A banknote position detection device is provided in a banknote channel. The banknote position detection device comprises: a first photoelectric sensor disposed at a banknote channel inlet, a second photoelectric sensor disposed at a banknote channel outlet, a third photoelectric sensor disposed at a banknote channel middle portion. The first photoelectric sensor comprises a light emitting end, a light receiving end, a first reflector and a second reflector, wherein the light emitting end and the light receiving end are disposed symmetrically at two side ends at an upper inlet of a lower channel plate of the banknote channel, and are configured to detect whether a banknote reaches the banknote channel inlet. The second photoelectric sensor comprises a light emitting end, a light receiving end, a third reflector and a fourth reflector, wherein the light emitting end and the light receiving end are disposed symmetrically at two side ends at an upper outlet of the lower channel plate of the banknote channel, and are configured to detect whether the banknote reaches the banknote channel outlet. |
