It is characterized by comprising second discharge means for winding and discharging around a conveying belt, and guide means for guiding the recording sheet to the first discharge means or the second discharge means.
排紙部300には、下方排紙ローラ301と下方拍車302からなる下方排紙ローラ対352と、上方排紙ローラ311と上方拍車312からなる上方排紙ローラ対354が配設されている。下方拍車302は下方排紙ローラ301に対し、上方拍車312は上方排紙ローラ311に対し、それぞれ従動回転可能にばね付勢力により押圧されている。下方排紙ローラ対352は、そのニップ(記録シート挟持部)が記録ヘッドHにより記録された記録シートPを搬送ベルト203を介してベルト従動ローラ202に巻き付けるように搬送する巻き付け搬送位置となるように配置されている。また、上方排紙ローラ対354は、そのニップが記録領域における搬送ベルト203とほぼ一直線をなす延長線上に搬送経路を形成する非巻き付け搬送位置となるように配置されている。下方排紙ローラ301は支持部材305に軸受306を介して軸支され、上方排紙ローラ311は軸受306を介して支持部材315に軸支されている。下方拍車302は拍車ホルダ304に軸支され、上方拍車312は拍車ホルダ314に軸支されている。そして、下方の拍車ホルダ304は下方の支持部材305に対し、上方の拍車ホルダ314は上方の支持部材315に対し、それぞれビス等で固定(締結)されている。 The paper discharge unit 300 is provided with a lower paper discharge roller pair 352 composed of a lower paper discharge roller 301 and a lower spur 302, and an upper paper discharge roller pair 354 composed of an upper paper discharge roller 311 and an upper spur 312. The lower spur 302 is pressed against the lower discharge roller 301 and the upper spur 312 is pressed against the upper discharge roller 311 by a spring biasing force so as to be driven to rotate. The lower discharge roller pair 352 has a nip (recording sheet clamping portion) at a winding conveyance position where the recording sheet P recorded by the recording head H is conveyed around the belt driven roller 202 via the conveyance belt 203. Is arranged. Further, the upper discharge roller pair 354 is arranged so that the nip thereof is a non-wrapping conveyance position that forms a conveyance path on an extension line that is substantially in line with the conveyance belt 203 in the recording region. The lower paper discharge roller 301 is pivotally supported by the support member 305 via the bearing 306, and the upper paper discharge roller 311 is pivotally supported by the support member 315 via the bearing 306. The lower spur 302 is pivotally supported by a spur holder 304, and the upper spur 312 is pivotally supported by a spur holder 314. The lower spur holder 304 is fixed (fastened) to the lower support member 305 and the upper spur holder 314 to the upper support member 315 with screws or the like.
図4(a)は排紙部300における記録シートPのコックリング発生状態を示す斜視図である。図4(b)は排紙部において記録シートが搬送ベルト203を介してベルト従動ローラ202に巻き付いて搬送される状態を示す縦断面図である。図4(c)は記録シートが搬送ベルトを介してベルト従動ローラに巻き付いている状態を示す斜視図である。案内手段350Aを構成する押さえ拍車303は、図3(a)の巻き付け搬送位置と図3(b)の非巻き付け搬送位置の2つの位置に切り換え移動するように、制御手段95により制御される。巻き付け搬送位置は、記録ヘッドHによる記録が終了し搬送ベルト203に吸着された状態で搬送されてきた記録シートPを、搬送ベルト203を介してベルト従動ローラ202に巻き付けるように搬送する位置である。これに対し、非巻き付け位置は、搬送ベルト203の記録領域における搬送面とほぼ一直線上の位置に向けて記録シートPを搬送する位置である。ここで、記録シートPが普通紙や薄紙等の剛性の低い記録シートの場合、記録ヘッドHにより記録されると、時間経過とともに図4(a)に示すような搬送方向と交差する方向のコックリング(波打ち)が発生する。 FIG. 4A is a perspective view illustrating a state where cockling of the recording sheet P occurs in the paper discharge unit 300. FIG. 4B is a longitudinal cross-sectional view showing a state in which the recording sheet is wound around the belt driven roller 202 via the conveyance belt 203 and conveyed in the paper discharge unit. FIG. 4C is a perspective view showing a state in which the recording sheet is wound around the belt driven roller via the conveyance belt. The control spur 303 that constitutes the guide means 350A is controlled by the control means 95 so as to switch and move between two positions, a winding conveyance position in FIG. 3A and a non-wrapping conveyance position in FIG. 3B. The winding conveyance position is a position where the recording sheet P conveyed after being recorded by the recording head H and adsorbed to the conveyance belt 203 is conveyed so as to be wound around the belt driven roller 202 via the conveyance belt 203. . On the other hand, the non-winding position is a position where the recording sheet P is conveyed toward a position substantially in line with the conveyance surface in the recording area of the conveyance belt 203. Here, in the case where the recording sheet P is a recording sheet having low rigidity such as plain paper or thin paper, when recording is performed by the recording head H, the cock in the direction intersecting with the conveying direction as shown in FIG. A ring (waving) occurs.
