前記表紙折り加工部が、
前記表紙用紙の前記端部に前記折筋が形成された前記用紙束を搬送する搬送手段と、前記搬送手段で搬送された前記用紙束の前記表紙用紙の前記端部が突き当たる表紙付き当て部材と、前記表紙付き当て部材に突き当てられた前記表紙用紙の前記端部を前記折筋から巻き込む表紙折りローラと、を具備することを特徴としている。 The bookbinding apparatus according to claim 3 is the bookbinding apparatus according to claim 1 or 2,
The cover folding section is
A conveying unit configured to convey the sheet bundle in which the folding line is formed at the end portion of the cover sheet; and a cover attaching member on which the end portion of the cover sheet of the sheet bundle conveyed by the conveying unit abuts. And a cover folding roller for winding the end portion of the cover sheet abutted against the cover cover abutting member from the fold line.

請求項１に記載された製本装置によれば、用紙束の小口から表紙用紙の端部が突出している状態で、表紙用紙にくるまれた用紙束を、表紙折筋加工部で処理する。これにより、用紙束の小口から突出している表紙用紙の端部に、小口の端辺に沿った折筋を形成することができる。表紙折筋加工部で処理された用紙束は、後段の表紙折り加工部に送られ、表紙折り加工部は、表紙用紙の端部を折筋に沿って表紙用紙の裏側に折り込む。これにより、表紙用紙を用紙束に合わせて切断することなく、用紙束の小口の２つの端辺と、この用紙束をくるむ表紙用紙の小口に近い２つの端辺とを一致させて、装丁の質感の高い高品質な冊子を製作することができる。 According to the bookbinding apparatus of the first aspect, the cover sheet folding line processing unit processes the sheet bundle wrapped around the cover sheet in a state where the edge of the cover sheet protrudes from the edge of the sheet bundle. Thereby, a crease along the edge of the fore edge can be formed at the end of the cover sheet protruding from the fore edge of the sheet bundle. The sheet bundle processed by the cover sheet folding line processing unit is sent to the subsequent cover sheet folding unit, and the cover sheet folding unit folds the end of the cover sheet along the folding line to the back side of the cover sheet. This makes it possible to match the two edges of the fore edge of the sheet bundle with the two edges near the fore edge of the cover sheet that wraps the bundle of sheets without cutting the cover sheet in line with the sheet bundle. A high-quality booklet with high quality can be produced.

請求項２に記載された製本装置によれば、表紙用紙に折筋を形成する工程を一対の折筋加工ローラを用いて次のように行うことができる。すなわち、表紙用紙でくるまれた用紙束を、一対の折筋加工ローラで厚さ方向に挟持し、用紙束の背を搬送方向の前方に向けて搬送する。一対の折筋加工ローラを用紙束の小口が通過すると、表紙用紙の端部が小口の端辺に押し付けられ、表紙用紙の端部に折筋が形成される。このように表紙用紙の端部に折筋を形成する複雑な工程を一対の折筋加工ローラという簡便な構成で実現できる。 According to the bookbinding apparatus of the second aspect, the step of forming the folding line on the cover sheet can be performed as follows using the pair of folding line processing rollers. That is, a sheet bundle wrapped with cover sheets is sandwiched in the thickness direction by a pair of folding lines processing rollers, and conveyed with the back of the sheet bundle directed forward in the conveying direction. When the fore edge of the sheet bundle passes through the pair of folding line processing rollers, the end of the cover sheet is pressed against the edge of the fore edge, and a folding line is formed at the end of the cover sheet. Thus, the complicated process of forming a folding line at the end of the cover sheet can be realized with a simple configuration of a pair of folding line processing rollers.

請求項３に記載された製本装置によれば、用紙束の搬送手段と、表紙用紙が突き当たる表紙付き当て部材と、表紙用紙の端部を折筋から巻き込む表紙折りローラからなる表紙折り加工部により、表紙用紙の端部を折筋に沿って表紙用紙の裏側に折り込む工程を次のように行うことができる。すなわち、表紙用紙の端部に折筋が形成された用紙束を搬送手段で所定方向に搬送する。搬送手段で搬送された用紙束の表紙用紙の端部が表紙付き当て部材に突き当たると、表紙用紙は折筋が凸になる状態に撓み、折筋が表紙折りローラに巻き込まれていく。表紙用紙の折筋よりも先の部分の長さだけ表紙折りローラが表紙用紙を巻き込んだら、折りローラを逆転させるとともに、搬送手段を所定方向と反対の方向に駆動する。表紙用紙の折筋よりも先の部分が表紙用紙の裏側、すなわち用紙束の側に折り返されて、用紙束の小口の端辺と、表紙用紙の折筋とが一致し、装丁の質感の高い高品質な冊子が製作される。このように、表紙用紙の端部を折筋に沿って表紙用紙の裏側に折り込む複雑な工程を、搬送手段と表紙付き当て部材と表紙折りローラという簡便な構成で実現できる。 According to the bookbinding apparatus described in claim 3, the cover folding unit includes a sheet bundle conveying unit, a cover attaching member against which the cover sheet abuts, and a cover folding roller that winds an end of the cover sheet from the folding line. The process of folding the end of the cover sheet along the folding line to the back side of the cover sheet can be performed as follows. That is, a sheet bundle in which folding lines are formed at the end of the cover sheet is conveyed in a predetermined direction by the conveying unit. When the end portion of the cover sheet of the sheet bundle conveyed by the conveying means hits the cover cover attaching member, the cover sheet is bent in a state where the fold line becomes convex, and the fold line is wound around the cover folding roller. When the cover sheet folding roller entrains the cover sheet by the length of the portion ahead of the folding line of the cover sheet, the folding roller is reversed and the conveying means is driven in a direction opposite to the predetermined direction. The part ahead of the folding line of the cover sheet is folded back to the back side of the cover sheet, that is, the side of the sheet bundle, the edge of the edge of the sheet bundle matches the folding line of the cover sheet, and the texture of the binding is high A high-quality booklet is produced. In this way, a complicated process of folding the end of the cover sheet along the folding line to the back side of the cover sheet can be realized with a simple configuration of the conveying means, the cover attaching member, and the cover folding roller.

The printing apparatus 2 performs necessary printing as standard paper defined in the standard as text paper, and performs necessary printing as non-standard paper cut from roll paper having a size larger than the text paper as cover paper. This is supplied to the subsequent bookbinding apparatus 3. The bookbinding apparatus 3 creates a sheet bundle from the body paper sent from the printing apparatus 2, performs binding binding by binding the sheet bundle with the cover sheet sent from the printing apparatus 2, and protrudes from the edge of the sheet bundle. A bookbinding operation can be performed in which the cover sheet is folded back to adjust the form of the booklet.

