摘要:
A lens-fitted photographic film package comprising a light-tight film casing having an exposure opening, a rolled film disposed on one side of the exposure opening in the light-tight casing, a removable light-tight container having a film winding spool therein disposed on the other side of the exposure opening in the light-tight film casing, and an externally operable film winding member for winding the rolled film around said film winding spool of the light-tight film container. The lens-fitted photographic film package is assembled by the steps of winding film withdrawn from a light-tight film container in a roll in a darkroom; loading the rolled film and the light-tight film container in separate respective receiving chambers formed in a main body section of the lens-fitted photographic film package; and fixing a back cover section to the main body section so as to assemble light-tightly the lens-fitted photographic film package.

A lens-fitted film unit with an electronic flash is provided with a film container cover member covering a film container receiving chamber of a film unit housing which is opened to remove a film container from the film container receiving chamber and a battery cover member covering a battery receiving chamber of the film unit housing. The battery cover member is operationally integrated with the film container cover member so as always to be opened when the film container cover member is opened to remove the film container containing an exposed film from the film unit housing.

A lens-fitted photographic film package comprises a light-tight film case having exposure structure, a rolled film in a film roll receiving chamber disposed on one side of an exposure frame in the light-tight case, and a removable film container having a film winding spool therein disposed on the other side of the exposure frame in the light-tight film case. A member is provided for causing the film to be advanced smoothly without getting scratched, for preventing the film roll from becoming loose, and for preventing the film from being gouged by a film exit slot of the film roll receiving chamber.

A photographic film package has a taking lens, an exposure member, and a rolled film, with their associated elements, contained in a light-tight film container as a unit. The taking lens consists of either an aspherical or a spherical single-element lens preferably made of plastic material and is designed to have a focal length f and a lens speed F defined by the following conditions:F.gtoreq.f.sup.2 /150F.gtoreq.34.3-0.75fF.ltoreq.16

The present invention is characterized by repeatedly AD converting in a time series an output of each light sensitive element, and at the same time an added value or a mean value of each one of said AD converted values is obtained so that such added value or a mean value is used as an output of each light sensitive element. According to the present invention, an influence of flickering of an artificial light source can be eliminated and at the same time a light measuring computation with a high level of accuracy can be made with a higher speed than that in a conventional method, and particularly in a light measuring apparatus housing a number of light sensitive elements a light measuring computation with a high level of accuracy can be made in a by far faster speed than that in a conventional method.

A specialized polymeric peroxide is copolymerized with vinyl type monomers in the presence of organic liquid, thereby obtaining a solution of a copolymer having peroxy bonds therein.This solution is admixed with vinyl type monomers which are different in composition from the ones used in the first copolymerization, and the resultant mixture is subjected to block copolymerization.The obtained block copolymer solution is admixed with an organic liquid which exert solubility to one of polymers of the vinyl type monomers which are employed in the first or second copolymerization, whereby a non aqueous system liquid dispersion is obtained.This dispersion contains a block copolymer in a high concentration and it also is splendid in uniformity of dispersion and dispersion stability.

A telephoto lens having a long focal distance is disposed at an upper location at the side portion of a camera body, and the light passed therethrough is reflected sidewardly of the camera body by a pivotable first mirror. Disposed at an upper location of an exposure station is a second mirror which redirects the light from the first mirror to a third mirror disposed in front of and to the side of the second mirror. Below the third mirror and in a front part of an exposure station, a pivotable fourth mirror is disposed. Mounted at an upper location of the side portion of the camera body is an L-shaped movable lens barrel, in which an ultra telephoto lens having an exceptionally long focal length, and a fifth mirror for reflecting the light passed through the ultra telephoto lens toward the second mirror are disposed. The movable lens barrel is associated with the first mirror. When the movable lens barrel is adjacent the camera body, the camera is in telephotographing mode, and when the movable lens barrel is horizontally pulled up, the camera is in ultra telephotographing mode. In front of the fourth mirror, there is disposed a wide angle lens having a short focal distance. When the fourth mirror is displaced to be in a horizontal state, the camera is in a wide angle photographing mode.

A millimeter-wave radar (obstacle detecting device) detects an obstacle in front of a traveling vehicle. A driving-state detecting device detects a specified driving state of the vehicle. An operation-timing changing device changes an operation timing of operational devices according to detection results of the driving-state detecting device. A control unit (operation control device) operates the operational devices (warning device, brake device, seatbelt pre-tensioner) at the above operation timing. Thus, the safe and smooth vehicle driving can be attained without an improper detection of the obstacle.

A liquid crystal display unit has a transmissive liquid crystal plate having a number of pixels arranged on a two-dimensional basis, on which an image is formed, and a light source unit emitting beams of light of a plurality of luminescent colors for irradiating said liquid crystal plate from back. An interface circuit receives an image signal representative of a color image to sequentially form on said liquid crystal plate a plurality of separation images in which the color image is separated in association with the plurality of luminescent colors of said light source unit. The interface circuit causes said light source unit to flash with a luminescent color associated with a separation image formed on said liquid crystal plate in synchronism with a sequential formation of the separation images onto said liquid crystal plate. Beams of light emanated from the light source unit and transmitted through the liquid crystal plate reproduce an image.
