    摘要： A CCD image sensor is fixed on a Y-direction stage that is supported on an X-direction stage. When a piezo driver supplies voltage to an X-direction piezo element and a Y-direction piezo element, the CCD image sensor is moved in X and Y directions. The X-direction position sensor and the Y-direction position sensor detects the position information of the CCD image sensor in X and Y direction respectively, and send the position information to the piezo driver. The piezo driver sets a target movement of the CCD image sensor, and detects the actual movement of the CCD image sensor from the position information. The piezo driver adjusts the output voltage to the X-direction piezo element and the Y-direction piezo element such that the target movement becomes the same as the actual movement.

    摘要： A method and mechanism are disclosed for driving optical members in an optical apparatus, in which cam means formed on a lens barrel are provided with insensitive zones, so that the lens barrel is rotated to drive a diaphragm for adjustment of its diaphragm stop after the lens has been moved to the insensitive zones, then the lens barrel is rotated in the reverse direction with the diaphragm being maintained at its adjusted diaphragm stop, and thereby power variation and/or focussing of the lens as well as adjustment of the diaphragm stop are achieved using a single drive source. A cylindrical cam 40 is provided within a stationary lens barrel 30 so as to be rotatable around an optical axis S. The cylindrical cam 40 is formed with cam slits 41 each having insensitive zones 42 at longitudinally opposite ends thereof so that an enlarging lens 20 can not be further moved back and forth when lens driving pins 27 lie in these insensitive zones 42. Diaphragm driving plates 43, 44 are mounted on the inner wall of the cylindrical cam 40 so that rotation of the cylindrical cam 40 causes these diaphragm driving plates 43, 44 to drive the diaphragm driving pin 24 while the lens driving pins 27 lie in the insensitive zones 42 and thereby to vary a diaphragm stop of an iris diaphragm 22. Once the diaphragm stop has been varied, the cylindrical cam 40 is rotated in the reverse direction to move the enlarging lens 20 to a desired position for desired power variation and/or focussing.

    摘要： The present invention concerns a photographic projector-printer assembly for projecting a negative film F onto a photographic paper C through a projecting lens L for photographic printing, in which the projecting lens L is integrally provided on its object side with an optical path-splitting prism P for splitting on the optical axis the light for photometric and monitoring purposes, thereby eliminating such a printing ability reduction problem as is found in a system designed to put a reflecting mirror in and out and providing a solution to image distortion and measurement accuracy drop problems. In addition, the optical path-splitting prism P is designed to be adjustable in the optical axis direction and around the optical axis in terms of its position with respect to the projecting lens L, so that the optical axis of the assembly can be kept in alignment with that of an associated photometric and monitoring system.

    摘要： A verification screen is displayed by using information obtained by prescanning. On the basis of a print magnification, fine scanning conditions are computed, and a determination is made as to whether or not a density of an image obtained by prescanning is greater than or equal to a predetermined value. If the density of the image obtained by prescanning is not greater than or equal to the predetermined value, fine scanning is carried out in accordance with fine scan conditions. If the density of the image obtained by prescanning is greater than or equal to the predetermined value, the image is read at a charge accumulating time which is longer than a charge accumulating time during fine scanning and at a conveying speed which is slower than a conveying speed during fine scanning.

    摘要： The improved image inputting apparatus for reading the image recorded on a transmission original comprises: a light source; an image sensor for photoelectrically reading the light that has issued from the light source and which has been transmitted through the original; an imaging lens for permitting the transmitted light to be focused on the image sensor; a focusing device for automatically adjusting a focus of the imaging lens; and a control device for controlling the focusing device before starting the reading of a new image group such that only the first frame of the image group is subjected to one-step automatic focusing or two-step automatic focusing consisting of coarse and fine adjustments whereas the other frames are not subjected to focusing but image reading is performed adopting the focus state of the first frame or are subjected to automatic focusing comprising only fine adjustment. The apparatus can allow projecting light that bears the image recorded on strips or slides to form a satisfactorily and accurately focused image on an image sensor such as CCD sensor, and also permit rapid and efficient image reading and thereby contribute to an improvement in the efficiency with which output images can be produced.