まず、図１を参照して印刷装置２について説明する。
印刷装置２は、給紙部４と、印刷部５と、排紙部６と、これら各部の間を結ぶ太線の矢印で示した用紙の搬送経路７と、各部を制御する印刷制御部８と、以上の各構成部分を収納または保持する筐体９を備えている。 First, the printing apparatus 2 will be described with reference to FIG.
The printing apparatus 2 includes a paper feeding unit 4, a printing unit 5, a paper discharge unit 6, a paper transport path 7 indicated by a thick arrow connecting these units, and a print control unit 8 that controls each unit. The housing 9 is provided for storing or holding the above-described components.

図示しないが、搬送経路７にはモータで駆動される搬送ローラが適宜間隔で設けられており、搬送経路７に沿って用紙を連続的に搬送することができる。搬送経路７は、ループ状の周回路７ａと、給紙部４と周回路７ａを接続する供給路７ｂと、用紙を排出し、又は用紙の表裏を反転させるために周回路７ａに接続して設けられた反転路７ｃと、製本装置３に用紙を送り出すために周回路７ａに接続して設けられた連絡路７ｄとを有している。 Although not shown, conveyance rollers driven by a motor are provided at appropriate intervals in the conveyance path 7, and the paper can be continuously conveyed along the conveyance path 7. The conveyance path 7 is connected to the loop circuit 7a, the supply path 7b connecting the paper feed unit 4 and the circuit 7a, and the circuit 7a for discharging the paper or inverting the front and back of the paper. The reversing path 7 c is provided, and a communication path 7 d is provided that is connected to the peripheral circuit 7 a in order to send the paper to the bookbinding device 3.

給紙部４は、印刷部５に用紙を供給するために搬送経路７の供給路７ｂに用紙を送り出す。給紙部４は、搬送経路７の最も上流側に配置されており、外部給紙台４ａと、複数の内部給紙台４ｂを備えており、モータで駆動される給紙ローラで用紙を供給路７ｂに送り出すことができる。なお、ここで、外部給紙台４ａと内部給紙台４ｂを総称して給紙トレイと称する。外部給紙台４ａ及び内部給紙台４ｂから１枚ずつ搬送経路７の供給路７ｂに送り出された用紙は、後述するレジストローラ５ａへ向けて搬送される。 The paper feed unit 4 sends the paper to the supply path 7 b of the transport path 7 in order to supply the paper to the printing unit 5. The paper feed unit 4 is arranged on the most upstream side of the transport path 7 and includes an external paper feed stand 4a and a plurality of internal paper feed stands 4b, and supplies paper with a paper feed roller driven by a motor. It can be sent to the road 7b. Here, the external paper feed tray 4a and the internal paper feed tray 4b are collectively referred to as a paper feed tray. The sheets fed one by one from the external sheet feed table 4a and the internal sheet feed table 4b to the supply path 7b of the conveyance path 7 are conveyed toward a registration roller 5a described later.

印刷部５は、用紙を搬送しつつ、用紙に画像を印刷する。印刷部５は、給紙部４の下流側に配置されており、レジストローラ５ａと、ベルト搬送部５ｂと、Ｋ（ブラック）、Ｃ（シアン）、Ｍ（マゼンタ）、Ｙ（イエロー）の各色のインクを吐出する４つのインクジェットヘッド５ｃから構成される。レジストローラ５ａは、供給路７ｂと周回路７ａの合流地点の近傍に配置されており、供給路７ｂまたは反転路７ｃから搬送されてきた用紙を一旦止めた後、所定のタイミングでベルト搬送部５ｂに向けて搬送することができる。ベルト搬送部５ｂは、レジストローラ５ａの下流側に配置されており、レジストローラ５ａから搬送されてきた用紙をベルト上に吸着保持して搬送する。印刷部５の各インクジェットヘッド５ｃは、ベルト搬送部５ｂの上方に配置されている。各インクジェットヘッド５ｃは、用紙の搬送方向と略直交する方向に配列された複数のノズルを備えており、ベルト搬送部５ｂが搬送する用紙にインクを吐出して画像を形成する。 The printing unit 5 prints an image on a sheet while conveying the sheet. The printing unit 5 is disposed on the downstream side of the paper feeding unit 4, and each color of K (black), C (cyan), M (magenta), and Y (yellow) is a registration roller 5a, a belt conveyance unit 5b. It is comprised from the four inkjet heads 5c which discharge the ink of this. The registration roller 5a is disposed in the vicinity of the joining point of the supply path 7b and the peripheral circuit 7a. After temporarily stopping the sheet conveyed from the supply path 7b or the reversing path 7c, the belt conveyance unit 5b at a predetermined timing. It can be transported toward. The belt conveyance unit 5b is disposed on the downstream side of the registration roller 5a, and conveys the sheet conveyed from the registration roller 5a by sucking and holding the sheet on the belt. Each inkjet head 5c of the printing unit 5 is disposed above the belt conveyance unit 5b. Each inkjet head 5c includes a plurality of nozzles arranged in a direction substantially orthogonal to the paper transport direction, and forms an image by ejecting ink onto the paper transported by the belt transport unit 5b.

