Further, the paper P fixed by the fixing device 13 is taken into the reversal path 14 via the branching claw B, and the front and back of the paper P can be reversed by ejecting the paper P with the front and back in the transport direction reversed.

In the present embodiment, a digital copying machine will be described as an example of the recording apparatus, but it can be applied to other recording apparatuses such as an analog copying machine, a facsimile machine, a printer, etc. instead. The bookbinding machine 4 may not only be connected to the copying machine online as in the present embodiment, but may also be constructed offline.

The bookbinding machine 4 is connected to the paper discharge port of this copying machine, and when the bookbinding is not performed, the paper P is a branch claw C.
The sheet is guided upward by and is discharged onto the sheet discharge tray 41 as it is. On the other hand, in the case of bookbinding, the paper P is guided downward by the branching claw C, and is then guided between the staple tray 42 and the guide member 42a, which are inclined so that the left side of the drawing is upward, Staple tray 4
Stacked on 2. Then, the staple tray 42
The paper P discharged upward is lowered by gravity and the brush roller 43, and its lower end abuts the reference member 44 and stops. Although not shown, a jogger for aligning the bundle of sheets P in the width direction (direction orthogonal to the drawing) is provided,
The jogger and the reference member 44 stack the stack of sheets P at a predetermined position in a stacked state.

The reference member 44 is movable along the conveyance direction of the paper P, moves to the stack (end) position in the case of side stitching (end binding), and moves in the case of saddle stitching (center binding). Moves to the center position according to the size of the paper P, and at this position, stapling is performed by the known stapler 45 from the upper surface side of the stack of sheets stacked on the staple tray 42. The sheet P after stapling is conveyed upward along the inclined surface of the staple tray 42 and discharged onto the sheet discharge tray 41 in the case of flat binding in which no tape is attached. In order to ensure the binding, it is desirable that the stapler 45 has two or more continuous staplers for simultaneously driving a plurality of staples.

In the bookbinding mode in which the staple driving side surface is convex, the staple driving side surface is convex by the first folding device such as the first folding roller pair 46a provided in the middle of the staple tray 42. And is discharged through the path 47 in the form of so-called saddle stitch binding. In the folding in this case, when the central portion of the sheet reaches the folding roller 46a, the leading end abuts on the stop member 49a of the first folding stopper 49 that moves in the transport direction according to the sheet size by the motor M12, and the rear end side By being pushed by the conveyor belt, the central portion is bent and gripped by the nip portion of the folding roller pair 46a.
This is done by proceeding to 7.

When the tape for the back cover is applied, the sheet bundle on the staple tray 42 is switched back and is directed toward the branch claw F by the branch claw E, and in the case of flat stitching, the branch claw E is used. , F, the stapled paper P is guided to the path 48, the front end thereof is taped by the back tape bonding portion 50, and the tape is bent into a U-shape by the folding portion 50b.

In the bookbinding mode in which the surface of the staple driving side is concave, the leading edge of the sheet bundle advances toward the second folding stopper 49b by the branch claw F and comes into contact therewith, and the trailing edge side is pushed by the conveyor belt. As a result, the center portion is bent and is folded in two by the nip portion of the second folding roller 46b so that the surface on the driving side is concave, and the back tape attaching portion 50 is attached to the binding portion where the needle tip is exposed. The cover is pasted. Similarly, the second folding stopper 49b is moved and stopped by the motor M13 according to the sheet size so that the leading end of the second folding stopper 49b contacts when the center of the sheet bundle P reaches the second folding roller 46b. .

As shown in FIG. 2 and FIG. 3, the back surface tape attaching section 50 has an adhesive tape T in the width direction of the sheet bundle P with respect to one end of the sheet bundle P on the front side or the back cover side.
Of the spine cover and the other side of the front cover side or the back cover side so as to stick out so as to stick out in the traveling direction, and the protruding tape T as shown in FIG. It has a tape folding section 50b that folds to the front end surface) and then folds to the opposite side of the paper P attachment surface.

Next, the detailed structure of the tape attaching section 50a will be described with reference to FIGS. As shown in FIG. 5, the front end of the sheet bundle P is conveyed to the attaching position by the sheet holding surface of the sheet holding member 51 and the roller pair 52. The sheet holding member 51 is arranged on the side opposite to the pasting surface, and the sheet holding member 51 and the roller pair 52 constitute a sheet holding means for holding the sheet bundle P on the tape attaching section 50a.

The tape adhering portion 50a is retracted from the conveying path of the paper bundle P as shown by the alternate long and short dash line about the rotation center 58 as the paper advancing portion and the standby state, and the tape adhering portion 50a. The leaf spring 53 on the side elastically abuts the fixed stopper 54. Then, when the sheet bundle P stops at the attaching position, the tape attaching portion 50a is rotated by the solenoid 65 to the position indicated by the solid line in the figure.

