Title: Device for recognizing reflecting optical element and device for recognizing storage medium
Inventor: MATSUDA MAMORU
IPC: G06K17/00
Filed: 1999-09-16
Abstract: PROBLEM TO BE SOLVED: To quickly discriminate whether an object such as a card provided with a reflecting optical element is a forgery or not with a high recognition capability by a relatively simple device constitution and a recognition algorithm. SOLUTION: A recognition device 1 is provided with an illumination means 4 which throws illuminating light, an optical sensor 5 which picks up the image of reflected light from a reflecting optical element 2 as a two-dimensional pattern, a signal processing part, an A-D converter, a memory, CPU, etc. The illumination means 4 and the optical sensor 5 are arranged in such positions and directions that the angle of reflected light from the reflecting optical element 2 may be an angle of reconstruction peculiar to the reflecting optical element 2, and plural picture data different by reflection patterns are obtained from reflected light, and the picture data are compared with corresponding reference data to discriminate whether the reflecting optical element 2 is a forgery or not.  In this case, it is convenient that plural evaluation points are set on a photographed two-dimensional matrix and the signal intensity obtained by reflected light of each illumination is binarized with a slice level at each evaluation point.

Title: Copying machine
Inventor: YAMAUCHI YASUSHI
IPC: G03G15/00
Filed: 1990-09-28
Abstract: PURPOSE:To shorten time required for copying by specifying the circulating method of an original when the both-side copying of plural one-side originals is carried out. CONSTITUTION:In the both-side copying from the one-side original, when the number of the originals is odd, the copying of the original of the last page is carried out at the beginning of the first circulating period of the original. Consequently, the original of two-sheets ahead of the last page and except one-sheet following to the original of two-sheets ahead of the last page, can be copied for the second circulating period of the original. In other words, the copying of the originals of the last page and each even page is carried out, for the first circulating period of the original, and the copying of the originals of each odd page except the last page is carried out for the second circulating period of the original. Thus, it is unnecessary that the circulating of the original is tentatively interrupted to allow the original to stand by at an optical scanning position during the switching period of a paper feeding source, so that copying processing time can be shortened as a whole.

Abstract: PURPOSE:To improve the accuracy in centering of the inside and outside diameters, by molding an outer periphery retaining frame first when the outer periphery retaining frame and an inner periphery retaining frame, both formed of a resin material, are insert-molded separately in a disk magnet having an axial hole in the central part. CONSTITUTION:Both obverse and reverse surfaces of a disk magnet 1 having an axial hole 2 formed in the central part are ground, and an outer periphery retaining frame 3 is molded on an outer peripheral edge 1a ground and an inner periphery retaining frame 4 on the inner peripheral edge 1b of the axial hole 2, separately from each other, by using an insert of resin material and by means of a mold. On the occasion, the outer periphery retaining frame 3 is molded first so that the outer peripheral part of the magnet 1 be compressed to oppose an internal pressure, i.e. an expansion force, generated in molding of the inner periphery retaining frame 4, and thereby to prevent cracks or damages. According to this method, only plane grinding of both obverse and reverse surfaces is required even when sintered ferrite is used for the disk, and no damage is caused by an impact force when the disk magnet is fitted to an electromagnetic apparatus.