図4において、記録された記録シートPに発生するコックリングを搬送ベルト203の吸着力で抑制している間に、押さえ拍車303により記録シートPを搬送ベルト203を介して巻き付き領域Lの範囲でベルト従動ローラ202に巻き付かせる。記録シートPは搬送ベルト203を介して従動ローラ202に巻き付くことで湾曲し、記録面に垂直な方向の記録シートPの剛性が高まる。それによって、記録面と垂直な方向に成長しようとするコックリングを抑制することができる。また、記録シートの先端部Paが巻き付き領域Lを通過した後にコックリングが成長し始めた場合でも、搬送ベルト203を介してベルト従動ローラ202に巻き付いた巻き付き領域Lで、コックリングが記録シートの搬送下流側に成長していくのを抑制することができる。 In FIG. 4, while the cockling generated on the recorded recording sheet P is suppressed by the suction force of the conveying belt 203, the recording sheet P is moved by the holding spur 303 within the range of the winding region L via the conveying belt 203. The belt is wound around the belt driven roller 202. The recording sheet P is bent by being wound around the driven roller 202 via the conveyance belt 203, and the rigidity of the recording sheet P in the direction perpendicular to the recording surface is increased. Thereby, cockling that tries to grow in a direction perpendicular to the recording surface can be suppressed. Even when the cockling begins to grow after the leading end portion Pa of the recording sheet has passed through the winding area L, the cockling is in the winding area L that is wound around the belt driven roller 202 via the conveying belt 203. It is possible to suppress growth on the downstream side of the conveyance.
ユーザが記録シートの種類として普通紙等の剛性の低い記録シートを指定(選択)した場合は、下方給紙部101から給送された剛性の低い記録シートPが搬送ベルト203を介してベルト駆動ローラ201とピンチローラ208のニップ部に到達する。ここで挟持された記録シートPは、給電ローラ210で帯電された搬送ベルト203に押し付けられることで、搬送ベルト203の表面に静電吸着される。そして、搬送ベルト203に吸着されて搬送される記録シートPに対して、記録ヘッドHによる記録が行われる(ステップS605)。記録が終了した記録シートPは、搬送ベルト203に吸着された状態で押さえ拍車303により上面を押さえられ、搬送ベルト203を介してベルト従動ローラ202に巻き付くような経路で搬送される。こうして搬送される記録シートPは、その先端部Paが剥離部材309に達すると剥離部材309により搬送ベルト203から離間させられ、下方の拍車ホルダ304および剥離部材309にガイドされながら下方排紙ローラ301と下方拍車302のニップ部に到達する。そして、記録シートPは、記録ヘッドHによる最終行の記録が終了した後に、下方排紙ローラ301および下方拍車302により装置本体外に排出される(ステップS606)。 When the user designates (selects) a low-stiffness recording sheet such as plain paper as the type of recording sheet, the low-stiffness recording sheet P fed from the lower paper feed unit 101 is belt-driven via the transport belt 203. It reaches the nip portion between the roller 201 and the pinch roller 208. The recording sheet P sandwiched here is electrostatically attracted to the surface of the conveyance belt 203 by being pressed against the conveyance belt 203 charged by the power supply roller 210. Then, recording by the recording head H is performed on the recording sheet P that is attracted and conveyed by the conveying belt 203 (step S605). The recording sheet P for which recording has been completed is conveyed by a path in which the upper surface is pressed by the pressing spur 303 while being attracted to the conveying belt 203 and wound around the belt driven roller 202 via the conveying belt 203. When the leading end Pa reaches the peeling member 309, the recording sheet P thus conveyed is separated from the conveying belt 203 by the peeling member 309, and is guided by the lower spur holder 304 and the peeling member 309, and the lower discharge roller 301. And reaches the nip portion of the lower spur 302. Then, after the recording of the last line by the recording head H is completed, the recording sheet P is discharged out of the apparatus main body by the lower discharge roller 301 and the lower spur 302 (step S606).
