Abstract: A two-dimensionally driven lock and key are provided. The two-dimensionally driven lock has a lock core having sliders and a block. The sliders are movably and rotatably mounted in the lock core. Each slider has a recessed portion and a non-circular positioning portion. The block has protrusion portions selectively received in the recessed portions. The key has positioning dimples identical to the positioning portion in shape. When the key is inserted into the lock core, the positioning portions match to the positioning dimples respectively and the protrusion portions face to the recessed portions. An unlocking method includes inserting a key into a lock core to make the recessed portion and the protrusion portion face and align to each other by moving and rotating the sliders. Therefore, a location of the recessed portion can vary on the slider in two dimensions, and thus making ulocking very difficult.

Abstract: A storage and dispensing device for stacked articles has a sliding panel, a main frame mounted on the sliding panel, two holders respectively mounted on the main frame and two clip assemblies respectively mounted on the holders. When the sliding panel slides toward one direction, the two holders slide toward each other and the two clip assemblies slide toward reverse directions. Therefore, one stacked articles falls on the holders. Afterwards, when the sliding panel slides toward another direction, the two holders slide toward reverse directions and the two clip assemblies slide toward each other to hold the other stacked articles. Consequently, the stacked article that falls on the holders further falls on and dispenses users with the stacked article.
