Abstract: PURPOSE: To make it possible to detect the same point without increasing the number of sensors and to prevent the variation of a data level due to the wrinkles or the like on the paper money by discriminating and judging the paper money by the sum of imput data to reflected light receiving elements arranged on the side of a light emitting element. CONSTITUTION: In a detection part 10 for deteting a paper sheet such as paper money carried along a carrying route, a light emitting element 11 and a light receiving element 12 are oppositely arranged with the carring route interposed and reflected light receiving elements 13, 14 are arranged in the front and back positions of the element 11 on the same side as the element 11. The element 11 and the lower side element 12 constitute a sensor for transmitted light and the elements 11, 13, 14 constitute a sensor for reflected light to detect the same point by these sensors. A control part finds out the sum of outputs obtained by the elements 13, 14 and detects a pattern based upon the sum data.  Thereby, even when a paper sheet is in a waved state due to a fold or the like, the influence of variation in the data level due to the wave is not exerted and the generation of a shadow is prevented.

Patent JP-H05175062-A (JP)
Title: Transformer
Inventor: OGURA SHINZO
IPC: H01F27/36
Filed: 1991-12-20
Abstract: PURPOSE:To detect an electric current under test with high accuracy even when an external conductor in which a large electric current flows exists in its neighborhood by a method wherein a connecting conductor which connects ends of the same polarity of shield windings is formed as a ring-shaped body with which the outer circumference of an iron core is covered and whose width is prescribed. CONSTITUTION:A first connecting plate 7 is formed to be ring-shaped; it is installed at the outside of shield windings 4a to 4d in such a way that they are covered. A ring-shaped body 8 which is a second connecting plate and which is provided with both sidewalls is installed at the outside of the first connecting plate 7 so as to be concentric with the first connecting plate 7. Thereby, a leakage inductance is small and an induced current flows easily. Since the outer circumference of an iron core 2 is covered with the connecting conductors 7, 8, a magnetic flux by an electric current flowing in an external conductor 6 creeps into the iron core through the connecting conductors 7, 8. However, the connecting conductors 7, 8 can make the induced current sufficient to offset the flux density flow easily. Consequently, even when the external conductor in which a large electric current flows exists in its neighborhood, an electric current under test can be detected with high accuracy.
