<Overall configuration of inkjet printer>
First, an ink jet printer (hereinafter referred to as “printer”) 100 as a recording apparatus according to the present embodiment will be described with reference to FIGS. 1 to 3. Here, FIG. 1 is a side sectional view of the printer 100, and FIG. 2 is a first transport path “maru 1” (in this specification, “maru 1” is described in FIGS. 1 and 2). 3 is an enlarged side cross-sectional view showing a state in which recording is performed on a sheet using the numeral “1” surrounded by a circle. , “Mal 2” (in this specification, “Mal 2” refers to the circled number “2” as described in FIG. 3). It is a principal part expanded side sectional view which shows the state which is recording the rigid recording material.
Here, the recording material that can be fed in a curved posture using the paper feeding device 2 as the recording material feeding device is “paper P”, and the recording material that cannot be fed and discharged in the curved posture is “ Rigid recording material G ”and these may be combined to form“ recording material ”.

  The printer 100 is provided with a paper feeding device 2 for supplying the paper P on the upstream side. The paper feeding device 2 accumulates and holds the paper P in an inclined posture, and feeds the paper P to the downstream side while curving one by one. A first feeding path “Maru 1” (FIGS. 1 and 2) that discharges substantially horizontally from the front side, and a rigid recording material G that cannot use such a curved feeding path are substantially horizontal from the front side. And a second feeding path “Maru 2” (FIG. 3) for discharging from the front again.

First, a sheet feeding operation using the first feeding path “Maru 1” will be described with reference to FIGS. 1 and 2, and operations of the constituent members will also be described with reference to FIG. 3 as appropriate.
The sheet feeding device 2 includes a hopper 16, and a plurality of sheets P are stacked and held on the hopper 16 in an inclined posture. The hopper 16 includes a rotation fulcrum (not shown) on the upstream side thereof, and rotates around the rotation fulcrum to perform separation and pressure-contacting operations toward the paper feed roller 14 that is substantially D-shaped in side view. It is configured to be able to do. The accumulated paper P is pushed up by the pressing operation toward the paper feed roller 14 of the hopper 16, and the uppermost one of the paper P is brought into pressure contact with the paper feed roller 14. In this state, the paper P is fed downstream by rotating the paper feed roller 14.

  A plate-shaped paper guide 15 is provided almost horizontally below the paper feed roller 14, and the leading edge of the paper P fed from the paper feeding device 2 comes into contact with the paper guide 15, and smoothly Curved and guided downstream.

  Downstream of the paper guide 15 is disposed a conveyance roller 19 composed of a conveyance drive roller 19a that is rotationally driven by a driving means (not shown) and a conveyance driven roller 19b that is rotated in contact with the conveyance drive roller 19a. The sheet P is narrowed by the conveying roller 19 and conveyed downstream. The transport driving roller 19a is composed of a rod-like roller that is long in the main scanning direction. On the other hand, a plurality of transport driven rollers 19b are short in the main scanning direction and arranged at predetermined intervals in the main scanning direction. .

  The conveyance driven roller 19b is pivotally supported on the downstream side of the conveyance driven roller holder 18. The conveyance driven roller holder 18 is provided so as to be rotatable about a rotation shaft 18a, and a torsion coil spring (not shown). ) Is urged to rotate so that the conveyance driven roller 19b is always in pressure contact with the conveyance drive roller 19a and comes into a contact state to be described later.

  The transport driven roller 19b is driven by a second link mechanism as a transport driven roller switching means described later, so that the transport driven roller holder 18 rotates about its rotation fulcrum 18a, thereby transporting the transport driven roller 19b. The contact state (FIG. 2) in contact with the drive roller 19b and the retracted state (FIG. 3) retracted upward can be switched.

  More specifically, the cam rotation shaft 31 is provided so that the cam portion 36 abuts the cam follower portion 18b on the upstream side of the conveyance driven roller holder, and the cam rotation shaft 31 rotates. The cam portion 36 comes into contact with the cam follower portion 18b from above, and the conveyance driven roller holder 18 rotates about the rotation fulcrum 18a, whereby the conveyance driven roller 19b retreats upward, as shown in FIG. Thus, the retreat state is established. When the contact of the cam portion 36 with the cam follower portion 18b is released, the transport driven roller 19b is urged to rotate toward the transport drive roller 19a by a torsion coil spring (not shown), and the configuration shown in FIG. As shown, the contact state is established. The configuration of the second link mechanism that rotates the cam rotation shaft 31 will be described later.

  Further on the downstream side, a recording unit 26 for recording on a sheet is configured. The recording unit 26 is arranged such that the platen 28 and the recording head 13 face each other in the vertical direction. The platen 28 is configured to be long in the main scanning direction, and can support the sheet P conveyed to the recording unit 26 from below.

