摘要： A film advancing arrangement for a film projector having an optical system and two spools between which a film is advanced, comprises two spool supports for carrying a supply spool and a takeup spool respectively. The spool supports are pivotally mounted with respect to the housing of the projector to be positioned inside of the housing or outside of the housing so that the spools of small standard diameters may be located within the contours of the housing and the spools of large standard diameters may be mounted on the same spool supports and located outside of the housing.
