摘要:
A sheet post-processing device includes a conveying section that conveys a paper sheet; a punch section that punches punch holes in the paper sheet conveyed by the conveying section; a stacker section that stores the paper sheet in which the punch holes are punched by the punch section; a binding section that binds a paper sheet bundle stored in the stacker section with a binding member; and a controller that controls the above sections. The controller selectively performs a ring binding mode and a direct binding mode. The ring binding mode is a mode in which punch holes are punched in the paper sheet by the punch section and then the binding member is made to penetrate the punch holes for binding. The direct binding mode is a mode in which the binding member is directly driven into the paper sheet bundle without punching the punch holes in the sheet.

A sheet processing device can prevent a folded sheet bundle from being opened upon accumulation to prevent a reduction in accumulation amount thereof. The sheet processing device includes a pair of pressing rollers pressing a folding loop of a folded sheet bundle in a thickness direction, a support unit mounted to a device frame and supporting a plurality of rows of the pressing roller pairs such that intervals therebetween in the row direction are reduced stepwise, and a gripper member that makes the folding loop of the folded sheet bundle pass through the support unit in a direction that the intervals of the plurality of rows of pressing roller pairs in the row direction are reduced stepwise. The folded sheet bundle passes through the support unit by the gripper member to cause the folding loop to be sequentially pressed by the plurality of rows of pressing roller pairs.

A sheet post-processing device includes a conveying section that conveys the paper sheet, a punch section that punches punch holes in the paper sheet conveyed by the conveying section, a stacker section that stores the paper sheet in which the punch holes are punched by the punch section, a stopper section that regulates a conveying direction leading end of the paper sheet stored in the stacker section; a binding section that binds the paper sheet bundle whose leading end is regulated by the stacker section, and a folding section that folds the paper sheet bundle bound by the binding section at a predetermined folding position. The punch section punches the punch holes at the front and rear of the folding position in the sheet conveying direction, and the binding section binds the paper sheet bundle with a paper-made staple by making the paper-made staple penetrate the punch holes. With this configuration, there can be provided a sheet-post processing device capable of easily generating a booklet for simple ring binding.

Provided is an image forming system having a simple buffer mechanism and capable of preventing paging disorder when image-formed sheets are fed to a processing section. The present invention is featured in that an image forming order of a plurality of sheets to be made to stand by in a buffer section of a conveying path for guiding the sheets to a processing section is made different from an image forming order of sheets that are not made to stand by. To realize this, the system includes an image forming section, an accumulating section that accumulates image-formed sheet for processing, a conveying path along which the sheet is conveyed from the image forming section to the accumulating section, a buffer section disposed in the conveying path, in which the sheet to be fed to the accumulating section is made to temporarily stay, and a control section that controls the image forming section and the accumulating section.

A sheet processing device performs saddle stitching binding a bundle of stacked paper sheets, and includes a stacker section temporarily stacking conveyed paper sheets substantially vertically; a stopper regulating the paper sheets stacked in the stacker section; a first binding section provided in the stacker and saddle-stitching a paper sheet bundle regulated by the stopper at a binding position around a center of the paper sheet bundle in a sheet conveying direction; a folding section folding in half the paper sheet bundle regulated by the stopper; and a conveying section conveying the paper sheet bundle that has been folded in half by the folding section with a back side of the folded paper sheet bundle as a leading end in the conveying direction. The conveying section includes a second binding section binding the folded paper sheet bundle at the back side thereof.

A sheet processing device conveys a paper sheet onto which an adhesive is applied, and includes a bonding member that applies adhesives onto the conveyed paper sheet at intervals in a sheet width direction; and a protruding guide that is positioned on a conveying path, downstream of the bonding member in a sheet conveying direction, and guides the paper sheet, facing an adhesive-applied surface of the paper sheet. The protruding guide is positioned between sheet width direction lines of the adhesive-applied position and includes a protruding portion protruding into the conveying path. With this configuration, it is possible to suppress the adhesive from being adhered to a device component even in a configuration in which an adhesive-applied paper sheet is moved inside the device to make a sheet jam due to the adhesion less likely to occur.

Provided is a sheet processing device capable of preventing a folded sheet bundle from being opened after pressing to improve accumulating property and aligning property of the sheet bundle. A sheet processing device B that presses a folded sheet bundle includes a pair of pressing rollers 70 that press a fold of the folded sheet bundle in a thickness direction of the fold, a pressing roller unit 56 that moves the pressing roller pair 70 along the fold of the folded sheet bundle, and a cam member 80 that regulates an interval between the pressing roller pair 70. When the pressing roller unit 56 is moved along the fold of the folded sheet bundle to press the fold in the fold thickness direction, the cam member 80 reduces stepwise the interval between the pressing roller pair 70 in accordance with a moving direction of the pressing roller unit 56.

Provided is a sheet processing device including a carry-in path along which the paper sheet is carried in and a retreat path that branches off from the carry-in path, along which at least a part of the paper sheet stored in a stacker section is retreated in a direction opposite to a sheet conveying direction. A bonding means is disposed at a merging point between the carry-in path and retreat path. An adhesive-applied position of a preceding paper sheet is retreated to the retreat path when a next paper sheet is carried in to the stacker section, then the next paper sheet is moved to a bonding position for adhesive application. The above operations are sequentially repeated to generate a paper sheet bundle. Thus, a paper sheet bundle can be generated by bonding the paper sheets using an adhesive, so that it is possible to reduce stress to be applied to the paper sheet as compared to a case where the paper sheet bundle is bound with a metallic staple or by deforming the paper sheets themselves. Further, it is possible to comparatively reduce movement of the paper sheet applied with the adhesive to prevent the adhesive from being adhered to a portion other than the paper sheet, thereby preventing the paper sheets from being bonded to each other at a position other than a predetermined position. As a result, there can be provided a sheet processing device, that is rather small and can bond the paper sheets at a predetermined position.

Provided is an adhesive application device that applies an adhesive onto each of sequentially conveyed paper sheets, the device including: a device frame; a bonding member that delivers the adhesive for bonding the paper sheets to each other; a plurality of bonding units that are arranged in a sheet width direction and each have the bonding member; a support member that supports the bonding units on the device frame so as to be movable between a bonding position at which each bonding unit presses its bonding member to apply the adhesive onto the paper sheet and a separated position separated from the bonding position; and a moving member that moves the plurality of bonding units to the bonding position with timing shifted. Thus, it is possible to move the bonding units with a smaller drive force than in a case where the bonding units are moved simultaneously. Further, it is possible to reduce, even if the twist or wrinkles occur in the paper sheet in an initial pressing operation, the twist or wrinkles by utilizing a time lag up to the next pressing operation of the bonding units, thereby allowing adhesive application to be performed more reliably.
