Description of the Related Art A paper processing apparatus that holds a booklet, conveys it, and enters a cutting unit is known (for example, Patent Document 1).

特開２００５−８９０２２号公報JP 2005-89022 A

しかしながら、従来の用紙処理装置では、断裁部に冊子を良好に進入させることができない場合があった。
以下、従来の用紙処理装置の問題点について、図９、図１０を参照して説明する。
挟持搬送部１００１は、冊子Ｄの背表紙側を挟持し、背表紙に対向する冊子Ｄの端部（小口端部）を断裁部１００２側に向けて搬送する。この場合、断裁部１００２は、断裁部１００２の内側に進入した冊子Ｄの小口端部に断裁刃を当接させて断裁を行う。
しかしながら、図９に示すように、冊子Ｄの表紙等が小口端部側に向かって末広がり状となり、小口端部が断裁部１００２への進入口に収まらない状態となってしまい、断裁部１００２に冊子Ｄを良好に進入させることができなくなる場合があった。 However, in the conventional paper processing apparatus, there are cases where the booklet cannot be satisfactorily entered into the cutting section.
Hereinafter, problems of the conventional sheet processing apparatus will be described with reference to FIGS.
The nipping / conveying unit 1001 nipping the back cover side of the booklet D, and conveys the end (small end) of the booklet D facing the back cover toward the cutting unit 1002 side. In this case, the cutting unit 1002 performs cutting by bringing a cutting blade into contact with the fore edge of the booklet D that has entered the inside of the cutting unit 1002.
However, as shown in FIG. 9, the cover or the like of the booklet D becomes divergent toward the edge of the edge, and the edge of the edge does not fit in the entrance to the cutting part 1002. In some cases, the booklet D cannot be satisfactorily entered.

また、仮に運よく断裁部１００２に冊子Ｄの端部が収まったとしても、図１０に示すように、冊子Ｄが末広がりを生じた状態で断裁部１００２に進入したことにより冊子Ｄの折り目を挟んで二股となった各冊子面が取る経路が不統一となってしまい、その状態で断裁部１００２により断裁された後の小口端部側が揃わなくなることがあった。   Also, even if the end of the booklet D fits into the cutting unit 1002 fortunately, as shown in FIG. 10, the booklet D enters the cutting unit 1002 in a state where the end of the booklet D is widened, so that the fold of the booklet D is sandwiched. Thus, the path taken by each bifurcated booklet surface becomes uneven, and the edge end side after cutting by the cutting unit 1002 may not be aligned in that state.

一方、単に挟持搬送部１００１による冊子Ｄの挟持面積を大きくして冊子Ｄの小口端部側を挟持面に沿わせようとしたとした場合、挟持に伴う動作部分が大きくなることから、用紙処理装置内の限られた空間で挟持のための動作を行わせることが困難となる。具体的には、挟持部材の形状を、用紙処理装置内の各部と衝突しない形状に加工する必要があり、設計や製造工程が煩雑なものとなる。   On the other hand, if the holding area of the booklet D by the holding and conveying unit 1001 is simply increased and the small edge end side of the booklet D is intended to be along the holding surface, the operation portion accompanying the holding increases, so that the paper processing It becomes difficult to perform an operation for clamping in a limited space in the apparatus. Specifically, it is necessary to process the clamping member into a shape that does not collide with each part in the sheet processing apparatus, which complicates the design and manufacturing process.

図２は、用紙処理装置３００の斜視図である。
図３は、用紙処理装置３００の内部に設けられた挟持搬送部３４０及び断裁部３７０を図２に示す矢印Ｖ１方向から見た側面図である。
図２、図３は、説明の便宜上、用紙処理装置３００の内部の構成を可視可能に図示しているが、実際には用紙処理装置３００の筐体を覆うよう設けられた外装の内側に設けられている。 Hereinafter, the configuration of the nipping and conveying unit 340 among the components of the sheet processing apparatus 300 will be described in detail.
FIG. 2 is a perspective view of the sheet processing apparatus 300.
FIG. 3 is a side view of the nipping / conveying unit 340 and the cutting unit 370 provided in the sheet processing apparatus 300 as viewed from the direction of the arrow V1 shown in FIG.
2 and 3 illustrate the internal configuration of the paper processing apparatus 300 in a visible manner for convenience of explanation, but in actuality, it is provided inside the exterior provided to cover the casing of the paper processing apparatus 300. It has been.

図２、図３に示すように、挟持搬送部３４０は、断裁部３７０の上方に設けられている。挟持搬送部３４０は、受け渡し部３６０により、図３の矢印Ｖ２に示すように後方から受け渡された中綴じ冊子Ｂを挟持する。そして、挟持搬送部３４０は、Ｚ方向に沿って設けられたガイドレールＬに沿って下降させるように中綴じ冊子Ｂを搬送し、中綴じ冊子Ｂの小口端部側を断裁部３７０に進入させる。   As shown in FIGS. 2 and 3, the nipping and conveying unit 340 is provided above the cutting unit 370. The sandwiching and conveying unit 340 sandwiches the saddle-stitched booklet B delivered from behind as shown by an arrow V2 in FIG. Then, the nipping and conveying unit 340 conveys the saddle-stitched booklet B so as to be lowered along the guide rail L provided along the Z direction, and causes the edge end side of the saddle-stitched booklet B to enter the cutting unit 370. .

図２、３に示すように、二つの挟持部材３４１、３４２は、例えば、Ｘ−Ｙ平面に沿う板状の部材であり、互いに対向する側の側面（挟持面）で中綴じ冊子Ｂを挟持する。ここで、挟持面は、Ｙ−Ｚ平面に沿う。
より具体的には、二つの挟持部材３４１、３４２は、搬送ユニットＵ内に設けられ、Ｘ−Ｙ平面について同一平面上に設けられた部材である。一方の挟持部材３４１は、搬送ユニットＵ内でＸ方向に沿って移動可能に設けられている。他方の挟持部材３４２は、搬送ユニットＵ内に固定されている。中綴じ冊子Ｂを挟持するに際して、挟持搬送部３４０は、一方の挟持部材３４１と他方の挟持部材３４２との間に中綴じ冊子Ｂを位置させた状態で一方の挟持部材３４１を他方の挟持部材３４２に近接させるように動作させることにより中綴じ冊子Ｂを挟持する。即ち、挟持搬送部３４０は、挟持される中綴じ冊子Ｂ等の用紙を挟んで設けられた二つの挟持部材３４１、３４２を有し、一方の挟持部材３４１を他方の挟持部材３４２に近接させるよう動作させることで用紙を挟持する。
ここで、二つの挟持部材３４１、３４２は、中綴じ冊子Ｂの背表紙側、即ち、中綴じ冊子Ｂを構成する用紙の折り目側で中綴じ冊子Ｂを挟持する挟持手段として機能する。 As shown in FIGS. 2 and 3, the two clamping members 341 and 342 are, for example, plate-like members along the XY plane, and sandwich the saddle-stitched booklet B on side surfaces (clamping surfaces) facing each other. To do. Here, the clamping surface is along the YZ plane.
More specifically, the two holding members 341 and 342 are members provided in the transport unit U and provided on the same plane with respect to the XY plane. One clamping member 341 is provided in the transport unit U so as to be movable along the X direction. The other clamping member 342 is fixed in the transport unit U. When sandwiching the saddle-stitched booklet B, the sandwiching and transporting unit 340 holds the one sandwiching member 341 in the state where the saddle-stitched booklet B is positioned between the one sandwiching member 341 and the other sandwiching member 342. The saddle-stitched booklet B is pinched by operating it so as to be close to 342. That is, the sandwiching and transporting unit 340 includes two sandwiching members 341 and 342 provided so as to sandwich a sheet such as the saddle-stitched booklet B to be sandwiched, and one sandwiching member 341 is brought close to the other sandwiching member 342. The paper is pinched by operating.
Here, the two clamping members 341 and 342 function as clamping means for clamping the saddle-stitched booklet B on the back cover side of the saddle-stitched booklet B, that is, on the fold side of the paper constituting the saddle-stitched booklet B.

