    • The device contains a conveyor with at least one conveyor belt (3, 7, 11, 15) for loose items (25), the surface of which has a brightness which is as complementary as possible to that of the surfaces of fixed regions (1, 5, 9, 13, 17) visible near it and an electronic scanning device (ZK, L1, L2) extending approximately transversely (X) to the conveying direction (Y) over the width of the conveyor belt and the visible surfaces of the fixed regions for the linear detection of the brightnesses (I(x,y)). There is also a program-controlled computer (PC) which stores a sequence of the brightnesses (I(x)) occurring over the width (X) of the conveyor belt (3,...) and visible surfaces of the fixed regions (1,...) in the absence of a loose item (25) in a first store (SP1) and places current brightnesses (I(x,y)*) in a second store (SP2) as long as differences occur on the comparison with the corresponding values or values from the stored sequence (I(x)).
    • 该装置包括与至少一个输送带(3,7,11,15),用于片状物品(25),其表面具有固定到相邻的暴露表面的亮度在区域(1,5,9,13,17)尽可能亮度包括互补的输送机 且a是大约横向(x)至在所述传送带的宽度和延伸电子扫描装置中的固定区域的可见表面的输送方向(Y)(ZK,L1,L2)的亮度强度值的线状的检测(I(X,Y))。 另外,程序控制的计算单元(PC),其中在第一存储器(SP1)是一个序列关于传送带(3,...)和所述固定区(1 ......)的可见表面的宽度(X)(在不存在一块良好的 25)亮度强度值存在的(I(X))存储,并在第二存储器(SP2)存储的当前的亮度强度值(I(X,Y)*),只要(在相应的值或者与从所存储的顺序值组比较,我 (X))的偏差。
