A feeding apparatus, disposed in a detecting room having therein a target object, includes a fixing element, at least one target sensing unit, a rotating element, a driving module, and a control unit. The fixing element includes at least one lens disposed on a sidewall of the fixing element. The lens converges an infrared radiation in the detecting room onto the target sensing unit which then generates a position signal corresponding to the target object. The rotating element is disposed on one side of the fixing element. The rotating element includes a discharge channel. The driving module is connected to the rotating element. The control unit is coupled to the target sensing unit and the driving module to receive a position signal from the target sensing unit and control the driving module to drive the rotating element according to the position signal.