なお、図示しないが、受け渡し部３６０は、例えば、紙面がＹ−Ｚ平面に沿う中綴じ冊子Ｂの背表紙側のＹ方向の両端を上側として担持し、中綴じ冊子Ｂの小口端部側を吊り下げるようにしてガイドレールＬの後方から前方に向かって搬送し、搬送ユニットＵと断裁部３７０との間に位置させる。その状態で、搬送駆動部３４４（図５参照）の動作に応じて搬送ユニットＵが下降することにより、二つの挟持部材３４１、３４２は、受け渡し部３６０に吊り下げられた中綴じ冊子Ｂの背表紙側を間に挟んで挟持可能な位置に位置決めされる。そして、一方の挟持部材３４１が他方の挟持部材３４２に対して近接するよう移動することにより、中綴じ冊子Ｂが挟持される。二つの挟持部材３４１、３４２による中綴じ冊子Ｂの挟持後、受け渡し部３６０は後方に退避する。   Although not shown in the drawings, the delivery unit 360 carries, for example, both ends in the Y direction on the spine cover side of the saddle-stitched booklet B along the YZ plane as the upper side, and the small edge end side of the saddle-stitched booklet B is used as the upper side. It is conveyed from the rear to the front of the guide rail L so as to be suspended, and is positioned between the conveyance unit U and the cutting part 370. In this state, the conveyance unit U is lowered according to the operation of the conveyance drive unit 344 (see FIG. 5), so that the two clamping members 341 and 342 are back of the saddle-stitched booklet B suspended from the transfer unit 360. It is positioned at a position where the cover side can be sandwiched. Then, the saddle-stitched booklet B is clamped by moving the one clamping member 341 so as to approach the other clamping member 342. After the saddle stitch booklet B is sandwiched by the two sandwiching members 341 and 342, the delivery unit 360 is retracted rearward.

次に、延出部材３４３について説明する。
図３に示すように、延出部材３４３は、例えば、一方の挟持部材３４１から下方、即ち、中綴じ冊子Ｂの小口端部側に延出して中綴じ冊子Ｂの片側の表紙面と当接し、中綴じ冊子Ｂを二つの挟持部材３４１、３４２の挟持面（Ｙ−Ｚ平面）に沿わせるように中綴じ冊子Ｂの片側の表紙面を支持する。延出部材３４３による中綴じ冊子Ｂの支持によって、図３に示すように、中綴じ冊子Ｂの小口端部側がＸ方向について末広がりになることを防止することができる。 Next, the extending member 343 will be described.
As shown in FIG. 3, the extending member 343 extends, for example, downward from one of the holding members 341, that is, to the small edge end side of the saddle-stitched booklet B, and comes into contact with the cover page on one side of the saddle-stitched booklet B. The cover surface on one side of the saddle-stitched booklet B is supported so that the saddle-stitched booklet B follows the holding surfaces (YZ planes) of the two holding members 341 and 342. By supporting the saddle-stitched booklet B by the extending member 343, it is possible to prevent the edge end side of the saddle-stitched booklet B from spreading in the X direction as shown in FIG.

図４は、挟持部材３４１及び延出部材３４３の一例を示す図である。
延出部材３４３は、例えば、挟持部材３４１に対して回動することで小口端部側に延出するよう設けられている。 FIG. 4 is a diagram illustrating an example of the clamping member 341 and the extending member 343.
For example, the extending member 343 is provided so as to extend to the edge end side by rotating with respect to the clamping member 341.

具体的には、例えば、図４に示すように、延出部材３４３は、棒状の部材であり、その一端が挟持部材３４１のＹ方向の端部側に設けられた回動軸３４３ａを中心に回動可能に支持され、他端側が挟持部材３４１のＹ方向の中心側に向かって設けられている。ここで、延出部材３４３の回動軸はＸ方向に沿うよう設けられており、延出部材３４３は、Ｙ−Ｚ平面に沿って回動する。
また、図４に示すように、延出部材３４３は、二つ設けられ、二つの延出部材３４３の各々の回動軸３４３ａが挟持部材３４１のＹ方向の両端側に設けられている。二つの延出部材３４３は、図４の位置Ｐ１に示すように、挟持部材３４１から延出されず、回動軸３４３ａから他端側に沿う長手方向がＹ方向に沿う回動角度で支持される場合、Ｙ方向について一直線上となり、互いの他端がＹ方向について対向する位置となるよう設けられている。 Specifically, for example, as shown in FIG. 4, the extending member 343 is a rod-shaped member, and one end of the extending member 343 is centered on a rotating shaft 343 a provided on the end side in the Y direction of the holding member 341. The other end side is supported toward the center of the holding member 341 in the Y direction. Here, the rotation shaft of the extending member 343 is provided along the X direction, and the extending member 343 rotates along the YZ plane.
As shown in FIG. 4, two extending members 343 are provided, and the rotation shafts 343 a of the two extending members 343 are provided on both ends of the holding member 341 in the Y direction. As shown at position P1 in FIG. 4, the two extending members 343 are not extended from the clamping member 341, and the longitudinal direction along the other end side from the rotating shaft 343a is supported at a rotation angle along the Y direction. In this case, the other ends are arranged in a straight line with respect to the Y direction, and the other ends of the Y direction are opposed to each other.

延出部材３４３は、回動軸３４３ａを介して回動駆動部３４５（図５参照）と連結されており、回動駆動部３４５の動作に応じて回動する。回動駆動部３４５は、例えば、電動機等のモーターである。   The extending member 343 is connected to a rotation drive unit 345 (see FIG. 5) via a rotation shaft 343a, and rotates according to the operation of the rotation drive unit 345. The rotation drive unit 345 is, for example, a motor such as an electric motor.

延出部材３４３は、挟持部材３４１、３４２により挟持された中綴じ冊子Ｂ等の用紙の小口端部側に向かって、挟持部材３４１から他端側が延出した位置（例えば、図４に示す位置Ｐ２等）となる回動角度と、挟持部材３４１から他端側が延出しない位置（例えば、図４に示す位置Ｐ１等）となる回動角度との間で回動する。
延出部材３４３は、挟持部材３４１、３４２による中綴じ冊子Ｂの挟持に際して挟持部材３４１から延出するように回動し、中綴じ冊子Ｂの小口端部側と当接することにより当該小口端部側を下方に向けるよう案内する。
ここで、延出部材３４３は、挟持部材３４１、３４２により挟持された中綴じ冊子Ｂ等の中折り用紙の小口端部側の表紙面の片側に当接して当該小口端部側を断裁部３７０に案内する案内手段として機能する。 The extending member 343 extends from the holding member 341 at the other end side toward the edge end side of the paper such as the saddle-stitched booklet B held by the holding members 341 and 342 (for example, the position shown in FIG. 4). P2 or the like, and a rotation angle at which the other end side does not extend from the clamping member 341 (for example, the position P1 or the like shown in FIG. 4).
The extending member 343 rotates so as to extend from the pinching member 341 when the saddle-stitched booklet B is pinched by the pinching members 341 and 342, and comes into contact with the small-edge end side of the saddle-stitched booklet B, thereby Guide them to face down.
Here, the extending member 343 comes into contact with one side of the front cover surface of the small edge end side of the middle folded paper such as the saddle stitch booklet B held by the holding members 341 and 342, and the edge end side is cut to the cutting portion 370. It functions as a guide means for guiding to.

また、図４の位置Ｐ２に示すような、挟持部材３４１から他端側が延出した位置となる回動角度における延出部材３４３の延出量は、断裁部３７０の各構成との位置関係に応じる。   Further, the extension amount of the extending member 343 at the rotation angle at which the other end side extends from the clamping member 341 as shown in the position P2 in FIG. 4 is in a positional relationship with each component of the cutting portion 370. Respond.

延出部材３４３の延出量に係る説明に先立ち、断裁部３７０の主要構成及びその動作について説明する。
断裁部３７０は、Ｘ−Ｙ平面に沿うよう設けられて、刃の先端が後方に向いた断裁刃３７１と、断裁刃３７１の上方に設けられて中綴じ冊子Ｂの小口端部付近を挟持する断裁挟持部３７２、３７３と、を有する。断裁刃３７１、断裁挟持部３７３はそれぞれＸ方向に沿って移動可能に設けられている。
断裁部３７０は、断裁挟持部３７２の動作により、断裁挟持部３７２、３７３が協働して中綴じ冊子Ｂの小口端部付近（例えば、図４に示す範囲Ｑ１）を挟持する。さらに、その状態で、断裁刃３７１が動作することにより、中綴じ冊子Ｂの端部（例えば、図４に示す範囲Ｑ２）を切り落とす。 Prior to the description of the extension amount of the extension member 343, the main configuration and operation of the cutting unit 370 will be described.
The cutting part 370 is provided along the XY plane, and is provided above the cutting blade 371 with the cutting edge 371 having the blade tip directed rearward, and sandwiches the vicinity of the small edge of the saddle-stitched booklet B. And cutting and clamping portions 372 and 373. The cutting blade 371 and the cutting clamping part 373 are each provided so as to be movable along the X direction.
By the operation of the cutting and clamping unit 372, the cutting unit 370 holds the vicinity of the edge of the saddle stitch booklet B (for example, a range Q1 shown in FIG. 4) in cooperation with the cutting and clamping units 372 and 373. Further, in this state, the cutting blade 371 operates to cut off an end portion of the saddle stitch booklet B (for example, a range Q2 shown in FIG. 4).

