An apparatus using a film cartridge in a system that a leading portion of a film contained in a cartridge is thrust to be conveyed from the cartridge, wherein an indicator showing an exposure condition is reset to an original state when an initial loading, which is executed on a film cartridge loading in an apparatus, is not executed normally, and the film is rewound, thus, it indicates 'unexposed' when a new film cartridge is loaded. While, when a winding up operation is not executed normally during a photographing, a film is rewound and an indicator showing an exposure condition, is set so as to indicate that the film is exposed. Thus, it prevents from causing a double exposure.

A waterproof camera to which an interchangeable lens unit having a waterproof construction is mounted. The waterproof camera has a lens mount provided in a camera body and to which the interchangeable lens unit is removably mounted, a ring-shaped flange provided in the lens mount and which positions the interchangeable lens unit relative to the camera camera body, an engaging member provided at an outer circumference of the ring-shaped flange and which engages with the outer circumference of one end of the interchangeable lens unit, and a waterproof member which is in pressing contact with an area of engagement between the engaging member and the outer circumference of one end of the interchangeable lens unit and prevents water from penetrating in the area of engagement.

A cartridge holder engages with a cartridge holder driving gear driven by a driving force of an ejecting motor. The ejecting motor is controlled by a microcomputer so that ejecting is performed in succession to the completion of the rewinding of the film.

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.
