Abstract: A three side trimmer has a trimming unit 1, an accumulating unit 3, a discharge unit 2 and a conveying mechanism 4 conveying trimmed booklets BK to the accumulating unit. The accumulating unit has a shelf 5 movable in a vertical direction, and a drive roller conveyor 7 on 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.

Abstract: The trimmer includes: a pusher 2 that pushes the bound material 1; a pusher moving device that moves the pusher; a positioning part 111 that positions the bound material pushed by the pusher; an allowable position memory that memorizes an allowable position range relevant to the pusher; an allowable reaction force memory that memorizes an allowable reaction force range relevant to the pusher; and a determiner that determines whether a length of the bound material is normal or abnormal. The determiner determines that: the length L of the bound material is normal; or the length L of the bound material is abnormal.

The unit is arranged a gluing unit 4 that applies glue to both lateral edges of a top surface of each signature received from the signature conveyance unit. The unit is arranged an accumulation unit 5 that sequentially stacks the signatures received from the gluing unit on one another while jogging the stacked signatures to form a book block B. The unit is arranged a second press unit 6 that discharges the book block received from the accumulation unit after pressing the same along the folds.

Abstract: 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.

Abstract: A book binding apparatus is provided with a conveyor belt 5 having a book block conveyance surface 13 extending obliquely downward toward a pair of clamp plates 3 and 4 of a clamper 2 at a book block supply position A. A guide plate 21 is attached to the clamp plate 4 on the conveyor belt side and can swing between a standing position and a tilted position. When the pair of clamp plates is placed in a closed position, the guide plate is held in the standing position. When the pair of clamp plates is placed in an open position at the book block supply position, the guide plate swings from the standing position to the tilted position and connects to the book block conveyance surface.

Abstract: A sheet process apparatus images a code printed on a fed sheet, and a control unit acquires image data of the imaged code, reads information of the code from the image data, measures a real position of the code from the image data, retrieves position information corresponding to the read information of the code, calculates an amount of deviation between the measured real position of the code and a reference position, corrects the position information on the basis of the amount of the calculated deviation so as to determine a target position, and outputs the target position. The apparatus and corresponding method do not need the sheet to have a wide space for printing both a cut mark and the code, and do not recognize another mark as the cut mark.

Abstract: The creaser 2 includes a project part 21 for forming the crease 120 on the sheet 101 and a receive part 22 for receiving the project part 21. The project part 21 is moved between a crease position and a standby potion, the project part 21 being at the crease position so as to form the crease 120 on the sheet 101, the project part 21 being away from the sheet 101 at the standby position so as not to form the crease 120 on the sheet 101. The input device 6 includes a selector 60 for selecting the sheet 101 to be creased by the creaser 2 from among the sheets 101 fed from the conveyer 1, the input device 6 sending the information of the selection to the controller 5.

Abstract: An edge portion of a bound material is provided with first and second lines. The first and second lines are spaced at a small interval and arranged in parallel to each other. The first line is arranged outside of the second line of the bound material. A control unit controls first and second drive mechanisms in such a manner that the edge portion of the bound material is cut at the first line by a trim cutter, then the trim cutter or the table is moved at the small interval in a moving direction toward the second line, and then the edge portion of the bound material is cut at the second line by the trim cutter.

Abstract: A scoring machine incorporated in a sheet folding apparatus forms scores on sheets according to a folding pattern. The scoring machine comprises upper and lower rotary shafts provided with pairs of convex and concave rollers, and a positioning unit slidably attached to a slide guide. When a rotatable member is arranged at a standing position, the convex roller engages with a groove on one end face of the rotatable member, or the concave roller engages with a projection on the other end face of the rotatable member. A sequence pattern of the pairs of convex and concave rollers on the upper and lower rotary shafts corresponding to the folding pattern is displayed on a display. The positioning unit stops at the specified positions of the pairs of convex and concave rollers while sliding.

Abstract: A sheet is intermittently advanced or alternately advanced and retreated by a pair of feed rollers in synchronization with rotation of a pair of magnet and anvil rollers so that the pair of magnet and anvil rollers makes two or more revolutions while the sheet passes through the pair of magnet and anvil rollers. The punching of the same pattern is performed by a flexible die at a plurality of areas of the sheet spaced in a sheet conveying direction.

Abstract: Each pair of bearing units for each of magnet and anvil rollers are movable in a vertical direction. Each of large diameter portions of the anvil roller is supported by a pair of support rollers. Each of large diameter portions of the magnet roller is pressed against the corresponding large diameter portion of the anvil roller by a pair of press rollers. Each stopper is moved between a first position in which it projects into a clearance between vertically opposed bearing units and a second position in which it retracts from the first position. When the stoppers are located at the first position, the opposed large diameter portions of the magnet and anvil rollers separate from each other, and when the stoppers are located at the second position, the opposed large diameter portions of the magnet and anvil rollers contact with each other.

Abstract: The paper feeder comprises a first transport unit (5) to transport a sheet (S) on top of a paper stack (2) on a paper loading table (3), and a second transport unit (6) to discharge sheets transferred from the first transport unit toward a binding device. The first transport unit begins transporting the next sheet each time a sheet is discharged from the second transport unit. Image data for a specified printed portion on the first sheet in the paper stack is stored in memory (19) as reference data. A camera (14) is disposed above the paper stack and photographs a region corresponding to the specified printed portion on the topmost sheet. A control unit (18) compares the image data for the paper photographed by the camera with the reference data, and if the image data matches the reference data, the first transport unit operations are paused.
