Photoelectric detection device, for recognizing transparent adhesive tapes pasted on bank notes, on note sorter

The utility model relates to a photoelectric detection device, in particular to a photoelectric detection device, for recognizing transparent adhesive tapes pasted on bank notes, on a note sorter. The device aims at solving the problem that conventional mechanical equipment cannot completely classify and detect bank notes pasted with adhesive tapes and bank notes with folded corners or other foreign bodies. Luminescent plate placement ports and receiving plate placement ports are arranged on an upper fixed plate and a lower fixed plate respectively, the upper fixed plate and the lower fixed plate are respectively arranged on an upper retaining plate and a lower retaining plate in a bank note passage of the note sorter, an upper luminescent plate and an upper infrared light receiving plate are arranged in the luminescent plate placement port and the receiving plate placement port on the upper fixed plate respectively, and a lower luminescent plate and a lower infrared light receiving plate are arranged in the