以上のように、記録装置には、記録シートPの種類を指定する記録シート指定手段(プリンタドライバ501等)を備え、記録前に指定された記録シートの種類に応じて、案内手段350Aの巻き付け位置と非巻き付け位置との切り換えを行うように構成されている。したがって、記録シートPの種類が剛性の低い普通紙等である場合は、記録後にコックリングが発生しても、記録シートPを搬送ベルト203を介してベルト従動ローラ202に巻き付くように搬送することによりコックリングの成長を抑制することができる。一方、記録シートPの種類が剛性の高い特殊紙等である場合には、記録シートPを一直線上に搬送することで安定した状態で精度良く搬送することができる。 As described above, the recording apparatus includes the recording sheet designating unit (such as the printer driver 501) that designates the type of the recording sheet P, and the guide unit 350A is wound according to the type of the recording sheet designated before recording. It is configured to switch between a position and a non-winding position. Therefore, when the type of the recording sheet P is plain paper with low rigidity, even if cockling occurs after recording, the recording sheet P is conveyed so as to be wound around the belt driven roller 202 via the conveying belt 203. Thus, the growth of cockling can be suppressed. On the other hand, when the type of the recording sheet P is high-stiffness special paper or the like, the recording sheet P can be conveyed in a stable state with high accuracy by being conveyed in a straight line.
支持部材325は、ベルト従動ローラ202の第2のローラ部202bと嵌合する嵌合部325aを有し、第2のローラ部202b(ベルト従動ローラ202)の軸心を中心に回動可能な可動支持部材となっている。支持部材325の回動動作は、支持部材325のカム当接部325bに当接するカム326によって行われる。カム308は回動可能であり、カム308の駆動は排紙部駆動モータ517(図5)によって行われる。つまり、本実施形態では、可動拍車ホルダ324に軸支された拍車322および押さえ拍車323と、可動支持部材325に軸支された排紙ローラ321は、可動支持部材325および可動拍車ホルダ324と共に、一体となってベルト従動ローラ202の軸心を中心として回動可能に構成されている。 The support member 325 has a fitting portion 325a that fits with the second roller portion 202b of the belt driven roller 202, and is rotatable about the axis of the second roller portion 202b (belt driven roller 202). It is a movable support member. The rotation of the support member 325 is performed by a cam 326 that contacts the cam contact portion 325b of the support member 325. The cam 308 is rotatable, and the cam 308 is driven by a paper discharge unit drive motor 517 (FIG. 5). That is, in this embodiment, the spur 322 and the pressing spur 323 that are pivotally supported by the movable spur holder 324, and the paper discharge roller 321 that is pivotally supported by the movable support member 325, together with the movable support member 325 and the movable spur holder 324, The belt driven roller 202 is integrally configured to be rotatable about the axis.
排紙ローラ321、拍車322および押さえ拍車323は、図8(a)および図9(a)に示す巻き付け搬送位置と図8(b)および図9(b)に示す非巻き付け搬送位置との2つの位置に移動可能(切り換え可能)である。巻き付け搬送位置は、記録ヘッドHにより記録され、搬送ベルト203に吸着されて搬送されてきた記録シートPを、搬送ベルト203を介してベルト従動ローラ202に巻き付けるように搬送する位置である。一方、非巻き付け搬送位置は、記録領域における搬送ベルト203の搬送面の延長線上のほぼ一直線上に搬送する位置である。こうして、本実施形態では、押さえ拍車323からなる回転体と拍車ホルダ324からなる支持体とにより、巻き付け位置と非巻き付け位置とに切り換え移動可能な案内手段350Bが構成されている。また、排紙部300全体も巻き付け位置と非巻き付け位置との間で切り換え移動可能である。したがって、案内手段350Bは、巻き付け位置と非巻き付け位置とに切り換え移動可能な排紙部300と一体に移動可能である。この場合、支持部材325に取り付けられた剥離部材309も排紙部300と共に移動し、記録シートを搬送ベルト203から離間させるとともに、離間した記録シートの下面をガイドする案内部材として機能する。本実施形態の上記以外の構成は、前述の第1の実施形態と同様である。 The paper discharge roller 321, the spur 322, and the pressing spur 323 are two of the winding conveyance position shown in FIGS. 8A and 9A and the non-wrapping conveyance position shown in FIGS. 8B and 9B. It can be moved to one position (switchable). The winding conveyance position is a position where the recording sheet P recorded by the recording head H and attracted to the conveyance belt 203 and conveyed is conveyed so as to be wound around the belt driven roller 202 via the conveyance belt 203. On the other hand, the non-wrapping conveyance position is a position where the sheet is conveyed substantially on a straight line on the extended line of the conveyance surface of the conveyance belt 203 in the recording area. In this way, in this embodiment, the guide body 350B that can be switched between the winding position and the non-winding position is configured by the rotating body including the holding spur 323 and the support body including the spur holder 324. Further, the entire paper discharge unit 300 can also be switched between a winding position and a non-winding position. Therefore, the guide unit 350B can move integrally with the paper discharge unit 300 that can be switched between a winding position and a non-winding position. In this case, the peeling member 309 attached to the support member 325 also moves together with the paper discharge unit 300 to separate the recording sheet from the conveyance belt 203 and to function as a guide member that guides the lower surface of the separated recording sheet. Other configurations of the present embodiment are the same as those of the first embodiment described above.