即ち、図４に示す中綴じ冊子Ｂの範囲Ｑ１より下方は、断裁部３７０の断裁挟持部３７２、３７３や断裁刃３７１が中綴じ冊子Ｂに当接する範囲に対応するため、仮にこの位置まで延出部材３４３が延出している場合、延出部材３４３と断裁部３７０の構成とが当接してしまい、断裁部３７０の動作を妨げる可能性がある。   In other words, the area below the range Q1 of the saddle-stitched booklet B shown in FIG. 4 corresponds to the range in which the cutting and clamping parts 372 and 373 of the cutting part 370 and the cutting blade 371 are in contact with the saddle-stitched booklet B. When the protruding member 343 extends, the extending member 343 and the configuration of the cutting portion 370 may come into contact with each other, which may hinder the operation of the cutting portion 370.

そこで、本実施形態では、図４の位置Ｐ２に示すように、挟持部材３４１から延出した延出部材３４３の他端側の端部の位置が、中綴じ冊子Ｂの小口端部側において断裁部３７０の構成が当接する範囲（範囲Ｑ１、Ｑ２）よりも上方となるように設けられている。
具体的には、延出部材３４３は、例えば、挟持部材３４１から延出した他端側の端部の位置が、範囲Ｑ２の上端に対して所定のマージンＭを隔てた位置Ｐ２となるよう位置決めされる。即ち、延出部材３４３の延出量は、中綴じ冊子Ｂの背表紙の折り目と小口端部との間の長さＱのうち、背表紙から挟持部材３４１により挟持された範囲の下端までの範囲Ｑ０、小口端部側の範囲Ｑ１、範囲Ｑ２及び所定のマージンＭを差し引いた長さに応じる。 Therefore, in the present embodiment, as shown at a position P2 in FIG. 4, the position of the end portion on the other end side of the extending member 343 extending from the clamping member 341 is cut on the edge end side of the saddle stitch booklet B. The configuration of the portion 370 is provided so as to be higher than the range (range Q1, Q2) in contact.
Specifically, the extending member 343 is positioned so that, for example, the position of the end portion on the other end side extending from the clamping member 341 is a position P2 that is separated from the upper end of the range Q2 by a predetermined margin M. Is done. That is, the extending amount of the extending member 343 is from the back cover to the lower end of the range clamped by the clamping member 341 in the length Q between the fold of the spine of the saddle stitch booklet B and the edge of the fore edge. It corresponds to the length obtained by subtracting the range Q0, the range Q1, the range Q2 on the fore edge side, and the predetermined margin M.

ここで、中綴じ冊子Ｂの背表紙の折り目と小口端部との間の長さＱは、中綴じ冊子Ｂの作成に用いられた用紙のサイズ等に応じて変化する。また、切り落とされる中綴じ冊子Ｂの端部の幅（例えば、図４に示す範囲Ｑ２）も任意に設定可能である。これらのように、中綴じ冊子の断裁及び挟持に係る各種の範囲は変更されうるものであることから、延出部材３４３の延出量は、変化しうる中綴じ冊子Ｂのサイズや切り落とされる端部の幅に応じて制御される。   Here, the length Q between the fold of the spine of the saddle stitch booklet B and the edge of the fore edge varies depending on the size of the paper used to create the saddle stitch booklet B. Moreover, the width (for example, range Q2 shown in FIG. 4) of the edge part of the saddle-stitched booklet B to be cut off can be arbitrarily set. As described above, since various ranges related to the cutting and clamping of the saddle-stitched booklet can be changed, the extension amount of the extending member 343 can change the size of the saddle-stitched booklet B that can be changed or the edge to be cut off. It is controlled according to the width of the part.

本実施形態では、延出部材３４３は、挟持部材３４１、３４２による中綴じ冊子Ｂの挟持が完了する前に小口端部側に延出される。   In the present embodiment, the extending member 343 is extended to the edge end side before the holding of the saddle stitch booklet B by the holding members 341 and 342 is completed.

また、図２〜図４に示すように、二つの挟持部材３４１、３４２のうち他方の挟持部材３４２側には、ガイドワイヤー３５０が設けられている。
ガイドワイヤー３５０は、挟持部材３４２からＺ方向に沿って下方に延設されたワイヤーである。
ガイドワイヤー３５０は、例えば、図４に示すように、挟持部材３４１、３４２により挟持された中綴じ冊子のＹ方向の中央に対してほぼ均等な距離となるように二本設けられる。当該二本のガイドワイヤー３５０、３５０は共にＺ方向に沿い、互いに平行となる。
また、各ガイドワイヤー３５０のＹ方向の位置は、二つの挟持部材３４１、３４２に挟持される中綴じ冊子Ｂのうち、Ｙ方向のサイズが最小である中綴じ冊子ＢのＹ方向の両端の内側となるよう設けられている。
また、ガイドワイヤー３５０は、図３に示すように、Ｘ方向について、二つの挟持部材３４１、３４２の他方の挟持部材３４２の挟持面の位置に対応するよう設けられる。 As shown in FIGS. 2 to 4, a guide wire 350 is provided on the other clamping member 342 side of the two clamping members 341 and 342.
The guide wire 350 is a wire that extends downward from the clamping member 342 along the Z direction.
For example, as shown in FIG. 4, two guide wires 350 are provided so as to have a substantially equal distance with respect to the center in the Y direction of the saddle stitch booklet held by the holding members 341 and 342. The two guide wires 350 and 350 are both parallel to each other along the Z direction.
The position of each guide wire 350 in the Y direction is the inner side of both ends in the Y direction of the saddle-stitched booklet B having the smallest size in the Y-direction among the saddle-stitched booklets B sandwiched between the two holding members 341 and 342. It is provided to become.
Further, as shown in FIG. 3, the guide wire 350 is provided so as to correspond to the position of the holding surface of the other holding member 342 of the two holding members 341 and 342 in the X direction.

Ｘ、Ｙ、Ｚ方向について上記のように設けられるガイドワイヤー３５０は、図３に示すように、背表紙側が二つの挟持部材３４１、３４２により挟持された中綴じ冊子Ｂのうち、他方の挟持部材３４２の小口端部側と当接して当該小口端部側のＸ方向における末広がりを防止する。即ち、ガイドワイヤー３５０は、他方の挟持部材３４２の挟持面に沿うよう設けられて当該二つの挟持部材３４１、３４２により挟持された中綴じ冊子Ｂの他方側の小口端部側を当該二つの挟持部材の挟持面に沿わせるように中綴じ冊子Ｂを支持する延設部材として機能する。また、ガイドワイヤー３５０は、挟持部材３４１、３４２により挟持された中綴じ冊子Ｂ等の中折り用紙の小口端部側の表紙面のうち、延出部材３４３により案内されない側に当接して当該小口端部側を断裁部３７０に案内する案内手段として機能する。   As shown in FIG. 3, the guide wire 350 provided as described above in the X, Y, and Z directions is the other holding member of the saddle-stitched booklet B whose back cover side is held by two holding members 341 and 342. It abuts against the fore edge end side of 342 to prevent the diverging in the X direction on the fore edge end side. In other words, the guide wire 350 is provided along the holding surface of the other holding member 342, and the other end of the saddle-stitched booklet B held by the two holding members 341 and 342 is held between the two holding pins. It functions as an extending member that supports the saddle-stitched booklet B so as to be along the clamping surface of the member. In addition, the guide wire 350 is in contact with a side of the front cover surface of the center folded end of the saddle-stitched booklet B or the like that is sandwiched between the sandwiching members 341 and 342 and is not guided by the extending member 343, so It functions as a guiding means for guiding the end side to the cutting section 370.

また、ガイドワイヤー３５０は、連動機構３５１により搬送ユニットＵの上下動と連動するように移動する。
具体的には、例えば、ガイドワイヤー３５０は、図３に示すように、挟持部材３４２の下方に延設された側が、断裁部３７０の手前に設けられた定滑車３５１ａにより前方に導かれ、さらに当該前方に設けられた上方に導かれている。そして、ガイドワイヤー３５０の上方に導かれた端部側は、固定板３５１ｂを介して搬送ベルト３４６に連結固定されている。 Further, the guide wire 350 moves so as to be interlocked with the vertical movement of the transport unit U by the interlocking mechanism 351.
Specifically, for example, as shown in FIG. 3, the guide wire 350 is guided forward by a fixed pulley 351 a provided on the front side of the cutting portion 370 on the side extended below the clamping member 342. It is led upward provided in the front. The end side guided above the guide wire 350 is connected and fixed to the transport belt 346 via a fixing plate 351b.

