The paper accommodating device is for accommodating paper sheets to be processed by the paper processing apparatus. The paper feeding apparatus is for feeding the paper sheets accommodated by the paper accommodating device one by one to the paper processing apparatus. The paper feeding apparatus includes a pickup roller, a delivery roller, a pair of feeding rollers, a detection device, a transmission gear assembly, a drive motor and a controller. The detection device detects a leading edge and a trailing edge of the paper sheet delivered by the paper feeding apparatus. In particular, the paper feeding apparatus is a simple-configuration, light-weight and compact component and capable of feeding paper sheets accurately. During feeding operation of the paper feeding apparatus, the rollers of the paper feeding apparatus are driven rotating in respective direction or stopped rotating so as to feed the paper sheets accurately.
