摘要： A photographic camera to be used with a film cassette having a locking member movable between respective locking and non-locking positions for arresting and releasing a film exposure status indicator in any one of several exposure status positions, is characterized in that a loading chamber is configured to receive the film cassette with the indicator in at least one of its exposure status positions and actuation means is located in the loading chamber for moving the locking member from its locking position to its non-locking position responsive to insertion of the cassette into the loading chamber and for moving the locking member from the non-locking position to the locking position responsive to removal of the cassette from the loading chamber.

摘要： Magnetic recording apparatus for a photographic still camera comprises a fixed magnetic head mounted on a film platen. The head is adapted to contact a magnetic coating on the film adjacent the image area of the film. A pressure pad is mounted in the camera on the opposite side of the film and positioned in close proximity to the film. The pressure pad is biased by a spring to apply pressure on the head through pressure on the film to assure that the film is in intimate contact with the head when the film is advancing. During film exposure when the film is stationary, the pressure pad is retracted to avoid distortion of the image plane.

摘要： A film cassette comprises a spool supported within a lighttight shell for rotation to thrust a filmstrip coiled about the spool to the exterior of the shell whether the filmstrip is unexposed or is only partly exposed, and a film exposure status indicator secured to the spool for rotation from an unexposed position to respective partly exposed and fully exposed position for providing visible indications that the filmstrip is only partly exposed or is substantially exposed. The spool has three spaced detents arranged at separate radial locations for respective engagement to lock the indicator in its unexposed, partly exposed and fully exposed positions. The shell has a radial slot in which a locking member is movable between a locking position for individually engaging any one of the detents and a non-locking position for disengaging any one of the detents. Securement means is arranged at the slot for fixing the shell and the locking member releasably to each other only when the locking member is in its locking and non-locking positions.

摘要： A film cassette is disclosed wherein a filmstrip is advanced to the outside of a light-tight cassette shell in order to expose successive imaging areas of the filmstrip and can be returned to the inside of the cassette shell before all of the imaging areas have been exposed or after the filmstrip has been substantially completely exposed. According to the invention, a film-exposure status indicator is supported on the cassette shell for movement relative to the shell from a normal first position to successive second and third positions for providing respective visible indications that the filmstrip is generally unexposed, the filmstrip has been returned to the inside of the shell before all of its imaging areas have been exposed, and the filmstrip is substantially completely exposed.

摘要： The present invention provides for a processor or processing arrangement which includes a replenishment system that meters or dispenses an amount of replenishment solution in direct relation to an amount of photosensitive media that passes through the processor or processing arrangement. The replenishment system includes a dispensing chamber and a cam roller that is operationally associated with a conveying roller. The cam roller engages a valve on the dispensing chamber. When the valve is moved to an open position in relation to a rotation of the cam roller, an amount of processing solution is metered out of the chamber in an amount related to the amount of rotation of the conveying roller.

摘要： A film projector for use with frames of processed photographic film having frame-associated image orientation data. The film projector has a light source that emits a collimated beam and a film holder that is disposed to hold individual frames of film in the beam. The film holder is pivotable between a first and second orthogonal orientations. An optical projection system receives the beam from the film holder. The optical system propagates and focuses at least a portion of the beam on a viewing plane external to the projector. A sensor is disposed to read the frame-associated image orientation data. The sensor produces a signal responsive to the image configuration information. A controller receives the signal from the sensor. A repositioner is connected to the film holder. The repositioner is operatively connected to the controller to move the film holder between the orientations responsive to the controller.

摘要： Heat generated by the projection lamp in a projecting apparatus is used to individually pop slides having improper curvature due to heat deformation. According to the invention, a slide positioned in the projection gate of the projector exhibits incorrect curvature, preferably as detected by the autofocus system of the projector, a door is opened allowing dry heat from the projection lamp to be applied directly to the slide, preferably until the slide reverts to a proper or normal curvature.

摘要： A film cassette comprises a spool supported inside a shell for rotation to thrust a filmstrip coiled about the spool to the exterior of the shell whether the filmstrip is unexposed or is partly exposed, and a film exposure status indicator secured to the spool for rotation from an unexposed position for providing a visible indication that the filmstrip is unexposed to respective partly exposed and fully exposed positions for providing visible indications that the filmstrip is only partly exposed or is substantially exposed. A spool lock is supported for movement to arrest the spool with the film exposure status indicator in the unexposed, partly exposed or fully exposed position, and to release the spool. According to the invention, the spool lock includes a film speed indicator for providing a detectable indication of the speed of the filmstrip which is not detectable when the spool lock is arresting the spool and is detectable when the spool lock has released the spool.

摘要： In a film cassette, a cassette shell has a pair of throat portions which together define a film passageway to the exterior of the shell, a spool is supported for rotation in an unwinding direction inside the shell, a convoluted film roll whose outermost convolution is a film leader is coiled about the spool, and a stripper is located immediately inwardly of the passageway to be received between a leading end of the film leader and a next-inward convolution of the film roll responsive to rotation of the spool in the unwinding direction to divert the leading end into the passageway to permit the leading end to be advanced from the shell. According to the invention, an inclined surface along one of the throat portions and an inclined surface along the other throat portion are arranged in offset co-planar relation, and a resiliently flexible shutter blade has two opposite ends one of which is secured to the inclined surface along one of the throat portions and the other of which rests freely against the inclined surface along the other throat portion to permit the leading end of the film leader to deflect the shutter blade out of its way when the leading end is advanced from the shell.
