A lens movement mechanism for digital camera includes a lens set which has a composite lens and a Charged Couple Device built therein, a first movement member for turning the lens set angularly left or right, and a second movement member for turning the lens set angularly up or down. The first movement member includes a bracket piovtly holding the lens set and a gear set for turning the bracket and the lens set left or right angularly. The second movement member includes a slant block with a slope surface contact with a rear end of the lens set so that when the slant block is moved transversely, the lens set will be tilted up or down angularly. Therefore the lens set may be turned left or right, up or down smoothly and precisely without a user's hand moving the lens set directly. The lens may be prevented from hand smearing. Higher photo quality may be achieved.

A computer controlled system and method of using the system for control of shipping a quantity of product either domestically or internationally. The system comprises a number of user input stations for entering a shipping request. Product release information stored in the computer is added to the request which is transmitted t a product storage unit, a printer, and an exit control station. The product storage unit selects the product requested. The printer prints a product release form which can include a customs declaration form and/or a digital authentication stamp if desired. The product is prepared for shipping and the product release form is attached. The product and the product release form is checked at the exit control station. The product is then shipped or corrective action is taken.
