Optical sensing device for detecting optical features of valuable papers
摘要：
An optical sensing device for detecting plural optical features of valuable papers is provided that comprises first and second fourfold assemblies longitudinally arranged before and behind along a passageway (13) for guiding the transported valuable paper (64);
said first fourfold element comprising first and second photocouplers (5, 6) positioned in the vicinity of and on the opposite sides of the passageway (13);
said second fourfold element comprising third and fourth photocouplers (9 and 10) positioned in the vicinity of and on the opposite sides of the passageway (13); and
each of said first, second, third and fourth photocouplers (5, 6, 9, 10) having a light emitting element (20, 22, 30, 32) for emitting a light, and a light receiving element (21, 23, 31, 33) for selectively receiving the light from the light emitting element (20, 22, 30, 32) and reflected on or penetrating the valuable paper (64).
摘要（中）：

提供了一种用于检测有价值纸张的多个光学特征的光学传感装置，其包括沿着用于引导传送的有价值的纸张（64）的通道（13）纵向布置的第一和第二四重组件; 所述第一四重元件包括位于所述通道（13）的相邻两侧的第一和第二光电耦合器（5,6）; 所述第二四重元件包括位于所述通道（13）的相邻侧面附近并位于所述通道（13）的相对侧上的第三和第四光电耦合器（9和10）。 并且具有用于发光的发光元件（20,22,30,32）的所述第一，第二，第三和第四光电耦合器（5,6,9,10）中的每一个，以及光接收元件（21,23， 31,33），用于选择性地接收来自发光元件（20,22,30,32）的光并反射或穿透有价值的纸张（64）。
