Claims

[Scope of utility model registration request]

In an electrophotographic copying machine where the transfer paper is separated from the photoreceptor by a separation claw after transfer, the leading edge of the transfer paper is folded before transfer in order to improve the transfer paper separation. One end is swingably supported by a guide member provided near the roller pair, and is slidably supported approximately in the direction of the tangential plane of both rollers at the contact portion of the pair of rollers, and the tip of one surface of the other end is supported by a guide member provided near the roller pair. A paper folding member that abuts at a position opposite to the other axis of the roller shaft on which the surface of the transfer paper on which the image is transferred is in contact, and has a ridge corner portion for folding the transfer paper formed on the same edge on the opposite side. an elastic roller provided on the other shaft in close proximity to the paper folding ridge of the paper folding member; and means for always urging the tip of the paper folding member in a direction in which it comes into pressure contact with the former roller shaft. , a means for always biasing the member in the direction of pulling it back to the above position, and a means for always urging the member back to the above position, even after the edge portion for paper folding 1f of the paper folding member bites into the elastic roller due to the rotation of the former roller shaft. In order to push the paper folding member back to the original position, the protrusion with an arcuate cross section provided on the former roller shaft detects that the leading edge of the transfer paper has reached the pair of rollers, and rotates the former roller shaft once. 1. A device for folding a leading edge of a transfer paper, comprising means for folding the leading edge of a transfer paper and then stopping the transfer paper.
