    • A fingerprint input apparatus includes a light source 2 for emitting light and a fiber optic plate 3 having a finger contact surface with which a finger 1 is brought into contact in order to pick up a fingerprint image of the finger 1. The light from the light source 2 is at first introduced into an inside of the finger 1, is scattered within the inside of the finger 1, and comes out of the finger through the surface of the finger 1 as outgoing light. By the use of the outgoing light, the fingerprint image is formed. The light source 2 is disposed so that the light from the light source 2 enters into a substantial center of a part of the finger 1 including a first joint on a palm side and that the light source 2 is contacted with the finger 1.
    • 指纹输入装置包括用于发光的光源2和具有与手指1接触的手指接触表面的光纤板3,以便拾取手指1的指纹图像。 来自光源2的光首先被引入到手指1的内部,散布在手指1的内部,并且通过手指1的表面作为出射光从手指外出。 通过使用出射光,形成指纹图像。 光源2被布置成使得来自光源2的光进入手指1的一部分的大部分中心,该手指的一部分包括在手掌侧的第一关节,并且光源2与手指1接触。
