This invention provides a reversing device for ring-bound books that can easily and reliably reverse the stacking direction of multiple sheets of paper on the backing board of a ring-bound book. [Solution] The system comprises a loading section, an articulated robot, an unloading section, and an engaging member. The articulated robot, by moving a chuck 34 that grips the ring-bound booklet 1, engages the paper 4 on the chuck 34 side with the engaging member 50 while the multiple sheets of paper 4 are hanging down from the ring-shaped binder 6 by their own weight. Then, by moving the chuck 34 in a direction away from the engaging member 50 and downward, the multiple sheets of paper 4 are rotated, reversing the stacking direction of the paper 4 on the base sheet 2, and the ring-bound booklet 1 is placed on the unloading section with the paper 4 stacked on the other side 2b of the base sheet 2.

To provide a technology capable of improving a spread property of a pocket book more than a conventional article.SOLUTION: A pocket book has a body part, a lower hardening part, a back hardening part and a cover part. The body part is formed as a structure of binding a plurality of unit structures by a yarn sewer by laminating the plurality of unit structures with a sheet or a sheet folding-back body constituted by folding back the sheet as a unit structure. The lower hardening part is constituted by a hardened object of an aqueous emulsion adhesive of including polyvinyl acetate as a main component, and is coated on a place bound by the yarn sewer in the body part, and hardens the lower part of the body part. The back hardening part is constituted by a hardened object of a synthetic rubber type hot melt adhesive of including a styrene type thermoplastic elastomer as a main component, and is coated on a lower hardened place, and hardens the back of the body part.SELECTED DRAWING: Figure 2

This image forming system comprises: an image forming unit that forms an image on a sheet; a perforation processing unit that performs perforation on the sheet on which the image has been formed by the image forming unit; a bookbinding processing unit that performs bookbinding processing including binding and folding on a plurality of sheets including the sheet on which the perforation processing has been performed by the perforation processing unit; a corner back processing unit that performs corner back processing for forming a corner back part on a back of a booklet bound by the bookbinding processing unit; and an adjustment unit that adjusts a position of the perforation by the perforation processing unit on the basis of an execution instruction of the corner back processing by the corner back processing unit.

To precisely align and bind a bundle of paper with a simple configuration, a printer (100) includes a paper discharge tray (12a) that is configured to accumulate paper (201) discharged from a discharge portion (13b); and a holding member (110) that is provided at a position where the paper (201) discharged from the discharge portion (13b) is stacked. The holding member (110) is configured to be integrated with the paper discharge tray (12a) and includes a pair of side edge guide portions (112,113) that are configured to guide opposite side edges (201b, 201c) of the paper (201). The holding member (110) is configured to be held to be movable to a position of the paper (201) in a width direction (W) where the paper (201) is stored between the pair of side edge guide portions (112, 113) in response to a force acting when the discharged paper (201) comes into contact with the pair of side edge guide portions (112, 113).

This image forming system comprises: an image forming unit that forms an image on a sheet; a perforation processing unit that performs perforation processing on the sheet on which the image was formed by the image forming unit; a bookbinding processing unit that performs bookbinding processing, including binding and folding, on a plurality of sheets including the sheet subjected to perforation processing by the perforation processing unit; a square-back processing unit that performs square-back processing for forming a square-back portion on the back of a booklet bound by the bookbinding processing unit; and a display unit that, during the execution of the perforation processing and the square-back processing, presents a display prompting the insertion of a length up to a position where the perforation processing is performed from the edge of the square-back portion.

To provide a constitution for improving positional accuracy of a regulating part for regulating a projection quantity of the back of a sheet bundle from a clamp.SOLUTION: When the regulating portion moves from the initial position to the regulating position, the regulating portion abuts against the spine of the sheet bundle to regulate the amount of protrusion of the sheet bundle from the clamping position of the clamp. The adjustment unit adjusts in advance the initial position of the regulation unit with respect to the clamp position each time the square back processing is performed.SELECTED DRAWING: Figure 15

The present invention aims to provide a device that allows for easy setting of perforation at desired locations when performing corner processing and perforation processing on a folded sheet bundle. [Solution] When performing corner back processing and perforation processing on a folded sheet bundle, the presence or absence of corner back processing is input, the starting position of the perforation processing is predetermined, and then the distance to the perforation processing position is input, thereby enabling perforation at the intended location without causing positional shift due to corner back processing.

A back processing section C2 performs back processing to press a ridge portion of a sheet bundle sandwiched between an upper jig unit 121 and a lower jig unit 120 by a pressing roller 123 so that the ridge portion of the sheet bundle protrudes downstream with respect to the upper jig unit 121 and the lower jig unit 120. The saddle controller is capable of executing a mode in which, in a state in which nip by the upper jig unit 121 and the lower jig unit 120 on the bundle of sheets undergoing the back treatment by the back treatment section C2 is released, the bundle of sheets undergoing the back treatment is conveyed downstream in a conveyance direction by a saddle third roller pair 118, and in which the bundle of sheets undergoing the back treatment by the back treatment section C2 is conveyed downstream in the conveyance direction by the saddle third roller pair 118. And performing the back processing again on the sheet bundle by the back processing portion C2.

The utility model provides rounding and ridging equipment, which is used for rounding book blocks and comprises a fixed plate, a movable plate, a driving part and a forming part. The movable plate and the fixed plate are arranged in parallel, and the movable plate can move relative to the fixed plate in the direction perpendicular to the fixed plate. The driving part drives the movable plate to be close to or far away from the fixed plate so as to clamp the book block between the fixed plate and the movable plate or release the book block. And the spine position of the book block extends out of the range of the fixed plate and the movable plate. And the forming part is controlled to apply pressure to the edge of the spine, so that the spine is formed into an outwards convex arc shape. The embodiment of the utility model is not limited by the specification of the book block, and can be suitable for book blocks with different sizes or thicknesses. After the book block is fixed by the fixed plate and the movable plate, the pressure applied by the forming part acts on the edge of the spine, the influence of the thickness of the book block is small, and the application range of the rounding and ridging equipment can be further widened.
