Description

[Detailed description of the invention] (Technical field) The present invention relates to a copying method for bookbinding.

[Prior art]

Conventionally, when copying multiple copies of multiple sheets of original, a sorter or T-aligner is used to align the pages of the copied sheets, and a stitcher or the like is used to stitch the edges of the sheets. was.

However, when resized paper such as △3.84 is edge-stitched, it takes up 4 pages of space when spread, making it difficult to store 1 page. In the case of large-sized paper, edge-stitched paper is sometimes folded in half at the center to reduce the space required for storage, but if you fold the paper all at once in this way, It also doesn't look good when stored, and the folding makes it difficult to see the information on the folded part when spread out.

By the way, in order to eliminate the defect mentioned in 1, after copying on the left and right pages of the paper, fold the paper in half in the center and make the crease, stack the prescribed number of papers and then bind them at the crease. Therefore, it is possible to make a booklet that can be spread open, but if the booklet is bound in this way, the booklet cannot be bound unless the paper size and the original FI size match, and the booklet must be turned horizontally after binding for landscape manuscripts. 4, it becomes difficult to see.

[Purpose of the invention]

In view of the above-mentioned points, the present invention has been devised to make a booklet that can be stored and viewed without bulking up when it is bound after copying, and that can be viewed without changing the direction of the booklet. “The purpose is to provide h-methods.

(Structure of the invention) The embodiments of the present invention will be described above with reference to the drawings.

Further, a pair of sponge rods 051, 51 are disposed at the tip of the passage 50, and a passage 52 is further formed at the tip side of the sponge rods 051, 51. Further, a sensor 53 for detecting the presence or absence of paper P is disposed on the side of the passage 52.
When the paper P is detected, the o-roller 49 rotates once in the direction of the arrow. A stopper 54 that can rotate around a shaft 54a and take a retracted position faces inside the passage 52 on the downstream side of the sensor 53, and a pair of conveyance rollers 55, 55 are provided at the tip of the passage 52. is installed. A plurality of stoppers 54 may be provided according to the size of the paper P, or they may be movable according to the size of the paper P being used.

The sponge rollers 51, 51 serve to press the paper so that only the central portion of the paper P is bent toward the joint between the rollers 47, 49 when the leading edge of the paper P is in contact with the stopper 54. material, the conveyance force is weak,
Moreover, the circumferential speed of the sponge roller is 51.51 on both days - 47.
It is desirable that the circumferential speed be a little faster than the circumferential speed of 48. Further, a plurality of sponges (=1051.51) may be provided depending on the size of the paper P.

A non-binding tray 56 is disposed in the casing 44 on the downstream side of the conveyance rollers 55, 55, and is rotatable about a shaft 56a between the solid line position and the dashed line position in FIG. This non-binding tray 56 receives unfolded sheets P that do not need to be bound from the paper folding section 45 at the chain line position, and also receives sheets P to be bound from the paper folding section 45.
When it is transported, it rises to the solid line position and retreats 'C.

A paper binding section 57 is provided in the casing 44 below the non-binding tray 56.

The paper binding unit 57 is arranged to be movable up and down, and includes a binding tool 58 such as a stapler that binds the sheets of paper P using a stopper such as a stable, and a seat 59 arranged below the binding tool 58. The receiving surface 60 at the upper end of the seat 59 is used to hold the paper P whose center part has been folded by the paper folding section 45.
It is formed into an acute edge shape so that the folds of the sheets P can be stacked one on top of the other with the folds aligned. J, ta,
On both sides of the receiver seat 590, there is a pair of flat guide plates 63, 64 which are rotatably supported by the support shafts 61, 62, which are located near the receivers 60 of the U seat 59, respectively. The guide plates 63 and 64 are movable between the solid line position and the chain line position 4 in FIG.

On one side of the guide plate 64, there is a wall plate 65 that can be moved in the direction of the arrow depending on the paper size, as shown in FIG.
is erected, and a wall plate 66 movable in a direction orthogonal to the axial direction of the support shaft 62 is erected at the tip of the guide plate 64. This configuration is achieved by forming the base of the wall plate 66 and the guide plate 64 into a comb-teeth shape that engages with each other. Note that this wall plate 66 can take a retracted position as shown by the chain line in FIG. Further, on the outside of the wall plate 65, there are width adjusting rollers that roll in pressure contact with the paper P on the guide plate 64 and bring the two adjacent sides of the paper P into contact with both wall plates 65 and 66. 6
7 is provided protrudingly.

The axis of this offset roller 67 is arranged to intersect with the axis of the support shaft 62, and the offset roller 67
can move toward and away from the paper P on the guide plate 64.

A tray 68 is disposed below the guide plate 64, as shown in detail in FIG. They are facing each other with five. And this angle surface θ
1. By setting θ2 at an appropriate angle, the edge-stitched sheets P1 that have slipped off the guide plate 64 are aligned along the sides 69 of the tray 68 and saddle-stitched. The sheets 1) and 2t are aligned along the other side 70 of the t tray 68.

Saddle-stitch binding of MP by the bookbinding device 46 comprising the sheet folding section 45 and sheet binding section 57 described above will now be explained.

The leading edge of the paper P sent 11 from the fixing unit 34 to the paper folding unit 45 is moved by the transport rollers 47, 48 and the sponge roller 5.
1.51, and comes into contact with a stopper 54, which is arranged in advance to match the size of the paper P, and stops. After that, the sponge rollers 51, 51 continue to rotate, but their conveying force is weak, so there is no risk that the paper P will buckle.

Then, as the paper P is subsequently transported by the transport rollers 47 and 48, the paper P starts to be swallowed near the end point ζ1 of the path 50. At this time, the incomplete circumferential roller 49 rotates 11n1 in response to a signal from the sensor 53 that has detected the paper P, and conveys the bent paper P [1-ra 47 and roller 49
It gets caught in the gap and forms a crease in the center of the paper P. [1-The missing part of the roller 49 faces the conveyance roller 47, but before this state is reached, the slots 1 to 54 retreat from the passage 52. When the sheet P11 is conveyed with a crease formed in the center by the conveying force of the sponge openings 51 and 51, the paper sheet P11 is conveyed to the paper binding section 57 from the direction of the rollers 55 and 55. supplied to

Both guide plates 63 and 64 of the stitching paper binding unit 57 to which the paper P with a crease formed in the center is supplied are arranged so that the leading end of the guide plate 64 is positioned slightly downward, as shown by the solid line in FIG. are located in the same plane and are inclined. At this time, the non-binding tray 56 is placed at the solid line position in FIG.

In this state, the sheets P supplied to both guide plates 63 and 641 are moved one by one to the width of both wall plates 6 by the action of the opening 67.
5 and 66. In this way, all the sheets P constituting one booklet are placed on both guide plates 63.
, 64, the wall plate 66 is moved in the direction of the support shaft 62, and the paper P is folded "1 is received L-j".
Pp5) 9 ■ Move the paper P to J, which is located on the edge. Then, rotate both guide plates 63 and 64 to the positions shown in chain lines in FIG. The sheets P are aligned along the edges, and the binding tool 58 is lowered to bind the sheets P along the folds of the sheets P. Finally, one guide plate 6
3 to the solid line position d, the wall plate 66 is moved back 11! The saddle-stitched sheets P slide down along the guide plate 64 and are accumulated in the tray 68.

In order to explain the operation of a manuscript for saddle stitching using the recirculating manuscript handling device w4, 10 sheets of A4 side-out double-sided manuscripts with regular page order were copied onto both sides of 5 sheets of A3 paper,
Consider the case of saddle-stitch binding.
