Description

  The present invention relates to a recording apparatus such as an ink jet printer that performs recording by ejecting ink droplets onto a recording material such as recording paper, and also relates to a liquid ejecting apparatus that causes liquid to adhere to the ejection material.

  Here, the liquid ejecting apparatus uses an ink jet recording head, and is not limited to a recording apparatus such as a printer, a copying machine, and a facsimile machine that discharges ink droplets from the recording head to record on a recording material. And a device for ejecting the liquid corresponding to the application from the liquid ejecting head corresponding to the recording head to the ejected material corresponding to the recording material and attaching the liquid to the ejected material. In addition to the recording head, as a liquid ejecting head, a colorant ejecting head used for manufacturing a color filter such as a liquid crystal display, an electrode material (conductive paste) used for forming an electrode such as an organic EL display or a surface emitting display (FED) Examples thereof include an ejection head, a bioorganic matter ejection head used for biochip production, and a sample ejection head as a precision pipette.

  One of the recording apparatus and the liquid ejecting apparatus is an ink jet printer. The ink jet printer is provided on the upstream side of the recording material conveyance path, and feeds recording materials (for example, plain paper, postcards, envelopes, etc.) accumulated and held in an inclined posture to the downstream side one by one. Recording material feeding device, a recording head provided on the downstream side of the recording material feeding device, for recording by discharging ink droplets toward the recording material, and provided on the downstream side of the recording head And a paper discharge roller for discharging the recording material on which recording has been performed. The paper discharge roller is provided on a non-recording surface side (that is, the back surface side) of the recording material, and on a recording surface side (that is, the front surface side) of the recording material. And a discharge driven roller composed of a toothed roller having a plurality of teeth.

  Incidentally, recent inkjet printers are configured to perform recording on various recording materials such as postcards, envelopes, cardboard boards, CD-Rs (writable compact discs) in addition to plain paper. Yes.

  Among these recording materials, when recording on a flexible paper such as plain paper, postcard, envelope, etc., which can be fed in a curved posture (hereinafter referred to as “paper”), After the recording material is fed from the recording material feeding device and recorded by the recording head, the paper is discharged to a recording material stacker provided on the front side of the device (on the downstream side of the conveyance path) by a paper discharge roller. A first transport path fed in the direction is used. On the other hand, when recording is performed on a cardboard board, a CD-R, or the like having rigidity (hereinafter referred to as “rigid recording material”), it is difficult to feed depending on the recording material feeding device. Alternatively, since the recording material stack G is fed to the recording head from the recording material stacker in front of the apparatus and recorded, the recording material stacker discharges the recording material stacker again. A linear second transport path for reciprocally transporting is used.

  For example, when recording is performed on a CD-R using the second transport path, it is necessary to avoid contact of the discharge driven roller with the CD-R. This is due to the occurrence of contact traces caused by the contact of the paper discharge driven roller composed of the toothed rollers with the upper surface which is the recording surface of the CD-R, and the influence on the data storage layer (for example, data Is stored, the data is destroyed, and when the data is not stored, the data cannot be stored at the contact point.

  Therefore, when the paper discharge driven roller is attached to the paper discharge frame and the paper discharge frame is displaced to perform recording on paper such as plain paper, the paper discharge driven roller is brought into contact with the paper discharge driving roller. When the recording is performed on a rigid recording material such as a CD-R, the discharge driven roller is configured to be maintained in a retracted state in which it is retracted from the recording material conveyance path. Yes. As described above, there has been reported a recording apparatus that displaces the discharge driven roller according to the purpose of printing (see, for example, Patent Document 1).

JP 2002-192882 A

Further, when recording is performed on a rigid recording material such as a CD-R using the second transport path, an operation lever for retracting the paper discharge frame is separately provided in the apparatus. .
However, each time printing is performed on a rigid recording material, it is cumbersome to operate the operation lever, and when the user erroneously operates the operation lever to perform printing on the rigid recording material. In such a case, there is a risk of causing the above-described problems.

Recording can be performed under conditions. Therefore, for example, in the case of a recording material that causes a problem by contacting with the discharge driven roller during the recording operation, the discharge driven roller is moved out of the recording material conveyance path by setting the recording material stacker to the first position. Therefore, the recording operation can be performed while reliably avoiding contact with the discharge driven roller. On the other hand, when the recording material is preferably brought into contact with the discharge driven roller during the recording operation, the discharge driven roller is positioned in the recording material conveyance path by setting the recording material stacker to the second position.

Therefore, when the recording material stacker is in the second position, the discharge driven roller is configured to take the position in the contact state.

  According to this feature, when the first recording material or the second recording material is selected as the recording material, recording can be performed under conditions suitable for each recording material. That is, when the first recording material is selected as the recording material, the discharge driven roller can be positioned outside the recording material conveyance path by setting the recording material stacker to the first position. It is possible to carry and carry the recording operation while reliably keeping the non-contact state between the one recording material and the discharge driven roller. On the other hand, when the second recording material is selected, the discharge driven roller can be positioned in the recording material conveyance path by setting the recording material stacker to the second position. The conveying and recording operations can be performed while the contact state between the toner and the discharge driven roller is reliably maintained.

