A paper binding device is configured to hold a plurality of paper sheets together utilizing aligned holes formed in each of the plurality of sheets. A plurality of bendable extensions extend from at least one flat first surface of a first elongated part. Each of the plurality of bendable extensions includes two cylindrically-shaped posts disposed adjacent to one another and separated by a gap. A plurality of bridges connect the two cylindrically-shaped posts along the gap. A second part includes a plurality of through apertures which are disposed from at least one flat second surface through to an opposite surface. A plurality of elongated channels are openly formed in the opposite surface. The plurality of bendable extensions are fitted through the plurality of through apertures and are configured to be manipulated by a user to bend and lock into the plurality of elongated channels.

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, with a metallic staple, 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 second binding section saddle-stitching, without using the metallic staple, the paper sheet bundle being regulated by the stopper at the binding position around the center of the paper sheet bundle in the sheet conveying direction; and a folding section folding in half the paper sheet bundle regulated by the stopper at a folding position at which the paper sheet bundle is bound by the first binding section or second binding section.

According to an aspect of the present invention, there is provided a sheet processing device including a first teeth portion, a second teeth portion that clamps and binds a sheet bundle with the first teeth portion, a first support portion supporting the first teeth portion, a shaft, and a second support portion supporting the second teeth portion. The second support portion includes first and second arm members integrally supported to be capable of swinging around the shaft between a binding position in which the second teeth portion clamps and binds the sheet bundle with the first teeth portion and a standby position in which the second teeth portion is apart from the first teeth portion. The second arm member is provided over the first arm member so as to cover a part of the first arm member.

A staple-less binding unit including a pair of upper and lower teeth binds a sheet bundle which is discharged to an intermediate processing tray by a sheet discharge portion and whose one edge abuts against a rear edge stopper. A control portion switches a binding mode of the staple-less binding unit that implements the binding process on the sheet bundle in a first binding mode of binding the sheet bundle without any staple such that the pair of upper and lower teeth bite across an edge of the sheet bundle and in a second binding mode of binding the sheet bundle without any staple such that the pair of upper and lower teeth do not bite across any edge of the sheet bundle.

A divider assembly is shown and described herein. A divider assembly for dividing a stack of sheets, the divider assembly may include a sleeve having a first edge and an opposite second edge. A label display element inserted into the sleeve having at least one label indicia generally aligned along the first edge of the sleeve. At least one divider may include a first edge and an opposite second edge and a tab extending from the first edge. The tab may be extend beyond the first edge of the sleeve such that a user may view the at least one label indicia at a position adjacent and inward relative to the tabs.

A sheet processing apparatus includes a first binding unit configured to bind a sheet bundle; a second binding unit with greater number of bindable sheets than number of bindable sheets of the first binding unit; and a number-of-sheets determining unit configured to determine whether number of to-be-bound sheets exceeds the number of bindable sheets of the first binding unit. The first binding unit moves to a binding position, and if the number-of-sheets determining unit determines that the number of to-be-bound sheets exceeds the number of bindable sheets of the first binding unit, the first binding unit moves away from the binding position. When the number-of-sheets determining unit determines that the number of to-be-bound sheets exceeds the number of bindable sheets of the first binding unit, the second binding unit moves to the binding position.

The invention relates to a cover for disc-bound, fold-over binding systems, comprising a series of parallel T-shaped slits, characterized by the fact that the cover consist of a one-piece sandwich panel containing two rigid outer layers which are permanently attached to a flexible core layer, wherein the sandwich panel is provided with an area which runs parallel to the edge of the cover wherein between 0.1% and 100% of the outer layers of the sandwich panel is removed.

A staple-less binding unit including a pair of upper and lower teeth binds a sheet bundle which is discharged to an intermediate processing tray by a sheet discharge portion and whose one edge abuts against a rear edge stopper. A control portion switches a binding mode of the staple-less binding unit that implements the binding process on the sheet bundle in a first binding mode of binding the sheet bundle without any staple such that the pair of upper and lower teeth bite across an edge of the sheet bundle and in a second binding mode of binding the sheet bundle without any staple such that the pair of upper and lower teeth do not bite across any edge of the sheet bundle.

Disclosed is a divider adhesion strip assembly that includes a sheet with a front side and a bottom side having a perimeter that is defined by a first edge, a second edge, a third edge, and a fourth edge wherein the first edge is opposite the second edge and the third edge is opposite the fourth edge. A first laminate strip portion may be adhered to the front side of the divider sheet. The first laminate strip portion is positioned along the first edge of the sheet and extends between the third edge and the fourth edge. A plurality of apertures may be aligned adjacent the second edge of the sheet. A tab member having indicia thereon and an adhesive portion may be provided wherein the adhesive portion is configured to adhere to the first laminate strip portion such that the indicia extends past the perimeter of the sheet.
