The sheet P conveyed into entrance section 10 is conveyed to horizontal conveyance section 20, or to vertical conveyance sections 30. When post-processing is not carried out for sheet P, or when punch processing or shift processing is carried out for sheet P, the sheet P is conveyed to the horizontal conveyance section 20.
The numeral 21 represents a post-process section that conducts punch processing and shift processing.
Sheet P is conveyed to vertical conveyance section 30 when folding process is conducted for the sheet P.
The folding process includes an occasion where folding process only is conducted for sheet P conveyed in from an image forming apparatus, and an occasion where a pamphlet is produced by interposing sheet P in folded sheet P.
In the present specification, a pamphlet means one shown in
To be more specific, a bundle of sheets wherein sheet P2 is interposed in the center-folded sheets P1 is a pamphlet. The sheet P2 is composed of a single sheet or plural sheets. Further, sheet P1 is folded on its center line in many cases, but it is sometimes folded at a location shifted from the center.
In the case of simple folding process, the sheet P which has been conveyed vertically is conveyed from vertical conveying section 40 to folding conveyance section 60 where the sheet P is ejected to sheet-ejection tray 23 from sheet-ejection roller 22 through horizontal conveyance section 20.
In the case of producing a pamphlet, sheet P1 to be folded is conveyed through vertical conveyance sections 30 and 40, to folding conveyance section 60 where the sheet P1 is stopped temporarily under the condition of preparation for folding.
Next, sheet P2 to be interposed is conveyed through vertical conveyance section 30, and through bypass conveying section 50, to join sheet P1 to be folded that is under suspension.
In the folding conveyance section 60, sheet P1 to be folded and sheet P2 to be interposed are conveyed together, to be ejected to sheet-ejection tray 23 by sheet-ejection roller 22 through horizontal conveyance section 20.

Folding process and pamphlet production will be described as follows, referring to
First, folding process will be described.
Sheet P1 to be folded is conveyed to folding conveyance section 60 from vertical conveying section 40 to travel upward, and it stops when its folding line arrives at an intermediate position between roller 601 and roller 602. In this conveyance step, as shown in
Further, in this stage, guide member G3 is in its retracted position where the upward traveling of sheet P1 is not disturbed.
The suspension of conveyance by the folding rollers 601 and 602 is conducted at the point of time that has passed, by a prescribed period of time, from the detection of a leading edge of the sheet by sheet sensor SE1 arranged at the upstream side of the folding roller. This prescribed period of time is determined by a size of the sheet and by a type of folding.
At the point of time when the folding line arrives at an intermediate position between the folding roller 601 and the folding roller 602, the folding roller 602 moves to come in pressure-contact with the folding roller 601, and guide member G3 rotates counterclockwise around the rotary shaft of pressure-contact roller 603 to move to the position,in
When the guide member G3 is under the condition shown in
Then, the folding rollers 601 and 602 rotate respectively in the directions of Y1 and Y2, to force the sheet P1 into nip N.
Owing to the continuation of rotation of the folding rollers 601 and 602, the folded sheet P1 is conveyed in the direction of arrow Z to be ejected to sheet-ejection tray 23 by sheet-ejection roller 22 through horizontal conveyance section 20.
In the processing to produce a pamphlet, sheet P1 is conveyed through the conveyance process described above, and the sheet P1 is stopped at the point of time when its folding line arrives at an intermediate position between the folding rollers 601 and 602.
Further, the guide member G3 moves to the position shown in
Owing to this movement, bypass conveying section 50 is formed and conveyance of sheet P2 to be interposed is made possible as shown in
Sheet P2 conveyed through vertical-conveying section 30 under this condition is conveyed to folding conveyance section 60 from bypass conveying section 50.
At the point of time when a leading edge of the sheet P2 arrives at sheet P1, the folding rollers 601 and 602 rotate respectively in the directions of arrow Y1 and arrow Y2, to fold sheet P1 and to interpose sheet P2 in sheet P1 simultaneously, thus, a pamphlet is produced.
The pamphlet is ejected to sheet-ejection tray 23 by sheet-ejection roller 22 through horizontal-conveyance section 20.
The suspension of conveyance of sheet P2 is conducted at the point of time that has passed, by a prescribed period of time, from the detection of a leading edge of the sheet by sheet-sensor SE2 arranged in the vicinity of an outlet of bypass conveying section 50, and the conveyance of the sheet P2 is stopped at the sheet timing when a leading edge of the sheet P2 hits the sheet P1 firmly.

In the image forming processes covering from image forming to post-processing shown in
Therefore, for example, when producing pamphlets each having four pages, pamphlets are produced through the processes wherein image forming apparatus A forms images for 1-4 pages to produce the first pamphlet, and then, the image forming apparatus A forms images for 1-4 pages to produce the second pamphlet.
In step S1, a sheet is conveyed from sheet supply section 6A.
An image is formed on a sheet in step S2, and the sheet on which the image is formed is ejected to post-processing apparatus B in step S3.
In step S4, a sheet is judged whether it is sheet P1 to be folded or sheet P2 to be interposed.
When the sheet is judged to be the sheet P1, it is conveyed to folding conveyance section 60 (step S5).
In step S6, the sheet P1 is stopped temporarily at the position of the folding conveyance section 60. This position of the stop is a position where the folding line of the sheet P1 has arrived at an intermediate position between folding roller 601 and folding roller 602.
The folding line is formed on the center line of sheet P1 in many cases, but it is formed at a position that is off the center line occasionally depending on a shape of a pamphlet to be produced.
In step S7, the sheet P1 is judged whether it is a sheet for simple folding, or it is a sheet to be folded for conduction of an interposition process.
When the sheet is one to be folded for conduction of an interposition process (step S7; YES), the sheet waits until completion of preparation for interposing in step S8.
The completion of preparation for interposing means a process of detecting a passage of a leading edge of sheet P2 which is interposed, by sensor SE2.
In step S9, a center-folding start timer is started, and at completion of the timer (step S10), post-processing is started (step S11).
A center-folding timer in steps S9 and S10 creates a period of time during which the sheet P2 to be interposed is cause to hit the sheet P1 to be center-folded firmly.
In step S12, the sheet P1 in which the sheet P2 is interposed is folded and is ejected to sheet-ejection tray 23.
When the sheet P1 is judged not to be a sheet to be folded for the interposition in step S7, the process moves from step S7 to step S11, so that folding process is conducted and ejection is carried out (S12).
When the sheet is judged not to be a sheet to be folded in step S4, the process moves to step S14, and the sheet is judged whether it is sheet P2 to be interposed or not.
When the sheet is judged to be sheet P2 to be interposed, the sheet P2 is conveyed toward folding conveyance section 60 (step S15) and is stopped before the folding conveyance section 60 (step S16).
In step S17, a judgment is made whether preparation for folding is completed or not and an interposing timer is started at step S18, and sheet P2 is conveyed after completion of the timer (step S18).
Completion of preparation for folding in step S17, means a step of detecting that a leading edge of sheet P1 to be folded has passed through sensor SE1.
Steps S17-S20 represent processes which form a counterpart to processes of steps S8-S11 for sheet P1, and owing to these processes, sheet P2 to be interposed hits sheet P1 to be folded while keeping a right position, and thereby, a pamphlet wherein sheet P1 and sheet P2 are overlapped each other under the right alignment is produced and is ejected to sheet-ejection tray 23.
Incidentally, a judgment in each of steps S4 and S14 is made in accordance with a sheet conveyance program in the course of producing a pamphlet.
