    • An image detector for bank notes is provided which can be made at low cost and in small size. The image detector comprises a pair of detector units 13 includes a first image detection sensor 24 which detects an image of a first detection area mounted on one side of a detector unit 18, a first light emitting device 27 which irradiates light towards the first detection area, and a second light emitting device 31 which irradiates light towards a second detection area mounted on one side of the unit main body 18 but in a different location from the first detection area, a pair of detector units is disposed so as to oppose one another across a bank note transportation path 12, in a manner which enables the image detection sensor 24 of one of the detection units 13 to detect an image of the second detection area of the other of the detection units 13.
    • 检测器具有两个具有检测两个相应检测区域(Z1,Z2)的图像的电荷耦合器件(CCD)传感器(24)的检测单元(13)。 发光体(27,31)朝向相应的区域照射光。 这些单元布置成跨越纸币(S)运输路径(12)彼此相对,以使得一个传感器能够检测一个区域的图像,而另一个传感器检测另一个区域的图像。