FIG. 2 is a partially omitted side view of the printer 1 and shows a state in which printing (recording) is performed on the rigid recording material G using a second conveyance path “maru 2” to be described later. It is a thing.

  Here, as a second recording material recorded in contact with a discharge driven roller as a discharge driven roller, which will be described later, a sheet feeding device 2 as a recording material feeding device, which will be described later, is used to feed in a curved posture. A recording material that can be fed (for example, a flexible recording material such as plain paper, a postcard, and an envelope) is referred to as “paper P”, and is not in contact with a discharge driven roller as a discharge driven roller described later. As a first recording material to be recorded in a state, a recording material that is difficult or impossible to feed in a curved posture (for example, a rigid recording material such as a CD-R or a cardboard board) is used as a “rigid material”. This may be referred to as “recording material G” and may be collectively referred to as “recording material”.

  As shown in FIG. 1, the printer 1 is provided with a paper feeding device 2 that supplies the paper P on the upstream side of the recording material conveyance path on the rear side of the device (the right hand side in FIG. 1). The paper P is accumulated and held in an inclined posture by 2 and fed to the downstream side while being bent one by one and printed, and then discharged in a substantially horizontal posture from the front side of the apparatus (the left hand side in FIG. 1). As shown in FIG. 2, the first conveyance path “Maru 1” for feeding the paper P in one direction, and the recording material stacker 50 disposed on the front side of the apparatus as a rigid recording material G are substantially horizontal. In addition, a linear second transport path “Maru 2” for reciprocally transporting the rigid recording material G, which is fed toward the recording head 13 and printed and then discharged to the front side of the apparatus again, is provided. is doing.

When the paper P or the rigid recording material G is used as the recording material, the distance between the recording head 13 and the platen 28 (so-called platen gap, hereinafter referred to as “platen gap”) is changed by changing the position according to the thickness of the recording material. It may be indicated as “PG”).

  That is, since the recording quality is greatly influenced by the paper gap, which is the distance between the recording surface of the recording material conveyed on the platen 28 and the recording head 13, the size of the platen gap is considered in consideration of the paper gap. Is set.

  As a result, when printing is performed on the paper P, the carriage 10 is closer to the platen 28 (hereinafter referred to as “N position”, see FIG. 1), and PG is relatively small. When printing is performed on the rigid recording material G, the carriage 10 is separated from the N position with respect to the platen 28 (hereinafter referred to as “++ position”, see FIG. 2). PG is set relatively large. In the following description, the platen gap set when the carriage 10 is in the N position may be referred to as “PG normal”, and the platen gap set when the carriage 10 is in the ++ position may be referred to as “PG ++”.

The rotation is controlled by driving means (not shown).

  On the other hand, the paper discharge driven rollers (21b, 22b) are disposed on the recording surface side of the paper P (that is, the front surface of the paper P) and are constituted by toothed rollers having a plurality of teeth on the outer periphery thereof. . The paper discharge frame 40 is attached so as to be freely rotatable in a state of projecting downward (that is, a recording material conveyance path).

It is configured so that it can be displaced. That is, the paper discharge frame 40 is in an approach state (a state corresponding to the contact state) positioned immediately above the recording material conveyance path so that the paper discharge driven rollers (21b, 22b) are positioned in the recording material conveyance path. ) And a retracted state (a state corresponding to the retracted state) in which the discharge driven rollers (21b, 22b) are retracted from the recording material conveyance path. ing. The sheet P is discharged toward the recording material stacker 50 by the discharge rollers (21, 22) having the above configuration.

  Next, a case where printing is performed on the rigid recording material G using the second conveyance path “maru 2” will be described with reference to FIG. In this case, by setting the recording material stacker 50 to the first position, the recording material placement surface 51 which is the upper surface of the recording material stacker 50 is made substantially horizontal and communicates to the bottom of the recording head 13. A supply / discharge path for the rigid recording material G is formed. Further, a position where the paper discharge driven rollers (21b, 22b) do not come into contact with the rigid recording material G with the paper discharge frame 40 retracted in conjunction with the recording material stacker 50 by a paper discharge frame displacement link mechanism 100 described later. To move. As a result, printing can be executed without contact between the paper discharge driven rollers (21b, 22b) and the rigid recording material G.

  Further, the conveyance driven roller 19b is separated from the conveyance driving roller 19a by a conveyance driven roller displacement link mechanism 200 described later. Thereby, the collision of the rigid recording material G with the conveyance driven roller 19b can be avoided, and the rigid recording material G can be pinched by the conveyance roller 19 and precisely fed.

