When the passive gear rotates, the floating gear revolves around the passive gear. A plurality of driving rollers are driven by a first motor. A plurality of driven rollers are driven by driving rollers, respectively. A prop assembly includes a brace arranged in the base, a prop axel engaged in the brace, a twist arm fixed at the prop axel and having a plurality of teeth for contacting with the floating gear, a swimming arm sleeved and firmly engaged with the swimming arm and a spring component installed on a support board of the swimming arm. The passive gear drives the floating gear descending and ascending. There are two motors provided in the sheet-handling apparatus in order to simplify the structure of the sheet-handling apparatus.
