Abstract

PURPOSE:To provide the merchandise storage device without causing overload on a motor even when a merchandise container is full of merchandise. CONSTITUTION:When the load of a merchandise A placed on an merchandise mount plate 70 is smaller than a specific weight (determined by the energizing force of a spring 72), the mount plate 70 slants down toward a push-up member 40. Consequently, the merchandise A on the mount plate 70 rolls toward the push-up member 40 and carried out without being left on the mount plate 70. Further, when the load of the merchandise A placed on a mount plate 60 is larger than the specific weight, the mount plate 70 slants up toward the push-up member 40. Consequently, the merchandise A on the mount plate 70 tends to roll to behind the merchandise container 10, so the load of the merchandise on the mount plate 70 is placed on the opposite side to the push-up member 40, so that the load placed on the push-up member 40 decreases.
