Description

本開示は、シート搬送装置に関する。 The present disclosure relates to a sheet transfer device.

排出トレイにストッパが設けられて、排出トレイへ排出される被記録媒体が排出トレイから脱落するのを、ストッパによって抑制可能に構成された画像形成装置が知られている（例えば、特許文献１参照。）。特許文献１に記載のストッパは、排出トレイに対して回動可能に取り付けられ、ストッパを使用する場合にはストッパを立てることができ、ストッパを使用しない場合にはストッパを倒すことができるように構成されている。 An image forming apparatus is known in which a stopper is provided on the discharge tray so that the recording medium discharged to the discharge tray can be suppressed from falling off from the discharge tray (see, for example, Patent Document 1). .). The stopper described in Patent Document 1 is rotatably attached to the discharge tray so that the stopper can be erected when the stopper is used and can be tilted when the stopper is not used. It is configured.

特開２０１２−１８３１０６号公報Japanese Unexamined Patent Publication No. 2012-183106

ところで、上記特許文献１に記載の画像形成装置は、画像形成装置の上部に画像読取装置を備えた複合機として構成されている。被記録媒体が排出される排出トレイは、画像読取装置の下方となる位置に設けられている。複合機の正面には開口が設けられ、排出トレイへと排出された被記録媒体は、開口を通じて装置の外部へ取り出し可能となっている。 By the way, the image forming apparatus described in Patent Document 1 is configured as a multifunction device provided with an image reading apparatus above the image forming apparatus. The discharge tray from which the recording medium is discharged is provided at a position below the image reading device. An opening is provided in the front of the multifunction device, and the recording medium discharged to the discharge tray can be taken out of the device through the opening.

しかし、上述のような開口から被記録媒体を取り出す際、ストッパが立ててあると、ストッパが障害物となって、その分だけ実質的な開口が狭くなるので、被記録媒体を取り出しにくくなる。特に、装置の高さ方向（上下方向）寸法を小型化したい場合には、上述のような開口の高さ方向寸法も小さめに設定される可能性があり、そのような場合には、ストッパが邪魔になりやすく、シートを取り出しにくくなる。 However, when the recording medium is taken out from the opening as described above, if the stopper is set up, the stopper becomes an obstacle and the opening is substantially narrowed by that amount, so that it becomes difficult to take out the recording medium. In particular, when it is desired to reduce the height direction (vertical direction) dimension of the device, the height direction dimension of the opening as described above may be set smaller, and in such a case, the stopper is used. It is easy to get in the way and it is difficult to take out the sheet.

本開示の一局面においては、ストッパが邪魔になりにくいシート搬送装置を提供することが望ましい。 In one aspect of the present disclosure, it is desirable to provide a sheet transfer device in which the stopper does not easily get in the way.

本開示の一態様は、シート搬送装置であって、シートを搬送する搬送部と、搬送部から排出される搬送済みのシートを支持する支持面を有する排出部と、排出部におけるシートの排出方向下流側において、シートが更に排出方向下流側へ移動するのを規制する第一ストッパとを備え、第一ストッパは、排出部に対して回動可能に取り付けられて、第一位置から第二位置を経て第三位置に至る範囲内を回動する回動部と、排出部に対してスライド可能に取り付けられるスライド部と、弾性変形に伴って生じる弾性力で、スライド部を一方向へ付勢する付勢部とを有し、スライド部は、付勢部によって付勢されて、その付勢力で回動部を押圧するように構成され、回動部は、少なくとも第三位置にある場合にシートの排出方向上流側から下流側に向かって上り勾配となる傾斜角をなす規制面を有し、排出部へと排出されるシートの排出方向先端に規制面で当接することによって該シートの移動を規制可能に構成され、しかも、回動部は、第三位置から第二位置を経て第一位置へと回動すると、支持面に対する規制面の傾斜角が減少して回動部の上方への突出量が小さくなるように構成され、さらに、回動部は、第三位置から第二位置までの範囲内にある場合には、回動部がスライド部から受ける押圧力で、第二位置から第三位置へと回動する向きに付勢されている。 One aspect of the present disclosure is a sheet transport device, which comprises a transport unit for transporting a sheet, a discharge unit having a support surface for supporting the transported sheet discharged from the transport unit, and a discharge direction of the sheet in the discharge unit. On the downstream side, a first stopper that regulates the movement of the seat further downstream in the discharge direction is provided, and the first stopper is rotatably attached to the discharge portion and is mounted from the first position to the second position. The sliding part is urged in one direction by the rotating part that rotates within the range to the third position through the above, the sliding part that is slidably attached to the discharging part, and the elastic force generated by the elastic deformation. The slide portion is configured to be urged by the urging portion and press the rotating portion with the urging force, and the rotating portion is at least in the third position. The sheet has a regulating surface having an inclination angle that makes an upward slope from the upstream side to the downstream side in the discharging direction of the sheet, and the sheet moves by contacting the tip of the sheet discharged to the discharging section in the discharging direction with the regulating surface. Moreover, when the rotating portion rotates from the third position to the first position via the second position, the inclination angle of the regulating surface with respect to the support surface decreases and moves upward of the rotating portion. In addition, when the rotating portion is within the range from the third position to the second position, the rotating portion receives a pressing force from the sliding portion to reduce the amount of protrusion of the rotating portion to the second position. It is urged to rotate from to the third position.

このように構成されたシート搬送装置によれば、第一ストッパを使用する場合には、回動部を第三位置へと回動させることにより、シートの移動を規制することができる。また、第一ストッパを使用しない場合には、回動部を第一位置へと回動させることにより、第一ストッパを邪魔にならない場所に配置することができる。回動部を第三位置へと回動させる際には、回動部を第二位置から第三位置までの範囲内へ回動させれば、回動部がスライド部から受ける押圧力で第三位置へと回動し、第三位置で保持される。 According to the sheet transport device configured as described above, when the first stopper is used, the movement of the sheet can be regulated by rotating the rotating portion to the third position. Further, when the first stopper is not used, the first stopper can be arranged in a place where it does not get in the way by rotating the rotating portion to the first position. When rotating the rotating part to the third position, if the rotating part is rotated within the range from the second position to the third position, the rotating part is subjected to the pressing force received from the slide part. It rotates to three positions and is held in the third position.