搬送ベルト３４６は、図３に示すように、上下に設けられた二つのローラー３４６ａ、３４６ｂにより担持されることでＺ方向に延設されている。また、搬送ベルト３４６には、図３に示すように、搬送ユニットＵが固定されている。
ここで、搬送ベルト３４６は、二つのローラー３４６ａ、３４６ｂにより担持されることにより、図３に示すように、Ｚ方向に沿った二つの平面部を形成しているが、搬送ユニットＵが固定されている側と固定板３５１ｂとが設けられている側は、互いに異なる平面部である。即ち、搬送ベルト３４６の駆動により搬送ユニットＵ、固定板３５１ｂのいずれか一方がＺ方向に沿って下降した場合、他方が上昇するこことなる。 As shown in FIG. 3, the transport belt 346 is extended in the Z direction by being supported by two rollers 346 a and 346 b provided on the upper and lower sides. Further, as shown in FIG. 3, a transport unit U is fixed to the transport belt 346.
Here, the transport belt 346 is supported by two rollers 346a and 346b to form two flat portions along the Z direction as shown in FIG. 3, but the transport unit U is fixed. The side where the fixing plate 351b is provided and the side where the fixing plate 351b is provided are different flat portions. That is, when one of the transport unit U and the fixed plate 351b is lowered along the Z direction by driving the transport belt 346, the other is lifted.

また、二つのローラー３４６ａ、３４６ｂの一方は、搬送駆動部３４４に連結されている。搬送駆動部３４４は、例えば、電動機等のモーターであり、二つのローラー３４６ａ、３４６ｂの一方を回転させるよう動作することにより搬送ベルト３４６を駆動する。搬送ベルト３４６の駆動に応じて、搬送ユニットＵは上下動し、挟持部材３４１、３４２により挟持された中綴じ冊子Ｂを搬送する。
このとき、搬送ユニットＵの上下動に応じて、挟持部材３４２から下方に延設されたガイドワイヤー３５０も上下動方向に付勢されることとなるが、上記のように、固定板３５１ｂに固定されたガイドワイヤー３５０の端部側は、搬送ユニットＵの上下動と逆方向に動作する側の搬送ベルト３４６の平面に固定されているので、当該端部側が搬送ユニットＵに対して逆方向に移動することにより、挟持部材３４２から固定板３５１ｂまでの間におけるガイドワイヤー３５０の張力が保持される。このように、ガイドワイヤー３５０は、定滑車３５１ａや固定板３５１ｂ等を備える連動機構３５１により、搬送ユニットＵの移動に連動する。 One of the two rollers 346 a and 346 b is connected to the transport driving unit 344. The conveyance driving unit 344 is, for example, a motor such as an electric motor, and drives the conveyance belt 346 by operating to rotate one of the two rollers 346a and 346b. The transport unit U moves up and down according to the driving of the transport belt 346 and transports the saddle stitch booklet B sandwiched by the sandwiching members 341 and 342.
At this time, according to the vertical movement of the transport unit U, the guide wire 350 extending downward from the holding member 342 is also urged in the vertical movement direction, but is fixed to the fixing plate 351b as described above. The end side of the guide wire 350 is fixed to the plane of the transport belt 346 on the side that operates in the direction opposite to the vertical movement of the transport unit U. By moving, the tension of the guide wire 350 between the clamping member 342 and the fixed plate 351b is maintained. As described above, the guide wire 350 is interlocked with the movement of the transport unit U by the interlocking mechanism 351 including the fixed pulley 351a and the fixed plate 351b.

ここで、搬送駆動部３４４は、搬送ユニットＵを移動させることで、挟持部材３４１、３４２により挟持された中綴じ冊子Ｂ等の中折り用紙の小口端部側を断裁刃３７１が設けられた位置に進入させるよう挟持部材３４１、３４２を移動させる移動手段として機能する。
また、連動機構３５１は、搬送駆動部３４４による挟持部材の移動に連動してガイドワイヤー３５０を挟持部材３４２の移動方向に沿って移動させる連動手段として機能する。 Here, the transport driving unit 344 moves the transport unit U, so that the cutting edge 371 is provided on the edge end side of the half-folded sheet such as the saddle-stitched booklet B sandwiched by the sandwiching members 341 and 342. It functions as a moving means for moving the holding members 341 and 342 so as to enter.
The interlocking mechanism 351 functions as interlocking means that moves the guide wire 350 along the moving direction of the sandwiching member 342 in conjunction with the movement of the sandwiching member by the transport driving unit 344.

以下、挟持部材３４１、３４２により挟持された中綴じ冊子Ｂの搬送及び断裁の進行についてその概要を説明する。
受け渡し部３６０から受け渡された中綴じ冊子Ｂの背表紙側を挟持した挟持部材３４１、３４２は、搬送駆動部３４４の動作により搬送ユニットＵがガイドレールＬに沿って下降することにより、中綴じ冊子Ｂを挟持した状態で断裁部３７０に向かって下降する。このとき、中綴じ冊子Ｂの小口端部側は、一方の挟持部材３４１側が延出部材３４３により支持され、他方の挟持部材３４２側がガイドワイヤー３５０により支持されることにより、Ｘ方向について末広がりを生じさせることがない状態で案内されながら下降する。 Hereinafter, an outline of the conveyance and cutting progress of the saddle-stitched booklet B sandwiched by the sandwiching members 341 and 342 will be described.
The holding members 341 and 342 that hold the back cover side of the saddle-stitched booklet B delivered from the delivery unit 360 are saddle-stitched by the conveyance unit U being lowered along the guide rail L by the operation of the conveyance drive unit 344. The booklet B is lowered toward the cutting unit 370 with the booklet B being sandwiched. At this time, the edge portion side of the saddle-stitched booklet B is widened in the X direction by the one holding member 341 side being supported by the extending member 343 and the other holding member 342 side being supported by the guide wire 350. It descends while being guided in a state where it is not allowed.

また、搬送ユニットＵの下降に伴い、一方の挟持部材３４１から延出された延出部材３４３も同様に下降する。また、上記のように、連動機構３５１により、他方の挟持部材３４２から下方に延設されて中綴じ冊子Ｂの小口端部側を支持する部分のガイドワイヤー３５０も連動して下降する。   In addition, as the transport unit U is lowered, the extending member 343 extended from the one clamping member 341 is similarly lowered. In addition, as described above, the interlocking mechanism 351 also lowers the guide wire 350 of the portion that extends downward from the other pinching member 342 and supports the edge end side of the saddle stitch booklet B in conjunction with it.

小口端部側が支持された中綴じ冊子Ｂは、搬送ユニットＵの下降により、断裁部３７０の断裁挟持部３７２、３７３の間の隙間に小口端部側を進入させる。
ここで、図３に示すように、断裁部３７０の断裁挟持部３７２の上方に、中綴じ冊子Ｂの小口端部側の進入をガイドする進入ガイド部材３７４を設けるようにしてもよい。進入ガイド部材３７４は、例えば、断裁挟持部３７２、３７３のうち後方に位置する断裁挟持部３７２の配設位置から上方にかけてＸ方向について後方に末広がり状となる傾斜面を有する。当該傾斜面は、断裁挟持部３７２、３７３の間の隙間に連続しており、当該傾斜面により中綴じ冊子Ｂの進入をガイドする。
また、進入ガイド部材３７４は、中綴じ冊子が断裁挟持部３７２、３７３の間の隙間に進入した後、図３に示す後方への回動等の動作により収納されるようにしてもよい。 The saddle-stitched booklet B on which the edge end side is supported causes the edge edge side to enter the gap between the cutting and clamping parts 372 and 373 of the cutting part 370 when the transport unit U is lowered.
Here, as shown in FIG. 3, an entry guide member 374 that guides the entry of the saddle stitch booklet B on the edge end side may be provided above the cutting nipping part 372 of the cutting part 370. The approach guide member 374 has, for example, an inclined surface that is divergent in the rearward direction with respect to the X direction from the position where the cutting and clamping portion 372 located at the rear of the cutting and holding portions 372 and 373 is disposed upward. The inclined surface is continuous with the gap between the cutting and clamping portions 372 and 373, and guides the saddle stitch booklet B to enter by the inclined surface.
Further, the entry guide member 374 may be accommodated by an operation such as backward rotation shown in FIG. 3 after the saddle stitch booklet enters the gap between the cutting and clamping portions 372 and 373.

