Abstract

A system for opening and closing a door within a cabinet is provided. The system includes a motor in communication with a controller to automatically open and close a door. A first plate fixed to the motor shaft to rotate with rotation of the motor shaft, the plate comprises a slot disposed therein. A first leg extends from a door that extends through the slot. A second leg extends from the door. A first sensor moves based upon rotation of the motor shaft, wherein the first sensor can detect relative motion between the motor shaft and the door, wherein when the motor shaft is rotated in the second direction and the first sensor detects relative motion between the motor shaft and the door, the first sensor sends a signal to the controller, wherein upon receipt of the signal the first sensor discontinues sending the second signal to the motor.
