Description

【0001】
【発明の属する技術分野】
本発明は、プリンタなどの記録装置に関し、特に、液体成分を吐出して記録を行う記録装置に関する。
【0002】
【従来の技術】
従来、液体成分を吐出して記録を行う記録装置は、液体成分の吸収とそれに続く記録媒体の膨張により発生するコックリングと呼称される皺または波打ち状の変形の影響を排除して安定な記録を行うために、記録媒体保持部に凸部形状部を備え、かつ、記録媒体を記録媒体保持部側へ付勢する付勢拍車を備えて安定化させるコックリング制御の提案がなさなれていた(例えば、特許文献1参照)。
【0003】
図3を参照すると、コックリング制御を行うために構成された搬送部と記録媒体保持部と排紙部が示されている。
【0004】
搬送部は、搬送ローラ9とピンチローラ10などを備えており、搬送部に送られた記録シートは、搬送ローラ9とピンチローラ10の間のニップ部に送られる。ピンチローラ10は、搬送ローラ9に押圧されており、搬送ローラ9の回転に従動回転して記録シートの搬送力を生み出している。
【0005】
記録媒体保持部は、プラテン11などを備えており、その表面には、記録シートの搬送方向と平行に、2種類の凸部形状部が複数本形成されている。第1の凸部形状部であるリブ11aは、後述する排紙ローラ28と拍車30の上流側に配置されている。また、後述する付勢拍車62の上流側には、2つの第2のリブ11bが対峙して配置されている。
【0006】
リブ11aとリブ11bはそれぞれ、記録ヘッドの吐出口と平行な平坦面部11a−1、11b−1、および、搬送方向上流側へプラテン11に向かって傾斜する傾斜面部11a−2、11b−2を有している。そして、リブ11aの平坦面部11a−1の方がリブ11bの平坦面部11b−1より高く、かつ、記録シートの搬送方向に長く形成され、また、リブ11bの傾斜面部11b−2の方がリブ11aの傾斜面部11a−2より緩やかに形成されている。
【0007】
排紙部は、排紙ローラ28と、拍車ホルダにバネ軸29を介して挿入されて、バネ軸29の付勢力により排紙ローラ28に押圧され、排紙ローラ28の回転に従動回転し、記録シートに点接触して記録シートの搬送力を発生させる拍車30を備えている。また、2つの排紙ローラ28(拍車30)の間に、拍車ホルダにバネ軸29を介して挿入され、記録シートを記録ヘッドから遠ざける方向(すなわちプラテン11の方向)に付勢する付勢拍車62を備えている。
【0008】
図4は、リブ11a上に沿った、搬送部と記録媒体保持部と排紙部の断面図である。ピンチローラ10は、搬送方向下流側にオフセットした位置で搬送ローラ9に付勢されるため、記録シートPの先端は、斜め下方に向かって搬送されることになる。搬送ローラ9およびピンチローラ10の間に搬送された記録シートPは、搬送ローラ9の回転により、プラテン11上を記録開始位置まで所定量搬送される。そして、記録ヘッド19の吐出口19aからの液体吐出により、所定の画像情報に基づいた記録が行われる。
【0009】
コックリング制御が必要な普通紙などでは、吐出された液体の吸収によって記録媒体が膨張する。このような膨張の効果を上記の構成によって記録媒体全体にわたって吸収するので、記録媒体が記録ヘッドをこするなどの問題を回避できる。
【0010】
【特許文献1】
特開2000−158644号公報
【0011】
【発明が解決しようとする課題】
しかしながら、上記の従来の記録装置では、記録媒体に記録を開始する前の状態から、記録媒体に予め微小な波打ち状態を発生させる。そのため、コックリングの発生しにくい記録媒体にも微小な波打ちを発生させ、この記録媒体への記録に波打ち上のムラが発生しやすくなってしまうという欠点があった。
【0012】
本発明の目的は、コックリング制御が必要な記録媒体にのみコックリング制御を実行し、コックリング制御が不要な記録媒体にはコックリング制御を実行しないようにすることにより、画像劣化の発生しない記録装置を提供することにある。
【0013】
【課題を解決するための手段】
上記目的を達成するために、本発明は、従来の付勢拍車を記録媒体上に作用する位置または作用しない位置に選択的に配置することを行う。
【0014】
このために、所定の幅と深さの溝が設けられた、付勢拍車を保持する保持部と、この幅以上の直径を有し、軸に平行な平面によって一部が切り取られた円柱の軸棒を設け、軸棒を溝の中で軸を中心に回転させる。前記の平面が保持部と向き合う場合に、付勢拍車は記録媒体に作用する位置に配置されことになる。
【0015】
そして、付勢拍車の選択的な配置は、記録媒体の種類に応じて実行される。この種類は、インクジェット用記録ヘッドを含む記録ヘッドから吐出される記録剤の液体成分によってコックリングと呼称される皺または波打ち状の変形が発生しやすい記録媒体と、コックリングが発生しにくい記録媒体に分類する。付勢拍車は、コックリングの発生しやすい記録媒体の場合には、記録媒体に作用する位置に配置され、コックリングの発生しにくい記録媒体の場合には、記録媒体に作用しない位置に配置されるようにする。コックリングの発生しやすい記録媒体の少なくとも1つは普通紙であり、コックリングの発生しにくい記録媒体の少なくとも1つは光沢紙である。
【0016】
さらに、使用者から記録媒体の種類に関する入力情報を受け付け、この入力情報に基づいて、付勢拍車の配置の切替えを行ってもよい。
【0017】
さらに、記録媒体の種類の判別を行う紙種判別センサを設け、この判別に基づき、付勢拍車の配置の切替えを行ってもよい。
【0018】
【発明の実施の形態】
以下、本発明の実施の形態について、図面を参照して説明する。
【0019】
図1を参照すると、本発明の一実施形態の記録装置の排紙部の上面図が示されている。なお、搬送部と記録媒体保持部は、従来技術を示す図3と同一なので省略する。