搬送駆動部３４４は、断裁部３７０により断裁される中綴じ冊子Ｂの端部（例えば、図４に示す範囲Ｑ２）が断裁部３７０の断裁刃３７１の切断位置より下方に延出する位置となるまで中綴じ冊子Ｂを下降させるように搬送ユニットＵを位置決めする。この状態で、断裁部３７０の断裁挟持部３７２、３７３が動作して中綴じ冊子Ｂの小口端部付近（例えば、図４に示す範囲Ｑ１）を挟持する。その後、断裁刃３７１が動作して中綴じ冊子Ｂの端部を切り落とす断裁処理を行う。
断裁処理後、断裁挟持部３７２、３７３が動作して、中綴じ冊子Ｂの挟持を解消する。その後、搬送駆動部３４４が動作し、挟持部材３４１、３４２による中綴じ冊子の挟持を維持した状態で搬送ユニットＵを上昇させる。延出部材３４３及びガイドワイヤー３５０も当該上昇に連動して移動する。
上昇により持ち上げられた中綴じ冊子Ｂは、挟持部材３４１、３４２による挟持を解消されて、排出部３８０を介して排出される。 The conveyance drive unit 344 is located at a position where an end portion (for example, a range Q2 shown in FIG. 4) of the saddle stitch booklet B cut by the cutting unit 370 extends downward from a cutting position of the cutting blade 371 of the cutting unit 370. The conveyance unit U is positioned so that the saddle stitch booklet B is lowered. In this state, the cutting and clamping units 372 and 373 of the cutting unit 370 operate to clamp the vicinity of the edge end portion of the saddle stitch booklet B (for example, the range Q1 shown in FIG. 4). Thereafter, the cutting blade 371 operates to perform a cutting process of cutting off the end portion of the saddle stitch booklet B.
After the cutting process, the cutting and clamping units 372 and 373 operate to cancel the saddle stitch booklet B. Thereafter, the transport driving unit 344 operates to raise the transport unit U in a state where the sandwiching booklet is held by the sandwiching members 341 and 342. The extending member 343 and the guide wire 350 also move in conjunction with the ascent.
The saddle-stitched booklet B lifted by the lift is released from the clamping unit 341 and 342 and discharged through the discharge unit 380.

なお、延出部材３４３の延出動作及び延出量の調節のための回動角度の制御、即ち、回動駆動部３４５の動作制御や、搬送ユニットＵの上下動に応じた搬送駆動部３４４の動作制御、挟持部材３４１を直動させる電動機等の挟持駆動部３４１ａ（図５参照）等の動作制御は、用紙処理装置３００の制御部である用紙処理制御部５０５による。   Note that the rotation of the extending member 343 and the rotation angle for adjusting the extension amount, that is, the operation control of the rotation driving unit 345 and the conveyance driving unit 344 corresponding to the vertical movement of the conveyance unit U are described. The operation control of the nipping drive unit 341a (see FIG. 5) such as an electric motor that linearly moves the nipping member 341 is performed by a sheet processing control unit 505 that is a control unit of the sheet processing apparatus 300.

図５は、画像形成システム１の動作制御に係る主要構成を示すブロック図である。

操作表示部５０１は、例えば、タッチパネル方式の操作表示装置や各種の入力のためのスイッチ、キー等を有し、ユーザーの入力内容に応じた信号を中央制御部５０２に送信する。
中央制御部５０２、画像形成制御部５０３、用紙反転制御部５０４、用紙処理制御部５０５及び平綴じ処理制御部５０６はそれぞれ、ＣＰＵ、ＲＡＭ、ＲＯＭ等を有し、処理内容に応じたソフトウェア・プログラムや各種のデータを読み出して実行処理する。 The operation display unit 501 includes, for example, a touch panel type operation display device, various input switches, keys, and the like, and transmits a signal corresponding to a user input content to the central control unit 502.
The central control unit 502, the image formation control unit 503, the paper reversal control unit 504, the paper processing control unit 505, and the side stitching processing control unit 506 each have a CPU, RAM, ROM, and the like, and a software program corresponding to the processing content And various data are read and executed.

中央制御部５０２は、操作表示部５０１を介して入力されたユーザーの入力内容に応じて、用紙のサイズや画像形成時の色数（例えば、カラー・グレースケール・モノクロ等）、中綴じされる一部の用紙の枚数、余白部分となる端部の断裁の実施／非実施、断裁される端部の幅等、画像形成システム１に係る各種の設定を行う。そして、中央制御部５０２は、画像形成制御部５０３、用紙反転制御部５０４、用紙処理制御部５０５及び平綴じ処理制御部５０６の各制御部に対して設定内容に応じた処理を施すための命令を出力する。各制御部は、命令に応じてそれぞれの制御対象である装置の動作を制御する。   The central control unit 502 performs saddle stitching on the paper size and the number of colors at the time of image formation (for example, color, grayscale, monochrome, etc.) according to the input content of the user input via the operation display unit 501. Various settings related to the image forming system 1 are made, such as the number of some sheets, the execution / non-execution of the cutting of the edge that is the margin, and the width of the edge to be cut. Then, the central control unit 502 instructs the control units of the image formation control unit 503, the paper reversal control unit 504, the paper processing control unit 505, and the side stitching processing control unit 506 to perform processing according to the set contents. Is output. Each control unit controls the operation of the device to be controlled according to the command.

以下、特に、用紙処理制御部５０５による用紙処理装置３００の断裁処理前後の動作制御について説明する。
まず、用紙処理制御部５０５は、受け渡し部３６０を後方から前方に移動させて、中綴じ冊子Ｂを搬送ユニットＵと断裁部３７０との間に位置させる。次に、用紙処理制御部５０５は、搬送駆動部３４４を動作させて搬送ユニットＵを下降させ、中綴じ冊子Ｂを二つの挟持部材３４１、３４２の間に位置させる。次に、用紙処理制御部５０５は、挟持駆動部３４１ａを動作させて一方の挟持部材３４１を前方に移動させると共に回動駆動部３４５を動作させて延出部材３４３を下方に延出させ、二つの挟持部材３４１、３４２による中綴じ冊子Ｂの挟持と延出部材３４３による中綴じ冊子Ｂの小口端部側の案内とを行う。ここで、回動駆動部３４５の動作による延出部材３４３の延出の完了は、二つの挟持部材３４１、３４２による中綴じ冊子Ｂの挟持の完了前に行われる。また、挟持駆動部３４１ａの動作開始前に、回動駆動部３４５の動作による延出部材３４３の延出を完了させるようにしてもよい。また、用紙処理制御部５０５は、中綴じ冊子Ｂのサイズに応じて変化する中綴じ冊子Ｂの背表紙と小口端部との間の長さや、断裁される小口端部の長さの変化等に応じて挟持部材３４１に対する延出部材３４３の延出量を調節するよう回動駆動部３４５の動作を制御する。
ここで、用紙処理制御部５０５は、延出部材３４３の延出量を調節する調節手段として機能する。 Hereinafter, in particular, operation control before and after the cutting process of the sheet processing apparatus 300 by the sheet processing control unit 505 will be described.
First, the sheet processing control unit 505 moves the transfer unit 360 from the rear to the front, and positions the saddle stitch booklet B between the transport unit U and the cutting unit 370. Next, the sheet processing control unit 505 operates the transport driving unit 344 to lower the transport unit U and position the saddle stitch booklet B between the two sandwiching members 341 and 342. Next, the sheet processing control unit 505 operates the clamping drive unit 341a to move one clamping member 341 forward and operates the rotation driving unit 345 to extend the extending member 343 downward. The saddle-stitched booklet B is clamped by the two clamping members 341 and 342 and the small edge end side of the saddle-stitched booklet B is guided by the extending member 343. Here, the completion of the extension of the extension member 343 by the operation of the rotation drive unit 345 is performed before the completion of the saddle stitch booklet B clamping by the two clamping members 341 and 342. In addition, the extension of the extension member 343 by the operation of the rotation drive unit 345 may be completed before the operation of the clamping drive unit 341a is started. Further, the sheet processing control unit 505 changes the length between the spine cover of the saddle-stitched booklet B and the edge edge of the saddle-stitched booklet B that changes according to the size of the saddle-stitched booklet B, changes in the length of the edge edge that is cut, and the like. Accordingly, the operation of the rotation drive unit 345 is controlled so as to adjust the extension amount of the extension member 343 with respect to the clamping member 341.
Here, the sheet processing control unit 505 functions as an adjusting unit that adjusts the extension amount of the extension member 343.

