Channels formed with a mutant prion protein PrP (82 - 146) homologous to a 7 - kDa fragment in disea

The present invention relates to a winding up device for a camera, in which a motor driven winding up shaft, a manual winding up member rotating the winding up shaft by means of manual operation and a one-way clutch means between the winding up shaft and the manual winding up member are provided, so designed that a manual winding up angle conversion means for making the ratio of the rotation angle of the manual winding up member to that of the winding up shaft at a certain determined value is provided between the manual winding up member and the one-way clutch means in such a manner that the rotation angle of the manual winding up is optionally variable by means of the manual winding up angle conversion means while the winding up angle at the time of motor drive is invariable.
