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.

An integrated plastic back lid for cameras is provided with a reinforcing metal plate firmly attached to the back lid for preventing the back lid from being deformed and a pressure plate for holding a film flat which is held resiliently by the reinforcing plate. For resiliently holding the pressure plate, resiliently deformable holding arms are integrally formed either on the pressure plate or on the reinforcing plate. The pressure plate and the reinforcing plate are assembled before being attached to the back lid.

Back lid of a camera

A camera back adapted to be fitted on the back of a camera or the like has a frame for a film container pivotally mounted in the housing of the camera back for movement between the first picture taking position and a second film discharge position. A pair of processing solution spreading rollers are rotatably mounted at the top of the frame with the nip region thereof being aligned with a discharge slot in the camera back housing when the frame is in the second position. An electric motor is mounted in the housing for rotating the rollers in opposite directions through suitable gearing. An endless belt having a first outwardly directed projection and a second inwardly directed projection is entrained about a pair of pulleys in the housing, one of which is driven by the motor. An L-shaped lever is pivoted in the housing with one arm connected to the frame and the other arm having a pin adapted to be engaged by the second inwardly extending projection on the belt for pivoting the lever and the frame between the first and second positions. A slide plate having a pawl for engaging the top film in a film pack is adapted to be raised by engagement with the first outwardly extending projection for lifting the film into engagement with the rollers after the frame has been moved to the discharge position.

Camera back

An instant camera in which a self-processing type film unit is passed between a pair of spreading rollers and ejected to the exterior of the camera while a container means containing a development processing solution in the film unit is torn by the nipping force of the rollers causing said processing solution to be spread over an image forming region in said film unit, characterized by the spreading rollers being formed such that the clearance therebetween is greater at the center section thereof and smaller near the roller ends which contact the edges of said image forming region.

Instant camera

In a film unit for photography of the diffusive transfer process type including a photosensitive laminate, a mask sheet defining an image border definition with an aperture provided therein, a pod for a processing liquid etc. with, the mask sheet being made of a translucent material.