その後、用紙処理制御部５０５は、受け渡し部３６０を後方に退避させる。次に、用紙処理制御部５０５は、搬送駆動部３４４を動作させて搬送ユニットＵを下降させ、中綴じ冊子Ｂを断裁部３７０に進入させる。続いて、用紙処理制御部５０５は、断裁部３７０の断裁挟持部３７２、３７３による中綴じ冊子Ｂの小口端部付近の挟持、断裁刃３７１による断裁処理のための動作制御を順次行う。
その後、用紙処理制御部５０５は、断裁挟持部３７２、３７３による中綴じ冊子Ｂの挟持の解消、搬送駆動部３４４の動作による搬送ユニットＵの上昇、排出部３８０による中綴じ冊子Ｂの排出のための動作制御を順次行う。 Thereafter, the sheet processing control unit 505 retracts the transfer unit 360 backward. Next, the sheet processing control unit 505 operates the transport driving unit 344 to lower the transport unit U, and causes the saddle stitch booklet B to enter the cutting unit 370. Subsequently, the sheet processing control unit 505 sequentially performs operation control for holding the vicinity of the edge portion of the saddle-stitched booklet B by the cutting and holding units 372 and 373 of the cutting unit 370 and cutting processing by the cutting blade 371.
After that, the sheet processing control unit 505 eliminates the pinching of the saddle-stitched booklet B by the cutting and pinching units 372 and 373, raises the transport unit U by the operation of the transport driving unit 344, and discharges the saddle-stitched booklet B by the discharge unit 380. The operation control is sequentially performed.

以上、本実施形態の画像形成システム１によれば、挟持部材３４１、３４２により挟持された中綴じ冊子Ｂの小口端部側の表紙面の片側に延出可能に設けられた延出部材３４３が当該小口端部側の表紙面と当接して当該小口端部側を断裁部３７０に案内し、もう片側をガイドワイヤー３５０が案内するので、中綴じ冊子Ｂの小口端部側の末広がりを防止して中綴じ冊子Ｂの端部を断裁部３７０にスムースに進入させることができる。
また、末広がりが防止されることにより、中綴じ冊子Ｂの背表紙から両端部までの各々の紙面をほぼ同一方向に沿わせることができることから、端部の位置を揃えることができ、断裁処理後の冊子の縁をより美しく仕上げることができる。即ち、本実施形態の画像形成システム１によれば、中綴じ冊子Ｂの断裁精度（品位）がより向上する。
また、延出部材３４３は延出可能に設けられているので、挟持部材３４１から延出しない状態で収納されることにより挟持部材３４１の移動（例えば、前方への移動）により動作する部分の断面積（例えば、Ｙ−Ｚ平面の面積）を最小限とすることができ、用紙処理装置内の限られた空間で良好に末広がりを防止することができる。即ち、延出／非延出の切替により用紙処理装置３００内の各構成との衝突を避けられるので、挟持部材３４１の形状を用紙処理装置３００内の各構成に合わせるための設計や製造工程を必要とせず、より簡易な仕組みにより末広がりを防止することができる。 As described above, according to the image forming system 1 of the present embodiment, the extending member 343 provided so as to be able to extend on one side of the front cover surface of the saddle stitch booklet B sandwiched by the sandwiching members 341 and 342 is provided. Since the guide edge 350 is guided to the cutting edge 370 by abutting against the front cover surface of the edge edge side, and the guide wire 350 guides the other side, it is prevented from spreading on the edge edge side of the saddle stitch booklet B. Thus, the end portion of the saddle-stitched booklet B can smoothly enter the cutting portion 370.
Further, by preventing the spread of the end, it is possible to align the paper surfaces from the spine of the saddle-stitched booklet B to both ends in substantially the same direction. The edge of the booklet can be finished more beautifully. That is, according to the image forming system 1 of the present embodiment, the cutting accuracy (quality) of the saddle stitch booklet B is further improved.
In addition, since the extending member 343 is provided so as to be able to extend, the portion that is operated by the movement (for example, forward movement) of the clamping member 341 by being stored without being extended from the clamping member 341 is cut off. The area (for example, the area of the YZ plane) can be minimized, and the spread can be prevented well in a limited space in the sheet processing apparatus. In other words, since the collision with each component in the sheet processing apparatus 300 can be avoided by switching between extension / non-extension, the design and manufacturing process for matching the shape of the holding member 341 with each component in the sheet processing apparatus 300 is performed. It is not necessary, and spread can be prevented by a simpler mechanism.

また、延出部材３４３は、挟持部材３４１から延出するので、非延出時に延出部材３４３が挟持部材３４１に収納されることで中綴じ冊子Ｂの挟持に係る構成の挟持面積をより小さく収めることができ、受け渡し部３６０等の用紙処理装置３００内の各構成と挟持搬送部３４０との各部との衝突を生じさせることなく中綴じ冊子Ｂの挟持及び断裁部３７０への案内を行うことができる。   In addition, since the extending member 343 extends from the holding member 341, the extending member 343 is accommodated in the holding member 341 when not extended, so that the holding area of the configuration related to holding the saddle-stitched booklet B is further reduced. The saddle-stitched booklet B is sandwiched and guided to the cutting unit 370 without causing a collision between each component in the sheet processing apparatus 300 such as the transfer unit 360 and the nipping and conveying unit 340. Can do.

また、挟持部材３４１、３４２による中綴じ冊子Ｂの背表紙側の挟持が完了する前に延出部材３４３を中綴じ冊子Ｂの小口端部側に延出するので、延出部材３４３と中綴じ冊子Ｂの表紙面との摺動をなくすことができることから、中綴じ冊子Ｂの紙面に摺動痕等を残すことなく中綴じ冊子Ｂを支持することができ、中綴じ冊子Ｂをより美しい状態で保つことができる。   In addition, since the extending member 343 extends to the edge end side of the saddle-stitched booklet B before the pinching of the saddle-stitched booklet B by the sandwiching members 341 and 342 is completed, the extending member 343 and the saddle-stitched booklet are bound. Since the sliding of the booklet B with the cover surface can be eliminated, the saddle-stitched booklet B can be supported without leaving a sliding mark on the paper surface of the saddle-stitched booklet B. Can keep in.

また、延出部材３４３は、挟持部材３４１に対して回動することで小口端部側に延出するよう設けられるので、より簡易な構成により延出部材３４３を延出させることができる。   Further, since the extending member 343 is provided so as to extend toward the fore edge end side by rotating with respect to the holding member 341, the extending member 343 can be extended with a simpler configuration.

また、中綴じ冊子Ｂの背表紙の折り目と小口端部との間の長さＱに応じて挟持部材３４１に対する延出部材３４３の延出量を調節するので、延出部材３４３の延出量を中綴じ冊子Ｂのサイズに応じた最適な延出量として小口端部側を支持することができる。   Moreover, since the extension amount of the extension member 343 with respect to the clamping member 341 is adjusted according to the length Q between the fold of the spine of the saddle stitch booklet B and the edge of the fore edge, the extension amount of the extension member 343 Can be supported on the edge end side as an optimal extension amount according to the size of the saddle stitch booklet B.

また、延出部材３４３は、断裁部３７０と小口端部側に延出した延出部材３４３とが当接しない延出量となるよう調節されるので、延出部材３４３と断裁部３７０とが当接して断裁処理が妨げられることを防止することができ、よりスムースに断裁処理を行うことができる。即ち、延出部材３４３による中綴じ冊子Ｂの小口端部側の末広がりの防止と、スムースな断裁処理とを両立することができる。   Further, since the extending member 343 is adjusted so that the extending portion 370 and the extending member 343 extending toward the edge end side do not come into contact with each other, the extending member 343 and the cutting portion 370 are adjusted. It is possible to prevent the cutting process from being disturbed by contact, and the cutting process can be performed more smoothly. That is, it is possible to achieve both the prevention of the end spread of the saddle-stitched booklet B on the edge end side by the extending member 343 and the smooth cutting process.

