The convex portion of at least one tooth portion of the pair of tooth portions has, on an opposing surface thereof opposing the convex portion of the other tooth portion, an abutting surface abutting against the convex portion of the other tooth portion when the pair of tooth portions is engaged with each other and a non-abutting surface not abutting against the convex portion of the other tooth portion when the pair of tooth portions is engaged with each other.

Abstract: A bookbinding apparatus includes a sheet aligning unit which stacks and aligns plural sheets having holes formed therein, a binding mechanism which binds the sheets aligned in the sheet aligning unit by conveying a binding component in an axial direction while rotating the binding component in a circumferential direction, a binding component storing unit which stores therein plural binding components; a binding component conveyance path which conveys the binding component from the binding component storing unit to the binding mechanism. The binding component conveyance path forms a curved conveyance path for conveying the binding component with being curved with respect to the axial direction to an end portion of a side of the aligned sheets at which the binding mechanism starts inserting the binding component, at a position that is distant from the end portion by a distance smaller than a length of one binding component.

Abstract: A binding component holding sheet is configured to detachably hold a binding component obtained by spirally winding a wire rod and includes a holder configured to hold the binding component by insertion of a circumferential portion of the spirally wound binding component. The holder is configured to hold the binding component so that an area greater than a half of the binding component in a circumferential direction protrudes to one side of the binding component holding sheet and an area less than the half of the binding component in the circumferential direction protrudes to the other side of the binding component holding sheet.

Abstract: A binder is configured such that a plane portion is formed on an outer peripheral surface of at least one ring part at a portion intersecting with a back part of the binder, and such that, when a binder holding member of a binding processing machine holds the binder, the plane portion of the binder contacts with a plane table provided on the binder holding member. Because the binder contacts the plane table on the binder holding member when the binder holding member holds the binder, the binder is held in such a state that the binder cannot incline or rotate. Thus, a binding processing operation can be carried out in the binding processing machine while the binder is held in a regular orientation. Accordingly, a mounting failure due to an inclined orientation of the binder and be resolved.

Abstract: A coil binding apparatus includes a coil forming mechanism to form a helical coil in different diameters from a wire, a binding mechanism to bind a punched portion of a paper stack with the helical, and a coil introducing mechanism disposed between the coil forming mechanism and the binding mechanism to receive the helical coil drawn out of the coil forming mechanism and to introduce the helical coil to the binding mechanism. The coil introducing mechanism has a center axis shifting unit configured to shift a coil center axis position to a coil rotation axis position. The coil center axis position is a position of a center axis of the helical coil. The coil rotation axis position is a position of a rotation axis of the helical coil when the binding mechanism rotates the helical coil to insert the helical coil into the paper stack.

The clamp movement mechanism 80 contains a clamp-opening-and-closing driving section 881 that drives the upper arms 801b, the clamp-opening-and-closing driving section 881 is provided with cams 87a, 87b, and each of the cams 87a, 87b contains a part having a given curved shape, the part keeping a normal operation range in which the upper arm 801b is moved up to a predetermined position with respect to the lower arm 801a to release the bundle of paper-sheets 3? and a U-shaped part that keeps a lock position for opening the clamp, the U-shaped part being continuous with the part having the given curved shape.

Abstract: A paper-sheet handling device is provided with a paper-sheet-holding unit 32 that causes the plurality of paper-sheets 3? to butt against a reference position and stacks these paper-sheets 3? to hold them temporarily and alignment pins 85a, 85b which align pinched holes 3a in the plurality of paper-sheets 3? temporarily held by this paper-sheet-holding unit 32, as shown in FIG. 9. In this device, it is supposed that a distance from the reference position up to a predetermined position of the alignment pins 85a, 85b is S1 and a distance from front edges of the paper-sheets 3? up to a predetermined position of the punched holes 3a is S2, the alignment pins 85a, 85b are disposed with respect to the reference position in such a manner as to satisfy a relationship of S1>S2.

Abstract: A planar section is formed on one or a plurality of ring sections of a binder, on an outer circumference side of a portion orthogonally intersecting with a spine section. When a binder holding member of a binding machine holds the binder, the planar section of the binder is permitted to abut to a planar table formed on the binder holding member. Since the planar section of the binder abuts to the planar table of the binder holding member when the binder holding member holds the spine section, the binder is held in a status where the binder cannot incline nor rotate and binding is performed by the binding machine with a prescribed posture. Thus, a possibility of causing a mounting failure due to inclination of the binder posture is eliminated.
