摘要： A pre-winding type photographic camera is provided with a mode changing mechanism for changing its operational mode between a pre-winding mode in which film is drawn out from a film magazine loaded in the camera and is taken up around the spool of the camera prior to photographing, and photographing mode in which the film is rewound into the film magazine by one frame each time the film is exposed. The mode changing mechanism is arranged to set the operational mode to the pre-winding mode by, in response to the opening of the backlid of the camera, bringing a mode changing member to a pre-winding mode position, and at the same time causing a force to be charged for bringing the mode changing member to a photographing mode position, and by retaining the mode changing member in the pre-winding mode position in response to the opening of the backlid of the camera, and is arranged to change the operational mode to the photographing mode by releasing the mode changing member in response to completion of the pre-winding mode operation, thereby permitting the mode changing member to move to the photographing mode position under the charged force. The mode changing mechanism is further provided with a magazine switch which is closed in response either to insertion or removal of the magazine and is kept closed until it is opened in response to the opening of the backlid of the camera. The magazine switch is inserted into the energizing circuit of the driving motor for driving the film in the pre-winding mode operation in series with the driving motor.

摘要： A lens-fitted photographic film package has at least an unexposed rolled film, a taking lens, a film transportiong mechanism, an exposure mechanism and an electronic flash as a whole contained in a light-tight case. The light-tight case comprises a main case section formed with a chamber containing therein light-tightly the unexposed rolled film and a front cover section attached to the main case section, the front cover section being formed with at least one opening for partially receiving therein a member of at least one of the mechanisms mounted on the main case section projecting beyond a plane defined by surfaces of the main case section in contact with an inner surface of the front cover section when the front cover section is securely attached to the main case section. The electronic flash unit is short-circuited to maintain the condenser of the flash unit discharged until the rolled film has been loaded in the light-tight case, so as to prevent accidental flashing that would expose the film. The lens-fitted photographic film package is enclosed in an external container having a weakened openable portion capable of being broken away from the external container to expose the contained rolled film for removal after exposure.

摘要： A mode change-over device for a mode change-over device for a pre-winding type camera in which, after a loading of a film patrone in the camera and before the shooting, a pre-winding of the film is conducted to fully pre-wind the film on a spool and, when the pre-winding is finished, a mode retaining member is unlocked so as to release a mode change-over member thereby operating a mode change-over switch for a shooting mode, such as to allow an unwinding of the film in a frame-by-frame fashion for each shooting exposure, while the mode change-over member is charged by an opening of a back lid of the camera, the mode change-over device comprising; a counter adapted to operate in response to winding and rewinding of the camera; a retaining member for locking the mode retaining member when the back lid has been opened erroneously or accidentally; and a counter engaging member which prevents the retaining member from locking the mode change-over member when the counter is in the initial position, whereas, when the counter is in the counting position, operates the retaining member for making the retaining member lock the mode change-over member.

摘要： In a camera of the type having a film supply chamber opening at the bottom of the camera into which a container including a coiled strip film with its leader previously drawn out is inserted for film loading, a film supporting apparatus for holding the loaded film flat in film plane comprises a pressure plate and a holding frame for resiliently holding the pressure plate in cantilever fashion. The pressure plate can be displaced in the direction parallel to optical axis of the camera for assured advancement of the film to a film take-up chamber.
