Abstract
An optical sensing device for detecting plural optical features of valuable papers is provided that comprises first and second photocoupersandorandpositioned in the vicinity of and on the opposite sides of a passagewayfor guiding the valuable paper. Each of first and second photocouplersandorandhas a light emitting elementfor emitting a light, and a light receiving elementfor selectively receiving the light from the light emitting elementso that each light receiving elementcan receive lights reflected on and penetrating the valuable paperfor detection of multiple optical features from the valuable paper. Thus, the optical sensing device can derive plural optical scanning patterns by means of less number of light emitting and receiving elements to improve accuracy in valuable paper validation; can pick out optical patterns for different colors printed on valuable paper by means of plural lights of different wavelength irradiated on a same scan line or area on valuable paper; and can utilize inexpensive light emitting and receiving elements to reduce cost for manufacture.
