Patent number: 5486886Abstract: A variable angle flash for a photographic camera has a flash tube and a reflector that are relatively movable along an optical axis. A linear motor in the camera drives a follower connected with one of the flash tube and reflector members for moving the flash tube (or reflector) along the axis to vary the illumination angle of the flash. Optionally, the motor is a linear form of ultrasonic wave motor of which the follower forms a movable portion. An elastic body engaging the follower and fixed to the camera case carries piezoelectric elements that undulate the body when subjected to ultrasonic alternating currents, causing the body to move the follower and drive the flash tube (or reflector) along the optical axis and thereby vary the illumination angle.Type: GrantFiled: March 21, 1994Date of Patent: January 23, 1996Assignee: Eastman Kodak CompanyInventor: Mikhail Vaynshteyn

Patent number: 5473402Abstract: A film processing system that removes film strips from their cartridges, splices the strips together for processing and printing, and then separates the strips for return and reattachment to the same cartridge from which they were removed. The empty cartridges are maintained during processing in a magazine in the same sequential order and corresponding batch as the spliced film strips, to facilitate matching of the film strips and cartridges at the end of the process. According to other features, the spliced roll of film strips is unwound and rewound after development, once for electronically scanning the film strips to capture electronic representations of the developed images, and again for optically printing the developed images onto photographic paper. The film strips include magnetically recorded information, representing conditions of camera exposure, that are captured during scanning before printing.Type: GrantFiled: December 22, 1993Date of Patent: December 5, 1995Assignee: Eastman Kodak CompanyInventors: Francis C.

Patent number: 5465129Abstract: A film transport mechanism for a camera is powered by a clock-like spiral spring to advance the film. The spring is rewound during manual rewinding of the film into its canister. A separate belt and pulley drive carries the force of spring rewinding. The separate drive also actuates laterally movable (swinging) idler gears on pivot arms to disengage the canister film spool from the drive when the take-up spool is being driven in the forward, film winding, direction and to disengage the take-up spool from the drive when the film spool is being driven in the reverse, film rewind, direction. The film is thus not subjected to the forces required for rewinding the spring. An escapement mechanism is provided to control the speed of film transport to a relatively constant value in spite of the torque variations inherent in the spiral wound spring.Type: GrantFiled: March 21, 1994Date of Patent: November 7, 1995Assignee: Eastman Kodak CompanyInventor: Mikhail Vaynshteyn

Patent number: 5398089Abstract: A takeup spool drive for motorized camera film winding mechanisms and the like has a clutch mechanism with simplified components including a driver, a driven member such as a pinion gear and a takeup spool. The driver has lugs that drive the pinion gear in both directions with lash. Fingers on flexing arms of the driver engage internal teeth of the takeup spool to drive it in a forward film takeup direction. The fingers are disengaged by lash takeup in the reverse direction that causes inward flexing of the arms and allows free running of the spool. In addition to selective engaging and declutching drive of the takeup spool, the mechanism fingers re-engage the internal teeth upon momentary forward rotation for lash takeup and thereby lock the free running takeup spool when the motor is stationary after a winding movement, such as when the film registers in a film gate.Type: GrantFiled: February 23, 1994Date of Patent: March 14, 1995Assignee: Eastman Kodak CompanyInventor: Wayne E.
