ABSTRACT:
The invention relates to vending machines for dispensing of a single copy of a printed publication one-at-a-time. The vending machine is self contained, is provided with a power source, a driving motor and a control unit for operation of the vending machine. An inclined platform plate mounted within the vending machine carries a plurality of media units, while a push plate forces the media units toward a dispensing channel located adjacent a forward edge of the platform plate. When a single copy of the media unit moves through the dispensing channel, a light sensor sends a signal to the control unit which causes reversal of movement of the push plate, thereby preventing accidental dispensing of the next copy of the media unit by gravity. After an entire inventory of the media units resting on a platform plate has been dispensed, a limit switch sends a signal to the control unit allowing vending of a display copy. A tilt switch detects tilting of the vending machine beyond a predetermined limit and actuates a chute block gate member that blocks the dispensing channel to prevent dispensing of the media units in case of vandalism.