排紙部６は、製本を行わずに印刷のみを行う場合に、印刷済みの用紙が排出されるトレイ状の部分である。印刷部５で印刷された用紙は、周回路７ａに沿って搬送され、周回路７ａの一部に設けられて用紙の搬送方向を任意に切り替える反転路７ｃを経て排紙部６に排出される。用紙の搬送方向は、反転路７ｃにおける用紙の搬送方向を切り替えることにより、任意に選択することができる。すなわち、周回路７ａを搬送されてきた用紙を、上述したように反転路７ｃを経て排紙部６に搬送して機外に排出することもできるし、反転路７ｃを経て周回路７ａに戻し、そのまま周回路７ａを搬送させることもできる。さらに、用紙を反転路７ｃを経て排紙部６の方向に搬送した後、排紙部６に排出することなく一端反転路７ｃで停止し、反転路７及び周回路７ａの搬送ローラを逆転させれば、用紙の表裏を反転させて用紙を周回路７ａに戻すことができる。用紙の表裏の反転は、用紙の表裏両面に印刷する両面印刷の場合に利用される。
なお、図１に模式的に示し、これを参照して上に説明した反転路７ｃの機能は、例えば周回路７ａから分岐した一以上の枝状搬送路と、周回路７ａと枝状搬送路の間に設けられた切替え手段等によって構成できるが、その構造は任意であり、具体的な特定構造のみに限定するものではない。 The paper discharge unit 6 is a tray-like portion from which printed paper is discharged when only printing is performed without bookbinding. The paper printed by the printing unit 5 is transported along the peripheral circuit 7a, and is discharged to the paper discharge unit 6 through an inversion path 7c that is provided in a part of the peripheral circuit 7a and arbitrarily switches the paper transport direction. . The paper transport direction can be arbitrarily selected by switching the paper transport direction in the reversing path 7c. That is, the sheet conveyed through the peripheral circuit 7a can be transported to the paper discharge unit 6 through the reverse path 7c as described above and discharged outside the apparatus, or returned to the peripheral circuit 7a through the reverse path 7c. The peripheral circuit 7a can be transported as it is. Further, after the sheet is conveyed in the direction of the paper discharge unit 6 through the reverse path 7c, it is stopped at the one-way reverse path 7c without being discharged to the paper discharge unit 6, and the reverse rollers 7 and the conveying rollers of the peripheral circuit 7a are reversed. Then, the front and back of the paper can be reversed and the paper can be returned to the peripheral circuit 7a. Inversion of the front and back of the paper is used in the case of double-sided printing that prints on both front and back sides of the paper.
The function of the inversion path 7c schematically shown in FIG. 1 and described above with reference to this is, for example, one or more branch transport paths branched from the peripheral circuit 7a, and the peripheral circuit 7a and the branch transport path However, the structure is arbitrary, and is not limited to a specific specific structure.

搬送経路７の連絡路７ｄは、印刷装置２を製本装置３に接続しており、製本作業時に使用される。この連絡路７ｄには、用紙を搬送する連絡ローラ７ｅと、図示しない切替部が設けられている。切替部は、周回路７ａと連絡路７ｄの間に設けられ、用紙の搬送経路７を周回路７ａと連絡路７ｄの何れか一方に切り替える。製本作業時、切替部を製本装置３の側に切り替えれば、印刷装置２で印刷された用紙を製本装置３へと送り出すことができる。 The communication path 7d of the transport path 7 connects the printing apparatus 2 to the bookbinding apparatus 3 and is used during bookbinding operations. The communication path 7d is provided with a communication roller 7e for conveying paper and a switching unit (not shown). The switching unit is provided between the peripheral circuit 7a and the communication path 7d, and switches the paper transport path 7 to one of the peripheral circuit 7a and the communication path 7d. If the switching unit is switched to the bookbinding device 3 side during bookbinding, paper printed by the printing device 2 can be sent to the bookbinding device 3.

印刷制御部８は、印刷装置２の各部の動作を制御する。印刷制御部８は、ＣＰＵ、ＲＡＭ、ＲＯＭ、ハードディスク等を備えて構成される。機能及び作用の詳細は後述するが、この印刷制御部８は、後述する製本制御部１８と協働し、与えられたジョブの内容に応じて印刷作業又は製本作業に適した本文用紙及び表紙用紙が収納された給紙トレイを選択して必要な印刷を行う機能を備えている。なお、この印刷制御部８と、後述する製本制御部１８は、何れか一方のみで両方の機能を備えて製本システム１の全体を制御できるようにしてもよい。 The print control unit 8 controls the operation of each unit of the printing apparatus 2. The print control unit 8 includes a CPU, a RAM, a ROM, a hard disk, and the like. Although the details of the functions and operations will be described later, the print control unit 8 cooperates with a bookbinding control unit 18 to be described later, and a body sheet and a cover sheet suitable for printing work or bookbinding work according to the contents of a given job. Is provided with a function of selecting a paper feed tray in which is stored and performing necessary printing. The print control unit 8 and the bookbinding control unit 18 to be described later may be configured to control both the functions of the bookbinding system 1 with only one of them.

次に、図１〜図４を参照して製本装置３について説明する。
製本装置３はくるみ製本機能により冊子を作製する。くるみ製本機能とは、複数枚の本文用紙Ｐ１を重ねて整合することで用紙束ＰＳを作成し、これを表紙用紙Ｐ２でくるみ綴じして冊子Ｂを成形する機能である。なお、一般的には、用紙束ＰＳを作成する本文用紙Ｐ１には定型用紙を使用し、用紙束ＰＳをくるむ表紙用紙Ｐ２には、通常は定型用紙だと必要な長さが得られないので、ロール紙などから必要長さの表紙用紙を切り出して用意しておくのが好ましい。 Next, the bookbinding apparatus 3 will be described with reference to FIGS.
The bookbinding apparatus 3 creates a booklet by the case binding function. The case binding function is a function of forming a booklet B by creating a sheet bundle PS by stacking and aligning a plurality of body sheets P1 and binding them with a cover sheet P2. In general, a standard paper is used as the body paper P1 for creating the paper bundle PS, and the cover paper P2 that encloses the paper bundle PS usually cannot have a required length if it is a standard paper. It is preferable to prepare a cover sheet having a required length from roll paper or the like.

図１に示すように、製本装置３は、印刷装置２の連絡路７ｄから図中略垂直に立ち上がる太線の矢印で示した本文搬送路１０と、印刷装置２の連絡路７ｄから図中水平に連続する太線の矢印及び細い細線で示す表紙搬送路１１を、用紙の搬送経路として備えている。さらに、製本装置３は、本文搬送路１０の終端に設けられた図示しない整合部と、整合部で整合された用紙束ＰＳを挟んで移動させるクランプ部１２と、用紙束ＰＳに接着剤を塗布する接着剤塗布部１３と、表紙搬送路１１の終端に設けられた成形部１４と、成形部１４と接着剤塗布部１３の間に設けられた表紙折筋加工部１５と、表紙折筋加工部１５の下方に設けられた表紙折り加工部１６と、完成した冊子Ｂを筐体９の外部に排出する排出部１７と、製本装置３の全体を制御する製本制御部１８と、これら各部を収納または保持する筐体９を備えている。 As shown in FIG. 1, the bookbinding device 3 is continuous horizontally from the communication path 7d of the printing apparatus 2 to the text conveyance path 10 indicated by the thick line arrows rising substantially vertically in the figure and from the communication path 7d of the printing apparatus 2 to the horizontal in the figure.

If the sheet bundle PS is sandwiched by driving in this direction, the booklet B can be formed by binding the sheet bundle PS with the cover sheet P2.