  Further, by bringing the carriage 10 into the ++ position in conjunction with the recording material stacker 50 by a platen gap displacement link mechanism 300 described later, contact between the rigid recording material G and the recording head 13 can be avoided. The platen gap corresponding to the rigid recording material G can be adjusted.

As described above, the rigid recording material G is set on the recording material stacker 50 after the rigid recording material G can be conveyed linearly, and the recording head 13 is moved along the recording material placement surface 51. The rigid recording material G is inserted downward (that is, the recording portion), and after performing a cueing operation, printing is performed. Thus, printing can be performed in a state where contact between the rigid recording material G and the paper discharge driven rollers (21b, 22b) is avoided.
When the rigid recording material G is an optical recording medium such as a CD-R that cannot be directly conveyed, it is set in a dedicated tray (for example, a tray in which a concave portion into which the CD-R is fitted is formed). Recording is performed in the state where

<2. Configuration of Displacement Frame Displacement Link Mechanism>
Next, with reference to FIG. 3 to FIG. 8, the paper discharge frame displacement link mechanism 100 that displaces the paper discharge frame 40 between the contact state and the retracted state by displacing the recording material stacker 50 by position. explain.

  Here, FIG. 3 is a side view of the main part for explaining the paper discharge frame displacement link mechanism 100 according to the present embodiment, and FIG. 4 is a perspective view of the main part showing the same state as FIG. This shows a state where the stacker 50 is in the second position. FIG. 5 is a side view of a main part for explaining the paper discharge frame displacement link mechanism 100 according to the present embodiment. FIG. 6 is a perspective view of the main part showing the same state as FIG. A state where 50 is the first position is shown. FIG. 7 is a perspective view of the main part of the periphery of the guide cover 80 provided in the vicinity of the right end of the base end of the recording material stacker 50 as viewed from the upper downstream side, and FIG. 8 is viewed from a different angle from FIG. FIG. 4 is a perspective view of a main part around a guide cover 80. FIGS. 3 to 8 show the right side of the recording material stacker 50 when the printer 1 is viewed from the front side of the apparatus, and FIGS. 3 to 6 show the printer 1 from the right side. It shows the state.

  The recording material stacker 50 disposed on the front surface of the printer 1 feeds the rigid recording material G straight from the substantially horizontal recording material placement surface 51 to the bottom of the recording head 13 and performs recording. A first position (see FIGS. 5 and 6) capable of forming a straight supply / discharge path for discharging straight from the bottom of the head 13 onto the recording material mounting surface 51 and printing by being fed by the paper feeder 2 And a second position (see FIGS. 3 and 4) in which the sheet P to be discharged is stacked and is positioned lower than the first position and the recording material placing surface 51 is substantially inclined. It is configured to be displaceable so that it can be taken.

  The paper discharge frame displacement link mechanism 100 includes a release lever sub 55, a release lever 60, a rotation shaft 63, and a link frame 68. A pair of engaging shafts 52 projecting sideways are provided on both side surfaces on the upstream side (that is, the base end side) of the recording material stacker 50, and one of the engaging shafts 52 is a release lever sub. 55 is supported by a bearing portion (not shown) formed on the inner wall of 55. As a result, the recording material stacker 50 can swing about 90 degrees about the engaging shaft 52, and can be used in a substantially horizontal state that can be taken when the printer 1 is used, and in a substantially vertical storage state that can be taken when the printer 1 is not used (see FIG. (Not shown). By placing the recording material stacker 50 in the housed state, the placement area when the printer 1 is not in use can be reduced. The other end of the engagement shaft 52 is pivotally supported by an operating member 90 (see FIG. 9) described later.

  The release lever sub 55 that supports the engagement shaft 52 is configured to be movable in the vertical direction of the apparatus following the displacement between the first position and the second position of the recording material stacker 50. More specifically, as shown in FIG. 7, the release lever sub 55 is guided by the inner wall surface of the guide cover 80 disposed on the outer peripheral portion thereof, and extends in the vertical direction protruding toward the front of the apparatus. The sheet metal 83 made of a plate-like body is also guided by being fitted into a groove (not shown) extending in the vertical direction formed in the release lever sub 55 at a corresponding position of the sheet metal 83. With such a configuration, the release lever sub 55 is accurately positioned in the longitudinal direction of the apparatus and in the lateral direction of the apparatus when viewed from the front side of the apparatus, and reliably follows the movement of the recording material stacker 50 in the vertical direction. Be able to. Note that, as shown in FIG. 8, a moving path 80a of the engaging shaft 52 is formed on a wall portion 80b that constitutes a part of the guide cover 80 and is disposed between the recording material stacker 50 and the release lever sub 55. Is formed extending in the vertical direction of the apparatus.

  Returning to FIG. 3, in the release lever sub 55, a wall that forms the sliding groove 55 a is integrally formed. A boss portion 60a of the release lever 60 is fitted in the sliding groove 55a, and the release lever 60 is interlocked with the release lever sub 55 by sliding the boss portion 60a along the sliding groove 55a. It is rotated around the rotation shaft 63. Further, the release lever 60 is guided by the inner wall surface of the guide cover 80 described above, thereby restricting the release of the boss portion 60a from the sliding groove 55a.

