Claims

[Claims for Utility Model Registration] (1) A folding means including a first folding roll and a second folding roll, and a folding means provided at a stage before the folding means, which presses the paper against the first folding roll, and presses the paper against the first folding roll. A device comprising a nip roll that performs a feeding operation, characterized in that the nip roll is provided so as to be able to move toward and away from the first folding roll, and the roller of the folding means is provided so that it can be rotated/stopped at will. Paper folding devices such as copying machines. (2) In the paper folding machine, when the rollers are brought into pressure contact with the nip portion of both rollers to form a crease in the paper, the rotation of the roller of the folding means is stopped;
A paper folding device for a copying machine or the like as claimed in claim 1, wherein the paper folding device is rotated again after the pressure contact is completed to fold the paper.
