 231 of the position detector 230. Accordingly, the protrusion 231 can return to the neutral state, and the position detector 230 is turned off.

  As shown in FIG. 34, when the pinion 219 further rotates counterclockwise from the state shown in FIG. 35, 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 1500 to the upstream side in the transport direction through the rack 227 in cooperation with the urging force F1 of the first spring 921. Therefore, the first discharge stacker 1500 is guided by the engagement of the first protrusion 501 and the first groove 221 and moves upstream in the transport direction while being guided by the engagement of the pinion 219 and the rack 227. .

As shown in FIG. 33, when the pinion 219 further rotates counterclockwise from the state shown in FIG. 34, the first discharge stacker 1500 engages with the first protrusion 501 and the first groove 221, and the pinion 219 While being guided by the engagement with the rack 227, the upstream side in the transport direction is lowered and the downstream side is raised, and the upstream side is translated in parallel. Further, the discharge frame portion 800 moves with the movement of the first discharge stacker 1500, 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 come into contact with the upstream ends in the transport direction of the fourth groove portion 224 and the fifth groove portion 225 of the base portion 220, respectively, and the discharge frame portion 800 stops To do.
Further, since the position of the discharge frame portion 800 is the position that the discharge frame portion 800 takes when the first discharge stacker 1500 is at the first position, the urging force F1 of the first spring 921 is applied to the discharge frame portion 800. It is not acting against. Therefore, the urging force F1 of the first spring 921 does not act on the first discharge stacker 1500.

As shown in FIG. 32, when the pinion 219 further rotates counterclockwise from the state shown in FIG. 33, the first discharge stacker 1500 moves parallel to the upstream side in the transport direction. At this time, the third protrusion 701 of the connecting arm unit 700 moves away from the upstream end in the transport direction of the third groove 223 of the first discharge stacker 1500 and moves downstream.
Here, the first discharge stacker 1500 is provided so as to move parallel to the upstream side in the transport direction until the downstream end in the transport direction of the first discharge stacker 1500 is positioned upstream from the upstream end of the second discharge stacker 600.

  As shown in FIG. 31, when the pinion 219 further rotates counterclockwise from the state shown in FIG. 32, the first discharge stacker 1500 moves in parallel in the transport direction upstream. At this time, the third protrusion 701 of the connecting arm 700 moves to the downstream side in the transport direction of the third groove 223 of the first discharge stacker 1500 and contacts the downstream end of the third groove 223. Thereafter, when the first discharge stacker 1500 is further translated in the upstream in the transport direction, the slider portion 550 is restricted by the third protrusion 701. Accordingly, the slider portion 550 moves away from the upstream end 540a of the slider guide groove portion 540 in the transport direction with respect to the first discharge stacker 1500, and gradually moves the slider guide groove portion 540 toward the downstream side in the transport direction.

  At this time, since the length of the second spring 922 gradually increases, the urging force F2 of the second spring 922 gradually increases. Then, the increased urging force F <b> 2 of the second spring 922 acts toward the upstream side with respect to the discharge frame portion 800 via the connection arm portion 700.

As shown in FIG. 30, when the pinion 219 further rotates counterclockwise from the state shown in FIG. 31, the first discharge stacker 1500 further moves parallel to the upstream side in the transport direction.
At this time, since the slider portion 550 is regulated by the third protrusion 701, the slider portion 550 further moves the slider guide groove portion 540 to the downstream side in the transport direction with respect to the first discharge stacker 1500. Therefore, the urging force F2 of the second spring 922 acting on the discharge frame portion 800 further increases.

As shown in FIG. 29, when the pinion 219 further rotates counterclockwise from the state shown in FIG. 30, 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 1500 downward via the rack 227.
At this time, the slider portion 550 is closest to the downstream end of the slider guide groove portion 540. That is, the extension of the second spring 922 is the longest. Therefore, the urging force F2 of the second spring 922 acting on the discharge frame portion 800 becomes the maximum value. As a result, when moving from the second position to the first position, the discharge frame portion 800 can be reliably moved to the position to be taken.

As shown in FIG. 28, when the pinion 219 further rotates counterclockwise from the state shown in FIG. 29, the first discharge stacker 1500 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.
At this time, the slider portion 550 gradually moves to the upstream side in the transport direction of the slider guide groove portion 540. Accordingly, the urging force F2 of the second spring 922 acting on the discharge frame portion 800 gradually decreases.
Also, the first sensor contact portion 543 contacts the upper side of the protrusion 231 of the position detector 230, and rotates the protrusion 231 downward. Accordingly, the position detector 230 is turned on.

As shown in FIG. 27, when the pinion 219 further rotates counterclockwise from the state shown in FIG. 28, the first discharge stacker 1500 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. At this time, when the first discharge stacker 1500 reaches a part of the base portion 220, the driving of the first motor 901 is stopped and the rotation of the pinion 219 is stopped. Accordingly, the first discharge stacker 1500 is accurately positioned at the first position.
In addition, the first sensor contact portion 543 rotates the protrusion 231 of the position detector 230 further downward, so that the position detector 230 is reliably turned on.

As described above, the discharge stacker elevating device 1200 includes the first spring 921 as the first urging means and the second spring 922 as the second urging means, divided for each role. Therefore, desired urging forces F1 and F2 can be obtained at a desired timing according to the purpose. As a result, the load on the first motor 901 can be reduced as compared with the embodiment described above.
In another embodiment, since the first discharge stacker 1500 includes the slider portion 550, the first spring 921 and the second spring 922 can be configured not to act simultaneously. As a result, the load on the first motor 901 can be further reduced.

In the discharge stacker lifting / lowering device 1200 according to another embodiment, the biasing means 805 for biasing the discharge frame portion 800 toward the position where the first discharge driven roller 20b and the discharge drive roller 20a cooperate with each other is the first.
