• key input means for successively entering commodity prices and the amount of money received from a customer by a keying operation;
• note identifying means for identifying the denomination of a note to be identified as received from the customer;
• arithmetic control means for adding said commodity prices and calculating the sum of said amount of money entered through said key input means and the amount of money identified by said note identifying means, said arithmetic control means comparing the sum of said commodity prices and said sum of money with each other to calculate the amount of change;
• display means for displaying said sum of said commodity price, said sum of money received from the customer and said amount of said change;
• and
• memory means for memorizing said sum of said commodity price, said sum of money received from the customer and said amount of said change;
• wherein said identifying means comprises a rectangular base plate for supporting the note to be identified, a first group of photo-electric sensors disposed on the base plate for generating first signals when blocked from light by the note, a second group of photo-electric sensors disposed on the base plate in opposition to said first group for generating second signals when blocked from light by the note, a light source disposed above the base plate for projecting light onto said first and second groups of photo-electric sensors, first note width detecting means for receiving said first signals and generating a third signal representing the width of the note, second note width detecting means for receiving said second signals and generating a fourth signal representing the width of the note, receiving means for receiving said third and fourth signals and responsive thereto for determining the kind of the note, and further detecting means for detecting the quantity of oblique orientation of the note in response to said first and second signals and for generating a fifth signal when the quantity of oblique orientation of the note exceeds a predetermined value.