一方、利用者が排出部からシートを取り出す際には、回動部を第三位置から第二位置に向かって回動させれば、回動部の上方への突出量が小さくなる。したがって、排出部からシートを取り出す際に回動部が邪魔にならず、シートを取り出す作業が容易になり、シートと回動部との接触に起因するシートの損傷も抑制できる。しかも、排出部からシートを取り出された後は、回動部をスライド部からの押圧力で第三位置へ復帰させることができる。したがって、利用者が手作業で回動部を第三位置へ戻さなくても済み、その分だけ操作性が良好になり、回動部が中途半端な位置に留まるのを抑制することができる。 On the other hand, when the user takes out the sheet from the discharging portion, if the rotating portion is rotated from the third position to the second position, the amount of protrusion of the rotating portion upward is reduced. Therefore, when the sheet is taken out from the discharging part, the rotating part does not get in the way, the work of taking out the sheet becomes easy, and the damage of the sheet due to the contact between the sheet and the rotating part can be suppressed. Moreover, after the sheet is taken out from the discharge portion, the rotating portion can be returned to the third position by the pressing force from the slide portion. Therefore, it is not necessary for the user to manually return the rotating portion to the third position, and the operability is improved accordingly, and it is possible to prevent the rotating portion from staying in the halfway position.

The right receiving portion 43 has a claw-shaped portion protruding to the right from the right side surface of the right pedestal portion 45. The left hook portion 41 is hooked on the left receiving portion 43 as shown by the broken line arrow in FIG. The right hook portion 41 is hooked on the right receiving portion 43.

スライド部２４がジョイントカバー７に取り付けられる際、左右のフック部４１は、左右の台座部４５を左右両側から挟み込む位置に配置される。スライド部２４をジョイントカバー７に対して相対的に後方へとスライドさせた際には、フック部４１の板ばね状部分が弾性変形しつつ受け部４３の爪状部分を乗り越える。これにより、スライド部２４をジョイントカバー７に対して相対的に前方へとスライドさせた際には、フック部４１の爪状部分が受け部４３の爪状部分に引っ掛かり、スライド部２４の前方への変位が規制される状態となる（図８Ｂ参照。）。 When the slide portion 24 is attached to the joint cover 7, the left and right hook portions 41 are arranged at positions that sandwich the left and right pedestal portions 45 from both the left and right sides. When the slide portion 24 is slid rearward relative to the joint cover 7, the leaf spring-like portion of the hook portion 41 elastically deforms and gets over the claw-shaped portion of the receiving portion 43. As a result, when the slide portion 24 is slid forward relative to the joint cover 7, the claw-shaped portion of the hook portion 41 is caught by the claw-shaped portion of the receiving portion 43 and moves forward of the slide portion 24. The displacement of is regulated (see FIG. 8B).

このようにしてスライド部２４がジョイントカバー７に取り付けられた状態において、スライド部２４はガイド孔３７の上方を覆う位置に配置される。そのため、何らかの事情で複合機１に水等の液体がかかったとしても、ガイド孔３７に液体が直接かかるのをスライド部２４によって防ぐことができる。また、台座部４５は、凹部３１の底よりも高い位置にある。そのため、上述のような液体がスライド部２４やその周囲にある部分を伝って凹部３１の内側へ入り込んだとしても、その液体が台座部４５の上面に達するほど大量でなければ、ガイド孔３７を通じて装置内へ液体が浸入するのを台座部４５によって防ぐことができる。 In the state where the slide portion 24 is attached to the joint cover 7 in this way, the slide portion 24 is arranged at a position that covers the upper part of the guide hole 37. Therefore, even if the multifunction device 1 is splashed with a liquid such as water for some reason, the slide portion 24 can prevent the liquid from being directly splashed on the guide hole 37. Further, the pedestal portion 45 is located higher than the bottom of the recess 31. Therefore, even if the above-mentioned liquid enters the inside of the recess 31 through the slide portion 24 and the portion around the slide portion 24, if the liquid is not large enough to reach the upper surface of the pedestal portion 45, the liquid is passed through the guide hole 37. The pedestal portion 45 can prevent the liquid from entering the device.

スライド部２４において、排出部８へと排出される被記録媒体に接触し得る箇所には、上向きに突出する複数のリブ４７が形成されている（図４参照。）。本実施形態の場合は、リブ４７が設けられることにより、スライド部２４における被記録媒体の排出方向下流側端部２４１の高さ位置は、第三位置（図６Ｂ参照。）にある回動部２３における被記録媒体の排出方向上流側端部２３１と同じ高さ位置以上となるように構成されている。 A plurality of ribs 47 projecting upward are formed in the slide portion 24 at a portion where the recording medium discharged to the discharge portion 8 can come into contact with the recording medium (see FIG. 4). In the case of the present embodiment, by providing the rib 47, the height position of the downstream end portion 241 of the recorded medium in the discharge direction in the slide portion 24 is the rotating portion at the third position (see FIG. 6B). It is configured so as to be at the same height position or higher as the upstream end portion 231 of the recording medium in the discharge direction in No. 23.

付勢部２５は、弾性変形に伴って生じる弾性力で、スライド部２４を一方向（図６Ａ及び図６Ｂ中でいう前方。）へ付勢している。本実施形態の場合、付勢部２５は、コイルスプリングを利用した圧縮ばねによって構成されている。スライド部２４は、付勢部２５によって図６Ａ及び図６Ｂ中でいう前方に向かって付勢され、その付勢力で回動部２３を押圧するように構成されている。 The urging portion 25 urges the slide portion 24 in one direction (forward in FIGS. 6A and 6B) by the elastic force generated by the elastic deformation. In the case of the present embodiment, the urging portion 25 is composed of a compression spring using a coil spring. The slide portion 24 is urged by the urging portion 25 toward the front as referred to in FIGS. 6A and 6B, and the rotating portion 23 is pressed by the urging force.

