<p>A sheet-type medium handling technique, specifically an apparatus applicable in a self-service financial device for reliable sheet-by-sheet gathering and separation of an entire stack of banknotes. The apparatus comprises: a pickup roller component (2), for use in friction-dispensing a banknote in contact therewith among an entire stack of banknotes; a reversal roller component (1), for use as a barrier when separating an entire stack of banknotes so as to prevent more than one banknote from being friction-dispensed and for use in pinching of banknotes gathered sheet-by-sheet; and, a separator roller component (3), which is arranged opposite the reversal roller component (1) to form a gap channel for dispensing a single sheet of banknote, for use in providing output power to single sheets of banknotes friction-dispensed or gathered and fed-in by the pickup roller component (2). The reversal roller component (1) comprises a reversal roller (12), where the reversal roller (12) is fitted onto a reversal roller shaft (13) via a one-way bearing (122), and at least one wing roller (11) having asymmetric sprockets and arranged coaxially in parallel with the reversal roller (12), where the wing roller (11) and the reversal roller shaft (13) are fixedly arranged. The apparatus is capable of solving fixed-point wearing of the surface of the reversal roller (12).</p> |
