| 101 | Reflection type equal magnification image forming element | JP7630480 | 1980-06-06 | JPS572017A | 1982-01-07 | FUKUSHIMA YOSHIO |
| PURPOSE:To make a device small-sized, by using an image forming element having two symmetrical partial spherical surfaces which are equal in the radius of curvature, convex in the front and adjacent in the vertical direction, on the front surface, and having one partial cylindrical reflection surface which has a center axis in the vertical direction and is convex in the rear, on the rear surface, relating to an image forming element to be used for an exposure optical system of a copying machine. CONSTITUTION:An image forming element 11 is a transparent body, and is formed in the shape of a rectangular parallelepiped having the front surface consisting of two spherical surfaces 12, 13 which are adjacent and equal in the radius, and having the rear surface consisting of a right cylindrical reflection surface 14. The reflection surface is manufactured by means of Al vapor deposition, etc., and an upper surface 15, a lower surface 16 and both sides 17, 18, of the image forming element is coated in black so that light absorption is elevated. When an image formation element array 19 which has been prepared in this way is used for an exposure optical system of a direct type copying machine, the image forming element array 19 is placed horizontally under an original table 22 on which an original 21 is put, and in its front is placed a mirror 23 having a shape which has made two reflection surfaces meet at right angles, so that its right-angles apex is directed toward the center part of the array 19. | ||||||
| 102 | Optical imaging element | JP4433180 | 1980-04-04 | JPS56140302A | 1981-11-02 | IGUCHI TOSHIYUKI |
| PURPOSE:To form an optical imaging element which is small in size, is inexpensive and permits long focusing by forming prism surfaces on one side and lens surfaces on the other side, and arranging these in an array shape. CONSTITUTION:An imaging element 10 consists of a prism array 11 of which the aperture parts 12 are provided with curvature, wherein the curvatures of the aperture parts 12 act as lenses. Hence, this element 10 forms images in the manner similar to that of conventional in-prism lenses and similarly, the focuses are made longer. The lens surfaces are arranged densely or by leaving intervals. Since such elements 10 are formed integrally and simultaneously by using plastic materials or the like, they are formed inexpensively, and the focuses are made longer. | ||||||
| 103 | In-prism lens array | JP2138680 | 1980-02-22 | JPS56117201A | 1981-09-14 | IGUCHI TOSHIYUKI |
| PURPOSE:To improve the quality of a picture by preventing circumferential picture parts from overlapping each other in an array column direction by setting the angle of view of each lens to a minimum value of demmand in the column direction and by increasing it in the vertical direction as much as possible. CONSTITUTION:Between lens 21 and prism 22, shielding plate 23 is arranged which has the rectangular opening part consisting of a horizontal side less than the diameter of lens 21 and a vertical side equal to the diamter of lens 21, and array of plates is provided in direction (x) of projection surface 24. Thus, an in-prism lens whose angle of view is small in column direction (x) of the array and large in vertical direction (y) is obtained. An in-prism lens array with the great angle of view is used to prevent circumferential picture parts from overlapping in the array column direction, so that deterioration in picture quality in the column direction is prevented. | ||||||