ただし、スライド部２４が付勢部２５によって付勢されて前方へスライドすると、フック部４１が受け部４３に引っ掛かる（図８Ｂ参照。）。この状態に至ると、スライド部２４が、更に前方へ変位することはなく、付勢部２５からスライド部２４へと作用する付勢力は、スライド部２４を介して受け部４３に作用する状態になる。なお、この状態において、回動部２３は第三位置にあり、自重によって第三位置から第一位置へ回動する方向へと付勢される。そのため、回動部２３とスライド部２４は、回動部２３の自重による付勢力により、互いに接触する状態が維持される。一方、回動部２３が第一位置にある場合、スライド部２４は、回動部２３に当接する。このとき、付勢部２５からスライド部２４へ
と作用する付勢力は、スライド部２４を介して回動部２３に作用する状態になる。また、フック部４１は、受け部４３から離れる位置まで後退する（図８Ａ参照。）。 However, when the slide portion 24 is urged by the urging portion 25 and slides forward, the hook portion 41 is caught by the receiving portion 43 (see FIG. 8B). When this state is reached, the slide portion 24 is not further displaced forward, and the urging force acting from the urging portion 25 to the slide portion 24 acts on the receiving portion 43 via the slide portion 24. Become. In this state, the rotating portion 23 is in the third position and is urged by its own weight in the direction of rotating from the third position to the first position. Therefore, the rotating portion 23 and the sliding portion 24 are maintained in a state of being in contact with each other due to the urging force of the rotating portion 23 due to its own weight. On the other hand, when the rotating portion 23 is in the first position, the sliding portion 24 comes into contact with the rotating portion 23. At this time, the urging force acting from the urging portion 25 to the slide portion 24 is in a state of acting on the rotating portion 23 via the slide portion 24. Further, the hook portion 41 retracts to a position away from the receiving portion 43 (see FIG. 8A).

回動部２３は、第三位置（図６Ｂ参照。）から第二位置（図７参照。）までの範囲内にある場合には、回動部２３がスライド部２４から受ける押圧力で、第二位置から第三位置へと回動する向き（図６Ｂにおいて時計回りとなる向き。）に付勢されている。また、回動部２３は、第一位置（図６Ａ参照。）から第二位置（図７参照。）までの範囲内にある場合には、回動部２３がスライド部２４から受ける押圧力で、第二位置から第一位置へと回動する向き（図６Ａにおいて反時計回りとなる向き。）に付勢されている。 When the rotating portion 23 is within the range from the third position (see FIG. 6B) to the second position (see FIG. 7), the rotating portion 23 is subjected to the pressing force received from the slide portion 24 to obtain the second position. It is urged to rotate from the second position to the third position (clockwise in FIG. 6B). Further, when the rotating portion 23 is within the range from the first position (see FIG. 6A) to the second position (see FIG. 7), the rotating portion 23 receives a pressing force from the slide portion 24. , It is urged in the direction of rotation from the second position to the first position (the direction of counterclockwise in FIG. 6A).

より詳しく説明すると、本実施形態の場合、図７に示すように、回動部２３は、第一エッジ５１と、第一エッジ５１を挟んで両側に形成された第一面６１及び第二面６２を有する形状とされている。また、スライド部２４は、第二エッジ５２と、第二エッジ５２を挟んで両側に形成された第三面６３及び第四面６４を有する形状とされている。回動部２３及びスライド部２４は、回動部２３が第二位置（図７参照。）にある場合に、第一エッジ５１と第二エッジ５２とが接触する位置関係にある。この位置関係にある場合には、スライド部２４から回動部２３に対して作用する付勢力の向きが、第一エッジ５１と第二エッジ５２との接触点から回動部２３の回動中心に至る向きとなり、回動部２３には回転モーメントが生じない。 More specifically, in the case of the present embodiment, as shown in FIG. 7, the rotating portion 23 includes the first edge 51 and the first surface 61 and the second surface formed on both sides of the first edge 51. It has a shape having 62. Further, the slide portion 24 has a shape having a second edge 52 and a third surface 63 and a fourth surface 64 formed on both sides of the second edge 52. The rotating portion 23 and the sliding portion 24 are in a positional relationship in which the first edge 51 and the second edge 52 come into contact with each other when the rotating portion 23 is in the second position (see FIG. 7). In this positional relationship, the direction of the urging force acting from the slide portion 24 to the rotating portion 23 is the rotation center of the rotating portion 23 from the contact point between the first edge 51 and the second edge 52. No rotational moment is generated in the rotating portion 23.

一方、本実施形態の場合、スライド部２４の押圧方向（図７中でいう前方向。）に対する第一面６１の傾斜角は、回動部２３を第二位置（図７参照。）から第一位置（図６Ａ参照。）に向かって回動させた際に、スライド部２４の第二エッジ５２で回動部２３の第一面６１を押圧すると、回動部２３が第一位置（図６Ａ参照。）へと付勢される傾斜角とされている。すなわち、スライド部２４の第二エッジ５２で回動部２３の第一面６１を押圧した際、第一面６１には、第一面６１に沿ったせん断応力や第一面６１に垂直な垂直応力等が作用するが、その垂直応力の一部（分力）が、他の応力に起因する摩擦抵抗等を上回って回動部２３に反時計回りの回転モーメントが生じるように、第一面６１の傾きが設定されている。 On the other hand, in the case of the present embodiment, the inclination angle of the first surface 61 with respect to the pressing direction (forward direction in FIG. 7) of the slide portion 24 is such that the rotating portion 23 is located at the second position (see FIG. 7). When the first surface 61 of the rotating portion 23 is pressed by the second edge 52 of the slide portion 24 when the rotating portion 23 is rotated toward one position (see FIG. 6A), the rotating portion 23 is moved to the first position (FIG. 6A). It is said that the inclination angle is urged to 6A.). That is, when the first surface 61 of the rotating portion 23 is pressed by the second edge 52 of the slide portion 24, the first surface 61 is subjected to shear stress along the first surface 61 and normal to the first surface 61. Although stress or the like acts, the first surface is such that a part (component force) of the normal stress exceeds the frictional resistance or the like caused by other stresses and a counterclockwise rotational moment is generated in the rotating portion 23. The inclination of 61 is set.

なお、本実施形態の場合は、スライド部２４の第二エッジ５２が回動部２３の第一面６１を押圧する位置関係にあるので、上述のような構成になっている。ただし、スライド部２４の第三面６３が回動部２３の第一エッジ５１を押圧する位置関係にある場合には、スライド部２４の押圧方向に対する第三面６３の傾斜角が、回動部２３を第二位置から第一位置に向かって回動させた際に、スライド部２４の第三面６３で回動部２３の第一エッジ５１を押圧すると、回動部２３が第一位置へと付勢される傾斜角とされていればよい。 In the case of the present embodiment, the second edge 52 of the slide portion 24 has a positional relationship of pressing the first surface 61 of the rotating portion 23, so that the configuration is as described above. However, when the third surface 63 of the slide portion 24 is in a positional relationship of pressing the first edge 51 of the rotating portion 23, the inclination angle of the third surface 63 with respect to the pressing direction of the slide portion 24 is the rotating portion. When the 23 is rotated from the second position to the first position, when the first edge 51 of the rotating portion 23 is pressed by the third surface 63 of the slide portion 24, the rotating portion 23 moves to the first position. It suffices if the inclination angle is urged.

