加圧ローラユニット８は、記録媒体を搬送する搬送ローラ９ごとに対をなすように配設されるものである。搬送ローラ９に向けて記録媒体を加圧しながら、ローラ１４が従動回転する。つまり、記録媒体は、下面は搬送ローラ９と接し、上面は加圧ローラユニット８のローラ１４と接する。また、この加圧ローラユニット８は、プリンタ１の基台１３に固定して取り付けられる。   The pressure roller unit 8 is disposed so as to form a pair for each conveyance roller 9 that conveys a recording medium. The roller 14 is driven and rotated while pressurizing the recording medium toward the conveying roller 9. That is, the lower surface of the recording medium is in contact with the conveying roller 9, and the upper surface is in contact with the roller 14 of the pressure roller unit 8. The pressure roller unit 8 is fixedly attached to the base 13 of the printer 1.

加圧ローラユニット８は、ローラ１４と、ローラ１４の回転軸を回動可能に支持するローラ軸支部１５、ローラ軸支部１５と着脱可能なローラ支持部１６を備える。ローラ軸支部１５には軸孔１７が設けられ、ローラ１４の両端に設けられた略円柱状の凸部が軸孔１７に挿入され、ローラ１４が回動可能に軸支される。   The pressure roller unit 8 includes a roller 14, a roller shaft support portion 15 that rotatably supports a rotation shaft of the roller 14, and a roller support portion 16 that can be attached to and detached from the roller shaft support portion 15. The roller shaft support portion 15 is provided with a shaft hole 17, and substantially cylindrical convex portions provided at both ends of the roller 14 are inserted into the shaft hole 17, so that the roller 14 is rotatably supported.

ローラ支持部１６は、第１当接部１８と第２当接部１９を備えている。ローラ支持部１６の一端から伸び出た突起部に、バネを掛ける凹部２０を備える。また、ローラ支持部１６の両サイドの中央からややローラ１４寄りに、軸受２１を夫々のサイドに備える。基台１３は、基台１３に加圧ローラユニット８を固定するため、不図示ではあるが、第１当接部１８または第２当接部１９のどちらかに当接する第３当接部を備えるスライド板、バネを掛ける凹部２０に掛けられるバネの他端を掛ける部材、軸受２１に嵌る軸が備わっている。そしてこれらによって、基台１３に遥動可能に加圧ローラユニット８を取り付けることができる。すなわち、軸と軸受２１によって、加圧ローラユニット８を回動可能に支持する。そして、バネを掛ける凹部２０にバネの一端を掛け、バネの他端をバネの他端を掛ける部材に掛けることでローラ１４を一定の方向に加圧する。そして、スライド板をスライドさせ、第３当接部を第１当接部１８に当接させるか第２当接部１９に当接させるかによって、ローラ１４を搬送ローラ９に接触させて加圧状態にするか、あるいは開放状態にするかの選択をする。また、加圧ローラユニット８を搬送ローラ９へ加圧及び開放する機構は従来技術と同様の構成が可能である。   The roller support portion 16 includes a first contact portion 18 and a second contact portion 19. A concave portion 20 is provided on a protrusion extending from one end of the roller support portion 16 to hang a spring. Also, bearings 21 are provided on the respective sides, slightly closer to the roller 14 from the center of both sides of the roller support portion 16. Although the base 13 fixes the pressure roller unit 8 to the base 13, a third abutting portion that abuts on either the first abutting portion 18 or the second abutting portion 19 is not shown. A slide plate provided, a member for hanging the other end of the spring hung on the recess 20 for hanging the spring, and a shaft fitted to the bearing 21 are provided. Thus, the pressure roller unit 8 can be attached to the base 13 so as to be slidable. That is, the pressure roller unit 8 is rotatably supported by the shaft and the bearing 21. Then, one end of the spring is hung on the recess 20 where the spring is hung, and the other end of the spring is hung on a member hung on the other end of the spring, thereby pressing the roller 14 in a certain direction. Then, the slide plate is slid and the roller 14 is brought into contact with the conveying roller 9 and pressed depending on whether the third contact portion is brought into contact with the first contact portion 18 or the second contact portion 19. Select whether to open or open. The mechanism for pressing and releasing the pressure roller unit 8 to the transport roller 9 can have the same configuration as that of the prior art.