また、用紙処理装置３００は、中綴じ冊子Ｂを挟んで設けられた二つの挟持部材３４１、３４２を有し、一方の挟持部材３４１を他方の挟持部材３４２に近接させるよう動作させることで中綴じ冊子Ｂを挟持し、延出部材３４３は、一方の挟持部材３４１に設けられるので、中綴じ冊子Ｂの挟持に際して移動する挟持部材３４１の挟持面積をよりコンパクトにして周囲の構成との衝突を防止したうえで、延出部材３４３によって中綴じ冊子Ｂの末広がりを防止することができ、挟持面積によらず中綴じ冊子Ｂの背表紙側から小口端部側に渡る広範囲を支持することができる。
即ち、仮に挟持部材３４１が延出部材３４３の延出量に応じた挟持面を有する場合、用紙処理装置３００内の各構成（例えば、用紙処理装置３００の筐体や、受け渡し部３６０等）と挟持部材３４１とが衝突する可能性があるが、本実施形態のように、挟持部材３４１から延出部材３４３が延設可能に設けられることにより、挟持部材３４１の動作に伴う衝突をなくすことができ、より簡易に末広がりを防止することができる。 Further, the sheet processing apparatus 300 includes two sandwiching members 341 and 342 provided with the saddle stitch booklet B sandwiched therebetween, and the saddle stitching operation is performed by bringing one sandwiching member 341 close to the other sandwiching member 342. Since the booklet B is sandwiched and the extending member 343 is provided on one of the sandwiching members 341, the sandwiching area of the sandwiching member 341 that moves when the saddle-stitched booklet B is sandwiched is made more compact to prevent collision with the surrounding structure. In addition, the extending member 343 can prevent the saddle-stitched booklet B from spreading out, and can support a wide range from the back cover side of the saddle-stitched booklet B to the edge end side regardless of the sandwiching area.
That is, if the clamping member 341 has a clamping surface corresponding to the extension amount of the extending member 343, each configuration in the sheet processing apparatus 300 (for example, the casing of the sheet processing apparatus 300, the delivery unit 360, etc.) Although there is a possibility that the holding member 341 may collide, as in the present embodiment, the extension member 343 can be extended from the holding member 341 so that the collision caused by the operation of the holding member 341 can be eliminated. Can be prevented more easily.

また、二つの挟持部材３４１、３４１のうち他方の挟持部材３４２側において、他方の挟持部材３４２の挟持面に沿うよう設けられて二つの挟持部材３４１、３４２により挟持された中綴じ冊子Ｂの他方側の小口端部側を他方の挟持部材３４２の挟持面に沿わせるように中綴じ冊子を支持する延設部材としてのガイドワイヤー３５０を備えるので、一方の挟持部材３４１に設けられた延出部材３４３と併せて、他方の挟持部材３４２側の小口端部の末広がりをより良好に防止することができる。   The other of the saddle-stitched booklet B provided on the other clamping member 342 side of the two clamping members 341 and 341 along the clamping surface of the other clamping member 342 and clamped by the two clamping members 341 and 342. Since the guide wire 350 is provided as an extending member that supports the saddle-stitched booklet so that the small edge end side on the side is along the holding surface of the other holding member 342, the extending member provided on the one holding member 341 Together with 343, it is possible to better prevent the end of the fore end on the other clamping member 342 side from spreading.

また、延設部材がワイヤー（ガイドワイヤー３５０）であるので、用紙処理装置３００内で延設部材が占める設置範囲を最小限とすることができる。   Further, since the extending member is a wire (guide wire 350), the installation range occupied by the extending member in the sheet processing apparatus 300 can be minimized.

また、連動機構３５１により、搬送駆動部３４４による挟持部材３４１、３４２の移動に連動してガイドワイヤー３５０を挟持部材３４１、３４２の移動方向に沿って移動させることができるので、ガイドワイヤー３５０と中綴じ冊子Ｂの表紙面との摺動をなくすことができることから、中綴じ冊子Ｂの紙面に摺動痕等を残すことなく中綴じ冊子Ｂを支持することができ、中綴じ冊子Ｂをより美しい状態で保つことができる。   Further, the interlock mechanism 351 can move the guide wire 350 along the movement direction of the sandwiching members 341 and 342 in conjunction with the movement of the sandwiching members 341 and 342 by the transport driving unit 344. Since it is possible to eliminate sliding with the front cover of the saddle-stitched booklet B, the saddle-stitched booklet B can be supported without leaving a sliding mark on the paper surface of the saddle-stitched booklet B, making the saddle-stitched booklet B more beautiful. Can be kept in a state.

なお、本発明の実施の形態は、今回開示された実施の形態はすべての点で例示であって制限的なものではないと考えられるべきである。本発明の範囲は上記した説明ではなくて特許請求の範囲によって示され、特許請求の範囲と均等の意味および範囲内でのすべての変更が含まれることが意図される。   The embodiment of the present invention should be considered that the embodiment disclosed this time is illustrative and not restrictive in all respects. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.

例えば、上記の実施形態における延出部材３４３は、回動軸が設けられた一端が挟持部材３４１の両端側に設けられ、回動により移動する他端側が収納時（非延出時）に挟持部材３４１の中心側に向いており、回動により他端側が中心側からその外側に向かって移動するよう設けられているが、一例であってこれに限られるものでない。   For example, the extending member 343 in the above-described embodiment has one end provided with a rotating shaft provided on both ends of the holding member 341, and the other end moved by turning is held when retracted (when not extended). Although it faces the center side of the member 341 and the other end side is provided so as to move from the center side toward the outside by rotation, this is an example and the present invention is not limited to this.

具体例としては、図６に示すように、回動軸が設けられた一端が挟持部材３４１の中心側で、他端側が外側に向いた延出部材３４３１を採用してもよい。この場合、中綴じ冊子Ｂの小口端部側の天地、即ち、上記の実施形態のようにＹ−Ｚ平面に沿うよう挟持された中綴じ冊子Ｂの小口端部側のＹ方向の両端Ｂ１、Ｂ２を支持することができるので、天地方向（例えば、Ｙ方向）の中央付近を支持する場合に比して、天地側から生じうる用紙の外側への反り返りをより良好に防止することができる。   As a specific example, as shown in FIG. 6, an extending member 3431 in which one end provided with a rotation shaft is the center side of the holding member 341 and the other end side faces outward may be adopted. In this case, the top and bottom of the saddle-stitched booklet B, that is, both ends B1 in the Y direction on the side of the fore-edge of the saddle-stitched booklet B sandwiched along the YZ plane as in the above-described embodiment, Since B2 can be supported, warping to the outside of the paper that can occur from the top side can be prevented better than when supporting the vicinity of the center in the top and bottom direction (for example, the Y direction).

また、図７に示すように、中綴じ冊子Ｂの小口端部に対して略平行に設けられた延出部材３４３２の両端を、連接状の連結部材３４３３、３４３３により小口端部側に延出可能に支持するようにしてもよい。この場合、中綴じ冊子Ｂの小口端部側をより広い範囲で支持することができ、末広がりをより良好に防止することができる。
なお、図７に示す連結部材３４３３、３４３３は延出部材３４３２の両端と連結されているが、一例であってこれに限られるものでない。例えば、パンタグラフ状の連結により延出部材３４３２を延出可能に支持してもよいし、パンタグラフ等による連結と図７に示すような両端との連結との両方を併用していてもよい。
また、図７に示す延出部材３４３２の天地方向（例えば、Ｙ方向）の長さを用紙処理装置３００で取り扱われる中綴じ冊子Ｂ等の用紙の最大幅以上とすることで、用紙のサイズによらず良好に末広がりを防止することができる。 Further, as shown in FIG. 7, both ends of the extending member 3432 provided substantially parallel to the small edge end portion of the saddle stitch booklet B are extended to the small edge end portion side by connecting members 3433 and 3433 connected to each other. You may make it support so that it is possible. In this case, the edge end side of the saddle-stitched booklet B can be supported in a wider range, and end spread can be prevented more favorably.
In addition, although the connection members 3433 and 3433 shown in FIG. 7 are connected with the both ends of the extension member 3432, it is an example and is not restricted to this. For example, the extending member 3432 may be supported by a pantograph-like connection, or both a connection by a pantograph or the like and a connection at both ends as shown in FIG. 7 may be used in combination.
Further, by setting the length of the extending member 3432 shown in FIG. 7 in the vertical direction (for example, the Y direction) to be equal to or larger than the maximum width of the sheet such as the saddle-stitched booklet B handled by the sheet processing apparatus 300, the size of the sheet is reduced. Regardless of this, it is possible to prevent the spread of the powder.