また、本実施形態の場合、スライド部２４の押圧方向（図７中でいう前方向。）に対する第四面６４の傾斜角は、回動部２３を第二位置（図７参照。）から第三位置（図６Ｂ参照。）に向かって回動させた際に、スライド部２４の第四面６４で回動部２３の第一エッジ５１を押圧すると、回動部２３が第三位置（図６Ｂ参照。）へと付勢される傾斜角とされている。 Further, in the case of the present embodiment, the inclination angle of the fourth surface 64 with respect to the pressing direction (forward direction in FIG. 7) of the slide portion 24 is such that the rotating portion 23 is located at the second position (see FIG. 7). When the first edge 51 of the rotating portion 23 is pressed by the fourth surface 64 of the slide portion 24 when the rotating portion 23 is rotated toward the three positions (see FIG. 6B), the rotating portion 23 is moved to the third position (FIG. 6B). It is said that the inclination angle is urged to 6B.).

すなわち、スライド部２４の第四面６４で回動部２３の第一エッジ５１を押圧した際、第一エッジ５１には、第一エッジ５１における接線方向に沿ったせん断応力や第一エッジ５１における接線方向に垂直な垂直応力等が作用するが、その垂直応力の一部（分力）が、他の応力に起因する摩擦抵抗等を上回って回動部２３に時計回りの回転モーメントが生じるように、第四面６４の傾きが設定されている。 That is, when the first edge 51 of the rotating portion 23 is pressed by the fourth surface 64 of the slide portion 24, the first edge 51 receives the shear stress along the tangential direction of the first edge 51 and the first edge 51. A normal stress or the like perpendicular to the tangential direction acts, but a part (component force) of the normal stress exceeds the frictional resistance or the like caused by other stresses so that a clockwise rotational moment is generated in the rotating portion 23. The inclination of the fourth surface 64 is set to 1.

なお、本実施形態の場合は、スライド部２４の第四面６４が回動部２３の第一エッジ５
１を押圧する位置関係にあるので、上述のような構成になっている。ただし、スライド部２４の第二エッジ５２が回動部２３の第二面６２を押圧する位置関係にある場合には、スライド部２４の押圧方向に対する第二面６２の傾斜角が、回動部２３を第二位置から第三位置に向かって回動させた際に、スライド部２４の第二エッジ５２で回動部２３の第二面６２を押圧すると、回動部２３が第三位置へと付勢される傾斜角とされていればよい。 In the case of this embodiment, the fourth surface 64 of the slide portion 24 is the first edge 5 of the rotating portion 23.
Since there is a positional relationship in which 1 is pressed, the configuration is as described above. However, when the second edge 52 of the slide portion 24 is in a positional relationship of pressing the second surface 62 of the rotating portion 23, the inclination angle of the second surface 62 with respect to the pressing direction of the sliding portion 24 is the rotating portion. When the 23 is rotated from the second position to the third position, when the second surface 62 of the rotating portion 23 is pressed by the second edge 52 of the slide portion 24, the rotating portion 23 moves to the third position. It suffices if the inclination angle is urged.

第二ストッパ２２は、排出部８における被記録媒体の排出方向（図２における前方。）に直交する被記録媒体の幅方向（図２における左右方向。）の両側において第一ストッパ２１を挟む位置に設けられている。第二ストッパ２２は、排出部８における被記録媒体の支持面よりも上方へ突出している。第二ストッパ２２の上面には、被記録媒体の排出方向上流側から下流側に向かって（図２中でいう前方に向かって）上り勾配となる傾斜角が付与されている。また、第二ストッパ２２の上端は、第二位置（図６Ａ中に破線で示す位置参照。）にある回動部２３よりも高い位置にある。 The second stopper 22 is positioned to sandwich the first stopper 21 on both sides of the recording medium in the width direction (left-right direction in FIG. 2) orthogonal to the discharge direction (front in FIG. 2) of the recording medium in the discharge unit 8. It is provided in. The second stopper 22 projects upward from the support surface of the recording medium in the discharge unit 8. The upper surface of the second stopper 22 is provided with an inclination angle that makes an upward slope from the upstream side to the downstream side (toward the front in FIG. 2) of the recording medium in the discharge direction. Further, the upper end of the second stopper 22 is located higher than the rotating portion 23 at the second position (see the position shown by the broken line in FIG. 6A).

［効果］
以上説明したような複合機１によれば、第一ストッパ２１を使用する場合には、回動部２３を第三位置（図６Ｂ参照。）へと回動させることにより、被記録媒体の移動を規制することができる。また、第一ストッパ２１を使用しない場合には、回動部２３を第一位置（図６Ａ参照。）へと回動させることにより、第一ストッパ２１を邪魔にならない場所に配置することができる。回動部２３を第三位置へと回動させる際には、回動部２３を第二位置（図７参照。）から第三位置（図６Ｂ参照。）までの範囲内へ回動させれば、回動部２３がスライド部２４から受ける押圧力で第三位置へと回動し、第三位置で保持される。 [effect]
According to the multifunction device 1 as described above, when the first stopper 21 is used, the recording medium is moved by rotating the rotating portion 23 to the third position (see FIG. 6B). Can be regulated. Further, when the first stopper 21 is not used, the first stopper 21 can be arranged in an unobtrusive place by rotating the rotating portion 23 to the first position (see FIG. 6A). .. When rotating the rotating portion 23 to the third position, the rotating portion 23 is rotated within the range from the second position (see FIG. 7) to the third position (see FIG. 6B). For example, the rotating portion 23 rotates to the third position by the pressing force received from the slide portion 24, and is held at the third position.

一方、利用者が排出部８から被記録媒体を取り出す際には、回動部２３を第三位置（図６Ｂ参照。）から第二位置（図７参照。）に向かって回動させれば、回動部２３の上方への突出量が小さくなる。したがって、排出部８から被記録媒体を取り出す際に回動部２３が邪魔にならず、被記録媒体を取り出す作業が容易になり、被記録媒体と回動部２３との接触に起因する被記録媒体の損傷も抑制できる。しかも、排出部８から被記録媒体を取り出された後は、回動部２３をスライド部２４からの押圧力で第三位置へ復帰させることができる。したがって、利用者が手作業で回動部２３を第三位置へ戻さなくても済み、その分だけ操作性が良好になり、回動部２３が中途半端な位置（例えば、第二位置付近。）に留まるのを抑制することができる。 On the other hand, when the user takes out the recording medium from the discharge unit 8, the rotating unit 23 can be rotated from the third position (see FIG. 6B) to the second position (see FIG. 7). , The amount of protrusion of the rotating portion 23 upward is reduced. Therefore, the rotating unit 23 does not get in the way when the recording medium is taken out from the discharging unit 8, the work of taking out the recording medium becomes easy, and the recording is caused by the contact between the recording medium and the rotating unit 23. Damage to the medium can also be suppressed. Moreover, after the recording medium is taken out from the discharge unit 8, the rotating unit 23 can be returned to the third position by the pressing force from the slide unit 24. Therefore, the user does not have to manually return the rotating portion 23 to the third position, and the operability is improved accordingly, and the rotating portion 23 is in a halfway position (for example, near the second position). ) Can be suppressed.

