It is an object to provide a trimmer that can trim a fore-edge portion of a bound material except a cover and that can be excellent in productivity and cost. A cover has flap portions adjacent to the fore-edge portion of the bound material, a trimmer includes: a trim cutter that trims the bound material; a blade receiving portion that receives an edge of the trim cutter; a base portion and a pressure portion that nip and position the bound material; and a pair of guide portions arranged for movement in a direction close to or away from the bound material, wherein the guide portions are inserted between the book block and the cover so as to peel the cover together with the flap portions up when the fore-edge portion of the bound material is trimmed by the trim cutter.

Processing unitstoaligned along the transport path for a sheet bundle S are accommodated in a housing together with transport unitsand. Windowstoare provided in the housing front face, and variable-color lighting unitsare arranged inside the housing. Light emitting surfaces (projection plates) of the variable-color lighting units are arranged facing the windows. Sensor units, andthat detect an anomaly of an operation of the transport unit and sensor unitsandthat detect an anomaly of the operation of respective processing units are provided. A binding processing unit stops when an anomaly is detected by the sensor unit, when a system error occurs, or when an emergency stop instruction is input. The color of emission light from a light emitting surface changes to indicate the operation status of the binding processing system.

A three side trimmer has a trimming unit, an accumulating unit, a discharge unitand a conveying mechanismconveying trimmed booklets BK to the accumulating unit. The accumulating unit has a shelfmovable in a vertical direction, and a drive roller conveyoron the shelf. The accumulating unit, in a mode, delivers the trimmed booklets to the discharge unit at every accumulation of a predetermined number of the trimmed booklets and, in another mode, accumulates the trimmed booklets without delivering.

When a length in a conveying direction of a margin to be cut off is shorter than a predetermined distance between a cutting part and a second conveying part, a sheet cutting machine feeds a first sheet to the cutting part using a first conveying part while keeping the second conveying part positioned at a conveying path. When the length is equal to or longer than the predetermined distance, the machine feeds the first sheet to the cutting part using the first conveying part after upwardly retracting the second conveying part from the conveying path using a retracting mechanism.

A table () is located in a first position and a second position which is rotated at 90 degrees from the first position. A cover () is arranged on a top face of the table () and fixed to the table () by fixing means (). Cardboards are preliminarily attached to predetermined positions on a rear face of the cover (), and an outer margin of a predetermined width is formed outside the cardboard. Folding units () are arranged on either side of the table (), and guided by guide rails () for reciprocal linear movement in directions toward and away from the table (). The folding units () are located in an outer margin folding position at which said folding units () engage with the cover () on the table () and fold the outer margin of the cover () so as to attach the outer margin to the cardboards, and a standby position at which the folding units () separate from the cover (). A control unit controls the table () and the folding units (). The folding units () are synchronized with each other in such a manner that the folding units () simultaneously fold the outer margin of the cover () each time the table () is located in the first and second positions.