図１に示すように、成形部１４と接着剤塗布部１３の間には、表紙折筋加工部１５が設けられている。この表紙折筋加工部１５は、表紙用紙Ｐ２でくるまれた用紙束ＰＳの小口ＰＳｂから、表紙用紙Ｐ２の端部が突出している場合に、この突出している表紙用紙Ｐ２の端部Ｅを、小口ＰＳｂの端辺に押し付けることにより、表紙用紙Ｐ２の端部Ｅに折筋Ｆ（折り目）を形成する装置である。 As shown in FIG. 1, a cover folding line processing part 15 is provided between the forming part 14 and the adhesive application part 13. When the end portion of the cover sheet P2 protrudes from the fore edge PSb of the sheet bundle PS wrapped with the cover sheet P2, the cover folding line processing unit 15 uses the end E of the protruding cover sheet P2 as follows. It is an apparatus that forms a crease F (fold) at the end E of the cover sheet P2 by pressing against the edge of the fore edge PSb.

図２に拡大して示したように、この表紙折筋加工部１５は、所定間隔をおいて左右に並んだ対の折筋加工ローラ３０，３０を、上下方向に所定間隔をおいて同位置に配置したものである。上のローラ対を第１折筋加工ローラ３０と称し、下のローラ対を第２折筋加工ローラ３０と称する。第１及び第２折筋加工ローラ３０，３０は、ローラ対の間に挟んだ用紙束ＰＳを下方へ搬送する方向に駆動可能である。 As shown in an enlarged view in FIG. 2, the cover folding line processing unit 15 has a pair of folding line processing rollers 30, 30 arranged side by side at a predetermined interval at the same position in the vertical direction. It is arranged in. The upper roller pair is referred to as a first folding line processing roller 30, and the lower roller pair is referred to as a second folding line processing roller 30. The first and second folding line processing rollers 30 and 30 can be driven in a direction in which the sheet bundle PS sandwiched between the roller pair is conveyed downward.

なお、後述するように、この折筋加工ローラ３０は、表紙用紙Ｐ２に折筋Ｆを形成するために必ずしも２対が必要とは限らないが、２対あれば、表紙用紙Ｐ２に折筋Ｆを付ける作用が確実になるとともに、用紙束ＰＳを下方に搬送する作用がより安定する効果が得られる。 As will be described later, the folding line processing roller 30 does not necessarily need two pairs for forming the folding line F on the cover sheet P2, but if there are two pairs, the folding line F is formed on the cover sheet P2. As a result, the operation of feeding the sheet bundle PS downward is more stable.

第１及び第２折筋加工ローラ３０の各ローラ対の間隔は調整自在であり、本実施形態では用紙束ＰＳを挟んだクランプ部１２のクランプ板の間隔と同等に設定するものとする。ここで、用紙束ＰＳを挟んだ一対のクランプ板の間隔は、前述したように厚さセンサによって検出できるので、この厚さセンサの検出結果に応じて、各ローラ対３０，３０の間隔を用紙束ＰＳの厚さと同じ値に自動的に設定することができる。この場合、第１及び第２折筋加工ローラ３０を弾性材料で構成し、用紙束ＰＳを挟持搬送した際、第１及び第２折筋加工ローラ３０が若干潰れることにより、表紙用紙Ｐ２の端部Ｅを小口ＰＳｂの端辺に押し付ける効果が十分に得られるようにすることが好ましい。 The interval between each pair of rollers of the first and second crease forming rollers 30 is adjustable, and in this embodiment, it is set to be equal to the interval between the clamp plates of the clamp portion 12 with the sheet bundle PS interposed therebetween. Here, since the distance between the pair of clamp plates sandwiching the sheet bundle PS can be detected by the thickness sensor as described above, the distance between the roller pairs 30 and 30 is determined according to the detection result of the thickness sensor. It can be automatically set to the same value as the thickness of the bundle PS. In this case, the first and second folding line processing rollers 30 are made of an elastic material, and when the sheet bundle PS is nipped and conveyed, the first and second folding line processing rollers 30 are slightly crushed, so that the end of the cover sheet P2 It is preferable to sufficiently obtain the effect of pressing the portion E against the edge of the fore edge PSb.

なお、表紙用紙Ｐ２に折筋Ｆを確実に加工するための第１及び第２折筋加工ローラ３０の構成としては、次のような構成も採用しうる。すなわち、第１及び第２折筋加工ローラ３０を樹脂製等、ある程度の剛性を有する材質とする。そして、第１及び第２折筋加工ローラ３０の各ローラ対の間隔を、厚さセンサの検出結果を利用し、各用紙束ＰＳの厚さよりも若干小さく設定する。そして、第１及び第２折筋加工ローラ３０が用紙束ＰＳを挟持搬送する場合、ローラ対の間隔が弾性的に若干広がり、用紙束ＰＳの挟持が解除されると、ローラ対の間隔が元の値に復帰できるように構成する。このようにしても、表紙用紙Ｐ２の端部Ｅを小口ＰＳｂの端辺に押し付ける効果は十分に得られる。 In addition, as a structure of the 1st and 2nd folding line process roller 30 for processing the folding line F to the cover paper P2 reliably, the following structures can also be employ | adopted. That is, the first and second folding line processing rollers 30 are made of a material having a certain degree of rigidity such as resin. Then, the distance between each pair of rollers of the first and second crease forming rollers 30 is set slightly smaller than the thickness of each sheet bundle PS using the detection result of the thickness sensor. When the first and second crease forming rollers 30 nipping and conveying the sheet bundle PS, the interval between the roller pairs is elastically slightly increased. When the nipping of the sheet bundle PS is released, the interval between the roller pairs is restored to the original. It is configured to be able to return to the value of. Even in this case, the effect of pressing the edge E of the cover sheet P2 against the edge of the fore edge PSb can be sufficiently obtained.

図１に示すように、表紙折筋加工部１５の下方には、第１の表紙折り加工部１６ａが設けられており、第１の表紙折り加工部１６ａの左側下方には、第２の表紙折り加工部１６ｂが設けられている。図３に拡大して示すように、これらの表紙折り加工部１６は、前工程で表紙用紙の端部Ｅに形成した折筋Ｆに沿って、表紙用紙の端部Ｅを折り、これを表紙用紙Ｐ２の裏側に折り込む装置である。すなわち、前段の表紙折筋加工部１５で、用紙束ＰＳの小口ＰＳｂから突出している表紙用紙Ｐ２の両端部Ｅにそれぞれ折筋Ｆを形成した後、第１の表紙折り加工部１６ａによって表紙用紙Ｐ２の一端部Ｅを折筋Ｆで折り返し、さらに第２の表紙折り加工部１６ｂによって表紙用紙Ｐ２の他端部Ｅを折筋Ｆで折り返すことにより、小口ＰＳｂ側の表紙に不揃いがなく、装丁の質感の高い冊子Ｂの形態に仕上げることができる。 As shown in FIG. 1, a first cover folding section 16a is provided below the cover folding line processing section 15, and a second cover is provided below the left side of the first cover folding processing section 16a.

