摘要： A camera includes a depressible shutter release, and a film drive gear in which the shutter release and the film moving element have respective coaxial mechanisms for coaxially engaging one another only when the shutter release is depressed. In a preferred embodiment, the shutter release is part of a pivotable trigger which supports a drive spline which engages a film driving gear only when the shutter release is depressed.

摘要： A camera includes a frame having a movably attached film engaging member including a metering pawl for engaging a contained filmstrip. A light locking cover attached to the frame prevents ambient light from entering a defined light tight enclosure surrounding the film engaging member with the exception of an opening to allow a locking portion of a second movable lever within the lighttight enclosure for engaging the film engaging member. The lever includes an integral light locking portion adjacent the locking portion which blocks the opening of the first light locking cover but allows the locking portion to engage the film engaging member. The access opening of the light locking cover is sufficiently large to allow pivoting movement of the locking portion, the cover preferably including a recess to allow the light blocking portion of the lever to effectively cover the opening in a lighttight manner.

摘要： A metering apparatus for a filmstrip forms with at least one perforation for each film frame including a metering member which is configured for engaging at least one perforation for each film frame, so as to prevent the filmstrip from moving in a film advancing direction. According to the invention, the metering member includes at least one cam follower for contacting a trailing edge of a perforation to cam the metering member out of engagement with the filmstrip when the filmstrip is moved in an opposite film rewinding direction. The metering apparatus also includes a mechanism for retracting the metering member to allow the filmstrip to be subsequently advanced for film frame exposure. The retracting mechanism is mechanically coupled to the release of a high energy lever used for tripping the shutter blade of a camera so that advancement and exposure of the filmstrip can be controlled in a simple manner.

摘要： A film feeding apparatus of a camera using a film having two perforations in each frame. A perforation detecting lever has claws spaced at a predetermined distance apart from each other so that the distance therebetween is equal to the distance between the two perforations which are adjacent to each other across the boundary between frames. The perforation detecting lever engages the perforations and disengages therefrom in unison with an operation for feeding one frame to be performed after the proceeding frame is exposed to light. As a result, film feeding is allowed to proceed until both claws simultaneously engage two respective perforations in the film which occurs after the film has advanced one frame.

摘要： A camera, typically a security camera utilizing film in a cartridge, with means for determining when the film in the cartridge has been exhausted. A radiation emitter with the wavelength of the emitted radiation outside the sensitivity range of the film, a detector for the radiation of the emitter, and a reflecting surface, with the reflecting surface on one side of the film and the emitter and detector on the other side of the film so that presence of film blocks the radiation path from the emitter to the reflecting surface to the detector. A control circuit for controlling camera operation, with the radiation detector output serving to shut off power to the motor when the film supply is exhausted.

摘要： A film transporting device for use in a camera disclosed is so designed as to rewind the film such that no film portion is engaged in film take-up sprocket, resulting in an easy take out of the use film. The device in one form includes a counter that counts up the number of frames during a wind-up operation is carried out after the positioning of a film leader in contact with the take-up sprocket, and during a rewind operation, the counter counts down the same number of frames, or more, to locate the film leader in a disengaged position from the sprocket. The device in another form includes a film perforation detector. In this form, the film rewind operation is carried out until the perforation detector stops detecting the perforation. In a further form, the device includes a mechanical counter which counts up the frames used during wind-up operation, and during rewind operation counts down more than the number counted up to ensure that the film leader portion is withdrawn from the take-up sprocket.

摘要： A camera for perforated roll film includes a transport mechanism for advancing film along an exposure plane, a metering lever spring biased from an inactive toward an active position to disable the transport mechanism, and a sensing member for detecting the arrival of a perforation in the film at a predetermined position. The metering lever engages the film sensing member and biases the film sensing member into contact with the film. Sensing of a perforation and subsequent movement of the sensing member to a metering position disengages the sensing member from the metering lever and permits movement of the metering lever to its active position. Exposure operation of the shutter actuating mechanism returns the metering lever to its inactive position. A spring acting substantially parallel to the exposure plane is operative to return the sensing member to its sensing position upon subsequent operation of the film transport mechanism.

摘要： A camera having a structure for controlling the tripping of the shutter and the movement of the film. A film-engaging structure has a position for holding the film against movement as well as a retracted position displaced from the film. A shutter-tripping structure when moving from a cocked to a rest position engages the film-engaging structure to retract the latter away from the film, the shutter-tripping structure also tripping the camera shutter when released by manual operation from its cocked position for movement to its rest position. The shutter-tripping structure is displaced from its rest to its cocked position in connection with the transportation of the film, and this movement of the shutter-tripping structure releases the film-engaging structure for movement to its film holding position.

摘要： A frame counter changeover and film-metering device is interconnected with a film guide changeover device to enable a camera to operate with different lengths and thickness of film. The film guide changeover device consists of two slidable pressure plates. Upon operation of an external control, the gap between the two plates is varied to accommodate different film thicknesses. The external control also adjusts the frame counter to accommodate different lengths of film.
