ABSTRACT:
A newspaper display machine has a container and an access door pivotably mounted to the container. The door includes a transparent window large enough to expose the full length and full width of a newspaper. A pair of pressure plates are pivotably mounted on the inside of the door for retaining a display newspaper against a rear surface of the window. Closure springs bias the pressure plates and access door to their closed positions. The container is provided with retainer openings which receive lower corners of the pressure plates when the pressure plates and the access door are all in their opened positions, in order to hold-open the pressure plates and access door against the closure biases of the springs.
