Abstract
A security door assembly for use in an automatic document dispensing device having a user access compartment for conveying documents to a user through an opening in the user access compartment is provided. The security door is pivotally mounted to the user access compartment for rotation between a first position in which the security door closes the opening in the access compartment to prevent documents from being withdrawn therefrom and a second position in which the security door is contained within the user access compartment to allow the user to gain access to the compartment through the opening therein for removal of documents. The door assembly further includes structure for rotating the security door between the first and second positions. Structure is also provided for locking the security door in the first or closed position and for automatically opening the security door when a foreign object is encountered in the path of rotation of the security door.
