Title: Exposure device for photosensitive film
Inventor: INOUE YUTAKA
IPC: H04N1/04
Filed: 1985-08-08
Abstract: PURPOSE:To reduce the size, weight, energy consumption, and cost and improve the exposing speed of the titled exposure device, by using an element formed by arranging numerous swinging mirrors which deflect a luminous flux in at least two directions. CONSTITUTION:A DMD 27 reacts electromechanically in response to a signal and a mirror swinging section 13 swings. The light A of a lighting system emitted from a light source 21 illuminates the mirror array section of the DMD 27 in a slit-like condition after passing through lighting optical systems 22-26. The irradiated light A is deflected in the direction of reflecting light C by the mirror and intercepted by a light intercepting plate 30, when each mirror swinging section of the mirror array on the DMD 27 is turned OFF. Accordingly, the light A does not reach a photosensitive film 31. When each mirror swinging section is turned ON, the light A is reflected in the direction B and made incident to an image forming lens 29. As a result, a dot pattern corresponding to the mirror swinging sections is formed on the photosensitive film 31. Similarly, movement of the film 31 and exposure in accordance with a prescribed signal are repeated.

Filed: 1992-06-30
Abstract: PURPOSE:To enhance the reliability of operation of a valve mechanism by constituting an air valve of a valve element covering an opening via a viscous sealant, and providing at least either one of the valve element and the viscous sealant with a clearance holding function, the air valve eliminating pressurization and decompression inside a container such as an ink tank of an inkjet printer. CONSTITUTION:A circular opening 2 is provided through a support 1 which is made by using part of a container, and a thin film 3 serving as a valve element is provided over the support 3 to cover the opening 2 via a viscous sealant 11. A cover for protecting the thin film 3 from the outside is provided in a position distant from the surface of the thin film 3 if necessary. To provide the function of holding the clearance between the support 1 and the thin film 3, the surface of the thin film 3 and/or the support 1 is made uneven to provide a rough surface. Or powder is mixed in the viscous sealant 11. When the internal pressure of the container is raised relative to the external pressure, the thin film 3 is pushed up toward the outside of the thin film 3 and the thin film 3 releases part of the viscous sealant 11 between it and the support 1 and forms a narrow passage, whereby the valve mechanism slows the buildup of the internal pressure.
