ABSTRACT:
A recorder motor with an encoder, for forming an image on a record medium in accordance with image information, has the encoder on the outside of the motor case and a plastic dust-proof cover for the encoder mounted on the case. Thus, contamination by dust or ink mist is prevented, and stable and high precision motor rotation is maintained.
