Patent number: 5159377Abstract: An image magnification control device for a camera. Control focal length required to maintain an image magnification constant is computed based upon defocus information detected by analyzing a light that passes through a photographic lens. In case a focal length of the photographic lens moves out of a range wherein the set image magnification can be obtained, various options, such as a shutter-release lock operation, can be executed depending upon the chosen design of the camera.Type: GrantFiled: February 4, 1991Date of Patent: October 27, 1992Assignee: Asahi Kogaku Kogyo Kabushiki KaishaInventors: Noboru Suzuki, Shigeo Toji, Masahiro Kawasaki

Patent number: 5153627Abstract: A film cassette comprises a film spool supported within a lighttight shell for rotation in an unwinding direction to thrust a filmstrip coiled about the spool to the exterior of the shell and for rotation in a winding direction to return the filmstrip to the interior of the shell. According to the invention, a locking device is connected to the spool and the shell for preventing rotation of the spool in the unwinding direction, and is enabled for such purpose in response to rotation of the spool in the winding direction. This prevents a photographer from reusing the cassette in a camera after the filmstrip is fully exposed. The locking device can be manually defeated to reuse the cassette in the camera when the filmstrip is only partly exposed.Type: GrantFiled: February 15, 1991Date of Patent: October 6, 1992Assignee: Eastman Kodak CompanyInventor: Patricia A.
