ABSTRACT:
A web feed roller is driven by a compact and simple web feed roller drive device included in the web feed roller. The web feed roller comprises a support shaft, a cylindrical hollow member rotatably supported on the support shaft, a stator provided with an electrically conductive member and fixed on the support shaft, a rotor fixed on the cylindrical hollow member to face with the stator, and an electrical connecting member connected to the conductive member of the stator. The web feed roller is electrically connected to a drive control system comprising a speed control device to control driving speed of the web feed roller, and a signal generating device for outputting a speed signal representing an actual speed of the web feed roller into the speed control device.