  The rotation shaft 63 is formed in a D-shaped cross section, and is rotated in the same direction and in the same amount as the rotation of the release lever 60 by being fitted in the same bearing hole formed in the release lever 60. The other end of the rotation shaft 63 is fitted into the link frame 68 so that the rotation of the release lever 60 can be transmitted to the link frame 68. With such a configuration, the rotation of the release lever 60 is transmitted to the link frame 68 via the rotation shaft 63, and the link frame 68 can be rotated by the same amount in the same direction as the release lever 60. That is, the link frame 68 is configured to be unrotatable with respect to the release lever 60, so that the link frame 68 and the release lever 60 can be rotated in synchronization.

  In addition, a circular ring in which circular holes through which the rotation shaft 63 passes are formed at both ends of the rotation shaft 63, that is, in the vicinity of the engagement portion with the release lever 60 and the engagement portion with the link frame 68. 64 is disposed and is positioned while rotatably supporting the rotation shaft 63. Note that the rotation shaft 63 is not limited to the D-shaped cross section as in the present embodiment, and has a non-circular cross-sectional shape such as a triangular shape such as a triangular shape or a quadrangular shape. Can be used without limitation as long as the shape can be transmitted to the link frame 68 as it is.

  The link frame 68 is rotatably engaged with the paper discharge frame 40 via an engagement shaft 69 on the downstream side of the paper discharge frame 40. As a result, the link frame 68 is rotated about the rotation shaft 63, whereby the paper discharge frame 40 is displaced between the contact state and the retracted state.

  Further, the paper discharge frame 40 is constituted by a plate-like frame, and is urged toward an obliquely upstream side, that is, in a contact state by an urging spring 45 provided above the frame. Thereby, the upstream end portion (free end portion) of the paper discharge frame 40 can be reliably engaged with the engagement protrusion 71 described later, and the paper discharge frame 40 can be accurately positioned in the contact state. That is, when the paper discharge frame displacement link mechanism 100 operates, the paper discharge frame 40 can be in the retracted state.

  The side frame 70 is formed with a guide slope 73 that guides the displacement between the contact state and the retracted state of the paper discharge frame 40. The guide inclined surface 73 is substantially the locus that the engaging shaft 69 that is the engaging portion of the link frame 68 and the paper discharge frame 40 can take when the paper discharge frame 40 is displaced between the contact state and the retracted state. Are formed identically. The paper discharge frame 40 is integrally formed with a side J-shaped protrusion 41 that slides on the guide slope 73.

  With such a configuration, when the paper discharge frame 40 is displaced, the J-shaped protrusion 41 slides along the guide slope 73, so that the paper discharge frame 40 is maintained in the contacted posture. It can be displaced between the contact state and the retracted state. Accordingly, a height position at which the paper discharge driven rollers (21b, 22b) attached to the paper discharge frame 40 are surely retracted from the recording material conveyance path so as not to contact the rigid recording material G such as a CD-R. Can be moved to.

  In the present embodiment, the configuration in which the paper discharge frame 40 is in the retracted state while maintaining the substantially horizontal posture that is the contacted posture is described, but the retracted posture is not limited to this, The discharge driven rollers (21b, 22b) are not limited in any way as long as they are retracted from the recording material conveyance path and do not come into contact with the rigid recording material G. Therefore, for example, the upstream side of the paper discharge frame 40 can be retracted further upward than the engagement shaft 69.

  Further, the side frame 70 is formed with an engaging protrusion 71 for positioning in the contact state of the paper discharge frame 40 (see FIG. 5). The engaging protrusion 71 includes a protrusion 71 a that contacts the upstream end of the paper discharge frame 40 and a frame placement portion 71 b that supports the paper discharge frame 40 from below and determines the height position. Yes.

  With such a configuration, the upstream side end portion of the paper discharge frame 40 is engaged with the engagement protrusion 71, thereby positioning the upstream side. Since the paper discharge frame 40 is urged downward by the urging spring 45, the paper discharge frame 40 is securely and stably engaged with the engagement protrusion 71 for positioning, and is in a contact state. The posture can be accurately maintained. Further, as described above, the downstream side of the paper discharge frame 40 is engaged with the link frame 68 on the engagement shaft 69, and thereby the height position in the contact state and the retracted state is positioned.

  Here, the recording material stacker 50 is displaced from the second position (see FIGS. 3 and 4) to the first position (see FIGS. 5 and 6), so that the discharge frame 40 is moved from the contact state to the retracted state. The state displacement will be described.