【0020】
排紙部は、排紙ローラ(不図示)と、拍車ホルダ54にバネ軸29を介して挿入されて、バネ軸29の付勢力により排紙ローラに押圧され、排紙ローラの回転に従動回転し記録シートに点接触して記録シートの搬送力を発生させる拍車30を備えている。また、排紙ローラと拍車30の組の間に、拍車ホルダ61にバネ軸29を介して挿入され、記録シートを記録ヘッドから遠ざける方向に付勢する付勢拍車62を備えている。拍車ホルダ54は、拍車ステイ55に固定されている。拍車ホルダ61は、一端が、回転中心軸61a部が拍車ステイ55の嵌合溝55a部に挿入され、回転中心軸61a部を中心に回動自在に拍車ステイ55に装着され、他端が、拍車ステイ55に装着された弾性部材57で拍車ステイ55に付勢されている。
【0021】
拍車ホルダ61には、不図示の側板に、回動自在に装着されたDカット軸58が作用するが、この点が本発明の特徴である。
【0022】
次に、図2を参照して、記録シートがコックリングしやすい普通紙P’の場合と、コックリングしにくい光沢紙P”の場合の、本発明の排紙部の動作を説明する。
【0023】
まず、普通紙P’への記録の指示が使用者から実施されると、不図示の駆動源の動作および不図示の伝達系の作用により、拍車ホルダの下部の溝に配置されたDカット軸58は図2(a)に示した状態になる。この状態において普通紙P’が搬送部に搬送されると、普通紙P’は付勢拍車62の作用とリブ11aおよび11bにより、図2(c)に示したような波打ち状態となり、特許文献1で述べられているのと同様なコックリング制御が実施される。
【0024】
次に、光沢紙P”への記録の指示が使用者から実施されると、不図示の駆動源の動作および不図示の伝達系の作用により、Dカット軸58は、図2(a)の状態から中心軸58aを中心にして180°回転した、図2(b)に示した状態になる。この状態において光沢紙P”が搬送部に搬送されると、光沢紙P”には付勢拍車62が作用しない状態になっているため、図2(d)に示したように、光沢紙P”は平滑な状態で維持され、インクジェット用記録ヘッドを含む記録ヘッドの吐出口から光沢紙P”の被記録面までの距離が均一な状態で、記録ヘッドによる光沢紙P”への記録が実施されることになる。
【0025】
本実施形態では、付勢拍車62を記録シートに作用させてコックリング制御を実施する記録シートを普通紙P’、付勢拍車62を記録シートに作用させないで、コックリング制御を実施しない記録シートを光沢紙P”で説明したが、それぞれの場合をそれぞれの記録シートに限定している訳ではない。例えば、表1に示したように、コックリング制御を実施する記録シートは、普通紙およびHR101のような高品位専用紙、コックリング制御を実施しない記録シートは、PR101のような写真専用紙、GP301のような光沢紙、HG201のような光沢フィルム、はがき、封筒、OHPフィルムというように設定してもよい。
【0026】

【0027】
本実施形態では、記録する記録シートの選択をプリンタドライバー等で使用者が指定して実施する場合について説明したが、不図示の紙種判別センサを記録装置の給紙部と搬送部の間に設け、紙種判別センサの検知結果によって、付勢拍車62の記録シートに作用する位置と作用しない位置への切換え動作を実施しても同様の効果を得ることができる。
【0028】
【発明の効果】
以上説明したように、本発明によれば、コックリング制御の必要な記録シートにのみコックリング制御を実施し、コックリング制御の不必要な記録シートにはコックリング制御を実施ないようにするため、コックリング制御が不要にもかかわらず、画一的にコックリング制御をしてしまうことによる画像劣化が発生しないという効果がある。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a printing apparatus such as a printer, and more particularly to a printing apparatus that performs printing by discharging a liquid component.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, a recording apparatus that performs recording by ejecting a liquid component has achieved stable recording by eliminating the influence of wrinkle or wavy deformation called cockling caused by absorption of a liquid component and subsequent expansion of a recording medium. In order to perform the above, a proposal has been made for cockling control in which the recording medium holding unit is provided with a convex-shaped portion, and is provided with an urging spur for urging the recording medium toward the recording medium holding unit, thereby stabilizing the recording medium. (For example, see Patent Document 1).
