Abstract
A file storage apparatus (10) has a string or stack of drawer elements (14) vertically disposed along a side. A mechanical blocking shaft (28) is disposed on one side of the drawer (14) to allow only one drawer to be opened while blocking the remaining drawers preventing opening. A locking bar (62) is disposed on a second side of the drawers (14) for locking all of the drawers closed in response to an electrical access circuit (72) and for unlocking all of the storage units (14). An actuator member (72) interacts between the access circuit (72) and the locking bar (62) for moving the locking bar (62) between an unlocked and locked position.
