<p>A hidden line detecting device is provided to detect the hidden line written on a security paper by using a plurality of light-sensitive sensors. A hidden line detecting device comprises a hidden line sensing module and a hidden line sense data processing module. The hidden line sensing module senses the reflecting light when a light is irradiated on one inner side of an external case(10). The hidden line sensing module consists of a ultra-violet ray lamp and a reflecting light sensor. The ultra-violet ray lamp emits ultra-violet rays according to the power applied by the hidden line sense data processing module. The reflecting light sensor senses the reflecting light irradiated by the ultra-violet ray lamp. The hidden line sense data processing module located inside the external case receives the sensing data from the hidden line sensing module.</p> |