[0003]
FIG. 3 shows a transport unit, a recording medium holding unit, and a paper discharge unit configured to perform cockling control.
[0004]
The transport unit includes a transport roller 9 and a pinch roller 10. The recording sheet sent to the transport unit is sent to a nip between the transport roller 9 and the pinch roller 10. The pinch roller 10 is pressed by the transport roller 9 and rotates following the rotation of the transport roller 9 to generate a recording sheet transport force.
[0005]
The recording medium holding unit includes a platen 11 and the like, and a plurality of two types of convex portions are formed on the surface thereof in parallel with the recording sheet conveyance direction. The rib 11a, which is the first convex-shaped portion, is disposed upstream of a paper discharge roller 28 and a spur 30, which will be described later. Further, two second ribs 11b are arranged to face each other on the upstream side of the urging spur 62 described later.
[0006]
The ribs 11a and 11b respectively have flat surface portions 11a-1 and 11b-1 parallel to the ejection openings of the recording head and inclined surface portions 11a-2 and 11b-2 inclined toward the platen 11 upstream in the transport direction. Have. The flat surface portion 11a-1 of the rib 11a is higher than the flat surface portion 11b-1 of the rib 11b and is formed longer in the transport direction of the recording sheet, and the inclined surface portion 11b-2 of the rib 11b is larger than the rib 11b-1. 11a is formed more gently than the inclined surface portion 11a-2.
[0007]
The paper discharge unit is inserted into the paper discharge roller 28 and the spur holder via a spring shaft 29, is pressed by the paper discharge roller 28 by the urging force of the spring shaft 29, and rotates following the rotation of the paper discharge roller 28, A spur 30 is provided for generating a conveying force of the recording sheet by making point contact with the recording sheet. An urging spur inserted between the two paper discharge rollers 28 (spur 30) via a spring shaft 29 in a spur holder to urge the recording sheet away from the recording head (ie, in the direction of the platen 11). 62 are provided.
[0008]
FIG. 4 is a cross-sectional view of the transport unit, the recording medium holding unit, and the paper discharge unit along the rib 11a. Since the pinch roller 10 is urged by the transport roller 9 at a position offset to the downstream side in the transport direction, the leading end of the recording sheet P is transported diagonally downward. The recording sheet P conveyed between the conveying roller 9 and the pinch roller 10 is conveyed on the platen 11 by a predetermined amount to a recording start position by the rotation of the conveying roller 9. Then, recording based on predetermined image information is performed by discharging liquid from the discharge ports 19a of the recording head 19.
[0009]
On plain paper or the like that requires cockling control, the recording medium expands due to the absorption of the discharged liquid. Since the effect of such expansion is absorbed over the entire recording medium by the above configuration, problems such as the recording medium rubbing the recording head can be avoided.
[0010]
[Patent Document 1]
JP 2000-158644 A
[Problems to be solved by the invention]
However, in the above-described conventional recording apparatus, a minute undulating state is generated in advance on the recording medium from a state before recording on the recording medium is started. For this reason, there is a disadvantage that a minute undulation is generated even on a recording medium in which cockling is unlikely to occur, and unevenness in the undulation is likely to occur in recording on this recording medium.
[0012]
An object of the present invention is to prevent cockling control only on a recording medium that requires cockling control and not execute cockling control on a recording medium that does not require cockling control, thereby preventing image degradation. A recording device is provided.
[0013]
[Means for Solving the Problems]
In order to achieve the above object, the present invention selectively arranges a conventional urging spur on a recording medium at a position where it works or a position where it does not work.
[0014]
For this purpose, a holding portion for holding the biasing spur, provided with a groove of a predetermined width and depth, and a cylinder having a diameter equal to or greater than this width and partially cut by a plane parallel to the axis. A shaft is provided and the shaft is rotated about the shaft in the groove. When the plane faces the holding portion, the biasing spur is located at a position acting on the recording medium.
