A note discriminating apparatus includes first and second detectors for detecting the characteristics of a note, a reference level generating section for generating a reference level signal by utilizing the output of the first detector, and a level detecting section for comparing the reference level signal with the outputs of the second detectors to recognize the note. The apparatus further includes a means which, when a note conveyed through the note inlet to the note discrimination position is detected as abnormal, conveys the note back to the note inlet, and conveys the note to the note discrimination position again.
