A sheet processing apparatus includes a control unit and an attaching unit. The control unit determines a position along a surface of a sheet adjacent to an edge portion thereof, where a tag including a binding section for binding the sheet is to be attached. The attaching unit has a carrier for the tag and is moved to attach the tag to the position on the surface of the sheet determined by the control unit.

An auxiliary binding jig is configured for assisting a plurality of binding members to bind a plurality of papers into a bound document, and includes an auxiliary plate body having opposite first and second planar surfaces, and a plurality of engaging holes extending through the first and second planar surfaces and each having a constriction which divides a respective engaging hole into two hole portions and which is formed by two press tabs defining therebetween a slot communicating with the hole portions. The press tabs are configured to press against an outer ring of each binding member when each binding member is inserted into a respective engaging hole through the slot so as to position each binding member on the auxiliary plate body.

A ring mechanism for retaining loose-leaf pages includes a housing and ring members for holding loose-leaf pages that are moveable relative to the housing between an open and closed position. An actuation system moves the ring members and includes hinge plates pivotally mounted on the housing and an actuator actuating pivoting movement of the hinge plates. A travel bar of the actuation system is moveable by the actuator between a locked position blocking pivoting movement of the hinge plates and an unlocked position allowing pivoting movement of the hinge plates. The actuation system is adapted to deform while moving the travel bar from the locked position toward the unlocked position to delay the pivoting motion of the hinge plates from the movement of the actuator.

A loose-leaf notebook and its binding structure are provided. The binding structure includes a base plate. The base plate is provided with binding strips and snapping holes corresponding to the binding strips. A bottom end of each of the binding strips is fixed on the base plate, and a top end of each of the binding strips is inserted into a corresponding snapping hole. Due to the elasticity of the material itself, hands will not be hurt during writing, and loose-leaf papers can be easily flipped. If a user needs to remove or change an order of the loose-leaf papers, the user can remove the binding strips from the snapping holes to easily change papers and perform rebinding. The binding structure can also be reused by replacing the loose-leaf papers of the loose-leaf notebook.

A pocket device including a first major panel and a second major panel coupled together along a major fold line. The pocket device further includes a first pocket panel coupled to the first major panel along a first pocket fold line and forming a first pocket with the first major panel, and a second pocket panel coupled to the second major panel along a second pocket fold line and forming a second pocket with the second major panel. The first and second pocket panels are coupled along a minor fold line. A reinforcing material is positioned on at least part of at least one of the major fold line, the first pocket fold line, the second pocket fold line or the minor fold line.