  The recording head 13 is provided at the bottom of the carriage 10, and the carriage 10 can reciprocate in the main scanning direction while being guided by a carriage guide shaft 12 extending in the main scanning direction. In addition, the carriage 10 includes ink cartridges 11 such as yellow, magenta, cyan, and black, and is configured to perform full color recording.

  The distance between the platen 28 and the recording head 13 (hereinafter referred to as “PG”) is an important factor that affects the recording accuracy, and therefore needs to be appropriately adjusted according to the thickness of the recording material. Accordingly, a first link mechanism is provided as PG adjusting means for displacing the carriage guide shaft 12 in the vertical direction. The configuration of the first link mechanism will be described later.

  A downstream side of the recording unit 26 is a paper discharge unit for the paper P in the printer 100, and a paper discharge drive roller 20a that is rotationally driven by a driving unit (not shown) and a light pressure contact with the paper discharge drive roller 20a. A paper discharge roller 20 including a paper discharge driven roller 20b that is driven to rotate is provided. Then, the paper P on which recording has been performed by the recording unit 26 is discharged onto the recording material stacker 50 by the paper discharge driving roller 20a rotating (forward rotation) while being narrowed by the paper discharge roller 20. It has become.

  The paper discharge driven roller 20 b is a toothed roller having a plurality of teeth on its outer periphery, and is supported by a paper discharge driven roller holder 23 so as to be freely rotatable. The paper discharge driven roller holder 23 is formed of a plate-like body that is long in the main scanning direction, and extends substantially horizontally from the vicinity of the downstream side of the recording head 13 toward the downstream side when viewing the paper discharge path of the paper P. 25 is fixed. Similarly, the discharge subordinate frame 25 is long in the main scanning direction and extends from the vicinity of the downstream side of the recording head 13 to the discharge main frame 24 formed of a plate-like body from the upper side by a coil spring 27 from above. It is attached in a state where it is pressed.

  A paper discharge auxiliary roller 22 is provided upstream of the paper discharge driven roller 20 b, and the paper P is pressed slightly downward by the paper discharge auxiliary roller 22. Further, the transport driven roller 19b is disposed at a position slightly downstream of the transport drive roller 19a, and the discharge driven roller 20b is disposed at a position slightly upstream of the transport drive roller 20a. It is arranged on the side. With such a configuration, the sheet P is curved in a slightly convex shape between the transport roller 19 and the sheet discharge roller 20, and the sheet P at a position facing the recording head 13 is pressed against the platen 28. As a result, the sheet P is prevented from being lifted, and the recording is normally executed.

  The paper discharge auxiliary roller 22 is constituted by a toothed roller, like the paper discharge driven roller 20b, and is pivotally supported by the paper discharge auxiliary roller holder 21. The paper discharge auxiliary roller holder 21 is fixed to the paper discharge follower frame 25 in the same manner as the paper discharge driven roller holder 23 described above.

  Further, the paper discharge slave frame 25 rotates about the upstream side 25c as a rotation center when a cam 29a provided on a holder rotation shaft 29, which will be described later, rotates and comes into contact with the lower side. Can be done. That is, the discharge subordinate frame 25 can take a state (FIG. 2) parallel to the immediate upper side of the discharge main frame 24 and a state where the discharge side subframe 25 is rotated and the downstream side is lifted (FIG. 3). It is configured.

  With such a configuration, the paper discharge driven roller holder 23 and the paper discharge auxiliary roller holder 21 fixed to the paper discharge follower frame 25 rotate together with the paper discharge follower frame 25, so that the paper discharge driven roller 20b and The paper discharge auxiliary roller 22 can be retracted upward. As a result, as shown in FIG. 3, the following problems that may occur when the recording material is thick (rigid recording material G) and is a CD-R, for example, can be prevented. it can. Since the paper discharge driven roller 20b and the paper discharge auxiliary roller 22 described above are toothed rollers, the teeth come into point contact with the recording surface of the CD-R, and are configured immediately below the recording surface of the CD-R. There is a risk of destroying information by acting on the information storage portion. In order to prevent such a problem, when the recording material is a CDR, the discharge driven roller 20b and the discharge auxiliary roller 22 are retracted upward so as not to contact the recording surface of the CDR. That is, the state can be changed according to the type of recording material.

  The discharged paper P is stacked on the recording material stacker 50 whose recording material placement surface 51 is inclined (second position). As shown in FIG. 3, when recording the rigid recording material G, the recording material stacker 50 is positioned at the first position where the recording material placement surface 51 is substantially horizontal. The configuration and operation of the recording material stacker 50 will be described later.

