。[Claim for Utility Model Registration] The presence or absence of transfer paper being fed while being guided by an elastic guide piece in contact with the registration rollers is detected by a reflective photo sensor installed on the upstream side of the registration rollers in the paper feeding direction. In the registration detection device for a copying machine, at least a portion of the guide piece corresponding to the reflective photo sensor is bent with respect to other portions, and light from the reflective photo sensor is reflected in a direction that does not enter the photo sensor. A resist detection device for a copying machine, characterized in that it is installed at an angle.
