A cutting device includes a main body unit and a support unit. The main body unit includes a cutting unit on a lower side. The cutting unit cuts off an edge portion of paper. The support unit supports the main body unit in such a way that the main body unit rotates. The main body unit exposes a blade of the cutting unit at least on a lateral side by rotating.

A guillotine cutter () of the invention is provided with a pressing block driving mechanism () positioning a pressing block () at a standby position which is spaced upwardly from a sheet bundle (), a first operating position pressing the sheet bundle by a first pressing force, and a second operating position pressing the sheet bundle by a second pressing force which is larger than the first pressing force. The pressing block is carried by a rod () through a compression spring () at the standby position, the pressing block is supported on an upper surface of the sheet bundle at the first operating position, thereby applying the first pressing force to the sheet bundle on the basis of a resultant force of a gravitational force generated by its own weight and an biasing force generated by the compression spring, and the pressing block is pushed down by an expansion portion () of the rod while the pressing block is kept being supported on the upper surface of the sheet bundle at the second operating position, thereby applying the second pressing force on the basis of a resultant force of the first pressing force and the push-down force generated by the rod.

A paper supplying apparatus has a rotatable member around a horizontal axis, a pair of clamp plates supported by this rotatable member mutually parallel and in face-to-face relationship for clamping a book block in between, and guide plates each attached to an associated one of these clamp plates, extending downward from the clamp plates to a lower edge part of the book block when the book block is held vertically. Such a paper supplying apparatus can be removably connected to a book binding machine by attaching a guide rail to an outer wall of the book binding machine and a runner to the paper supplying apparatus. The runner is slidably engageable with the guide rail, allowing the paper supplying apparatus to move along the guide rail selectably towards or away from the book binding machine.

A three side trimmer is provided with a trimming table having a base, a first cutting stick fixed on the base opposed to a front edge trimming cutter in order to receive the knife edge of the front edge trimming cutter and, a table structure including a pair of elemental plates movable on the base along a direction parallel to the length of the first cutting stick. The first elemental plate of the table structure is provided with a second cutting stick arranged perpendicular to the first cutting stick in order to receive the knife edge of a top edge trimming cutter. The second elemental plate of the table structure is provided with a third cutting stick arranged perpendicular to the first cutting stick in order to receive the knife edge of a foot edge trimming cutter. The three side trimmer makes it possible to trim the three sides of the binding objects of different sizes without exchanging the trimming tables.
