項１記載のシート折り機。[Claims for Utility Model Registration] (1) A reversible receiving roller provided in front of the exit portion of the guide member that guides the sheet, and a receiving roller located on both sides of the exit portion of the guide member and in pressure contact with the receiving roller. It has a pair of folding rollers, and by switching the direction of rotation of the receiving roller and folding roller at a predetermined timing and rotating them, a part of the sheet is pressed between the receiving roller and the folding roller to form a crease. In the sheet folding machine, the folding roller is provided on a member pivotable about a pivot shaft so as to be movable toward and away from the receiving roller, and the member is biased by a spring means to move the folding roller. A gear fixed to the receiving roller and a gear fixed to the folding roller are brought into pressure contact with the receiving roller, and a first intermediate gear provided on the pivot shaft and a second intermediate gear rotatably provided on the pivot member A sheet folding machine characterized in that the receiving rollers are connected through gears, and the rotation of the receiving rollers is transmitted to the folding rollers so that the folding rollers rotate in synchronization. (2) The sheet folding machine according to claim 1, wherein the receiving roller has a diameter sufficiently larger than that of the folding roller.
