ABSTRACT:
An apparatus is provided with a movable cartridge casing capable of facilitating film cartridge loading and unloading operations. In a loading operation, the cartridge casing is positioned at a cartridge receiving position outside the body of the apparatus so that the film cartridge can easily be inserted in the cartridge casing, the cartridge casing containing the film cartridge is pushed into the body to an intermediate position where the film spool of the film cartridge is separated from a spool driving shaft, and then the cartridge casing is moved toward the spool driving shaft along a line substantially parallel to the axis of the spool driving shaft to bring the film spool into engagement with the spool driving shaft. In an unloading operation, the cartridge casing is moved away from the spool driving shaft to the intermediate position along the line substantially parallel to the axis of the spool driving shaft to separate the film spool from the spool driving shaft, and then the cartridge casing is moved to the cartridge receiving position outside the body.