なお、本実施形態の場合、回動部２３が第三位置にある場合、上方への突出量は、第二ストッパ２２を上回る。また、回動部２３が第一位置にある場合、上方への突出量は、第二ストッパ２２を下回る。したがって、排出部８へ排出される被記録媒体の枚数が多い場合には、回動部２３を第三位置へ変位させることが好ましい。一方、回動部２３が第一位置にある場合でも、第二ストッパ２２は上方へ突出する状態にある。したがって、排出部８へ排出される被記録媒体の枚数が少ない場合には、回動部２３が第一位置にある状態であっても、第二ストッパ２２だけでシートストッパ９としての役割を果たすことができる。 In the case of the present embodiment, when the rotating portion 23 is in the third position, the amount of protrusion upward exceeds the second stopper 22. Further, when the rotating portion 23 is in the first position, the amount of protrusion upward is less than that of the second stopper 22. Therefore, when the number of recording media discharged to the discharging unit 8 is large, it is preferable to displace the rotating unit 23 to the third position. On the other hand, even when the rotating portion 23 is in the first position, the second stopper 22 is in a state of protruding upward. Therefore, when the number of recording media discharged to the discharging unit 8 is small, the second stopper 22 alone serves as the seat stopper 9 even when the rotating unit 23 is in the first position. be able to.

また、本実施形態の場合、回動部２３を第一位置（図６Ａ参照。）から第二位置（図７参照。）までの範囲内へ回動させれば、回動部２３がスライド部２４から受ける押圧力で第一位置へと回動し、第一位置で保持される。この状態においては、回動部２３の上方への突出量が最も小さくなる。したがって、回動部２３を使用しない場合には、回動部２３を第一位置へ回動させることにより、回動部２３が邪魔にならないようにすることができ、その際、利用者が手作業で回動部２３を第一位置へ移動させなくても済み、その分だけ操作性が良好になり、回動部２３が中途半端な位置（例えば、第二位置付近。）に留まるのを抑制することができる。 Further, in the case of the present embodiment, if the rotating portion 23 is rotated within the range from the first position (see FIG. 6A) to the second position (see FIG. 7), the rotating portion 23 slides. It rotates to the first position by the pressing force received from 24 and is held at the first position. In this state, the amount of protrusion of the rotating portion 23 upward is the smallest. Therefore, when the rotating portion 23 is not used, the rotating portion 23 can be rotated to the first position so that the rotating portion 23 does not get in the way. It is not necessary to move the rotating portion 23 to the first position during the work, and the operability is improved accordingly, so that the rotating portion 23 stays at a halfway position (for example, near the second position). It can be suppressed.

また、本実施形態の場合、利用者が排出部８から被記録媒体を取り出す際に、回動部２３が被記録媒体に押されて第三位置から第二位置に向かって回動したとしても、被記録媒体が第二ストッパ２２に接触すると、それ以上は回動部２３が第二位置に向かって押されなくなる。そのため、被記録媒体の取り出し作業によって、回動部２３が第二位置を超えて第一位置に近づくのを抑制でき、回動部２３が無駄に第一位置へと回動してしまうのを抑制できる。 Further, in the case of the present embodiment, even if the rotating unit 23 is pushed by the recording medium and rotates from the third position to the second position when the user takes out the recording medium from the discharge unit 8. When the recording medium comes into contact with the second stopper 22, the rotating portion 23 is no longer pushed toward the second position. Therefore, it is possible to prevent the rotating portion 23 from exceeding the second position and approaching the first position by the work of taking out the recording medium, and the rotating portion 23 is unnecessarily rotated to the first position. Can be suppressed.

また、本実施形態の場合、上述のような位置決め部３３が設けられているので、回動部２３を第三位置に適正に位置決めすることができる。
また、本実施形態の場合、スライド部２４の端部２４１が、第三位置にある回動部２３の端部２３１以上の高い位置にあるので、スライド部２４の端部を通過する被記録媒体の先端が、回動部２３の端部２３１に引っ掛かるのを抑制することができる。 Further, in the case of the present embodiment, since the positioning portion 33 as described above is provided, the rotating portion 23 can be appropriately positioned at the third position.
Further, in the case of the present embodiment, since the end portion 241 of the slide portion 24 is at a higher position than the end portion 231 of the rotating portion 23 at the third position, the recording medium that passes through the end portion of the slide portion 24. It is possible to prevent the tip of the rotating portion 23 from being caught by the end portion 231 of the rotating portion 23.

また、本実施形態の場合、スライド部２４に上述のようなリブ４７が形成されているので、スライド部２４と被記録媒体との接触面積を少なくし、被記録媒体をスムーズに排出できる。 Further, in the case of the present embodiment, since the rib 47 as described above is formed in the slide portion 24, the contact area between the slide portion 24 and the recording medium can be reduced, and the recording medium can be smoothly discharged.

また、本実施形態の場合、上述のような受け部４３が設けられているので、第三位置にある回動部２３にはスライド部２４から過大な付勢力は作用せず、回動部２３に不要な負荷がかかることを抑制できる。 Further, in the case of the present embodiment, since the receiving portion 43 as described above is provided, an excessive urging force does not act from the slide portion 24 on the rotating portion 23 at the third position, and the rotating portion 23 does not act. It is possible to prevent unnecessary load from being applied to the slide.

（２）第二実施形態
次に、第二実施形態について説明する。なお、第二実施形態以降の実施形態は、第一実施形態で例示した構成の一部を変更しただけなので、第一実施形態との相違点を中心に詳述し、第一実施形態と同様な部分に関しては、その詳細な説明を省略する。また、第一実施形態で示した各構成と機能的に見て同等な構成には、第一実施形態で示した符号と同じ符号を付す。 (2) Second Embodiment Next, the second embodiment will be described. In the second and subsequent embodiments, only a part of the configuration illustrated in the first embodiment has been changed. Therefore, the differences from the first embodiment will be described in detail, and the same as the first embodiment. A detailed description of the above-mentioned parts will be omitted. Further, a configuration functionally equivalent to each configuration shown in the first embodiment is designated by the same reference numeral as that shown in the first embodiment.

