When the thickness of the paper P is changed or when the paper recording mode for recording the paper P is changed to the CD-R recording mode for recording the CD-R label surface, the cam shaft 302 is rotated by the APG motor 910. 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.

The posture is regulated by 410. That is, the planetary gear holder 420 is in a restricted state. 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.

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. 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.

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 feed motor 920 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 feed motor 920 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, so that the count of the number of steps of the feed motor 920 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 pinion 219 is stopped at the timing when the first discharge stacker 500 is separated from the home position detector 230 as described above, and the feed motor 920 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. 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 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 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 feed motor 920, 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 in the CD-R tray guide opening of the first discharge stacker.

[Recorder gap adjustment device]
Next, the recording unit gap adjusting device will be described.
FIG. 27 is a perspective view showing a recording unit gap adjusting apparatus according to the present invention. FIG. 28 is a schematic side view showing power transmission of the recording unit gap adjusting apparatus according to the present invention.
As shown in FIGS. 27 and 28, the recording unit gap adjusting apparatus 300 includes an APG (auto platen gap or auto paper gap) motor 910 as a first driving unit. The driving force of the APG motor 910 is generated from a pinion gear attached to the APG motor 910 via a first transmission gear 307, a second transmission gear 308, a pump unit 309, a pendulum gear 310, and an APG reduction wheel train 311. 301. When the PG adjustment cam portion 301 is rotated by being supported by the cam receiving portion 312 provided in the base portion 220, the carriage guide shaft 12 provided eccentrically with respect to the PG adjustment cam portion 301 as described above is moved in the vertical direction. It is provided to move to.

Further, as described above, when the PG adjustment cam portion 301 rotates, the lock lever 410 moves via the lever member 304 and the slide bar 430, and the power transmission switching device 400 is switched between connection and disconnection of power transmission. It is configured as follows. That is, the recording unit gap adjusting device 300 is configured to switch connection / disconnection of the power transmission state for moving the first discharge stacker 500 of the discharge stacker lifting / lowering device 200 to the first position and the second position. Has been.
In FIG. 28, when the gear of the pump unit 309 rotates counterclockwise, the inside of the cap unit is sucked to be negative pressure.

FIG. 29 is a timing chart of the recording unit gap adjusting device and the power transmission switching device. In the vertical axis, the PG for the PG adjustment cam portion, the planetary gear holder portion state for the power transmission switching device, that is, the power transmission state,
“Wheel” indicates the presence or absence of sensor detection. On the other hand, the horizontal axis represents the rotation of the PG adjustment cam portion from 0 ° to 360 °.
The Flag Wheel (not shown) is provided so as to rotate according to the rotation of the PG adjustment cam portion.

First, when the PG adjustment cam portion 301 is at a position of 0 °, PG is 1.2 mm, the planetary gear holder portion 420 is in a restricted state, that is, power transmission is in a disconnected state, and Flag Wheel is not detected.
When the PG adjustment cam portion 301 rotates 7.5 ° in a predetermined direction from the 0 ° position, a sensor (not shown) detects a flag wheel (not shown). Here, the sensor is provided so as to be ON while the PG adjustment cam portion 301 further rotates by 20 ° with a constant width. In other words, when “PG- (small)” is selected by the control unit 900, the PG adjustment cam unit 301 is provided to stop within the range of 20 °.

During a further 30 ° rotation, the sensor is turned off, during which PG changes to 1.7 mm. During a further 19 ° rotation, the sensor is on. This state is “PGtyp (standard)”.
During a further 32 ° rotation, the sensor is turned off, during which PG changes to 2.35 mm. During a further 19 ° rotation, the sensor is on. This state is “PG + (large)”.

  Then, the sensor is turned off while rotating 63 ° further, and PG changes to 4.2 mm during that time. Further, the planetary gear holder 420 is in a released state, that is, power transmission is in a connected state. During a further 10 ° rotation, the sensor is turned on. This state is the “CDR” state. That is, the feed motor 920 as the power source of the discharge drive roller 20a moves the first discharge stacker 500 of the discharge stacker lifting / lowering device 200 to the first position and the second position via the power transmission switching device 400. Mode.

During the further 59 ° rotation, the sensor is turned off, and the planetary gear holder 420 is in the restricted state, that is, the power transmission is cut off. During a further 15 ° rotation, the sensor is on. This state is “PG ++ (CDR recording mode)”. When the sensor further rotates by 85.5 °, the sensor is turned off and returns to the state of 0 ° (360 °) again.
In FIG. 29, the angle indicated in parentheses is the rotation angle of Flag Wheel. Because the PF adjustment cam part swings, Flag
There is a slight difference in the rotation angle between the wheel and the PG adjustment cam portion 301.

  30 and 31 are charts showing the operation of the recording unit gap adjusting apparatus. Of these, FIG. 30 shows a state in which the recording unit gap adjusting device automatically operates as determined by the control unit. On the other hand, FIG. 31 shows a state in which the recording unit gap adjusting device is operated according to a user instruction and the discharge stacker lifting device is operated.