  When the recording material stacker 50 takes the second position as shown in FIGS. 3 and 4, the discharge frame 40 causes the discharge driven rollers (21b, 22b) to abut the discharge drive rollers (21a, 22a). It is in the contact state. Incidentally, the posture of the recording material stacker 50 at the second position is such that the engaging shaft 52 is positioned at the lower end portion of the moving path 80a formed in the guide cover 80 as shown in FIG. The protruding portion (not shown) is maintained by being in contact with a leaf spring (not shown) provided in the recording material stacker 50 and on the upstream side of the engaging shaft 52. ing.

  From such a state, the recording material stacker 50 is once rotated about the engaging shaft 52 toward the apparatus main body (clockwise in FIG. 3) to be in a substantially vertical posture, and then lifted upward. Thereby, the release lever sub 55 is moved upward and the boss portion 60a of the release lever 60 slides from the position 55c toward the position 55d along the sliding groove 55a of the release lever sub 55. Accordingly, the release lever 60 rotates about the rotation shaft 63 (clockwise in FIG. 3).

  The rotation of the release lever 60 is transmitted to the link frame 68 via the rotation shaft 63 and rotates the link frame 68 by the same amount in the same direction. As a result, the paper discharge frame 40 engaged with the link frame 68 is lifted upward on the downstream side against the biasing force of the biasing spring 45. At this time, the J-shaped protrusion 41 on the upstream side of the paper discharge frame 40 is similarly lifted to the upper upstream side along the guide inclined surface 73, so that the paper discharge frame 40 is retracted while maintaining the contacted posture. It can be displaced to a state.

  Then, by rotating the recording material stacker 50 to the downstream side so that the recording material placement surface 51 is in a substantially horizontal posture, the recording material stacker 50 becomes the first position as shown in FIGS. The paper discharge frame 40 is in a retracted state in which the paper discharge driven rollers (21b, 22b) are separated from the paper discharge driving rollers (21a, 22a).

  As described above, when the recording material stacker 50 is in the first position, the paper discharge frame 40 can be in the retracted state, so that the paper discharge driven rollers (21b, 21b, 21) attached to the paper discharge frame 40 can be used. 22b) can be retracted from the recording material conveyance path and moved to a height position where it does not contact the rigid recording material G. Therefore, printing can be performed without contact between the paper discharge driven rollers (21b, 22b) and the rigid recording material G, so that a problem caused by the contact can be surely avoided.

  Next, the recording material stacker 50 is displaced from the first position (see FIGS. 5 and 6) to the second position (see FIGS. 3 and 4), so that the discharge frame 40 is moved from the retracted state to the contact state. Similarly, the state displacement will be described.

  First, the recording material stacker 50 is rotated toward the apparatus main body around the engaging shaft 52 (clockwise in FIG. 5) to have a substantially vertical posture, and then pushed downward. Accordingly, the release lever sub 55 is moved downward and the boss portion 60a of the release lever 60 slides from the position 55d toward the position 55c along the sliding groove 55a of the release lever sub 55. Accordingly, the release lever 60 rotates (counterclockwise in FIG. 5) about the rotation shaft 63 as a rotation center.

  The rotation of the release lever 60 is transmitted to the link frame 68 through the rotation shaft 63, and the link frame 68 is rotated by the same amount in the same direction. As a result, the paper discharge frame 40 engaged with the link frame 68 is pushed down on the upstream side. At this time, the J-shaped protrusion 41 on the upstream side of the paper discharge frame 40 is similarly pushed downward along the guide inclined surface 73 and the upstream end of the paper discharge frame 40 is engaged with the engagement protrusion 71. Together, they are positioned in the contact state. As described above, since the paper discharge frame 40 is urged toward the contact state by the urging spring 45, it can be reliably engaged with the engagement protrusion 71, so that the contact state is accurately set. Can be positioned.

  Then, by rotating the recording material stacker 50 to the downstream side, as shown in FIGS. 3 and 4, the recording material stacker 50 becomes the second position, and the paper discharge frame 40 has the paper discharge driven rollers (21b, 22b). Is brought into contact with the paper discharge drive rollers (21a, 22a).

  As described above, when the recording material stacker 50 is in the second position, the paper discharge frame 40 can be brought into a contact state, so that the paper P that is fed from the paper feeding device 2 and printed. Can be reliably discharged, and the discharged paper P can be reliably stacked on the recording material stacker 50.

  Further, as shown in FIG. 8, pinions 85 are rotatably attached to engaging shafts 52 provided on both sides of the recording material stacker 50, and a rack 86 is provided at a corresponding position on the apparatus main body side. Is formed. With this configuration, the position displacement of the recording material stacker 50 can be performed while maintaining the parallel state of the recording material stacker 50. That is, when the recording material stacker 50 is displaced between the first position and the second position, the pinion 85 moves while meshing with the rack 86, so that the left and right ends of the recording material stacker 50 are synchronized. It can be moved by the same amount. Therefore, for example, the recording material stacker 50 is not parallel and difficult to move.