Thus, an upper surface plate 42 is provided on the upper surface side. The first side wall 33, the second side wall 36, the first inner wall 34, and the second inner wall 35 are each provided with a concave system stop groove 23, which fits with a system stop protrusion 22 described later. A first slide plate stop hole 38 is provided at the end of the portion sandwiched between the first side wall 33 and the first inner wall 34 to stop a first stop portion 30 of the first slide plate 26 described later. Similarly, a second slide plate system stop hole 39 is provided at the end of the portion sandwiched between the second side wall 36 and the second inner wall 35 to stop the second system stop portion 32 of the second slide plate 28 described later. . A central system stop hole 25 is provided between the first inner wall 34 and the second inner wall 35 of the upper surface plate 42, and a central system stop protrusion 24 described later fits therein. The central stop hole 25 is an elliptical hole that is provided in the central portion of the first side wall 33 and the second side wall 36 and is long in the side wall direction.

ローラ軸支部１５には、第１スライド板２６、第２スライド板２８、中央スライド板２７が備わっている。第１スライド板２６は、第１スライド板側壁２９を有するＬ字型状の板の突起であり、先端部に第１系止部３０を有する。第２スライド板２８は、第２スライド板側壁３１を有するＬ字型状の板の突起であり、先端部に第２系止部３２を有する。中央スライド板２７は板状の突起で、略先端部に中央系止突起２４を有する。中央系止突起２４の先端周部にはテーパー部３７を有する。第１スライド板側壁２９及び第２スライド板側壁３１の先端部はテーパー部３８を有する。   The roller shaft support portion 15 includes a first slide plate 26, a second slide plate 28, and a central slide plate 27. The first slide plate 26 is a protrusion of an L-shaped plate having a first slide plate side wall 29 and has a first system stop 30 at the tip. The second slide plate 28 is a protrusion of an L-shaped plate having a second slide plate side wall 31 and has a second system stop 32 at the tip. The central slide plate 27 is a plate-like protrusion, and has a central system stop protrusion 24 at a substantially distal end portion. A taper portion 37 is provided on the tip peripheral portion of the central stop protrusion 24. The tip portions of the first slide plate side wall 29 and the second slide plate side wall 31 have a tapered portion 38.

第１系止部３０の先端周部はテーパー部４０を有する。第２系止部３２の先端周部はテーパー部４１を有する。第１スライド板２６、中央スライド板２７および第２スライド板２８の間、及びローラ軸支部１５の両サイドには系止突起２２が備わり、夫々対応する系止溝２３に嵌合する。系止突起２２は４つあるが、そのうち３つは図上では部品の影で見えない。   The tip peripheral portion of the first system stop 30 has a tapered portion 40. The tip periphery of the second system stop 32 has a taper 41. System stop projections 22 are provided between the first slide plate 26, the central slide plate 27, and the second slide plate 28, and on both sides of the roller shaft support portion 15, and are fitted in the corresponding system stop grooves 23, respectively. There are four system stop protrusions 22, but three of them are not visible in the figure by the shadow of the part.

また、第１スライド板２６、第２スライド板２８、中央スライド板２７は夫々突起状に形成されているので、突起の根元に対して先端が撓む構造となっている。   Further, since the first slide plate 26, the second slide plate 28, and the central slide plate 27 are each formed in a protrusion shape, the tip is bent with respect to the root of the protrusion.

次に、ローラ軸支部１５とローラ支持部１６の着脱について説明する。   Next, attachment / detachment of the roller shaft support portion 15 and the roller support portion 16 will be described.

系止突起２２は挿抜方向に長く、さらに系止溝２３に嵌合する。さらに、系止溝２３は上側及び下側には壁があるがキャリッジ４の走査方向には壁が無い。これにより、キャリッジ４の走査方向には外れやすくなるが、記録媒体の搬送方向に垂直方向、すなわち搬送ローラ９に加圧する方向及びそれに抗する方向には移動が規制されるので外れにくい。   The system stop protrusion 22 is long in the insertion / removal direction, and further fits into the system stop groove 23. Further, the system stop groove 23 has walls on the upper side and the lower side, but has no wall in the scanning direction of the carriage 4. Accordingly, the carriage 4 is easily detached in the scanning direction, but the movement is restricted in the direction perpendicular to the recording medium conveyance direction, that is, the direction in which the conveyance roller 9 is pressed and the direction against it.

