Patent ID: 8851473

Claim:
A sheet matter separation mechanism, comprising: a banknote picking wheel assembly and a banknote separating wheel assembly driven by a banknote separating wheel motor synchronously; a driving wheel assembly of post-banknote separation driven by a driving wheel motor of post-banknote separation; and a banknote separating rubber being fitted on a banknote separating wheel of the banknote separating wheel assembly, the banknote separating rubber touching a medium for one time with the help of rotation of the banknote separating wheel for one circuit; wherein if a front of a currently-separated medium reaches a front boundary of a preset velocity adjusting region in front of the banknote separating wheel and a rear of the currently-separated medium leaves a rear boundary of the preset velocity adjusting region, a relative velocity between the banknote separating wheel motor and the driving wheel motor of post-banknote separation is adjusted, such that a preset medium separation spacing is kept between a rear of the currently-separated medium and a front of a next-separated medium; and wherein a driving synchronous belt of post-banknote separation is connected between the driving wheel assembly of post-banknote separation and the banknote separating wheel assembly.
