Claims

[Scope of utility model registration request]

In a double-sided copying machine having a reversal conveyance device that switches back the transfer paper after copying the first side and sends it to the transfer unit for copying the second side, an entrance conveyance path toward the reversal conveyance device; Exit conveyance paths from the reversing conveyance device to the transfer section are set to face each other in space, and a light emitting body as a sheet detection means for detecting the arrival of transfer paper is provided on the entrance conveyance path, and a light emitting body is provided as a sheet detection means for detecting the arrival of the transfer paper on the exit conveyance path. A paper detection device for a reversing conveyance device for double-sided copying, characterized in that a common light-emitting body that also serves as a light-emitting body as a sheet detection means for detecting feeding is disposed between both of the conveyance paths.