さらに、第１スライド板２６、第２スライド板２８、中央スライド板２７は夫々上面４１と接する。第１スライド板側壁２９の外側面と第１側壁３３の内側面および第２スライド板側壁３１の外側面と第２側壁３６の内側面は、微小間隔で隔てられ隣接している。これにより、搬送ローラ９に加圧する方向に対して、移動が規制される。そして、キャリッジ４の走査方向に対しては、微小に移動することができる。   Further, the first slide plate 26, the second slide plate 28, and the central slide plate 27 are in contact with the upper surface 41, respectively. The outer side surface of the first slide plate side wall 29 and the inner side surface of the first side wall 33 and the outer side surface of the second slide plate side wall 31 and the inner side surface of the second side wall 36 are adjacent to each other with a small gap therebetween. Thereby, the movement is restricted with respect to the direction in which the conveying roller 9 is pressed. The carriage 4 can move minutely with respect to the scanning direction.

第１系止部３０の下面側と第１スライド板系止孔３８の側面が接し、第２系止部３２の下面側と第２スライド板系止孔３９の側面が接している。これにより、搬送ローラ９に加圧する方向に抗する方向に対して、移動が規制される。   The lower surface side of the first system stop 30 and the side surface of the first slide plate system stop hole 38 are in contact, and the lower surface side of the second system stop portion 32 and the side surface of the second slide plate system stop hole 39 are in contact. Thereby, the movement is restricted with respect to the direction against the direction in which the conveying roller 9 is pressed.

第１系止部３０と第１スライド板系止孔３８のキャリッジ４の走査方向には隙間が設けられている。第２系止部３２と第２スライド板系止孔３９のキャリッジ４の走査方向には隙間が設けられている。第１系止部３０と第２系止部３２はキャリッジ４の走査方向には隙間があるので、移動しやすい。また、第１系止部３０にはテーパー部４０、第２系止部３２にはテーパー部４１があるので、第１系止部３０、第２系止部３２が動き始めると動きやすい。しかし、搬送ローラ９に加圧する方向に対して、移動が規制される。   A gap is provided in the scanning direction of the carriage 4 between the first system stop 30 and the first slide plate system stop hole 38. A gap is provided in the scanning direction of the carriage 4 between the second system stopper 32 and the second slide plate system hole 39. The first system stop 30 and the second system stop 32 are easy to move because there is a gap in the scanning direction of the carriage 4. Further, since the first system stop 30 has the tapered portion 40 and the second system stop 32 has the taper 41, it is easy to move when the first system stop 30 and the second system stop 32 start to move. However, the movement is restricted with respect to the direction in which the conveying roller 9 is pressed.

中央系止孔２５はキャリッジ４の走査方向に長く、中央系止突起２４は円柱状なので、キャリッジ４の走査方向に移動しやすい。中央スライド板２７は撓み、さらに中央系止突起２４はテーパー部３７を有するので、中央系止突起２４が動き始めると動きやすい。また、中央系止突起２４が中央系止孔２５に系止されることで、ローラ軸支部１５をローラ支持部１６に系止することができる。中央スライド板２７が撓まない限り、中央系止突起２４が中央系止孔２５から抜けることは無い。   Since the central system stop hole 25 is long in the scanning direction of the carriage 4 and the central system stop protrusion 24 is cylindrical, it is easy to move in the scanning direction of the carriage 4. Since the central slide plate 27 is bent and the central system stop protrusion 24 has a tapered portion 37, it is easy to move when the center system stop protrusion 24 starts to move. Further, the central shaft stop projection 24 is stopped by the central stop hole 25, whereby the roller shaft support portion 15 can be stopped by the roller support portion 16. As long as the central slide plate 27 is not bent, the central system stop projection 24 will not come out of the central system stop hole 25.

このような構成によって、基台１３に固定された加圧ローラユニット８が開放状態の場合に、ローラ軸支部１５をローラ支持部１６の上面板４２に沿ってスライド板２６，２７，２８をスライドさせながら、系止突起２３を系止溝２３に嵌合させながら、系止部３０、３２をスライド板系止孔３８，３９へ挿入しながら、系止凸部２４を系止孔２５へ挿入しながら、装着することが容易にできる。すなわち、インクジェットプリンタ１の正面から、加圧ローラユニット８を開放状態にして、記録媒体の搬送方向すなわち、インクジェットプリンタ１の前後方向にローラ軸支部１５をローラ支持部１６に対して挿抜が容易にできる。   With such a configuration, when the pressure roller unit 8 fixed to the base 13 is in an open state, the slide shafts 26, 27, and 28 are slid along the upper surface plate 42 of the roller support portion 16. While inserting the system stop projection 23 into the system stop groove 23, the system stop protrusions 24 are inserted into the system stop holes 25 while the system stop portions 30 and 32 are inserted into the slide plate system stop holes 38 and 39. However, it can be easily mounted. That is, the pressure roller unit 8 is opened from the front of the ink jet printer 1, and the roller shaft support portion 15 can be easily inserted into and removed from the roller support portion 16 in the recording medium conveyance direction, that is, the front and rear direction of the ink jet printer 1. it can.

