摘要： In a film cassette, a film spool is rotatable inside a cassette shell in an unwinding direction to thrust a leader section of a filmstrip coiled about the spool from within a light-tight film passageway to the exterior of the shell and in a winding direction to return the leader to the interior of the shell. A unidirectional arresting device is movable into engagement with the spool to prevent rotation of the spool in only the winding direction. The filmstrip includes an inclined edge for moving the arresting device out of engagement with the spool responsive to thrusting the leader substantially to the exterior of the shell, to allow the spool to be rotated in the winding direction in order to return the leader to the interior of the shell, and for permitting the arresting device to move into engagement with the spool responsive to return of the leader to within the passageway, to prevent the spool from being rotated further in the winding direction to thereby retain the leader in the passageway.

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： A camera has a body having an exposure frame surrounding an exposure opening. The exposure frame has a window. A mask core is mounted in the body. The mask core has an axis of rotation extending transverse to the exposure frame. The mask core has a plurality of sectors arranged about the axis of rotation. Each sector has an active position adjoining the window. Each sector shades the window differently in the respective active position. A drive is coupled to the mask core. The drive selectively rotates the mask core between the active positions of each of the sectors.

摘要： A camera comprising a slide manually movable in forward and reverse directions, and a spool drive device connectable with a film spool for rotation in a winding direction to similarly rotate the film spool, is characterized in that the slide and the spool drive device are engaged with each other at a first location, to rotate the spool drive device in the winding direction, and simultaneously slip in contact with each other at an opposite location, to not interfere with rotation of the spool drive device in the winding direction, when the slide is moved in the forward direction, and are engaged with each other at the opposite location, to rotate the spool drive device in the winding direction, and simultaneously slip in contact with each other at the first location, to not interfere with rotation of the spool drive device in the winding direction, when the slide is moved in the reverse direction, whereby a two-way drive coupling is created between the slide and the spool drive device.

摘要： Data bits representing different aspect ratio formats of film image frames are optically recorded on photographic film by means of light emitting devices energized from the flash charge storage capacitor. The light emitting devices are driven by a constant current source control circuit, the control circuit and light emitting devices being coupled to the capacitor by the flash sync switch. Data bit format selection is achieved by either user operated light emitting device selection switches or by means of an optical bit forming mask having plural aperture selectable by means of a movable slide shutter.

摘要： An apparatus for assembling a prewind type camera having a film roll cheer with an open portion for containing an unexposed roll of film. According to the invention, a vacuum is applied to the interior of the film roll cheer at the time the prewound film roll is loaded into the film roll cheer through the open portion to maintain the film roll in a wound state after the roll is released. The vacuum remains applied until a lighttight cover is fixedly attached to the open portion of the film roll chamber thereby restraining the film roll.

摘要： A camera of the prewind or normal wind type that writes data on a roll of film to indicate where specific frames on the roll of film have been exposed and unexposed and detects the presence of that data on the film to determine where additional exposures may be made on the roll of film. The camera writes data on the magnetically sensitive layer of the roll of film in bursts, wherein each burst is separated from each other burst with nonwritten portions of film. BY using one pattern of data and spaces for the marking of exposed frames and another pattern for unexposed frames, prewind and normal wind cameras can interchange partially exposed rolls of film without explicitly decoding magnetic data.

摘要： A photographic camera comprises a camera body with a loading chamber for receiving a film cassette endwise, a door supported for pivotal closing and opening movement to cover and uncover the chamber, a latch for preventing pivotal opening movement of the door but which can be disabled to permit the door to be opened, and an ejecting device for pushing the cassette endwise at least part way out of the chamber. According to the invention, the ejecting device includes a single piece means supported for movement in an ejecting direction for first disabling the latch to permit the door to be opened and then pushing the cassette endwise at least part way out of the chamber when the door is opened.

摘要： An electrical drive motor system for a camera having a read head for reading magnetically encoded data from a filmstrip during a reel-to-reel transport of the film, includes a mechanism for storing energy in a mechanical motor spring. The energy stored in the spring is used to temporarily continue or complete the advance of the film with the electric motor shut off, to allow the read head to operate without electromagnetic interference from the electric motor.