The engaging shaft 52 engages with a side surface of the operating member 40 that is an engaged member. ing. The operating member 40 is formed in a “U” shape that is convex upward when viewed from the downstream side. Therefore, when the recording material stacker 50 displaces the position, the operating member 40 can also be displaced in the vertical direction in conjunction (following). The operating member 40 is guided from both side surfaces by guide plates 60 fixed to a main body frame (not shown), and is displaced along the inner surface of the guide plate 60 in the vertical direction. It is.

  The facing side of the actuating member 40 engaged with the recording material stacker 50 serves as a power transmission member that transmits power to the rotating body 43 having the eccentric bush portion 44 that supports the carriage guide shaft 12. The first transmission component 41 is engaged. The first transmission component 41 is rotatable with respect to the operation member 40 with the engaging portion 41a with the operation member 40 as a rotation center. Further, the first transmission component 41 is engaged with the second transmission component 42 that connects the rotating body 43 at the engaging portion 42 a.

  The rotating body 43 pivotally supports the carriage guide shaft 12 at a position deviated from its rotation center via the eccentric bush portion 44. With such a configuration, when the rotating body 43 is rotated by the switching operation of the recording material stacker 50, the carriage guide shaft 12 pivotally supported at a position deviated from the rotation center of the rotating body 43 is displaced in the vertical direction. PG can be adjusted.

  That is, when the recording material stacker 50 is in the first position, the carriage guide shaft 12 is displaced vertically upward so that PG is increased, and further, the recording material stacker 50 is in the second position. In the position state, the carriage guide shaft 12 is displaced vertically downward, so that PG is reduced.

Next, the second link mechanism will be described.
In the present embodiment, by operating the operation lever 32 as an operation unit, the transport driven roller 19b is displaced in a substantially vertical direction, and the transport driven roller 19b is in contact with the transport drive roller 19a ( 2) and a retracted state (FIG. 3) retracted upward can be switched.

  The operation lever 32 is configured to be rotatable about a rotation shaft 32a and is engaged with the third transmission component 33 on the upstream side 33a thereof. The operation lever 32 is configured to be rotatable with respect to the third transmission component 33 at an engaging portion 33a with the third transmission component 33 when rotated about the rotation shaft 32a. ing.

  The third transmission component 33 is engaged with the fourth transmission component 34 that supports the cam rotation shaft 31 on the upstream side 33b. With such a configuration, when the operating lever 32 is rotated downstream (clockwise), the third transmission component 33 is pulled downstream, whereby the fourth transmission that supports the cam rotation shaft 31 is provided. As described above, the member 34 rotates, and the cam portion 36 comes into contact with the transport driven roller holder 18 that pivotally supports the transport driven roller 19b, thereby bringing the transport driven roller 19b into a retracted state.

  The operation lever 32 is disposed in a space formed on the inner side of the operating member 40. Therefore, when the recording material stacker 50 is located at the second position, its rotation is restricted. The operation member 40 can be operated only when it is displaced upward, that is, when the recording material stacker 50 is located at the first position.

  That is, when the recording material stacker 50 is in the first position, the operation lever 32 can be operated as shown in FIGS. 7 and 8, and accordingly, the transport driven roller 19b is in the contact state or the retracted state. can do. Further, when the recording material stacker 50 is in the second position, as shown in FIG. 9, the operation lever 32 cannot be operated, so that the transport driven roller 19b comes into contact. Yes.

  Here, driving of the first link mechanism and the second link mechanism will be described. For convenience of explanation, the description will be made based on the operation of the recording material stacker 50, and when the recording material stacker 50 is displaced from the second position state (FIG. 9) to the first position (FIGS. 7 and 8), The case of displacement from the first position (FIGS. 7 and 8) to the second position (FIG. 9) will be described.

  First, as shown in FIG. 9, the recording material stacker 50 is positioned at the second position, and the recording material placement surface 51 which is the upper surface thereof is in an inclined state. At this time, the carriage guide shaft 12 is lowered downward, and the recording material stacker 50 can stack the discharged paper P on the recording material placement surface 51 on the upper surface thereof. Is possible. Accordingly, recording can be performed on the sheet supplied from the above-described sheet feeding device 2 via the first feeding path “Maru 1”, and the conveyance driven roller 19b is in contact with the conveyance driving roller 19a. It is in contact. As a result, the paper P is transported to the recording unit 26 while being narrowed by the transporting roller 19 to perform recording, and is stacked on the recording material placing surface 51.

  When the recording material stacker 50 is located at the second position, the operation lever 32 cannot be rotated by the operating member 40, that is, cannot be operated. That is, the upstream side of the rotation shaft 32a of the operation lever 32 is restricted from above by the operating member 40, and cannot be rotated. Accordingly, the operation lever 32 cannot be operated to drive the second link mechanism. For this reason, the conveyance driven roller 19b always carries the conveyance driving roller 19a when the recording material stacker 50 is located at the second position. The contact state is in contact with the.

