PROBLEM TO BE SOLVED: To maintain original cutting accuracy even when the edge side of a cover fixed to the rear surface of a booklet greatly jumps out of the edge of the booklet.SOLUTION: The pushing and moving device of edges of a booklet with a cover in a three-side trimmer is configured to position a booklet H with a cover which is carried in to be cut, and to push and move the edge of the positioned booklet H by a pusher 4 to position the edge of the booklet to a cutting position. A cover turning guide 11 is disposed continuously to the pusher 4, a part jumping out of the edge of the booklet H with the cover HO of the booklet H with the cover to be carried in is turned up above the pusher 4 by a cover turning guide 11 to bring the edge of the booklet H into contact with the pusher 4. Thus, lowering of positioning accuracy caused by bending of the cover H during edge cutting is suppressed. |
