Abstract

A sheet-feeding apparatus. The sheet-feeding apparatus comprises a shaft, a sheet-feeding arm and an elastic member. The sheet-feeding arm has a passive surface and rotates around the shaft. The elastic member has a driving surface contacting the passive surface at a first point and exerts a first torque to the shaft when the sheet-feeding arm at a first position. When the sheet-feeding arm is at a second position, the elastic member exerts a second torque to the shaft by the driving surface contacting the passive surface at a second point, wherein the first torque probably equals to the second torque.
