An inlet door apparatus for a waste inserting facility using an air transferring method is provided to put large sized wastes regardless of sizes and kinds by having the inlet door whose sectional area is circular and large. A collection pipe line is vertically placed in a construction. A branch pipe line is extended from the pipe line to the predetermined position of each floor. A door(2) is hinged at a chute frame(4) to be opened and closed. The door is controlled by a control box(10). A latch of the inlet door apparatus locks a latch(20) of the door by being supported by a return spring. A solenoid is excited by a signal of the control box to move the latch backward. A sensor is interfered to the latch at the door closed position for switching work.
