The invention discloses a drive roller for winding a film medium, which comprises a rotor wound by the film medium on the surface, an electric end bracket and a manual end bracket, wherein the rotor of the drive roller is internally provided with a motor which is matched with the electric end bracket and the manual end bracket so as to ensure that the winding function of a film can be realized, thereby eliminating constructive interference caused by larger mounting spaces of a conventional gear case and a belt case, eliminating inconvenient mounting and hopping errors caused by mounting and manufacturing factors when the roller is arranged on an output shaft of the conventional gear case or the belt case and improving the transmission precision. Manual and electric plug positions of the drive roller are respectively positioned at both ends of a supporting shaft of the roller; at the time of a manual operation, a bolt is pressed and a handle is rotated; and an electric operation can berealized by directly plugging an electric plug sheet of a plug on an electric shaft of the roller. The rotor is convenient for being replaced and mounted, thereby improving the working efficiency.