The tape cartridge 55 is preliminarily provided with a tape T wound around a roll so that its adhesive surface faces the sheet bundle P, and is provided with a tape guide portion 55a. The tape cartridge 55 is held by a holder 56, and the holder 56 is supported rotatably around a shaft 58 with respect to a tape carrier 57, as shown in FIG. 4, and when the motor M1 rotates, the sector gear 59 and the pinion 60. Is rotated so that the tape T is separated by the cutter 61. Also, the tape carrier 5
7 is supported by a bracket 62a and a feed screw 62b so as to be movable in the width direction of the sheet bundle P.
As shown in FIG. 5, b is connected to the motor M2 via a timing pulley 63 and a timing belt 64.
In addition, a member 6 that presses the sheet bundle P is attached to the bracket 62a.
2c is formed. In this case, the tape attaching part 5
0a is the pasting position, and the width direction of the tape T is shown in FIG.
4A and 5A, when the sheet bundle P is attached so as to protrude from the front end of the sheet bundle P as shown in FIG.
The free end of the tape T is pressed against the sheet bundle P as shown in FIG. When the tape cartridge 55 moves in the width direction of the sheet bundle P while maintaining this state, the tape T is attached in the width direction while protruding from the tip of the sheet bundle P. When the tape T is attached in the width direction of the sheet bundle P, the tape cartridge 55 stops moving, and
The tape T is cut when it is rotated as shown in FIG. The rotation position of the tape cartridge 55 is determined by the stopper 66.

When the tape application is completed, as shown in FIGS. 3 and 6, the protruding portion (T1 in the figure) of the tape T in the direction away from the roller pairs 71a and 71b goes over the first roller 71a. Roller pair 72 to position
And is stopped by being conveyed by the motor M6. At this stop position, a guide member 73 for guiding the tape attachment surface side of the sheet bundle P and a pressing member 74 for pressing the opposite surface are arranged.

The guide member 73 and the pressing member 74 are both rotatable around a shaft 75, and the pressing member 74
Guides the sheet bundle P by retracting to the position of the stopper 77,
When pressed by the solenoid 76 to rotate and contact the pin 73a of the guide member 73, the guide member 73 and the pressing member 74
Bends the leading end of the sheet bundle P to the nip portion of the roller pair 71a, 71b, so that the protruding portion T of the tape T
1 is folded along the spine surface of the sheet bundle P by 90 ° (see FIG. 3).
The protruding portion T2). In addition, in FIG. 3, the motor M3 is shown to be rotatable, but either may be used. Also,
A cushioning spring 74a is attached to the pressing member 74.

Next, when the motors M6 and M7 are driven and the leading edge of the sheet bundle P is gripped in the nip portion of the roller pair 71a and 71b, the protruding portion T2 of the tape T is further folded to the opposite side of the sheet bundle P. Rarely, it is folded into a U-shape (T3 in the figure) as shown in FIG.

Here, the tape folding section 50 shown in FIG.
In the first folding step of b, the pressing member 74 presses the sheet bundle P against the second roller 71b, so that the position of the sheet bundle P with respect to the nip portion can be stabilized. Further, in the second folding process, the strong conveyance force can be applied to the leading end of the sheet bundle P by driving the second roller 71b, so that the sheet bundle P can be gripped more surely in the nip portion.

Further, in the process of transporting from the sticking position to the folding position, if the protruding portion T1 of the sheet bundle P or the tape T has a curl, the roller 7 close to the path is formed.
1b and further deformed, or roller pair 71a, 7
The position with respect to 1b may be defective and the folding of the tape T may be incomplete. Therefore, as shown in FIG. 6, by providing the guide member 73 between the roller pairs 71a and 71b and the radial path, the progress of the sheet bundle P can be stabilized and positioned. Further, since the guide member 73 is pushed and displaced by the sheet bundle P when being pushed, it does not interfere with folding.

In FIG. 6, roller pairs 71a and 71a
Although b is configured so as not to intersect with the extension surface of the tape attachment surface of the sheet bundle P, the tip of the sheet bundle P is curved by arranging it by appropriately setting the shape and position of the guide member 73. The degree of freedom can be improved.

In the vicinity of the sheet bundle P to which the tape T is attached and folded, the flatness may be low due to pre-binding such as stapling, gluing, thread binding, and wavy curling due to moisture absorption and moisture release. . For this purpose, the roller pair 7
By configuring at least one of 1a and 71b with an elastic body such as rubber or foam material, it is possible to reduce the variation in the above-mentioned pasting and folding regions, and to realize tape pasting without sticking defects or peeling. it can.

When the staple is performed by the side-stitching, the pressure contact force with respect to the roller 71a becomes non-uniform during the first folding in which the needle is pressed by the pressing member 74, or the second folding is performed. At this time, when the sheet bundle P advances, a problem such as a needle being caught occurs. Therefore, as shown in FIG. 7, by forming a notch 74a or a depression at the position of the pressing member 74 corresponding to the staple S binding the bundle of sheets P, the above problem is eliminated and stable folding of the tape T is performed. be able to.

