    • PROBLEM TO BE SOLVED: To provide a compact and inexpensive coin discriminator that performs authenticity determination on the basis of image information obtained by imaging, as well as based on materials and thickness.SOLUTION: A coin input through a coin slot rolls on a coin path. The coin path is irradiated with light from a surface projector in parallel with the coin path through a half mirror. The light reflected from the coin rolling on the coin path is reflected by the half mirror, guided in parallel with the coin path, and reaches an imaging element through a condenser lens. Image information captured by the imaging element is compared with reference information to determine the authenticity of the input coin. If a forged coin is determined, the coin is returned without opening a gate. If an authentic coin is determined, the gate is opened to receive the coin.
    • 要解决的问题:提供一种紧凑且廉价的硬币鉴别器,其基于通过成像获得的图像信息以及基于材料和厚度进行真实性确定。

      解决方案:通过硬币槽输入的硬币在硬币路径上滚动。 硬币路径通过半反射镜与硬币路径平行地来自表面投影仪的光照射。 从在硬币路径上滚动的硬币反射的光被半反射镜反射,与硬币路径平行地引导,并通过聚光透镜到达成像元件。 将由成像元件拍摄的图像信息与参考信息进行比较,以确定输入硬币的真实性。 如果确定硬币,则硬币在不打开门的情况下返回。 如果确定正宗的硬币,门打开以接收硬币。 版权所有(C)2012,JPO&INPIT
