The present technology relates generally to devices and methods for preserving the integrity of folders that are placed into ringed binders or notebooks, preferably folders that are made of paper or other like material, and which are used for example for the transport and storage of papers by students or other types of users.

A binding tool for paper sheets includes a base member extending in a longitudinal direction; and a plurality of first binding members and second binding members each having a base end portion formed protruding outward in a width direction from the base member and a tip end portion integral with the base end portion and curved inward in the width direction so as to be movable between a binding position where the tip end portions contact each other and an open position where the tip end portions are separated from each other by a prescribed distance. The base end portions are positionally displaced from each other by at least an amount corresponding to a thickness TH of the base end portion in the longitudinal direction when the tip end portions positioned facing each other in the width direction are in contact with each other in the binding position.

A book has a front cover having a first edge which is unconnected, and an opposing second edge which is connected to a spine. A back cover has a first edge which is connected to the spine and an opposing second edge which is connected to flexible joint or fold-line. The book has a third cover having a first edge which is connected to the flexible joint, that couples the third cover to the back cover, and an opposing second edge which is connected to binding. The front cover is configured to fold back about the spine to retain the third cover proximal the second edge of the third cover to retain the book in a propped-up position for reading. A page holder slides along the left and right sides of the third cover and has an opening that allows a page to be pushed therethrough.

A recording medium post-processing device includes a binding unit and a hole forming unit. The binding unit performs a binding process on a recording medium bundle. The hole forming unit performs a hole forming process in a region of recording media that constitute the recording medium bundle including a part of a binding region in which the binding process is performed.

A binding tool for paper sheets includes a base member extending in a longitudinal direction; and a plurality of first binding members and second binding members each having a base end portion formed protruding outward in a width direction from the base member and a tip end portion integral with the base end portion and curved inward in the width direction so as to be movable between a binding position where the tip end portions contact each other and an open position where the tip end portions are separated from each other by a prescribed distance. The base end portions are positionally displaced from each other by at least an amount corresponding to a thickness TH of the base end portion in the longitudinal direction when the tip end portions positioned facing each other in the width direction are in contact with each other in the binding position.

A file folder having front and back covers delineated from each other by a spine therebetween is formed with a pocket located at the outboard edge of at least one of the front and back covers. The pocket has closures at the top and bottom edges and also at the outboard edge of the cover upon which it is formed. The pocket has a mouth that opens toward the spine. At least one lock wing is formed by a patch of stiff material having a fixed portion secured to the cover having the pocket at the spine. The lock wing also has a free portion that extends toward the mouth of the pocket and forms an acute angle with the cover to which the lock wing is secured. Papers, media, or other contents can be inserted into the open mouth of the pocket and the lock wing can be resiliently flexed to receive the inboard extremity of the pocket contents beneath it. The contents of the pocket are thereby securely held in the pocket by the constraints of the pocket closures and the lock wing.

A binding tool for paper sheets includes: a base member extending in a longitudinal direction; and a plurality of first binding members and second binding members each having a base end portion formed protruding outward in a width direction from the base member and a tip end portion integral with the base end portion and curved inward in the width direction so as to be movable between a binding position where the tip end portions contact each other and an open position where the tip end portions are separated from each other by a prescribed distance. The base end portions are positionally displaced from each other by at least an amount corresponding to a thickness TH of the base end portion in the longitudinal direction when the tip end portions positioned facing each other in the width direction are in contact with each other in the binding position.

The invention relates to a sticker, and/or to an insert for a book.

The sticker of the present invention is suitable for inserting into a loop-bound book, and comprises:

(i) a detachable coupling means (preferably elongate such as a finger portion), which can be (i.e. which is capable of being) detachably coupled to the binding of a loop-bound book; and
(ii) a sticky body for attachment to a material, in particular for attachment to a sheet material and/or to a generally planar material, such as a piece (e.g. sheet) of paper or a plastic sheet;
and wherein the sticker is capable of functioning as an attachment for attaching the material to the loop binding of the book.

A book has a front cover having a first edge which is unconnected, and an opposing second edge which is connected to a spine. A back cover has first edge which is connected to the spine and an opposing second edge which is connected to flexible joint or fold-line. The book has a third cover having a first edge which is connected to the flexible joint, that couples the third cover to the back cover, and an opposing second edge which is connected to binding. The front cover is configured to fold back about the spine to retain the third cover proximal the second edge of the third cover to retain the book in a propped-up position for reading. A page holder slides along the left and right sides of the third cover and has an opening that allows a page to be pushed therethrough.