ローラ軸支部１５とローラ支持部１６を接続すると、ローラ支持部１６の先端部の全面がローラ軸支部１５に接する。よって、加圧ローラユニット８を搬送ローラ９に加圧する方向及びそれに抗する方向に対しての外力に対しては更に外れ難い構成となる。   When the roller shaft support portion 15 and the roller support portion 16 are connected, the entire front end portion of the roller support portion 16 is in contact with the roller shaft support portion 15. Therefore, it becomes a structure which is hard to remove | deviate with respect to the external force with respect to the direction which pressurizes the pressure roller unit 8 to the conveyance roller 9, and the direction which opposes it.

また、ローラ軸支部１５を、系止突起２３の長手方向に向かって引き抜く場合は、中央系止突起２４が中央系止孔２５から外れるように中央スライド板２７が撓み、ローラ支持部１６から外すことができる。テーパー部３７があるので、引き抜いたときに、中央スライド板２７が撓み、中央系止突起２４が中央系止孔２５に引っかからずに滑るように抜ける。   Further, when the roller shaft support portion 15 is pulled out in the longitudinal direction of the system stop projection 23, the center slide plate 27 is bent so that the center system stop projection 24 is removed from the center system stop hole 25, and is removed from the roller support portion 16. be able to. Since the taper portion 37 is present, the central slide plate 27 bends when pulled out, and the central system stop protrusion 24 slips out without being caught by the central system stop hole 25.

ローラ軸支部１５は、ローラ支持部１６との挿抜が容易におこなえるので、ローラ１４の回転不良や汚れたときに、バネ等をはずさず面倒な作業無しに、交換が可能となる。よって機器のメンテナンスの作業効率が向上する。   The roller shaft support portion 15 can be easily inserted into and removed from the roller support portion 16, so that when the roller 14 is poorly rotated or dirty, the roller shaft support portion 15 can be replaced without removing the spring and the like without troublesome work. Therefore, the work efficiency of equipment maintenance is improved.

また、ジャムが発生すると、記録媒体にキャリッジ４が衝突し、その影響で記録媒体が加圧ローラユニット８に絡みつく場合がある。このとき、加圧ローラユニット８へは、キャリッジ４の走査方向からの外力が加わる。この外力によって、ローラ軸支部１５がローラ支持部１６から外れることで、衝撃の緩和と、部品の破損の防止ができる。また、記録媒体が絡みつく部品が少なくなるので、容易に記録媒体を取り除くことができ、さらに、容易に外れたローラ軸支部１５を装着することができる。   Further, when a jam occurs, the carriage 4 may collide with the recording medium, and the recording medium may be entangled with the pressure roller unit 8 due to the impact. At this time, an external force from the scanning direction of the carriage 4 is applied to the pressure roller unit 8. By this external force, the roller shaft support portion 15 is disengaged from the roller support portion 16, so that the impact can be reduced and the parts can be prevented from being damaged. Further, since the number of parts with which the recording medium is entangled is reduced, the recording medium can be easily removed, and the roller shaft support portion 15 that has been easily detached can be mounted.

ローラ軸支部１５へキャリッジ４の走査方向からの外力が加わった場合、第１スライド板２６あるいは第２スライド板２８が撓み、さらに中央スライド板２７が撓み、中央系止突起２４が中央系止孔２５から外れ、系止突起２３が系止溝２３から外れ、ローラ軸支部１５がローラ支持部１６から抜ける。   When an external force from the scanning direction of the carriage 4 is applied to the roller support 15, the first slide plate 26 or the second slide plate 28 is bent, the center slide plate 27 is further bent, and the center system stop projection 24 is the center system stop hole. 25, the system stop projection 23 is removed from the system stop groove 23, and the roller shaft support portion 15 comes out of the roller support portion 16.