[0015]
Then, the selective arrangement of the urging spurs is executed according to the type of the recording medium. This type is a recording medium in which wrinkle or wavy deformation called cockling is easily generated by a liquid component of a recording agent ejected from a recording head including an ink jet recording head, and a recording medium in which cockling is hardly generated. Classify into. The urging spur is arranged at a position where it acts on the recording medium in the case of a recording medium in which cockling is likely to occur, and is arranged in a position where it does not act on the recording medium in the case of a recording medium in which cockling is unlikely to occur. So that At least one of the recording media in which cockling easily occurs is plain paper, and at least one of the recording media in which cockling does not easily occur is glossy paper.
[0016]
Further, input information regarding the type of the recording medium may be received from the user, and the arrangement of the urging spurs may be switched based on the input information.
[0017]
Further, a paper type discrimination sensor for discriminating the type of the recording medium may be provided, and the arrangement of the biasing spurs may be switched based on the discrimination.
[0018]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0019]
Referring to FIG. 1, there is shown a top view of a paper discharge unit of a recording apparatus according to an embodiment of the present invention. Note that the transport unit and the recording medium holding unit are the same as in FIG.
[0020]
The paper discharge unit is inserted into a spur holder 54 via a spring shaft 29 and is pressed by the paper discharge roller by the urging force of the spring shaft 29, and is driven by the rotation of the paper discharge roller. Further, a spur 30 for generating a conveying force of the recording sheet by point contact with the recording sheet is provided. Further, between the pair of the discharge roller and the spur 30, there is provided an urging spur 62 which is inserted into the spur holder 61 via the spring shaft 29 and urges the recording sheet away from the recording head. The spur holder 54 is fixed to a spur stay 55. One end of the spur holder 61 has a rotation center shaft 61a inserted into the fitting groove 55a of the spur stay 55, and is attached to the spur stay 55 so as to be rotatable about the rotation center shaft 61a. The spur stay 55 is urged by an elastic member 57 attached to the spur stay 55.
[0021]
The spur holder 61 has a D-cut shaft 58 rotatably mounted on a side plate (not shown), which is a feature of the present invention.
[0022]
Next, with reference to FIG. 2, the operation of the paper discharge unit of the present invention in the case where the recording sheet is plain paper P 'which is easily cockled and in the case where the recording sheet is glossy paper P "which is not easily cockled will be described.
[0023]
First, when a user instructs recording on the plain paper P ', the operation of the drive source (not shown) and the action of the transmission system (not shown) cause the D-cut shaft arranged in the lower groove of the spur holder to move. 58 is in the state shown in FIG. When the plain paper P 'is conveyed to the conveyance section in this state, the plain paper P' is wavy as shown in FIG. 2C by the action of the urging spur 62 and the ribs 11a and 11b. Cockling control similar to that described in 1 is performed.
[0024]
Next, when the user instructs the recording on the glossy paper P ″, the D-cut shaft 58 is moved by the operation of the drive source (not shown) and the operation of the transmission system (not shown) as shown in FIG. 2B, the state is rotated by 180 ° about the central axis 58a from this state, and when the glossy paper P ″ is conveyed to the conveyance section in this state, the glossy paper P ″ is urged. Since the spur 62 does not act, as shown in FIG. 2D, the glossy paper P ″ is maintained in a smooth state, and the glossy paper P is discharged from the discharge port of the recording head including the inkjet recording head. The recording on the glossy paper P by the recording head is performed in a state where the distance to the recording surface is uniform.
[0025]
In the present embodiment, the recording sheet on which the urging spur 62 acts on the recording sheet to perform the cockling control is the plain paper P ′, and the recording sheet on which the urging spur 62 does not act on the recording sheet and the cockling control is not performed is performed. Is described with glossy paper P ″, but each case is not limited to each recording sheet. For example, as shown in Table 1, recording sheets for which cockling control is performed include plain paper and High-quality exclusive paper such as HR101, a recording sheet for which cockling control is not performed include photographic exclusive paper such as PR101, glossy paper such as GP301, glossy film such as HG201, postcard, envelope, and OHP film. May be set.
[0026]
[Table 1]
Figure 2004098601
[0027]
In the present embodiment, a case has been described in which the user selects a recording sheet to be recorded by a printer driver or the like and executes the selection. However, a paper type discrimination sensor (not shown) is provided between the paper feeding unit and the conveyance unit of the recording apparatus. The same effect can be obtained even if the switching operation between the position where the urging spur 62 acts on the recording sheet and the position where it does not act is performed based on the detection result of the paper type discrimination sensor.
[0028]
【The invention's effect】
As described above, according to the present invention, cockling control is performed only on recording sheets that require cockling control, and cockling control is not performed on recording sheets that do not require cockling control. In addition, even though cockling control is unnecessary, there is an effect that image deterioration due to uniform cockling control does not occur.
