ABSTRACT:
A cartridge adapter, comprising: a case into which a cartridge of a photographic film is loaded, the cartridge, including: a door for shielding an entrance/exit port of the photographic film; a door shaft which is rotated in a first direction so as to open the door and release the shielding of the entrance/exit port, the door shaft being rotated in a second direction which is the direction opposite the first direction so as to close the door and shield the entrance/exit port; and a spool shaft which is rotated in a third direction so that the photographic film is wound around the spool shaft, the spool shaft being rotated in a fourth direction which is the direction opposite the third direction so that the photographic film is conveyed out of the entrance/exit port; and a shaft body which is axially supported by the case so as to be rotatable and which engages with the door shaft of the cartridge loaded into the case, wherein the case is provided with a slit port which, when the photographic film is loaded into and unloaded from the cartridge, guides the photographic film and an opening portion which exposes the end of the spool shaft of the cartridge loaded into the case. Therefore, in a state in which the cartridge is loaded into the cartridge adapter, the cartridge can be conveyed in and out via the opening portion.