  As shown in FIG. 30, when the recording unit gap adjusting apparatus 300 operates automatically as determined by the control unit 900, first, in step 11 (hereinafter simply referred to as S11), recording data is received from the host. Specifically, the control unit 900 of the recording apparatus 100 receives recording data sent from a PC used by a user or the like. Then, the process proceeds to S12.

  In S12, it is determined whether or not recording can be executed with the current PG. That is, the control unit 900 determines whether or not it is necessary to change and adjust the PG in order to execute the recording of the recording data received in S11. If it is determined that the current PG cannot be executed and the change is necessary, the process proceeds to S13. On the other hand, if it is determined that the process can be executed with the current PG and no change is necessary, the process proceeds to S14.

In S13, the automatic PG operation is executed to the target PG in the low speed mode. Specifically, the APG motor 910 is driven at a low speed, and the PG change adjustment is executed at a low speed. Since it is performed at low speed, it can be calmed down. Furthermore, the stop position of the PG adjustment cam portion 301, that is, the phase when stopped can be determined with high accuracy. At this time, the process proceeds to S14.
In S14, recording is executed. Specifically, recording is performed on paper P, CD-R, etc. based on the recording data received in S11. And it ends.

  As shown in FIG. 31, when the recording unit gap adjusting device 300 operates according to a user instruction and operates the discharge stacker lifting device 200, first, data is received from the front panel 6 in S21. Specifically, the control unit 900 receives information as an instruction that the user has pressed the operation button 8 on the front panel 6. For example, regarding the CDR guide operation, it is instruction information for executing the movement of the first discharge stacker 500. Then, the process proceeds to S22.

In S22, it is determined whether or not the power transmission state of the power transmission switching device 400 is a connected state. Specifically, the Flag described above with reference to FIG.
If the wheel is detected by the sensor as the “CDR” state, the planetary gear holder unit 420 is in the released state, so that the power transmission is determined to be in the connected state. On the other hand, the flag wheel is in a state where the sensor is other than “CDR”, that is, in a state of “PG− (small)”, “PGtyp (standard)”, “PG + (large)” or “PG ++ (CD-R recording mode)”. , The planetary gear holder portion 420 is in a restricted state, so that power transmission is determined to be in a disconnected state. And when it is judged that it is a cutting state, it progresses to S23. On the other hand, if it is determined that the connection is established, the process proceeds to S24.

In S23, the automatic PG operation is executed to a position where the power transmission state of the power transmission switching device 400 is in the connected state in the high speed mode. Specifically, the APG motor 910 is driven at a high speed, and the PG adjustment cam unit 301 is rotated at a high speed. And the sensor is Flag
The PG adjustment cam unit 301 is stopped at a position where the wheel is detected as the “CDR” state. Therefore, the power transmission state of the power transmission switching device 400 is a connected state. Then, the process proceeds to S24.

  In S24, a CDR guide operation is executed. Specifically, as described above, the driving force of the feed motor 920 moves the first discharge stacker 500 of the discharge stacker lifting / lowering device 200 to the first position and the second position via the power transmission switching device 400. Let Then, the process proceeds to S25.

In S25, the automatic PG operation is executed to a position where the power transmission state of the power transmission switching device 400 is in the disconnected state in the high speed mode. Specifically, the APG motor 910 is driven at a high speed, and the PG adjustment cam unit 301 is rotated at a high speed. Then, in order to put the planetary gear holder 420 in the restricted state, the sensor is flagged.
The PG adjustment cam unit 301 is stopped at a position where the wheel is detected as a state other than “CDR”. At this time, it is normally provided so as to return to the “PG- (small)” state. When the next recording data can be determined in advance, it is desirable to execute the automatic PG operation so as to obtain a PG suitable for it.

For example, when the first discharge stacker 500 moves from the first position to the second position in S24 and the next recording data is CDR data to be recorded on the CD-R label surface, the sensor is flagged.
It is desirable that the PG adjustment cam unit 301 is stopped at a position where the wheel is detected as the “PG ++ (CDR recording mode)” state.
On the other hand, when the first discharge stacker 500 moves from the second position to the first position and the next recording data is execution of recording on plain paper, the sensor is flagged.
It is desirable that the PG adjustment cam unit 301 is stopped at a position where the wheel is detected as the “PG- (small)” or “PGtyp (standard)” state.
And it ends.

As described above, in S23, since the power transmission state of the power transmission switching device 400 is switched to the connected state in the high speed mode, compared with the case of switching in the low speed mode, the first discharge in S24 from the user instruction in S21 The response until the operation of the stacker 500 is started can be improved. In other words, in the configuration in which the first discharge stacker 500 moves using the recording unit gap adjusting device 300 as a trigger, the response until the operation of the first discharge stacker 500 can be improved.
As a result, the waiting time of the user can be shortened.

Further, by driving the APG motor 910 at a high speed from the user instruction in S21 to the start of the operation of the first discharge stacker 500 in S24, the driving sound of the APG motor 910 is increased moderately and operates inside the recording apparatus. Can appeal to the user. That is, there is a time lag between the user instruction in S21 and the start of the operation of the first discharge stacker 500 in S24. By appealing the operation of the APG motor 910 in the recording apparatus in S23, the overall response of the recording apparatus is good. You can appeal that.
As a result, a sense of security can be given to the user.