第二実施形態では、回動部２３が、第一位置（図９Ａ参照。）から第二位置（図示略。）までの範囲内にある場合に、回動部２３がスライド部２４から押圧力を受けても、第二位置から第一位置へと回動する向き（図９Ａにおいて反時計回りとなる向き。）には付勢されない点で、第一実施形態とは相違する。 In the second embodiment, when the rotating portion 23 is within the range from the first position (see FIG. 9A) to the second position (not shown), the rotating portion 23 presses the sliding portion 24. Even if it receives, it is different from the first embodiment in that it is not urged in the direction of rotation from the second position to the first position (the direction of counterclockwise in FIG. 9A).

第二実施形態においては、回動部２３が第一位置（図９Ａ参照。）から第二位置（図示略。）までの範囲内にある場合に、スライド部２４の垂直面６６が回動部２３の第一エッジ５１を押圧する位置関係にある。ただし、スライド部２４の押圧方向に対する垂直面６６の傾斜角は、回動部２３を第二位置から第一位置に向かって回動させた際に、スライド部２４の垂直面６６で回動部２３の第一エッジ５１を押圧しても、回動部２３が第一位置へと付勢されることがない角度となっている。 In the second embodiment, when the rotating portion 23 is within the range from the first position (see FIG. 9A) to the second position (not shown), the vertical surface 66 of the slide portion 24 is the rotating portion. There is a positional relationship in which the first edge 51 of 23 is pressed. However, the inclination angle of the vertical surface 66 with respect to the pressing direction of the slide portion 24 is such that when the rotating portion 23 is rotated from the second position to the first position, the rotating portion is formed on the vertical surface 66 of the slide portion 24. Even if the first edge 51 of the 23 is pressed, the rotating portion 23 is at an angle that is not urged to the first position.

すなわち、スライド部２４の垂直面６６で回動部２３の第一エッジ５１を押圧した際、第一エッジ５１に作用する応力の一部（分力）は、回動部２３に反時計回りの回転モーメントを生じさせ得る。ただし、回動部２３が反時計回りに回動するには、第一エッジ５１がスライド部２４の垂直面６６に沿って摺動するので、第一エッジ５１と垂直面６６との間には摩擦抵抗が生じる。垂直面６６の角度は、上述のような摩擦抵抗によって回動部２３が反時計回りには回動しなくなるような角度に該当する。 That is, when the first edge 51 of the rotating portion 23 is pressed by the vertical surface 66 of the sliding portion 24, a part (component force) of the stress acting on the first edge 51 is counterclockwise to the rotating portion 23. A rotational moment can be generated. However, in order for the rotating portion 23 to rotate counterclockwise, the first edge 51 slides along the vertical surface 66 of the sliding portion 24, so that there is a gap between the first edge 51 and the vertical surface 66. Friction resistance occurs. The angle of the vertical surface 66 corresponds to an angle at which the rotating portion 23 does not rotate counterclockwise due to the frictional resistance as described above.

このように構成されたシートストッパ９の場合は、利用者が手動操作で回動部２３を第一位置へと変位させることになる。一方、回動部２３を第三位置へと変位させる場合には
、第一実施形態の場合と同様の操作をすればよく、回動部２３を第二位置と第三位置との間となる位置まで変位させれば、スライド部２４から受ける力で回動部２３が第三位置へと変位する。 In the case of the seat stopper 9 configured in this way, the user manually displaces the rotating portion 23 to the first position. On the other hand, when the rotating portion 23 is displaced to the third position, the same operation as in the case of the first embodiment may be performed, and the rotating portion 23 is placed between the second position and the third position. If it is displaced to the position, the rotating portion 23 is displaced to the third position by the force received from the slide portion 24.

なお、第二実施形態において、回動部２３及び排出部８には、回動部２３が第一位置へ変位した時点で互いに軽く噛み合う凹凸を設けてある。このように構成すれば、回動部２３を手動操作で第一位置へ変位させた際、回動部２３が第一位置へ変位した瞬間に凹凸が噛み合うので、回動部２３を第一位置へ変位させた際にスナップ感がある構造（すなわち、カチッと第一位置に位置決めされる感触がある構造。）にすることができる。 In the second embodiment, the rotating portion 23 and the discharging portion 8 are provided with irregularities that lightly mesh with each other when the rotating portion 23 is displaced to the first position. With this configuration, when the rotating portion 23 is manually displaced to the first position, the unevenness meshes at the moment when the rotating portion 23 is displaced to the first position, so that the rotating portion 23 is placed in the first position. It is possible to have a structure that gives a snap feeling when displaced to (that is, a structure that gives a feeling of being positioned in the first position with a click).

（３）第三実施形態
次に、第三実施形態について説明する。第三実施形態は、図１０Ａ及び図１０Ｂに示すように、規制部材７１が設けられている点、及び第二ストッパ２２の上方向への突出量が第二実施形態よりも小さくされている（すなわち、高さ方向寸法が低くされている。）点で、第二実施形態とは相違する。 (3) Third Embodiment Next, the third embodiment will be described. In the third embodiment, as shown in FIGS. 10A and 10B, the point where the regulating member 71 is provided and the amount of protrusion of the second stopper 22 in the upward direction are smaller than those in the second embodiment (as shown in the second embodiment). That is, it differs from the second embodiment in that the dimension in the height direction is lowered.)

規制部材７１は、回動部２３に対して回動可能に取り付けられ、図１０Ａに示す非規制位置と図１０Ｂに示す規制位置との間で変位可能に構成されている。規制部材７１が図１０Ｂに示す規制位置にある場合、規制部材７１は、回動部２３が第二位置から第一位置までの範囲内に回動するのを規制する。また、規制部材７１が図１０Ａに示す規制位置にある場合、規制部材７１は、回動部２３が第二位置から第一位置までの範囲内に回動するのを規制しない。 The regulating member 71 is rotatably attached to the rotating portion 23 and is configured to be displaceable between the non-regulated position shown in FIG. 10A and the regulated position shown in FIG. 10B. When the restricting member 71 is in the restricted position shown in FIG. 10B, the restricting member 71 restricts the rotating portion 23 from rotating within the range from the second position to the first position. Further, when the regulating member 71 is in the regulated position shown in FIG. 10A, the regulating member 71 does not restrict the rotating portion 23 from rotating within the range from the second position to the first position.

