摘要： A 3-D motion picture projector comprises two rolling loop film transport mechanisms (32,34) arranged in vertically superposed relationship with the principal components of the two mechanisms in vertical alignment with one another. Each film transport mechanism includes a cam unit (60,62) for decelerating the film as it approaches the aperture for projection. The two cam units are driven from a common vertical drive shaft (96) by toothed belt drives. The lower cam unit is mounted on an arm so that it can be swung out to an inoperative position for maintenance and service. The belt drives maintain the drive coupling at this time and automatically restore proper cam timing when the cam unit is returned to its operative position.

摘要： A web transport mechanism suitable for transporting film in cameras or projectors includes inner and outer tracks defining between them an endless path. The inner track is driven so as to cause a flexible member which is located between the tracks and in engagement therewith to roll around the outer track. The engagement between the flexible member of the track is maintained by the resilience of the flexible member in one embodiment and by magnetic forces in another embodiment. A web support surface is provided adjacent the track and arranged so that the flexible member rolls over this surface as it moves around its path. Film supply and take-up means are disposed at positions upstream and downstream (with respect to the direction of movement of the member) of the surface. Each time the member moves around its path, it successively moves a portion of the web into contact with the surface, holds it against the surface and releases it to permit a fresh portion of web to be moved into contact with, held against and released from the surface. Several flexible members may be provided in the path at spaced apart positions. Synchronizing means may be employed to ensure synchronized station of the movement of the member or members.

摘要： A shutter assembly (130), mounted in a motion film projector (100), that includes a shutter (120) secured to a mounting bracket (240), which houses a pair of trucks (244). The mounting bracket (240) slidably houses one of the trucks (244) to accommodate for the trucks (244) passing over straight and curved portions of the track, or shutter path. The mounting bracket (240) securely houses a first truck (244) and slidably houses a second truck (244). The trucks (244) are rigidly clamped to the conveyor (104). This configuration permits the shutter (120) to be stably coupled to the conveyor (104) while permitting the shutter assembly (130) to travel along both straight and curved paths. The trucks (244) are configured to ride in a raceway (122, 124), which supports the trucks (244) and maintains the trucks (244) on a truck path. The trucks (244) include rollers (126), which roll along an elongated channel formed in the raceway (122, 124), or alternatively include air bearings (506) for carrying the truck (244) along a pressurized raceway (800).

摘要： A flow camera apparatus (10) operable for photographing large original documents in continuous, moving fashion includes a camera (74) located within the housing (12). An aperture adjustment mechanism (86) allows adjustment of the camera aperture from the outside of the housing (12) without opening the housing (12). The iris adjustment mechanism also allows the aperture to be changed during photographing of a document. The apparatus includes lamps (214, 216 and 218) for illuminating the document during photographing and a "T" mask assembly (22) provided with baffles (204 and 208) for allowing only light reflected from the document to enter the image path (88) to the camera (74). The apparatus (10) also includes precisely balanced detectors (126) for detecting entry of a document into the apparatus (10).

摘要： A reloadable film canister (11) includes a light-tight enclosure (18) with an aperture for dispensing film therethrough. A spool (23) of film may be loaded into the enclosure, and may be removed when the film is dispensed. In one embodiment of the invention, an encoder (28) (field modulating) disk is included as part of the canister. In another embodiment the encoder disk (24) is affixable to the film spool and loadable with the film spool into the canister. The spool is mountable in the enclosure for rotation therein and for dispensing, at each step of a stepper motor (43), a predetermined length of film corresponding to the motor's step size. The encoder disk has a plurality of uniformly-spaced, peripherally-arranged segments (25) (elements) detectable by an external detector (36) (sensor), the detector and the stepper motor operating under control of a microprocessor (41). Upon rotation of the spool and dispensation of film, the disk provides information, via the detector, to the microprocessor enabling the microprocessor to determine, from the number of motor steps and number of segments detected during rotation, the diameter of the film roll and the length of undispensed film remaining in the canister.

摘要： A projector having a rolling loop film transport mechanism is provided with a film decelerating cam unit (52) that is located in advance of the aperture of the projector. Deceleration pins (66) carried by a pair of vertically spaced arms (62) that project from the cam unit, engage in upper and lower marginal perforations in the film and travel with the film towards the aperture and decelerate the film as each frame is advanced. The cam unit includes two cams (56, 58), one of which causes the decelerating motion of the pins, and a return motion in the reverse direction, while the other cam (58) causes the pins to advance and retract into and from the film path respectively. By positively retracting the pins, their return movement against the direction of film travel can take place independent of the motion of the film. As compared with the prior art, acceleration forces and resultant stresses on the cam are reduced and the cam unit can operate at higher frame rates and/or with smaller rotor gaps.

摘要： A method and an apparatus for pre-loading a single use camera with film (24). The camera is pre-loaded in non-darkroom with the back cover assembled to the camera without exposing any substantial portion of the film (24). The camera has a film advance mechanism (22) that employs a manual advance wheel (40) which is rotated in opposing directions to pre-load film from a film cassette (26) in the camera to a film spool compartment and to wind film back into the film cassette (26) from the film spool compartment (16) as exposures are taken. The film advance mechanism (22) also opens and closes the film cassette's light lock door (28) and employs a film sensor to disable the film advance mechanism (22) from operating the light lock door (28) when film is present in a film path (68a) of the camera. The battery (90) is inserted inside the film spool compartment (16) to minimize the camera size.

摘要： In an alternate eye 3-D motion picture projection apparatus of the rolling loop type, light projection is accomplished by the combination of focal plane shutters that are coupled to the rotor of the projector and a supplementary shutter arranged to trim the projected light so that discrete "left eye" and "right eye" images are projected. Various embodiments are disclosed in which a rotary blade shutter is located at the stop of the projection lens. Where there are two projection lenses (32, 32), a single blade or two counter-rotating blades (68,70) trim the light projected through both lenses.