  As described above, the printer 1 displaces the recording material stacker 50 to displace the discharge frame 40 holding the discharge driven rollers (21b, 22b) between the contact state and the retracted state. A paper frame displacement link mechanism 100 is provided. Therefore, by setting the recording material stacker 50 to the second position, it is possible to perform printing on the paper P using the first transport path “Maru 1” with the paper discharge frame 40 in a contact state, and to be recorded By setting the material stacker 50 to the first position, it is possible to perform printing on the rigid recording material G using the second transport path “maru 2” with the paper discharge frame 40 in the retracted state. In this way, printing can be reliably performed on many types of recording materials.

  Further, when the second transport path “Maru 2” is used and printing is performed on, for example, a CD-R, the paper discharge frame 40 is retracted in conjunction with the displacement of the recording material stacker 50. Therefore, printing can be performed without the discharge driven rollers (21b, 22b) coming into contact with the CD-R or the like.

  Further, since the user can displace the paper discharge frame 40 to the corresponding state only by displacing the position of the recording material stacker 50, the operation is extremely easy, and there is no possibility of causing an operation error. The apparatus configuration can be simplified.

<3. Configuration of Conveyance Driven Roller Displacement Link Mechanism and Platen Gap Displacement Link Mechanism>
Next, the conveyance driven roller displacement link mechanism and the platen gap displacement link mechanism will be described.
Here, FIG. 9 is a perspective view of a main part for explaining the transport driven roller displacement link mechanism 200 and the platen gap displacement link mechanism 300 in the present embodiment, and FIG. 10 is a diagram for explaining the transport driven roller displacement link mechanism 200. FIG. 11 is a perspective view of a principal part for explaining the platen gap displacement link mechanism 300. FIGS. 12 to 14 are diagrams for explaining the operations of the transport driven roller displacement link mechanism 200 and the platen gap displacement link mechanism 300. It is a principal part side view to provide.

  When focusing on the position of the recording material stacker 50, FIGS. 9, 10, and 12 show the case of the second position, and FIGS. 11, 13, and 14 show the case of the first position. It is. Further, the transport driven roller displacement link mechanism 200 and the platen gap displacement link mechanism 300 described here are the opposite sides of the paper discharge frame displacement link mechanism 100 described above, and the printer 1 when viewed from the front side of the apparatus. The recording material stacker 50 is arranged on the left side of the apparatus. 9 to 14 are views of the printer 1 as viewed from the left side.

  As shown in FIG. 9, the printer 1 operates a control lever 32 as an operation unit to swing the transport driven roller holder 18 to separate the transport driven roller 19b from the transport drive roller 19a. The distance between the recording head 13 mounted on the carriage 10 supported by the carriage guide shaft 12 and the platen 28 by displacing the carriage guide shaft 12 in conjunction with the positions of the mechanism 200 and the recording material stacker 50. A platen gap displacement link mechanism 300 for adjusting the platen gap (PG) is provided.

  First, the conveyance driven roller displacement link mechanism 200 will be described with reference to FIGS. 9 and 10. Here, FIG. 9 is a perspective view of the main part of the printer 1 and shows the conveyance driven roller displacement link mechanism 200 and the platen gap displacement link mechanism 300. FIG. 10 shows the printer 1 viewed from an angle different from FIG. It is a principal part perspective view, shows the conveyance driven roller displacement link mechanism 200, and the platen gap displacement link mechanism 300 is omitted.

  The transport driven roller displacement link mechanism 200 includes an operation lever 32, a third transmission component 33, and a fourth transmission component 34 provided on the left side of the front of the apparatus (left side of the recording material stacker 50) as an operation unit. .

  The operation lever 32 is configured to be swingable about 90 degrees about the swing shaft 32a. A rod-shaped third transmission component 33 is attached to the operation lever 32 via an engagement portion 33a formed in the main body portion 32c on the upstream side. The fourth transmission component 34 is attached to the third transmission component 33 via the engaging portion 33b, and the cam rotation shaft 31 is fixedly attached to the fourth transmission component 34. Yes. The operation lever 32 is weakly urged toward the upstream side (device main body side) by an urging member (for example, a rubber material) (not shown), thereby restricting unnecessary swinging. Yes.

  With such a configuration, the conveyance driven roller holder 18 is rocked against the urging force by rotating the cam rotation shaft 31 via the third transmission component 33 and the fourth transmission component 34 by operating the operation lever 32. The transport driven roller 19b can be moved away from the transport drive roller 19a.

  That is, when the operation portion 32b of the operation lever 32 is rotated upstream (on the rear side of the apparatus), the conveying driven roller holder 18 is brought into contact with the urging means described above to bring the conveying driven roller 19b into the conveying driving roller 19a. (See FIG. 1). Further, when the operation portion 32b of the operation lever 32 is rotated to the downstream side (the front side of the apparatus), the conveyance driven roller holder 18 is oscillated against the urging force so as to be separated from the conveyance driven roller. 19b can be separated from the conveyance drive roller 19a (see FIG. 2).