次に、製本システム１における印刷装置２の基本的な印刷動作について説明する。
製本システム１が製本印刷動作を開始すると、印刷装置２において、内部給紙台４ｂから給紙経路７に本文用紙Ｐ１が供給され、印刷部５へ搬送される。印刷部５において、本文用紙Ｐ１は、レジストローラ５ａによりベルト搬送部３５へ搬送される。そして、本文用紙Ｐ１は、ベルト搬送部３５により搬送されつつ、インクジェットヘッド５ｃから吐出されるインクにより印刷される。 Next, a basic printing operation of the printing apparatus 2 in the bookbinding system 1 will be described.
When the bookbinding system 1 starts a bookbinding printing operation, in the printing apparatus 2, the body paper P <b> 1 is supplied from the internal paper feed tray 4 b to the paper feed path 7 and conveyed to the printing unit 5. In the printing unit 5, the text sheet P1 is conveyed to the belt conveyance unit 35 by the registration rollers 5a. The text sheet P1 is printed by ink ejected from the inkjet head 5c while being transported by the belt transport unit 35.

片面印刷の場合、片面印刷済みの本文用紙Ｐ１は、ベルト搬送部３５により搬送されつつ、図示しない切替部により周回路７ａから連絡路７ｄへ導かれ、連絡ローラ７ｅにより製本装置３へ送り出される。 In the case of single-sided printing, the single-side printed text sheet P1 is guided by the switching unit (not shown) from the peripheral circuit 7a to the communication path 7d while being conveyed by the belt conveyance unit 35, and is sent out to the bookbinding apparatus 3 by the communication roller 7e.

両面印刷の場合、片面印刷された本文用紙Ｐ１は、ベルト搬送部３５により搬送されつつ、連絡路７ｄの手前にある図示しない切替部により製本装置３へは行かずに周回路７ａへ導かれる。本文用紙Ｐ１は、排紙部６の手前にある図示しない切替部により反転路７ｃへ導かれ、一端停止してから反転するスイッチバックを行い、周回路７ａに戻る。その後、本文用紙Ｐ１は、印刷部５へ再給紙される。ここで、本文用紙Ｐ１は、反転路７ｃで反転されているので、未印刷面がインクジェットヘッド５ｃに向けられている。本文用紙Ｐ１は、ベルト搬送部３５により搬送されつつ、インクジェットヘッド５ｃから吐出されるインクにより未印刷面が印刷され、上述した片面印刷の場合と同様に、連絡路７ｄから製本装置３へ送り出される。 In the case of double-sided printing, the text sheet P1 printed on one side is guided to the peripheral circuit 7a by the switching unit (not shown) in front of the communication path 7d without going to the bookbinding device 3 while being transported by the belt transport unit 35. The text sheet P1 is guided to the reversing path 7c by a switching unit (not shown) in front of the paper discharge unit 6, and is switched back after being stopped at one end and returned to the peripheral circuit 7a. Thereafter, the text sheet P1 is fed again to the printing unit 5. Here, since the text sheet P1 is reversed by the reversing path 7c, the unprinted surface is directed to the inkjet head 5c. The body sheet P1 is conveyed by the belt conveyance unit 35, the unprinted surface is printed by the ink ejected from the inkjet head 5c, and is sent to the bookbinding apparatus 3 from the communication path 7d as in the case of the single-sided printing described above. .

印刷装置２では、１冊分の複数の本文用紙Ｐ１が順次印刷され、続いて、表紙用紙Ｐ２が印刷される。表紙用紙Ｐ２は、外部給紙台４ａから給紙され、上述した本文用紙Ｐ１の場合と同様に、片面印刷または両面印刷される。そして、印刷済みの表紙用紙Ｐ２は、連絡路７ｄから製本装置３へ送り出される。 In the printing apparatus 2, a plurality of body sheets P1 for one book are sequentially printed, and then a cover sheet P2 is printed. The cover sheet P2 is fed from the external sheet feed stand 4a and is printed on one side or both sides as in the case of the body sheet P1 described above. Then, the printed cover sheet P2 is sent out to the bookbinding apparatus 3 from the communication path 7d.

次に、製本装置３の製本動作について図５〜図８を参照して説明する。
ここで、図５においてかっこ付き数字（１）〜（５）を付した部分は、以下に示す各工程の番号（１）〜（５）において説明した内容に対応し、図６においてかっこ付き数字（６）〜（９）を付した部分は、以下に示す各工程の番号（６）〜（９）において説明した内容に対応する部分である。 Next, the bookbinding operation of the bookbinding apparatus 3 will be described with reference to FIGS.
Here, in FIG. 5, the parts with parenthesized numerals (1) to (5) correspond to the contents described in the numbers (1) to (5) of the respective steps shown below, and the numerals with parentheses in FIG. The part which attached | subjected (6)-(9) is a part corresponding to the content demonstrated in number (6)-(9) of each process shown below.

（１）製本システム１が製本印刷動作を開始し、印刷装置２から製本装置３に印刷済みの用紙が送られ、本文用紙Ｐ１の貯留エリアである整合部（構成は図示せず）に本文用紙Ｐ１が積載・貯留され、用紙束ＰＳが形成されていく。 (1) The bookbinding system 1 starts a bookbinding printing operation, a printed sheet is sent from the printing apparatus 2 to the bookbinding apparatus 3, and a text sheet is sent to an alignment unit (configuration not shown) that is a storage area for the text sheet P1. P1 is loaded and stored, and a sheet bundle PS is formed.