ローラ軸支部１５は、搬送ローラ９方向への外力には外れにくく、キャリッジ４の走査方向からの外力によって外れやすい構成となっているので、ジャムなど異常搬送が生じたときに、ローラ軸支部１５はローラ支持部１６から容易に外れる。部品の交換も容易なので機器のメンテナンスの作業効率が向上する。   The roller shaft support portion 15 is configured not to be easily released by an external force in the direction of the transport roller 9 and is easily released by an external force from the scanning direction of the carriage 4. Therefore, when an abnormal transport such as a jam occurs, the roller shaft support portion 15 Is easily removed from the roller support 16. Since parts can be easily replaced, the efficiency of equipment maintenance is improved.

図５は、加圧ローラユニット８と補強ユニット４３の配置図である。ジャムが発生し、記録媒体が加圧ローラユニット８に当たると、加圧ローラユニット８はローラ支持部１６からローラ軸支部１５が外れ、破損をぼうしできる。しかし、加圧ローラユニット８に記録媒体が当たるということは、少なからずや加圧ローラユニット８に負荷がかかってしまう。そこで、加圧ローラユニット８が配置されている間に、補助ユニット４３を設けることで、加圧ローラユニット８にかかる負荷を減少させることができ、更なる破損の防止が可能である。   FIG. 5 is a layout diagram of the pressure roller unit 8 and the reinforcing unit 43. When a jam occurs and the recording medium hits the pressure roller unit 8, the pressure roller unit 8 can remove the roller shaft support portion 15 from the roller support portion 16 and can be damaged. However, the fact that the recording medium hits the pressure roller unit 8 causes a considerable load on the pressure roller unit 8. Therefore, by providing the auxiliary unit 43 while the pressure roller unit 8 is disposed, the load applied to the pressure roller unit 8 can be reduced, and further damage can be prevented.

図６は、加圧ローラユニットの別の形態を示した斜視図である。ローラ軸支部１５の側面に補強部４５を設ける。補強部４５は、他の部分に比べ肉厚とする。別の形態としては、内部あるいは表面に金属板を配置し、他の部分に比べ強度を上げる。これにより、補強された部分の強度を上げることで、走査方向に加わった外力に対して加圧ローラユニット８が分離するときに、強度の弱いところから撓みなじめるので分離しやすくなる。そのため、破損防止効果が向上する。   FIG. 6 is a perspective view showing another form of the pressure roller unit. A reinforcing portion 45 is provided on the side surface of the roller shaft support portion 15. The reinforcement part 45 is made thicker than other parts. As another form, a metal plate is arrange | positioned inside or on the surface, and intensity | strength is raised compared with another part. Thus, by increasing the strength of the reinforced portion, when the pressure roller unit 8 is separated from an external force applied in the scanning direction, the pressure roller unit 8 can be easily bent because it is bent from a weak strength. Therefore, the damage prevention effect is improved.

ローラ支持部１６の側面に補強部４６を設ける。補強部４６は、他の部分に比べ肉厚とする。別の形態としては、内部あるいは表面に金属板を配置し、他の部分に比べ強度を上げる。これにより、補強された部分の強度を上げることで、走査方向に加わった外力に対して加圧ローラユニット８が分離するときに、強度の弱いところから撓みなじめるので分離しやすくなる。そのため、破損防止効果が向上する。   A reinforcing portion 46 is provided on the side surface of the roller support portion 16. The reinforcing part 46 is made thicker than other parts. As another form, a metal plate is arrange | positioned inside or on the surface, and intensity | strength is raised compared with another part. Thus, by increasing the strength of the reinforced portion, when the pressure roller unit 8 is separated from an external force applied in the scanning direction, the pressure roller unit 8 can be easily bent because it is bent from a weak strength. Therefore, the damage prevention effect is improved.

ローラ支持部１６にテーパー部４４を設ける。テーパー部４４は、ローラ支持部１６とローラ軸支部１５との接する部分の一部に設けられる。テーパー部４４は、通常の加圧時には外れやすくしないため、加圧方向に対しては設けずに、走査方向に設ける。ローラ支持部１６とローラ軸支部１５との間に隙間を空けることで、走査方向にかかる外力に対して他の部分に比べ分離しやすくする。そのため、破損防止効果が向上する。   A tapered portion 44 is provided on the roller support portion 16. The tapered portion 44 is provided at a part of a portion where the roller support portion 16 and the roller shaft support portion 15 are in contact with each other. The taper portion 44 is not provided in the pressurizing direction but is provided in the scanning direction because it does not easily come off during normal pressurization. By providing a gap between the roller support portion 16 and the roller shaft support portion 15, it is easier to separate the external force applied in the scanning direction than other portions. Therefore, the damage prevention effect is improved.