  Then, when the recording material stacker 50 is moved upward to be displaced from the second position to the first position (FIG. 7), the operating member 40 is also moved upward and displaced upward. As a result, the engaging portion 41a between the operating member 40 and the first transmission component 41 is also displaced upward, and the first transmission component 41 rotates upstream (counterclockwise) in conjunction with the engagement portion 41a. Move. This power is transmitted by the second transmission member 42, and the rotating body 43 is rotated, and the carriage guide shaft 12 that is pivotally supported at a position deviated from the rotation center is displaced vertically upward, and PG is To adjust.

  That is, when the carriage guide shaft 12 is displaced upward, the distance between the recording head 13 and the platen 28 is larger than when the recording material stacker 50 is positioned at the second position.

  When the recording material stacker 50 is moved to the first position and the operation member 40 is also displaced upward, the restriction of the operation lever 32 by the operation member 40 is released, and the operation lever 32 is operated. This is possible (FIG. 7).

  Then, the third transmission component 33 is pulled to the downstream side by rotating the operation lever 32 upstream (clockwise) about the rotation shaft 32a as a rotation center, thereby the cam rotation. As described above, the fourth transmission member 34 that pivotally supports the moving shaft 31 rotates, and the cam portion 36 contacts the conveyance driven roller holder 18 that pivotally supports the conveyance driven roller 19b. The conveyance driven roller 19b is set in the retracted state.

  As a result, the rigid recording material G is manually fed using the second feeding path “Maru 2” which is fed substantially horizontally from the recording material placement surface 51 toward the recording unit 26 and then discharged again. It becomes possible to do. After the rigid recording material G can be narrowed by the conveying roller 19, the second link mechanism is driven to bring the conveying driven roller 19b into a contact state, whereby the rigid recording material G is conveyed. The pressure is reduced by the roller 19 so that it can be conveyed.

  The recorded rigid recording material G is discharged again onto the recording material placement surface 51 through the second feeding path “maru 2”. When recording is continuously performed on the rigid recording material G, after the rigid recording material G is discharged, the transport driven roller 19b is in contact with the second link mechanism again. , And the conveyance driven roller 19b is retracted, and then the rigid recording material G is manually fed. Therefore, when the recording material stacker 50 is in the first position, the operation lever 32 can be operated alone to change the state of the transport driven roller 19b as appropriate.

  Next, by lowering the recording material stacker 50 downward, the recording material stacker 50 is displaced from the first position to the second position, thereby acting on the first link mechanism. And the actuating member 40 is lowered. As a result, the engaging portion 41a between the actuating member 40 and the first transmission component 41 is also displaced downward, and the first transmission component 41 is rotated downstream (clockwise) with the engaging portion 41a as a rotation center. Move. This power causes the rotating body 43 to be rotated by the second transmission member 42 to displace the carriage guide shaft 12 pivotally supported at a position deviated from the rotation center in the vertically downward direction.

  When the recording material stacker 50 is displaced from the first position to the second position, the operation lever 32 is pivoted upstream (FIG. 8), that is, the transport driven roller 19b is in the retracted state. In the state, the recording material stacker 50 is displaced to the second position, so that the operating member 40 acts on the second link mechanism as a push-back means to bring the transport driven roller 19b into a contact state. It can be done.

  That is, when the recording material stacker 50 is in the first position and the transport driven roller 19b is in the retracted state, the operation lever 32 of the second link mechanism is rotated upstream (FIG. 8). Therefore, the operating member 40 as the push-back means is located above the upstream side 32b of the operation lever 32. When the recording material stacker 50 is displaced from this state to the second position, the operating member 40 also follows and descends, whereby the operating lever upstream side 32b is urged by the operating member 40 from above. Then, following the lowering of the operating member 40, the operation lever 32 is rotated upstream (counterclockwise).

  Accordingly, the actuating member 40 acts on the second link mechanism as a push-back means for pushing back the operation lever 32 and a restricting means for restricting the driving of the second link mechanism, thereby bringing the transport driven roller 19b into a contact state. it can. In other words, when the recording material stacker 50 is located at the second position, the transport driven roller 19b is always in contact with the transport drive roller 19a.

  In addition, the second link mechanism as the transport driven roller switching unit described above can be driven in conjunction with the movement of the first link mechanism. In such a case, it is possible to appropriately set conditions that are optimal for recording a recording material that is a recording target, only by the user operating the recording material stacker 50.

  As described above, according to the present invention, since the first link mechanism for displacing the carriage guide shaft in conjunction with the displacement of the recording material stacker is provided, it is only necessary to operate the recording material stacker. PG can be adjusted according to the recording material.