（２）本文用紙Ｐ１の印刷が終了すると、表紙用紙Ｐ２が印刷され、表紙待機位置である成形部１４に搬入され、待機する。この表紙用紙Ｐ２は、その長手方向の中央に用紙束ＰＳの背を当接させてくるみ綴じした場合、用紙束ＰＳの小口ＰＳｂから両端部Ｅが均等に突出するような寸法の用紙である。ここで、表紙用紙Ｐ２は、用紙センサ２２の検出信号とエンコーダの検出信号に基づいて位置を管理しながら表紙搬入ローラ２１で搬送され、一対の背折りプレート２３，２３の中央部に対し、搬送方向の中央部分で位置決めされる。 (2) When the printing of the text sheet P1 is completed, the cover sheet P2 is printed and is carried into the molding unit 14 which is the cover standby position, and waits. This cover sheet P2 is a sheet having a size such that both ends E protrude evenly from the small edge PSb of the sheet bundle PS when the back of the sheet bundle PS is brought into contact with the center in the longitudinal direction. Here, the cover sheet P2 is conveyed by the cover sheet carry-in roller 21 while managing the position based on the detection signal of the sheet sensor 22 and the detection signal of the encoder, and is conveyed to the central portion of the pair of back folding plates 23 and 23. Positioned in the central part of the direction.

（３）用紙束ＰＳはクランプ部１２に挟まれて接着剤塗布部１３に移動し、用紙束ＰＳの端面（背）ＰＳａを塗布ローラ１４ｂに接触させる。塗布ローラ１４ｂが回転し、収容部１４ａに収容されたホットメルト接着剤Ｇを用紙束ＰＳの端面ＰＳａに付着させる。 (3) The sheet bundle PS is sandwiched between the clamp portions 12 and moves to the adhesive application unit 13 to bring the end face (back) PSa of the sheet bundle PS into contact with the application roller 14b. The application roller 14b rotates to adhere the hot melt adhesive G accommodated in the accommodation portion 14a to the end surface PSa of the sheet bundle PS.

（４）保持された糊付けされた用紙束ＰＳを、クランプ部１２で挟んだまま、冊子成形手段である成形部１４に移動させる。一対の背折りプレート２３，２３の上に配置した表紙用紙Ｐ２の上から、ホットメルト接着剤Ｇが塗布された用紙束ＰＳの端面ＰＳａを当接させ、一対の背折りプレート２３，２３を接近する方向に駆動して用紙束ＰＳを挟み込む。用紙束ＰＳを表紙用紙Ｐ２でくるみ綴じした冊子Ｂが成形される。 (4) The held glued sheet bundle PS is moved to the forming section 14 which is a booklet forming means while being sandwiched between the clamp sections 12. The end surface PSa of the sheet bundle PS to which the hot melt adhesive G is applied is brought into contact with the cover sheet P2 disposed on the pair of backfold plates 23, 23, and the pair of backfold plates 23, 23 are brought close to each other. To drive the sheet bundle PS. A booklet B in which the sheet bundle PS is bound and bound with the cover sheet P2 is formed.

（５）成形された冊子Ｂを、背を下とし小口ＰＳｂを上にした姿勢で、表紙折筋加工部１５の第１の折筋加工ローラ３０に挿入し、第２の折筋加工ローラ３０と共に連続的に搬送する。第１折筋加工ローラ３０及び第２折筋加工ローラ３０の各ローラ対の間隔は、用紙束ＰＳの間隔よりも若干小さめとなるように自動的に設定されている。従って、各折筋加工ローラ３０が、用紙束ＰＳを挟持搬送すると、弾性材料で構成された各折筋加工ローラ３０は若干潰れ、冊子Ｂはプレスされた状態となる。従って、表紙用紙Ｐ２の端部Ｅは用紙束ＰＳの小口ＰＳｂの端辺に押し付けられ、表紙用紙Ｐ２の両端には折筋Ｆが加工される。 (5) The formed booklet B is inserted into the first folding line processing roller 30 of the cover folding line processing unit 15 in a posture with the back facing down and the fore edge PSb facing up, and the second folding line processing roller 30 Conveys continuously. The interval between each pair of the first folding line processing roller 30 and the second folding line processing roller 30 is automatically set to be slightly smaller than the interval of the sheet bundle PS. Therefore, when each folding line processing roller 30 pinches and conveys the sheet bundle PS, each folding line processing roller 30 made of an elastic material is slightly crushed and the booklet B is pressed. Accordingly, the edge E of the cover sheet P2 is pressed against the edge of the small edge PSb of the sheet bundle PS, and the folding lines F are processed at both ends of the cover sheet P2.

（６）第２折筋加工ローラ３０に受け渡された冊子Ｂは下方に搬送され、小口ＰＳｂが第２折筋加工ローラ３０を通過する際に表紙の端部Ｅに折筋Ｆが付けられる。表紙折筋加工部１５から冊子Ｂが排出される際、少なくとも冊子Ｂの背が表紙折り加工部１６ａのベルト搬送部３５に接する際には、ベルト搬送部３５は左方に向けて移動しており、これによって冊子Ｂは右に向けて倒れ、小口ＰＳｂが次段の加工部である表紙折り加工部１６ａの表紙突き当て部材３６に向く。 (6) The booklet B delivered to the second folding line processing roller 30 is conveyed downward, and the folding line F is attached to the end E of the cover when the fore edge PSb passes through the second folding line processing roller 30. . When the booklet B is ejected from the cover folding line processing unit 15, at least when the back of the booklet B comes into contact with the belt conveyance unit 35 of the cover folding unit 16a, the belt conveyance unit 35 moves to the left. As a result, the booklet B falls to the right, and the fore edge PSb faces the cover sheet abutting member 36 of the cover folding section 16a, which is the processing section of the next stage.

（７）用紙束ＰＳの小口ＰＳｂから突出している表紙用紙Ｐ２の両端部Ｅのうち、一方の端部Ｅの折り加工を行う。この表紙折り加工工程については、上記（６）で説明した工程の一部も含め、以下に図７を参照して作用を詳細に説明する。
図７（ａ），（ｂ）に示すように、冊子Ｂが、表紙折筋加工部１５から、下方の表紙折り加工部１６ａのベルト搬送部３５に排出される際、少なくとも冊子Ｂの背がベルト搬送部３５に接するまでに、ベルト搬送部３５は左方に向けて移動している。これにより、ベルト搬送部３５に接した冊子Ｂはベルトに接した背側を左方に持っていかれ、上方にある小口ＰＳｂが右方に倒れるため、小口ＰＳｂが第１の表紙折り加工部１６ａの表紙突き当て部材３６に向く。 (7) One end E of the both ends E of the cover sheet P2 protruding from the edge PSb of the sheet bundle PS is folded. This cover folding process, including part of the process described in (6) above, will be described in detail below with reference to FIG.
As shown in FIGS. 7A and 7B, when the booklet B is ejected from the cover folding part processing unit 15 to the belt conveying unit 35 of the lower cover folding part 16a, at least the back of the booklet B is By contact with the belt conveyance unit 35, the belt conveyance unit 35 has moved leftward. As a result, the booklet B in contact with the belt conveyance unit 35 is held with the back side in contact with the belt to the left, and the upper edge PSb falls to the right, so the edge PSb becomes the first cover folding section 16a. It faces the cover sheet abutting member 36.

