Even a visually handicapped person can identify bank notes that he (she) has with him (her), and can use such notes without danger of wrongly pay. A note is fed manually into the device to detect its magnetic and optical patterns. Then, a comparison calculation is executed to judge whether or not the data thus detected are within the range between the upper and lower limits of the typical values stored in advance for each of the circulating bank notes. He (she) can know the kind of the note or that the note cannot be identified. The device is driven by dry cells and portable even by a visually handicapped person. This device comprises a CPU (1), ROM (2), RAM (3), A/D converter (4), amplifier (5), pattern detection sensor (6), rotary encoder (7), DC-DC converter (8), timer IC (9), and buzzer (10). |