  The main body 32c of the operation lever 32 is disposed in a space formed inside an operating member 90 described later. With such a configuration, when the recording material stacker 50 is in the second position, the operation of the operation lever 32 is restricted, so that the operation of the conveyance driven roller displacement link mechanism 200 is regulated and the conveyance driven roller holder 18 is moved. It is maintained in contact. The operation lever 32 can be operated only when the operating member 90 moves upward in accordance with the recording material stacker 50 being in the first position.

Next, the platen gap displacement link mechanism 300 will be described with reference to FIGS. 9 and 11. Here, FIG. 11 is a perspective view of the main part of the printer 1, showing the platen gap displacement link mechanism 300, with the conveyance driven roller displacement link mechanism 200 and a part of the guide cover 96 omitted.
The platen gap displacement link mechanism 300 includes an actuating member 90 that supports an engaging shaft 52 that protrudes laterally from the recording material stacker 50, a first transmission component 91, a second transmission component 92, and a rotating body 93. Have.

  The actuating member 90 has a first side portion 90a on the recording material stacker 50 side and a second side portion 90b on the outer side, which are provided in parallel to each other, and protrudes upward when viewed from the downstream side. Are arranged in a letter shape. The engaging shaft 52 is pivotally supported on the first side portion 90a, and can be displaced in the vertical direction of the apparatus in conjunction with (following) the recording material stacker 50. Yes. Further, the path of the engagement shaft 52 is disposed on the wall portion 96b of the guide cover 96 which is disposed between the recording material stacker 50 and the operation member 90, and a part of which is omitted in FIG. 96a is formed extending in the vertical direction of the apparatus. The operation member 90 is restricted from unnecessary movement in the apparatus front-rear direction and the apparatus left-right direction along the inner surface of the guide cover 96.

  Further, a first transmission component 91 having a “V” shape in a side view is attached to the second side portion 90b of the operating member 90 via the engaging portion 91a so as to be swingable about the swinging fulcrum 91b. . The swing fulcrum 91b is pivotally supported by the guide cover 96 so as to be swingable. The first transmission component 91 is attached with a linear second transmission component 92 via an engagement portion 92a. Further, the second transmission component 92 has an engagement portion 93a having a predetermined play. A rotating body 93 is attached through the vias. The rotating body 93 is configured to support the carriage guide shaft 12 at a position deviated from the rotation center of the rotating body 93 via the eccentric bush portion 94.

  With such a configuration, the rotating member 93 is rotated by the displacement of the recording material stacker 50 via the operating member 90, the first transmission component 91, and the second transmission component 92. The carriage guide shaft 12 supported at a position deviated from the center can be displaced in the vertical direction of the apparatus. Thereby, PG can be adjusted.

  That is, when the recording material stacker 50 is in the second position, the carriage guide shaft 12 is displaced vertically downward (that is, the direction approaching the platen 28), and the carriage 10 is set to the N position, thereby causing the platen gap. Is adjusted to PG normal, and when the recording material stacker is in the first position, the carriage guide shaft 12 is displaced vertically upward (that is, the direction away from the platen 28) to move the carriage 10 to the ++ position. Thus, the platen gap is adjusted to PG ++.

  Thus, by adjusting the platen gap according to the recording material, the distance (paper gap) between the recording surface of the recording material and the recording head 13 can be adjusted as appropriate regardless of the thickness of the recording material. Therefore, good print quality can be obtained. Further, when the recording material is a rigid recording material G such as a thick CD-R, the contact between the rigid recording material G and the recording head 13 can be avoided by setting to PG ++. .

  A sensor (not shown) is provided in the vicinity of the rotator 93 so that the position of the carriage 10 can be recognized by detecting the rotation of the rotator 93.

  Here, operations of the transport driven roller displacement link mechanism 200 and the platen gap displacement link mechanism 300 will be described with reference to FIGS. 12 to 14. 12 to 14 show the transport driven roller displacement link mechanism 200, the platen gap displacement link mechanism 300, and the recording material stacker 50. FIG. For convenience of explanation, the recording material stacker 50 will be described based on the operation, and the recording material stacker 50 is displaced from the second position (see FIG. 12) to the first position (see FIGS. 13 and 14). The case will be described, and in the overall state of the printer 1, FIGS.

  As shown in FIG. 12, when the recording material stacker 50 is in the second position, the carriage guide shaft 12 is maintained so that the carriage 10 is in the N position, and the transport driven roller holder 18 is in contact. Maintained (see FIG. 1). As described above, the paper discharge frame 40 is in a contact state.

  The operation of the operation lever 32 is restricted by the operating member 90. That is, the actuating member 90 restricts the main body portion 32c of the operation lever 32 from above, and thereby the rotation of the operation lever 32 is restricted. Accordingly, the transport driven roller displacement link mechanism 200 cannot be operated by operating the operation lever 32. Therefore, when the recording material stacker 50 is in the second position, the transport driven roller holder 18 is transported by the transport driven roller. The contact state in which 19b is brought into contact with the transport driving roller 19a is maintained.