本実施形態の場合、規制部材７１は、回動部２３が第三位置（図１０Ｂ参照。）へと回動する際に、規制部材７１の自重で回動して回動部２３から垂れ下がり、その垂れ下がった下端で排出部８に当接することにより、回動部２３が第二位置から第一位置までの範囲内に回動するのを規制する。回動部２３を第三位置から第一位置へと変位させたい場合には、利用者は回動部２３を操作する際に規制部材７１も操作して、規制部材７１を非規制位置へと回動させつつ、回動部２３を第三位置から第一位置へと回動させる。 In the case of the present embodiment, when the rotating portion 23 rotates to the third position (see FIG. 10B), the regulating member 71 rotates under its own weight of the regulating member 71 and hangs down from the rotating portion 23. By contacting the discharging portion 8 at the hanging lower end, the rotating portion 23 is restricted from rotating within the range from the second position to the first position. When the user wants to displace the rotating portion 23 from the third position to the first position, the user also operates the regulating member 71 when operating the rotating portion 23 to move the regulating member 71 to the non-regulated position. While rotating, the rotating portion 23 is rotated from the third position to the first position.

このように構成されていれば、規制部材７１を規制位置へ変位させることにより、回動部２３が第一位置へ回動するのを抑制することができる。したがって、第一実施形態及び第二実施形態とは異なり、回動部２３が第一位置へ回動するのを第二ストッパ２２によって抑制しなくても済むので、第二ストッパ２２の上方向への突出量を小さめにすることも可能となる。よって、第二ストッパ２２の突出量を小さくしたい場合には、上述のような規制部材７１を設けると有効である。 With such a configuration, by displacing the regulating member 71 to the regulated position, it is possible to prevent the rotating portion 23 from rotating to the first position. Therefore, unlike the first embodiment and the second embodiment, it is not necessary to suppress the rotation of the rotating portion 23 to the first position by the second stopper 22, so that the second stopper 22 does not have to be rotated upward. It is also possible to reduce the amount of protrusion of. Therefore, when it is desired to reduce the amount of protrusion of the second stopper 22, it is effective to provide the regulation member 71 as described above.

また、上記規制部材７１の場合、回動部２３を第三位置へ回動させれば、規制部材７１が自重で垂れ下がって、回動部２３が第二位置から第一位置までの範囲内に回動するのを規制する状態になる。よって、利用者が規制部材７１を規制位置へ変位させる操作をしなくても済むので、操作性が良好になる。 Further, in the case of the regulation member 71, if the rotating portion 23 is rotated to the third position, the regulating member 71 hangs down by its own weight, and the rotating portion 23 falls within the range from the second position to the first position. It will be in a state of restricting rotation. Therefore, it is not necessary for the user to perform an operation of displace the regulating member 71 to the regulated position, so that the operability is improved.

なお、本実施形態において、規制部材７１は、回動部２３が第三位置へと回動する際に、規制部材２３の自重で回動して回動部２３から垂れ下がるが、その垂れ下がった時点で規制部材２３の下端が排出部８に当接するように構成するか否かは任意である。すなわち、規制部材２３の下端は、回動部２３に荷重がかかって回動部２３が第二位置へ向かって回動した時点で排出部８に当接してもよく、このように構成されていても、回動部２３が第二位置から第一位置までの範囲内に回動するのを規制することができる。 In the present embodiment, when the rotating portion 23 rotates to the third position, the regulating member 71 rotates under the weight of the regulating member 23 and hangs down from the rotating portion 23. It is optional whether or not the lower end of the regulation member 23 is configured to come into contact with the discharge portion 8. That is, the lower end of the regulating member 23 may come into contact with the discharging portion 8 when the rotating portion 23 is loaded and the rotating portion 23 rotates toward the second position, and is configured in this way. However, it is possible to restrict the rotating portion 23 from rotating within the range from the second position to the first position.

（５）補足
なお、以上説明した例示的な実施形態から明らかなように、本開示のシート搬送装置は、更に以下に挙げるような構成を備えていてもよい。 (5) Supplement As is clear from the exemplary embodiments described above, the sheet transport device of the present disclosure may further include the following configurations.

まず、本開示のシート搬送装置において、回動部は、第一位置から第二位置までの範囲内にある場合には、回動部がスライド部から受ける押圧力で、第二位置から第一位置へと回動する向きに付勢されていてもよい。 First, in the sheet transporting device of the present disclosure, when the rotating portion is within the range from the first position to the second position, the rotating portion receives a pressing force from the sliding portion, and the rotating portion is first from the second position. It may be urged in a direction that rotates to a position.

このように構成されたシート搬送装置によれば、回動部を第一位置から第二位置までの範囲内へ回動させれば、回動部がスライド部から受ける押圧力で第一位置へと回動し、第一位置で保持される。この状態においては、回動部の上方への突出量が最も小さくなる。したがって、回動部を使用しない場合には、回動部を第一位置へ回動させることにより、回動部が邪魔にならないようにすることができ、その際、利用者が手作業で回動部を第一位置へ移動させなくても済み、その分だけ操作性が良好になり、回動部が中途半端な位置に留まるのを抑制することができる。 According to the sheet transport device configured in this way, if the rotating portion is rotated within the range from the first position to the second position, the rotating portion moves to the first position by the pressing force received from the sliding portion. And is held in the first position. In this state, the amount of protrusion of the rotating portion upward is the smallest. Therefore, when the rotating portion is not used, the rotating portion can be rotated to the first position so that the rotating portion does not get in the way, and at that time, the user manually rotates the rotating portion. It is not necessary to move the moving portion to the first position, and the operability is improved accordingly, and it is possible to prevent the rotating portion from staying at a halfway position.