また、延出部材は、図４、図６、図７に示す具体例に限らない。例えば、挟持部材３４１から小口端部側に延出可能に設けられたシャッター構造の延出部材を採用してもよい。この場合、延出部材は、例えば、蛇腹構造や、複数枚の板が重畳された状態で収納されて延出に伴い段階的に板どうしの重なり合う面積が小さくなるように移動する連板構造等を有する。   Further, the extending member is not limited to the specific examples shown in FIGS. 4, 6, and 7. For example, you may employ | adopt the extending member of the shutter structure provided so that it could extend from the clamping member 341 to the edge edge part side. In this case, the extending member is, for example, a bellows structure, a continuous plate structure that is accommodated in a state where a plurality of plates are superimposed, and moves so that the overlapping area of the plates gradually decreases as it extends. Have

また、上記の実施形態では、延出部材３４３の延出量を確定させたうえで搬送ユニットＵを上下動させて中綴じ冊子Ｂを搬送しているが、中綴じ冊子Ｂの搬送に伴って延出部材３４３の延出量を調節するようにしてもよい。
具体的には、例えば、図８の位置Ｐ３に示すように、挟持部材３４１、３４２による中綴じ冊子Ｂの挟持時や、挟持後に行われる搬送ユニットＵの下降開始から中綴じ冊子Ｂの小口端部が断裁部３７０への進入を開始するまでは、中綴じ冊子Ｂの小口端部側において断裁部３７０の構成が当接する範囲Ｑ１、Ｑ２及び所定のマージンＭを超えて下方まで中綴じ冊子Ｂの小口端部側を延出部材３４３により支持することにより、末広がりをより確実に防止するようにしてもよい。そして、中綴じ冊子Ｂの小口端部が断裁部３７０への進入を開始することに伴い、延出部材３４３の他端側を上方に回動させて断裁部３７０の構成が当接する範囲Ｑ１、Ｑ２よりも上方の位置（例えば、図８に示す位置Ｐ２等）に移動させることにより、断裁部３７０と延出部材３４３とを当接させることなくスムースに断裁部３７０による断裁処理へと移行することができる。 Further, in the above embodiment, after the extension amount of the extending member 343 is determined, the conveyance unit U is moved up and down to convey the saddle-stitched booklet B. However, as the saddle-stitched booklet B is conveyed, The extending amount of the extending member 343 may be adjusted.
Specifically, for example, as shown at a position P3 in FIG. 8, when the saddle-stitched booklet B is sandwiched by the sandwiching members 341 and 342, or from the start of the lowering of the transport unit U performed after the sandwiching, the small edge of the saddle-stitched booklet B Until the section starts to enter the cutting section 370, the saddle-stitched booklet B extends to the lower side beyond the ranges Q1 and Q2 where the configuration of the cutting section 370 abuts on the small edge end side of the saddle-stitched booklet B and a predetermined margin M. By supporting the fore edge end side by the extending member 343, it is possible to prevent the end spread more reliably. Then, as the fore edge portion of the saddle-stitched booklet B starts entering the cutting portion 370, a range Q1 in which the configuration of the cutting portion 370 contacts by rotating the other end side of the extending member 343 upward, By moving to a position above Q2 (for example, the position P2 shown in FIG. 8), the cutting unit 370 smoothly moves to the cutting process by the cutting unit 370 without contacting the extending member 343. be able to.

また、上記の実施形態では、挟持部材３４１、３４２による中綴じ冊子Ｂの背表紙側の挟持が完了する前に延出部材３４３を中綴じ冊子Ｂの小口端部側に延出しているが、挟持部材３４１、３４２による中綴じ冊子Ｂの背表紙側の挟持が完了した後に延出部材３４３を中綴じ冊子Ｂの小口端部側に延出するようにしてもよい。
例えば、挟持部材３４１の小口端部側の開放空間が上記の実施形態よりも確保できず、挟持部材３４１、３４２による中綴じ冊子Ｂの背表紙側の挟持が完了する前に延出部材３４３を中綴じ冊子Ｂの小口端部側に延出した場合に延出部材３４３と他の構成とが衝突する可能性がある場合等において、挟持部材３４１、３４２による中綴じ冊子Ｂの背表紙側の挟持が完了した後に延出部材３４３を中綴じ冊子Ｂの小口端部側に延出することで、より限定された用紙処理装置３００内の空間内であっても延出部材３４３による末広がりの防止を実現することができる。 In the above embodiment, the extending member 343 extends to the edge end side of the saddle-stitched booklet B before the pinching of the saddle-stitched booklet B by the sandwiching members 341 and 342 is completed. The extension member 343 may be extended to the small edge end side of the saddle-stitched booklet B after the clamping of the saddle-stitched booklet B by the sandwiching members 341 and 342 is completed.
For example, the open space on the small edge end side of the clamping member 341 cannot be secured as compared with the above embodiment, and the extension member 343 is installed before the clamping of the saddle-stitched booklet B by the clamping members 341 and 342 is completed. When there is a possibility that the extending member 343 collides with another configuration when the saddle-stitched booklet B is extended to the edge end side, the saddle-stitched booklet B on the back cover side of the saddle-stitched booklet B is clamped. By extending the extending member 343 to the edge end side of the saddle-stitched booklet B after the clamping is completed, it is possible to prevent the extending member 343 from spreading even in a more limited space in the sheet processing apparatus 300. Can be realized.

また、上記の実施形態において、延設部材としてガイドワイヤー３５０が設けられているが、一例であってこれに限られるものでない。例えば、布やネット、メッシュ等、膜状態の部材を上記のガイドワイヤー３５０と同様の延設方向に沿って設けてもよい。   Moreover, in said embodiment, although the guide wire 350 is provided as an extending member, it is an example and is not restricted to this. For example, a film-like member such as a cloth, a net, or a mesh may be provided along the extending direction similar to the guide wire 350 described above.

また、上記の実施形態において、延設部材であるガイドワイヤー３５０は、中綴じ冊子Ｂの搬送に伴う挟持部材３４１、３４２の移動に連動して移動しているが、一例であってこれに限られるものでない。
例えば、ガイドワイヤー３５０を挟持部材３４２に対してＺ方向に沿って挿通させるように固定して延設することで、固定されたガイドワイヤー３５０に対し、搬送ユニットＵの上下動に伴う挟持部材３４２の移動を実現することができる。この場合、連動機構３５１を省略することができるので、上記の実施形態よりも簡易な構造により中綴じ冊子の支持を行うことができる。 Further, in the above embodiment, the guide wire 350 as the extending member moves in conjunction with the movement of the sandwiching members 341 and 342 accompanying the conveyance of the saddle stitch booklet B. However, this is only an example. It is not something that can be done.
For example, the guide wire 350 is fixed and extended so as to be inserted in the Z direction with respect to the holding member 342, so that the holding member 342 accompanying the vertical movement of the transport unit U with respect to the fixed guide wire 350. Can be realized. In this case, since the interlocking mechanism 351 can be omitted, the saddle-stitched booklet can be supported with a simpler structure than the above embodiment.

また、上記の実施形態では、一方の挟持部材３４１に延出部材３４３が設けられ、他方の挟持部材３４２側にガイドワイヤー３５０が設けられているが、両方の挟持部材３４１、３４２に延出部材を設けるようにしてもよい。
また、上記の実施形態では、他方の挟持部材３４２はＸ方向について固定されており、一方の挟持部材３４１が他方の挟持部材３４２に対してＸ方向に沿って直動することにより中綴じ冊子Ｂを挟持しているが、中綴じ冊子に対して二つの挟持部材が互いに近接又は離隔するように設けてもよい。 Further, in the above embodiment, the extending member 343 is provided on one of the holding members 341 and the guide wire 350 is provided on the other holding member 342 side. However, the extending members are provided on both of the holding members 341 and 342. May be provided.
In the above embodiment, the other holding member 342 is fixed in the X direction, and the one holding member 341 moves linearly along the X direction with respect to the other holding member 342, so that the saddle-stitched booklet B However, the two holding members may be provided close to or separated from each other with respect to the saddle stitch booklet.

また、上記の実施形態では、中綴じ冊子Ｂが挟持部材３４１、３４２に挟持される例について記載しているが、一例であってこれに限られるものでない。例えば、中折りされた一枚の用紙や、中折りされた用紙が折り目で重ね合わされた複数の用紙であってもよい。この場合、挟持部材３４１、３４２は、中折りされた用紙の折り目側を担持し、延出部材３４３や延設部材は、用紙の折り目側に対向する小口端部側を案内する。   In the above-described embodiment, an example in which the saddle stitch booklet B is sandwiched between the sandwiching members 341 and 342 is described, but this is an example and the present invention is not limited thereto. For example, it may be a single folded sheet or a plurality of folded sheets. In this case, the holding members 341 and 342 carry the fold side of the folded sheet, and the extending member 343 and the extending member guide the edge end side facing the fold side of the sheet.

また、上記の実施形態では、延出部材３４３が挟持部材３４１から延出可能に設けられているが、一例であってこれに限られるものでなく、別の箇所から延出可能に設けられていてもよい。例えば、挟持部材３４１、３４２により挟持された中綴じ冊子Ｂの側方から延出部材３４３等を延出可能に支持する支持部材を搬送ユニットＵに設ける等の構成をとってもよい。   In the above embodiment, the extending member 343 is provided so as to be able to extend from the clamping member 341.