図７（ｃ）に示すように、ベルト搬送部３５を逆転し、冊子Ｂを、右方にある第１の表紙折り加工部１６ａの表紙突き当て部材３６に向けて搬送する。表紙用紙Ｐ２の一方の端部Ｅは、上ガイド板３６ａ及び下ガイド板３６ｂに案内されて突き当て部３６ｃに突き当たる。 As shown in FIG. 7C, the belt conveyance unit 35 is reversed, and the booklet B is conveyed toward the cover sheet abutting member 36 of the first cover sheet folding unit 16a on the right side. One end E of the cover sheet P2 is guided by the upper guide plate 36a and the lower guide plate 36b and abuts against the abutting portion 36c.

図７（ｄ）に示すように、冊子Ｂをさらに同方向に搬送することにより、表紙用紙Ｐ２の一方の端部Ｅの折筋Ｆが表紙折りローラ３７の側に撓み、巻き込まれる。なお、このとき、表紙用紙Ｐ２の一方の端部Ｅの折筋Ｆが表紙折りローラ３７に巻き込まれやすいように、駆動ローラ３７ａよりも従動ローラ３７ｂの位置をやや高めに設定しておき、折筋Ｆをニップしやすいようにしてもよい。 As shown in FIG. 7D, by further transporting the booklet B in the same direction, the folding line F at one end E of the cover sheet P2 is bent and wound around the cover folding roller 37 side. At this time, the position of the driven roller 37b is set slightly higher than the driving roller 37a so that the folding line F at one end E of the cover sheet P2 is easily caught in the cover sheet folding roller 37. The streak F may be easily nipped.

図７（ｅ）に示すように、前述した表紙折返し長さＬ（図３参照）だけ同方向に搬送し、表紙用紙Ｐ２の端部Ｅの略全長を表紙折りローラ３７に挟み込む。このとき、用紙束ＰＳも表紙折り加工部１６ａに入り込んでくるが、下ガイド板３６ｂは下方に揺動するので用紙束ＰＳを下方に逃すことができる。 As shown in FIG. 7 (e), the above-described cover folding length L (see FIG. 3) is conveyed in the same direction, and the substantially entire length of the end E of the cover sheet P 2 is sandwiched between the cover folding rollers 37. At this time, the sheet bundle PS also enters the cover folding section 16a, but the lower guide plate 36b swings downward so that the sheet bundle PS can be released downward.

図７（ｆ）に示すように、表紙折りローラ３７を全体として微小な所定距離だけ上方へ退避させ、続いてベルト搬送部３５及び表紙折りローラ３７を逆転させる。表紙折りローラ３７を上方へ移動したため、駆動ローラ３７ａは従動ローラ３７ｂよりも位置が高くなっており、これら表紙折りローラ３７から排出される表紙用紙Ｐ２はベルト搬送部３５と同様に図中左方に向かうようになっており、このため折り返した表紙用紙Ｐ２の端部Ｅが表紙折り加工部１６ａの方向に進んで開いてしまうことはない。 As shown in FIG. 7F, the cover folding roller 37 as a whole is retreated upward by a minute predetermined distance, and then the belt conveyance unit 35 and the cover folding roller 37 are reversed. Since the cover folding roller 37 has been moved upward, the drive roller 37a is positioned higher than the driven roller 37b, and the cover sheet P2 discharged from the cover folding roller 37 is on the left side of the figure in the same manner as the belt conveyance unit 35. Therefore, the end E of the folded cover sheet P2 does not advance toward the cover folding section 16a and open.

図７（ｇ）に示すように、表紙用紙Ｐ２の端部Ｅが表紙折りローラ３７から抜けると、表紙用紙Ｐ２の一端部Ｅは折筋Ｆで折り返され、表紙用紙Ｐ２と用紙束ＰＳの間に折り込まれた状態となる。これで表紙用紙Ｐ２の一方の端部Ｅの表紙折り加工は完了し、冊子Ｂを第２の表紙折り加工部１６ｂへ移動する。 As shown in FIG. 7G, when the end E of the cover sheet P2 comes off the cover folding roller 37, the one end E of the cover sheet P2 is folded at the folding line F, and between the cover sheet P2 and the sheet bundle PS. It will be in the state folded in. This completes the cover folding process of one end E of the cover sheet P2, and moves the booklet B to the second cover folding process unit 16b.

図示はしないが、第２の表紙折り加工部１６ｂにおける表紙折り加工は、上述した第１の表紙折り加工部１６ａでの加工と略同一である。これにより、表紙用紙Ｐ２を切断することなく、用紙束ＰＳと表紙用紙Ｐ２との不揃いがない整然とした小口ＰＳｂを有する冊子Ｂが得られる。図示しないが、冊子搬送コンベア４０を回転し、筐体９の外側の受取台４１に完成した冊子Ｂを排出する。 Although not shown, the cover folding process in the second cover folding unit 16b is substantially the same as the process in the first cover folding unit 16a described above. As a result, the booklet B having an orderly small edge PSb in which there is no unevenness between the sheet bundle PS and the cover sheet P2 is obtained without cutting the cover sheet P2. Although not shown, the booklet transport conveyor 40 is rotated, and the completed booklet B is discharged to the receiving table 41 outside the housing 9.

