A machine for automatically dispensing a selected container from a store of containers and for automatically storing a container returned to the machine. The machine includes an array of storage bins for storing a plurality of containers. Each bin has a bottom with an elongated slot. The bins are arranged in a plurality of vertically-stacked, horizontal rows, with a horizontal passage between each horizontal row and a vertical passage connecting the horizontal passages. Each container is stored in a respective one of the bins. A controllable arm is mounted for relative movement through the horizontal and vertical passages between a first position for dispensing a selected container and for receiving a returned container, and a second position corresponding to a selected one of the bins. The controllable arm is mounted for movement through a respective one of the bins by passage through a respective one of the elongated slots. A control mechanism is responsive to an input signal which corresponds to one of the respective bins and is connected to the arm for moving the arm through the vertical and horizontal passages between the first and second positions and for moving the arm through the elongated slot of the bin at the second position for one of removing a selected container from and inserting a returned container into such bin.