Next, another tape attaching section 80 will be described with reference to FIGS. In this example, FIG.
, The free end of the tape T is gripped by the roller pair 81a, 81b, and the roller pair 81a, 81b
11, the axial length of the roller pair 81a on the pressing side is slightly longer than the width of the tape T, and the axial length of the roller pair 81b on the adhesive surface side of the tape T is the protrusion of the tape T. It is configured to substantially match the minutes.

The roller pairs 81a and 81b are constituted by unidirectional roller clutches, and are mounted on a tape gripping unit 80a as shown in FIG. As shown in FIG. 10, the tape gripping unit 80a is configured to be movable in the width direction of the sheet bundle P by the motor M4. Further, the tape cartridge 82 (see FIGS. 10 and 11) is configured to be movable in the width direction of the sheet bundle P by the motor M5. Therefore, when the tape gripping unit 80a moves, the tape T moves to the tape cartridge 82 (FIGS. 10 and 11). 11)). As shown in FIG. 10, the tape gripping unit 80a is also equipped with a solenoid 83 for moving the roller pair 81b on the adhesive surface side in the pressing direction or the releasing direction, and a tape cutter 84 for cutting the tape T. There is.

The operation of the tape gripping unit 80a will be described with reference to FIGS.
The leading end of the sheet holding surface of the sheet holding member 51 and the roller pair 52.
In the state where the sheet bundle P is conveyed to the pasting position, the tape is held from the conveying path of the sheet bundle P. Before the sheet bundle P reaches the pasting position, the solenoid 83 is turned on as shown in FIG. 80a moves to the tape application start position, and the tape cartridge 82 moves to the tape application end position. Therefore, the roller pair 81b on the adhesive surface side
Moves in the pressing direction, so that the tape T is pulled out from the tape cartridge 82 with tension by the roller pair 81a and 81b by a distance corresponding to the tape attachment.

When the bundle of sheets P stops at the pasting position, the solenoid 85 causes the tape gripping unit 80 to rotate to the pasting position where the tape T protrudes from the tip of the bundle of sheets P as shown in FIG. Then the solenoid 8
When the tape gripping unit 80a moves from the tape sticking start position to the tape sticking end position after the roller 3b is turned off and the adhesive surface side roller 81b rotates in the detaching direction, the tape T is pressed by the roller 81a and the paper When the tape gripping unit 80 is attached to the bundle P and reaches the tape attaching end position, the tape cutter 84 abuts on the holding member 86 of the tape cartridge 82 and rotates to cut the tape T.

Since the tape gripping unit 80a and the tape cartridge 82 move relative to each other when the tape T is unwound, only the tape cartridge 82 may be moved. Either one of the sheet bundles P may be conveyed first,
The above example performed in parallel is more efficient.

Here, in the above embodiment, the surface on the driving side of the staple is convex, that is, the bookbinding mode in which the staple is driven from the spine cover side and the needle tip is bent inside, and the surface on the driving side of the staple is concave, In the bookbinding mode, the front and back sides of the paper are reversed, but the back and front sides of the paper are reversed. Setting error can be prevented by displaying on.

Further, in the bookbinding machine connected to the copying machine online as in this embodiment, the page order can be properly arranged on the copying machine side. That is, N sheets of paper P
When binding 4N pages (including blank pages) with, the staple S is the cover in the bookbinding mode in which the staple S is driven in from the spine cover side and the staple tip is bent inward as shown in FIG. Since it is driven into the 4Nth page side, which is the back cover, the first 2Nth and (2N + 1) th pages (or the backside thereof, (2N-1) and (2N + 2) th pages) on which the needle tip protrudes. Recording is started from the original, and the sheets are stacked on the staple tray 42 so that the 2Nth and (2N + 1) th page sides are on the bottom, and finally the 1st and 4Nth page sides are on the staple tray 42. It

Therefore, in FIG. 1, when the stapled sheet bundle P is folded in two by the first folding roller 46a provided in the middle of the staple tray 42 so that the spine cover side is the outer side, The tip is inside.
When the (2N-1) th and (2N + 2) th pages are recorded first and the 2Nth and (2N + 1) th pages are recorded on the back, the branch claw B in the copying machine shown in FIG. The sheet P is turned upside down by the inversion path 14 and conveyed to the bookbinding machine 4.

On the other hand, in the bookbinding mode in which staples are driven in from the inside of the spine cover and the needle tips are bent at the spine cover side to form the spine cover as shown in FIG. 13, the staples are the innermost 2N and (2N + 1). Since the printing is performed on the page side, recording is first started from the first and fourth Nth page originals, and the sheets are stacked on the staple tray 42 so that the side faces down, and finally the 2Nth and (2N + 1) th page are the last. And is stacked on the staple tray 42 so as to be recorded on the upper side.

Therefore, in FIG. 1, when the stapled sheet bundle P is folded in two by the second folding roller 46b so that the spine cover side is the outer side, the staple tip is the outer side. Although FIG. 1 illustrates the case where the staples are driven from the upper surface side of the sheet bundle stacked on the staple tray 42, the page order is reversed in the configuration in which the staples are driven from the lower surface of the sheet bundle stacked on the staple tray 42. Of course,