以上説明した第１実施形態の製本システム１が備える製本装置３によれば、用紙束ＰＳの小口ＰＳｂから表紙用紙Ｐ２の端部Ｅが突出している状態で、この用紙束ＰＳを折筋加工ローラ３０に通してプレスし、用紙束ＰＳの小口ＰＳｂから突出している表紙用紙Ｐ１の端部Ｅを用紙束ＰＳの小口ＰＳｂの端辺に押し付けて、表紙用紙Ｐ１の端部Ｅに折筋Ｆを形成できる。さらに、この用紙束ＰＳを表紙折り加工部１６ａ，１６ｂに送り、表紙用紙Ｐ１の端部Ｅを折筋Ｆに沿って表紙用紙Ｐ１の裏側に折り込むことができる。このため、表紙用紙Ｐ１を用紙束ＰＳに合わせて切断することなく、図８に示すように、用紙束ＰＳの小口ＰＳｂの２つの端辺と、この用紙束ＰＳをくるむ表紙用紙Ｐ２の小口ＰＳｂに近い２つの端辺とを一致させて、見栄えに優れた装丁の質感の高い高品質な冊子Ｂを製作することができる。 According to the bookbinding apparatus 3 included in the bookbinding system 1 according to the first embodiment described above, the sheet bundle PS is folded into a folding roller in a state where the end E of the cover sheet P2 protrudes from the small edge PSb of the sheet bundle PS. 30 and presses the edge E of the cover sheet P1 protruding from the edge PSb of the sheet bundle PS against the edge of the edge PSb of the sheet bundle PS, so that the folding line F is formed at the edge E of the cover sheet P1. Can be formed. Further, the sheet bundle PS can be sent to the cover folding sections 16a and 16b, and the end E of the cover sheet P1 can be folded along the folding line F to the back side of the cover sheet P1. Therefore, without cutting the cover sheet P1 in accordance with the sheet bundle PS, as shown in FIG. 8, the two edges of the fore edge PSb of the sheet bundle PS and the fore edge PSb of the cover sheet P2 that encloses the sheet bundle PS. By aligning the two edges close to each other, it is possible to produce a high-quality booklet B with a high-quality texture of the binding.

第２実施形態の製本システム１の製本装置３について図９を参照して説明する。
本実施形態は、第１実施形態の製本装置３において、第１の表紙折り加工部１６ａと第２の表紙折り加工部１６ｂの間に搬送ガイド５０を設けたことを特徴とするものであり、その他の構成は第１実施形態と同一である。 The bookbinding apparatus 3 of the bookbinding system 1 according to the second embodiment will be described with reference to FIG.
The present embodiment is characterized in that, in the bookbinding apparatus 3 of the first embodiment, a conveyance guide 50 is provided between the first cover sheet folding unit 16a and the second cover sheet folding unit 16b. Other configurations are the same as those of the first embodiment.

搬送ガイド５０は、第１の表紙折り加工部１６ａのベルト搬送部３５の左端部の左方に、所定間隔をおいて配置されており、下方にある第２の表紙折り加工部１６ｂのベルト搬送部３５の略中央に冊子Ｂを誘導する湾曲した案内面を備えている。 The conveyance guide 50 is disposed at a predetermined interval to the left of the left end portion of the belt conveyance section 35 of the first cover folding section 16a, and the belt conveyance of the second cover folding section 16b located below. A curved guide surface for guiding the booklet B is provided in the approximate center of the portion 35.

第１の表紙折り加工部１６ａにおいて表紙用紙Ｐ２の片側の端部Ｅを折り加工した後、ベルト搬送部３５は左に駆動し、冊子Ｂは搬送ガイド５０に沿って搬送され、第２の表紙折り加工部１６ｂのベルト搬送部３５の上に背から着地する。そして、第２の表紙折り加工部１６ｂのベルト搬送部３５は、冊子Ｂの表紙用紙Ｐ２の他方の端部Ｅが、第２の表紙折り加工部１６ｂの表紙突き当部材３６に向くように、ベルト搬送部３５を右方に駆動する。表紙用紙Ｐ２の未加工の他方の端部Ｅが、第２の表紙折り加工部１６ｂの表紙突き当部材３６に向いた後、ベルト搬送部３５を右方に駆動し、第１の表紙折り加工部１６ａでの工程と同様の作業を行い、未処理の他方の端部Ｅも表紙裏に折り込む。 After the end E on one side of the cover sheet P2 is folded in the first cover folding section 16a, the belt transport section 35 is driven to the left, and the booklet B is transported along the transport guide 50, and the second cover sheet. Land on the belt conveying unit 35 of the folding unit 16b from the back. Then, the belt conveying section 35 of the second cover folding section 16b is arranged so that the other end E of the cover sheet P2 of the booklet B faces the cover abutting member 36 of the second cover folding section 16b. The belt conveyance unit 35 is driven rightward. After the other unprocessed end E of the cover sheet P2 faces the cover sheet abutting member 36 of the second cover sheet folding section 16b, the belt conveying section 35 is driven to the right, and the first cover sheet folding process is performed. The same operation as the process in the section 16a is performed, and the other unprocessed end E is folded into the back cover.

第２実施形態によれば、搬送ガイド５０があるため、第１の表紙折り加工部１６ａから第２の表紙折り加工部１６ｂに冊子Ｂが移行する際、冊子Ｂの姿勢を安定化することができるため、同移行時、何らかの理由で冊子Ｂがバランスを崩して向きにばらつきが生じ、第２の表紙折り加工部１６ｂでの加工ができなくなる可能性を減少させることができる。 According to the second embodiment, since the conveyance guide 50 is provided, the posture of the booklet B can be stabilized when the booklet B moves from the first cover-sheet folding unit 16a to the second cover-sheet folding unit 16b. Therefore, at the time of the transition, it is possible to reduce the possibility that the booklet B loses its balance for some reason and the orientation varies and the processing at the second cover folding section 16b cannot be performed.

本発明は前述した実施形態のみに限定されるものではなく、実施段階ではその要旨を逸脱しない範囲で構成要素を種々に変形して具体化することができる。例えば、実施形態では、表紙折筋加工部１５を、第１の折筋加工ローラ３０及び第２の折筋加工ローラ３０の２段２対のローラで構成したが、１段１対の折筋加工ローラ３０でもよい。また、表紙折り加工部１６は２基設けて表紙用紙Ｐ２の各端部Ｅを順次折り加工するものとしたが、用紙束ＰＳの小口ＰＳｂから突出した表紙用紙Ｐ２の両端部Ｅを各折筋Ｆで折り加工できるものであれば、一基でもかまわない。また、本発明は、上記実施形態に開示された複数の構成要素の適宜な組み合せにより、本発明の様々なバリエーションを形成できる。例えば、実施形態に示される全構成要素から幾つかの構成要素を削除してもよい。 The present invention is not limited only to the above-described embodiments, and can be embodied by variously modifying the components without departing from the scope of the invention in the implementation stage. For example, in the embodiment, the cover sheet folding line processing unit 15 is configured by two pairs of two rollers, the first folding line processing roller 30 and the second folding line processing roller 30, but one pair of folding lines. The processing roller 30 may be used. In addition, two cover folding sections 16 are provided to sequentially fold each end E of the cover sheet P2, but each end E of the cover sheet P2 protruding from the small edge PSb of the sheet bundle PS is folded into each folding line.