また、本開示のシート搬送装置において、回動部は、第一エッジを挟んで両側に形成された第一面及び第二面を有し、スライド部は、第二エッジを挟んで両側に形成された第三面及び第四面を有し、回動部及びスライド部は、回動部が第二位置にある場合に、第一エッジと第二エッジとが接触する位置関係にあり、スライド部の押圧方向に対する第一面の傾斜角が、回動部を第二位置から第一位置に向かって回動させた際に、スライド部の第二エッジで回動部の第一面を押圧すると、回動部が第一位置へと付勢される傾斜角とされるか、スライド部の押圧方向に対する第三面の傾斜角が、回動部を第二位置から第一位置に向かって回動させた際に、スライド部の第三面で回動部の第一エッジを押圧すると、回動部が第一位置へと付勢される傾斜角とされており、スライド部の押圧方向に対する第二面の傾斜角が、回動部を第二位置から第三位置に向かって回動させた際に、スライド部の第二エッジで回動部の第二面を押圧すると、回動部が第三位置へと付勢される傾斜角とされるか、スライド部の押圧方向に対する第四面の傾斜角が、回動部を第二位置から第三位置に向かって回動させた際に、スライド部の第四面で回動部の第一エッジを押圧すると、回
動部が第三位置へと付勢される傾斜角とされていてもよい。 Further, in the sheet transport device of the present disclosure, the rotating portion has a first surface and a second surface formed on both sides of the first edge, and the sliding portion is formed on both sides of the second edge. The rotating portion and the sliding portion are in a positional relationship in which the first edge and the second edge come into contact with each other when the rotating portion is in the second position. The inclination angle of the first surface with respect to the pressing direction of the portion presses the first surface of the rotating portion with the second edge of the sliding portion when the rotating portion is rotated from the second position to the first position. Then, the tilt angle is set so that the rotating portion is urged to the first position, or the tilt angle of the third surface with respect to the pressing direction of the slide portion causes the rotating portion to move from the second position to the first position. When the first edge of the rotating portion is pressed by the third surface of the sliding portion during rotation, the rotating portion has an inclination angle that is urged to the first position, and the pressing direction of the sliding portion is set. When the second surface of the sliding portion is pressed with the second edge of the sliding portion when the rotating portion is rotated from the second position to the third position, the inclination angle of the second surface is rotated. The tilt angle is such that the portion is urged to the third position, or the tilt angle of the fourth surface with respect to the pressing direction of the slide portion causes the rotating portion to rotate from the second position to the third position. At that time, when the first edge of the rotating portion is pressed by the fourth surface of the sliding portion, the rotating portion may have an inclination angle that is urged to the third position.

このように構成されたシート搬送装置によれば、回動部及びスライド部に上述のような第一エッジ、第二エッジ、第一面、第二面、第三面、及び第四面を設けることにより、回動部を所期の方向へ付勢することができる。 According to the sheet transport device configured as described above, the rotating portion and the sliding portion are provided with the first edge, the second edge, the first surface, the second surface, the third surface, and the fourth surface as described above. Thereby, the rotating portion can be urged in the desired direction.

May also be in a high position.

このように構成されたシート搬送装置によれば、利用者が排出部からシートを取り出す際に、回動部がシートに押されて第三位置から第二位置に向かって回動したとしても、シートが第二ストッパに接触すると、それ以上は回動部が第二位置に向かって押されなくなる。そのため、シートの取り出し作業によって、回動部が第二位置を超えて第一位置に近づくのを抑制でき、回動部が無駄に第一位置へと回動してしまうのを抑制できる。 According to the sheet transport device configured in this way, when the user takes out the sheet from the discharging unit, even if the rotating unit is pushed by the sheet and rotates from the third position to the second position, When the seat comes into contact with the second stopper, the rotating portion is no longer pushed toward the second position. Therefore, it is possible to prevent the rotating portion from exceeding the second position and approaching the first position by the sheet taking-out operation, and it is possible to prevent the rotating portion from being unnecessarily rotated to the first position.

また、本開示のシート搬送装置において、排出部には、排出部におけるシートの支持面よりも下方へ凹む凹部が設けられ、回動部は、少なくとも第三位置へと回動した際に、回動部の一端が凹部に入り込む位置に配置され、凹部内には、第三位置へと回動した回動部に当接することにより、回動部を第三位置に位置決めする位置決め部が設けられていてもよい。 Further, in the sheet transport device of the present disclosure, the discharge portion is provided with a recess recessed downward from the support surface of the sheet in the discharge portion, and the rotating portion rotates when it is rotated to at least the third position.

Further, in the sheet transport device of the present disclosure, the slide portion has a position where the downstream end portion of the slide portion in the discharge direction of the sheet is at least at the same height as the upstream end portion of the rotating portion in the discharge direction of the sheet. It may be provided at the above height position.

このように構成されたシート搬送装置によれば、スライド部の端部が、少なくとも第三位置にある回動部の端部以上の高い位置にあるので、スライド部の端部を通過するシートの先端が、回動部の端部に引っ掛かるのを抑制することができる。 According to the sheet transport device configured in this way, since the end portion of the slide portion is at a position higher than the end portion of the rotating portion at least in the third position, the sheet passing through the end portion of the slide portion It is possible to prevent the tip from being caught by the end of the rotating portion.

また、本開示のシート搬送装置において、スライド部において、排出部へと排出されるシートに接触し得る箇所には、上向きに突出する複数のリブが形成されていてもよい。
このように構成されたシート搬送装置によれば、シートがリブによって案内されるため、スライド部とシートとの接触面積を少なくし、シートをスムーズに排出できる。 Further, in the sheet transport device of the present disclosure, a plurality of ribs protruding upward may be formed at a position where the slide portion can come into contact with the sheet discharged to the discharge portion.
According to the sheet transport device configured in this way, since the sheet is guided by the ribs, the contact area between the slide portion and the sheet can be reduced, and the sheet can be smoothly discharged.

また、本開示のシート搬送装置において、排出部には、回動部が第三位置にある場合に、付勢部によって付勢されたスライド部に当接して、スライド部から作用する押圧力を受ける受け部が設けられていてもよい。 Further, in the sheet transport device of the present disclosure, when the rotating portion is in the third position, the discharging portion abuts on the slide portion urged by the urging portion and exerts a pressing force acting from the slide portion. A receiving portion may be provided.

このように構成されたシート搬送装置によれば、第三位置にある回動部に不要な負荷がかかることを抑制できる。
また、本開示のシート搬送装置において、回動部が第二位置から第一位置までの範囲内に回動するのを規制する規制位置、及び回動部が第二位置から第一位置までの範囲内に回動するのを規制しない非規制位置へ変位可能な規制部材を備えてもよい。 According to the sheet transfer device configured in this way, it is possible to prevent an unnecessary load from being applied to the rotating portion at the third position.
Further, in the sheet transport device of the present disclosure, the regulated position that regulates the rotation of the rotating portion within the range from the second position to the first position, and the rotating portion from the second position to the first position. A regulatory member that can be displaced to an unregulated position that does not restrict rotation within the range may be provided.
