A film rewinder for rewinding film from a film cartridge to an intermediate cartridge. Its driving unit for rotating the film cartridge spool is also used to drive a tool for separating the film trailing end from the film cartridge spool. The film cartridge has a tool guide, so that the entire device is sufficiently compact. The film rewinder has a film cartridge receptacle and a winding unit for winding the film fed from the film cartridge into the intermediate cartridge. A film guide is provided between the receptacle and the winding unit. The spools of the two cartridges are driven by separate motors independently of each other. The tool is an arcuate member adapted to be pivoted in a circular path by the motor for the film cartridge. In order to minimize the length of the film guide and thus to minimize the size of the entire film rewinder, the film guide is provided with a release guide.