  From such a state, the recording material stacker 50 is once rotated about the engaging shaft 52 toward the apparatus main body (counterclockwise direction in FIG. 12) to have a substantially vertical posture and then lifted upward. Accordingly, the operating member 90 is also driven and lifted upward, and the first transmission component 91 swings upstream (counterclockwise in FIG. 12) about the swing fulcrum 91b. In conjunction with the movement of the first transmission component 91, the rotating body 93 rotates upstream (in the counterclockwise direction in FIG. 12) via the second transmission component 92, and deviates from the rotation center of the rotating body 93. The carriage guide shaft 12 pivotally supported at the position via the eccentric bush 94 is displaced upward (that is, the direction in which the carriage 10 is separated from the platen 28), and the carriage 10 is displaced to the ++ position. Then, by rotating the recording material stacker 50 to the downstream side, the state shown in FIG. 13 can be obtained.

  Thus, by displacing the recording material stacker 50 from the second position to the first position, the carriage 10 can be displaced from the N position to the ++ position, and the platen gap can be switched from PG normal to PG ++. That is, when the recording material stacker 50 is in the first position, the platen gap can be set to PG ++. As described above, when the recording material stacker 50 is in the first position, the paper discharge frame 40 is in the retracted state.

  As shown in FIG. 11, the first position of the recording material stacker 50 is such that the engaging shaft 52 is positioned at the uppermost part of the moving path 96 a formed in the guide cover 96 and the rotating body 93 is counteracted by the torsion spring 97. It is maintained by energizing clockwise. The substantially horizontal posture of the recording material stacker 50 at the first position is such that the locking portion 96c integrally formed with the guide cover 96 is engaged with the locking portion 50c integrally formed with the recording material stacker 50. Are held together.

  Further, as shown in FIG. 13, the operating member 32 is lifted in conjunction with the recording material stacker 50, so that the restriction of the operation lever 32 is released. That is, the operation lever 32 can be operated only when the recording material stacker 50 is in the first position.

Next, the case where the operation driven lever 32 is operated to operate the transport driven roller displacement link mechanism 200 will be described.
As shown in FIG. 13, in the state where the recording material stacker 50 is in the first position, the operation lever 32 is swung around the swing shaft 32a toward the downstream side of the apparatus (clockwise in FIG. 13). . Thereby, the 4th transmission component 34 rotates centering on the cam rotation shaft 31 via the 3rd transmission component 33, and it can be in the state shown in FIG. By the rotation of the cam rotation shaft 31, the cam member 36 comes into contact with the cam follower portion 18b as described above, and the conveyance driven roller holder 18 swings against the urging force and is displaced to the separated state. In this way, the transport driven roller 19b can be separated from the transport drive roller 19a (see FIG. 2).

  Further, as shown in FIG. 14, the recording material stacker 50 is in the first position and the operation lever 32 is swung to the front side of the apparatus (that is, the conveyance driven roller holder 18 is in the separated state). When the recording material stacker 50 is displaced toward the second position, the state shown in FIG. 12 is entered at once, and the operating lever 32 is forcibly swung toward the apparatus main body as the operating member 90 is lowered. The conveyance driven roller holder 18 is displaced to the contact state via the conveyance driven roller displacement link mechanism 200, and the carriage 10 is moved to the N position via the platen gap displacement link mechanism 300 to set the platen gap to PG normal. .

  As described above, the printer 1 is configured to be able to displace the discharge frame 40, the platen gap, and the transport driven roller holder 18 in conjunction with the position of the recording material stacker 50.

  That is, when the recording material stacker 50 is in the second position, the platen gap is set to PG normal by bringing the paper discharge frame 40 into a contact state and positioning the carriage 10 in the N position as shown in FIG. Further, the conveyance driven roller holder 18 is brought into a contact state.

  When the recording material stacker 50 is in the first position, the platen gap is set to PG ++ by placing the paper discharge frame 40 in the retracted state and positioning the carriage 10 in the ++ position as shown in FIG. The transport driven roller holder 18 can be in a separated state.

  Therefore, the user can set the paper discharge frame 40, the platen gap, and the transport driven roller holder 18 to the optimum state according to the purpose of printing by operating the recording material stacker 50 and the operation lever 32, and the operability is improved. Is extremely high.

  Next, another embodiment of the platen gap displacement link mechanism 300 will be described with reference to FIG. In addition, about the member which performs the same function, the same code | symbol as FIG. 11 is attached | subjected and description is abbreviate | omitted.

  In this embodiment, as shown in the figure, the shapes of the operating member 90, the first transmission member 91, and the second transmission member 92 are different from those of the previous embodiment (see FIG. 11). By setting it as such a shape, adjustment with the member which is not illustrated becomes smooth, and the platen gap displacement link mechanism 300 can be operated more efficiently.
