摘要： A zoom lens barrel has a lens unit with both functions of zooming and focusing, comprises a first cyindrical member having a zoom guide groove (or zoom cam) corresponding to a zooming orbit of displacement of the lens unit with both the functions of zooming and focusing and a second cylindrical member having a focus guide groove (or focus cam) for displacing the lens unit with the functions of zooming and focusing along an optical axis for focusing. The focus guide groove or focus cam is non-linear and has an area inclined with respect to the optical axis to permit the relative displacement of the first and second cylindrical members to each other in the optical axis direction necessary for the focusing of a given object to be held substantially constant irrespective of the status of zooming and also permit the displacement of the lens unit with both the functions of zooming and focusing for focusing to be varied according to the status of zooming.

摘要： A waterproof operation mechanism of an interchangeable lens barrel having an operation member which is rotatably set around a periphery of the interchangeable lens barrel. A button engages with the operation member such that the button penetrates the operation member and protrudes outward from the operation member. The button functions to fix the operation member at a predetermined rotation position and to release the operation member from the predetermined rotation position. The interchangeable lens barrel includes a knurled part around its periphery, the knurled part being made of an elastic material and having a protruding portion integrally formed therewith to cover the button. Further, the operation member includes a fitting groove on a periphery of the operation member to prevent the knurled part from being displaced in a direction of an optical axis of the lens barrel.

摘要： A multiple point focus detection camera capable of acquiring focus detection data on objects within a photographer's field of vision is operable in an automatic or a manual mode, and can be automatically switched to the automatic or manual modes as a default upon the occurrence of certain events in order to reduce the likelihood of errors during photography. Automatic operation can be enabled (i.e., is the default) upon power-up or changing of lenses. Manual operation can be enabled when lens data indicates that a lens used most often by a professional photographer is in use. Either mode (automatic or manual) can be set as a default mode, which can be selected when the camera is placed in a self timer mode. A default mode change feature can be provided to allow a user to select automatic or manual as the default mode.

摘要： A multi point focal detection camera is switchable between an automatic mode and a manual mode. An automatic focusing system focuses a movable lens system having a lens on a selected one of multiple focus detection areas in accordance with either focus detection data or a focus detection area selection lever. A CPU enables the selected one of the multiple focus detection areas to be changed to another of the multiple focus detection areas without changing the operation mode. Once the lens system is focused on the selected focus detection area, the selected focus detection area can be changed by displacing the focus detection area selection lever within a predetermined period of time. If the selected focus detection area is changed to another of the multiple focus detection areas, the automatic focusing system focuses the lens system on the new focus detection area.

摘要： Provided is a highly reliable semiconductor device by giving stable electric characteristics to a transistor in which a semiconductor film whose threshold voltage is difficult to control is used as an active layer. By using a silicon oxide film having a negative fixed charge as a film in contact with the active layer of the transistor or a film in the vicinity of the active layer, a negative electric field is always applied to the active layer due to the negative fixed charge and the threshold voltage of the transistor can be shifted in the positive direction. Thus, the highly reliable semiconductor device can be manufactured by giving stable electric characteristics to the transistor.
