Abstract
Abstract In a card supply magazine with a device for retaining and transferring cards, the walls of a loading ramp are turned angularly about a vertical axis relatively to the walls of a lower reception magazine. The cards situated at the bottom of a stack in the ramp rest on two support surfaces and on a rotatable roller. When the roller is driven in rotational movement by a motor, cards driven frictionally by the roller rotate about the said axis and fall into the lower magazine from which they are extracted. A vibrator arranged at the bottom of the stack facilitates the fall of the cards into the lower magazine. The motor is controlled by a device monitoring the level of the cards in the lower magazine.
